Description
Technical Field
[0001] This invention relates to the field of indoor cardboard technology, specifically to an indoor cardboard with sound insulation function. Background Technology
[0002] Sound-insulating indoor cardboard is an innovative building material that combines sound absorption and sound insulation properties to improve the acoustics of the indoor environment. This type of cardboard, also known as sound-absorbing or sound-insulating cardboard, is a type of construction cardboard. Its unique feature lies in its porous structure and soft texture, which gives it excellent sound absorption properties. Simultaneously, due to the special nature of its materials and manufacturing process, this cardboard also possesses certain thermal insulation properties. In its manufacturing process, this cardboard uses renewable resources such as wood, rice and wheat straw, bagasse, and corn stalks as raw materials, and is produced through processes including pulping, papermaking, and drying.
[0003] The prior art discloses a sound-insulating paper-faced gypsum board (publication number CN212376180U), comprising a sound-insulating gypsum board and a paper protective board covering the surface of the sound-insulating gypsum board. A vacuum board is wrapped inside the sound-insulating gypsum board. The vacuum board includes a sealing layer and a gypsum layer. The interior of the vacuum board is a vacuum environment. The gypsum layer consists of two layers of gypsum board connected at the middle by a gypsum support frame. The gypsum layer is wrapped within the sealing layer, and fixing blocks are spaced apart on both the top and bottom surfaces of the sealing layer. By utilizing the vacuum environment within the vacuum board, an absolute sound-insulating layer is formed within the gypsum board layers, effectively improving the sound insulation effect of the sound-insulating paper-faced gypsum board and compensating for the poor sound absorption effect when paper-faced gypsum board is used as an indoor soundproof wall.
[0004] Existing soundproof indoor cardboard utilizes the vacuum environment within the vacuum board to form an absolute soundproof layer within the gypsum board layer, effectively improving the soundproofing effect of the gypsum board. However, simply adding a soundproof layer to the aforementioned indoor cardboard results in only average soundproofing performance, and there are no components that can be connected and adhered to each other, making it impossible to stack them to enhance the soundproofing effect. This makes it impractical. Therefore, it is necessary to design a more practical indoor cardboard. Summary of the Invention
[0005] The purpose of this invention is to provide an indoor cardboard with sound insulation function to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an indoor cardboard with sound insulation function, comprising a lightweight fiberboard, a sound insulation material layer, a bottom lightweight fiberboard layer and a flat lightweight fiberboard layer, wherein the surface of the lightweight fiberboard is provided with a folding structure, the surface of the lightweight fiberboard is provided with a butt joint structure, and the side of the lightweight fiberboard is provided with a side end connection structure.
[0007] The folding structure includes an elastic triangular block, a folding groove, an inner connecting elastic band, an arc-shaped pad, a connecting spring, and a second connecting band.

[0029] Please see Figure 1-6 The present invention provides the following technical solutions:
[0030] An indoor cardboard with sound insulation function includes a lightweight fiberboard 1, a sound insulation material layer 2, a bottom lightweight fiberboard layer 3, and a flat lightweight fiberboard layer 4. The surface of the lightweight fiberboard 1 is provided with a folding structure 5, the surface of the lightweight fiberboard 1 is provided with a butt joint structure 6, and the side of the lightweight fiberboard 1 is provided with a side end connection structure 7.
[0031] The folding structure 5 includes an elastic triangular block 501, a folding groove 502, an inner connecting elastic band 503, an arc-shaped pad 504, a connecting spring 505, and a second connecting band 506. The elastic triangular block 501 is fixedly connected to the top center of the lightweight fiberboard 1. A triangular mating groove is provided at the bottom of the lightweight fiberboard 1. The inner connecting elastic band 503 is fixedly connected to the inside of the lightweight fiberboard 1. The arc-shaped pad 504 is fixedly connected to the side of the inner connecting elastic band 503. The second connecting band 506 is fixedly connected to the inside of the lightweight fiberboard 1. The connecting spring 505 is fixedly connected to the inside of the lightweight fiberboard 1. One end of the inner connecting elastic band 503 away from the inside of the lightweight fiberboard 1 is fixedly connected to the side of the arc-shaped pad 504. On the surface, the elastic triangular block 501 has a groove inside, and the folding groove 502 is opened on the top of the lightweight fiberboard 1. The spacing of the folding groove 502 is adapted to the width of the groove. The end of the second connecting strip 506 away from the interior of the lightweight fiberboard 1 is fixedly connected to the side of the arc-shaped pad 504. The end of the connecting spring 505 away from the interior of the lightweight fiberboard 1 is fixedly connected to the side of the arc-shaped pad 504. The elastic triangular block 501 can be inserted into the bottom of the lightweight fiberboard 1 and then contact the arc-shaped pad 504. The elastic force of the connecting spring 505 is used to squeeze in the opposite direction to help connect. This can further increase the strength of the lightweight fiberboard 1, the sound insulation material layer 2, and the bottom lightweight fiberboard layer 3 stacked on top of each other.
