It also includes a main connection component 3, and the main connection component 3 includes: a sleeve 31, a perforated connecting ear 311, a C-shaped connecting frame 32, and a connecting bar 321.

[0036] Further, as shown by Figure 1 and Figure 2 In this embodiment, the sleeve 31 is sleeved on the main column 1. Two groups of perforated connecting ears 311 are symmetrically fixed on the outer wall of the sleeve 31, and two perforated connecting ears 311 in the same group are symmetrically distributed. The main noise reduction barrier 2 is fixedly connected to the C-shaped connecting frame 32, and there is an installation hole 322 corresponding to the fixing hole 21 on the C-shaped connecting frame 32. The connecting bar 321 is fixed on the C-shaped connecting frame 32 and is rotatably connected between two perforated connecting ears 311 in the same group by a connecting column 33. After adopting the above scheme, during use, first fix the main column 1 to the ground by conventional means. The same main noise reduction barrier 2 is installed using two adjacent main columns 1 and main connection components 3. Use bolts to fix the main noise reduction barrier 2 and the C-shaped connecting frame 32. The main connection component 3 can rotate relative to the main column 1, and the main noise reduction barrier 2 can rotate through the connecting column 33. The main noise reduction barrier 2 can be adjusted to an appropriate angle according to actual needs to meet different corner connection requirements, which is more convenient to use and greatly reduces costs.

[0037] Preferably, as shown by Figure 1 and Figure 2 In this embodiment, there is a reserved threaded hole 312 on the sleeve 31. When it is not necessary to rotate the sleeve 31, bolts can be screwed into the reserved threaded hole 312 to make the bolts abut against the main column 1, avoiding accidental self-rotation of the sleeve 31 and ensuring the stability of the sleeve 31.

[0038] Preferably, as shown by Figure 1 and Figure 2 In this embodiment, the end of the main noise reduction barrier 2 is embedded in the inner side of the C-shaped connecting frame 32, and the outer wall of the main noise reduction barrier 2 abuts against the inner wall of the C-shaped connecting frame 32, which is convenient for connection, has high stability, and uses bolts to fix the main noise reduction barrier 2 and the C-shaped connecting frame 32.

[0039] Preferably, as shown by Figure 1 and Figure 2 In this embodiment, the length of the connecting bar 321 is equal to the distance between two perforated connecting ears 311 in the same group, improving the installation stability of the C-shaped connecting frame 32 and avoiding longitudinal jitter of the C-shaped connecting frame 32.

[0040] Preferably, as shown by Figure 1 andFigure 2 As shown, in this embodiment, the outer wall of the main column 1 abuts against the inner wall of the sleeve 31, which improves the connection stability between the sleeve 31 and the main column 1 and prevents the sleeve 31 from shaking.

[0041] Preferably, Figure 1 As shown, in this embodiment, it further includes: a secondary column 4, a secondary connection assembly 6, and a secondary noise barrier 5. The secondary column 4 is fixed to the top end of the main column 1, the secondary connection assembly 6 is installed on the secondary column 4, and the secondary noise barrier 5 is fixed to the secondary connection assembly 6. After adopting the above solution, when it is necessary to expand the noise reduction range, the secondary column 4 can be first fixed to the top end of the main column 1, and then the secondary noise barrier 5 can be fixed to the secondary column 4 by using the secondary connection assembly 6 to increase the overall height.

[0042] It should be noted that in this utility model, the structural composition of the secondary connection assembly 6 is completely the same as that of the main connection assembly 3, and they have the same installation method. The secondary connection assembly 6 and the main connection assembly 3 may only differ in size. On the premise that the structural composition and usage method of the main connection assembly 3 have been fully described, the secondary connection assembly 6 will not be elaborated too much in this article.

[0043] Optionally, Figure 1 and Figure 3 As shown, in this embodiment, it further includes: a threaded column 41. There is an internal thread groove 12 at the top end of the main column 1. The threaded column 41 is fixed to the bottom end of the secondary column 4 and is screwed into the internal thread groove 12 by a threaded engagement method. After adopting the above solution, this utility model uses a threaded engagement method to fixedly install the secondary column 4, which is convenient and stable for installation and is also easy to disassemble.

[0044] Optionally, Figure 1 and Figure 4 As shown, in this embodiment, it further includes: a splicing plug 51. There is a splicing slot 22 at the top end of the main noise barrier 2. The splicing plug 51 is fixed to the bottom end of the secondary noise barrier 5 and is embedded in the splicing slot 22. After adopting the above solution, when the secondary noise barrier 5 is fixed to the secondary connection assembly 6, the splicing plug 51 is embedded in the splicing slot 22 to splice the secondary noise barrier 5 and the main noise barrier 2, further improving the stability between the secondary noise barrier 5 and the main noise barrier 2.

[0045] The components not described in detail in this article are prior art.

[0046] Working principle and usage process of the present utility model: For the noise reduction barrier of the present utility model, during use, first fix the main column 1 to the ground by conventional means.

The main connection component 3 can rotate relative to the main column 1, and the main noise reduction barrier 2 can rotate through the connection column 33. The main noise reduction barrier 2 can be adjusted to an appropriate angle according to actual needs to meet different corner connection requirements, which is more convenient to use and greatly reduces costs;

[0047] When the sleeve 31 does not need to be rotated, a bolt can be screwed into the reserved threaded hole 312 to make the bolt abut against the main column 1, avoiding accidental self-rotation of the sleeve 31 and ensuring the stability of the sleeve 31;

[0048] When it is necessary to expand the noise reduction range, the auxiliary column 4 can be first fixed to the top of the main column 1, and then the auxiliary noise reduction barrier 5 is fixed to the auxiliary column 4 using the auxiliary connection component 6 to increase the overall height.
