[0027] Embodiment 1, as Figure 1As shown, a sound-absorbing panel for a soundproof room comprises two keels 1, two crossbeams 2 are fixedly connected to the two keels 1, sound-absorbing cotton 4 is arranged on the keels 1, and a sound-absorbing panel body 3 is arranged on the keels 1.

[0028] Reference Figure 1 and Figure 2 The keel 1 is provided with a mounting structure 5, which is mainly composed of a slide groove 51. The slide groove 51 is provided on the keel 1. Two sliders 52 are slidably connected in the slide groove 51. Two card slots 53 are provided on the sound-absorbing board body 3. The sound-absorbing cotton 4 cut to a suitable size is inserted into the space formed by the keel 1 and the crossbeam 2, and then the slider 52 is inserted into the corresponding card slot 53, and the sound-absorbing board body 3 is installed on the keel 1, so that the sound-absorbing board body 3 and the sound-absorbing cotton 4 are fitted together without adhesion, which is convenient for disassembly, thereby avoiding the current sound-absorbing cotton 4 being adhered to the sound-absorbing board. When the sound-absorbing cotton 4 needs to be replaced, it is difficult to disassemble it, and it usually needs to be replaced together with the sound-absorbing board, which causes waste. A limiting rod 54 is fixedly connected to the slider 52, and limiting grooves 55 are respectively provided on the inner walls on both sides of the card slot 53. The limiting rod 54 and the The size of the limiting grooves 55 is adapted, and the limiting rod 54 is inserted into the corresponding limiting groove 55, so that the connection between the sound-absorbing board body 3 and the keel 1 can be more stable. A bidirectional screw 56 is rotatably connected in the slide groove 51, and the bidirectional screw 56 is threadedly connected to the two sliders 52. The two sections of the thread on the bidirectional screw 56 are in opposite directions. Since the slider 52 slides in the slide groove 51, rotating the bidirectional screw 56 can drive the two sliders 52 to move closer to or away from each other, so that the position of the slider 52 is more stable. A first bevel gear 57 is fixedly connected to the bidirectional screw 56, and a second bevel gear 58 is meshedly connected to the first bevel gear 57. A knob 59 is rotatably connected to the keel 1, and the knob 59 is fixedly connected to the second bevel gear 58. Rotating the knob 59 can drive the second bevel gear 58 to rotate, and then drive the first bevel gear 57 to rotate, making the operation more convenient.

[0029] Reference Figure 3 and Figure 4The sound-absorbing board body 3 is provided with a connecting structure 6, which is mainly composed of a trapezoidal block 61. The trapezoidal block 61 is fixedly connected to the sound-absorbing board body 3. A trapezoidal groove 62 is provided on the sound-absorbing board body 3. The size of the trapezoidal block 61 and the trapezoidal groove 62 are adapted to each other. When connecting multiple sound-absorbing board bodies 3, the trapezoidal block 61 on one sound-absorbing board body 3 is inserted into the trapezoidal groove 62 on the adjacent sound-absorbing board body 3, so that the connection between the two sound-absorbing board bodies 3 can be more stable. A cavity 63 is provided in the trapezoidal block 61, and a plurality of piston rods 64 are slidably inserted on the trapezoidal block 61. Pulling the plurality of piston rods 64 upward will drive the inner wall of the cavity 63 to tighten inward, making it convenient for the trapezoidal block 61 to be inserted into the trapezoidal groove 62. After being inserted, the piston rod 64 will be pushed to slide inward, thereby inflating the trapezoidal block 61 and improving the trapezoidal block 61. In order to improve the stability of the connection with the trapezoidal groove 62, a first magnetic block 65 is fixedly connected to several piston rods 64, and a second magnetic block 66 is fixedly connected in the trapezoidal groove 62. The two surfaces in contact with the first magnetic block 65 and the second magnetic block 66 are of opposite poles. The trapezoidal block 61 is inserted into the trapezoidal groove 62, and the first magnetic block 65 and the second magnetic block 66 are attracted together, which can further improve the connection effect. Several telescopic rods 67 are fixedly connected in the cavity 63, and a spring 68 is sleeved on the telescopic rod 67. The two ends of the spring 68 are respectively fixedly connected to the inner walls on both sides of the cavity 63. When the inner wall of the cavity 63 is tightened, the telescopic rod 67 will be squeezed to contract, thereby causing the spring 68 to contract. Therefore, after the trapezoidal block 61 is inserted into the trapezoidal groove 62, the rebound elastic force of the spring 68 acts on the inner wall of the cavity 63, making it tightly against the inner wall of the trapezoidal groove 62.

[0030] Working principle: the sound-absorbing cotton 4 cut to a suitable size is inserted into the space formed by the keel 1 and the crossbeam 2, and then the slider 52 is inserted into the corresponding slot 53, and the sound-absorbing board body 3 is installed on the keel 1, so that the sound-absorbing board body 3 and the sound-absorbing cotton 4 are fitted together without adhesion, which is convenient for disassembly, thereby avoiding the current sound-absorbing cotton 4 adhering to the sound-absorbing board. When the sound-absorbing cotton 4 needs to be replaced, it is difficult to disassemble it, and usually it needs to be replaced together with the sound-absorbing board, which causes waste. The limit rod 54 is inserted into the corresponding limit slot 55, which can make the connection between the sound-absorbing board body 3 and the keel 1 more stable. Since the slider 52 slides in the slide slot 51, rotating the bidirectional screw 56 can drive the two sliders 52 to move closer to or away from each other, making the position of the slider 52 more stable. Turning the knob 59 can drive the second bevel gear 58 to rotate, and then drive the first bevel gear 57 to rotate, so that The operation is more convenient. When connecting multiple sound-absorbing board bodies 3, the trapezoidal block 61 on one sound-absorbing board body 3 is inserted into the trapezoidal groove 62 on the adjacent sound-absorbing board body 3, which can make the connection between the two sound-absorbing board bodies 3 more stable. Pulling a number of piston rods 64 upwards will drive the inner wall of the cavity 63 to tighten inward, making it convenient for the trapezoidal block 61 to be inserted into the trapezoidal groove 62. After being inserted, the piston rod 64 will be pushed to slide inward, thereby inflating the trapezoidal block 61, thereby improving the stability of the connection between the trapezoidal block 61 and the trapezoidal groove 62. When the trapezoidal block 61 is inserted into the trapezoidal groove 62, the first magnetic block 65 and the second magnetic block 66 are attracted together, which can further improve the connection effect. When the inner wall of the cavity 63 is tightened, the telescopic rod 67 will be squeezed to contract, thereby causing the spring 68 to contract. Therefore, after the trapezoidal block 61 is inserted into the trapezoidal groove 62, the rebound elastic force of the spring 68 acts on the inner wall of the cavity 63, making it tightly against the inner wall of the trapezoidal groove 62.
