Ring lock capable of preventing brute-force unlocking

Abstract

The present utility model provides a ring lock capable of preventing brute-force unlocking, comprising a lock ring part, a lock body, a lock gate, and a driving mechanism for driving the lock gate to fit into the lock ring. The lock body is internally provided with space for the lock gate to linearly reciprocate, and further comprises a rotating member that is connected between the driving mechanism and the lock gate and drives the lock gate to linearly reciprocate. The rotating member is rotatably arranged in the lock body, and one end of the rotating member is in transmission fit with the driving mechanism. The rotating member is provided with an eccentric transmission part which is eccentrically arranged, and the eccentric transmission part is in transmission fit with the lock gate. During rotation, the eccentric transmission part pushes the lock gate to move linearly. A torsion spring that keeps driving the lock gate to be in a locked state for a long time is provided between the rotating member and the lock body. According to the present utility model, opening and locking of the lock gate are cleverly achieved by means of the rotation of the rotating member, and it would be difficult to cause the rotating member to rotate by smashing the lock with brute force. Moreover, the parts such as the lock gate, the rotating member, and the torsion spring are farther away from the end of the lock body and are less affected. Hence, the capability to prevent brute-force unlocking is greatly enhanced, and the product quality is improved.
