Description

Technical Field

[0001] The utility model relates to the technical field of machined parts, in particular to a locking nut with a quick-release structure. Background Art

[0002] A machined part is a mechanical part that can be used to connect, fix or support other parts. Usually, machined parts are made of metal or plastic. Machined parts can be divided into three categories, namely fasteners, transmission parts and positioning parts. Fasteners are used to connect two or more parts together, such as bolts, nuts and rivets; transmission parts are used to transmit power or motion, such as gears, sprockets and pulleys; positioning parts are used to determine the position of parts, such as pins and locating sleeves.

[0003] Locking nut is a kind of nut widely used in machinery and other industries. Its working principle is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking will be reduced under dynamic load. In some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking. The anti-loosening effect of locking nut mainly depends on the interaction force between the meshing threads of nut and bolt. There are many ways to improve the interaction force between meshing threads, such as structural improvement of nut thread, nylon roughening of nylon nut, surface treatment of thread, etc.

[0004] In the process of realizing the present invention, the inventors found that the prior art had the following problems: 1. The existing locking nuts are often complex in structure, which is time-consuming and labor-intensive to install, and there is no simple installation mechanism; 2. When the existing locking nuts need to be disassembled, repaired or replaced, the operator is often required to manually perform a lengthy disassembly operation, which wastes time and easily causes damage to parts, and lacks a quick-release structure. Utility Model Content

[0005] The purpose of the present invention is to provide a locking nut with a quick-release structure, so as to solve the problem that the existing locking nuts mentioned in the above background technology are often complicated in structure, time-consuming and labor-intensive to install, and lack a simple installation mechanism. When the existing locking nuts need to be disassembled, repaired or replaced, the operator is often required to manually perform a relatively lengthy disassembly operation, which not only wastes time, but also easily causes damage to parts and components, and lacks a quick-release structure. To achieve the above purpose, the present invention provides the following technical solutions: a locking nut with a quick-release structure includes a top cover, the inner wall of the top cover is clamped on the top of the nut body, the outer wall directly below the top of the nut body is provided with a first collar, the top of the first collar is plugged with a plurality of elastic clips, the bottom ends of the plurality of elastic clips are clamped on the top of the second collar, the inner wall of the second collar is sleeved with a column, and a screw hole is provided in the middle of the top of the nut body.

[0006] Further preferably, the inner wall of the top cover is annularly provided with a plurality of slots.

[0007] Further preferably, a plurality of blocks are distributed in an annular manner on the outer wall of the top end of the nut body.

[0008] Further preferably, the elastic clamp is composed of a clamping plate, a short spring, a long spring, and an ear-shaped plug rod, wherein the ear-shaped plug rod vertically passes through the top of the first retaining ring, and a short spring is provided at the top of the ear-shaped plug rod, and a long spring is provided at the bottom thereof, and clamping plates are provided at the ends of the short spring and the long spring.

[0009] Further preferably, four short slots are provided in a ring shape at the bottom of the top cover.

[0010] Further preferably, four long slots are provided in a circular shape on the top of the second retaining ring.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, the grooves annularly distributed on the inner wall of the top cover are aligned with the block positions annularly distributed on the outer wall of the top end of the nut body, and then the block is inserted to the bottom along the inner wall of the groove. During this period, the elastic card piece is also simultaneously inserted into the short slot provided at the bottom of the top cover to complete the installation between the two. When the two need to be disassembled, the operator only needs to manually press the elastic card piece inserted into the short slot and press it back into the short slot to release the position limitation between the top cover and the locking nut, and at the same time pull the nut body downward so that the block provided on the nut body can slide downward along the groove provided on the top cover until the two are completely separated, and the top cover can be disassembled from the entire locking nut.

[0013] The locking nut is then disassembled by the operator manually pressing the clamping plates at the ends of the short spring and the long spring respectively, so that the clamping plates at the two locations are pressed back into the short slot and the long slot respectively, thereby separating the top cover, the column and the nut body from each other, and then quickly completing the disassembly operation of the locking nut.
