Abstract

The invention discloses a nut capable of being screwed up once and preventing loosening. The nut comprises a nut main body, an auxiliary tube, a limiting key, a key slot, a mounting hole, a first through hole, a second through hole, first inner threads and second inner threads, wherein the nut main body is hexagonal; one mounting hole is formed in the nut main body; one first through hole is formed in the bottom center of the mounting hole; one key slot with an upper-end opening is formed in the side wall of the mounting hole; the auxiliary tube is mounted in the mounting hole; one limiting key is fixedly arranged on the outer wall of the auxiliary tube; the limiting key is matched with the key slot; a second through hole which penetrates through upper and lower ends of the auxiliary tubeis formed in the auxiliary tube; the inner diameter of the second through hole is the same with that of the first through hole; and first inner threads are arranged in the first through hole. The auxiliary tube is mounted on the nut main body, and is sequentially matched with the first inner threads and the second threads formed by tapping, so that the nut can be screwed up once, is not liable toloosen after being screwed up, and the screw-up effect is effectively guaranteed.

Description

【Technical field】 [0001] The present invention relates to the technical field of machinery, especially the technical field of nuts. 【Background technique】 [0002] In the installation process of various machines, many connectors are used to connect and fix different parts, among which nuts are a commonly used connector. The existing nuts are prone to loosening during use and are not easy to be tightened sequentially. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a one-time tightening and anti-loosening nut, which can make the nuts be tightened sequentially and is not easy to loosen. [0004] In order to achieve the above object, the present invention proposes a one-time tightening and anti-loosening nut, including a nut body, an auxiliary pipe, a limit key, a keyway, a mounting hole, a first through hole, a second through hole, a first internal thread, The second internal thread, the nut body i...
