The outer surfaces of the two limiting blocks 33 are slidably connected to the inner surfaces of the two slots 23 in the vertical direction.

[0029] When it is necessary to assemble and use, the connecting plate 32 in the mounting plate 3 is inserted into the inside of the slide groove 21 by knocking the rubber plate 31, so that the lower surface of the mounting plate 3 contacts the buffer plate 4 and has a certain buffering effect. When the mounting plate 3 moves downward to an appropriate position, the limit block 33 enters the inside of the slot 23, and then the locking block 24 is set to facilitate the restriction and fixation of its position, and the rubber plate 31 has a protective effect on the mounting plate 3.

[0030] like Figure 3 As shown, the locking block 24 includes a plate 241, the outer surface of the plate 241 is fixedly connected with a strip block 242, the outer surface of the strip block 242 is slidably connected to the inside of the limiting groove 22, the upper surface of the plate 241 is fixedly connected with an L-shaped block 243 on one side close to the limiting groove 22, the inside of the L-shaped groove 34 is clamped with the outer surface of the L-shaped block 243, and the outer surface of the fixing bolt is connected with the horizontal inner thread of the L-shaped block 243;

The bolts and the mounting holes 3052 are provided to facilitate the installation and fixing of the mounting plate 3.

[0034] Let’s talk about the working principle of the pointed wedge type sound barrier in detail.

[0035] The connecting plate 32 in the mounting plate 3 is inserted into the interior of the slide groove 21. When the mounting plate 3 moves downward to the appropriate position, the limit block 33 enters the interior of the slot 23. Then, the bar block 242 is inserted into the interior of the limit groove 22 and slides, so that the L-shaped block 243 contacts the L-shaped slot 34 and is stuck.
