Mechanical asynchronous side-locking additional burglar-proof lock

Abstract

The invention discloses a mechanical asynchronous side-locking additional burglar-proof lock. A rear lock cylinder and a front lock cylinder are completely separated, a connecting body is concealed in an invisible hole, and an expanding piece locks the front lock cylinder. A leading hole, a special key hole and the invisible hole are formed in the front lock cylinder, and the connecting body is arranged in the invisible hole and separated from the rear lock cylinder. A connecting hole is formed in the front of the rear lock cylinder, and a connecting tongue is fixed to the back of the rear lock cylinder and penetrates through a via hole. A sliding bar is arranged in front of a guiding spring in a sliding hole and installed in an extruding groove and the sliding hole, an extruding block is embedded into the part, in the extruding groove, of the sliding bar, the expanding end of the expanding piece locks the front lock cylinder in the extruding groove, and a side-locking device and a rotating locking device lock the front lock cylinder. The lock integrates invisible mechanical interlocking and invisible connection of the front lock cylinder and the rear lock cylinder, and therefore a burglar can not open an inner supporting locking part and rotate the rear lock cylinder at the same time; the burglar can only rotate the front lock cylinder even though damaging the inner supporting locking part, a rotating disc and a rotating corner in a violent manner, and the rear lock cylinder can not be rotated. Thus, a complete burglar-proof effect is achieved.
