The electric tool is a kind of small electric motor or electromagnet as the power. A small tool that drives the working head through a transmission mechanism. There are a wide variety of electric tools, complete functions, easy to carry, and simple to use. They have been widely used in various industries and have entered the family. Electric tools are divided into handheld and movable There are two types. Hand-held power tools are more flexible, convenient and widely used. Many varieties have become necessary tools for production and life. There are many brands of power tools. According to the functions and uses of power tools, they are divided into nine categories. . Mainly are the following nine categories: Electronic Tools,Hand Drill,Electric Hammer,Electric Saw,Angle Grinder Rugao Yaou Import & Export Trade Co., Ltd , https://www.ntyaoumachinery.com
We know that each magnet has two poles, one north pole (N-pole) and one south pole (S-pole). The magnets have the same sex repulsion and the opposite sex sucks. Magnetic locks make use of this characteristic of magnets. The unlocking tools made of permanent magnets (magnetic beads) are also called "electronic locks".
â—‹ Magnetic Padlock The inside of the magnetic padlock has two long strips, one is a movable plate and the other is a fixed plate. When the lock beam locked by the padlock is strongly pulled, the lock slams the bump on the movable plate so that the movable plate has a force to move in the direction of the fixed plate, if the movable plate can move toward the fixed plate at this time. Distance, the lock can open. In the longitudinal direction of the two long strips, four holes are drilled into each plate. One end of each of the four magnetic beads is fixed with a relatively thin brass wire, and the brass wires on the four magnetic beads are respectively inserted into the four holes in the fixing plate.
The four holes on the fixing plate are thinner than the magnetic beads than the brass wires, so that the magnetic beads can be oscillated in all directions on the fixing plate, but after being fixed in the lock, they cannot be moved longitudinally due to the restriction of the lock body. One end of the magnetic beads without a fixed brass wire faces the key slot outside the lock, and the other end of the magnetic ball with the brass wire fixed faces the movable plate. Due to the magnetic interaction of the four magnetic beads inside the lock, the brass wire at the end of the magnetic beads is not aligned with the four holes on the movable plate (or is not concentric). When a pulling force acts on the locked locks At this time, the lock slams the bump on the movable plate. Although the movable plate is subjected to the force to move toward the fixed plate at this time, the brass wire is not aligned with the hole on the movable plate, that is to say yellow. The copper wire will resist the movable plate and can restrict the movable plate from moving toward the fixed plate so that the lock cannot be opened.
When the proper key is stuck in the key slot outside the lock, the magnetic beads in the lock will be attracted by the magnetic beads inside the lock (must be opposite magnetic poles inside and outside), making the four yellow inside the lock. The copper wire is driven by the magnetic beads, which are respectively aligned with the holes on the movable plate. When a pulling force acts on the locked lock plate, the protruding plate on the movable plate is pressed, and the force of the inner spring of the lock is overcome. , move to the fixed plate, because at this time the four brass wire can enter the hole in the movable plate, the movable plate can move a certain distance to the fixed plate, and the lock can be opened. In order for the brass wire to smoothly enter the hole in the movable plate, the end of the brass wire is pointed. When the lock lever is aligned with the lock hole, the lock lever is pulled by the inner spring of the lock and pulls the lock lever into the lock hole. At the same time, the movable plate is also returned to the original position by the force of the spring, so that the lock is closed.
○ Magnetic door lock The magnetic lock (including the magnetic drawer lock) is similar to the basic structure of the “10†marble lock. The basic structure is also composed of a lock cylinder (plunger) and a lock cylinder housing (lock cylinder). The pinball lock has a pinball chamber, and the magnetic lock has a “magnetic bead room†(the magnetic bead room is what I call it); the pinhole on the pinball lock cylinder is a through hole (the pin can be seen from the key hole), and the magnetic lock cylinder The magnetic beads on the holes are blind holes (the magnetic beads are not visible from the keyhole of the magnetic lock), and the depth of the blind hole on the magnetic cylinder core is shorter than the height of the magnetic beads, and part of the magnetic beads is not inserted when an appropriate key is not inserted. Can enter the blind hole in the lock cylinder, and the other part is exposed outside the lock cylinder. It is in the hole of the lock cylinder. This is the state of the magnetic lock.
The pinball lock is a pin tumbler, the magnetic lock is a magnetic ball tumbler, the tumbler locks the upper and lower beads, the magnetic lock also has upper and lower magnetic beads; the tumbler lock uses the spring force of the spring to control the tumbler to keep the locking ball in the static state, and the magnetic lock The two magnetic beads in each magnetic ball room are of the same polarity. Repulsion of the same sex is the magnetic force pushing the lower magnetic beads into the blind hole of the lock cylinder to maintain the locking state of the locking static state.
The ball lock is inserted into the keyhole using a suitable key, and the ball is directly contacted with the ball to overcome the elastic force of the spring to unlock all the ball latches. The magnetic lock is to use a suitable magnetic key to use the magnetic beads in the key and the magnetic beads in the lock. The repulsive force pushes out all the magnetic beads in the blind hole of the lock cylinder in a non-contact manner, releasing the locking effect of each magnetic bead and unlocking; the position of the tampine in each “10†lock head of the same model is fixed (eg, Each row of beads differ by 90°), but the length of each ball is different, and the height of the used key tooth is the same. The position of the magnetic ball tumbler inside each magnetic lock of the same type is different, but each The lengths of the magnetic beads are the same, the polarity of the beads in each bead room is different, and the position and polarity of the magnetic beads on the key to open the lock correspond.
