Problems solved by technology
[0002] As we all know, the locking connection device of the general telescopic expansion tube usually uses an outer thread sleeve, which is locked with a nut or a slope. Not only are there many accessories, but the connection is inconvenient, and there are also phenomena such as water leakage and air leakage.
Chinese patent 94245870.2 utility model patent discloses a self-locking sealing pipe fitting, which is composed of a pipe fitting body, a back cap, and a self-locking gasket. The structure of the connection device is relatively complex, and the processing difficulty is relatively large. In addition, in the process of use, the connection is inconvenient, the use is inconvenient, the reliability is poor, and the sealing performance is also relatively poor. There are water and air leakage phenomena under high pressure. It is very inconvenient to use
