Abstract

The invention discloses a mechanical unlocking device of an electromagnetic lock.The mechanical unlocking device comprises a lock shell (1).The upper portion in the lock shell (1) is a mechanical unlocking area (2), and the lower portion in the lock shell (1) is an electromagnetic unlocking area (3).The electromagnetic unlocking area (3) is internally provided with a spring bolt (5) with the top end extending to the mechanical unlocking area (2).The top end of the spring bolt (5) extends into a lock catch (4).A lock cylinder (6) is movably arranged in the mechanical unlocking area (2).A lock hole (7) is formed in the center of the lock cylinder (6).A lock cover (13) covers the lock shell (1).A plurality of through holes (14) are formed in the lock cover (13).The through holes (14) include the real through hole (21) communicated with the lock hole (7) and the anti-theft through holes (22) all connected with an alarm device.The mechanical unlocking device is high in anti-theft level, safety and practicability.

Description

technical field [0001] The invention relates to a mechanical unlocking device for an electromagnetic lock, belonging to the technical field of locks. Background technique [0002] The electromagnetic lock uses the principle of electromagnetism. When the current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction force and tightly absorb the adsorption iron plate to achieve the effect of locking the door. The setting of the mechanical unlocking device of the electromagnetic lock is to use the mechanical unlocking key to open the electromagnetic lock when the electronic key fails in actual use. [0003] Existing mechanical unlocking devices for electromagnetic locks are simple in structure and low in anti-theft level. Thieves can open the electromagnetic locks with commercially available iron wires or screws. Reduce the security level of the electromagnetic lock, making the electromagnetic lock expensive and impractical. [0004] I...
