[0002] As an important security protection equipment, electromagnetic locks play a key role in many fields, such as access control systems, safes, industrial equipment protection, etc. However, when some electromagnetic locks are installed, they are generally firmly installed on the door frame by relying on a mounting plate, and the electromagnetic locks are fixed to the mounting plate with the help of bolts. This makes the disassembly and assembly of the electromagnetic locks very cumbersome, which is not conducive to the later maintenance of the electromagnetic locks, and is not practical and cannot meet the needs of users.

[0003] After searching, Chinese patent announcement number: CN221143909U discloses a new electromagnetic lock mounting plate, including an L-shaped mounting plate, a movable groove is opened in the middle of the surface of the L-shaped mounting plate, a threaded rod is arranged in the movable groove, one end of the threaded rod extends out of the movable groove and is fixed with an adjustment dial, the surface of the threaded rod is threadedly connected with two symmetrically arranged threaded blocks, one side of the two threaded blocks is fixed with an L-shaped clamping plate, and an electromagnetic lock body is arranged between the two L-shaped clamping plates. This device rotates the adjustment dial forward and backward, the adjustment dial drives the threaded rod to rotate forward and backward, the threaded rod drives the two symmetrically arranged threaded blocks to move closer or farther from each other, and the threaded block drives the two symmetrically arranged L-shaped clamping plates to move closer or farther from each other, so that the pin and the positioning hole complete the plug-in or disengagement operation, thereby limiting and fixing the electromagnetic lock bodies of different sizes, and the installation and disassembly are simple and convenient, saving labor costs.

[0004] In the above technology, although the convenience of disassembling the electromagnetic lock in the later stage can be improved through its designed structure, it still has certain defects when in use. When installing, the electromagnetic lock is installed by rotating the bidirectional threaded rod to control the movement of the clamping plate. The clamping plate is designed to be L-shaped.

[0032] Reference Figure 1 - Figure 2 , Figure 4 The buffer assembly includes a fixed block 61 that allows the hinged rod 65 to rotate stably. The fixed block 61 is fixedly connected to the front side of the inner wall of the bottom end of the movable shell 32. The inner wall of the fixed block 61 is hinged with a hinged rod 65. The outer wall of the hinged rod 65 is slidably connected with a sleeve 62 that ensures the stable sliding of the hinged rod 65. The rear surface of the hinged rod 65 is provided with an air hole 64. The air hole 64 is composed of a straight airway, an arc airway and two groups of oblique airways to ensure that the gas flows on its inner wall with a certain resistance, which can buffer the impact force from the outside.

[0033] Reference Figure 2 - Figure 3The disassembly assembly also includes a pull plate 31, by pulling the pull plate 31, the guide plate 33 can be driven to move, the pull plate 31 penetrates and is slidably connected to the front surface of the fixed plate 2, the guide plate 33 is fixedly connected to the rear surface of the pull plate 31, the upper surface of the guide plate 33 is provided with a through slot 34, the through slot 34 has a certain slope to ensure that when the guide plate 33 moves, the slide bar 35 will move along the slope of the through slot 34, the outer wall of the left top end of the slide bar 35 is slidably connected to the inner wall of the through slot 34, the outer wall of the slide bar 35 is sleeved with a spring 36, the spring 36 always drags the moving shell 32 to move to the right through its own elasticity, to ensure the stability of the limit of the block 37, one end of the spring 36 is fixedly connected to the inner wall of the slide slot 5, and the other end of the spring 36 is fixedly connected to the left surface of the top end of the moving shell 32.

[0034] Reference Figure 3 - Figure 4 The inner wall of the sleeve 62 is elastically connected with a piston block 66 through a spring 2 63. The spring 2 63 can buffer the external impact force through its own elasticity, and can also ensure that the piston block 66 is quickly reset. The piston block 66 is fixedly connected to the rear surface of the hinge rod 65. When the piston block 66 moves on the inner wall of the sleeve 62, it will squeeze the air on its inner wall and have a certain resistance, which can buffer the impact force. The piston block 66 is connected to the inner wall of the sleeve 62, one end of the spring 2 63 is fixedly connected to the rear surface of the piston block 66, and the other end of the spring 2 63 is fixedly connected to the inner wall of the sleeve 62.

[0035] Reference Figure 3 - Figure 4 There are multiple groups of articulated rods 65, which are symmetrically arranged with the center line of the sleeve 62 as the symmetry axis. Arranging multiple groups of articulated rods 65 can improve the buffering effect. The rear ends of the multiple groups of articulated rods 65 are hinged to the inner wall of the front side of the top end of the block 37. There are multiple groups of air holes 64, which are opened on the rear surface of the piston block 66. The multiple groups of air holes 64 opened on the rear surface of the piston block 66 are straight airways and are connected with the air holes 64 to ensure the smooth flow of gas.

[0036] Working principle: when installing the lock body 1, first use the bolt holes provided at the left and right ends of the fixing plate 2 to fix the fixing plate 2 on the door frame with the screws. Then, place the lock body 1 under the movable shell 32, push the lock body 1 so that the card block 37 is inserted into the inner wall of the card slot 4 until the upper surface of the lock body 1 contacts the lower surface of the movable shell 32. In this process, since the lower surface of the card block 37 is set as an inclined surface, when the lock body 1 is pushed upward, the upper surface of the lock body 1 will squeeze the inclined surface of the card block 37, so that the card block 37 moves, and the card block 37 will drive the movable shell 32 to move, and the movable shell 32 will squeeze the spring 1 36 until the card block 37 is completely inserted into the inner wall of the card slot 4 provided on the upper surface of the lock body 1. At this time, under the elastic action of the spring 1 36, the spring 1 36 drags the movable shell 32 to move to the right, thereby driving the card block 37 to move to the right, and the bottom end of the card block 37 is stuck in the inner wall on the right side of the bottom end of the card slot 4, so as to achieve a stable connection of the lock body 1.

[0037] When disassembling, just pull the pull plate 31, the pull plate 31 will drive the guide plate 33 to move, and then the slide bar 35 will move along the inclination of the through slot 34, and the slide bar 35 will drive the movable shell 32 and the block 37 to move until the block 37 moves to the left side of the inner wall of the slot 4, and then the lock body 1 can be disassembled.

[0038] In daily use, when the lock body 1 is subjected to external impact force, the impact force will drive the card block 37 to slide on the inner wall of the movable shell 32. At this time, the multiple groups of hinged rods 65 will rotate between the fixed block 61 and the card block 37 respectively, and the connection distance between the hinged rod 65 and the sleeve 62 will also change. At this time, the hinged rod 65 will drive the piston block 66 to move on the inner wall of the sleeve 62, squeezing the air in the sleeve 62, and the squeezed air will flow through the air hole 64. Since the air hole 64 opened on the rear surface of the hinged rod 65 is composed of a straight airway, an arc airway and two groups of oblique airways, the gas flowing in the air hole 64 will produce a certain resistance, thereby buffering the impact force. At the same time, when the piston block 66 moves, it will also compress the spring 2 63. The spring 2 63 can also buffer the external impact force through its own elasticity. When the impact force disappears, the elasticity of the spring 2 63 makes the piston block 66 quickly reset, ensuring that the buffer component can continue to play a role.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
