Document Type and Number:
WIPO Patent Application WO/2023/133680
Kind Code:
A1
Abstract:
Disclosed is an anti-knock lock, comprising a lock case, and a bolt, a stop block, a power device, a cam, a sliding rod, a first reset piece and a second reset piece which are arranged in the lock case. The lock case is provided with a lock hole. The middle of the bolt is rotationally connected to the lock case, one end of the bolt being in a telescopic fit at the lock hole. The middle of the stop block is rotationally connected to the lock case. The power device is in a driving connection to the cam and is used for driving the cam to rotate. The cam is arranged opposite to the sliding rod, the sliding rod moving along with rotation of the cam. The sliding rod is in a sliding fit with the lock case and points to the lock hole. The stop block rotates along with movement of the sliding rod so as to block or allow the rotation of the bolt. The first reset piece is used for providing an elastic force so as to enable the bolt to be reset to a locked state, in which one end of the bolt extends out of the lock hole. The second reset piece is used for providing an elastic force so as to enable the sliding rod to be reset to a locked state, in which the sliding rod drives the stop block to block the rotation of the bolt. The present invention, while having a knock-unlocking-prevention function, realizes a simplified structure and reduces cost.
