Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing panels, specifically a multi-layer board material. Background Technology

[0002] Sound-absorbing panels are an ideal sound-absorbing decorative material with multiple advantages such as sound absorption, environmental protection, and flame retardancy, and are widely used in various acoustic environments.

[0003] Existing sound-absorbing panels, such as the easily detachable sound-absorbing panel disclosed in CN219671928U, require locking blocks on both ends of the sound-absorbing panels for interconnection. However, this connection method prevents the locking blocks from being disassembled. Consequently, if the sound-absorbing panels need to be cut when installed on a wall, the locking blocks will be cut, preventing the sound-absorbing panels from being properly interconnected and reducing their efficiency. Therefore, we propose a multi-layer board material. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-layer board material, including a sound-absorbing board, wherein a second connecting component is installed at the rear end of the sound-absorbing board, and a first connecting component is installed between adjacent sound-absorbing boards, and mounting components are symmetrically arranged inside both ends of the sound-absorbing board. The first connecting component includes a connecting post. The sound-absorbing plate has symmetrically arranged insertion holes and second threaded holes inside the side walls at both ends. A threaded post is fixedly installed at the left end of the connecting post. The threaded post is threadedly connected to the inside of the second threaded hole. The right end of the connecting post is slidably connected to the inside of the insertion hole. The side walls of adjacent sound-absorbing plates are in contact with each other.

[0005] Preferably, the second connecting component includes a T-shaped plate, and the rear side wall of the sound-absorbing plate is provided with a T-shaped groove. The T-shaped plates are slidably connected to the inside of the T-shaped groove, and the length of each T-shaped plate is less than the length of the T-shaped groove. Both ends of the T-shaped groove are open.

[0006] Preferably, the second connecting assembly further includes a connecting rod. The two end sidewalls of the T-shaped plate are provided with connecting holes, and the interiors of the two connecting holes are connected to each other. The two ends of the connecting rod are slidably connected to the interiors of the connecting holes on one side of the adjacent sound-absorbing plate. The diameter of the connecting rod matches the diameter of the connecting hole, and the sidewall of the connecting rod is tightly fitted to the sidewall of the connecting hole, and there is friction. The outside of the connecting rod is fixedly fitted with a limiting piece, and the diameter of the limiting piece is smaller than the width of the T-shaped plate.

[0007] Preferably, the mounting assembly includes bolts, and mounting grooves are symmetrically arranged inside both ends of the sound-absorbing plate. Each mounting groove has a first threaded hole inside, and bolts are threaded into the first threaded holes. The diameter of the bolt nut matches the inner diameter of the mounting groove, and the diameter of the first threaded hole is smaller than the diameter of the mounting groove.

[0008] Preferably, the interior of each mounting groove is sealed with a sealing plug, the top sidewall of the sealing plug is horizontal to the top sidewall of the sound-absorbing plate, and the bottom of each sealing plug is attached to the top sidewall of the bolt.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figure 1 - Figure 4 This utility model discloses a multilayer board material, including a sound-absorbing board 1. A second connecting component 5 is installed at the rear end of the sound-absorbing board 1, and a first connecting component 4 is installed between adjacent sound-absorbing boards 1. Installation components 2 are symmetrically arranged inside both ends of the sound-absorbing board 1. The first connecting component 4 includes a connecting post 43. The sound-absorbing plate 1 has symmetrically arranged insertion holes 41 and second threaded holes 42 on the inner side walls at both ends. A threaded post 44 is fixedly installed on the left end of the connecting post 43. The threaded post 44 is threadedly connected to the inside of the second threaded hole 42. The right end of the connecting post 43 is slidably connected to the inside of the insertion hole 41, and the side walls of adjacent sound-absorbing plates 1 are in contact with each other. After connecting the threaded post 44 to the inside of the second threaded hole 42, the insertion holes 41 of adjacent sound-absorbing plates 1 are slidably sleeved on the right end of the connecting post 43 until the side walls of adjacent sound-absorbing plates 1 are in contact with each other.

[0016] The second connecting component 5 includes a T-shaped plate 52. The rear side wall of the sound-absorbing plate 1 is provided with a T-shaped groove 51. The T-shaped plates 52 are slidably connected to the inside of the T-shaped groove 51, and the length of each T-shaped plate 52 is less than the length of the T-shaped groove 51. Both ends of the T-shaped groove 51 are open. When adjacent sound-absorbing plates 1 are connected, the adjacent sound-absorbing plates 1 are slidably sleeved onto the T-shaped plate 52 through the rear T-shaped groove 51, thereby strengthening the stability of the connection between adjacent sound-absorbing plates 1.

