Description

Magnetic lock with protection function Technical Field The utility model relates to the technical field of magnetic locks, in particular to a magnetic lock with a protection function. Background The existing magnetic lock generally comprises a lock body, a fixed plate and a suction plate (also called an electromagnet block, a relay iron plate or an attaching plate), wherein the fixed plate is arranged on a door frame, the lock body is arranged on the fixed plate through screws, the suction plate is fixedly arranged on a door, the lock body is matched with the suction plate for use so as to realize opening or closing of the door, however, in the actual use process, the screw for fixing the lock body is easy to loosen due to long-time use, the lock body falls down, the magnetic lock is damaged, even the potential safety hazard that the magnetic lock falls down to injure personnel is caused, moreover, the magnetic lock cannot timely send out a warning signal after loosening or falling down, cannot be timely noticed by related personnel, and the magnetic lock has single function and poor use safety. Through searching, chinese patent publication No. CN219672371U discloses a magnetic lock with a smashing prevention function, in the patent, through the arrangement of a protective sleeve frame, a damping spring, a protective top plate, a support column, a limiting slide plate, a connecting frame and a buffering cushion, the front end of the damping spring is provided with the protective top plate which is lapped on the surface and the back of a magnetic lock main body, when the outer protective sleeve frame is smashed, the inner magnetic lock main body is buffered and protected through a plurality of groups of damping springs and damping dampers in the protective sleeve frame, the limiting slide plates on two sides keep stable to the inner magnetic lock main body and prevent the magnetic lock main body from shifting when the magnetic lock main body shakes, and the connecting frame and the buffering cushion absorb part of force of smashing by external force, so that the inner magnetic lock main body is protected, the effect of adding a plurality of buffering protections to the outer part of the magnetic lock main body is achieved, and the operation of workers is facilitated; However, when the device is used, though the impact force on the magnetic lock generated when the magnetic lock is impacted is reduced through the structural combination of the protective sleeve frame, the damping spring and the like, and the magnetic lock body is further protected, the device can only protect the magnetic lock body and reduce the vibration influence of the magnetic lock body, however, the door body for installing the magnetic lock is vibrated to loosen the screw at the installation position of the magnetic lock and the door body, and the magnetic lock is further damaged by falling.
