quick connect tube

Abstract

The invention discloses a quick-coupling tube which comprises a base, a main body part, cover body parts, a sealing part and a tightening ring part, the main body part is shaped like a barrel, one end of the main body part is embedded in the base, the other end of the main body part protrudes relative to the base, each cover body part is shaped like a barrel and is arranged at the end, protruding relative to the base, of the main body part in a sleeving mode, gaps are formed between the inner walls of the cover body parts and the outer wall of the main body part, the tightening ring part is shaped like a circular ring, the sealing part and the tightening ring part are arranged between the base and the main body part, the sealing part is close to the main body part, a gap is formed between the sealing part and the tightening ring part, the inner diameter of one end of the tightening ring part is smaller than that of the other end of the tightening ring part, and transmission from the end, with the big inner diameter, of the tightening ring part to the end, with the small inner diameter, of the tightening ring part is achieved in a bevel mode. According to the quick-coupling tube, the installation speed is increased, the safety and the stability are achieved, and the service life is long.

Description

technical field [0001] The invention relates to the field of pipe connection, in particular to a quick connection pipe. Background technique [0002] Quickly connect pipe fittings, the outer seal is a commonly used method, but the outer seal also has its disadvantages, the seal ring is sealed with the outer wall of the pipe, because the outer wall of the pipe is easily damaged during production, transportation, and use, resulting in pipeline leakage, so The requirements for pipes are very high; the quick-connect pipe fittings with external sealing structure generally cannot be equipped with observation holes, and the leakage caused by improper installation is easy to occur during the installation of pipes, and the installers will draw lines to solve them, resulting in a decrease in installation speed. [0003] At present, some manufacturers modify the internal sealing structure of the O-ring. Although this structure solves the problem of observation holes and high requiremen...

[0002] Quickly connect pipe fittings, the outer seal is a commonly used method, but the outer seal also has its disadvantages, the seal ring is sealed with the outer wall of the pipe, because the outer wall of the pipe is easily damaged during production, transportation, and use, resulting in pipeline leakage, so The requirements for pipe materials are very high; quick-connect pipe fittings with external sealing structure generally cannot be equipped with observation holes, and during the installation of pipes, it is easy to cause leakage due to improper installation, and the installer will draw a line to solve it, resulting in a decrease in installation speed

[0003] At present, some manufacturers modify the internal sealing structure of the O-ring. Although this structure solves the problem of observation holes and high requirements for pipe materials, there are also small leaks caused by the reduction of the sealing amount. The aging of the seal, the decrease of the sealing amount will cause the leakage of the pipeline and the failure of the product seal
