Technical Field

[0001] The utility model relates to the field of drag chains, and particularly to a quick - installation main plate structure of a silent drag chain. Background Art

[0002] Drag chains are generally applied to cables, oil pipes, air pipes, water pipes, and air ducts of machine tools, machinery, etc., playing the roles of traction and protection. During use, the drag chain becomes a protective shell for these pipelines and is located outside these pipelines. Nowadays, drag chains are widely used in the machinery industry, and there are various drag chains sold on the market, each with different design concepts, aiming to meet the usage requirements of different machines.

[0003] During the use of drag chains, actions such as bending and flipping are often required, which will generate relatively loud noises. mainly because when the drag chain flips, rigid collisions occur between various components, resulting in relatively large noise pollution. In response to this problem, several silent drag chains have been developed in the industry. However, the existing silent drag chains still have problems such as inconvenient assembly during the assembly operation, that is, it is difficult to solve the contradiction between the assembly convenience and the reliable combination of the drag chain.
