Technical Field

The invention relates to the technical field of locks, in particular to a multifunctional rotating piece, an electronic unlocking mechanism and an anti-misoperation electric control lock.

Background

At present, an electric control lock generally uses a locking hook and a locking bolt to cooperate for locking and unlocking, and the locking bolt is controlled to move through an electric drive element. During unlocking, the card reader is required to send an unlocking instruction to the electric control lock, and the purpose of unlocking is achieved by controlling the movement of the lock bolt. In order to prevent the lock bolt from moving, it is common practice to provide a spring between the lock bolt and the lock body, so as to prevent the lock bolt from moving by itself. And when the electric control lock is locked after being unlocked, the spring can provide elastic force for the lock bolt, so that the lock bolt moves towards the lock hook and is clamped with the lock hook, and automatic locking is realized.

Although the above electric control lock can utilize the elasticity of the spring to ensure that the lock bolt can not move by itself within a certain limit, the following problems still exist: when the force provided by the external vibration to the lock bolt is just the moving direction of the lock bolt during unlocking and is greater than the elastic force of the spring, the lock bolt can move under the action of the external force, and the lock bolt is unlocked mistakenly.
