One end of the plug rod 19 is plugged into the inside of the slot 20. By placing multiple barrier panels 4 on the inner side of the first bracket 2 and the second bracket 3, the barrier panels 4 can be assembled into barrier assemblies of different sizes and heights according to the size of the construction site by using the plug rod 19 and the slot 20. The surrounding residents and buildings are protected from noise interference. The push rod 7 is driven downward by pulling the circular plate 8, so that the transmission rod 9 pulls the connecting plate 10 to drive the moving plate 11 to move in the direction of the push rod 7, and at the same time drives the card block 12 to move together. After the second shell 6 is aligned with the first shell 5, the rebound force of the spring 16 is used to push the moving plate 11 to drive the card block 12 to be inserted into the inside of the card slot 13 to fix the second shell 6, thereby realizing quick installation and fixation of the second bracket 3. The above structure also facilitates the disassembly of the second bracket 3 and the barrier panel 4, and the operation is simple and convenient, thereby improving the operating efficiency of the operator.

[0023] Reference Figure 3 As shown, in this embodiment: a fixing rod 14 is fixed inside the first shell 5, a through hole 15 is opened on the surface of the movable plate 11, and the inside of the through hole 15 is slidably connected to the fixing rod 14. By setting the structure of the fixing rod 14 and the through hole 15, the movement trajectory of the movable plate 11 can be restricted to avoid tilting.

[0024] Reference Figure 3 As shown, in this embodiment: a through groove 17 is provided at the bottom of the first shell 5, and the interior of the through groove 17 is slidably connected to the push rod 7. By providing the through groove 17, the moving trajectory of the push rod 7 can be restricted to ensure the stability of the push rod 7 when moving.

[0025] Reference Figure 4 As shown, in this embodiment: a guide groove 18 is opened on the surface of the connecting plate 10, and the inner wall of the guide groove 18 is slidably connected to the surface of the transmission rod 9. By providing the guide groove 18, it is possible to avoid the transmission rod 9 from getting stuck when sliding inside the connecting plate 10.

[0026] Reference Figure 5 As shown, in this embodiment: a silencer plate 21 is installed inside the barrier plate 4, a silencer channel 22 is opened on the surface of the silencer plate 21, a sound-absorbing cotton 23 is arranged inside the barrier plate 4 at the rear end of the silencer plate 21, and a cover plate 24 is installed at the rear end of the barrier plate 4. By arranging the silencer plate 21 and the silencer channel 22, after the sound wave enters the barrier plate 4, it can enter the silencer channel 22, so that the sound wave can be circled in the silencer channel 22 and propagated to the sound receiving point, but the intensity of the circling sound wave will be significantly weakened, and the sound-absorbing cotton 23 can be used to absorb the noise, so as to effectively block and absorb the sound wave, and significantly reduce the propagation and influence of the noise.

[0027] Working principle: the user places multiple barrier panels 4 on the inner side of the first bracket 2 and the second bracket 3, and uses the insertion rod 19 and the slot 20 to assemble the barrier panels 4 into barrier assemblies of different sizes and heights according to the size of the construction site, so as to protect the surrounding residents and buildings from noise interference. The user also drives the push rod 7 to move downward by pulling the circular plate 8, so that the transmission rod 9 pulls the connecting plate 10 to drive the movable plate 11 to move in the direction of the push rod 7, and drives the card block 12 to move together. After aligning the second shell 6 with the first shell 5, the rebound force of the spring 16 is used to push the movable plate 11 to drive the card block 12 to be inserted into the inside of the card slot 13, so as to fix the second shell 6, thereby realizing quick installation and fixation of the second bracket 3. The above structure also facilitates the second bracket 3 and the barrier panel. The barrier plate 4 can be disassembled, and the operation is simple and convenient, which improves the operating efficiency of the operator. By setting the structure of the fixing rod 14 and the through hole 15, the movement trajectory of the movable plate 11 can be limited to avoid tilting. By setting the through groove 17, the movement trajectory of the push rod 7 can be limited to ensure the stability of the push rod 7 when moving. By setting the guide groove 18, the transmission rod 9 can be prevented from getting stuck when sliding inside the connecting plate 10. By setting the silencer plate 21 and the silencer channel 22, the sound waves can enter the barrier plate 4 and enter the silencer channel 22, so that the sound waves can be circumvented and propagated to the sound receiving point in the silencer channel 22, but the intensity of the circumvented sound waves will be significantly weakened, and the sound-absorbing cotton 23 can be used to absorb the noise, so as to effectively block and absorb the sound waves and significantly reduce the propagation and impact of the noise.
