[0021] The present invention will be further described in detail below in conjunction with the drawings:
[0022] A locking pin assembly includes a locking ring 1 and a riveting nut 2; the riveting nut 2 is provided with a locking ring 1.
[0023] The locking ring 1 is composed of a locking ring end surface I18 of the supporting pin connection surface, an outer cylindrical surface 19 of the locking ring, a locking ring end surface II20 and an inner cylindrical surface 21 of the locking ring. The choice of material has lubricating effect, good wear resistance, and good sealing performance. It plays a role of self-lubrication in the assembly process, provides self-locking torque through the extrusion deformation of the external thread, and achieves the sealing effect at the same time. It integrates self-lubrication, sealing and locking integrated design. This is one of the keys of the present invention.
[0024] The riveting nut 2 includes nut cone surface 3, small inclined surface 4...
