Anti-theft mechanical interlocking and side-locking additional lock
The invention discloses an anti-theft mechanical interlocking and side-locking additional lock. A back lock core and a front lock core of the anti-theft mechanical interlocking and side-locking additional lock are completely disconnected from each other; a sliding hole, a dedicated key hole and an invisible hole are formed in the front lock core; a connecting body is mounted inside the invisible hole; the connecting body is disconnected from the back lock core; a locking hole and a connecting hole are formed in the back lock core; a connecting tongue at the back end of the back lock core penetrates through a via hole, is connected with a linkage mechanism and is connected with a lock tongue; a locking head is arranged in front of a locking spring inside a locking socket hole; the locking head and an ejector post are mounted inside the locking hole; a sliding rod in front of the ejector post is mounted inside the sliding hole; an expanding end of an expanding sheet stretches into a locking slot to lock up the front lock core; a side-locking device and a rotary locking device lock up the front lock core. The anti-theft mechanical interlocking and side-locking additional lock integrates mechanical interlocking, visibility, and visible connection of the front lock core and the back lock core, so that a theft cannot open an interlocking device and cannot rotate the back lock core; even after interlocking and self-locking parts are violently damaged, only the front lock core can be rotated and the back lock core cannot be rotated, so that the anti-theft mechanical interlocking and side-locking additional lock achieves a complete anti-theft effect.
