Lock cylinder with function of preventing lock from being violently unlocked
The invention relates to a lock cylinder with a function of preventing a lock from being violently unlocked. The lock cylinder is characterized in that one layer of lock cylinder shell is added outside an outer lock cylinder of a traditional tumbler lock, the outer lock cylinder cannot rotate in normal use, an inner lock cylinder is not directly connected with an unlocking part but is connected with the unlocking part through a clutch consisting of a transmission ring and a transmission shaft, and a violence sensor is further arranged in the lock cylinder. When a person tries to violently unlock the lock, the inner lock cylinder drives the outer lock cylinder to rotate together, and a slope between the outer lock cylinder and the violence sensor produces axial thrust so as to push the violence sensor to axially move. In this way, the clutch acts, the unlocking part cannot be continuously driven to rotate, and the inner lock cylinder and the outer lock cylinder can only idle and unlocking cannot be realized. When the inner lock cylinder and the outer lock cylinder return to original positions, the violence sensor and the transmission ring also return to original positions under the action of a reset spring.