[0017] The second connecting component 5 also includes a connecting rod 54. Connecting holes 53 are provided inside the side walls at both ends of the T-shaped plate 52, and the interiors of the connecting holes 53 on both sides are interconnected. The two ends of the connecting rod 54 are slidably connected to the interiors of the connecting holes 53 on one side of the adjacent sound-absorbing plate 1. The diameter of the connecting rod 54 matches the diameter of the connecting holes 53, and the side walls of the connecting rod 54 are tightly fitted to the side walls of the connecting holes 53, with friction present. A limiting piece 55 is fixedly sleeved on the outside of the connecting rod 54, and its diameter is smaller than the width of the T-shaped plate 52. This allows the T-shaped plate 52 to be installed according to the connection and number of adjacent sound-absorbing plates 1, making the connection of the sound-absorbing plates 1 more convenient. The limiting piece 55 prevents the connecting rod 54 from completely entering the interior of the connecting hole 53.

[0018] The mounting assembly 2 includes bolts 21. The sound-absorbing panel 1 has symmetrical mounting grooves 23 at both ends, and each mounting groove 23 has a first threaded hole 22. Bolts 21 are threaded into each of the first threaded holes 22, and the diameter of the bolt 21's nut matches the inner diameter of the mounting groove 23. The diameter of the first threaded hole 22 is smaller than the diameter of the mounting groove 23. After the sound-absorbing panel 1 is installed, it is mounted on the wall. Then, the bolts 21 are threaded into the first threaded holes 22 and connected to the interior of the wall through the internal threads of the first threaded holes 22.

[0019] Each of the mounting grooves 23 is sealed with a sealing plug 3. The top sidewall of the sealing plug 3 is horizontal to the top sidewall of the sound-absorbing plate 1, and the bottom of each sealing plug 3 is attached to the top sidewall of the bolt 21. After the bolt 21 is installed, the sealing plug 3 is connected to the inside of the mounting groove 23, which can limit the bolt 21 and prevent it from loosening.

[0020] The first connecting component 4 also includes a sealing ring 45, which is fixedly sleeved at equal intervals on the right end of the connecting post 43 and respectively sealed inside the socket 41; when the connecting post 43 enters the socket 41, the sealing ring 45 can make the connection between the connecting post 43 and the socket 41 tight and secure.

[0021] The rear sidewalls of the T-shaped plate 52 connected inside the T-shaped groove 51 are all horizontal with the rear sidewalls of the sound-absorbing plate 1. It should be noted that the T-shaped plate 52 can strengthen and stabilize the connection between adjacent sound-absorbing plates 1.

[0022] The working principle of this utility model is as follows: When installing the sound-absorbing panel 1, the sound-absorbing panel 1 is first fixed to the wall or other supporting surface using the mounting assembly 2. At the same time, adjacent sound-absorbing panels 1 are snapped onto the T-shaped plate 52, and the T-shaped plate 52 is slidably connected to the inside of the T-shaped groove 51. The bolt 21 is threaded into the first threaded hole 22 to complete the initial positioning. Subsequently, the first connecting assembly 4 is used to securely connect adjacent sound-absorbing panels 1, and the threaded post 44 is threaded into the inside of the second threaded hole 42. Then, the insertion hole 41 on the adjacent sound-absorbing panel 1 is slidably fitted onto the connecting post 43. During this process, the sealing ring 45 can effectively prevent external dust. Dust or moisture can enter the connection points, thereby improving the overall structural durability. For scenarios requiring further reinforcement, additional support can be provided through the second connection component 5. The T-shaped plate 52 is embedded in the T-shaped groove 51 and fixed by the connecting rod 54 passing through the connection hole 53. The limiting piece 55 serves to limit the position, ensuring a more secure connection. When disassembly or cutting is required, the connecting column and T-shaped plate can be easily removed without affecting the subsequent use of the sound-absorbing panel. In addition, if the sound-absorbing panel 1 needs to be cut and adjusted, its detachable design allows for easy replacement or reassembly of related components, greatly improving operational flexibility and material utilization.

[0023] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
