[0002] The wall-penetrating sleeve is also called the wall-penetrating pipe, waterproof sleeve, wall pre-buried pipe, and waterproof sleeve is divided into rigid waterproof sleeve and flexible waterproof sleeve. The two are mainly used in different places. The flexible waterproof sleeve is mainly used in places with high requirements such as civil air defense walls and pools. The rigid waterproof sleeve is generally used in basements and other places where pipes need to be passed through. At present, the wall-penetrating part of the wall-penetrating pipe used in buildings is surrounded by the floor or wall. When water flows through the water pipe, it will make a sound, and the noise generated needs to be reduced.

[0003] However, the existing noise reduction and silencing wall-penetrating pipes for water supply and drainage have the following disadvantages:

[0004] (1) When water flows through the drain pipe, the impact of the water flow may cause the drain pipe to shake, which may easily cause damage to the drain pipe;

[0005] (2) Existing drainage pipes are spliced ​​together with glue. The spliced ​​parts of the drainage pipes are corroded by water flow for a long time, which may cause water seepage.

[0006] Therefore, the utility model provides a noise-reducing and sound-absorbing wall-penetrating pipe for water supply and drainage. Utility Model Content

[0016] (III) Beneficial effects

[0017] The utility model provides a noise reduction and sound absorbing wall-penetrating pipe for water supply and drainage, which has the following beneficial effects:

[0018] 1. The noise reduction and silencing wall-penetrating pipe for water supply and drainage is provided with an A arc plate, bolts, bearings and a B arc plate. After the outer pipe is fixed, the staff rotates the bolts to move inward, and the movement of the bolts drives the B arc plate to move inward. Due to the inward force of the B arc plate, the B arc plate fixes the drainage pipe to avoid damage to the drainage pipe caused by shaking due to water flowing into the drainage pipe during drainage.

[0019] 2. The noise-reducing and sound-absorbing wall-penetrating pipe for water supply and drainage uses a circular clamp, a sealing ring and a rubber ring. Generally, glue is used to fix the joints of the drainage pipe. When used for a long time, it is easy for the water flow inside the drainage pipe to corrode the glue, causing water seepage. The sealing ring and the rubber ring can effectively prevent the water flow from corroding the joints, thereby increasing the service life of the drainage pipe and avoiding the occurrence of water seepage.

[0034] 2. After the outer tube 1 is fixed, the staff rotates the bolt 7 to move the bolt 7 inward, and the movement of the bolt 7 drives the B arc plate 8 to move inward. Due to the inward force of the B arc plate 8, the B arc plate 8 fixes the drain pipe 3, thereby preventing the drain pipe 3 from being damaged due to the shaking of the water flow during drainage;

[0035] 3. Finally, when the outer tube 1 needs to be spliced, the staff fits the B semicircular ring 12 with the A semicircular ring 11, and then rotates the limit bolt 16 so that the limit bolt 16 fixes the A semicircular ring 11 and the B semicircular ring 12.
