Description

Technical Field

[0001] This utility model relates to the field of double-wall corrugated pipe technology, specifically a convenient-to-assemble HDPE double-wall corrugated pipe. Background Technology

[0002] HDPE double-wall corrugated pipe is a type of plastic pipe made of high-density polyethylene (HDPE) with an outer wall featuring a ring-shaped corrugated structure and a smooth inner wall. Due to its excellent physical properties, corrosion resistance, and long service life, HDPE double-wall corrugated pipe is widely used in municipal engineering fields such as drainage and sewage discharge. When using double-wall corrugated pipe, two double-wall corrugated pipes are often spliced ​​together.

[0003] Traditionally, the connection between two adjacent double-wall corrugated pipes lacks stability. Under external forces or media pressure impacts, loosening and detachment can easily occur, affecting the sealing and overall performance of the piping system. Therefore, those skilled in the art have provided a conveniently assembled HDPE double-wall corrugated pipe to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-assemble HDPE double-wall corrugated pipe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A conveniently assembled HDPE double-wall corrugated pipe includes a double-wall corrugated pipe body, a positioning and guiding structure, and an anti-detachment structure. The double-wall corrugated pipe body has connecting pipes fixedly connected to both ends, several positioning seats fixedly connected to the outer wall of the double-wall corrugated pipe body, a connecting sleeve sleeved between adjacent connecting pipes, two first movable grooves at both ends of the connecting sleeve, with a positioning and guiding structure inside each first movable groove, and two second movable grooves at both ends of the connecting sleeve, with an anti-detachment structure inside each second movable groove.

[0007] As a further embodiment of this utility model: the positioning and guiding structure includes a first guide rod, a first threaded rod, a first threaded sleeve and a snap-fit ​​block. The first movable groove is L-shaped, and the insertion positioning rod is inserted into the first movable groove. The first guide rod is fixedly connected inside the first movable groove, and the first threaded rod is rotatably connected inside the first movable groove. The first threaded rod is threadedly connected to the first threaded sleeve.

[0008] As a further embodiment of this utility model: a snap-fit ​​block is fixedly connected to one end of the first threaded sleeve, and plug-in positioning rods are fixedly connected to both ends of the double-walled corrugated pipe body and on both sides of the connecting pipe. The plug-in positioning rods have through grooves inside, and the snap-fit ​​block is adapted to the through grooves.

[0009] As a further embodiment of this utility model: the anti-detachment structure includes a second threaded rod, a second guide rod, a second threaded sleeve, a first movable block, and a linkage rod. The second threaded rod is rotatably connected inside the second movable groove, and the second guide rod is fixedly connected inside the second movable groove. The second threaded sleeve is threadedly connected to the second threaded rod, and the first movable block is fixedly connected to one end of the second threaded sleeve. The linkage rod is rotatably connected to the first movable block.

[0010] As a further embodiment of this utility model: two hinge seats are fixedly connected to both ends of the connecting sleeve, and a movable frame is rotatably connected to the hinge seats. A second movable block is fixedly connected to the end of the movable frame near the connecting sleeve. The end of the linkage rod away from the first movable block is connected to the second movable block. An abutment ball is fixedly connected to the end of the movable frame away from the hinge seats. A groove adapted to the abutment ball is opened at the end of the positioning seat away from the main body of the double-walled corrugated pipe.

[0011] As a further embodiment of this utility model: a first bevel gear is fixedly connected to the first threaded rod, and a turntable is fixedly connected to one end of the first threaded rod through the connecting sleeve; a second bevel gear is fixedly connected to one end of the second threaded rod through the first movable groove, and the first bevel gear and the second bevel gear are meshed together.

[0012] As a further embodiment of this utility model: a second groove is provided on the inner side wall of the connecting sleeve, a second sealing ring is installed inside the second groove, and the second sealing ring is placed between two adjacent connecting pipes. A first groove is provided on both sides of the second groove on the inner side wall of the connecting sleeve, and a first sealing ring is installed inside the first groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This device completes the initial connection operation of the double-wall corrugated pipe body in the connecting sleeve through the setting of the positioning guide structure. After the insertion positioning rod is inserted into the first movable groove, the turntable is rotated to drive the first threaded rod to rotate, which in turn drives the first threaded sleeve and the snap-fit ​​block to move, and then drives the snap-fit ​​block to gradually insert into the through groove inside the insertion positioning rod, realizing the initial positioning of the two double-wall corrugated pipe bodies in the connecting sleeve, ensuring the accuracy of the connection of the pipes and ensuring the consistency of the pipe axis;

