The utility model has good sealing effect, is easy to disassemble and assemble, and will not be unable to be disassembled due to rust.

[0004] The existing sealing mechanism and water pipe adapter have problems in that the position where the adapter is connected to the water pipe is usually inserted into the inside of the water pipe and a sealing ring is provided from the inside for sealing, or the adapter is sleeved on the outside of the water pipe and a sealing rubber ring is provided from the outside for sealing. Usually, it is sealed only from one side of the inner wall or the outer wall of the water pipe, and the other side lacks a sealing structure. When in use, water leakage may occur. The existing adapter uses a leaf spring to clamp and fix the water pipe and the adapter. There is no limit component between the leaf spring and the water pipe, and it is only fixed by the friction force after the two are pressed together. After long-term use, the elasticity of the leaf spring may have problems, and the clamping force will be insufficient. The leaf spring may loosen or fall off from the connection, affecting the clamping and fixing effect. In addition, after the existing adapter is connected to two water pipes, the angle between the two water pipes is determined by the angle of the adapter and cannot be changed.
