By using the fixing components, it is convenient to fix the semi-circular blocks 3, so as to realize the fixing of the sound barrier body 4, and the operation is simple and convenient.

[0024] In the present utility model, the fixing component includes a cavity 14 opened on the top of the semi-circular block 3, a limiting block 12 slidably arranged in the cavity 14, and a circular column 9 arranged on the limiting block 12. An extrusion spring 13 is sleeved on the outer wall of the circular column 9 between the limiting block 12 and the cavity 14. By using the extrusion spring 13, it is convenient to extrude the limiting block 12, so as to facilitate the stable fixing of the semi-circular block 3; a circular groove 11 is opened on the top surface of the column 2, the top of the circular column 9 movably penetrates through the circular groove 11 and is fixedly connected with a circular plate 8, and a handle 7 and a fixing member are fixedly connected to the top of the circular plate 8. By using the fixing member, it is convenient to fix the circular plate 8, so as to realize the fixing of the semi-circular block 3; wherein, both the cavity 14 and the limiting block 12 are polygonal, and the limiting block 12 and the cavity 14 cooperate with each other, which is convenient for the limiting block 12 to drive the semi-circular block 3 to rotate when rotating, so as to facilitate the change of the orientation of the second installation groove 5 on the semi-circular block 3, and further facilitate the installation of the sound barrier body 4.

[0025] In the present utility model, the fixing member includes a clamping rod 6 fixedly connected to the outer wall of the circular plate 8, and a plurality of clamping grooves 10 are opened on the inner wall of the circular groove 11 to cooperate with the clamping rod 6. By the mutual cooperation of the clamping grooves 10 and the clamping rod 6, the fixing of the circular plate 8 is realized, so as to realize the fixing of the semi-circular block 3.

[0026] In the present utility model, clamping blocks 15 are symmetrically and fixedly connected to the side surface of the sound barrier body 4, and a second installation groove 5 is opened on the semi-circular block 3 to cooperate with the clamping blocks 15.

Specifically: first pull up the handle 7 to drive the circular plate 8 to move upward, and then drive the clamping rod 6 to move upward, so that the clamping rod 6 is separated from the clamping groove 10, releasing the fixation of the circular plate 8. Then rotate the handle 7 to drive the circular plate 8 to rotate, and then drive the limiting block 12 to rotate, thereby driving the semi-circular block 3 to rotate, further driving the mounting groove two 5 to rotate. When the mounting grooves two 5 on the two semi-circular blocks 3 are coplanar, release the handle 7. Under the action of the compression spring 13, the circular plate 8 enters the circular groove 11, and the clamping rod 6 enters the clamping groove 10 to achieve the fixation of the semi-circular block 3. Then, clamp the clamping blocks 15 at both ends of the sound barrier body 4 into the mounting groove two 5 to complete the installation of the sound barrier body 4.
