[0026] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
[0027] Please refer to Figures 1-4 The self-gasket automobile nut comprises a nut body 1 and a gasket body 2, the gasket body 2 is arranged below the nut body 1, and further comprises:
[0028] The gasket body 2 is further provided below with a plurality of groups of fins 3;
[0029] The insertion assembly comprises a guide block 4 and a friction ring 5, the nut body 1 is provided with a threaded hole in the center, the guide block 4 is conical with the upper part being larger than the lower part, the guide block 4 is provided with a through hole in the center which is matched with the threaded hole, the maximum outer diameter of the guide block 4 is smaller than the outer diameter of the gasket body 2, the fins 3 are arranged on the circumferential side of the guide block 4, and the guide block 4 is further sleeved with the friction ring 5;
[0030] When assembling parts, the outer diameter of the part guide hole is larger than the bolt but smaller than the nut, at this time, the nut is first aligned with the guide hole. The guide block 4 is conical with the upper part being larger than the lower part, can be smoothly inserted into the guide hole, and the bolt is guided to accurately enter the threaded hole in the center of the nut body 1 by using the conical structure, so that the positioning error of the nut in the initial contact is avoided. With the screwing of the bolt, the friction ring 5 sleeved on the guide block 4 is in contact with the bolt, the friction between the nut and the bolt is increased, and the connection is more stable;
[0031] The fins 3 arranged below the gasket body 2 increase the friction between the nut and the connected parts, the fins 3 are tightly attached to the surface of the connected parts while the guide block 4 guides the bolt, so that the nut is prevented from being knocked off during installation. When the nut is subjected to external forces such as vibration during the operation of the automobile, the fins 3 and the friction ring 5 work together to improve the stability of the nut during the working process and ensure the reliable connection of the automobile parts;
[0032] The cylindrical sleeve 6 and the conical sleeve 7 of the protection assembly wrap the nut body 1 and the gasket body 2 respectively. The first cavity in the cylindrical sleeve 6 is matched with the nut body 1, the second cavity in the conical sleeve 7 is matched with the gasket, and the first cavity and the second cavity are through. The protection assembly is elastic and can tightly attach to the nut and the gasket, preventing impurities such as dust and moisture from the outside from entering, avoiding corrosion of the nut and the gasket, and prolonging the service life.
[0033] The outer side of the nut body 1 is a regular hexagon, facilitating tightening or loosening operation by using wrenches and the like. The arc-shaped clamping blocks 8 arranged on the outer side edge of the nut body 1 are matched with the clamping grooves in the first cavity. When installing the protection assembly, the cylindrical sleeve 6 of the protection assembly is aligned with the nut body 1, the clamping blocks 8 are arc-shaped, the clamping blocks 8 are clamped into the clamping grooves, and the installation is completed; when disassembling, the clamping blocks 8 are slightly forced to be separated from the clamping grooves, and the protection assembly can be removed, facilitating inspection, replacement and the like of the nut and the gasket.
[0034] The rounded 9 arranged on the upper edge of the nut body 1 can avoid scratching the hands of the operator during operation, improving the use experience. The friction pad 10 arranged below the conical sleeve 7 has a bottom wall flush with the bottom wall of the fin 3, and the friction pad 10 further enhances the friction between the nut and the connected component during installation and use, improving the overall stability.
[0035] In order to ensure the stability of use, another embodiment is further provided, the port of the cylindrical sleeve 6 can be provided with a notch, since the protection assembly has elasticity, the through bolt can be interference fit with the cylindrical sleeve 6, and the protection assembly further abuts against the nut body 1 with the gasket body 2. It should be noted that if the bolt penetrates the protection assembly, an external force needs to be applied to the protection assembly during penetration to ensure that the protection assembly is not lifted up, and after the bolt penetrates the protection assembly, the friction pad 10 of the protection assembly can stably adhere to the object, providing good protection for the nut body 1 with the gasket body 2.
