Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle lamp assembly bolts, and particularly relates to a rear combined vehicle lamp assembly bolt which can prevent thread bite. Background Art

[0002] The rear combination lights of a car, commonly also called taillights or rear taillights, are a group of lights installed at the rear of the car. They mainly serve the purpose of lighting and signal indication. They include rear width lights, brake lights, rear fog lights, rear turn lights, etc. The main function of the rear combination lights is to improve the visibility of the vehicle at night or in bad weather conditions, and to convey the vehicle's driving status, such as steering and braking, to other road users.

[0003] When assembling rear combination lights, mounting bolts are required to connect the rear combination lights to the automobile sheet metal parts. However, the threads of the existing rear combination light mounting bolts may engage with the threads of the nut when screwing in, thereby causing damage to the threads of the rear combination light mounting bolts and affecting the assembly and use of the rear combination lights. Therefore, we propose a rear combination light mounting bolt that prevents thread engagement. Utility Model Content
