LOCK CYLINDER AND LOCK
The present invention provides a lock cylinder and a lock, and belongs to the field of locks. The lock cylinder includes a base, a lock bolt, a cam, an energy storage member, a driving device, and a one-way locking mechanism. The lock bolt is movably provided on the base. The cam is rotatably provided on the base. The cam has a first position in which the lock bolt is prevented from retracting and a second position in which the lock bolt is allowed to retract. The energy storage member is connected between the driving device and the cam. While the lock bolt locks the cam, the driving device operates to cause the energy storage member to store an elastic force. While the lock bolt unlocks the cam, the elastic force drives the cam to rotate. The one-way locking mechanism is configured to restrict retraction of the lock bolt after the lock bolt extends and unlocks the cam located in the second position. After the lock bolt extends and unlocks the cam in the second position, the one-way locking mechanism restricts retraction of the lock bolt. Even if a lock beam applies thrust to the lock bolt during a process in which the lock beam is pulled outwards, the lock bolt may not retract to a position in which the lock bolt locks the cam, and the lock bolt always engages with a lock beam gap of the lock beam, thereby eliminating false locking.
