[0026] like Figures 1-5As shown, this embodiment provides a polyethylene pipe, including a first pipe body 1, a splicing structure, and a second pipe body 4. The first pipe body 1 is connected to the second pipe body 4 through the splicing structure. The splicing structure includes a first splicing component 2 and a second splicing component 3. The first splicing component 2 includes a first threaded connecting segment 5, a first splicing segment, and a configuration connecting segment 7 connected in sequence. The first threaded connecting segment 5 is used for butt-fitting installation to the end of the first pipe body 1. The first splicing segment is used for connecting the threaded connecting segment and the configuration connecting segment 7. The configuration connecting segment 7 is used for connecting the second splicing component 3. The second splicing component 3 includes a second threaded connecting segment 12, a second splicing segment 11, and an annular clamping segment 10 connected in sequence. The second threaded connecting segment 12 is used for butt-fitting installation to the end of the second pipe body 4. The second splicing segment 11 is used for connecting the second threaded connecting segment 12 and the annular clamping segment 10. The annular clamping segment 10 is used for butt-fitting installation of the configuration connecting segment 7.

[0027] The first threaded connecting segment 5 is an annular structure with external threads. One end of the first threaded connecting segment 5 is connected to one end of the first splicing segment, and can be integrally formed or welded. The other end of the first connecting segment 6 is provided with a configuration connecting segment 7. The configuration connecting segment 7 includes multiple configuration components evenly distributed along the circumference of the first connecting segment 6, with a set spacing between the configuration components. The configuration components include rectangular segments and triangular segments. The rectangular segments are elastic structural segments that can be bent and deformed so that the triangular segments tilt at a certain angle and enter the slot 8 of the second splicing component 3, and then return to their original position. In the initial state, the two are connected. One side of the triangular segment is arc-shaped, and the other side is horizontal. The arc-shaped side is used to mate and install into the slot 8 of the second splicing component 3, and the horizontal side of the triangular segment is used to lock into the slot 8. After the component is mated and installed with the slot 8 of the second splicing component 3, a fixed structure is formed. When disassembly is required, it needs to be removed from the first tube 1 and the second tube 4, and then the two splicing components need to be separated using tools. The rectangular segment of the component is provided with a sealing ring, which is used to achieve a sealing effect.

[0028] The second threaded connecting section 12 is an annular structure with external threads. The end of the second threaded connecting section 12 is connected to one end of the second splicing section 11. It can be integrally formed or welded. The other end of the second connecting section is provided with an annular clip and section 10. The inner side of the annular clip and section 10 is provided with a slot 8. The slot 8 is used to cooperate with the connecting section 7. The inner side of the annular clip and section 10 is also provided with a guide protrusion 9 at the port. The guide protrusion 9 is used to limit and guide the triangular section of the component to avoid slippage during the docking process and damage to the component.

[0029] Firstly, the traditional connection of two sections of polyethylene pipe mostly relies on flanges. Flanges are fabricated at both ends of the pipe, and bolts are used to connect the two flanges, thus completing the pipe connection. However, bolted connections require tools such as wrenches, as it is difficult to tighten bolts by hand. Furthermore, there is a risk of bolts falling off during installation, making it inconvenient. To address this, this application first uses a first splicing component 2 and a second splicing component 3, which are then wrapped with waterproof tape and threaded onto the ends of the two pipes to ensure a tight, leak-free seal between the two pipes and the splicing components. Then, the ends of the two pipes are joined together using the splicing components. A sealing ring is installed between the connectors. After the connectors are installed, the sealing ring seals the installation point, thus connecting the two pipes. This method of installation is simple and does not require wrenches, bolts, or other connecting parts. The installation is also secure. The connectors are internally fixed after installation and cannot be disassembled externally. When disassembly is required, they can be removed from the connector using the threaded connection between the two pipes. The disassembled connector can be separated using disassembly tools such as pliers. Of course, this type of connector is generally a one-time installation and may become unusable due to excessive deformation during disassembly. However, this structure allows for convenient installation and is suitable for quick and easy connection and installation during pipeline laying.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
