Interlocking mechanical gear-pushing additional anti-theft lock
The invention discloses an interlocking mechanical gear-pushing additional anti-theft lock. A rear lock cylinder of the anti-theft lock is completely disconnected with a front lock cylinder and a connector; a sliding rod is arranged in a sliding hole in the front lock cylinder, the connector is mounted in an invisible hole in the front lock cylinder, and an extrusion block is fixed on the sliding rod; a connecting tongue at the rear end of the rear lock cylinder is connected with a linkage mechanism after penetrating through a via hole, and then is connected with a lock tongue; a locking head is arranged in front of a locking spring in a locking bearing hole, the locking head and a top column are mounted in the locking hole, and the sliding rod in front of the top column is mounted in an extrusion groove and the sliding hole; the expansion end of an expansion piece stretches into the extrusion groove to lock the front lock cylinder, and the front lock cylinder is locked by a gear pushing device and a rotating locking device. The anti-theft lock integrates mechanical interlocking, invisibility and connecting invisibility of the front lock cylinder and the rear lock cylinder, so that a thief is incapable of unlocking an interlocking device or rotating the rear lock cylinder, only the front lock cylinder can rotate but the rear lock cylinder cannot rotate even if an interlocking part and a self-locking part are damaged by using brutal methods, and the prevention of burglary can be completely and thoroughly realized.
