Description

Technical Field

[0001] The utility model relates to the technical field of automobile bumpers, in particular to a plastic fastener for an automobile bumper. Background Art

[0002] The latest national standard of my country, "Terms and Definitions of Automobile and Trailer Types" (GB / T3730.1-2001), defines automobiles as follows: non-track-borne vehicles driven by power and having four or more wheels, mainly used for: carrying people and goods; towing vehicles carrying people and goods; special purposes. Tires are one of the important parts of automobiles. They are in direct contact with the road surface and work together with the automobile suspension to mitigate the impact of the automobile when driving, ensuring good ride comfort and driving smoothness; ensuring good adhesion between the wheels and the road surface, improving the traction and braking performance of the automobile. The wheel hub is the rotating part of the wheel core connected to the inner profile of the tire through the column, that is, the metal part on the shaft that supports the center of the tire, also called the wheel rim, steel rim, wheel, tire bell. There are many types of wheel hubs according to diameter, width, molding method and material. In the past, the most common wheel hub bearings for cars were single-row tapered roller or ball bearings used in pairs. With the development of technology, car hub units have been widely used in cars. The scope and amount of use of wheel hub bearing units are increasing, and they have developed to the third generation.

[0003] However, the existing automobile bumper plastic fasteners do not have the function of adjustment and fixing, so they can only be installed at the fixing holes, which makes it impossible to quickly fix the automobile bumper plastic fasteners, reducing the fixing efficiency of the automobile bumper plastic fasteners. Therefore, we propose a automobile bumper plastic fastener. Utility Model Content
