Abstract

The invention discloses a mechanical unlocking device for an electromagnetic lock.The mechanical unlocking device for the electromagnetic lock is characterized in that the mechanical unlocking device comprises a lock shell (1), the upper portion in the lock shell (1) serves as a mechanical unlocking area (2), the lower portion in the lock shell (1) serves as an electromagnetic unlocking area (3) which internally comprises a lock tongue (5), the top end of the lock tongue (5) extends to the mechanical unlocking area (2) and extends into a lock catch (4), a rotor (6) is arranged in the mechanical unlocking area (2), a pushing piece (8) is connected to the side wall of the rotor (6), a convex boss (7) is connected to the front end of the rotor, the convex boss (7) is provided with a protruding bar (17) which is arranged perpendicular to the axial direction of the convex boss (7), and a groove (16) used for containing the protruding bar (17) and the convex boss (7) is formed in a key (15).The mechanical unlocking device for the electromagnetic lock is high in safety level and high in 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...
