Mechanical asynchronous interlocking theft-proof lock with side lock
The invention discloses a mechanical asynchronous interlocking theft-proof lock with a side lock. A rear lock core is completely disconnected with a front lock core, a connector is arranged in an invisible hole in the front lock core, and the connector is disconnected with the rear lock core; a lock hole and a connecting hole are formed in the rear lock core, a connecting tongue at the rear end of the rear lock core is connected with a linkage mechanism after passing through a hole, and then the connecting tongue is connected with a lock tongue; a slide bar is arranged at the front of the lock spring, the slide bar is arranged in an expanding groove and a slide hole, an expanding sheet is propped against an arc-shaped surface or an inclined plane in a lock groove, a shifting fork is arranged at a thrust hole in the slide bar and fixed on the slide bar through a connecting pin, a propping spring is propped against the fork end of the shifting fork in a slide groove, and a side lock device and a connection lock device lock the front lock core. The mechanical asynchronous interlocking theft-proof lock with the side lock integrates mechanical interlocking, invisibility and front and rear lock core connecting invisibility so that a theft cannot open an interlocking device or rotate the rear lock core; even if interlocking and self-locking parts are damaged in a barbaric way, the thief can only rotate the front lock core, the rear lock core cannot be rotated, and the complete theft-proof effect is realized.
