Embodiment 1

[0032] like Figure 1-4 As shown, a quick connector provided in this embodiment includes a casing 1 with an assembly channel and a sealing ring 2, the casing 1 includes more than two connection ports 3, the sealing ring 2 includes a sealing cylinder 4 and There are 3 sealed outlets 5 with the same number as the connection ports, and each sealed outlet 5 is located in the connection port 3. The shell 1 also includes an upper half shell 6 and a lower half shell 7 that can be assembled and disassembled. Half shell 6 and lower half shell 7 are all provided with a semicircular groove 8, and the breach on the semicircular groove 8 on the upper half shell 6 and the lower half shell 7 is combined mutually and constitutes for Install the position-limiting pipeline 9 of the sealing cylinder 4, be provided with the first semicircular notch 10 that is identical with the number of connection ports 3 and the distribution position of the connection port 3 tops on the upper half housing 6, an...

Embodiment 2

[0035] like Figure 5As shown, the general structure of a quick connector provided in this embodiment is the same as that of Embodiment 1, the difference is that, as a preference, in order to facilitate the three-channel connection, the outer shell 1 and the sealing cylinder 4 are in the form of a three-way pipe , that is, the outer shell and the inner sealing cylinder 4 are set in the form of a tee. When installing, first use a special convex tube machine to protrude a ring of flanges on both sides of the upper half of the shell 6 and the lower half of the shell 7 at the corresponding positions. Extend the convex edge 13, and then insert the connecting pipe body part that needs to be installed on the three sides into the sealing ring 2, and then place the semicircular grooves 8 on both sides of the upper half shell 6 and the lower half shell 7 in the sealing ring 2 The two sides are spliced ​​together to form the limit pipe 9 of the seal ring 2. At the same time, the two side...

Embodiment 3

[0037] like Figure 6-8 As shown, the general structure of a quick connector provided in this embodiment is the same as that in Embodiment 1, the difference is that, as a preference, in order to improve the position-limiting effect, a position-limiting protruding ring 15 is provided on the outer wall of the sealing outlet 5, and the The sealing outlet 5 cooperates with the position-limiting convex ring 15 to form a hook structure 21, and the structural structures 21 on both sides cooperate with the half-side inclined steps 22 provided on the corresponding side of the semicircular groove 8, and the upper half of the housing 6 and the lower half After the two sides of the housing 7 are aligned, the two half-side inclined steps 22 on the same side cooperate with each other to form a limiting step surface 23 for clamping the hook structure 21 .

[0038] By setting the limit protruding ring 15 and the setting of the hook structure 21, and using the limit step surface 23, after the ...

Abstract

The invention discloses a quick connector. The quick connector comprises a shell and a sealing ring; the shell comprise two or more connection ports; the sealing ring comprises a sealing barrel body and sealing outlets, and each sealing outlet is located in the corresponding connection port; the shell further comprises an upper half shell body and a lower half shell body, and the upper half shellbody and the lower half shell body are each provided with a semi-circular groove; the upper half shell body is provided with first semi-circular notches which are the same with the connection ports inquantity and upper portion distribution position; the lower half shell body is provided with second semi-circular notches; each first semi-circular notch and the corresponding second semi-circular notch form the integrated connection port after being matched; each connection port is internally provided with a positioning concave ring used for installing a flange on the outer side of a connectionpipe body; extending convex edges extending outwards are arranged in side edges, opposite to the semi-circular grooves, of the upper half shell body and the lower half shell body; and the extending convex edges of the upper half shell body and the lower half shell body are locked and fixed through two or more bolts after being attached to each other. The quick connector is simple in structure, easy to operate and relatively convenient to install.

Description

technical field [0001] The invention relates to the technical field of a joint, in particular to a quick joint that is suitable for connecting a compressed air supply source and a pipe fitting and can be connected to a compressed air transmission path. Background technique [0002] In the prior art, the quick connector used on the pipeline is usually installed on a compressed air supply source, and a pipe fitting can be quickly disassembled through the assembly structure through the cooperation of components. [0003] When the existing quick connector is connected with compressed air, the pipe can be washed off by the compressed air, and finally lacks a safety mechanism. Therefore, when the existing quick connector is in a connected position, if the pipe is accidentally loosened Not only the compressed air will be ejected, but the pipe fitting may also splash out due to high pressure. Therefore, the existing joints have the following problems: 1. Potential danger and safety ...
