Interlocking and gear pushing mechanical anti-theft lock
The invention discloses an interlocking and gear pushing mechanical anti-theft lock. A rear lock cylinder of the interlocking and gear pushing mechanical anti-theft lock is completely separated from a front lock cylinder of the interlocking and gear pushing mechanical anti-theft lock. A connection body of the interlocking and gear pushing mechanical anti-theft lock is hidden in a hidden hole. The front lock cylinder is locked through an expansion piece. A corner groove, a specially-matched key hole and the hidden hole are formed in the front lock cylinder. The connection body is arranged in the hidden hole and is separated from the rear lock cylinder. A connection hole is formed in the front face of the rear lock cylinder. A connection spring bolt is fixed to the rear face of the rear lock cylinder and penetrates through a passing hole. A slide block is installed in a slide groove and the corner groove. The slide block and a slide and push spring are arranged in the slide groove. The front lock cylinder is locked in a lock groove through the expansion end of the expansion piece. The front lock cylinder is locked through a gear pushing device and a connection locking device. The mechanical interlocking, hiding and the connection and hiding of the front lock cylinder and the rear lock cylinder are integrated, and the situation that a thief opens an inner supporting and locking part and rotates the rear lock cylinder at the same time can not happen; the thief can only rotate the front lock cylinder but can not rotate the rear lock cylinder even after the inner supporting and locking part and the connection body are damaged through barbaric means, and the complete and thorough thievery prevention can be achieved.
