Problems solved by technology

[0002] The pipes in the prior art are generally connected with the end faces of the two joints and then fastened with screws. Therefore, even if rubber pads are added between the joint surfaces, it is difficult to seal. Moreover, the structure of the joints fastened by screws It is complicated and inconvenient to operate, and the screws are easy to rust and difficult to disassemble. How to design a joint structure with sealing effect and self-locking has become a problem to be solved

Abstract

The invention discloses a fixing device of a pipeline joint with a self-locking structure. The pipeline joint comprises a male joint and a female joint which are arranged on a pipeline; the self-locking structure comprises an arc-shaped boss arranged on the cylindrical surface of one end of the male joint; the arc-shaped boss is matched with an annular groove formed in the inner wall of a cavity formed in one end of the female joint; yielding grooves penetrating through the bottom of the annular groove and the end surface of one end of the female joint are symmetrically formed in two sides of the inner wall of the cavity and matched with the arc-shaped boss; a first step surface is formed in the root of the cylindrical surface, aligns the arc-shaped boss on the male joint with the yielding grooves in the inner wall of the cavity of the female joint and is inserted into the yielding grooves, so that the first step surface on the male joint and the end surface of the female joint are fully attached; and the male joint is rotated for 90 degrees, so that the male joint and the female joint are locked, and the sealing effect is good due to the fact that a sealing ring is arranged at the attachment position of the locked joints. The pipeline joint with the self-locking structure is simple in structure, convenient to use and good in sealing effect, and self locking is convenient.

Description

technical field [0001] The invention relates to the technical field of pipeline accessories, in particular to a pipeline joint with a self-locking structure. Background technique [0002] The pipes in the prior art are generally connected with the end faces of the two joints and then fastened with screws. Therefore, it is difficult to seal even if a rubber pad is added between the joint surfaces. Moreover, the structure of the joints fastened by screws It is complicated and inconvenient to operate, and the screws are easy to rust and difficult to disassemble. How to design a joint structure with sealing effect and self-locking has become a problem to be solved. Contents of the invention [0003] The purpose of the present invention is to provide a pipe joint with a self-locking structure, which can make the sealing effect of the joints of the pipes better after butt joint, and can be self-locking. [0004] For reaching this purpose, the present invention adopts following ...
