Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] figure 1 A schematic structural view of an embodiment of the present invention applied to elbow connection is shown. The quick-connect pipe joint includes a joint pipe 1, a mounting base 2, a mounting head 3, a snap ring 4 and an auxiliary snap ring 5; the end of the joint pipe 1 has a boss 11 protruding radially outward, and the outer diameter of the boss 11 is Slightly smaller than the inner diameter of the section 6 to be taken over.

[0026] The mounting base 2 includes a first mounting base 21 and a second mounting base 22. The first mounting base 21 and the second mounting base 22 are detachably fastened to the outside of the joint pipe 1 and have a joint pipe adapting to the shape of the joint pipe inside. Cavity 23; the end of the mounting seat 2 has a threaded lumen 24, the inner diameter of the threaded lumen 24 is larger than the joint lumen 23, an...

Abstract

The invention discloses a quick-connect pipe joint, which comprises a detachable mounting head and a mounting seat; the mounting head and the mounting seat cooperate to press a snap ring and make it undergo irreversible deformation, so that the snap ring is pressed against the pipe section to be connected, The section to be taken over is also deformed irreversibly when it is pressed, and is pressed against the joint pipe inside, so as to realize the connection and sealing between the joint pipe and the section to be taken over. The invention reduces the size of the quick-connect pipe joint, which is beneficial to reduce the manufacturing cost, and is especially beneficial for installation and use in equipment with compact space; on the other hand, the installation method of the invention is simple, with few or no installation tools, Manufacturing and maintenance costs can be further reduced.

Description

technical field [0001] The invention relates to the technical field of pipe joints, in particular to a quick-connect pipe joint and a use method thereof. Background technique [0002] Quick connect pipe joints, referred to as quick joints, are used for the connection of two or more fluid pipelines. Existing quick connectors generally use a self-locking structure including elastic elements such as springs to lock the pipe segment inserted into the joint to prevent it from coming out, thereby realizing the connection of the pipe segment. Since the installation of the quick connector requires only a few tools or even no tools, it is easy to use and easy to maintain, so it has been widely used in the field of pipeline installation. Quick connectors are also widely used in instruments and equipment. The installation space of these instruments and equipment is often tight, and small-sized connectors are preferred. However, limited by the existence of the self-locking mechanism, ...
