Abstract

The invention relates to a lock with a striking-opening-resistant clutch. The lock comprises a lock shell, the clutch accommodated in the lock shell and a drive device. The drive device is located on the side of the clutch. The clutch comprises an inner clutching block and an outer clutching block, wherein the inner clutching block and the outer clutching block can rotate relative to each other. The clutch is further provided with a clutching pin capable of controlling the inner clutching block and the outer clutching block to be connected or disconnected. The lock is characterized in that the lock further comprises an intermediate transmission piece arranged between the clutching pin and an output shaft of the drive device and provided with an arc-shaped part. The intermediate transmission piece is connected with the output shaft of the drive device as well as the clutching pin. The output shaft of the drive device or the clutching pin is slidably connected to the intermediate transmission piece along the arc-shaped part of the intermediate transmission part.

Description

technical field [0001] The invention relates to a lock, in particular to a lock with an anti-knock opening clutch. Background technique [0002] A lock is a device that can close the door leaf, so that illegal elements cannot enter the room at will. However, with the improvement of the non-technical opening ability of locks mastered by criminals, some locks can be easily opened by unconventional means. requirements. Electronic locks are more and more favored by modern people for their unique safety and convenience. In the current field of electronic locks, one of the means to improve its safety is to set a clutch on the transmission path between the door handle and the deadbolt, and the structure of the clutch currently exists in various forms. [0003] For example, the patent number of the existing technology is 201020607497.0, the application date is June 1, 2011, and the Chinese utility model patent named "Electronic Lock Clutch" discloses a lock clutch mechanism, incl...
