Mechanical asynchronous tooth-pushing additional interlocking anti-theft lock
The invention discloses a mechanical asynchronous tooth-pushing additional interlocking anti-theft lock. A rear lock cylinder of the mechanical asynchronous tooth-pushing additional interlocking anti-theft lock is completely disconnected with a front lock cylinder, a connecting body is installed in an invisible hole formed in the front lock cylinder and is disconnected with the rear lock cylinder. A locking hole and a connecting hole are formed in the rear lock cylinder, and a connecting tongue at the rear end of the rear lock cylinder penetrates through a via hole to be connected with a linkage mechanism and then is connected with a locking tongue. A sliding rod in front of a locking spring 10 is installed in an expansion groove and a sliding hole, an expansion piece abuts against an arc-shaped plane or an oblique plane in a locking groove, a shifting fork is arranged at the position of a thrust hole formed in the sliding rod and is fixed to the sliding rod through a connecting pin, an ejection spring ejects the fork end of a shifting fork in the sliding groove, and a tooth-pushing device and a connecting-locking device lock the front lock cylinder. The mechanical asynchronous tooth-pushing additional interlocking anti-theft lock integrates mechanical interlocking, invisibility and invisible connection between the front lock cylinder and the rear lock cylinder and enables a theft to be incapable of unlocking an interlocking device and turning the rear lock cylinder. Even if interlocking and self-locking portions are damaged by adopting a savage means, the theft can only turn the front lock cylinder, and the rear lock cylinder cannot be turned, so that thorough thievery prevention can be achieved.
