Description

Technical Field

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

[0002] Drainage pipes are an important part of urban infrastructure, mainly responsible for collecting and transporting domestic sewage, industrial wastewater and rainwater, ensuring that these water flows are properly treated and discharged, thereby maintaining the balance of urban sanitation and environment. Silencing drainage pipes are a special drainage system, mainly used to reduce the noise generated during the drainage process.

[0003] Existing drainage pipes are not convenient for quick splicing of two pipes. When laying the pipes, workers need to use auxiliary tools to splice them, which reduces the efficiency of the workers. In addition, they do not have a sound-absorbing effect and are prone to generating noise during drainage, which reduces the comfort of living and working. Therefore, we propose a sound-absorbing drainage pipe to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a noise-absorbing drainage pipe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sound-absorbing drainage pipe includes a first pipe body and a second pipe body. A connector is provided on the right side of the first pipe body, and a connector is provided on the left side of the second pipe body. A rectangular groove is fixedly opened at the top and bottom of the connector. Limiting rods are fixedly connected to the left and right sides of the inner cavity of the rectangular groove. A limiting block is movably sleeved on the outer side of the limiting rod. A collar is fixedly connected to the top of the top limiting block and the bottom of the bottom limiting block. A sound-absorbing layer is provided in the inner cavity of both the first pipe body and the second pipe body.

[0007] Preferably, the right side of the connector extends into the inner cavity of the connector seat. Circular grooves are provided at the top and bottom of the connector. A limiting bead is placed in the inner cavity of the circular groove. The top of the limiting bead at the top and the bottom of the limiting bead at the bottom both penetrate the connector seat. Circular holes adapted to the limiting bead are provided at the top and bottom of the connector seat. One side of the limiting block contacts one side of the limiting bead.

[0008] Preferably, a first spring is fixedly connected to the right side of the limiting block, the right side of the first spring is fixedly connected to the right side of the inner cavity of the rectangular groove, the first spring is sleeved on the outside of the limiting rod, the outside of the limiting block is in sliding contact with the inner wall of the rectangular groove, and the inner cavity of the limiting block is in sliding contact with the outside of the limiting rod.

[0009] Preferably, the left side of the connector is fixedly connected to the right side of the first tube, the right side of the connector is fixedly connected to the left side of the second tube, and the inner walls of the first and second tubes are fixedly connected to the outer wall of the sound-absorbing layer.

[0010] Preferably, a sealing gasket is provided on the right side of the inner cavity of the connector, and the left side of the sealing gasket contacts the right side of the connector.

[0011] Preferably, the collar is movably sleeved on the outside of the connecting seat, and an anti-slip pad is fixedly embedded on the outside of the collar.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by holding the collar and sliding it to the right, the collar drives the limiting block to move to the right, so that the limiting block is away from the limiting bead. At the same time, the first spring is compressed. After the limiting block is away from the limiting bead, the first pipe body is pulled to the left. The first pipe body drives the connector to move to the left. The connector, through its interaction with the circular groove, will drive the top and bottom limiting beads to move into the inner cavity of the rectangular groove at the same time, so that the first pipe body and the second pipe body can be separated. This facilitates the quick splicing of the two pipes, avoids the need for auxiliary tools, and improves the installation efficiency of the workers.

[0014] 2. The sound-absorbing layer installed in the inner cavity of the first and second pipe bodies in this utility model has a certain sound-absorbing effect, which can reduce the sound of water flowing in the pipe and improve the comfort of living and working. Attached Figure Description

A sound-absorbing layer 5 is provided in the inner cavity of both the first pipe body 1 and the second pipe body 2.

[0021] In this embodiment, the right side of the connector 3 extends into the inner cavity of the connector seat 4. Circular grooves 15 are provided at both the top and bottom of the connector 3. Limiting beads 13 are placed in the inner cavity of the circular grooves 15. The top of the top limiting bead 13 and the bottom of the bottom limiting bead 13 both penetrate the connector seat 4. Circular holes 14 that are adapted to the limiting beads 13 are provided at both the top and bottom of the connector seat 4.

The outside of the limiting block 9 slides in contact with the inner wall of the rectangular groove 7. The inner cavity of the limiting block 9 slides in contact with the outside of the limiting rod 8. The limiting rod 8 can limit the limiting block 9, improving the stability of the left and right movement of the limiting block 9.

[0022] In this embodiment, the left side of the connector 3 is fixedly connected to the right side of the first tube 1, the right side of the connector 4 is fixedly connected to the left side of the second tube 2, the inner walls of the first tube 1 and the second tube 2 are fixedly connected to the outer wall of the sound-absorbing layer 5, a sealing gasket 6 is provided on the right side of the inner cavity of the connector 4, the left side of the sealing gasket 6 is in contact with the right side of the connector 3, the collar 10 is movably sleeved on the outside of the connector 4, and an anti-slip pad 12 is fixedly embedded on the outside of the collar 10. Through the sealing gasket 6, the connector 3 and the connector 4 can be sealed, thereby improving the sealing effect of the first tube 1 and the second tube 2.

[0023] In this embodiment, during use, by holding the collar 10 and sliding it to the right, the collar 10 drives the limiting block 9 to move to the right, moving the limiting block 9 away from the limiting bead 13, and simultaneously compressing the first spring 11. After the limiting block 9 moves away from the limiting bead 13, the first pipe body 1 is pulled to the left. The first pipe body 1 drives the connector 3 to move to the left. The connector 3, through its interaction with the circular groove 15, drives the top and bottom limiting beads 13 to move simultaneously into the inner cavity of the rectangular groove 7, thus separating the first pipe body 1 and the second pipe body 2. This facilitates quick splicing of the two pipes, avoiding the need for auxiliary tools and improving the installation efficiency of the workers. The sound-absorbing layer 5 installed in the inner cavity of the first pipe body 1 and the second pipe body 2 has a certain sound-absorbing effect, which can reduce the sound of water flowing in the pipes and improve the comfort of living and working.
