Technical Field

[0001] The utility model relates to the technical field of sound insulation materials, and more specifically to a sound absorbing board connector and a sound absorbing combined board. Background Art

[0002] Sound-absorbing board is an ideal sound-absorbing decorative material. It has the advantages of sound absorption, environmental protection, flame retardant, heat insulation, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, parquet, simple construction, good stability, good impact resistance, good independence, high cost performance, etc. There are a variety of colors to choose from, which can meet the needs of sound-absorbing decoration of different styles and levels.

[0003] The Chinese invention patent publication number is CN112112300A. On December 22, 2020, a new type of metal Slott sound-absorbing panel was disclosed. Furthermore, the connecting part is composed of splicing ribs and splicing slots. The splicing ribs and the splicing slots are respectively located at the two ends of the substrate. The adjacent substrates are fixedly connected by inserting the surface of the splicing ribs into the inner wall of the splicing slots.

[0004] Although the above invention patent provides a sound-absorbing board with good sound wave absorption effect, the two sound-absorbing boards are connected by splicing dowels and plug-in slots at the base plate. The above scheme still has shortcomings. In the above invention patent, the two sound-absorbing boards are fixed at the base plate of the sound-absorbing board, and the connection is not stable. In serious cases, when the connection of the sound-absorbing board is impacted by sound waves, the connection rotates slightly, collides, and produces abnormal noise. Utility Model Content

[0035] The sound-absorbing plate 200 is a material that can absorb sound waves and block the transmission of sound. The sound-absorbing plate 200 includes a substrate 220, which is a complete rectangular or square plane plate. A plurality of parallel support frames 230 are fixed in parallel on the substrate 220, and a vibrating fin 110 is fixed on the top of each support frame 230. The substrate 220, the adjacent support frames 230, and the adjacent vibrating fins 110 form a muffler cavity. The substrate 220 has a sound inlet hole connected to the muffler cavity. After the sound wave enters the muffler cavity through the sound inlet hole, it is reflected in the muffler cavity, and the sound wave energy is absorbed by the vibrating fin 110 and converted into the vibration kinetic energy of the vibrating fin 110.

[0036] Example 1

[0037] The utility model provides a sound absorbing plate 200 connecting piece, including a first fastener 100, the first fastener 100 has a vibrating fin 110, the vibrating fin 110 is a long thin plate, the first fastener 100 can be a wooden product or a metal product, specifically consistent with the material of the sound absorbing plate 200. A clamp 120, the clamp 120 is fixed to the bottom of the vibrating fin 110, and includes a first clamp 121 and a second clamp 122 arranged oppositely, the first clamp 121 and the second clamp 122 are thin plates with the same length as the vibrating fin 110. A clamping section 123 is provided between the first clamp 121 and the second clamp 122, the clamping section 123 is used to accommodate and fix the connecting portion 210 of the two sound absorbing plates 200 to be spliced, the connecting portion 210 is a long thin plate vertically fixed to the edge side of the substrate 220 of the sound absorbing plate 200. The connecting portion 210 is tightly matched with the inner wall of the clamping section 123 and causes the first clamping member 121 and the second clamping member 122 to produce local elastic deformation when connecting the connecting portion 210, thereby forming an elastic clamping force connecting the two sound absorbing panels 200. When the connecting portion 210 squeezes the inner walls of the first clamping member 121 and the second clamping member 122, it will inevitably cause the first clamping member 121 and the second clamping member 122 to produce a slight local deformation, and the greater the deformation, the stronger the clamping force generated. The first fastener 100 connects the sound absorbing panels 200 to be spliced ​​in a direction perpendicular to the sound absorbing panels 200, such as the clamping section 123 formed by the first clamp 120 and the second clamp 120 is inserted into the connecting portion 210 in a direction perpendicular to the sound absorbing panels 200, so as to apply a clamping force from both sides of the connecting portion 210, making the connection more stable.

[0038] In the present application, the first fastener 100 can connect the sound absorbing panels 200 to be spliced ​​in a direction perpendicular to the sound absorbing panels 200, and the clamping section 123 formed by the gap between the first clamping member 121 and the second clamping member 122 is tightly matched with the connecting portion of the two sound absorbing panels 200, and the clamping force provided by the local elastic deformation of the first clamping member 121 and the second clamping member 122 is used to make the connection between the two sound absorbing panels 200 tighter and more stable, avoiding problems such as easy falling off and abnormal noise.

[0039] The first clamping member 121 and the second clamping member 122 are both long flat plates, which are parallel and fixed at intervals on the bottom of the vibrating fin 110. The first clamping member 121 and the second clamping member 122 are fixed to the vibrating fin 110 to hide the first clamping member 121 and the second clamping member 122, without affecting the appearance and use of the sound absorbing plate 200.

[0040] Example 2

[0041] The first clamping member 121 and the second clamping member 122 are both fixed with convex strips 124 on the side away from the vibrating fin 110. The two convex strips 124 are located in the clamping section 123 and are arranged opposite to each other. The convex strips 124 can reduce the contact area with the connecting portion 210, reduce the friction during installation, and facilitate installation. The bottom of the convex strips 124 has a rounded corner or a beveled corner. The rounded corner or chamfered bottom of the convex strips 124 can play a guiding role, making it easier for the splicing plate connecting portion 210 to be inserted into the clamping section 123.

[0042] Example 3

[0043] In this embodiment, the number of the clamps 120 is two or more, and the multiple clamps 120 are arranged in a straight line and fixed at the bottom of the vibrating fin 110. The first clamp 121 and the second clamp 122 of each clamp 120 are relatively short, opposite and spaced to form clamping intervals 123 respectively. Generally, a clamp 120 is fixed at the bottom of each end of the vibrating fin 110, and the connecting parts 210 at both ends of the sound absorbing plate 200 to be spliced ​​are clamped thereto, and the length of the first clamp 121 and the second clamp 122 is selected to be smaller than the vibrating fin 110. Compared with using one clamp 120 to fix the entire connecting part 210, it can save consumables and reduce the weight of the connecting parts of the sound absorbing plate 200. If you want to improve the stability of the clamp 120, you only need to increase the number of clamps 120.

[0044] Example 4

[0045] In this embodiment, the sound absorbing panel 200 connecting member includes a second fastener 300, and the second fastener 300 includes a protrusion 310 extending from the edge of one sound absorbing panel 200 and a groove 320 provided at a corresponding position of the edge of another sound absorbing panel 200, the protrusion 310 is engaged in the groove 320 to achieve connection and fixation, and the second fastener 300 is detachably fixedly connected to the sound absorbing panels 200 to be spliced ​​in a direction parallel to the sound absorbing panels 200. The second fastener 300 is detachably fixedly connected to the sound absorbing panels 200 to be spliced ​​in a direction parallel to the sound absorbing panels 200, and cooperates with the first fastener 100, so that the spliced ​​panels can be more tightly connected in the horizontal and vertical directions of the sound absorbing panels, so that the spliced ​​panels are more tightly connected.
