Title:
LOCK CYLINDER AND LOCK
Document Type and Number:
WIPO Patent Application WO/2021/169180
Kind Code:
A1
Abstract:
The present application provides a lock cylinder and a lock, pertaining to the field of locks. The lock cylinder comprises a base, a lock tongue, a cam, an energy storage member, a driving device, and a one-way locking mechanism. The lock tongue is movably provided on the base. The cam is rotatably provided on the base. The cam has a first position in which the lock tongue is prevented from retracting and a second position in which the lock tongue is allowed to retract. The energy storage member is connected between the driving device and the cam. When the lock tongue locks the cam, the driving device operates to cause the energy storage member to store elastic force. When the lock tongue unlocks the cam, the elastic force drives the cam to rotate. The one-way locking mechanism is used to restrict retraction of the lock tongue after the lock tongue extends and unlocks the cam located in the second position. After the lock tongue extends and unlocks the cam in the second position, the one-way locking mechanism restricts retraction of the lock tongue. Even if a lock beam applies thrust to the lock tongue during a process in which the lock beam is pulled outwards, the lock tongue cannot retract to a position in which the lock tongue locks the cam, and the lock tongue always engages with a lock beam gap of the lock beam, thereby eliminating false locking.
