Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to a fully enclosed sound barrier with good sound insulation performance. Background Art

[0002] At present, the existing sound barrier products in China are mainly divided into two types: outdoor and indoor. The sound barrier is generally a vertical sound barrier, which is installed on the upper end of the anti-collision platform on both sides of the road. In actual use, it is limited by various factors such as installation technology and on-site conditions. No matter what connection method is used between the vertical sound barrier and the anti-collision platform, there will be a certain gap between the upper end of the anti-collision platform and the vertical sound barrier, resulting in some holes. The disadvantage of this sound barrier is that the holes at the connection between the concrete anti-collision platform and the vertical sound barrier leak sound, and the noise reduction effect is poor.

[0003] After searching, Chinese Patent Publication (Announcement) No. CN2711226Y discloses a sound barrier. This patent uses a lower vertical sound barrier to avoid gaps, thereby solving the problem of sound leakage when the sound barrier is used. However, the existing sound barriers usually need to be connected to a crash barrier. During use, the sound barrier is exposed to wind and rain, and a large amount of dust will accumulate on its surface, affecting its appearance. After being connected to the crash barrier, it is difficult to quickly disassemble and maintain it when maintenance is needed. Therefore, it is necessary to design a fully enclosed sound barrier with good sound insulation performance. Utility Model Content

[0027] During specific use, the bidirectional screw 9 can perform threaded motion with the clamping plate 11 when rotating, thereby driving the clamping plate 11 to slide in the fixing groove 8, and the blocking plate 10 can limit the movement distance of the clamping plate 11.

[0028] In this embodiment, a limiting groove 12 is provided on the inner top wall of the base 2 , and the limiting groove 12 is slidably connected to the clamping plate 11 .

[0029] During specific use, the clamping plate 11 can slide with the limiting groove 12 when sliding, and the limiting groove 12 limits the clamping plate 11 so that the clamping plate 11 can only slide.
