Abstract
An anti-unlocked mechanism comprises a transmission gear, a sliding rod, a locking member and a first elastic member. The transmission gear includes an arc surface. An end of the sliding rod contacts the deadbolt of the lock body. The sliding rod is provided with a fixed stopper and a second elastic member. When the deadbolt is retracted, the sliding rod moves with the deadbolt against the elastic force of the second elastic member. When the deadbolt extends, the locking member moves with the sliding rod to block the rotation of the rotating part. The first elastic member comprises first and second protrusions. The second protrusion will not hinder the fixed stopper of the slide rod unless the first protrusion contacts with the circular arc surface, which will block the movement of the locking member to block rotation of the rotating part.
