Anti-theft mechanical interlocking lock with toothed pusher
The invention discloses an anti-theft mechanical interlocking lock with a toothed pusher. A back lock cylinder is fully separated from a front lock cylinder; a sliding hole, a special key hole and a hiding hole are formed in the front lock cylinder; a connector is arranged in the hiding hole; the connector is separated from the back lock cylinder; a locking hole and a connecting hole are formed in the back lock cylinder; a connection bolt at the back end of the back lock cylinder is connected with a linkage mechanism after passing through the hole, and is connected with a lock bolt; a locking head is arranged in front of a locking spring in a locking support hole; the locking head and a support column are arranged in the locking hole; a slide bar in front of the top column is arranged in the sliding hole; the expansion end of an expansion sheet extends into a locking groove to lock the front lock cylinder; a toothed pushing device and a connection locking device are used for locking the front lock cylinder. Mechanical interlocking, hiding and connection hiding of the front and back lock cylinders are integrated, so that a thief cannot open an interlocking device or rotate the back lock cylinder; even though the interlocking and self-locking parts are damaged with brutal means, only the front lock cylinder can be rotated, but the back lock cylinder does not rotate, so that theft can be prevented completely.
