Mechanical unlocking device for electromagnetic lock
The invention discloses a mechanical unlocking device for an electromagnetic lock, and belongs to the field of components of electromagnetic locks for high-voltage switch equipment. The mechanical unlocking device is characterized by comprising a lock casing, a lock cover, a lock catch, an L-shaped lock tongue, an electromagnet, an electromagnet lock column, a pushing column, a pressing spring and electronic key unlocking holes, wherein the L-shaped lock tongue is matched with the lock cover for opening and closing of the lock cover, the upper end of the pushing column is coupled to the lower part of the L-shaped lock tongue and matched with the lower end of the electromagnet lock column, and the pressing spring is connected to the electromagnet lock column in a sleeving manner; the mechanical unlocking device is characterized by further comprising a mechanical unlocking hole, a mechanical lock core, an unlocking drawing piece and a mechanical unlocking key, wherein the mechanical unlocking hole is positioned in the lock cover, the mechanical lock core is matched with the mechanical unlocking hole and is arranged in the mechanical unlocking hole, the unlocking drawing piece is coupled to the top end of the mechanical lock core, the head part of the unlocking drawing piece is in contact with the upper end of the L-shaped lock tongue in a matching manner, and the upper end of the lock tongue withdraws from the lock catch. Probation proves that compared with a conventional electromagnetic lock without the mechanical unlocking device, electromagnetic lock with the mechanical unlocking device can be unlocked by adopting the mechanical unlocking key when the electronic key is in fault, so that requirements of operating or maintaining the electromagnetic lock after the electromagnetic lock is unlocked are met.
