Pipeline connecting structure

The utility model discloses a pipeline connecting structure, which is characterized in that the end part of a first pipe body is a convex conical plug, a second pipe body is provided with a concave conical jack, the plug is positioned in the jack, the outer side wall of the plug is in contact with the inner side wall of the jack, a sealing ring is arranged between the end part of the plug and the inner end surface of the jack, and the sealing ring can ensure the sealing performance of pipeline connection. After the first pipe clamp and the second pipe clamp are connected through the locking structure, the first pipe body and the second pipe body can be connected, the locking structure adopts the mode that a plug pin is matched with a first pin hole and a second pin hole, operation is simpler, and pipeline butt joint can be achieved more conveniently. And on the basis that the sealing performance and the connecting strength are guaranteed, the connecting mode is more convenient. 本实用新型公开了一种管道连接结构，通过在第一管体的端部为凸锥形
