Description

Hub fastener with protective cover not easy to fall off

Technical Field

The utility model relates to a fastener technical field, specific theory relates to a wheel hub fastener that protective cover is difficult for droing.

Background

Fasteners are commonly used to connect multiple parts together. Typically, the fastener includes at least a threaded portion and one or more torquing surfaces thereon. The torquing surface is designed to receive the torque of a tool, such as a socket wrench or other wrench, which is used to tighten or loosen a fastener. Conventional fasteners, such as nuts, have internal threads and 6 torquing surfaces that are hexagonal about the internal threads, however, other fasteners have external threads, such as bolts and screws, and the fasteners may have a different number of torquing surfaces than those described above.

Decorative wheel fasteners have become an important component of wheel aesthetics in automotive styling. In particular, many automotive consumers are attracted to the aesthetics of the wheels of an automobile because this is often a unique part of the automobile. As a result, automobiles are more common because the wheel nuts form a highly visible pattern around the center of the wheel, which becomes an integral part of the wheel aesthetics. However, automotive wheel nuts are very susceptible to corrosion, as the wheels of vehicles are often subjected to wet and salty environments. Of course, corrosion on the visible surface of the wheel nut greatly detracts from the aesthetics of the wheel and vehicle.

One method of dealing with the aesthetic appeal of wheel nuts with great success is stainless steel capped wheel nuts. In this solution, the nut body is covered with a stainless steel cap. Stainless steel capped wheel nuts have been able to meet most of the demands for aesthetically pleasing wheel nuts due to their corrosion resistance, durability, and visual appeal. An additional advantage of the stainless steel capped wheel nut is that the color of the stainless steel, sparkling silver, generally matches the color of most automobile wheels.

Chinese patent document CN107387530A discloses a fastener for a vehicle wheel, comprising a fastener body including a thread around an axis of the fastener body; a top portion having a plurality of torsional surfaces disposed about the top portion; a bottom portion having a circular cross-section located below the top portion; wherein the bottom portion extends radially beyond the top portion and forms a shelf where the top portion meets the bottom portion; a plurality of protrusions are disposed on the shelf, wherein the plurality of protrusions extend radially outward beyond the circular cross-section of the bottom portion; a shield cover having a wall, the shield cover being disposed on the top portion of the fastener body and partially on the bottom portion of the fastener body; a portion of the shield cover disposed on the bottom portion includes a double wall, wherein the double wall portion of the shield cover is located adjacent to the plurality of projections.

In the design, the protective cover is internally manufactured into a shape in interference fit with the nut, then the nut is inserted into the protective cover, the protective cover and the nut are kept connected by virtue of friction force, the connection is not firm enough, and the protective cover can loosen or even fall off after long-term use.
