Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gas pipe fittings technology, and in particular relates to a gas pipe fitting. Background Technology
[0002] Gas pipes are specialized pipelines for transporting combustible gases. They are flexible metal gas hoses that replace traditional clip-on rubber hoses, overcoming the drawbacks of rubber hoses such as easy detachment, aging, insect infestation, and short lifespan. Gas pipes are easy to install, have reliable connections, are corrosion-resistant, do not clog, are flexible, have a long service life, and can be bent freely without deformation or gas obstruction. The soft protective layer material on the surface is safer, easier to clean, and aesthetically pleasing. Stainless steel threaded metal hoses have a service life of 8 years. In China's municipal pipe market, plastic pipes are steadily developing, with PE, PP-R, and UPVC gas pipes all holding a place. Among them, the strong growth momentum of PE pipes is most remarkable, and its application areas are very wide.
[0003] When existing gas pipe fittings require replacement of joints during maintenance, the pipe body often needs to be cut. However, as the usage time increases and the number of maintenance sessions increases, the pipe fittings are cut shorter and shorter, eventually requiring complete replacement, which increases maintenance costs. Therefore, we have specially designed a new type of gas pipe fitting. Utility Model Content

A limit protrusion is provided on the outer wall surface of the connecting sleeve port. The movable joint is slidably disposed on the outside of the connecting sleeve and at the front end of the second tubular joint. The movable joint is in a limiting fit with the limiting protrusion. Braided tubing, comprising a flexible hose and a braided mesh tube, wherein the two ends of the flexible hose are connected to a first tubular connector and a second tubular connector, and the braided mesh tube is disposed on the outer wall surface of the flexible hose; The movable joint is provided with a deformation groove, which extends from the upper end face of the movable joint to the lower end face.
[0006] In the above technical solution, the movable joint is made of plastic material and has a limiting fit with the connecting sleeve.
[0007] In the above technical solution, further, a sealing ring is disposed inside the limiting protrusion and on the wall surface of the connecting sleeve.
[0008] In the above technical solution, further, the diameter of the part where the second tubular joint connects to the connecting sleeve is larger than the diameter of the connecting sleeve.
[0009] In the above technical solution, the port portions of the first tubular connector and the second tubular connector are further provided with tubular interfaces; The flexible hose is located on the outside of the tubular interface and is connected to a spring buckle.

The movable joint 3 is provided with a deformation groove 31, which extends from the upper end face to the lower end face of the movable joint 3.
[0016] As can be seen from this embodiment, a gas pipe fitting includes a hexagonal connector 1, a connecting sleeve 2, a movable connector 3, and a braided pipe fitting 4; The bottom of the hexagonal connector 1 is formed with a first tubular connector 11, the wall of the connecting sleeve 2 is smooth and connected with a movable connector 3, and the bottom of the connecting sleeve 2 is formed with a second tubular connector 21. The upper part of the connecting sleeve 2 is formed with a limiting protrusion 22. The movable connector 3 is slidably connected to the connecting sleeve 2 and is limited and fixed to the connecting sleeve 2 by the limiting protrusion 22. When in use, the connecting sleeve 2 is used to connect the gas pipe fittings with external pipe fittings. Furthermore, a deformation groove 31 (milled) is provided on the movable joint 3 along the axial direction. After the movable joint 3 is deformed by the deformation groove 31, it passes through the limiting protrusion 22 and is fixed together with the connecting sleeve 2.
[0017] The braided fitting 4 includes a flexible hose 41 and a braided mesh 42. The flexible hose 41 gives the gas fitting flexibility and deformability, making it convenient for pipeline layout during use. The braided mesh 42 helps to improve the overall tear resistance of the braided fitting 4, thereby increasing its service life.