[0015] 2. This device uses an anti-detachment structure to firmly fix the connecting pipe to the connecting sleeve. When the first threaded rod rotates, the meshing of the first and second bevel gears drives the second threaded rod to rotate, which in turn drives the second threaded sleeve and the first movable block to move. The first movable block drives the movable frame to rotate around the hinge seat as the fulcrum through the linkage rod. As the movable frame rotates, the abutment ball gradually gets into the groove on the positioning seat, firmly fixing the connecting pipe inside the connecting sleeve. This prevents the double-wall corrugated pipe body from detaching from the connecting sleeve due to external forces during use, greatly enhancing the stability of the connection. When the pipeline is subjected to axial tension, water flow impact, or external forces generated by foundation settlement, the tight fit between the abutment ball and the groove can effectively prevent the double-wall corrugated pipe body from separating from the connecting sleeve. When maintenance or repair of the pipeline is required, simply rotate the turntable in the opposite direction to release the fixed state of the anti-detachment structure and the positioning guide structure in sequence, making it convenient and quick to disassemble the double-wall corrugated pipe.

[0016] 3. The first and second grooves on the inner sidewall of the connecting sleeve of this device are respectively equipped with a first sealing ring and a second sealing ring. When the connecting pipe of the two double-wall corrugated pipe bodies is inserted into the connecting sleeve, the first sealing ring is tightly fitted between the connecting pipe and the sidewall of the connecting sleeve, and the second sealing ring is located at the joint of the two adjacent connecting pipes. These sealing rings play a good sealing role, effectively preventing the medium from leaking from the joint, and ensuring the sealing performance and integrity of the HDPE double-wall corrugated pipe system.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Refer to Figure 1-5 This embodiment provides a conveniently assembled HDPE double-wall corrugated pipe, including a double-wall corrugated pipe body 1, a positioning and guiding structure, and an anti-detachment structure. The double-wall corrugated pipe body 1 has connecting pipes 2 fixedly connected to both ends, several positioning seats 5 fixedly connected to the outer wall of the double-wall corrugated pipe body 1, a connecting sleeve 6 sleeved between two adjacent connecting pipes 2, two first movable grooves 7 being provided at both ends of the connecting sleeve 6, and a positioning and guiding structure being provided inside the first movable grooves 7; and two second movable grooves 13 being provided at both ends of the connecting sleeve 6, and an anti-detachment structure being provided inside the second movable grooves 13.

[0027] The positioning and guiding structure includes a first guide rod 8, a first threaded rod 9, a first threaded sleeve 11, and a snap-fit ​​block 12. The first movable groove 7 is L-shaped, and the insertion positioning rod 3 is inserted into the first movable groove 7. The first guide rod 8 is fixedly connected inside the first movable groove 7. The first threaded rod 9 is rotatably connected inside the first movable groove 7, and the first threaded sleeve 11 is threadedly connected to the first threaded rod 9. The snap-fit ​​block 12 is fixedly connected to one end of the first threaded sleeve 11. The insertion positioning rod 3 is fixedly connected to both ends of the double-walled corrugated pipe body 1 and to both sides of the connecting pipe 2. The insertion positioning rod 3 has a through groove 4 inside, and the snap-fit ​​block 12 is adapted to the through groove 4.

[0028] In this implementation, when assembling two HDPE double-wall corrugated pipe bodies, first, the connecting sleeve 6 is fitted onto the end of one of the double-wall corrugated pipe bodies 1 with the connecting pipe 2. At this time, the insertion positioning rod 3 on the double-wall corrugated pipe body 1 is aligned with the first movable groove 7 at the end of the connecting sleeve 6, preparing for subsequent positioning guidance. Next, the connecting pipe 2 of the other double-wall corrugated pipe body 1 is inserted into the other end of the connecting sleeve 6, so that the connecting pipes 2 of the two double-wall corrugated pipe bodies 1 are connected inside the connecting sleeve 6. After the insertion positioning rod 3 is inserted into the first movable groove 7, the first threaded rod 9 is rotated. The turntable 24 is fixedly connected, and the first threaded rod 9 rotates accordingly. Since the first threaded rod 9 is threadedly connected to the first threaded sleeve 11, the first threaded sleeve 11 will move under the guidance of the first guide rod 8. As the first threaded sleeve 11 moves, the snap-fit ​​block 12 fixed at one end is gradually inserted into the through groove 4 inside the insertion positioning rod 3. In this way, the initial positioning of the two double-wall corrugated pipe bodies 1 in the connecting sleeve 6 is achieved, ensuring the accuracy of the connection of the connecting pipe 2, ensuring the consistency of the pipe axis, and also providing a stable foundation for subsequent anti-detachment operations.

