[0018] like Figure 1 and Figure 2As shown, a bottom-enhanced noise-reducing windproof screen includes a vertical plate 1, which is a rectangular hollow setting with an opening on one side. A connecting notch 2 is opened in the middle of the upper and lower sides of the vertical plate 1, and the connecting notch 2 is symmetrically arranged in the upper and lower directions. It also includes a connecting component 3 and a flip adjustment component 4. The connecting component 3 is fixedly connected to the two side walls of the vertical plate 1, and the vertical plates 1 are hinged and connected one by one through the connecting component 3. The flip adjustment component 4 is movably connected to the upper and lower sides of the vertical plate 1, and is used for sound insulation protection of the upper and lower sides of the vertical plate 1.

[0019] like Figure 1-4 As shown, in order to hinge the vertical panels 1 one by one and assemble them into a windscreen, the connecting assembly 3 includes a positioning ring 5, a positioning block 6 and a connecting ring 7. The positioning ring 5 and the positioning block 6 are fixedly connected to the upper and lower sides of the side wall of the vertical panel 1. The positioning ring 5 and the positioning block 6 are arranged at intervals. A connecting groove 8 is formed between the positioning ring 5 and the positioning block 6. A connecting hole 9 is opened inside the positioning block 6. The connecting hole 9 is coaxially arranged with the positioning ring 5. The connecting ring 7 is fixedly connected to the side wall of the vertical panel 1 away from the positioning ring 5. The height position of the connecting ring 7 matches that of the connecting groove 8. The connecting ring 7 is inserted into the connecting groove 8 of the adjacent vertical panel 1. The adjacent vertical panels 1 are hingedly connected by bolts that penetrate the positioning ring 5, the connecting ring 7 and the connecting hole 9 in sequence.

[0020] like Figure 1 As shown, in order to create a quiet recording environment and increase the sound insulation effect of the windscreen, the upper and lower sides of the vertical board 1 are soundproofed and protected. The flip adjustment component 4 includes a rotating shaft 10 and an adjusting flap 11. The rotating shaft 10 is fixed in the connecting notch 2. One end of the adjusting flap 11 is rotatably connected to the outer wall of the rotating shaft 10. The adjusting flap 11 is arranged in a hollow isosceles triangle with one side open. The adjusting flap 11 has the same opening direction as the vertical board 1. The adjusting flap 11 is flipped on the upper and lower sides of the vertical board 1 through the rotating shaft 10, and forms a quiet recording environment with the inside of the vertical board 1.

[0021] like Figure 2-4 As shown, in order to facilitate the adjustment of the position and angle of the windbreak and to limit the bottom of the windbreak, a connecting pipe 13 is passed through the middle of the vertical plate 1, and a connecting plate 14 is provided at the bottom of the side wall of the vertical plate 1 away from the opening. The connecting plate 14 is L-shaped, and a mounting hole 15 is provided on the connecting plate 14 parallel to one side of the vertical plate 1. The mounting hole 15 corresponds to the hole position of the connecting pipe 13. The connecting plate 14 is perpendicular to the vertical plate 1 and a slide groove 16 is provided in the middle of the bottom. The connecting plate 14 is fixed to the outside of the vertical plate 1 by bolts passing through the mounting hole 15 and the connecting pipe 13. Bolts are inserted into the slide groove 16 at the bottom of the connecting plate 14 to limit the connecting plate 14, so that the connecting plate 14 can move and adjust its angle under the limiting action of the bolts.

[0022] Among them, a through hole 12 is opened in the vertical plate 1 and the adjustment flap 11. The through hole 12 is arranged in a rectangular shape and is used to absorb external noise so that the noise is absorbed by the silent cotton in the vertical plate 1 and the symmetrical adjustment flap 11.

[0023] When in use, the operator fills the opening of the flap 11 and the vertical board 1 with mute cotton, inserts the connecting ring 7 into the connecting groove 8 of the adjacent vertical board 1, and hinges the adjacent vertical boards 1 by bolts that penetrate the positioning ring 5, the connecting ring 7 and the connecting hole 9 in sequence. The flap 11 is adjusted to flip on the upper and lower sides of the vertical board 1 through the rotating shaft 10, and forms a quiet recording environment with the interior of the vertical board 1;

[0024] When in use, the connecting plate 14 is limitedly connected so that the bolts pass through the slide slot 16 and are connected to the ground or the supporting device, so that the connecting plate 14 can be moved and adjusted under the limiting action of the slide slot 16 and the bolts to achieve the position and angle movement adjustment of the windscreen.
