Detailed Embodiment

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] The embodiments of the present utility model disclose a sound-insulating and anti-collision composite multi-layer board.

[0021] According to the attached Figures 1-4 As shown, it includes a plurality of connecting substrate units 1. A main board unit 2 is connected between the plurality of connecting substrate units 1. The main board unit 2 includes a main board body 21, a first partition 22, a second partition 23 and a plurality of reinforcing components 24. The main board body 21 is arranged between the first partition 22 and the second partition 23. The first partition 22 is arranged on the top of the main board body 21. The second partition 23 is arranged at the bottom of the second partition 23. The reinforcing components 24 are arranged between the main board body 21, the first partition 22 and the second partition 23.

[0022] Furthermore, the main board body 21 is adhesively connected to the first partition 22 and the second partition 23.

[0023] Furthermore, the reinforcing component 24 includes a reinforcing screw 241 and a tightening member 242. The reinforcing screw 241 passes through the first partition 22 and the main board body 21 and is connected to the second partition 23. The tightening member 242 is fixedly connected to the top of the reinforcing screw 241. By rotating the tightening member 242, the reinforcing screw 241 is threadedly connected and fixed to the first partition 22 and the second partition 23, so that the reinforcing screw 241 supports between the first partition 22 and the second partition 23.

[0024] Furthermore, the connecting substrate unit 1 includes a substrate body 11, a slider 12 and a chute 13. A plurality of substrate bodies 11 are respectively adhesively connected to the first partition 22 and the second partition 23. The slider 12 is fixedly connected to one side of the substrate body 11. The chute 13 is opened on the other side of the substrate body 11.

[0025] Furthermore, a plurality of through holes 111 are opened inside the substrate body 11. By providing the through holes 111, not only the weight of the substrate body 11 is lighter, but also when the composite multi-layer board is installed, the fasteners are connected between the substrate body 11 and the installation foundation in the through holes 111.

[0026] Furthermore, a plurality of honeycomb holes 211 are opened inside the main board body 21. The plurality of honeycomb holes 211 form a honeycomb structure. The plurality of honeycomb holes 211 are closed structures, and the inside is filled with air and does not circulate, having good sound insulation performance.

[0027] Furthermore, a plurality of grooves 221 are formed in the first partition plate 22. The tightening member 242 is rotatably connected in the groove 221, and the tightening member 242 is flush with the upper surface of the first partition plate 22, which will not affect the adhesive connection between the first partition plate 22 and the substrate body 11. A plurality of first threaded holes 222 are formed at the bottom of the plurality of grooves 221, and the reinforcing screw 241 is threadedly connected in the first threaded hole 222.

[0028] Furthermore, a plurality of second threaded holes 231 are formed in the second partition plate 23, and the bottom of the reinforcing screw 241 is threadedly connected in the second threaded hole 231.

[0029] Working principle: By horizontally arranging a plurality of through holes 111 in the substrate body 11 and vertically arranging a plurality of honeycomb holes 211 in the main board body 21, when the composite board is impacted by an external force, the external force can be dispersed and transmitted. When the external force is transmitted to the first partition plate 22, through a plurality of reinforcing screws 241 in the main board body 21, most of the external force is transmitted to the second partition plate 23 through the plurality of reinforcing screws 241. At the same time, the vertical arrangement of the honeycomb holes 211 can disperse and transmit the external force, greatly reducing the external force received by the honeycomb structure in the main board body 21. The external force transmitted to the second partition plate 23 is then dispersed and transmitted through a plurality of through holes 111 in the substrate body 11, avoiding damage and deformation of the composite board caused by local external force concentration, improving the impact resistance of the composite board. Moreover, the plurality of honeycomb holes 211 are closed structures, filled with air and not communicating with each other, having good sound insulation performance.

[0030] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only includes an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
