[0021] 6. The present invention pulls the pull rod and utilizes the sliding cooperation between the slider and the slide rod, the hinged cooperation between the slider and the pull rod and the connecting rod, and the sliding cooperation between the guide block and the guide groove, so that the two groups of pins can be driven to move back to each other at the same time. At this time, the spring will be compressed. By inserting the plug block on the other sound-absorbing panel body into the slot and releasing the pull rod, the two groups of pins will automatically insert into the pin holes on the plug block under the rebound action of the spring itself, thereby realizing the rapid splicing of the sound-absorbing panel body. Conversely, the sound-absorbing panel body can be quickly disassembled, which is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example 1:

[0032] Please combine Figure 1-6A composite metal sound-absorbing panel of this embodiment includes an aluminum panel 1. A surface treatment layer 2 for improving corrosion resistance is provided on the outside of the aluminum panel 1. A sound insulation layer 3 for improving sound absorption efficiency and sound insulation effect is provided on the outside of the surface treatment layer 2. A surface layer 4 is provided on the outside of the sound insulation layer 3. A decorative layer 5 for improving the decorative performance of the panel is sprayed on the outside of the surface layer 4. The aluminum panel 1, the sound insulation layer 3 and the surface layer 4 can form a complete sound-absorbing panel body. Two groups of slots 13 are symmetrically opened on one side of the sound-absorbing panel body. Two groups of convex-shaped plug blocks 14 are symmetrically fixedly connected on the other side of the sound-absorbing panel body. A slide rod 15 is fixedly connected to the inside of the slot 13. The outside of the slide rod 15 is symmetrically slidably connected to the outside of the slide rod There are two groups of sliders 16, one side of the slider 16 is fixedly connected to a guide block 17, the inner wall of the slot 13 is provided with a guide groove corresponding to the position of the guide block 17, and the guide groove is slidably connected to the guide block 17 on the same side, and the slider 16 is also fixedly connected to a pin rod 18. The outside of both sides of the slide rod 15 is provided with a spring 19, and the two ends of the spring 19 are respectively fixedly connected to the slider 16 and the inner wall of the slot 13. A pull rod 20 is slidably connected to the sound-absorbing board body, and two groups of connecting rods 21 are symmetrically hinged between the pull rod 20 and the slider 16 through a hinge. A strip groove for its movement is provided on the sound-absorbing board body corresponding to the position of the connecting rod 21, and pin holes adapted to the pin rod 18 are symmetrically provided on the insert block 14. The interior of the aluminum plate 1 is opened There is a cavity 6 for reflecting sound, and the outside of the aluminum plate 1 is evenly provided with a sound-absorbing hole 7 for allowing sound to enter, and the sound-absorbing hole 7 is connected to the cavity 6, and the diameter of the sound-absorbing hole 7 is 4-6mm. The sound-absorbing hole 28 is provided at the position corresponding to the sound-absorbing hole 7 on the sound insulation layer 3 and the surface plate 4, and the diameter of the sound-absorbing hole 28 is consistent with the diameter of the sound-absorbing hole 7. The inside of the sound-absorbing hole 28 is fixedly connected with a thin wire 9 made of ultra-high molecular weight polyethylene fiber material, and the end of the thin wire 9 is fixedly connected with a micro airbag 10 made of nylon material. The surface treatment layer 2 is an anodized layer with a thickness of 7-15μm. The sound insulation layer 3 is made of polyester fiber material, which is environmentally friendly and safe. It is safe, non-toxic and harmless, suitable for indoor sound insulation, and it also has good moisture-proof, mildew-proof and aging-resistant properties. It is not easy to deform or perform attenuated after long-term use. The thickness of the sound insulation layer 3 is 25-50mm, and the panel layer 4 is made of wood. The thickness of the panel layer 4 is 0.8-2mm. The interior of the cavity 6 is evenly provided with support columns 11 with square side structures for preventing the aluminum plate 1 from easily sinking. The size of the support column 11 is 1cm×1cm×2cm, and the support column 11 is made of metal aluminum with a solid structure. The support column 11 is fixedly connected to the inside of the aluminum plate 1 by welding, and its surface area is larger than that of a cylinder with a bottom circle diameter of 1cm and a height of 2cm.

[0033] The implementation principle of a composite metal sound-absorbing panel in the embodiment of the present application is as follows: during the propagation of sound, part of the sound will be absorbed by the sound insulation layer 3, and the other part will enter the second sound-absorbing hole 8. Since the sound will drive the air flow during the propagation, the flowing air will cause the micro airbag 10 suspended by the thin wire 9 to shake, and at this time, the accumulated and adhered dust can be scattered, thereby preventing the sound-absorbing hole from being blocked. This effectively avoids the problem that the existing sound-absorbing panel is difficult to automatically prevent the accumulation of dust inside the sound-absorbing hole, which makes the sound-absorbing hole easily blocked by dust, thereby easily affecting the sound elimination effect of the sound-absorbing panel. In addition, the thin wire 9 and the micro airbag 10 are made of ultra-high molecular weight polyethylene fiber material and nylon material respectively, so that they can avoid breakage or damage, thereby extending the service life of the two. After passing through the second sound-absorbing hole 8 and the first sound-absorbing hole 7, the sound will enter the cavity 6, and then the sound will be reflected inside the cavity 6 and consumed in the form of heat. Through the support column 11 evenly fixedly connected to the inside of the aluminum plate 1, The contact area between the aluminum plate 1 and the sound can be increased, thereby increasing the number of reflections of the sound inside the aluminum plate 1, thereby improving the sound elimination effect. At the same time, by evenly fixing the support column 11 connected to the inside of the aluminum plate 1, the hollow structure of the aluminum plate 1 can be supported from the inside, thereby preventing it from being easily dented when hit, thereby protecting the aluminum plate 1. By pulling the pull rod 20 and utilizing the sliding fit between the slider 16 and the slide bar 15, the slider 16 and the pull rod 20 The hinged connection with the connecting rod 21 and the sliding connection between the guide block 17 and the guide groove enable the two groups of pins 18 to move back to each other at the same time. At this time, the spring 19 will be compressed. By inserting the plug block 14 on the other sound-absorbing panel body into the slot 13 and releasing the pull rod 20, the two groups of pins 18 will automatically insert into the pin holes on the plug block 14 under the rebound effect of the spring 19 itself, thereby realizing the rapid splicing of the sound-absorbing panel body. Conversely, the sound-absorbing panel body can be quickly disassembled, which is highly practical.

[0034] Example 2:

[0035] Based on Example 1, this embodiment is further improved in that: the inner wall of the cavity 6 and the outside of the support column 11 are fixedly connected with a sound-absorbing felt 12, and the thickness of the sound-absorbing felt 12 is 1.2-5 mm. When the sound reaches the surface of the sound-absorbing felt 12, part of it will be reflected, part will penetrate the material, and the other part will be absorbed by the material itself. The absorbed sound energy is due to the friction between the material and the surrounding medium during vibration or sound propagation, which causes the sound energy to be gradually converted into heat energy, thereby effectively dissipating the sound energy and achieving the effect of sound absorption and noise reduction.

[0036] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
