Problems solved by technology

However, if an incorrect key is inserted, when the user exerts more force, the lock cylinder will not be able to rotate relative to the lock body, thereby causing the lock body to bear a large torque, which will cause damage to the lock cylinder or the lock body.
That is, the ignition lock is twisted

Embodiment Construction

[0014] Examples, see Figure 1 to Figure 4 As shown: the anti-twist car ignition lock includes a lock body 10 arranged on the main body 100 of the car, and the lock body 10 is provided with a lock cylinder 11 that can rotate with the inserted key. Further speaking, the lock body 10 is pivotally connected to the main body 100 , and the lower end surface of the lock body 10 is provided with a connecting protrusion 12 . That is, the lock body 10 can rotate relative to the main body 100 . Simultaneously, the bottom of the lock body 10 is not rotatable but can be displaced up and down to be provided with a bearing seat 20, the bottom of the bearing seat 20 is provided with a compression spring 30, and the upper end surface of the bearing seat 20 is provided with the connecting projection 12. Matching connection groove 21. That is, under the action of the compression spring 30 , the bearing seat 20 pushes upward against the lock body 10 , so that the connecting protrusion 12 is in...

Abstract

The invention discloses a torsion-damage-preventing automobile ignition lock which comprises a lock body disposed on an automobile body. The lock body pivoted to the automobile body is provided with a lock cylinder inside. A connecting protrusion is disposed on the lower end face of the lock body. A bearing block is unrotationally disposed below the lock body. A compression spring is disposed on the lower portion of the bearing block. The upper end face of the bearing block is provided with a connecting groove matched with the connecting protrusion. After modification, the connecting protrusion and the connecting groove are trapezoidal. The torsion-damage-preventing automobile ignition lock has the advantage that torsion damage of the ignition lock can be avoided even when an incorrect key is inserted.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an anti-twisting auto ignition lock. Background technique [0002] Generally, an automobile ignition lock includes a lock body, a lock cylinder capable of rotating within a certain angle is arranged inside the lock body, and the lock body is non-rotatably fixed on the main body of the automobile. That is, the correct key is inserted into the lock cylinder, the lock cylinder is rotated, and the ignition of the car can be realized. However, if an incorrect key is inserted, the lock core will not be able to rotate relative to the lock body when the user exerts more force, thereby causing the lock body to bear a relatively large torque, thereby causing damage to the lock core or the lock body. That is, the ignition lock is twisted. Contents of the invention [0003] The purpose of the present invention is to provide an anti-twisting automobile ignition lock, which has the char...
