Problems solved by technology

In a commercial vehicle, the bracket 100 is generally installed on the vehicle frame, and the nut 200 is on the inside of the vehicle frame. During assembly, two people are required to operate, one tightens the bolt 300, and the other fixes the nut 200 with a wrench. Beams or other parts, it will be very difficult to fix the nut 200
Secondly, the structure of using the spring pad 400 for anti-loosening is single, and the effect is average.

Abstract

The invention discloses an anti-releasing device for nut positioning. The anti-releasing device comprises a framework (1) and liner plates (2). The framework (1) comprises framework bodies (11), connecting plates (12) and limiting plates (13). Multiple screw mounting holes (14) are formed in each framework body (11). Each limiting plate (13) is connected with the corresponding framework body (11) through the corresponding connecting plates (12). A screw mounting hole (14) is formed in each limiting plate (13) in a matched manner. A semi-circular groove (15) is formed in the end of each limiting plate (13). The liner plates (2) are the same as the framework bodies (11) in shape. Nut mounting holes (21) are formed in each liner plate (2). Each liner plate (2) is clamped and fixed between the corresponding framework body (11) and the corresponding limiting plate (13). By the adoption of the anti-releasing device for nut positioning, the assemblability of nuts can be improved, nut positioning is facilitated during assembly, manpower is saved, and nut releasing can be prevented effectively.

Description

technical field [0001] The invention relates to an auxiliary device, in particular to a nut positioning and anti-loosening device. Background technique [0002] In vehicle design, brackets are mostly fixed by bolt connections. Bolt connection is the most commonly used connection method. In this connection method, strength, looseness and ease of assembly are the most critical considerations. [0003] figure 1 For ordinary bolt connection. In a commercial vehicle, the bracket 100 is generally installed on the vehicle frame, and the nut 200 is on the inside of the vehicle frame. During assembly, two people are required to operate, one tightens the bolt 300, and the other fixes the nut 200 with a wrench. Beams or other components, securing the nut 200 will be very difficult. Secondly, the structure of using the spring pad 400 for anti-loosening is single, and the effect is average. Contents of the invention [0004] The purpose of the present invention is to provide a nu...
