Description

Technical Field

[0001] This application relates to the field of building wall technology, specifically to a soundproof wall panel. Background Technology

[0002] Soundproof wall panels are building materials specifically designed to block the transmission of sound. They are installed on walls to reduce the transmission of sound from one space to another, and are widely used in residential buildings, entertainment venues, construction sites, and factories. In the current technology, the sound insulation materials used in soundproof wall panels generally include high-density sound insulation cotton boards, sound insulation felt, polyester fiber sound insulation boards, expanded clay / foamed cement sound insulation boards, and wood / metal micro-perforated boards. These different materials typically correspond to different application scenarios with different sound insulation requirements.

[0003] Currently, in production plants, large-area, high-density sound insulation cotton boards are commonly used as sound insulation wall panels. However, these sound insulation cotton boards need to be installed piece by piece on-site, which is a rather tedious process. During installation, gaps with low density are likely to exist between adjacent sound insulation cotton boards, especially when the adjacent sound insulation cotton boards are at an angle. These gaps are particularly noticeable, and noise can easily pass through them, resulting in a significant decrease in the overall sound insulation effect. Summary of the Invention

[0004] To address the aforementioned deficiencies in existing technologies, this application provides a soundproof wall panel that simplifies the installation process, improves sound insulation, and has strong practicality.

[0005] To achieve the above objectives, the present invention employs the following techniques:

[0006] A soundproof wall panel, comprising:

[0007] The fixed plate consists of multiple pieces arranged parallel to each other in the height direction;

[0008] The sound insulation cotton board consists of multiple pieces that match the number of fixed plates, and each sound insulation cotton board and its corresponding fixed plate is vertically connected by a fixed post;

[0009] The movable strips are provided at both ends of the upper and lower ends of each fixed plate. The length direction of each movable strip is parallel to the length direction of the upper and lower ends of the fixed plate, and each movable strip is moved along the length direction of the upper and lower ends of the fixed plate. One end of each movable strip extends out of the fixed plate.

[0010] The rotating plate consists of multiple plates respectively located between two adjacent fixed plates. The height direction of the rotating plate is parallel to the height direction of the fixed plate. The two ends of the upper surface and the two ends of the lower surface of the rotating plate are rotatably connected to the ends of the four moving strips on both sides of the rotating plate that extend out of the fixed plate. The rotation axes of the two moving strips located on the same side of the rotating plate are coaxially set and parallel to the height direction of the fixed plate.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. By pre-connecting multiple sound insulation cotton panels to the rotating plate via a fixed plate, installation is more convenient as there is no need to install them one by one.

[0013] 2. By moving the fixed plate and the movable strip relative to each other, the spacing between adjacent sound insulation cotton boards can be freely adjusted, thereby increasing the density of the gap layer between adjacent sound insulation cotton boards and improving the sound insulation effect of the entire sound insulation wall panel.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0026] like Figure 1 As shown, this embodiment provides a soundproof wall panel, including a fixed plate 1, a soundproof cotton plate 2, a movable strip 3, a rotating plate 4, etc.

[0027] Specifically, such as Figure 1 As shown, the fixing plate 1 is rectangular and has multiple pieces arranged parallel to each other in the height direction. In this example, a total of four fixing plates 1 are provided.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the sound insulation cotton board 2 is rectangular and there are multiple boards matching the number of fixed boards 1. In this example, four sound insulation cotton boards 2 are provided. The sound insulation cotton boards 2 correspond one-to-one with the fixed boards 1, and each sound insulation cotton board 2 and its corresponding fixed board 1 is vertically connected by a fixing post 21. In this example, each sound insulation cotton board 2 and its corresponding fixed board 1 are vertically connected by four fixing posts 21, which are used to support the sound insulation cotton board 2.

[0029] Specifically, such as Figure 1 As shown, there are multiple movable strips 3 respectively located at both ends of the upper end face and both ends of the lower end face of each fixed plate 1. The length direction of each movable strip 3 is parallel to the length direction of the upper and lower end faces of the fixed plate 1, and each movable strip 3 is moved along the length direction of the upper and lower end faces of the fixed plate 1. One end of each movable strip 3 extends out of the fixed plate 1. More specifically, the cross-section of each movable strip 3 is rectangular, and the lower surface of the movable strip 3 is in sliding contact with the fixed plate 1.

