Example Embodiment

[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...

Abstract

A locking pin assembly comprises a locking ring and a riveting nut. The locking ring is arranged in the riveting nut. The locking pin assembly is another important member in the field of self-locking connecting nut connecting assemblies. Due to the technical scheme, integrated design of integrating self lubricating, sealing and locking is adopted. The locking pin assembly is reliable in performance, simple in structure, low in cost and convenient to use and maintain.

Description

technical field [0001] The invention relates to a riveting and self-locking nut assembly, which is particularly suitable for a riveting and self-locking nut assembly which needs to be sealed and is connected with a self-locking and anti-dropping unit. Background technique [0002] At present, in the design of mechanical parts in the high-tech field, high-end fasteners with multi-functionality, small size and high reliability have high technical requirements, complex structures, difficult processes and expensive prices. In modern mechanical design, it is often required to use connectors that require no blockage during assembly, good sealing performance without leakage after assembly, and can provide the required locking torque. Conventional designs to meet the above requirements require the use of complex mechanical structures. Or adopt expensive new material to be matched with the lubricating material with higher cost to be coated on collectively and reach above-mentioned p...
