Description

A kind of washer-integrated type lock nut carrying flat spring washer
[technical field]
The present invention relates to the technical fields of nut, the especially technical field of washer-integrated type lock nut.
[background technique]
Nut is exactly nut, is threaded together the part for playing the role of fastening, all manufacturing machines with bolt or screw rod Tool must a kind of element according to the difference of material, be divided into several big types such as carbon steel, stainless steel, non-ferrous metal, nut is one The fixed tool of kind, there is hole at center, has screw thread on the inside of hole.The screw that nut is often harmonious with size shares, to be fixed with The engagement part of pass.If the environmental factors such as vibration enable nut loosen, the tools such as glue or safety pin of can be used further are related Part is reinforced.Nut is in hexagon more, next is square, and existing nut structure is simple, needs to improve fastening performance more Cooperation plain washer, spring washer are used together, but existing plain washer and spring washer need in addition addition, it has not been convenient to be operated, and be needed In addition plain washer and spring washer are carried, inconvenient to use, nut plain washer and spring washer after disassembling also are easily lost.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, a kind of washer-integrated type lock for carrying flat spring washer is proposed Tight nut can be integrated plain washer and spring washer, facilitate the installation of nut, improve the anti-loosening performance of nut.
To achieve the above object, the invention proposes a kind of washer-integrated type lock nuts for carrying flat spring washer, including spiral shell Cap ontology, spring washer, plain washer, plain washer upper bracket, the nut body inside center are equipped with thread cavity, the spiral shell Line chamber lower end is equipped with the plain washer upper bracket activity lock chamber that can cooperate with plain washer upper bracket, the plain washer upper bracket Movable lock chamber upper end is connected to thread cavity, and the thread cavity and plain washer upper bracket activity lock chamber are through nut body Upper and lower ends, the plain washer upper bracket upper end are set in plain washer upper bracket activity lock chamber and live with plain washer upper bracket Dynamic lock chamber slidable connection, the plain washer upper bracket lower end are equipped with plain washer, also cover on the plain washer upper bracket Equipped with spring washer, the spring washer coupling nut ontology lower end surface and plain washer.
Preferably, the plain washer upper bracket upper end is equipped with plain washer upper bracket annular rib, the thread cavity Lower end is equipped with the thread cavity that can cooperate with plain washer upper bracket annular rib and limits rib, the described thread cavity limit rib with The cooperation of plain washer upper bracket annular rib is by the limit of plain washer upper bracket upper end in plain washer upper bracket activity lock chamber.
Preferably, the plain washer upper bracket inside center is equipped with the plain washer upper bracket that can cooperate with thread cavity Through-hole.
Preferably, the plain washer upper bracket through-hole diameter is slightly larger than the diameter of thread cavity.
Preferably, the plain washer upper bracket and plain washer are integrally formed.
Preferably, the plain washer lower end surface is uniformly provided with several non-slip textures.
A kind of washer-integrated type lock nut for carrying flat spring washer of the present invention the utility model has the advantages that the present invention by will be under nut End setting spring washer and plain washer, by plain washer upper bracket by spring washer and plain washer and the movable connection of nut, spiral shell Cap is not necessarily in addition carry plain washer and spring washer during installation, facilitates the installation of nut, improves the anti-loosening performance of nut, nut After disassembling, plain washer and spring washer are still and nut is in one, and plain washer and spring washer are not easy to lose.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.
