[0002] The gas pipeline is a special pipeline for transporting combustible gas. It is a metal gas pipe hose that replaces the traditional snap-on rubber hose. It can solve the defects of rubber hoses that are easy to fall off, easy to age, easy to be bitten by insects, and have a short service life. It has the characteristics of easy installation, reliable connection, corrosion resistance, no gas blockage, good flexibility, long service life, and can be bent arbitrarily without deformation or gas blocking.
[0003] A docking device is used when docking gas pipelines. The two pipes are inserted into the docking device respectively, and then the docking device is tightened to complete the docking. However, the depth of the pipeline is guaranteed by the operation of the installer when it goes deep. The depth of the pipelines on both sides will be different. Gaps may appear between the pipelines on both sides, causing leakage. At the same time, the docking device is sealed through the internal rubber layer. After a gap appears between the pipelines on both sides, gas may leak after long-term use. For this reason, we propose a leak-proof gas pipeline docking device. Utility Model Content
