Mechanically asynchronous interlocking and tooth-pushing additional anti-theft lock
The invention discloses a mechanically asynchronous interlocking and tooth-pushing additional anti-theft lock. A rear lock cylinder of the mechanically asynchronous interlocking and tooth-pushing additional anti-theft lock is completely disconnected from a front lock cylinder; a sliding hole, a special key hole and an invisible hole are formed inside the front lock cylinder, and a connector is mounted in the invisible hole and is disconnected from the rear lock cylinder; a locking hole and a connection hole are formed inside the rear lock cylinder, and a connection tongue at the rear end of the rear lock cylinder passes through a through hole, is connected with a linkage mechanism 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 an ejection column are mounted in a locking hole, the sliding rod in front of the ejection column is mounted in the sliding hole, and sliding blocks are mounted in a sliding groove and a turning groove; the expansion end of an expansion sheet extends into a locking groove and locks the front lock cylinder, and a tooth-pushing device and a rotary locking device lock the front lock cylinder. The mechanically asynchronous interlocking and tooth-pushing additional anti-theft lock integrates the functions of mechanical interlocking, invisibility and connection invisibility of the front lock cylinder and the rear lock cylinder, so that a thief cannot open an interlocking device and cannot rotate the rear lock cylinder; even if interlocking and self-locking parts are damaged in a barbarous way, only the front lock cylinder can be rotated while the rear lock cylinder cannot be rotated.
