Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, specifically a PVC drainage pipe with a noise reduction mechanism. Background Technology

[0002] As an essential structure of buildings, drainage pipes are crucial for ensuring smooth drainage. Currently, the most common drainage pipes in buildings on the market are vertical pipes and horizontal pipes. Vertical pipes are usually the main channels, while horizontal pipes are usually branches of the channels, used to connect the main channels and drainage ends. That is, multiple drainage ends are connected to the vertical pipes through corresponding horizontal pipes to achieve the discharge of water after collection.

[0003] Existing drainage pipes lack any noise reduction structure inside, requiring more external space to achieve the same sound insulation effect. This poses significant installation in confined spaces and necessitates complete replacement for maintenance, resulting in high costs and cumbersome operations. Therefore, we propose a PVC drainage pipe with an integrated noise reduction mechanism. Utility Model Content

[0004] The existing drainage pipes lack any noise reduction structure, resulting in significant inconvenience during installation and requiring complete replacement for subsequent maintenance, which is costly and cumbersome. This invention addresses these shortcomings by providing a PVC drainage pipe with a noise reduction mechanism. This allows for the rapid installation of a first and second arc-shaped plate, effectively reducing noise while improving the device's practicality, thus solving the problems mentioned in the background section.

[0005] The technical solution of this utility model is implemented as follows: A PVC drainage pipe with a noise reduction mechanism includes a first arc plate and a second arc plate symmetrically arranged on the outer wall of the drainage pipe. A buffer layer and a sound-absorbing layer are arranged inside the first arc plate and the second arc plate. Multiple slots are symmetrically arranged at the end of the first arc plate, and multiple connecting rods are symmetrically arranged at the end of the second arc plate. A V-shaped block is fixedly connected to the end of the connecting rod, and the V-shaped block is snapped into the slot.

[0006] Optionally, a cavity is provided on the side of the first arc-shaped plate and the second arc-shaped plate near the drain pipe, and the buffer layer and the sound-absorbing layer are distributed in sequence from the inside to the outside of the cavity.

[0007] Optionally, multiple arc-shaped seats are connected to the side of the buffer layer away from the sound-absorbing layer, and an arc-shaped baffle is connected to the end of the arc-shaped seats, with the arc-shaped baffle abutting against the inner wall of the cavity.

[0008] Optionally, the buffer layer, the arc-shaped seat, and the arc-shaped baffle are all made of rubber.

[0009] Optionally, the buffer layer, arc-shaped seat, and arc-shaped baffle are integrally molded structures.

[0010] Optionally, the sound-absorbing layer is a sound-absorbing cotton layer.

[0011] Optionally, an arc-shaped groove is provided on one end of the first arc-shaped plate and the second arc-shaped plate, and an L-shaped groove is provided at the top of the arc-shaped groove. An L-shaped block is tightly attached to one end of the first arc-shaped plate and the second arc-shaped plate.

[0012] Compared with the prior art, this utility model achieves rapid installation of the first and second arc-shaped plates by symmetrically wrapping the first and second arc-shaped plates around the outer wall of the drain pipe and pressing them down. Under the pressure, the V-shaped block snaps into the slot, thus achieving rapid installation of the first and second arc-shaped plates. The bottom of the L-shaped block slides in the arc-shaped groove, thereby achieving the snapping of the L-shaped block in the L-shaped groove and arc-shaped groove. This effectively improves the connection stability of multiple sets of first and second arc-shaped plates, not only effectively reducing noise but also improving the practicality of the device.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 6 This utility model provides a technical solution: a PVC drainage pipe with a noise reduction mechanism, including a first arc-shaped plate 3 and a second arc-shaped plate 4 symmetrically arranged on the outer wall of the drainage pipe 1. To ensure the overall noise reduction function of the drainage pipe 1, a buffer layer 10 and a sound-absorbing layer 7 are provided inside the first arc-shaped plate 3 and the second arc-shaped plate 4. In actual use, such as... Figure 4 , 5 As shown, a cavity 5 is provided on the side of the first arc plate 3 and the second arc plate 4 near the drain pipe 1, and the buffer layer 10 and the sound-absorbing layer 7 are distributed from the inside to the outside in the cavity 5.

[0023] Meanwhile, to improve the stability of the surface connection between the sound-absorbing layer 7 and the drain pipe 1 and ensure normal sound absorption effect, multiple arc-shaped seats 11 are connected to the side of the buffer layer 10 away from the sound-absorbing layer 7, and arc-shaped baffles 12 are connected to the ends of the arc-shaped seats 11. The arc-shaped baffles 12 abut against the inner wall of the chamber 5. When the first arc-shaped plate 3, the second arc-shaped plate 4 and the outer wall of the drain pipe 1 are connected, the sound-absorbing layer 7 abuts against the outer wall of the drain pipe 1. At the same time, to further improve the stability of the surface connection between the sound-absorbing layer 7 and the drain pipe 1, the buffer layer 10, the arc-shaped seats 11, and the arc-shaped baffles 12 are all rubber plates. The buffer layer 10, the arc-shaped seats 11, and the arc-shaped baffles 12 are integrally formed structures, and the sound-absorbing layer 7 is a sound-absorbing cotton layer, which greatly improves the sound absorption effect.

[0024] In summary, when using this PVC drainage pipe with a noise reduction mechanism, the required number of first arc-shaped plates 3 and second arc-shaped plates 4 are selected according to the length of the drainage pipe 1 to be installed. Multiple slots 9 are symmetrically arranged at the end of the first arc-shaped plate 3, and multiple connecting rods 13 are symmetrically arranged at the end of the second arc-shaped plate 4. A V-shaped block 8 is fixedly connected to the end of the connecting rod 13. During installation, the first arc-shaped plates 3 and second arc-shaped plates 4 are symmetrically wrapped around the outer wall of the drainage pipe 1, and the first arc-shaped plates 3 and second arc-shaped plates 4 are pressed. Under the action of pressure, the V-shaped block 8 is engaged in the slot 9, which can realize the quick installation of the first arc-shaped plates 3 and second arc-shaped plates 4. Furthermore, the sound-absorbing layer 7 abuts against the drainage pipe 1, which can prevent the first arc-shaped plates 3 and second arc-shaped plates 4 from slipping off the outer wall of the drainage pipe 1.

[0025] like Figure 2 , 3 As shown in Figures 1 and 4, to improve the stable connection between multiple sets of first arc-shaped plates 3 and second arc-shaped plates 4, arc-shaped grooves 14 are provided on one end of each of the first arc-shaped plates 3 and second arc-shaped plates 4. An L-shaped groove 2 is connected to the top of the arc-shaped groove 14. An L-shaped block 6 is fastened to one end of each of the first arc-shaped plates 3 and second arc-shaped plates 4. During installation, the L-shaped block 6 located on the upper layer is inserted into the L-shaped groove, and the first arc-shaped plates 3 and second arc-shaped plates 4 on the upper and lower layers are rotated. This allows the bottom of the L-shaped block 6 to slide within the arc-shaped groove 14, thereby achieving the locking of the L-shaped block 6 within the L-shaped groove 2 and arc-shaped groove 14. This effectively improves the connection stability of multiple sets of first arc-shaped plates 3 and second arc-shaped plates 4. This utility model not only effectively reduces noise in the drain pipe 1, but also facilitates the installation and disassembly of the device by the user, greatly improving the user's convenience and enhancing the practicality of the device.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
