[0027] like Figures 1-6 As shown, this utility model provides a technical solution: a tensile-resistant PE pipe, including a left original pipe 1 and a right original pipe 104, a fixing component 2, which is disposed between the left original pipe 1 and the right original pipe 104 for fixing the connection between the left original pipe 1 and the right original pipe 104, and a socket component 3, which is disposed on the inner wall of the left original pipe 1 for inserting the right original pipe 104 into the left original pipe 1.

[0028] like Figures 1-6As shown in the embodiment of this application, the socket assembly 3 includes a guide groove 302 located on the inner wall of one end of the left original pipe 1. An annular groove 305 is also provided on the inner wall of the left original pipe 1. A fixing block 301 is provided in the guide groove 302, and a sealing ring 303 is provided in the annular groove 305. A traction groove 306 is provided at the end of the left original pipe 1 opposite to the right original pipe 104, and a telescopic tube 304 is provided in the traction groove 306. Specifically, the pipe can be connected during the rotation of the fixing block 301 within the guide groove 302. During pipe connection, the fixing block 301 on the outer wall of the extension tube 105 at one end of the right original pipe 104 is aligned with the inlet of the guide groove 302. After the fixing block 301 is aligned, the right original tube 104 is pushed in so that the fixing block 301 abuts against the edge of the guide groove 302. Then, rotating the right original tube 104 can drive the fixing block 301 to rotate within the guide groove 302. The guide groove 302 provides the direction of movement for the fixing block 301 and restricts its movement. The fixing block 301 rotates from the entrance of the guide groove 302 to the edge of the endpoint, pulling the right original tube 104 to move horizontally. During the horizontal movement of the right original tube 104, the fixing block 301 moves along the axial direction of the original tube, so that the fixing block 301 enters the endpoint. The guide groove 302 is U-shaped, with one end penetrating through the left original tube 104. The outer side is the entrance, and the other end is a certain distance from the point where the left original pipe 1 passes through, which is the endpoint. After the fixing block 301 enters the endpoint, it is confined within the guide groove 302. It should be noted that the fixing block 301 is located on the outer wall of the extension pipe 105. During the movement of the fixing block 301 within the guide groove 302, the extension pipe 105 is always covered by the sealing ring 303. The sealing ring 303 enables the extension pipe 105 to form a sealed connection with the inner wall of the left original pipe 1. The flow direction within the original pipe is from the right original pipe 104 to the left original pipe 1. During the movement of the fixing block 301 within the guide groove 302, the telescopic pipe 304 will extend and retract synchronously to accommodate the extension pipe 1. 05 moves back and forth within the left original pipe 1. The two ends of the telescopic pipe 304 are located within the traction groove 306. The telescopic pipe 304 and the traction groove 306 are sealed together, but the telescopic pipe 304 is not fixed within the traction groove 306. The telescopic pipe 304 is movably positioned within the traction groove 306. The telescopic pipe 304 wraps around the extension pipe 105, but does not contact the extension pipe 105, and there is still a certain distance between them. After the telescopic pipe 304 connects between the left original pipe 1 and the right original pipe 104, it protects the gap between them, that is, the part of the extension pipe 105 exposed to the air. The traction groove 306 is closer to the outer wall of the original pipe than the guide groove 302.
