Abstract

The invention discloses an idling lock that comprises a lock body, a front lock core and a rear lock core inside the lock body. The front lock core is composed of two lines of side lock bars matching with V-shaped slots on lock core bullets, and slider runners that respectively communicate with two side lock bar slots; sliders are mounted inside the slider runners; between the sliders and the side lock bars, at least one adopts an oblique plane to contact with the other along the lock core shaft; the rear lock core comprises latch pin runners and latch pins inside the runners; latch pin resetting springs are arranged between the end wall and the latch pins inside the latch pin runner; the tail of the lock body is positioned with a sidestep to lock the rear lock core; on the sidestep, a breach is opened at a corresponding position to the latch pin runner; the latch pin can be fitted with the breach. The invention summarizes characteristics in prior arts, and integrates the idling lock with prior double-line bullet locks; therefore, the invented structure can be more reasonable and application scope can be expanded.

Description

technical field [0001] The invention belongs to mechanical locks, and relates to a lock head with a lock core that can rotate idly. Background technique [0002] At present, there is a lock cylinder clutch structure in which the lock head adopts a lock cylinder that can rotate idly (see Chinese patent application No. 200710034226.3). After the lock head adopts this lock cylinder clutch structure, it can realize the 360-degree idling of the front lock cylinder relative to the rear lock cylinder and the lock body when locking, so as to effectively prevent technical unlocking and prying of the lock cylinder. This lock still has limitations in structure and application range, and needs to be further improved. Contents of the invention [0003] The object of the present invention is to provide a kind of idle lock cylinder aiming at the above situation. The lock head combines the characteristics of the prior art, has a more reasonable structure and a wider application range. ...
