Embodiment Construction

[0026] The present invention will be further explained below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 As shown, an embodiment of a quick connector includes a plastic connector body 1, a water outlet connector 4, and a detachable plastic large collar 2 and a small plastic collar 3 respectively fixed on the connector body 1 and the water outlet connector 4. The joint body 1 is a cylinder through the center, and the large collar 2 and the small collar 3 respectively include C-shaped bodies 51, 52 and two elastic side wings 61, 62 protruding longitudinally from the C-shaped body. The outer surface of the joint body 1 includes a collar groove 71 corresponding to the C-shaped body 51 of the large collar and having an outer diameter slightly larger than the inner diameter of the large collar. The limit block 8 for the rotation of the collar, the outer surface of the water outlet joint 4 includes a collar groove 72 corresponding to the ...

Abstract

The invention discloses a quick connector, which comprises a connector body, a water outlet connector, and small and big detachable clamping rings mounted on the connector body and the water outlet connector respectively. The water outlet connector is inserted in the back end of the connector body by extruding an elastic side wing of the small clamping ring on the water outlet connector, and the elastic side wing of the small clamping ring is embedded in a hole on the back end of the connector body due to outwardly extended elasticity thereof, so that the water outlet connector is fixedly connected with the connector body in tight manner. An elastic side wing of the big clamping ring is pressed, and a pressing block on the elastic side wing of the big clamping ring is greater in thicknessthan the connector body, so that the elastic side wing of the small clamping ring will be pressed down to drag the water outlet connector so as to separate the connector body from the water outlet connector. Because the small and big clamping rings are both in C ring structures, the small and big clamping rings can be conveniently detached from the connector body and the water outlet connector soas to be conveniently repaired and replaced. The invention also discloses a connecting method using the quick connector.

Description

technical field [0001] The invention relates to a joint, in particular to a quick joint used in the field of water pipes and a method for connecting pipes. Background technique [0002] In the prior art, welding or threaded connections are often used between various parts of the pipeline, but if welding is used, since the connection of pipelines, especially the connection of water pipelines, is mostly at a certain angle, the weld lines are not easy to be polished and polished, resulting in rough surfaces , causing inconvenient use, and welding is prone to false welding, making the connection not firm and affecting product quality. If screw connection is used, the screw is easy to loosen during use, which will reduce the firmness of the connection, and there will be gaps on the outer surface of the connection, which will not only subject the screw to twisting force, but also cause rust due to frequent contact with water. In addition, these traditional methods also have probl...
