[0022] This utility model provides, for example Figures 1-5 The rivet assembly shown includes a rivet body 1, an anti-loosening ring 2, and a rivet assembly part 3. The rivet assembly part 3 is provided with a rivet assembly hole 301 for screwing into the rivet body 1. An anti-loosening ring assembly groove 302 is provided at the end of the rivet assembly hole 301. During assembly, the anti-loosening ring 2 is fitted into the anti-loosening ring assembly groove 302. The rivet body 1 is connected to the rivet assembly hole 301 on the rivet assembly part 3, so that the rivet head end 101 of the rivet body 1 clamps and abuts against the anti-loosening ring 2.

[0023] Combination Figure 3 , Figure 4 and Figure 5 As shown, the anti-loosening ring 2 includes an upper anti-loosening ring 201 and a lower anti-loosening ring 202. An elastic deformation ring 203 is integrally formed between the upper anti-loosening ring 201 and the lower anti-loosening ring 202. The lower surface of the lower anti-loosening ring 202 is provided with an anti-rotation limiting toothed ring 2021.

During the tightening process of the rivet body 1, the self-locking toothed ring 1011 at the bottom of the rivet head end 101 and the self-locking limiting ring 2011 on the upper surface of the upper anti-loosening ring 201 can only rotate and mesh in one direction and cannot reverse, thereby effectively preventing the rivet body 1 from rotating and falling off in the opposite direction.

[0025] The elastic deformation ring 203 is an elastic sheet with a cross-section of "<". The elastic deformation ring 203 has 2-3 teeth. The tooth height of the anti-rotation limiting tooth ring 2021 is 1.5-2 mm, and the deformation of the elastic deformation ring 203 is greater than 2 mm.
