Additional tooth pushing mechanical anti-theft lock
The invention discloses an additional tooth pushing mechanical anti-theft lock. A rear lock cylinder and a front lock cylinder of the anti-theft lock are completely disconnected and are hidden in an invisible hole together with a connection body; a connection hole is formed in the front surface of the rear lock cylinder, and a connection tongue penetrating through a via hole is fixed on the rear surface of the rear lock cylinder; a sliding rod mounted in a sliding hole is arranged in front of a guide spring in the sliding hole; the sliding rod is mounted in an expansion slot and the sliding hole; a shifting fork in a sliding chute is fixed on the sliding rod through a connection pin; the expansion end of the expansion sheet is pressed against a lock-up slot to lock the front lock cylinder; a tooth pushing device and a connection lock-up device are used for locking the front lock cylinder. Inclined-hanging direct-pushing rotary type unlocking is adopted; invisible mechanical interlocking and invisible connection 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 the external expansion lock-up device and a locking column are damaged with savage measures, and burglary prevention can be completely and thoroughly achieved.
