DETAILED DESCRIPTION

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0038] Reference Figure 1 As shown, in the first aspect, a preferred embodiment of the utility model provides a suspended sound absorber assembly, comprising a sound absorber 1 and a profile 2; the profile 2 is arranged in parallel to form a plane skeleton, the sound absorber 1 is perpendicular to the plane skeleton, and the sound absorber 1 is connected to the lower part of the profile 2, and the sound absorber 1 and the profile 2 are clamped together; a first cavity 13 is formed inside the sound absorber 1, and a first opening 12 is provided at the upper end.

[0039] Specifically, refer to Figure 2 , Figure 3 As shown, in this embodiment, a single piece of polyester fiber sound-absorbing board is cut, and the cut sound-absorbing board is folded into a sound-absorbing body 1 of a required size. The length of the sound-absorbing body 1 is 1200 mm. The sound-absorbing body 1 is a rectangular hollow body as a whole, which solves the customer's requirement to increase the thickness of the single sound-absorbing board set at intervals in the sound-absorbing board ceiling; the application makes the single sound-absorbing board into a hollow body and opens an opening at the upper end of the hollow body to form the sound-absorbing body 1 connected to the outside, increases the sound insulation gap, can enhance the sound absorption effect, and more effectively absorb high-frequency noise. In terms of the amount of material used, under the same thickness requirement, making a hollow body also saves a lot of sound-absorbing materials.

[0040] The first opening 12 is formed at the upper end of the sound absorbing body 1, and the side panels 11 are arranged around the sound absorbing body 1. The bottom panel 14 is arranged at the lower end, and a first cavity 13 is formed between the side panels 11 and the bottom panel 14. In this embodiment, the side panels 11 and the bottom panel 14 are integrated and cut from the same polyester fiber sound absorbing board, so that the sound absorbing body 1 has a certain thickness, and the sound absorbing effect is increased, which not only simplifies the process but also saves sound absorbing materials.

[0041] The sound absorber 1 is arranged in parallel along a direction perpendicular to the length direction of the sound absorber 1. The upper ends of all the sound absorbers 1 form a plane. The profile 2 is arranged on the plane and is arranged perpendicular to the sound absorber 1. The material of the profile 2 is aluminum alloy, which has the advantages of light weight, precise size, and convenient production and processing. The length of the profile 2 is 1200mm. The upper end of the profile 2 is provided with multiple groups of gourd holes 24 distributed horizontally and equidistantly to accommodate more hanging points. During actual use and installation, the upper end of each group of profiles 2 can be fixed with a hanging wire through a nut 43 and connected to the roof, so as to install the suspended sound absorber assembly described in this application. In actual operation, the number of profiles 2 can be changed according to the length of the sound absorber 1 to ensure the stability of the overall structure.

[0042] Reference Figure 4 As shown, a second cavity 22 is formed inside the profile 2, and a second opening 23 is provided at the lower end. In this embodiment, two groups of profiles 2 are provided. The profile 2 is long and has an arched cross section. Hooks 21 extending upward into the second cavity 22 are provided on both sides of the second opening 23. The structure is designed in the form of an inner angle to ensure that the polyester fiber board has a sufficient bearing structure. A buckle 1111 is provided at the upper end of the first opening 12 of the sound absorber 1 to fit the hook 21. The buckle 1111 is provided at the bottom of the groove 111 and extends upward. The groove 111 is provided at the upper end of the side plate 11 and its position corresponds to the position of the hook 21. In this embodiment, the buckle 1111 is provided in two groups on the left and right, which are respectively engaged with the hook 21; the upper ends of the sound absorber 1 are fixed with the two groups of parallel profiles 2 by the buckles 1111.

[0043] By utilizing the rebound characteristics of the polyester fiberboard, a structure with a barb, namely, a buckle 1111, is processed on the board using numerical control equipment. The structure is an open type with one-way entry and exit. After being combined with the profile 2, the structure meets the design load-bearing capacity of not less than 2kg. The sound-absorbing body 1 can be inserted into the profile 2 in sequence after the profile 2 is installed, thereby solving the inconvenience of large-size hoisting. In addition, since the mounting hole on the sound-absorbing body 1 is not a closed-loop hole, when the sound-absorbing body 1 needs to be replaced, there is no need to disassemble the profile 2. The sound-absorbing body 1 can be removed by directly cutting off the connection point (buckle 1111) between the sound-absorbing body 1 and the profile 2, which makes replacement simple.

[0044] The present application processes and carves the polyester fiber sound-absorbing board through a carving process. Then the carved sound-absorbing board is folded into a sound-absorbing body 1 of a required size. When installing on site, it is only necessary to clip each sound-absorbing body 1 into the customized profile 2. Figure 6 As shown, after multiple sound absorbers 1 are inserted, a suspended sound absorber assembly is formed. Then multiple suspended sound absorber assemblies can be connected at will to form a large-area suspended ceiling. Under the same conditions of being beautiful and easy to install, the polyester fiber sound absorber 1 has a better sound absorption effect than a single board.

The connecting assembly includes: a first connecting member 41, a second connecting member and a nut 43; the first connecting member 41 is arranged on the outer surface of the keel 3 and wraps the keel 3, and screw holes 411 are arranged at both ends of the first connecting member 41; the second connecting member is arranged below the profile 2, and the second connecting member includes a connecting plate 421 and two studs 423 adapted to the screw holes 411, the studs 423 are arranged at the upper end of the connecting plate 421, and pass through the gourd hole 24; the nut 43 is arranged above the screw hole 411, and locks the stud 423, so that the profile 2 and the keel 3 are fixedly connected. In this embodiment, the keel 3 has the same size as the profile 2 and is also strip-shaped. Two groups of keels 3 are arranged in parallel, both of which are arranged perpendicular to the profile 2. A "well" shape is formed between the two groups of keels 3 and the two groups of profiles 2. The arrangement of the keel 3 makes the suspended sound-absorbing body assembly more secure and will not deform at will. In actual installation, the keel 3 can be fixed with a hanging wire and connected to the roof by using a fixing nut for installation.