[0032] The docking structure 6 includes a docking slot 601, a docking post 602, a through hole 603, and a docking ring 604. The docking slot 601 is located at the top of the lightweight fiberboard 1. The docking post 602 is fixedly connected to the bottom of the lightweight fiberboard 1. The through hole 603 is located at the bottom of the lightweight fiberboard 1. The docking ring 604 is fixedly connected to the top of the lightweight fiberboard 1. The volume of the docking post 602 is adapted to the volume of the docking slot 601. The docking post 602 is inserted into the interior of the docking slot 601. During docking, the docking post 602 can be inserted into the docking slot 601. At the same time, the docking ring 604 can also be inserted into the through hole 603 to connect vertically, helping the lightweight fiberboard 1, the sound insulation material layer 2, and the bottom lightweight fiberboard layer 3 to be stacked vertically. The diameter of the docking ring 604 is adapted to the inner diameter of the through hole 603. The docking ring 604 is inserted into the interior of the through hole 603.
[0033] The side connection structure 7 includes a hook and loop fastener surface 701 and a hook and loop barbed surface 702. The hook and loop fastener surface 701 is fixedly connected to the right side of the lightweight fiberboard 1, and the hook and loop barbed surface 702 is fixedly connected to the left side of the planar lightweight fiberboard layer 4. The side area of the hook and loop barbed surface 702 is equal to that of the hook and loop fastener surface 701, and the hook and loop barbed surface 702 is bonded to the hook and loop fastener surface 701.
[0034] In use, the cardboard mainly consists of three layers: an outer layer of lightweight fiberboard 1, a middle layer of sound insulation material 2, and an inner layer of lightweight fiberboard 3. These three layers are stacked together. During stacking, the folding structure 5 and the mating structure 6 work together to ensure connection strength. The sound insulation material layer effectively isolates noise transmission, improving the cardboard's sound insulation effect. The cardboard surface is designed with concave and convex structures, namely mating slots 601 and mating posts 602. During mating, the mating post 602 can be inserted into the mating slot 601, and the mating ring 604 can also be incorporated into the perforation 603. The perforation 603 and the mating ring 604 constitute a perforated structure. These perforated structures can introduce an air layer, forming an airborne sound insulation layer, thereby further improving the cardboard's sound insulation effect. Simultaneously, the perforated structure can also increase the cardboard's breathability and sound absorption performance, making the indoor environment more comfortable. These structures not only increase the cardboard's strength but also effectively reflect and scatter noise, further reducing noise transmission. The cardboard can be designed with a folding structure using the folding structure 5, allowing for folding as needed. When folding, pull the two sides of the lightweight fiberboard 1 as needed. Folding can be achieved by using the folding groove 502 and the groove inside the elastic triangular block 501. Folding and unfolding adjust the sound insulation performance and space utilization of the cardboard. This design not only facilitates transportation and storage but also allows for flexible adjustment of the cardboard's size and shape according to actual needs. The elastic triangular block 501, the curved pad 504, and the connecting spring 505 can also be connected vertically. In use, the lightweight fiberboard 1 is stacked on the sound insulation material layer 2. The elastic triangular block 501 at the top of the sound insulation material layer 2 can be inserted into the bottom of the lightweight fiberboard 1, then contact the curved pad 504, and the connecting spring 505 provides reverse compression to aid in connection. A side-end connection structure 7 is provided on the side of the lightweight fiberboard 1. In use, the sides of the lightweight fiberboard 1 and the flat lightweight fiberboard layer 4 can be adhered together, and then connected using the Velcro surface 701 and the Velcro barbed surface 702. This connection increases the contact area of the cardboard and improves its performance.
