AI Technical Summary
Existing automotive chassis flange nuts are prone to scratching the contact surface during disassembly, resulting in uneven friction distribution, increasing the difficulty of operation and potentially damaging the nuts and tools. Furthermore, a greater torque is required to achieve the desired tightening effect.
A new automotive chassis flange nut was designed. It uses a second anti-slip texture on the fixing plate to contact the chassis surface, and the wave structure of the gasket increases the friction to avoid rotational friction. Combined with the right-hand thread of the nut body and the plastic anti-slip ring, it ensures that the fastening effect is not affected.
It achieves the goal of not damaging the chassis surface during disassembly while maintaining the same tightening effect under the same torque, reducing the difficulty of operation and the risk of damage, and improving service life and safety.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive flange nuts, and more specifically, to an automotive chassis flange nut. Background Technology
[0002] A flange nut is a type of nut that plays a crucial role in numerous mechanical connection scenarios. Its distinguishing feature is a wide flange at one end, which increases the contact area between the nut and the connected component. Automotive chassis flange nuts are specifically designed for use in automotive chassis. The automotive chassis must bear the weight of the vehicle itself, passengers, and cargo, while also withstanding impacts and vibrations from the road surface. Under these complex and demanding conditions, automotive chassis flange nuts are extremely important for ensuring the secure connection of all chassis components. They ensure a tight connection between chassis parts, providing a solid foundation for the safety and stability of the vehicle during operation. Their quality and reliability directly affect the proper functioning of the automotive chassis structure and are a vital factor in ensuring the overall safety performance of the vehicle.
[0003] To enhance connectivity, flange nuts often feature anti-slip grooves on the flange surface. While this design effectively strengthens the connection, it also introduces significant drawbacks. When disassembly is required, these grooves can cause circumferential scratches on the contact surface with the flange. This is because the grooves move relative to the contact surface during disassembly, generating friction and disrupting the originally smooth contact surface. Furthermore, when tightening again, the scratches on the contact surface cause uneven friction distribution, requiring a greater torque to achieve the same tightening force as the initial installation. This not only increases the difficulty of operation but can also damage the nut, connected components, and related tools due to excessive torque.
[0004] How to design a car chassis flange nut to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides an automotive chassis flange nut, which aims to improve the problems mentioned in the background.

The gasket is wavy and located inside the circular groove. The outer side wall of the gasket is in contact with both the first anti-slip texture and the inner side wall of the circular groove.
[0008] Preferably, the inner wall of the nut body is provided with a thread, and the thread is a right-hand thread.
[0009] Preferably, the anti-slip ring is made of plastic and is located between the fixing ring and the nut body.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Example, refer to Figures 1-5A type of automotive chassis flange nut includes a nut body 1 and a flange plate 2. A fixing ring 4 is fixedly connected to the top of the nut body 1, and an anti-slip ring 5 is fixedly connected to the inner side wall of the fixing ring 4. A fixing ring 6 is fitted on the flange plate 2, and a gasket 7 is provided on the inner side of the fixing ring 6. A first groove 12 is provided on the outer side wall of the flange plate 2, and a plurality of second grooves 11 are provided below the first groove 12. The first groove 12 and the second grooves 11 are connected. A plurality of bosses 16 are provided on the inner side wall of the flange plate 2. A fixing piece 15 is fixedly connected to the fixing ring 6, and a first anti-slip texture 14 is provided on the inner side wall of the fixing piece 15. A circular groove 17 is opened at the bottom of the flange plate 2, and a locking point 18 is provided inside the circular groove 17. The locking point 18 is evenly distributed in the circular groove 17. The gasket 7 is wavy and located inside the circular groove 17. The outer side wall of the gasket 7 is in contact with both the first anti-slip texture 14 and the inner side wall of the circular groove 17.
[0024] The inner wall of the nut body 1 is provided with a thread 3, which is a right-hand thread. The anti-slip ring 5 is made of plastic and is located between the fixing ring 4 and the nut body 1. The nut body 1 is hexagonal in shape and is integrated with the flange 2. The flange 2 and the fixing ring 4 are located on both sides of the nut body 1. The first groove 12 is circular. Multiple second grooves 11 are evenly distributed on the outer wall of the flange 2. The number of bosses 16 is the same as the number of second grooves 11 and their positions correspond. The bosses 16 and the second grooves 11 are interference-fitted. The bosses 16 slide inside the first groove 12. The bottom of the fixing plate 15 is provided with a second anti-slip texture 19, which is serrated.
[0025] The working principle of this type of automotive chassis flange nut is as follows: The flange nut is installed on the bolts of the automotive chassis. By rotating the nut body 1 with a tool, the flange nut moves towards the chassis, thus fixing it in place. During this process, when the second anti-slip groove 19 on the fixing plate 15 first contacts the chassis surface, the friction between the fixing plate 15 and the chassis surface increases due to the presence of the second anti-slip groove 19. This causes the flange plate 2 to slide relative to the fixing plate 15, pressing the fixing plate 15 tightly against the chassis surface. Simultaneously, the force exerted by the flange plate 2 on the fixing plate 15 also acts on the gasket 7. Because the gasket 7 is corrugated, when the gasket 7 is subjected to force, its horizontal... As the surface area of the gasket increases, the friction between the outer wall of the gasket 7 and the inner wall of the first anti-slip texture 14 and the circular groove 17 also increases, since the outer wall of the gasket 7 is in contact with both the first anti-slip texture 14 and the inner wall of the circular groove 17. This keeps the gasket 7, the fixing piece 15, and the flange piece 2 in a fixed state, thus completing the fixing of the flange nut. During the installation of this flange nut, the second anti-slip texture 19 on the fixing piece 15 does not rotate and rub against the chassis surface. The second anti-slip texture 19 will not cause circumferential damage to the chassis surface. Therefore, when disassembling and reinstalling this flange nut, applying the same torque to this flange nut will still achieve the same tightening effect.
[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
