They are mostly used in roads, and in buildings, they are also used to block some minor noise in workshops and offices.

[0003] After searching, the patent number CN211171684U is named as a utility model of a noise barrier with adjustable angle, including a base. Through research and analysis, it is found that although the noise barrier has the advantages of achieving adjustable angle and good stability, it still has the following disadvantages to a certain extent;

The first sound insulation barrier body 2 can guide the moving range by sliding along the track of the limiting slide groove 14 through the limiting slide plate 15 at the top. The user pulls the pull ring plate 18 to generate tension on the reset spring 17 to make the plug shaft 19 move vertically away from the second sound insulation screen The surface of the barrier body 3 is pulled laterally to move the second sound barrier body 3 laterally in the inner cavity of the first sound barrier body 2, which can be adjusted according to the use length of the sound barrier. The pull ring plate 18 is loosened, and the return spring 17 generates elastic resistance to restore the plug shaft 19 to its original position and plug it into the inner cavity of the assembly groove 20 at different positions to tightly contact the second sound barrier body 3 and the first sound barrier body 2. The positioning, locking and fixing of the second sound barrier body 3 and the first sound barrier body 2 are effectively increased. The support area of ​​the sound barrier is effectively increased. The rotating bolt 16 is threadedly connected away from the slide rail 5, so that the sliding seat 12 is away from the inner cavity of the slide rail 5, and the limiting slide plate 15 is separated from the inner cavity of the limiting slide groove 14. The sound barrier can be disassembled individually to improve utilization.
