AI Technical Summary
The locking pin and sliding rod of a traditional electromagnetic lock are an integral structure. After being subjected to pressure for a long time, the sliding rod structure is prone to deformation and damage, which in turn damages the electromagnet unit.
The locking pin and slide rod are designed as separate structures, connected by snap-fit buckles and slots. The slide rod drives the locking pin to move. When the locking pin is under pressure, it does not transmit the pressure to the slide rod. The locking pin is supported and guided by the guide bushing and bearing bushing.
This effectively prevents the slide bar from deforming under pressure, maintains the structural integrity of the electromagnet unit and the slide bar, and extends the service life of the electromagnetic lock.
