Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to a polyethylene double-wall corrugated pipe. Background Art

[0002] Polyethylene double-wall corrugated pipe is a new type of pipe with an annular outer wall and a smooth inner wall. After more than ten years of development and improvement, it has developed from a single variety to a complete product series. It is very mature in production process and application technology. Due to its excellent performance and relatively economical cost, it has been widely promoted and applied.

[0003] Most of the existing polyethylene double-wall corrugated pipes are connected by welding when docking with adjacent corrugated pipes. However, when docking large-volume corrugated pipes, multiple workers are required to continuously adjust the docking position of the corrugated pipes so that the pipe openings of the two corrugated pipes always remain corresponding, which is time-consuming and labor-intensive. The welding fixing method takes a lot of time, and multiple workers are required to position the corrugated pipes during the welding process, resulting in reduced installation efficiency.

[0024] Reference Figure 1-4 A polyethylene double-wall corrugated pipe comprises a corrugated pipe body 1, a connecting pipe 3 and a connecting pipe 4. A reinforcement layer 2 is fixedly connected inside the corrugated pipe body 1. A transfer pipe 7 is fixedly connected to one end of the corrugated pipe body 1. A connecting pipe 3 is arranged on the side of the transfer pipe 7 away from the corrugated pipe body 1. Handles 11 are arranged on both sides of the connecting pipe 3. A connecting block 12 is fixedly connected to the side of the handle 11 close to the connecting pipe 3. A limiting block 13 is fixedly connected to the end of the connecting block 12 away from the handle 11. An engaging groove 14 is arranged on the connecting pipe 3. The end of the corrugated pipe body 1 away from the connecting pipe 3 is fixedly connected to the connecting pipe 4. The side of the connecting pipe 4 away from the corrugated pipe body 1 is fixedly connected to the engaging block 15. Grasp the handle 11, rotate the connecting pipe 3, and insert the engaging groove 14 of the connecting pipe 3 on one of the corrugated pipe bodies 1. The engaging groove 14 is rotated to align with the engaging block 15 of the connecting pipe 4 on the adjacent corrugated pipe body 1, the engaging block 15 is embedded in the engaging groove 14, and the handle 11 is pushed toward the engaging groove 14 so that the limit block 13 is embedded in the positioning hole 16. At this time, the fixing bolt 6 is used to penetrate the fixing block 5, and the fixing bolt 6 is fixed in the fixing hole 17 on the connecting pipe 4, so that the two adjacent corrugated pipe bodies 1 can be fixedly connected. By connecting the two corrugated pipe bodies 1 in a manner that the engaging block 15 and the engaging groove 14 are engaged with each other, the steps of repeatedly adjusting the positions of the corrugated pipe bodies 1 by multiple workers are reduced, which is convenient for users to quickly connect the adjacent corrugated pipe bodies 1, and it is more convenient to use the fixing bolt 6 to fix the adjacent corrugated pipe bodies 1 after the connection is completed, thereby improving the installation efficiency of the device.

[0025] Furthermore, a rotation groove 10 is provided on one side of the adapter tube 7 close to the connecting tube 3 , a fixing ring 9 is fixedly connected to one side of the connecting tube 3 close to the rotation groove 10 , and the rotation groove 10 passes through the adapter tube 7 on one side close to the connecting tube 3 .

[0026] Furthermore, a connecting block 8 is fixedly connected to the side of the fixing ring 9 away from the connecting tube 3. The connecting block 8 and the fixing ring 9 are movably engaged in the rotating groove 10. The movable engagement allows the connecting block 8 and the fixing ring 9 to rotate in the rotating groove 10, thereby adjusting the angle of the connecting tube 3.

[0027] Furthermore, a fixing block 5 is fixedly connected to a side of the handle 11 away from the corrugated pipe body 1 , and a fixing bolt 6 is penetrated through the fixing block 5 . The handle 11 is convenient for a user to rotate the connecting pipe 3 .

The connecting tube 3 can be rotated outside the transfer tube 7 through the connecting block 8 and the fixing ring 9 that are movably engaged with the rotating groove 10. The engaging groove 14 of the connecting tube 3 on one of the bellows main bodies 1 is rotated to align with the engaging block 15 of the connecting tube 4 on the adjacent bellows main body 1, and the engaging block 15 is embedded in the engaging groove 14. When the engaging block 15 is completely embedded in the engaging groove 14, push the handle 11 toward the engaging groove 14 so that the limit block 13 on the handle 11 is embedded in the positioning hole 16 on the engaging block 15. At this time, use the fixing bolt 6 to penetrate the fixing block 5 and fix the fixing bolt 6 in the fixing hole 17 on the connecting tube 4, so that the two adjacent bellows main bodies 1 can be fixedly connected.
