Problems solved by technology

At the same time, the traditional bolts have disc gaskets or other gaskets with elastic deformation effect between the bolts and the mounting table to achieve the effect of locking between the nut and the table, but this way is between the nut and the installation. The anti-loosening effect is not optimal due to the force formed on the table, and how to improve the corrosion resistance of the bolts is also an existing problem

Embodiment Construction

[0028] refer to Figure 1 to Figure 2 The embodiment of the anti-loosening bolt for automobiles and the processing method thereof of the present invention will be further described.

[0029] For ease of description, if spatially relative terms such as "upper", "lower", "left", and "right" are used in the embodiments, they are used to describe the relative relationship between one element or feature shown in the figure and another element or feature Relationship. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other ori...

Abstract

The invention discloses an anti-loosening bolt for automobiles and a processing method thereof, and aims to provide an anti-loosening bolt for automobiles with good anti-loosening effect, simple structure and good corrosion resistance. It includes two parts: the nut part and the anti-loosening part. When the bolts and nuts are tightened, the locking part included in the anti-loosening part is matched with the through hole, arranged on the locking part and suitable for the inner step ring groove The matching outer step ring groove and the elastic ring arranged between the locking piece and the lock column. The lock column is provided with a ring groove matching the elastic ring. After the nut is tightened, because the locking piece and the nut form an inner, The buckle effect of the outer step structure, and because of the elastic ring arranged between the locking member and the lock cylinder, when the elastic ring is stressed, the elastic ring has elastic potential energy, forming a reverse force to ensure that the lock cylinder and the nut The screw threads between them are seized, and the invention is applicable to the technical field of fasteners for automobiles.

Description

technical field [0001] The invention relates to the technical field of fasteners for automobiles, more specifically, to an anti-loosening bolt for automobiles and a processing method thereof. Background technique [0002] Automotive bolts, especially chassis bolts, are subject to relatively large vibrations, and are also the places most likely to come into contact with moisture and other impurities, which are prone to oxidation and reduce their service life. [0003] At present, the anti-loosening bolts for automobiles on the market include a lock head and a lock cylinder. The lock head and the lock cylinder are integrally formed. The outer surface of the lock cylinder is formed with external threads. Shoulder, positioning shaft shoulder is provided with notch. At the same time, the traditional bolts have disc gaskets or other gaskets with elastic deformation effect between the bolts and the mounting table to achieve the effect of locking between the nut and the table, but ...
