Door plate locking device
The invention discloses a door plate locking device used on a full-automatic safety type cover plate. The door plate locking device is characterized in that the door plate locking device comprises a lock cylinder sleeve, a lock cylinder sleeve fixing plate, a lock cylinder sleeve end cover, a lock cylinder and a telescopic movement device; the lock cylinder sleeve is installed on the lock cylinder sleeve fixing plate; the lock cylinder sleeve end cover is installed at the rear end of the lock cylinder sleeve; the lock cylinder penetrates the lock cylinder sleeve and can move forwards and backwards in the axial direction; the rear end of the lock cylinder is connected with the telescopic movement device; and the lock cylinder can be driven by the telescopic movement device to move forwards and backwards so that locking and unlocking can be achieved. The door plate locking device is reasonable in structural design, a door plate can be locked, and therefore the door plate cannot be opened by external force, and safety performance is improved.
