Abstract

The invention discloses a vane-structured idling lock that comprises a lock body; the lock body comprises a front lock core and a rear lock core respectively with a latch clutch mechanism; the rear lock core is arranged with a latch pin runner and a latch pin in a slot; 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 arranged with a breach that is accordingly opened on the latch pin runner; the latch pin cam match with the breach. The invention summarizes characteristics of prior arts, and combines the advantages with the arc-shaped vane-structured lock, so as to guarantee more reasonable structure and broad application scope.

Description

Technical field [0001] The invention belongs to a mechanical lock, and relates to a blade structure lock head with a lock core capable of idling. Background technique [0002] At present, there is a lock cylinder with a lock cylinder clutch structure in which the lock cylinder can be idle (see Chinese Patent Application No. 200710034226.3). After the lock head adopts this lock cylinder clutch structure, the front lock cylinder can rotate 360 ​​degrees relative to the rear lock cylinder and the lock body when the lock is locked, so as to effectively prevent technical unlocking and twisting of the lock cylinder. This kind of lock still has limitations in structure and application range, and needs further improvement. Summary of the invention [0003] The purpose of the present invention is to provide an idling lock with a blade structure in view of the above situation. The lock head integrates the characteristics of the existing technology, has a more reasonable structure and a wi...
