[0002] Existing enclosed sound barrier structures are typically fixed via pre-embedded foundations or welding. In road expansion or temporary construction scenarios, these structures are difficult to adjust or relocate to meet subsequent needs. Removing the sound barrier may damage the original foundation, and it is difficult to reuse the structure after dismantling, resulting in high secondary construction costs and limiting its application. Therefore, we propose an enclosed sound barrier device. Utility Model Content

[0003] The purpose of this utility model is to provide a closed sound barrier device to solve the problems mentioned in the background art. The existing closed sound barrier device structure is usually fixed by pre-embedded foundation or welding. In road expansion or temporary construction scenarios, it is difficult to adjust or relocate according to subsequent needs. If the sound barrier needs to be removed, it may damage the original foundation. Moreover, it is difficult to reuse after disassembly, resulting in high secondary construction costs and limiting its scope of application.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a closed sound barrier device, comprising: a first barrier frame, an adjustable outward expansion component provided on the side surface of the first barrier frame, a second barrier frame movably connected to the outer surface of the outward expansion component, and a positioning and anti-loosening buffer component provided inside the outward expansion component.

[0005] The external expansion component includes a connecting box, a fixed ring fixedly connected to the outer surface of the connecting box, a rotating ring movably connected inside the fixed ring, a linkage rod fixedly connected to the outer surface of the rotating ring, a first bevel gear fixedly connected to the end of the linkage rod away from the rotating ring, a second bevel gear meshing with the side surface of the first bevel gear, a threaded rod fixedly connected to the center of the second bevel gear, a push block threadedly connected to the outer surface of the threaded rod, and a guide plate slidably connected to the bottom of the push block.

[0006] The push block has a groove on its side surface, a limit block is movably connected inside the groove, a fixed plate is movably connected to the end of the limit block away from the push block, and a positioning groove is movably connected to the outer surface of the groove. The positioning groove is opened on the inner wall of the second barrier frame.

[0007] The buffer assembly includes a connecting block, which is fixedly connected to the inner surface of the limiting block, and a limiting plate is fixedly connected to the outer surface of the connecting block.

[0008] Among them, a spring column is fixedly connected to the end of the limiting plate away from the connecting block, a support plate is fixedly connected to the outer surface of the spring column, and a protective seat is fixedly connected to the side surface of the support plate.

[0009] The connecting block, spring column, and limit plate are arranged symmetrically in two groups on the left and right sides of the protective seat.

[0010] This utility model has at least the following beneficial effects:

[0011] 1. In use, this utility model, through the linkage rod and push block in the extended component, can use tools to rotate the first bevel gear according to the actual road width to limit and fix the extended first barrier frame and the extended component. The width of the first barrier frame and the extended component can be flexibly adjusted to better adapt to various road specifications. Whether it is a narrow rural road or a multi-lane highway, it can effectively cover the noise source and improve the noise reduction effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a closed sound barrier device, including: a first barrier frame 1, an expansion component 2 with adjustable width provided on the side surface of the first barrier frame 1, a second barrier frame 3 movably connected to the outer surface of the expansion component 2, and a positioning and anti-loosening buffer component 4 provided inside the expansion component 2.

[0020] In use, by using the linkage rod 24 and push block 27 in the extended component 2, the first bevel gear 25 can be rotated with tools to limit and fix the extended first barrier frame 1 and the extended component 2 according to the actual road width. The width of the first barrier frame 1 and the extended component 2 can be flexibly adjusted to better adapt to roads of various specifications. Whether it is a narrow rural road or a multi-lane highway, it can effectively cover the noise source and improve the noise reduction effect. Secondly, the operation of rotating the linkage rod 24 at the top for extension and limitation is relatively simple, which is convenient for construction personnel to install and debug on site, reducing complex installation procedures and tool requirements, and reducing installation difficulty and labor intensity.

[0021] The external expansion component 2 includes a connecting box 21. A fixing ring 22 is fixedly connected to the outer surface of the connecting box 21. A rotating ring 23 is movably connected inside the fixing ring 22. A linkage rod 24 is fixedly connected to the outer surface of the rotating ring 23. A first bevel gear 25 is fixedly connected to the end of the linkage rod 24 away from the rotating ring 23. A second bevel gear 26 meshes with the side surface of the first bevel gear 25. A threaded rod 213 is fixedly connected to the center of the second bevel gear 26. A push block 27 is threadedly connected to the outer surface of the threaded rod 213. A guide plate 28 is slidably connected to the bottom of the push block 27. A sliding groove 29 is opened on the side surface of the push block 27. A limiting block 210 is movably connected inside the sliding groove 29. A fixing plate 212 is movably connected to the end of the limiting block 210 away from the push block 27. A positioning groove 211 is movably connected to the outer surface of the sliding groove 29. The positioning groove 211 is opened on the inner wall of the second barrier frame 3.

[0022] In use, firstly, the first barrier frame 1 and the second barrier frame 3 are symmetrically pulled together via the outward expansion component 2 to create a suitable width expansion between them. Then, a five-pointed wrench is inserted into the fixed ring 22 to rotate the rotating ring 23. This causes the rotating ring 23 to drive the first bevel gear 25 to rotate via the linkage rod 24. The second bevel gear 26 is symmetrically meshed at both ends of the first bevel gear 25. When the first bevel gear 25 rotates, it converts the vertical rotational force into a horizontal rotational force through the second bevel gear 26, causing the second bevel gear 25 to rotate. The gear 26 is fixedly connected to the threaded rod 213, which pushes the push block 27 to slide on the upper surface of the guide plate 28. During the sliding process, the push block 27 will push the limiting block 210 outward through the sliding groove 29, so that the end of the limiting block 210 away from the push block 27 is limited inside the positioning groove 211. Since the connecting box 21 and the fixing plate 212 are fixedly connected, when the limiting block 210 is pushed to limit the first barrier frame 1 and the second barrier frame 3, the first barrier frame 1 and the outward expansion component 2 and the second barrier frame 3 can be well fixed.

[0023] The buffer assembly 4 includes a connecting block 41, which is fixedly connected to the inner surface of the limiting block 210. A limiting plate 42 is fixedly connected to the outer surface of the connecting block 41. A spring post 43 is fixedly connected to the end of the limiting plate 42 away from the connecting block 41. A support plate 44 is fixedly connected to the outer surface of the spring post 43. A protective seat 45 is fixedly connected to the side surface of the support plate 44.

[0024] When in use, when the limiting block 210 is pushed by the pushing block 27 against the inside of the positioning groove 211, the limiting block 210 will squeeze the spring column 43. After the limiting block 210 slides into the inside of the positioning groove 211, under the elasticity of the spring column 43, the spring column 43 will push the connecting block 41, so that the limiting block 210 is against the inside of the positioning groove 211, thereby playing a role in stabilizing the connection between the fixing plate 212 and the first barrier frame 1 and the second barrier frame 3. At the same time, due to the characteristics of the spring column 43, it can play a certain role in shock resistance during connection, greatly improving the connection stability of the device.