[0029] Example 2: Refer to Figure 1-7 This embodiment is based on the previous embodiment, but differs in that the anti-detachment structure includes a second threaded rod 14, a second guide rod 16, a second threaded sleeve 17, a first movable block 18, and a linkage rod 19. The second threaded rod 14 is rotatably connected inside the second movable groove 13, and the second guide rod 16 is fixedly connected inside the second movable groove 13. The second threaded sleeve 17 is threadedly connected to the second threaded rod 14. The first movable block 18 is fixedly connected to one end of the second threaded sleeve 17. The linkage rod 19 is rotatably connected to the first movable block 18. Two hinge seats 20 are fixedly connected to both ends of the connecting sleeve 6. The hinge seats 20 are rotatably connected to a movable frame 21. The movable frame 21 is fixedly connected to a second movable block 22 at the end near the connecting sleeve 6. The linkage rod 19 is connected to the second movable block 22 at the end away from the first movable block 18. The abutment ball 23 is fixedly connected to the end of the movable frame 21 away from the hinge seat 20. The positioning seat 5 has a groove adapted to the abutment ball 23 at the end away from the double-walled corrugated pipe body 1.

[0030] A first bevel gear 10 is fixedly connected to the first threaded rod 9, and a turntable 24 is fixedly connected to one end of the first threaded rod 9 through the connecting sleeve 6. A second bevel gear 15 is fixedly connected to one end of the second threaded rod 14 through the first movable groove 7, and the first bevel gear 10 and the second bevel gear 15 are meshed together.

[0031] A second groove 26 is provided on the inner side wall of the connecting sleeve 6. A second sealing ring 28 is installed inside the second groove 26 and is placed between two adjacent connecting pipes 2. A first groove 25 is provided on the inner side wall of the connecting sleeve 6 on both sides of the second groove 26 and a first sealing ring 27 is installed inside the first groove 25.

[0032] In this embodiment, while the first threaded rod 9 rotates, the first bevel gear 10 meshes with the second bevel gear 15, causing the first bevel gear 10 to drive the second bevel gear 15 to rotate, which in turn causes the second threaded rod 14 to rotate. When the second threaded rod 14 rotates, the second threaded sleeve 17, which is threadedly connected to it, moves under the guidance of the second guide rod 16. The second threaded sleeve 17 drives the first movable block 18 to move. The first movable block 18, through the linkage rod 19, drives the movable frame 21 to rotate around the hinge seat 20 as a fulcrum. As the movable frame 21 rotates, the fixed... The abutment ball 23 at its end gradually engages with the groove on the positioning seat 5, tightly fixing the connecting pipe 2 inside the connecting sleeve 6. This prevents the double-wall corrugated pipe body from separating from the connecting sleeve due to external forces during use, greatly enhancing the stability of the connection. When the pipe is subjected to axial tension, water flow impact, or external forces generated by foundation settlement, the tight fit between the abutment ball 23 and the groove effectively prevents the separation of the double-wall corrugated pipe body 1 from the connecting sleeve 6. During the initial positioning by rotating the first threaded rod 9, the first bevel gear 10 and the second bevel gear 15... The meshing mechanism simultaneously drives the anti-detachment structure, eliminating the need for additional operating steps or a drive source. Construction personnel only need to operate the turntable 24 to simultaneously complete positioning and anti-detachment fixing, greatly improving installation efficiency. Compared to traditional connection methods requiring step-by-step operations, this saves significant time and labor costs. Furthermore, when pipeline maintenance or repair is required, simply rotating the turntable 24 in the reverse direction releases the anti-detachment structure and positioning guide structure sequentially, facilitating quick and easy disassembly of the double-wall corrugated pipe. Compared to some complex, non-removable, or difficult-to-remove connection structures, this design significantly shortens maintenance time. The first groove 25 and the second groove 26 on the inner wall of the connecting sleeve 6 are respectively fitted with a first sealing ring 27 and a second sealing ring 28. When the connecting pipe 2 of the two double-wall corrugated pipe bodies is inserted into the connecting sleeve 6, the first sealing ring 27 tightly fits between the connecting pipe 2 and the side wall of the connecting sleeve 6, while the second sealing ring 28 is located at the joint of two adjacent connecting pipes 2. These sealing rings provide excellent sealing, effectively preventing media leakage from the connection point and ensuring the sealing and integrity of the HDPE double-wall corrugated pipe system.
