Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation cabins, in particular to a lightweight prefabricated board sound insulation cabin which can be quickly disassembled and assembled. Background Art

[0002] Soundproof cabins, also known as soundproof barriers, are one of the methods to reduce noise and are the most effective way to mitigate noise from roads, railways and industrial noise sources. Most of them are used on roads, and soundproof barriers are also built outside the construction sites to reduce noise and dust nuisance to pedestrians or nearby. As people have higher and higher requirements for office environment, soundproof barriers are gradually being used in office buildings. In the prior art, most soundproof cabins are integrated designs, but the integrated design will be inconvenient to transport. Therefore, the number of soundproof cabins assembled with prefabricated panels is gradually increasing. However, most traditional assembled soundproof cabins are fixed with bolts, which is inconvenient to install. At the same time, the distance between the two side panels of the soundproof cabin cannot be adjusted. When the glass in the soundproof cabin is damaged, glass of different widths cannot be installed.

[0003] For example, a lightweight, quickly disassembled and assembled prefabricated soundproof cabin (publication number: CN215857329U) disclosed in a Chinese patent document, although this patent achieves adjustment of the distance between the side panels by rotating a double-headed threaded rod, thereby achieving installation of glass of different widths, but the manual operation is cumbersome and labor-intensive, and after the side panels are adjusted, the protrusions need to be removed by bolts, and then re-fixed according to the adjusted position of the side panels. This process requires repeated disassembly and assembly of the bolts, which greatly increases the installation time, thereby reducing the disassembly and assembly efficiency. Utility Model Content

[0021] One end of the moving block 6 is provided with a moving adjustment device, and the moving adjustment device includes a fixed plug block 7 , and the lower surface of the fixed plug block 7 is fixedly connected to one end of the moving block 6 .

[0022] Furthermore, the lower surfaces of the two fixed blocks 7 are in contact with the upper surface of the mounting base 1, the outer surface of the bidirectional screw 4 is fixedly sleeved with a worm gear 71, and the inner bottom wall of the mounting base 1 is fixedly mounted with a servo motor 72. The guide groove 3 serves to guide and limit the movement of the movable block 6. The clockwise and counterclockwise rotation of the bidirectional screw 4 drives the two threaded blocks 5 to move relative to and away from each other. A ball can be set at the bottom end of the fixed block 7 to roll in contact with the mounting base 1, thereby reducing movement friction.

[0023] Furthermore, a worm 73 is fixedly mounted on the output shaft of the servo motor 72 through a coupling, the outer surface of the worm 73 meshes with the tooth surface of the worm wheel 71, and a side plate 74 is movably inserted on the upper surface of the fixed plug block 7. The servo motor 72 drives the worm 73 to rotate clockwise and counterclockwise, and the rotation of the worm 73 drives the meshing worm wheel 71 to rotate.

[0024] Furthermore, a positioning slot 75 is provided on the upper surface of the side panel 74, and the upper surfaces of the two side panels 74 are in contact with the lower surface of the top plate 2. The lower surface of the top plate 2 is provided with symmetrically distributed limiting grooves 76, and the inner top wall of the limiting groove 76 is provided with fixed grooves 77 distributed in a linear array, and the cross-section of the limiting groove 76 is T-shaped.

The outer surface of the positioning plug plate 79 is movably plugged into the inner wall of the positioning slot 75.

[0029] Working principle: Step 1, when adjusting the side plate 74, start the servo motor 72 to drive the worm 73 to rotate clockwise, the rotation of the worm 73 drives the bidirectional screw 4 to rotate through the meshing worm wheel 71, the rotation of the bidirectional screw 4 drives the moving block 6 to move relatively through the two threaded blocks 5, thereby driving the side plate 74 to move relatively through the cooperation of the moving block 6 and the fixed plug block 7. Conversely, start the servo motor 72 to drive the worm 73 to rotate counterclockwise, the worm 73 drives the bidirectional screw 4 to rotate in the opposite direction through the meshing worm wheel 71, thereby driving the two side plates 74 to move back to back for adjustment;
