Description

Technical Field

[0001] This utility model relates to the field of color steel plate technology, and in particular to a sound insulation and noise reduction structure for color steel plates. Background Technology

[0002] Color-coated steel sheet, also known as color-coated steel sheet, is a type of sheet material made by coating cold-rolled steel sheet with one or more layers of organic coating and then baking and curing it. With the continuous advancement of production technology, people have higher and higher requirements for color-coated steel sheets, and the technology of noise-reducing color-coated steel sheets has also been developed. By adopting special materials and structural designs, such as perforated color-coated steel sheets and composite rock wool core materials, it can effectively reduce noise transmission and meet the sound insulation needs of different places.

[0003] Existing color steel panels with sound insulation and noise reduction functions are usually connected to the sound insulation cotton with glue. Under the influence of wind and sun outdoors, the glue will age and lose some of its adhesiveness. In some windy weather, the sound insulation cotton and the color steel panel are easily blown apart by strong winds, so while the color steel panel can achieve the purpose of noise reduction and sound insulation, it also poses certain safety hazards.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A sound insulation and noise reduction structure for color steel plates includes a color steel plate body 1 and sound insulation cotton 2. The sound insulation cotton 2 is fixedly connected to the color steel plate body 1. The sound insulation cotton 2 is existing technology and is usually made of rock wool or other similar insulation materials. These materials have good thermal insulation and sound absorption and sound insulation effects. Two pressing components are installed on the color steel plate body 1. The pressing components include a crossbar 10, a fixing chamber 11, a round rod 12, an adjusting plate 13, and a pressing plate 15. The fixing chamber 11 is fixedly connected to the color steel plate body 1. The crossbar 10 is slidably connected to the fixing chamber 11. The fixing chamber 11 has a moving hole. The crossbar 10 is slidably connected in the moving hole. The round rod 12 passes through... The rod passes through the fixed chamber 11 and is slidably connected to the fixed chamber 11. The adjusting plate 13 is slidably connected to the round rod 12. Two extrusion plates 15 are respectively fixedly connected to the two ends of the crossbar 10. The extrusion plates 15 are set in a right-angled trapezoid to facilitate the normal operation of the extrusion work. A pressure block 16 is fixedly connected to the outer surface of the round rod 12 near the extrusion plate 15. The pressure block 16 is set in an isosceles trapezoid. The extrusion plate 15 is slidably connected to the pressure block 16. The inclined surface of the extrusion plate 15 is in contact with the inclined surface of the pressure block 16. The extrusion plate 15 is slidably connected to the fixed chamber 11. One end of the round rod 12 is provided with a disc. A straight spring 14 is fixedly connected between the disc and the fixed chamber 11.

[0023] A rotating chamber 3 is fixedly connected to the main body 1 of the color steel plate. A rotating shaft 4 is rotatably connected inside the rotating chamber 3. A wind-facing plate 5 is sleeved on the outer surface of the rotating shaft 4. The wind-facing plate 5 is made of lightweight material and is easy to be blown by the wind. Spur gears 6 are fixedly connected to both ends of the rotating shaft 4. Irregularly shaped plates 8 are fixedly connected to both ends of the rotating chamber 3. Two rack plates 7 are slidably connected to the inner wall of the rotating chamber 3. A return spring 9 is fixedly connected between the rack plate 7 and the irregularly shaped plate 8. The function of the return spring 9 is to ensure that the wind-facing plate 5 is not subjected to strong wind. At the same time, the cooperation of the two return springs 9 and the irregularly shaped plate 8 ensures that the adjusting plate 13 can work normally and drive the rack plates regardless of the direction of the wind. 7. Reset, thereby resetting the windshield 5 through the spur gear 6 and the rotating shaft 4 to ensure normal operation in the next operation. The rack plate 7 meshes with the spur gear 6 and is fixedly connected to the crossbar 10. A square plate 17 is fixedly connected to the adjusting plate 13. A straight rod 18 is slidably connected to the square plate 17. A pull plate 20 is fixedly connected to one end of the straight rod 18. A limit ring 19 is fixedly connected to the outer surface of the round rod 12. Multiple limit holes are opened on the outer surface of the limit ring 19. The size of the limit holes is slightly larger than the radius of the straight rod 18. The straight rod 18 is slidably connected in the limit holes. A rigid spring is provided between the square plate 17 and the pull plate 20. The rigid spring has a large elastic force and will not be easily pulled.

[0024] In this invention, the sound insulation cotton 2 is first fixed to the color steel plate body 1. Then, the pull plate 20 is pulled, causing the straight rod 18 to disengage from the limiting hole on the limiting ring 19. This causes the straight rod 18 to lose its limiting effect on the limiting ring 19 and the adjusting plate 13. At this point, the adjusting plate 13 is slid, allowing it to move and fit tightly against the sound insulation cotton 2. When the pull plate 20 is released, it resets under the action of a rigid spring, pushing the straight rod 18 back into the limiting hole of the limiting ring 19, thus completing the limiting and fixing effect on the adjusting plate 13. This ensures that the adjusting plate 13 can fit tightly against the sound insulation cotton 2. The fact that the adjusting plate 13 can slide freely on the round rod 12 allows it to adapt to sound insulation cotton 2 of different thicknesses. The fixing position can be adjusted according to the different thicknesses of the sound insulation cotton 2, thereby improving the overall applicability of the structure and facilitating the later recycling and replacement of the sound insulation cotton 2.

[0025] When encountering strong winds, the strong winds immediately act on the color steel plate body 1 and the windward plate 5. The windward plate 5 rotates under the force of the strong wind, which drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the spur gears 6 at both ends to rotate. The rotation of the spur gears 6 drives the rack plate 7 to move. The movement of the rack plate 7 drives the crossbar 10 to move. The movement of the crossbar 10 drives the pressing plate 15 to move. The movement of the pressing plate 15 drives the pressure block 16 to move upward. The upward movement of the pressure block 16 drives the round rod 12 to move upward. The upward movement of the round rod 12 drives the pull plate 20 to move upward through the limit ring 19. Thus, the pull plate 20 presses the sound insulation cotton 2 tightly, preventing the sound insulation cotton 2 from being blown off by the strong wind. This gives the color steel plate body 1 a certain degree of resistance to strong winds, improves the service life of the color steel plate body 1 and the sound insulation cotton 2, reduces the impact of glue aging, and improves the safety performance of the color steel plate body 1.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
