Technical Field

[0001] The utility model relates to the field of pipelines, in particular to a pipeline quick joint assembly. Background Technique

[0002] In the prior art, during the assembly of the whole vehicle, due to the complex installation environment and space constraints in the engine compartment of the vehicle, the installation of the water pipeline is greatly restricted. At present, most of the clamping and fixing of the water pipeline adopts the elastic hoop or double-wire hoop fixing method. During the design, it will not only affect the operation space of the pipeline fixing standard parts, but also lengthen the vehicle manufacturing beat. Especially after using the standard parts for fixing, the reliability of the standard parts fixing cannot be eliminated in time.

[0003] Chinese patent document CN203223682 discloses a quick pipe joint. Inside the pipe joint body, there are three stepped holes from small to large in sequence, and a fixing ring, a special-shaped sealing ring and a plastic pipe are respectively arranged. The upper end surface of the fixing ring abuts against the lower end surface of the special-shaped sealing ring. A snap ring is arranged below the fixing ring, and a pressing ring is arranged below the snap ring. This pipe joint fixes the special-shaped sealing ring by setting the fixing ring, the snap ring and the pressing ring. However, these three rings can all rotate and there is no limit structure. After assembly, it is impossible to determine whether it is in place and it is easy to come off. In addition, the joint uses four rings, with more parts and more assembly processes, and it is easy to make mistakes. Summary of the Utility Model
