Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing panels, in particular to a decorative flame-retardant sound-absorbing panel. Background Art

[0002] Sound-absorbing panels refer to plate-shaped materials that have sound-absorbing and noise-reducing properties. They are mainly used in theaters, concert halls, libraries, interrogation rooms, multi-purpose halls, hospitals, shopping malls, schools, conference rooms, studios, recording studios and other places that have high requirements for acoustic environment and high-end decoration.

[0003] When installing the existing sound-absorbing panels, the keel is first installed on the wall, and then the sound-absorbing panels are installed on the keel, and then the sound-absorbing cotton is filled between the wall and the sound-absorbing panels. This makes it difficult to fill the sound-absorbing cotton to the bottom of the wall to contact the sound-absorbing panels, which results in no sound-absorbing cotton between the sound-absorbing panels and the wall below. The unevenly installed sound-absorbing cotton will greatly reduce the sound absorption effect, affecting the sound absorption effect of the sound-absorbing panels;

[0004] Another method is to install the sound-absorbing cotton first and then install the sound-absorbing board. This means that when installing the sound-absorbing cotton, the workers need to press the sound-absorbing cotton with their hands to support it to prevent it from falling over. This requires multiple people to cooperate in the construction, which wastes manpower and is not convenient for installation, significantly reducing the installation efficiency of the sound-absorbing cotton and the sound-absorbing board. Therefore, a decorative flame-retardant sound-absorbing board is proposed to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-9 A decorative flame-retardant sound-absorbing board, comprising a grooved wood sound-absorbing board body 1 and a keel 5, a steel plate 3 is arranged on one side of the grooved wood sound-absorbing board body 1, two steel plates 3 are arranged and are symmetrical to each other, the grooved wood sound-absorbing board body 1 and one of the steel plates 3 are connected by a connecting assembly, the connecting assembly comprises a connecting groove opened at one end of the grooved wood sound-absorbing board body 1, a plurality of connecting plates 101 are fixedly connected in the connecting groove, a plurality of connecting ports are opened at one end of the connecting plate 101, a plurality of trapezoidal grooves are opened at one end of the steel plate 3, a plurality of inclined plates 6 are fixedly connected below the trapezoidal groove, a plurality of trapezoidal mounting grooves are opened in the inclined plate 6, a moving block 9 is slidably connected in the trapezoidal mounting groove, a trapezoidal clamping block 901 clamped with the connecting port is fixedly connected to the bottom end of the moving block 9, (the trapezoidal clamping block 901 is squeezed and pushed upward by the connecting plate 101, and then moved downward by its own gravity and clamped into the connecting plate 101, so as to realize the installation of the grooved wood sound-absorbing board body 1 and one of the steel plates 3);

[0028] Sound-absorbing cotton 4 is installed between the symmetrical steel plates 3 through a docking assembly (the sound-absorbing cotton 4 absorbs sound). The docking assembly includes two pairs of symmetrical trapezoidal plug-in blocks 301 fixedly connected to one end of one of the steel plates 3. A pair of symmetrical notches are provided at the top of the trapezoidal plug-in block 301. Two pairs of symmetrical through holes are provided on the surface of the sound-absorbing cotton 4. One end of the other steel plate 3 is fixedly connected to a hollow square tube 302 that fits the trapezoidal plug-in block 301. A trapezoidal moving groove is provided at the top of the inner part of the hollow square tube 302. A sliding block 10 is slidably connected in the trapezoidal moving groove. A trapezoidal plug plate 1001 plugged into the notch is fixedly connected to the bottom end of the sliding block 10 (the trapezoidal plug block 301 is passed through the sound-absorbing plate and inserted into the hollow square tube 302, so that the trapezoidal plug plate 1001 moves up and moves down by its own gravity, and is stuck in the trapezoidal plug block 301, thereby realizing the connection between the two steel plates 3 and the fixation of the sound-absorbing cotton 4).

[0029] Furthermore, another steel plate 3 is connected to the keel 5 through an installation component, and the installation component includes a installation block 7 fixedly connected to one end of the other steel plate 3. Two keels 5 are provided and are symmetrical to each other. One end of the keel 5 is provided with a plurality of circular holes (the circular holes are convenient for fixing the keel 5 to the wall using expansion screws), and the two inner side surfaces of the keel 5 are provided with a plurality of limiting holes. Symmetrical receiving grooves are provided at both ends of the installation block 7, and springs 701 are provided in the symmetrical receiving grooves. One end of the spring 701 is fixedly connected to a slider 801 slidably connected to the receiving groove, and one end of the slider 801 is fixedly connected to a trapezoidal block 8 engaged with the limiting hole (through the cooperation of the spring 701 and the trapezoidal block 8, the trapezoidal block 8 is engaged in the limiting hole to realize the installation of the overall device and the keel 5).

