Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, and particularly relates to an automotive fastener. Background Art

[0002] Automotive fasteners are mechanical parts that fasten various parts or components in an automobile into a whole, and play a crucial role in automobile manufacturing and maintenance. With the development and popularization of new energy vehicles, the quality and performance requirements for automotive fasteners are also getting higher and higher. In the manufacturing of new energy vehicles, for example, the connection between the battery pack and the vehicle frame puts forward higher requirements for the reliability and durability of automotive fasteners.

[0003] Currently, the research on automotive fasteners at home and abroad mainly focuses on aspects such as materials, structural design, and manufacturing processes. In terms of materials, characteristics such as high strength, corrosion resistance, and high temperature resistance are the current research focuses. In terms of structural design, how to improve the load-bearing capacity and anti-loosening performance of fasteners is also the focus of research. In terms of manufacturing processes, advanced processing technologies and surface treatment technologies provide support for improving the quality and performance of fasteners.

[0004] There are some technical problems in the field of existing automotive fasteners that need to be solved. For example, traditional anti-loosening methods often require damaging the fastener itself and cannot be reused, which brings inconvenience to maintenance and replacement. In addition, the anti-loosening performance of fasteners in some special environments is not good, and loosening is likely to occur, leading to potential safety hazards.

[0005] In view of the existing technical problems, the inventor has proposed improvements. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an automotive fastener with simple structure, convenient installation, and good fixing effect. To achieve the above-mentioned utility model purpose, an automotive fastener of the utility model includes:

[0007] A nut;

[0008] A screw rod integrally cold-forged with the nut, which is formed below the nut. Wherein, spiral threads are provided on the outer edge of the screw rod; and

[0009] A gasket, which is arranged below the nut and sleeved on the outside of the screw rod. Wherein, a through hole for the screw rod to pass through is provided in the middle of the gasket, an opening is formed on the main body of the gasket, and angles are formed on both sides of the opening, and the opening catches both sides of the thread. It can effectively fix automotive parts and improve the safety and stability of the whole vehicle.

[0010] Moreover, the gasket has a certain included angle. After being tightened in place, both ends of the gasket abut against the bottom of the nut and the outer surface of the workpiece, with simple structure, convenient installation, and not easy to loosen.

[0011] A further improvement of an automotive fastener of the present utility model lies in that the nut is a hexagonal nut.

[0012] A further improvement of an automotive fastener of the present utility model lies in that the thread of the screw rod is a self-tapping thread.

[0013] A further improvement of an automotive fastener of the present utility model lies in that the gasket is made of a metal material.

[0014] The beneficial effects of the present utility model are as follows:

[0015] An opening is formed on the gasket body, and angles are formed on both sides of the opening, and the opening catches both sides of the thread. It can effectively fix automotive parts and improve the safety and stability of the whole vehicle.

[0016] Moreover, the gasket has a certain included angle. After being tightened in place, both ends of the gasket abut against the bottom of the nut and the outer surface of the workpiece. The structure is simple, the installation is convenient, and it is not easy to loosen. BRIEF DESCRIPTION OF THE DRAWINGS
