Description

Technical Field

[0001] The utility model belongs to the field of automobile steering wheels, in particular to an automobile steering wheel lock. Background Art

[0002] As the number of cars increases, the number of theft cases is also gradually increasing, especially in urban areas. Therefore, car manufacturers and security equipment manufacturers have begun to develop various anti-theft measures to protect vehicles and car owners' property. Car steering wheel locks are an effective car anti-theft tool. Its working principle is to lock on the steering wheel and use the protruding part to prevent the steering wheel from turning, thereby preventing the car from being stolen. In order to improve the anti-theft performance of the vehicle, there are already a wide variety of car anti-theft locks on the market, which are mainly divided into electronic anti-theft locks and mechanical anti-theft locks. Electronic anti-theft locks are expensive and complicated to install, while mechanical anti-theft locks are relatively low in cost. For example, general steering wheel anti-theft locks mostly use the rotation of the restricted direction to achieve the purpose of locking.

[0003] Existing car steering wheel locks basically have a lock rod to fix or buckle the steering wheel. The lock rod is a metal object with high hardness and is difficult to damage, so the anti-theft performance is high. However, these anti-theft locks with lock rods cannot be stored and take up a lot of space in the car. They are hard and easily deformed by external impacts. They can only be replaced as a whole, which is costly. Utility Model Content
