AI Technical Summary

Technical Problem

In order to ensure stable connection, flange needs to be relaxed and fixed when used, resulting in complex operation and easy loosening.

Method used

A flange with an anti-loose structure is designed. By providing a connecting mechanism on one side of the first flange, including a connecting sleeve, check teeth, bolts, wedge teeth and threaded holes, the bolts are tightened by interference fit to prevent the flange connection from being loosened, and components such as sealing gaskets, arc-shaped covers, and snap rings are used in the sealing mechanism to ensure the sealing effect.

Benefits of technology

It effectively prevents the connection of the flange from loosening, improves the stability of the connection, and enhances the sealing effect through the sealing mechanism, so as to maintain sealing performance when the water flow is washed.

Abstract

The utility model provides a flange with an anti-loose structure, and particularly relates to the technical field of flanges, the flange comprises a first flange and a second flange, a connecting mechanism is arranged on one side of the first flange, and the connecting mechanism comprises a connecting sleeve, non-return teeth, bolts, wedge-shaped teeth and threaded holes. The bolt penetrates through the first flange in a sliding mode and is in threaded connection with the threaded hole of the second flange, the wedge-shaped teeth are continuously screwed into the threaded hole to make contact with the non-return teeth, and the bolt is screwed down through interference fit, so that connection looseness of the first flange and the second flange can be prevented, and when the first flange and the second flange are in butt joint, the sealing gasket is arranged between the first flange and the second flange, so that the clamping ring on the arc-shaped cover is clamped. In this way, when water flow scours, the clamping ring can prevent the arc-shaped cover from tilting and impact the arc-shaped cover to enable the arc-shaped cover to be tightly attached to the inner wall of the flange, sealing can be better achieved, one end of the arc-shaped pad is tightly attached to the inner wall, and the sealing effect can also be achieved.