[0030] Specifically, such as Figure 1As shown, the rotating plate 4 is a rectangular strip, and there are multiple rotating plates 4 respectively disposed between two adjacent fixed plates 1. That is, in this example, there are a total of three rotating plates 4. The height direction of the rotating plates 4 is parallel to the height direction of the fixed plates 1, and the two ends of the upper end face and the two ends of the lower end face of the rotating plate 4 are respectively rotatably connected to the ends of the four moving strips 3 on both sides of the rotating plate 4 that extend out of the fixed plates 1. Taking one rotating plate 4 as an example, the right end of the upper end face of the rotating plate 4 is rotatably connected to the end of the moving strip 3 extending out of the fixed plate 1 on the left end of the upper end face of the fixed plate 1 on the right side of the rotating plate 4. One end of the upper left side of the plate 4 is rotatably connected to one end of the moving strip 3 extending out of the fixed plate 1 on the upper right side of the fixed plate 1 on the left side of the rotating plate 4; one end of the lower right side of the rotating plate 4 is connected to one end of the moving strip 3 extending out of the fixed plate 1 on the lower left side of the fixed plate 1 on the right side of the rotating plate 4; one end of the lower left side of the rotating plate 4 is rotatably connected to one end of the moving strip 3 extending out of the fixed plate 1 on the lower right side of the fixed plate 1 on the left side of the rotating plate 4; the rotation axes of the two moving strips 3 located on the same side of the rotating plate 4 are coaxially arranged and parallel to the height direction of the fixed plate 1.

[0031] During operation, when the soundproof wall panel is moved, the relative movement of the moving strip 3 and the fixed plate 1 can adjust the distance between the fixed plate 1 and the corresponding rotating plate 4, increasing the distance between adjacent fixed plates 1 and rotating plates 4, thereby allowing the soundproof wall panel to be positioned as follows: Figure 3 The soundproof wall panel is transported in the folded state shown. At this time, the fixed plate 1 and the sound insulation cotton board 2 are parallel to each other, and the rotating plate 4 is perpendicular to the fixed plates 1 on both sides. This design can reduce the volume of the soundproof wall panel during transportation and can also protect most of the surface of the sound insulation cotton board 2 from damage during transportation by the fixed plate 1 and the rotating plate 4.

[0032] When installing this soundproof wall panel, unfold it from its folded state as follows: Figure 1 The flattened state shown is such that the surfaces of all fixed plates 1 and rotating plates 4 are parallel to each other. Then, by adjusting the distance between the fixed plates 1 and the corresponding rotating plates 4, the distance between the fixed plates 1 and the corresponding rotating plates 4 is reduced, thereby reducing the distance between adjacent sound insulation cotton plates 2 and bringing them into contact, and compressing their contact edges. At this point, the sound insulation wall panel is in the state shown. Figure 4 As shown, this increases the density of the contact edges of adjacent sound insulation cotton boards 2, preventing noise from passing through the gap layer between adjacent sound insulation cotton boards 2 and improving the sound insulation effect.

[0033] When an angle is required between two adjacent sound insulation cotton panels 2, the moving strip 3 is rotated on the rotating plate 4, and the distance between the adjacent fixed plate 1 and the corresponding rotating plate 4 is adjusted simultaneously, so that the two adjacent sound insulation cotton panels 2 are at an angle. Figure 5 The close contact shown can also improve sound insulation.

[0034] Once set up, the fixing plate 1 can be installed on the corresponding wall or on the corresponding mounting bracket. This design avoids the large amount of time spent on alignment and correction steps when installing each sound insulation cotton board 2 individually, simplifying the installation process.

[0035] Preferred, such as Figure 1 and Figure 6 As shown, each of the sound insulation cotton panels 2 has a first mounting chamber 22 on the side facing away from the fixed plate 1. Each first mounting chamber 22 contains a mounting plate 23 with its surface parallel to the fixed plate 1. Each mounting plate 23 has a second mounting chamber 24 on the side facing away from the fixed plate 1. Each second mounting chamber 24 contains a sound-absorbing plate 25 with its surface parallel to the fixed plate 1. With this design, although high-density sound insulation cotton panels 2 are used, adjacent sound insulation cotton panels 2 are still prone to deformation or breakage when compressed. Therefore, a rigid mounting plate 23 is placed in the first mounting chamber 22 to support the sound insulation cotton panels 2 and prevent deformation or breakage during compression. Simultaneously, since the sound insulation cotton panels 2 only serve a sound insulation function, a rigid sound-absorbing plate 25 is also provided. The sound-absorbing plate 25 can be a conventional perforated plate to reduce the noise impact on factory workers working inside the sound insulation wall panel.

[0036] Preferred, such as Figure 7 As shown, the four sides of the sound-absorbing panel 25 are respectively installed on the four inner sides of the second mounting chamber 24, and there is a gap between the sound-absorbing panel 25 and the inner bottom surface of the second mounting chamber 24. This design can further improve the sound absorption effect of the sound-absorbing panel 25. More preferably, a certain amount of low-density soft sound-absorbing cotton can be filled between the sound-absorbing panel 25 and the inner bottom surface of the second mounting chamber 24 to further improve the sound insulation effect.

[0037] Preferred, such as Figure 6 As shown, a first vibration damping sleeve 26 is fitted on each side of the sound-absorbing panel 25. The first vibration damping sleeve 26 is installed on the inner side of the second mounting chamber 24. The first vibration damping sleeve 26 can be made of conventional soft rubber material to reduce the noise generated by the vibration of the hard sound-absorbing panel 25 itself.

