In water supply and drainage, pipe fittings generally need to be connected through joints.

[0003] For example, Chinese patent CN205534728U discloses a pipe connection joint, including a connector connected at both ends, the connector including a fixing member and connecting ends arranged at both ends of the fixing member and capable of extending into the pipe, the two connecting ends of the connector are respectively sleeved with end covers, the end covers include a limiting end and a fixing flange, the limiting end is a conical cross-section pipe structure, the connector is provided with a connecting flange, the end cover and the connector are fixedly connected by a fixing flange and a connecting flange, and the connector is an integrated structure.

[0004] The existing pipe fittings adopt an integral structure, which makes manufacturing more convenient, and the use of plastic as the main material greatly reduces the weight and manufacturing cost of the joint. However, when the joint is actually used, if the water valve is in an open state, the water pressure inside the water pipe is relatively high, causing the water inside the water pipe to spray out rapidly, and when the water pipe is disassembled and assembled to the joint, the water valve needs to be closed, which makes the joint inconvenient to use. Therefore, a pipe fitting connection joint is proposed to solve the above problems. Utility Model Content
