As shown in fig. 3 and 5, a stop ring 11 for limiting the depth of pipe insertion is formed in the pipe joint body 1. The radius of the through hole of the limiting ring 11 is consistent with that of the through hole of the pipeline. There is an inevitable gap between the pipe and the pipe joint body 1. When water flows, inevitable water penetrates through the gap, the insertion degree of the pipeline is limited by the limiting ring 11, the gap is closer to the annular groove 21 of the sealing ring 2, and the technical effect is achieved more quickly. And the pipeline can be stably connected only by inserting a small part, and the pipeline and the pipe joint body 1 can be conveniently disassembled.