[0030] It should be noted that: a flow groove is opened at one end of the connecting plate 101, the bottom end of the grooved wood sound-absorbing board body 1 is fixedly connected with a hollow storage box 2 (the hollow storage box 2 collects the liquid after the sound-absorbing cotton 4 is melted), the inner bottom end of the grooved wood sound-absorbing board body 1 and the top of the hollow storage box 2 are opened with a guide groove, and one end of the grooved wood sound-absorbing board body 1 is fixedly connected with a guide plate 102 extending to the inside of the hollow storage box 2 through the guide groove.

[0031] A further advantage of adopting the above method is that the above device first installs the sound-absorbing cotton 4 and the sound-absorbing board, and then installs it on the keel 5, thereby avoiding the situation where there is no sound-absorbing cotton 4 between the sound-absorbing board below and the wall. The unevenly installed sound-absorbing cotton 4 will greatly reduce the sound absorption effect and affect the sound absorption effect of the sound-absorbing board; at the same time, the method of first installing the sound-absorbing cotton 4 and the sound-absorbing board does not require staff to support the sound-absorbing cotton 4, and does not require multiple people to cooperate in the construction, which avoids waste of manpower and facilitates its installation, significantly improving the installation efficiency of the sound-absorbing cotton 4 and the sound-absorbing board; at the same time, the liquid after the sound-absorbing cotton 4 is melted is collected to prevent the liquid from flowing out of the sound-absorbing board, thereby playing a combustion-promoting effect.

[0032] When the utility model is used: when it is necessary to install the sound-absorbing cotton 4 and the sound-absorbing board on the wall, the staff first places the keel 5 at a suitable position on the wall surface, and then uses the expansion screws to fix the keel 5 on the wall, and then the staff docks the grooved wood sound-absorbing board body 1 with one of the steel plates 3, so that the connecting plate 101 squeezes the trapezoidal clamping block 901 and pushes the trapezoidal clamping block 901 to move upward. When one end of the grooved wood sound-absorbing board body 1 contacts the steel plate 3, the trapezoidal clamping block 901 moves downward by its own gravity and is clamped into the connecting plate 101, so that the grooved wood sound-absorbing board body 1 and one of the steel plates 3 are installed;

[0033] Then the staff docks the sound-absorbing cotton 4 with one of the steel plates 3, and plugs the trapezoidal plug-in block 301 with the sound-absorbing cotton 4, and then docks the other steel plate 3 with the sound-absorbing cotton 4, plugs the hollow square tube 302 with the sound-absorbing cotton 4, and plugs the trapezoidal plug-in block 301 with the hollow square tube 302. When the trapezoidal plug-in block 301 is plugged with the hollow square tube 302, the trapezoidal plug-in block 301 will push the trapezoidal plug-in plate 1001 to move upward. When the two steel plates 3 sandwich the sound-absorbing cotton 4 in the middle, the trapezoidal plug-in block moves downward due to its own gravity and is stuck in the trapezoidal plug-in block 301, thereby realizing the connection of the two steel plates 3 and the fixation of the sound-absorbing cotton 4.

[0034] When the mounting block 7 is inserted into the keel 5, the trapezoidal clamping block 8 is squeezed by the keel 5 and shrinks into the mounting block 7. When the mounting block 7 contacts the inner wall of the keel 5, the spring 701 drives the trapezoidal clamping block 8 to reset, so that the trapezoidal clamping block 8 is clamped with the keel 5, thereby realizing the installation of the grooved wood sound-absorbing board and the sound-absorbing cotton 4 and the keel 5. The above device first installs the sound-absorbing cotton 4 with the sound-absorbing board, and then installs it on the keel 5. There is no sound-absorbing cotton 4 between the sound-absorbing board and the wall below. The unevenly installed sound-absorbing cotton 4 will greatly reduce the sound absorption effect and affect the sound absorption effect of the sound-absorbing board; at the same time, the method of first installing the sound-absorbing cotton 4 with the sound-absorbing board does not require the staff to support the sound-absorbing cotton 4, does not require multiple people to cooperate in the construction, avoids waste of manpower, facilitates its installation, and significantly improves the installation efficiency of the sound-absorbing cotton 4 and the sound-absorbing board.

[0035] When a fire occurs, due to the characteristics of the grooved wood sound-absorbing board body 1 (grooved on the front and perforated on the back), the high temperature generated by the fire will melt the sound-absorbing cotton 4. When the sound-absorbing cotton 4 melts and produces liquid, the liquid will flow to the guide plate 102 through the inclined shape formed by the inclined plate 6 and the connecting plate 101, and fall into the hollow storage box 2 through the guide plate 102, thereby preventing the liquid from flowing out and contacting the fire, thereby avoiding the effect of promoting combustion.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
