Self-lock nut with lining

Abstract

The invention discloses a self-lock nut with a lining. A nut body is included and comprises a support plate and the lining. The lining is composed of an upper lining section and a lower lining section. The upper lining section and the lower lining section are coaxially arranged in the support plate. Mutual-connection through holes are formed in the upper lining section and the lower lining sectionforming the lining. An installing hole is further formed in the support plate. By adoption of the self-lock nut, the upper lining section can be utilized for offsetting a disqualified bolt hole in astructure, adverse influences caused by the disqualified bolt hole in a fixing piece can be effectively avoided, loads of a bolt can be effectively transmitted to a structure piece through the self-lock nut, and potential safety hazards are eliminated. The structure is simple, usage is convenient, cost is low, the self-lock nut is high in universality, an original-specification bolt can be installed at the original position, structure component scrapping is avoided, materials are saved, cost is reduced, safety and practicability are achieved, and the self-lock nut is suitable for popularization and usage.

Description

technical field [0001] The invention relates to the technical field of fastener connection, in particular to a self-locking nut with a bushing. Background technique [0002] Bolts and nuts are common fasteners, by using bolts and nuts, different parts can be connected, so that two or more components can be mechanically fixed in one mechanical component. Locking with nuts is a commonly used mechanical connection method in the prior art, and is widely used in various mechanical industries. Self-locking nuts are commonly used in structural connections in aviation, aerospace, ships, high-speed rail and other industries. In the actual assembly and connection process, when it is necessary to expand the bolt holes on the fixing parts, it is inevitable that the bolt holes on the fixing parts will be enlarged or deviated during the hole expansion process, resulting in uneven bolt holes. In qualified cases, when there is a load that needs to be transmitted through the bolts, due to t...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is aimed at the problems existing in the background technology. In order to eliminate the adverse effects brought by the unqualified bolt holes on the fixing parts, a self-locking nut is provided, and the bolts of the original specification can still be installed in situ , and eliminate its potential safety hazards. After compensating by installing self-locking nuts, it can effectively solve the problem of unqualified bolt holes on the fixing parts. Because there is a gap after the connection, the bolts cannot directly and effectively transmit the load. Specifically It is a self-locking nut with a bushing
