Description

Technical Field

[0001] This utility model belongs to the field of sound insulation devices for drainage pipes, specifically, it relates to a sound insulation sleeve for residential water supply and drainage pipes that can reduce the transmission of pipe noise. Background Technology

[0002] Residential drainage pipes are specialized structures used to discharge sewage from indoor bathrooms, kitchens, and balconies, as well as collect rainwater from roofs. They are mainly made of materials such as PVC and cast iron.

[0003] Chinese patent CN219571234U discloses a pipe sound insulation structure with a wrapping structure, including a pipe body and a limiting wrapping assembly. The limiting wrapping assembly is disposed outside the second sound insulation cotton interlayer and includes a smooth protective inner plate, a supporting wrapping plate, and a smooth protective outer plate. A connecting shell is provided on the outside of the smooth protective outer plate, and a connecting protrusion is provided on the upper left side of the connecting shell. A limiting screw passes through the interior of the connecting protrusion, and a limiting fastening ring is connected to one end of the limiting screw. This application achieves the connection and fixation of the pipe and the sound insulation assembly through the cooperation of the limiting screw and the limiting fastening ring. However, the above solution requires the use of tools such as wrenches to achieve installation, which means that during installation and subsequent disassembly and maintenance, operators need to rotate the limiting fastening ring for a long time, which is cumbersome and inefficient. Although there is a method of fixing with elastic rope in the prior art, elastic rope needs to be in a taut state for a long time during use, and long-term stress is prone to elastic fatigue, which can lead to breakage.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0018] By pulling the U-shaped push rod, the rotating plate rotates under the action of the push cylinder and the trapezoidal block, thereby releasing the fixation between the protrusion and the bearing block, and thus separating the lower connecting cylinder from the upper connecting cylinder.

Detailed Implementation

[0029] 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.

[0030] Please see Figure 1-5 As shown, this embodiment provides a soundproof sleeve for residential water supply and drainage pipes that can reduce the transmission of pipe noise, including:

[0031] The lower connecting cylinder 1 has an upper connecting cylinder 101 on its upper side. Both the lower connecting cylinder 1 and the upper connecting cylinder 101 have sound-insulating cotton 102 installed on their inner walls. The sound-insulating cotton 102 has a thickness of 10–50 mm and a density of 30–100 kg / m³. 3 The sound insulation performance is not less than 0.7dB, which enables the sound insulation cotton 102 to effectively block noise from inside the pipe and reduce the transmission of pipe noise. The side of the lower connecting cylinder 1 is equipped with four arc-shaped rotating rods 4.

[0032] Two protrusions 5 are respectively installed at one end of two of the arc-shaped rotating rods 4. Each of the other two arc-shaped rotating rods 4 has a bearing block 6 installed at one end near the protrusion 5. A U-shaped push rod 601 is elastically and slidably fitted onto the bearing block 6. Movable rods 602 are installed on the lower sides of both ends of the U-shaped push rod 601, and push cylinders 603 are rotatably fitted around the periphery of the movable rods 602. Arc-shaped limiting blocks 501 are installed on both sides of the protrusion 5.

[0033] Two rotating plates 7 are elastically and rotatably fitted within the bearing block 6. One end of the rotating plate 7 extends to the outside of the bearing block 6. An arc-shaped limiting groove 701 is provided at the end of the rotating plate 7 near the protrusion 5. The arc-shaped limiting block 501 is located in the arc-shaped limiting groove 701. A trapezoidal block 8 is installed on the side of the rotating plate 7 near the push cylinder 603.

