DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model will be further described in conjunction with the accompanying drawings, but the present utility model is not limited to these embodiments.

[0019] AsFigure 1-6 As shown in the figure, the utility model provides a assembled sound insulation device, which includes a sound insulation board frame 1 with a rectangular structure having an open end and a cover plate 2 arranged at the opening end of the sound insulation board frame 1. A plurality of sound insulation boards 3 are arranged in the sound insulation board frame 1. Both ends of the bottom of the cover plate 2 are connected to the sound insulation board frame 1 through connectors 4. The connector 4 includes a plug rod 401, a pull rod 402 and a return spring 403. A slot 404 adapted to the plug rod 401 is opened at the top of the sound insulation board frame 1. The plug rod 401 is fixedly connected to the bottom of the cover plate 2, and a limiting hole 405 is opened on the plug rod 401. Slide holes 406 and fixing holes 407 are respectively opened on both sides of the slot 404 on the sound insulation board frame 1. The slide hole 406 and the fixing hole 407 are coaxially arranged. The return spring 403 is arranged in the slide hole 406. One end of the return spring 403 away from the slide hole 406 is fixedly connected to the slide hole 406. One end of the pull rod 402 passes through the return spring 403 and is fixedly connected with a first connection block 408.

[0020] As Figure 1-4 shown, in this embodiment, the outer diameter of the first connection block 408 is between the inner diameter of the return spring 403 and the inner diameter of the slide hole 406, so that the first connection block 408 can slide in the slide hole 406 and can prevent the pull rod 402 from disengaging from the return spring 403. The sound insulation boards 3 are uniformly arranged one by one in the sound insulation board frame 1 and fixed by the cover plate 2. During the fixing process, the pull rod 401 is pulled outwards, the first connection block 408 is pulled into the slide hole 405, and the plug rod 401 at the bottom of the cover plate 2 is inserted into the slot 404. At this time, the axes of the limiting hole 405, the slide hole 406 and the fixing hole 407 on the plug rod 401 are on the same straight line. Then the pull rod 402 is released. Under the elastic action of the return spring 403, the first connection block 408 will sequentially enter the fixing hole 407 along the slide hole 406 and the limiting hole 405 to fix the plug rod 401. Screws and other installation tools are not used during the installation process, and the assembly is relatively simple, greatly shortening the installation time. And conversely, when cleaning or maintaining the sound insulation board 3, it can be quickly disassembled, thus avoiding damage to the whole.

[0021] The sound insulation board 3 sequentially includes a steel plate 301, a damping felt 302, a rock wool 303, a glass wool 304 and an aluminum perforated plate 305 from the inside.

[0022] As Figure 6As shown, in this embodiment, the thickness of the steel plate 301 is 1 mm, the thickness of the damping felt 302 is 4 mm, the thickness of the rock wool 303 is 100 mm, the thickness of the glass wool 304 is 50 mm, and the thickness of the aluminum perforated plate 305 is 1 m. By using the rigidity of the steel plate 301 and the sound permeability of the aluminum perforated plate 305, the good rigidity and sound permeability of the sound insulation panel body 3 are ensured. The damping felt 302 mainly increases the sound insulation amount of solids. It can effectively reduce the transmission of sound through the fixed structure and improve the sound insulation effect by absorbing vibration energy. The rock wool 303 has good sound absorption performance, which helps to absorb sound waves, thereby improving the overall sound insulation effect of the sound insulation panel body 3. The fiber structure of the glass wool 304 can help to absorb and scatter sound waves and reduce the transmission of sound. The noise is attenuated layer by layer through multiple layers of materials to achieve a better noise reduction effect.

[0023] Grooves 101 for accommodating the sound insulation panel body 3 are provided on the bottom inner wall of the sound insulation panel frame 1 and the bottom of the cover plate 2, and rubber gaskets are provided in the grooves 101.

[0024] As Figure 1 shown, the grooves 101 are used to prevent the sound insulation panel body 3 from shifting. The rubber gaskets at the lower part of the sound insulation panel body 3 can form an elastic isolation layer, which can cut off the fixed sound transmission effect and improve the sound insulation effect. The rubber gaskets are in close contact with the grooves 101 and the sound insulation panel body 3 to prevent sound from spreading through the gaps and ensure the maximization of the sound insulation effect.

[0025] A trapezoidal groove 306 is provided on one end face of the sound insulation panel body 3, and a trapezoidal protrusion 307 adapted to the trapezoidal groove 306 is provided on the other end face of the sound insulation panel body 3. First sliding grooves 102 and second sliding grooves 103 are respectively provided on the inner walls on both sides of the sound insulation panel frame 1. The first sliding groove 408 is adapted to the end of the sound insulation panel body 3 with the trapezoidal groove 306, and the second sliding groove 103 is adapted to the end of the sound insulation panel body 3 with the trapezoidal protrusion 307.

[0026] As Figure 1-4 shown, two adjacent sound insulation panel bodies 3 are clamped together through the trapezoidal groove 306 and the trapezoidal protrusion 307. On the one hand, it is convenient for installation, and on the other hand, it can better seal the splicing gap between two adjacent sound insulation panel bodies 3. Similarly, the first sliding groove 102 and the second sliding groove 103 are respectively adapted to the two ends of the sound insulation panel body 3 to prevent sound from spreading through the gaps and improve the sound insulation effect.

[0027] A second connecting block 409 is provided in the fixing hole 407. The first connecting block 408 and the second connecting block 409 both have magnetism and opposite magnetic polarities.

[0028] As Figure 1As shown, the first connecting block 408 and the second connecting block 409 are tightly adsorbed together, which can prevent the first connecting block 408 from detaching from the fixing hole 407 when the pull rod 401 is accidentally touched.

[0029] The other end of the pull rod 402 passes through the sliding hole 406 and is connected with a handle 410.

[0030] As Figure 2 shown, the handle 410 provides a force application point for the pull rod 402, which is convenient for pulling the pull rod 402 outwards.

[0031] Principle of use: First, assemble the sound insulation board bodies 3 one by one in the sound insulation board frame 1, then place the cover plate 2 on the top of the sound insulation board frame 1, pull the handle 410 outwards, pull the first connecting block 408 into the sliding hole 405, and insert the insertion rods 401 at the bottom of the cover plate 2 into the slots 404 respectively. Then release the pull rod 402. Under the elastic action of the return spring 403, the first connecting block 408 will sequentially enter the fixing hole 407 through the sliding hole 406 and the limiting hole 405 and be adsorbed together with the second connecting block 409 to fix the insertion rod 401. Screws and installation tools are not used during the installation process, and the assembly is relatively simple, greatly shortening the installation time. And conversely, when cleaning or maintaining the sound insulation board body 3, pull the handle 410 to make the first connecting block 408 away from the second connecting block 409, and sequentially enter the sliding hole 405 through the fixing hole 407 and the limiting hole 406, and quickly disassemble it without using tools, thus avoiding damage to the whole.
