Mechanical asynchronous interlocking spring-free additional antitheft lock

Abstract

The invention discloses a mechanical asynchronous interlocking spring-free additional antitheft lock. The rear lock cylinder and the front lock cylinder of the mechanical asynchronous interlocking spring-free additional antitheft lock are completely disconnected from each other; a sliding hole, a special key hole and a hiding hole are formed in the front lock cylinder; a connector is mounted in the hiding hole; the connector is disconnected from 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 goes through a via hole and is connected with a link gear and then connected with a spring bolt; a locking head is arranged in front of a locking spring in a locking bearing hole; the locking head and a jack-prop are mounted in the locking hole; a sliding rod in front of the jack-prop is mounted in the sliding hole; a slider is mounted in a sliding groove and a curved groove; the expansion end of an expansion piece extends into a locking groove to lock the front lock cylinder; the front lock cylinder is locked by a rotary locking device. The mechanical asynchronous interlocking spring-free additional antitheft lock is integrated with mechanical interlocking, hiding and connection hiding of the front and rear lock cylinders, and therefore, the interlocking device cannot be opened and the rear lock cylinder cannot be rotated by a theft; even though the interlocking and self-locking parts are damaged violently, only the front lock cylinder can be rotated and the rear lock cylinder cannot be rotated.

Description

technical field [0001] The invention relates to a mechanical asynchronous interlocking non-bomb additional anti-theft lock in the field of anti-theft locks. Background technique [0002] There are many kinds of anti-theft locks in use now, but basically all of them use the key to open the marble and then rotate to drive the deadbolt to open the anti-theft lock. It was the unlock king who easily opened the anti-theft lock. There are basically no anti-theft locks that thieves and unlocking kings cannot open. Contents of the invention [0003] The purpose of the present invention is to provide a kind of anti-theft lock that can't be opened by thieves and unlocking kings, which integrates asynchronous interlocking, self-locking and mechanical interlocking, high security, the manufacture of anti-theft locks without marbles and its method. [0004] In order to achieve the above object, the mechanical asynchronous interlocking non-bomb additional anti-theft lock of the present...