[0034] One application of this embodiment is as follows: First, pull the U-shaped push rod 601, thereby driving the movable rod 602 and the push cylinder 603 to move. During the movement, the push cylinder 603 will gradually come into contact with the inclined surface of the trapezoidal block 8, and the trapezoidal block 8 will press the rotating plate 7, causing it to rotate around the central axis on the bearing block 6. This will cause the arc-shaped limiting groove 701 to disengage from the arc-shaped limiting block 501, releasing the fixed connection between the protrusion 5 and the bearing block 6. At this time, pulling the protrusion 5 and the bearing block 6 respectively will open them. Then, release the U-shaped push rod 601 so that it resets under the action of elasticity. Next, separate the lower connecting cylinder 1 and the upper connecting cylinder 101. The drain pipe is placed inside the lower connecting cylinder 1, and then the upper connecting cylinder 101 is placed back on the lower connecting cylinder 1. The U-shaped push rod 601 is then pulled again, causing the rotating plate 7 to rotate under the action of the push cylinder 603 and the trapezoidal block 8. The protrusion 5 and the bearing block 6 are then reset and re-attached to the upper connecting cylinder 101. At this point, the U-shaped push rod 601 is released, allowing it to reset under the action of the elastic force. This allows one end of the rotating plate 7 to be fitted onto the arc-shaped limiting block 501 using the arc-shaped limiting groove 701, achieving a fixed connection between the protrusion 5 and the bearing block 6, and simultaneously completing the clamping and fixing of the drain pipe. It should be noted that all electrical equipment involved in this application can be powered by a battery or an external power source.

[0035] By pulling the U-shaped push rod 601, the rotating plate 7 rotates under the action of the push cylinder 603 and the trapezoidal block 8, thereby releasing the fixation between the protrusion 5 and the bearing block 6, and thus separating the lower connecting cylinder 1 and the upper connecting cylinder 101. This operation reduces the use of tools and shortens the disassembly time. Furthermore, through the cooperation of the arc-shaped limiting block 501 and the arc-shaped limiting groove 701, the fixation between the protrusion 5 and the bearing block 6 can be achieved, realizing a quick locking effect and improving the convenience of installation.

[0036] Specifically, anti-slip pads 103 are installed on the inner side of both sound insulation cotton 102. The anti-slip pads 103 are made of rubber, with a thickness of 1-5mm and a static friction coefficient of not less than 0.8. This effectively increases the friction between the drainage pipe and the lower connecting cylinder 1 and the upper connecting cylinder 101, reducing the probability of the drainage pipe moving. By setting the anti-slip pads 103, the static friction coefficient between the drainage pipe and the structure is increased, making the drainage pipe less prone to movement and improving the stability of the drainage pipe after installation.

[0037] To enable the lower connecting cylinder 1 to connect with other equipment, its specific structure is as follows: Figure 1 As shown. The bottom of the lower connecting cylinder 1 is equipped with two connecting seats 104, and the lower rectangular array of the connecting seats 104 has four docking holes 105.

[0038] The lower connecting cylinder 1 can be connected to the wall or other equipment through the docking hole 105.

[0039] To ensure the smooth rotation of the arc-shaped rotating rod 4, its specific structure is as follows: Figure 2 and Figure 5 As shown. Connecting blocks 2 are installed on both sides of the connecting seat 104, and first connecting shafts 201 are installed on both sides of the connecting blocks 2. The two first connecting shafts 201 are rotatably engaged with the same U-shaped rotating rod 202, and the lower end of the arc-shaped rotating rod 4 is fixedly engaged with the U-shaped rotating rod 202.

[0040] With the cooperation of connecting block 2, first connecting shaft 201 and U-shaped rotating rod 202, not only is a connection provided between arc-shaped rotating rod 4 and lower connecting cylinder 1, but also the arc-shaped rotating rod 4 can rotate smoothly, so that the protrusion 5 and bearing block 6 can open or close smoothly.

[0041] To achieve positioning and alignment between the lower connecting cylinder 1 and the upper connecting cylinder 101, the specific structure is as follows: Figure 1 As shown. Two docking blocks 3 are symmetrically installed on the side of the upper connecting cylinder 101. An insert block 301 is installed on the lower side of the docking block 3. Two U-shaped positioning blocks 302 are symmetrically installed on the side of the lower connecting cylinder 1. The insert block 301 is snapped into the U-shaped positioning block 302.

