Description

Technical Field

[0001] This application relates to the technical field of sound-insulating aluminum panels, and in particular to a sound-insulating aluminum panel. Background Technology

[0002] Soundproofing panels are panels designed to reduce noise. They are categorized into building soundproofing and structural soundproofing. Soundproofing panels do not block all frequencies of sound; objects have inherent resonant frequencies, and the soundproofing effect of the panel is significantly reduced when the sound is close to the object's resonant frequency.

[0003] A search revealed Chinese Patent Publication No. CN 215484047 U, which discloses a sound-insulating aluminum plate, comprising an aluminum plate body and a decorative plate. The decorative plate has a vertical groove in its center, and a connecting groove is formed on the aluminum plate body corresponding to the groove. A piston is slidably installed inside the groove, with its bottom surface fixedly connected to the top of a movable rod. The bottom end of the movable rod extends into the connecting groove on the aluminum plate body. The bottom ends of the movable rod are rotatably connected to one end of a connecting rod on each side, and the other ends of the connecting rods are rotatably connected to a slider. The sliders are slidably installed on the bottom surface of the decorative plate, and a locking pin is fixed to the side of the slider facing the inner wall of the connecting groove. Locking slots are formed on both sides of the connecting groove at positions corresponding to the locking pins. This invention eliminates the need to disassemble and reinstall the entire aluminum plate if the decorative pattern is incorrectly installed, facilitating timely correction of the decorative pattern, simplifying operation, and reducing the workload for workers.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the soundproof aluminum panels used cannot adjust their soundproofing effect according to the environmental requirements, resulting in a reduction in the soundproofing effect of the panels. Furthermore, the large internal space leads to reduced strength, shortens the service life of the soundproof panels, and reduces their ability to adapt to the environment. Utility Model Content

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a sound-insulating aluminum plate. For example... Figure 1As shown, it includes a lower mainboard 1, with a central support plate 21 fixedly inserted at the top center of the lower mainboard 1. The central support plate 21 allows the upper mainboard 10 and the lower mainboard 1 to extend and retract vertically, thereby allowing more of the central arc-shaped sound-dampening inner plate 4 to be added as needed to increase the sound insulation effect. The top of the outer side of the central support plate 21 is slidably inserted into the middle of the bottom of the upper mainboard 10. The upper mainboard 10 and the central support plate 21 are connected by a pin.

[0025] Please see Figure 2 A fixing plate 22 is fixedly installed at one end of the bottom of the inner wall of the lower main board 1. A middle partition 8 is fixedly sleeved in the middle of the fixing plate 22. The length of the middle partition 8 is the same as the length of the inner wall of the lower main board 1. A middle sound insulation vertical groove 3 is fixedly installed on both sides of the middle partition 8. Multiple identical horizontal damping plates 5 are fixedly installed on the inner wall of the middle sound insulation vertical groove 3. There is a gap between the horizontal damping plates 5. The outer side of the middle sound insulation vertical groove 3 contacts the outer side of the arc-shaped damping groove 6. The multiple horizontal damping plates 5 are inserted on both sides of the middle partition 8 so that when the sound wave encounters the horizontal damping plates 5 inside the middle sound insulation vertical groove 3, the sound wave is buffered, causing the sound wave energy to gradually attenuate, thereby achieving the sound insulation effect.

[0026] Please see Figure 2 Both sides of the central partition 8 are fixedly provided with arc-shaped sound-absorbing grooves 6. The arc-shaped sound-absorbing grooves 6 are designed to be wave-shaped and are evenly distributed on the upper and lower sides of the central sound-insulating vertical groove 3. The arc-shaped sound-absorbing grooves 6 are in close contact with the inner arc-shaped sound-absorbing plate 4. The sound waves will undergo multiple reflections and refractions in the air layer inside the inner arc-shaped sound-absorbing plate 4, which has a good sound absorption effect on sound waves in a wide frequency range. The inner arc-shaped sound-absorbing plate 4 is made of flame-retardant board, which can achieve corrosion resistance and high temperature resistance, prevent fire, and play a flame-retardant role, thereby increasing its safety.

