Mechanical asynchronous and additional tooth pushing interlocking anti-theft lock
The invention discloses a mechanical asynchronous and additional tooth pushing interlocking anti-theft lock. A rear lock cylinder is completely disconnected from a front lock cylinder of the anti-theft lock, and a connection body is mounted in an invisible hole in the front lock cylinder and disconnected from the rear lock cylinder; a lock-up hole and a connection hole are formed in the rear lock cylinder; a connection tongue at the rear end of the rear lock cylinder penetrates through a via hole and is connected with a linkage mechanism and then a spring bolt; a sliding rod arranged on the front surface of a lock-up spring is mounted in an expansion slot and a sliding hole; an expansion sheet presses an arc-shaped surface or a slope in the lock-up slot; a shifting fork is arranged in a thrust hole in the sliding rod and fixed on the sliding rod through a connection pin; a pressing spring presses the fork end of the shifting fork in a sliding chute; a tooth pushing device and a connection lock-up device lock the front lock cylinder deadly. Invisible mechanical interlocking and invisible connection between the front lock cylinder and the rear lock cylinder are integrated, so that a thief can neither open an external expansion lock-up device nor rotate the rear lock cylinder and can only rotate the front lock cylinder instead of the rear lock cylinder even if an interlocking part and a self-locking part are damaged with savage measures, and burglary prevention can be completely and thoroughly achieved.
