Novel never-falling nut and screw rod connecting structure

Abstract

The invention discloses a novel never-falling-off nut and screw connecting structure which comprises a nut and a screw and further comprises an elastic spiral body, outer barbs are evenly arranged on the outer wall of the elastic spiral body, inner barbs are evenly arranged on the inner wall of the elastic spiral body, the directions of the barbs of the outer barbs are opposite to the directions of the barbs of the inner barbs, and the barbs of the outer barbs and the barbs of the inner barbs are opposite to each other. The inner wall of the nut is provided with a nut inner thread matched with the elastic spiral body, the outer wall of the screw rod is provided with a screw rod outer thread matched with the elastic spiral body, the thorn tip direction of the inner barbs is opposite to the rotating direction of the nut, and the thorn tip direction of the outer barbs is the same as the rotating direction of the nut. When vibration occurs, the nut and the screw rod can rotate in opposite directions, so that the nut and the screw rod generate a locking effect, and the nut and the screw rod are not easy to loosen.

Description

technical field [0001] The invention relates to the technical field of nuts and screws, in particular to a novel never-falling-off nut and screw connection structure. Background technique [0002] Nuts and screws commonly used at present are indispensable and important parts for connection between mechanical parts and device fixing. Bolts and nut fasteners are very convenient to use, but after the nut is connected to the screw, if it is in a state of vibration for a long time Under the circumstances, the connection is prone to loosening and loosening, which will cause safety accidents. Therefore, a new type of connection structure that never falls off the nut and screw is designed to solve the problem of loosening of the nut and screw connection due to vibration. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a novel never-falling-off nut and screw connection structure. [0004] In order t...
