Problems solved by technology

[0002] In the mechanical structure design, in order to improve the wear resistance and extrusion strength of the joint, a bush with high strength and better wear resistance is often pressed into the connection hole of the joint. At the same time, in order to ensure the anti-loosening efficiency of the bush, the joint and Interference fits are usually used between the bushes, which will make it difficult to install and disassemble the bushings. Special tools are required for installation, and the bushes are easily damaged during disassembly, which will lead to problems such as the failure of the bushing surface protection measures. At this time, the bushings are damaged. It cannot be used repeatedly; and it will affect the fatigue strength and durability of the mechanical structure, and more seriously, it may cause damage to the mechanical structure around the bushing hole, or even destroy the joint

Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0015] see Figure 1~Figure 2 A bolt anti-loosening assembly, including a joint 1, a bush 2, a bolt 3, a washer 4, a nut 5, a cotter pin 6, an ear piece 7, a notch 8 and a small boss 9; wherein, the bush 2 has ears There is a notch 8 on the lug 7 and the lug 7, and a small boss 9 is installed at the joint between the joint 1 and the notch 8 of the bushing 2. When installing, the notch 8 of the bushing 2 is stuck on both sides of the joint 1. At this time, the gap between the joint 1 and the bushing 2 can prevent the bushing 2 from rotating freely, the bolt 3 is inserted into the bushing 2 and passes through the joint 1, then the nut 5 is tightened, and the split pin 6 Insert the bolt 3, and take conventional anti-loosening measures, so that the...

Abstract

The invention relates to a bolt locking assembly. The bolt locking assembly comprises a connector and a lining. The lining is sleeved with a lug sheet, a notch is formed in the lug sheet, and a small boss is arranged at the portion where the connector and the notch of the lining are installed in a clearance fit manner; and during installation, the small boss of the connector is clamped by the notch of the lining, and a bolt is inserted into the lining and penetrates the connector to be fastened through a nut. According to the bolt locking assembly, by optimizing the structures of the lining and the connector, the locking aim is achieved; and as the connector and the lining are in clearance fit, the lining is conveniently and rapidly demounted and mounted, the connector and the lining cannot be damaged during demounting, the lining can be repeatedly used, and the production cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical structures, in particular to a bolt anti-loosening component. Background technique [0002] In the mechanical structure design, in order to improve the wear resistance and extrusion strength of the joint, a bush with high strength and better wear resistance is often pressed into the connection hole of the joint. At the same time, in order to ensure the anti-loosening efficiency of the bush, the joint and Interference fits are usually used between the bushes, which will make it difficult to install and disassemble the bushings. Special tools are required for installation, and the bushes are easily damaged during disassembly, which will lead to problems such as the failure of the bushing surface protection measures. At this time, the bushings are damaged. It cannot be used repeatedly; and it has an impact on the fatigue strength and durability of the mechanical structure, and more seriously, it m...
