[0009] Preferably, two fastening blocks are symmetrically arranged on the front and rear sides of the support side strip. The two fastening blocks are slidably connected with the support side strip. One end of the two fastening blocks extends to the outside of the slider and is in fit connection with the fixed side strip. The other ends of the two fastening blocks are movably connected by springs, and adjusting bolts are threadedly installed on the side of the slider surface.

[0010] Preferably, the adjusting bolt is threadedly connected to the slider, and a nut is provided at one end of the adjusting bolt extending to the outside of the slider. An inclined surface is provided at the other end of the adjusting bolt and is in fitting connection with the fastening block.

[0011] Preferably, trapezoidal grooves are formed on both the front and rear sides of the surface of the supporting edge strip. A clamping block is fixedly installed on the surface of the screen panel, and the clamping block is slidably connected to the trapezoidal groove.

[0012] Preferably, the left and right ends of the noise reduction body are respectively fixedly connected to the supporting edge strip, and sound insulation filler cotton is arranged inside the noise reduction body. Beneficial effects

[0013] The present utility model provides a noise reduction screen adjusting structure. Compared with the prior art, the following beneficial effects are achieved:

[0014] In this noise reduction screen adjusting structure, by providing a fixed edge strip, a supporting edge strip, a noise reduction body, etc., the diamond structure of the noise reduction body has good stretchability. When the supporting edge strip moves, it can drive the noise reduction body to perform telescopic activities to adjust the width of the screen. At the same time, the connection between the slider and the slide rail groove facilitates the installation of the supporting edge strip on the fixed edge strip and the adjustment of the positions of multiple supporting edge strips. After installation, the user rotates the adjusting bolt so that the end of the adjusting bolt contacts one end of the fastening block and pushes the fastening block to move outward to fit with the fixed edge strip, realizing the limit fixation of the slider. Thus, when moving, by adjusting the length of the fixed edge strip, different size requirements can be adapted, and the overall noise reduction screen can be adjusted for use, improving functionality.

[0021] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. 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.

[0022] Please refer to Figures 1-5 , the present utility model provides a technical solution: a noise reduction screen adjustment structure, including an installation frame 1, a screen panel 2 is arranged on the surface of the installation frame 1, and a noise reduction body 3 is arranged inside the installation frame 1. Different decorative patterns can be designed on the screen panel 2 to increase the beauty of the noise reduction screen;

[0023] The installation frame 1 is composed of a fixed side strip 11 and a support side strip 12. There are two fixed side strips 11 symmetrically arranged. A support side strip 12 is arranged between the two fixed side strips 11. The support side strips 12 are evenly distributed at equal intervals in three. A fastening block 13 is arranged on the surface of the support side strip 12. A slide rail groove 111 is opened on the surface of the fixed side strip 11. Both the upper and lower ends of the support side strip 12 are fixedly connected with a slider 121. The slider 121 is slidably connected with the slide rail groove 111. The slider 121 is designed in a T-shaped structure. Two fastening blocks 13 are symmetrically arranged on the front and rear sides of the support side strip 12. The two fastening blocks 13 are slidably connected with the support side strip 12. One end of the two fastening blocks 13 extends to the outside of the slider 121 and is in fit connection with the fixed side strip 11. The other ends of the two fastening blocks 13 are movably connected by a spring. A regulating bolt 131 is threadedly installed on the side of the surface of the slider 121. The regulating bolt 131 is threadedly connected with the slider 121. One end of the regulating bolt 131 extends to the outside of the slider 121 and is provided with a nut. The other end of the regulating bolt 131 is provided with an inclined surface and is in fit connection with the fastening block 13. Trapezoidal grooves 14 are opened on the front and rear sides of the surface of the support side strip 12. A clamping block is fixedly installed on the surface of the screen panel 2. The clamping block is slidably connected with the trapezoidal groove 14. The connection between the slider 121 and the slide rail groove 111 facilitates the installation of the support side strip 12 on the fixed side strip 11 and the adjustment of the positions of multiple support side strips 12. After installation, the operator rotates the regulating bolt 131 so that the end of the regulating bolt 131 contacts one end of the fastening block 13 and pushes the fastening block 13 to move outward and fit with the fixed side strip 11, realizing the limit fixation of the slider 121. Thus, when moving, by adjusting the length of the fixed side strip 11, different size requirements can be adapted;

[0024] There are two noise reduction bodies 3 provided, and the two noise reduction bodies 3 are adapted to the supporting edge strips 12. The noise reduction body 3 is composed of a plurality of rhombic structures. The left and right ends of the noise reduction body 3 are respectively fixedly connected to the supporting edge strips 12. A sound insulation filling cotton is arranged inside the noise reduction body 3. The noise reduction body 3 is composed of rhombic structures stitched with cloth material and filled with sound insulation filling cotton therein, which can achieve the functions of noise reduction and sound absorption. The rhombic structure has a certain stretchability, so that by moving the supporting edge strip 12, the noise reduction body 3 can be driven to move, adapting to screens of different sizes.

[0025] During operation, the fixed edge strip 11 is fixed to the installation surface, and then the supporting edge strip 12 is installed on the fixed edge strip 11, so that the slider 121 enters the slide rail groove 111. Then the operator rotates the adjusting bolt 131, so that the end of the adjusting bolt 131 contacts one end of the fastening block 13 and pushes the fastening block 13 to move outward and fit with the fixed edge strip 11, realizing the limit fixation of the slider 121. Finally, the screen panel 2 is installed on the surface through the engagement of the engaging block and the trapezoidal groove 14. At the same time, the connection between the slider 121 and the slide rail groove 111 facilitates the installation of the supporting edge strip 12 on the fixed edge strip 11 and the adjustment of the positions of multiple supporting edge strips 12.

[0026] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art in the art.