The installation of the magnetic lock utilizes the principle of electro-magnetic production. The magnetic lock has the advantages of traditional key locks and is more safe and reliable. How to correctly install a magnetic lock?
The following is a detailed description of the magnetic lock installation method.
â—‹Surface Mounting Method for Opening Doors First Step: Open the cover with a screwdriver first, and then use the hex wrench to punch the board, ready to install Step 2: Take out the installation board, fold the board along the dotted line, and put the board into the required installation The position of the lock, and then make a hole in the hole to be punched.
The third step: A After the iron plate is fixed, insert the Hexagon socket screw into the iron plate, place the rubber washer between the two metal washers, and then set it on the Hexagon screw. Insert the iron plate into the three holes in the door and insert the mushroom head from the other side of the door. Use a hex wrench to lock the iron plate on the door. Fix the B side board by fixing the board to the previously punched door frame with the two round head screws (fixed in the long hole in the board). Note: Do not lock the edge plate so that it can move forward and backward to facilitate the correction of the position. C. Correct the position of the side plate so that the side plate and the heel plate are properly positioned so that the lock body can be in close contact with the successor plate. D. Lock the main body of the lock and the round head screws on the side plates to lock the side plate, then lock all the countersunk screws, then remove the round head screws and drill holes in place for wiring. Finally, use a hex wrench to lock the lock body on the side plate.
Step 4: Wire according to instructions in the instructions.
Step 5: Cover the cover and insert the small aluminum cylinder into the screw hole of the lock body.
Installation Precautions When installing the successor plate, do not lock it so that it can sway slightly to facilitate the natural combination with the lock body.
â—‹ Surface Mounting Method for Inner Doors When the door is opened for surface mounting, auxiliary accessories are required to assist in the installation. We use high-quality, decorative, imported aluminum to make this mounting assembly: the Z&L bracket. Each Z&L bracket contains three aluminum fittings, of which the longer one L1 is used for the distribution lock body; the other two shorter Z2 and Z3 are provided for the iron plate. Z2 is installed on the door, there are five counterbores on the side for fixing on the door; Z3 is for fixing the iron plate, there are three holes on the side, the center hole should be with the center hole of the iron plate. Align.
The following describes the installation method.
a. Firstly put the L1 bracket in the Z&L bracket on the locked position, and use a self-tapping screw to fix it on the door frame or the wall surface.
b. Use a hex wrench to lock the lock body on the L1 bracket.
c. Position the Z2 bracket on the door corresponding to the position of the L1 bracket.
d. After the iron plate is inserted into the three holes of the Z1, it is falsely fixed, and then the door is closed so that the magnet and the iron plate closely match with each other to determine the connection position of Z1 and Z2. (The relative positions of Z1 and Z2 can be adjusted according to the thickness of the door).
e. Lock the Z1 and Z2, and then fix the helix plate to the Z1 with the M8*25 Allen screw (pass the screws, iron plate, washer and rubber washer one by one).
f. If it is a double door, two Z&L brackets can be used.
For the wooden door, if the size of the door rib is enough to be embedded in the lock body, the installation is very simple, just dig a suitable slot, the lock is locked after the lock is buried, and the general construction personnel see the lock will be installed. The door frame of the aluminum alloy door is generally hollow. For this feature, we design two installation methods.
A, lining wooden block method: In the door frame, put a piece of wood suitable for lining, and then lock the screws. This method is convenient and easy to install. Most of the actual installation uses this method.
Bã€Using mounting fittings method: This method is to use our accessories (four-hole iron plate + U-shaped iron) to make installation easier.
Installation Precautions Pay attention to the dimensions of the door ribs when doing flush mounting to be slightly larger than the size of the selected lock.
Glass door installation method There is a method of installing aluminum alloy (or other material) package frame glass door: glass door to do embedded installation can generally use 10001 series magnetic door lock, this is my company's unique best for installation in the glass The lock on the door, whether your door is open or open, double open free door can be installed. The installation method is the same as the flush installation of ordinary doors.
★ Installation Notes Glass doors need to be equipped with aluminum alloy box, because the lock suction and distance requirements are less than 6 mm, so the distance from the door to the door frame is required to be less than 6 mm, the floor spring needs to use stable quality, otherwise it will affect the positioning of the lock. .
maintenance:
The maintenance of magnetic door locks is relatively simple compared to other locks, as long as the surfaces of the iron plate and the lock body are kept free from impurities, so please wipe the surface with a non-abrasive cleaner periodically.

Constructing the first line of defense: working principle and installation of magnetic lock
The design of the magnetic lock (or electromagnetic lock) is the same as that of the electromagnet, which uses the principle of electro-magnetic. When the current passes through the silicon steel plate, the electromagnetic lock will generate a strong suction force to firmly attract the adsorption iron plate to achieve the effect of locking the door. . As long as the small current electromagnetic lock will generate great magnetic force, the access control system that controls the electromagnetic lock power supply will identify the personnel and then turn off the power, and the electromagnetic lock will lose its suction to open the door.
