Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a quick-connect PE drainage pipe. Background Technology

[0002] Polyethylene (PE) drainage pipes are a common piping system used to discharge wastewater, sewage, and other liquids from buildings or other locations to sewage treatment facilities or other discharge points. Due to the advantages of polyethylene, such as corrosion resistance, chemical resistance, UV resistance, and durability, PE drainage pipes maintain stability under various environmental conditions, making them widely used in drainage systems of residential, commercial, and industrial buildings. Currently, most PE drainage pipes are connected by welding or insertion. While welding ensures the sealing of PE drainage pipes, it is inconvenient to install and disassemble. Conventional insertion connections rely solely on friction, making leaks prone to occur at the joints during use. Therefore, there is an urgent need for a quick-connect PE drainage pipe that is easy to install and disassemble and less prone to leaks. Utility Model Content

[0017] 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.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figure 1-4This utility model provides a quick-connect PE drain pipe, including a first drain pipe 1 and a second drain pipe 2. A rotating cylinder 3 is rotatably connected to the first drain pipe 1. One end of the first drain pipe 1 is located inside the rotating cylinder 3. One end of the second drain pipe 2 is located inside the rotating cylinder 3 and abuts against the first drain pipe 1. The end of the second drain pipe 2 located inside the rotating cylinder 3 is threadedly engaged with the inner wall of the rotating cylinder 3. An assembly ring 4 is fixedly connected to the end of the first drain pipe 1. The assembly ring 4 is located inside the second drain pipe 2. A limit component is installed between the assembly ring 4 and the inner wall of the second drain pipe 2.

[0020] The scheme is further optimized. The limiting component includes an annular groove 5 opened on the inner wall of the second drain pipe 2, the assembly ring 4 is slidably located in the annular groove 5, the side wall of the annular groove 5 is provided with a through hole 6, the limiting component is slidably connected in the through hole 6, and the assembly ring 4 is provided with an annular limiting groove 7 that is adapted to the limiting component.

[0021] The scheme is further optimized. The limiting component includes a moving block 8 that slides within the through hole 6. A sliding groove 9 is provided in the moving block 8. A sliding plate 10 is slidably connected within the sliding groove 9. A limiting block 11 is provided on the side of the moving block 8 near the annular limiting groove 7. The limiting block 11 is located within the annular limiting groove 7. A moving rod 12 is fixedly connected to the top surface of the limiting block 11. The top end of the moving rod 12 passes through the moving block 8 and is fixedly connected to the sliding plate 10. A first compression spring 13 is fixedly connected between the side of the sliding plate 10 away from the moving rod 12 and the inner wall of the sliding groove 9. A receiving groove 14 is provided in the second drain pipe 2 corresponding to the through hole 6. The through hole 6 passes through the receiving groove 14 and is connected to the receiving groove 14. A connecting plate 15 is slidably connected within the receiving groove 14. The connecting plate 15 is fixedly connected to the moving block 8. A second compression spring 16 is fixedly connected between the side of the connecting plate 15 near the limiting block 11 and the bottom wall of the receiving groove 14. A pressing component is installed at the end of the rotating drum 3 to drive the limiting block 11 to move into the annular limiting groove 7. The first compression spring 13 applies pressure to the slide plate 10, thereby buffering the limiting block 11, so that the limiting block 11 can contact the second drain pipe 2 and fall into the annular limiting groove 7 for locking during the downward movement of the moving block 8.

[0022] The design is further optimized. The pressing component includes a mounting ring 17 fixedly connected to the end face of the rotating cylinder 3. A gap is left between the inner wall of the mounting ring 17 and the outer wall of the second drain pipe 2. The top surface of the moving block 8 has an inclined surface, which faces the rotating cylinder 3. The inclined surface of the moving block 8 is located outside the through hole 6 and abuts against the mounting ring 17. During the screwing process, the mounting ring 17 contacts the top surface of the moving block 8 and presses the moving block 8 down, causing the limiting block 11 to contact the assembly ring 4 and fall into the annular limiting groove 7 for limiting.

[0023] The design is further optimized by creating a snap-fit ​​groove 18 on the inner wall of the mounting ring 17. The snap-fit ​​groove 18 is annular, and the top surface of the moving block 8 is located within it. A push plate 19 is slidably connected within the snap-fit ​​groove 18, corresponding to the moving block 8 and in contact with its top. A threaded rod 20 is rotatably connected to the side of the push plate 19 away from the moving block 8. The threaded rod 20 passes through the mounting ring 17 and is threadedly connected to it. A rotating nut 21 is fixedly connected to the outer end of the threaded rod 20 on the mounting ring 17. The snap-fit ​​groove 18 limits the movement of the moving block 8, preventing accidental rotation of the mounting ring 17 and ensuring its stability. When removal is required, simply rotate the rotating nut 21. This rotation pushes the push plate 19 downwards, releasing the moving block 8 from the snap-fit ​​groove 18, allowing the rotating drum 3 to be rotated for disassembly.

[0024] In a further optimized design, a sealing gasket 22 is fixedly connected inside the annular groove 5, and the sealing gasket 22 is positioned corresponding to the end face of the assembly ring 4. The sealing gasket 22 enables a seal between the assembly ring 4 and the second drain pipe 2.

[0025] The working process of this utility model is as follows: When in use, align the second drain pipe 2 with the inside of the rotating drum 3, and then rotate the rotating drum 3. Tighten the second drain pipe 2 through the threaded engagement, so that the second drain pipe 2 gradually approaches the first drain pipe 1. During the approach process, the mounting ring 17 presses down on the moving block 8, and the moving block 8 presses down on the limiting block 11 so that it contacts the top wall of the second drain pipe 2 and falls into the annular limiting groove 7 to achieve a snap-fit. At this time, the mounting ring 4 abuts against the sealing gasket 22 to achieve a connection. At the same time, the top of the moving block 8 falls into the snap-fit ​​groove 18, which can effectively prevent the mounting ring 17 from rotating under the action of external force and will not fall off automatically.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
