an electromagnetic lock

Abstract

The invention relates to the technical field of lockets and in particular relates to an electromagnetic lock. The electromagnetic lock comprises a lock hook, a lock catch assembly, a lever assembly and a driving mechanism, wherein the lock catch assembly is provided with a locking position which is clamped with a lock body after the lock hook is inserted into the lock body, and an unlocking position for enabling the lock hook to be released from the lock body and popping out the lock hook; the lever assembly comprises a lever body and a second elastic part connected with the lever body; the lever body is provided with a first limiting end; the lock catch assembly is provided with a second limiting end; the first limiting end of the lever body is clamped with the second limiting end when moving to the locking position on the lock catch assembly and is released from the second limiting end under the action of a driving force; the driving mechanism is provided with a force application part which is adaptive to an inclined plane, which is molded at a part far away from the first limiting end, of the lever body and a driving assembly for providing the driving force for the force application part; the force application part is suitable for applying an acting force toward a deformation direction of the second elastic part and an acting force along a movement direction of the force application part. The electromagnetic lock provided by the invention is stable and has good safety performance.