[0038] Preferred, such as Figure 8 As shown, each sound insulation cotton board 2 has an installation port 27 that runs through it in a direction perpendicular to its own surface. The installation port 27 runs from the side of the sound insulation cotton board 2 facing the fixing plate 1 to the inner bottom surface of the first installation chamber 22. The fixing column 21 is vertically connected to the fixing plate 1 and the installation plate 23 through the installation port 27. With this design, the rigid installation plate 23 can be directly installed on the fixing plate 1.

[0039] Preferred, such as Figure 8As shown, each of the fixed columns 21 has a cylindrical opening 28 coaxially opened inward at one end near the fixed plate 1. A second damping sleeve 29 is coaxially installed on the inner wall of each cylindrical opening 28. A connecting column 210 is coaxially installed on the inner wall of each second damping sleeve 29. The connecting column 210 is vertically connected to the corresponding fixed plate 1. The second damping sleeve 29 can be made of conventional soft rubber material.

[0040] With this design, since the sound-absorbing panel 25, mounting plate 23, fixing column 21, and fixing plate 1 are all rigid materials that easily transmit sound, some noise can easily be transmitted through the sound-absorbing panel 25, mounting plate 23, and fixing column 21 to the fixing plate 1, and then to the mounting surface of the soundproof wall panel, greatly reducing the sound insulation effect. Therefore, this embodiment provides a first vibration damping sleeve 26 and a second vibration damping sleeve 29. The first vibration damping sleeve 26 is used to reduce the transmission of noise between the sound-absorbing panel 25 and the mounting plate 23, and the second vibration damping sleeve 29 is used to further reduce the transmission of noise between the fixing column 21 and the fixing plate 1, thereby improving the sound insulation effect. The principle of reducing noise transmission by reducing vibration is existing technology and will not be elaborated here.

[0041] Preferred, such as Figure 9 As shown, each rotating plate 4 includes two rotating sub-plates 41. The upper and lower ends of each rotating sub-plate 41 are respectively rotatably connected to two moving strips 3 on the same side of the corresponding fixed plate 1. The two rotating sub-plates 41 belonging to the same rotating plate 4 are connected by studs.

[0042] With this design, although only four sound insulation cotton boards 2 are shown in this embodiment, the sound insulation cotton boards 2 can be easily added or removed by merging or separating the auxiliary plate 41 with studs, so as to expand the application scenarios of the sound insulation wall panel.

[0043] Preferred, such as Figure 10 As shown, fixing blocks 11 are provided at both ends of the upper and lower ends of the fixing plate 1. Screws 12 are threaded through the fixing blocks 11 on the upper end of the fixing plate 1 and are threadedly engaged with the screws 12. The screws 12 are parallel to the length direction of the upper end of the fixing plate 1, and one end of each screw 12 is rotatably connected to the corresponding moving bar 3. Each screw 12 is rotatably arranged around its own central axis. Sliding rods 13 are slidably engaged with the fixing blocks 11 on the lower end of the fixing plate 1. The sliding rods 13 are parallel to the length direction of the lower end of the fixing plate 1, and one end of each sliding rod 13 is rotatably connected to the corresponding moving bar 3. With this design, the relative movement of the fixing plate 1 and the moving bar 3 can be driven by rotating the screws 12.

[0044] Preferred, such as Figure 10As shown, each fixing plate 1 has two bearing strips 14 on the side facing away from the sound insulation cotton board 2. The other ends of the two screws 12 on the fixing plate 1 are rotatably connected to the upper ends of the two bearing strips 14. Each bearing strip 14 has a rotating head 15 rotatably connected to the screw 12 on the upper end. The other ends of the two sliding rods 13 on the fixing plate 1 are connected to the lower ends of the two bearing strips 14. With this design, the corresponding screw 12 can be driven to rotate by rotating the rotating head 15 with an auxiliary tool such as an electric wrench.

[0045] Preferred, such as Figure 10 As shown, it also includes a track 5 for mounting on a mounting surface, which can be a wall or a mounting bracket, as long as the track 5 is horizontal; each of the bearing bars 14 has a loading block 16 in the middle, and each loading block 16 is rotatably connected to a roller 17. In this example, two rollers 17 are installed on one loading block 16; the rotation axis of each roller 17 is perpendicular to the fixed plate 1, and each roller 17 is used to roll with the track 5.

[0046] This design eliminates the need to pre-adjust the distance between the fixed plate 1 and the corresponding rotating plate 4. The track 5 can be directly installed on the mounting surface first, and then the multiple sound insulation cotton panels 2 in their unfolded state can be hung on the track 5. Subsequently, the distance between the fixed plate 1 and the corresponding rotating plate 4 can be directly adjusted on the track 5. This not only facilitates the installation and disassembly of the sound insulation cotton panels 2, but also allows the position of the sound insulation cotton panels 2 to be moved according to the needs of the site, further simplifying the installation steps of the sound insulation wall panel.

[0047] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