[0042] When connecting the lower connecting cylinder 1 and the upper connecting cylinder 101, the lower connecting cylinder 1 and the upper connecting cylinder 101 can be positioned and aligned by inserting the insert block 301 on the docking block 3 into the U-shaped positioning block 302, so that the two are less likely to be misaligned, which provides convenience for subsequent operations.

[0043] To ensure that the U-shaped push rod 601 can smoothly perform its reset movement, its specific structure is as follows: Figure 2 , Figure 3 and Figure 4 As shown. A slider 604 is slidably fitted inside the bearing block 6. Both ends of the slider 604 are mounted on the U-shaped push rod 601. Two springs 605 are installed between the slider 604 and one side of the inner wall of the bearing block 6.

[0044] During the process of pulling the U-shaped push rod 601 to move the movable rod 602 and the push cylinder 603, the slider 604 will also move. At this time, the moving slider 604 can squeeze the spring 605, so that the spring 605 is in a taut state, thus providing power for the subsequent reset of the U-shaped push rod 601. When the U-shaped push rod 601 is released, the spring 605 can push the U-shaped push rod 601 to reset smoothly under its own elastic force.

[0045] To improve the stability of slider 604 during movement, its specific structure is as follows: Figure 3 and Figure 4 As shown. Two guide rods 606 are installed between the two sides of the inner wall of the bearing block 6. The guide rods 606 pass through the slider 604 laterally, and the spring 605 is located around the guide rods 606.

[0046] The guide rod 606 constrains the movement direction of the slider 604, making it less likely for the slider 604 to deviate and improving the stability of the slider 604 during movement.

[0047] Specifically, the support block 6 is provided with a sliding groove 607, and the slider 604 and spring 605 are both located in the sliding groove 607. The guide rod 606 is installed between the two sides of the sliding groove 607. Both sides of the sliding groove 607 are provided with movable grooves 608, which penetrate through the upper side of the support block 6. The middle parts of both ends of the U-shaped push rod 601 are respectively located in the two movable grooves 608. One side of the support block 6 is provided with a through groove 610 that communicates with the two movable grooves 608, and the through groove 610 penetrates the support block 6 laterally. Under the action of the sliding groove 607, movable grooves 608 and through groove 610, space is provided for the movement of the slider 604, U-shaped push rod 601 and push cylinder 603, enabling them to move smoothly.

[0048] To achieve the connection between the push cylinder 603 and the movable rod 602, its specific structure is as follows: Figure 2 and Figure 4 As shown. A bearing 609 is installed on the periphery of the movable rod 602, and the push cylinder 603 is sleeved on the periphery of the bearing 609.

[0049] Under the action of bearing 609, the rotational friction between push cylinder 603 and movable rod 602 can be reduced, so that push cylinder 603 can rotate smoothly after contacting trapezoidal block 8; and it can provide connection between push cylinder 603 and movable rod 602.

[0050] To ensure that the rotating plate 7 can smoothly rotate to its reset position, its specific structure is as follows: Figure 2 and Figure 3 As shown. The bearing block 6 is equipped with two second connecting shafts 9. The middle part of the rotating plate 7 is rotatably engaged with the periphery of the second connecting shaft 9. A torsion spring 901 is sleeved on the periphery of the second connecting shaft 9. One end of the torsion spring 901 is engaged in the second connecting shaft 9, and the other end is engaged in the inner wall side of the rotating plate 7. The second connecting shaft 9 is installed between the upper and lower sides of the through groove 610. The second connecting shaft 9 is located between the arc-shaped limiting groove 701 and the trapezoidal block 8.

[0051] When the pusher 603 is pressing the inclined surface of the trapezoidal block 8 and forcing the rotating plate 7 to rotate, the rotating plate 7 will drive the torsion spring 901 to undergo torsional deformation, thereby providing power for the subsequent rotation and reset of the rotating plate 7. When the U-shaped pusher 601 is released, the rotating plate 7 will be reset by the elastic force of the torsion spring 901, so that one end of the rotating plate 7 can be smoothly fitted onto the arc-shaped limiting block 501 using the arc-shaped limiting groove 701.

[0052] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
