They are diverse in types, including pipe clamps, internal pipe clamps, union joints, quick connectors, bushings, elbows at various angles, pipe plugs, tees, crosses, and valves, etc. Each connector has its specific uses and connection methods. When connecting pipelines, after workers dock two pipelines, they use pipeline connectors to connect the two pipelines. Existing connectors may not provide sufficient sealing effect and cannot effectively block high-pressure water flow. When the water pressure is high, it is very easy for water to leak out from the gaps between adjacent pipelines. Summary of the Utility Model

[0008] Preferably, the positioning component includes a connecting plate. The connecting plate is fixedly installed on the body of the connecting ring;

[0009] A connecting groove is formed on the upper surface of the connecting plate, and two connecting blocks are slidably arranged in the connecting groove. Clamping structures for clamping a transport pipe are arranged on the upper surfaces of the two connecting blocks.

[0010] A control structure for controlling the movement of the connecting block is arranged between two sides of the inner wall of the connecting groove.

[0011] Preferably, the clamping structure includes a mounting frame fixedly installed on the upper surface of the corresponding connecting block. A first bidirectional screw rod is rotatably installed between two sides of the inner wall of the mounting frame, and pipe clamps are threadedly arranged on both sides of the rod body of the first bidirectional screw rod.

[0030] The staff inserts the pipe openings of the two pipelines into the corresponding sealing grooves 402, so that the pipe openings of the pipelines are inserted and matched with the annular sealing gasket 401, enhancing the sealing performance. Subsequently, the staff uses the clamping structure 504 to clamp the two pipelines, and then activates the control structure 505 to drive the connection block 503 to move, so that the two clamping structures 504 drive the corresponding pipelines to move relatively, and further enable the pipe openings of the two pipelines to be inserted more tightly into the corresponding sealing grooves 402, further enhancing the sealing performance, and thus providing sufficient sealing effect, effectively blocking the high-pressure water flow, and avoiding the situation that the water flows out from the gap between adjacent pipelines when the water pressure is high.
