Abstract

A vane structured idling lock comprises a lock body; the lock body comprises a front lock core and a rear lock core respectively arranged with a latch clutch mechanism; the latch clutch mechanism is composed of a side lock bar that can fit with a V-shaped slot on vanes inside a side lock bar slot on the front lock core; meanwhile, a slider is provided inside a slider runner communicating with the side lock bar slot; at least one of the slider and the side lock bar contacts with the other through a slope along the axial direction of the lock core; the rear lock core is arranged with a latch pin runner and a latch pin inside the groove; a latch pin resetting spring is arranged between the end wall and the latch pin inside the latch pin runner; the lock body tail is positioned with a sidestep to latch the rear lock core; the sidestep is opened with a breach corresponding with the latch pin runner; the latch pin can fit with the breach. The invention summarizes characteristics of prior arts, and combines the advantages with the vane-structured lock, so as to guarantee more reasonable structure and broad application scope.

Description

technical field [0001] The invention belongs to mechanical locks, and relates to a blade structure 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 blade-structured idle lock head for the above situation. The lock head combines the characteristics of the prior art, has a more reasonable structure and a wider appli...
