Description

Technical Field

[0001] This utility model relates to the field of PVC boards, and in particular to an antistatic sound-insulating PVC board. Background Technology

[0002] PVC sheets are plastic sheets made primarily of polyvinyl chloride (PVC). They are lightweight, waterproof, moisture-proof, corrosion-resistant, and easy to process. They are widely used in building decoration, advertising display boards, furniture manufacturing, and other fields, and are low in cost and durable.

[0003] PVC panels are used in a wide range of scenarios. In building decoration, PVC panels are located in noisy environments and cannot effectively block or absorb noise, affecting the user experience. At the same time, during the installation of PVC panels, some PVC panels are reinforced with metal frames, but these can generate static electricity in dry environments, causing installation inconvenience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an antistatic sound-insulating PVC board that improves the sound absorption effect of the board and enhances its safety when touched and handled.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An antistatic sound-insulating PVC board includes a bottom plate for bottom support, a plurality of support columns fixedly connected to the top of the bottom plate, an upper cover plate fixedly connected to the top of the support columns, a middle connecting plate fixedly connected to the middle of the support columns, a sound-insulating blocking component installed on the inner side of the middle connecting plate to increase the sound insulation effect of the PVC board and to allow external sound to enter, and an electrostatic traction component installed on the outer side of the top of the upper cover plate to cancel out static electricity.

[0007] Furthermore, the electrostatic traction assembly includes an electrostatic adsorption plate fixed at the top of the upper cover plate, and a plurality of electrostatic transmission rods are uniformly fixedly connected to the bottom end of the electrostatic adsorption plate, with the outer sides of the electrostatic transmission rods penetrating the inner wall of the upper cover plate respectively.

[0008] Furthermore, the sound insulation barrier assembly includes a sound insulation I-shaped cotton layer fixed inside the middle connecting plate. Multiple cavity slots are opened on both the upper and lower sides of the sound insulation I-shaped cotton layer, and the cavity slots are filled with multiple sound-absorbing foam particles.

[0009] Furthermore, a protective cloth layer is fixedly connected to the outer side of each cavity slot to provide blocking protection for the cavity slot.

[0010] Furthermore, the upper cover plate has multiple honeycomb holes inside.

[0011] Furthermore, insulating rubber pads are fixedly connected to both outer peripheries of the middle layer connecting plate, and the outer sides of the insulating rubber pads are respectively fixedly connected to the inner sides of the upper cover plate and the bottom plate.

[0012] Furthermore, the outer surface of the electrostatic transfer rod passes through the upper insulating pad and the middle connecting plate and is inserted into the interior of the insulating pad.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the noisy sound passes through the upper cover plate and enters the interior of the sound insulation cotton layer. The sound is absorbed by the sound-absorbing foam particles inside the multiple cavity slots. Through double-layer absorption, the sound insulation and absorption effect of the board is improved, thereby improving the user experience of the board.

[0015] 2. In this utility model, the static electricity generated by drying is transferred to the interior of the board through multiple static electricity transfer rods at the bottom by the electrostatic adsorption plate, and the static electricity is canceled out by the double-layer middle connecting plate on the inner side, thereby improving the safety of the board when touching and picking it up.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model provides an antistatic sound-insulating PVC board, comprising a bottom plate 1 for bottom support, a plurality of support columns 12 fixedly connected to the top of the bottom plate 1, an upper cover plate 2 fixedly connected to the top of the support columns 12, a middle connecting plate 6 fixedly connected to the middle of the support columns 12, a sound-insulating blocking component installed on the inner side of the middle connecting plate 6 to increase the sound insulation effect of the PVC board and to allow external sound to enter, an electrostatic traction component installed on the outer side of the top of the upper cover plate 2 to cancel out static electricity, the sound-insulating blocking component comprising a sound-insulating I-shaped cotton layer 7 fixedly located on the inner side of the middle connecting plate 6, a plurality of cavity slots 11 opened on both the upper and lower sides of the sound-insulating I-shaped cotton layer 7, a plurality of sound-absorbing foam particles 10 filled inside the cavity slots 11, a protective cloth layer 9 fixedly connected to the outer side of the cavity slots 11 to block and protect the cavity slots 11, and a plurality of honeycomb holes 3 opened inside the upper cover plate 2.

[0024] In noisy environments, external sound waves enter the sound insulation system through the honeycomb holes 3 on the surface of the upper cover plate 2. They are first initially blocked and absorbed by the outer side of the sound insulation cotton layer 7. Subsequently, the sound waves enter the multi-cavity structure of the cavity slot 11 for secondary pre-processing. After the sound waves penetrate the upper sound insulation cotton layer 7, they continue to pass through the composite sound absorption layer composed of the lower sound insulation cotton layer 7 and the sound-absorbing foam particles 10, achieving deep attenuation. This double-layer sound absorption mechanism significantly improves the noise absorption performance of the board through multi-level sound energy conversion and dissipation, effectively improving the user experience in complex acoustic environments.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The electrostatic traction assembly includes an electrostatic adsorption plate 4 fixed at the top of the upper cover plate 2. Multiple electrostatic transmission rods 8 are uniformly fixedly connected to the bottom end of the electrostatic adsorption plate 4. The outer sides of the electrostatic transmission rods 8 penetrate the inner wall of the upper cover plate 2. Insulating pads 5 are fixedly connected to both sides of the middle connecting plate 6. The outer sides of the insulating pads 5 are respectively fixedly connected to the inner sides of the upper cover plate 2 and the bottom plate 1. The outer sides of the electrostatic transmission rods 8 penetrate the upper insulating pads 5 and the middle connecting plate 6 and are inserted into the interior of the insulating pads 5.

[0026] When the board is installed in a dry environment, static electricity may accumulate due to biological contact. The board uses an electrostatic adsorption plate 4 to conduct the generated static charge to the electrostatic transfer rods 8 distributed in an array on the inner side, forming a directional charge transfer path. The electrostatic transfer rods 8 penetrate through the upper insulating pad 5 and extend into the interior of the lower insulating pad 5, constructing a complete static dissipation channel. This design achieves effective conduction and neutralization of static charge, significantly improving the antistatic performance of the board during installation and handling, and ensuring safe and reliable operation.

[0027] Working principle: When the PVC board is in a noisy environment, external sound enters the sound insulation cotton layer 7 through multiple honeycomb holes 3 on the surface of the upper cover plate 2. The outer side of the sound insulation cotton layer 7 blocks and absorbs the noise, and the sound enters the cavity slot 11. The sound is then pre-processed again through multiple cavity slots 11 inside the cavity slot 11. When the sound passes through the upper layer of the sound insulation cotton layer 7 and is transmitted to the lower layer of the sound insulation cotton layer 7, the sound is further absorbed by the lower layer of the sound insulation cotton layer 7 and the sound-absorbing foam particles 10, thereby improving the absorption of noise by the board. At the same time, when the board is installed, in a dry environment, a certain amount of static electricity is generated due to contact with biological materials. The static electricity is transmitted to multiple static electricity transmission rods 8 on the inner side through the static electricity adsorption plate 4, thereby transmitting the static electricity to the interior of the board. The static electricity transmission rods 8 penetrate the upper insulating pad 5 and are located inside the lower insulating pad 5, discharging the transmitted static electricity into them, thereby canceling the static electricity and improving the safety of the board.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
