Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation cotton, and specifically relates to a combined sound insulation cotton. Background Technique

[0002] The sound insulation cotton is made of fiber porous sound insulation materials. The sound insulation mechanism of the sound insulation cotton is that there are a large number of tiny and connected pores inside the material. Sound waves can penetrate deep into the material along these pores and convert sound energy into heat energy through friction with the material. In order to ensure the sound insulation of the wall, it is usually necessary to install corresponding sound insulation cotton on the wall, making the use of sound insulation cotton popular.

[0003] Most of the existing wall sound insulation cottons are combined sound insulation cottons. The inner layer of the combined sound insulation cotton uses high-density rock wool to isolate low-frequency noise, and the outer layer is covered with polyester fiber cotton to absorb medium-frequency sound waves, thereby effectively reducing sound wave reflection and improving the sound insulation effect. However, some finished products of the combined sound insulation cotton cannot change the thickness according to the customer's needs, and at the same time, they cannot adjust the thickness of the sound insulation cotton according to different use environments, resulting in poor compatibility and reduced practicability. Therefore, in view of the above problems, we have proposed a combined sound insulation cotton. Summary of the Invention

The device can stack the combined sound insulation cotton as a whole, and then change the overall thickness of the combined sound insulation cotton according to customer needs, making the combined sound insulation cotton more compatible as a whole, capable of adjusting the thickness of the combined sound insulation cotton according to different use environments, and improving the practicality; the elastic rubber sleeve 8 is fixedly connected inside the card slot 7, the elastic rubber plug 9 is provided inside the card slot 7, the internal thread sleeve 10 is fixedly connected to the inner side of the lower end of the fixed frame 6, the sealing gasket 11 is fixedly connected to the lower end surface of the fixed frame 6, the external thread plate 12 is detachably threadedly connected to the inside of the internal thread sleeve 10, the clamping column 13 is fixedly connected to the lower end of the external thread plate 12, and the damping sleeve 14 is fixedly connected to the outside of the clamping column 13.

[0024] Working Process: During operation, the polyester fiber cotton body 1, rock wool body 2, and fixed frame 6 constitute a combined sound insulation cotton system. An air-insulating layer 3 is provided inside the rock wool body 2, which hinders noise transmission. Sound-insulating pipes 4 and sound-insulating panels 5 are installed inside the rock wool body 2. The sound-insulating panel 5 increases the noise transmission path through the sound-insulating pipes 4 and also blocks and dissipates noise energy, effectively isolating noise. When adjusting the thickness of the combined sound insulation cotton system as needed, first pull the elastic rubber plug 9 outwards and remove it, opening the slot 7. Then, connect the external threaded plate 12 and the internal threaded sleeve 10 via threads, installing the external threaded plate 12 on the lower inner side of the fixed frame 6. Next, insert the locking post 13, fixedly connected to the lower end of the external threaded plate 12, into the slot 7 opened at the upper end of another fixed frame 6, causing the locking post 13 to compress the elastic rubber sleeve 8 through the damping sleeve 14. The elastic rubber sleeve 8 deforms elastically, fixing the locking post 13 to another fixed frame 6, thus completing the stacking of two combined sound insulation cottons and adjusting the thickness of the sound insulation cotton. The damping sleeve 14 increases the friction between the locking post 13 and the elastic rubber sleeve 8, allowing the locking post 13 to be better installed in the slot 7 and reducing shaking during installation. At the same time, the lower end face of the sealing gasket 11 fits against the upper end face of another fixed frame 6 located at the lower end, reducing the gap between the two fixed frames 6 and making the two combined sound insulation cottons fit more tightly. This device can stack the combined sound insulation cotton as a whole, and then change the overall thickness of the combined sound insulation cotton according to customer needs, making the overall compatibility of the combined sound insulation cotton stronger. It can adjust the thickness of the combined sound insulation cotton according to different usage environments, improving practicality. When storing the combined sound insulation cotton, the elastic rubber plug 9 is inserted into the slot 7 to reduce dust entry.