[0027] Please see Figure 2 and Figure 5 The bottom of the inner wall of the arc-shaped damping groove 6 is provided with an arc-shaped damping inner plate 4. The end of the arc-shaped damping inner plate 4 away from the arc-shaped damping groove 6 is in sliding contact with the bottom of the top aluminum cover plate 12. The lower surface of the top aluminum cover plate 12 is in sliding contact with a front aluminum cover plate 13. The front aluminum cover plate 13 closes the front side of the lower main board 1 and the upper main board 10. The front aluminum cover plate 13 is set in an "L" shape. The bottom of the front aluminum cover plate 13 is slidably inserted into the inner wall of the bottom groove 2 below the lower main board 1. The middle part of the front aluminum cover plate 13 is fixedly connected to the front side of the middle partition plate 8 by the front fixing bolt 7. The slots at both ends of the top aluminum cover plate 12 are snapped into the inner wall of the snap-fit ​​groove 9 at the top of the upper main board 10. The bottom of the upper main board 10 is in sliding contact with the top of the lower main board 1.

[0028] Please see Figure 3 and Figure 4A rotating cover plate 11 is rotatably mounted on the outer side of one end of the top aluminum cover plate 12. A bolt sleeve 14 is fixedly sleeved on the middle of the rotating cover plate 11 at the end away from the top aluminum cover plate 12. A bolt rod 15 is threaded into the inner wall of the bolt sleeve 14. A main retaining ball 20 is fixedly mounted through the rotating cover plate 11 at the end of the bolt rod 15 away from the bolt sleeve 14. The outer side of the main retaining ball 20 slides in contact with a limiting ball 17. An elastic plate 16 is fixedly mounted on the outer side of the limiting ball 17. The end of the elastic plate 16 away from the limiting ball 17 is fixedly mounted on the inner wall of the slot at one end of the upper main plate 10. The elastic plate 16 is C-shaped, and the number of elastic plates 16 is [missing information]. Three elastic plates 16 are respectively disposed on the outside of three limiting balls 17. Under the action of the main locking ball 20, the limiting balls 17 push the elastic plates 16 to deform. At the same time, the resistance of the elastic plates 16 makes the three limiting balls 17 tightly locked to the outside of the main locking ball 20, preventing the main locking ball 20 from loosening after locking, and increasing the stability of the main locking ball 20 and the outer rotating cover plate 11. A limiting slide plate 19 is fixedly disposed on the outside of the elastic plate 16 on the right side. One end of the limiting slide plate 19 is fixedly disposed on the inner wall of the slot at one end of the upper main board 10. The limiting slide plate 19 restricts the position of the two outer elastic plates 16.

[0029] Please see Figure 4 A fixing ring 18 is slidably sleeved on the outer circumferential surface of the limiting ball 17. The central groove of the fixing ring 18 is set as a hole with a larger inner side and a smaller outer side. The outer diameter of the central groove of the fixing ring 18 is smaller than the diameter of the limiting ball 17. Three limiting balls 17 slidably connected in the middle of the fixing ring 18 are evenly arranged on the outer side of the main receiving ball 20. The diameter between the three limiting balls 17 in the static state is smaller than the diameter of the main receiving ball 20. The main receiving ball 20 moves towards the three limiting balls 17 under the action of the bolt rod 15, so that the limiting balls 17 slide in the central groove of the fixing ring 18. The elastic plate 16 limits the movement distance of the limiting balls 17. The position of the main receiving ball 20 is fixed by the limiting balls 17. One end of the fixing ring 18 is fixedly set on the inner wall of the slot at both ends of the upper main board 10.

[0030] The implementation principle of a sound-insulating aluminum plate in this application embodiment is as follows: According to the usage environment requirements of the sound-insulating plate, the bolt rod 15 inside the bolt sleeve 14 is rotated. Through the bolt rod 15, the main locking ball 20 is driven away from the locking effect of the three limiting balls 17. The main locking ball 20 is away from the limiting balls 17, and the limiting balls 17 move towards the center of the fixing ring 18, so that the inner side of the rotating cover plate 11 contacts the locking effect. The rotating cover plate 11 is rotated away from the upper main plate 10, so that the top aluminum cover plate 12 can be removed. By adding or removing the arc-shaped sound-absorbing inner plate 4 inside the arc-shaped sound-absorbing groove 6, different reflections and refractions occur with different numbers of air layers when the sound waves encounter different numbers of arc-shaped sound-absorbing inner plates 4, thus changing its sound insulation effect. The central sound-insulating vertical groove 3 and the horizontal sound-absorbing plate 5 are set in the middle, which can have a good sound absorption effect on sound waves in a wide frequency range. By changing the amount of internal materials, it can adapt to more usage environments.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
