Adopt above-mentioned technical scheme, the utility model has the advantages of as follows:
1. after the utility model is matched with the nut for pre-tightening, the fastening surface of the gasket body is tightly attached to the workpiece, on one hand, the fastening surface of the gasket body is arranged to be an inclined surface, compared with the traditional gasket, the friction surface of the fastening surface is increased, thereby the friction force is increased, the fastening effect is improved, on the other hand, the acting force acting on the fastening surface generates component force along the inclined surface direction, and acts on the bolt to enable the axis of the bolt to incline, thereby forming self-locking in the whole circumferential direction, preventing the nut from loosening, and simultaneously, the workpiece acts on the fastening surface of the gasket body in a reverse way, so that the workpiece; the fastening surface of the washer body is an inclined surface, after pre-tightening, the axes of the washer body and the nut are not in the same straight line with the axis of the acted bolt, self-locking is formed in the 360-degree circumferential direction, and the anti-loosening effect is good.
2. The lower end of the central hole of the washer body is provided with a compensation hole, the matched nut acts on the bolt to enable the bolt to generate slight bending deformation after being pre-tightened, the arrangement of the compensation hole can compensate the bending of the bolt in size, the stress generated by the bending of the bolt and the washer body is reduced, the use strength of the bolt is improved, the arrangement of the compensation hole enables the washer body to adapt to the matching of the bolt after the bending deformation when the washer body is installed, and the proper elastic space is provided on the other hand, so that the application range of the washer body is enlarged.
3. The utility model discloses after the nut pretension, the auto-lock just can be realized to the inclined plane structure through packing ring body fastening face, reaches locking effect that moves, simple structure, the installation of being convenient for, the processing cost is low, easily promotes, and the practicality is strong.
