Quick joint

Abstract

The invention discloses a quick joint, which is provided with a body, a valve seat and a shell, wherein the body is provided with a bonding end, a positioning end, an air inlet chamber, a clamping groove and an air outlet chamber; the body is provided with a return spring in the air outlet chamber; a plurality of air leakage holes which are communicated with the air outlet chamber run through the middle section of the body in the radial direction at intervals; the valve seat is arranged in the body in a movable mode and is provided with a closed end, an opening end, at least one air inlet communicated with the air inlet chamber and a butting ring; the shell is sleeved outside the body in the movable mode and is provided with a spring groove, a forcing groove and a pushing and butting spring; high-pressure air can be dispersed and discharged by the air leakage holes; and the body is formed integrally. The quick joint which is convenient to manufacture, reduces cost, has high maintenance speed, reduces faults and can be used safely is provided.

Description

technical field [0001] The invention relates to a quick connector, in particular to a quick connector which can be manufactured conveniently, reduces cost, can be maintained quickly, reduces faults and can be used safely. Background technique [0002] Please refer to as Figure 9 As shown, the quick connector 70 in the prior art is generally used for the connection of pipelines and is provided with a body 71, a positioning seat 72, a valve seat 73 and an outer casing 74, wherein the body 71 is a hollow cylinder with one end Used to connect with an air compressor (not shown in the figure), the positioning seat 72 is screwed with the other end of the body 71 and a plurality of sleeve holes 721 are arranged on the spacer ring on the outer surface, and each sleeve hole 721 A positioning bead 722 is provided, the valve seat 73 is set in the body 71 and has an air inlet 731 communicating with the inside of the body 71, the outer shell 74 is movably sleeved on the outer surface of ...

AI Technical Summary

Problems solved by technology

[0003] However, although the existing quick connector 70 can provide the effect of a quick connection pipeline, the existing quick connector 70 not only must make the body 71 and the positioning seat 72 respectively during manufacture, which will relatively increase the required manufacturing time. Cost and time, and the body 71 and the positioning seat 72 must be screwed together during assembly, which is quite inconvenient. In addition, the screwed joint between the body 71 and the positioning seat 72 of the existing quick connector 70 is difficult to use for a long time. In the end, it is easy to cause gas leakage, not only the connection of the pipeline cannot be accurately carried out, but also there will be hidden dangers;

[0004] Furthermore, although the existing quick joint 70 can be combined with a male joint (not shown) by sliding the positioning beads 722, so as to carry out gas transmission and use, but after use, it is de...
