Both sides of the drive box 6 are fixedly connected with a fixing cylinder 16. The outer surface of the drive box 6 is installed with a motor 8. The output end of the motor 8 is fixedly connected with a rotating shaft 9. The other end of the rotating shaft 9 extends to the interior of the drive box 6 and is fixedly connected with a first bevel gear 10. Both sides of the first bevel gear 10 are meshed with a second bevel gear 11. The interior of the second bevel gear 11 is fixedly connected with an externally threaded rod 12. The other end of the externally threaded rod 12 extends to the interior of the fixing cylinder 16 and is movably connected with an internally threaded rod 13 through a limiting assembly.

[0034] By adopting the above technical solution, the device can quickly fix the installation plate 1 and the sound insulation board 2 through the locking mechanism, thereby greatly facilitating the operator to install and disassemble the sound insulation board 2, thereby greatly improving the practicality of the device.

[0035] In the embodiments of the present application, Figure 5 As shown, the limiting assembly includes limiting grooves 14 opened on both sides of the inner wall of the fixing cylinder 16 , and the limiting grooves 14 are internally movably connected to the limiting blocks 15 , and the other end of the limiting blocks 15 is fixedly connected to the internal threaded rod 13 .

[0036] By adopting the above technical solution and utilizing the limiting function of the limiting component, the stability of the device is enhanced.

[0037] In the embodiments of the present application, Figure 1As shown, a plurality of sound-absorbing grooves 17 are formed on the outer surface of the sound-absorbing board 3 , and sound-absorbing cotton is arranged inside the sound-absorbing grooves 17 .

When the first bevel gear 10 rotates, it drives the second bevel gears 11 on the left and right sides to rotate by meshing. When the second bevel gear 11 rotates, it drives the external threaded rods 12 on both sides to rotate respectively. Since the threads of the external threaded rods 12 on both sides are opposite, the external threaded rods 12 on both sides will respectively drive the internal threaded rods on both sides under the limiting action of the limit groove 14 and the limit block 15. The rod 13 is inserted into the positioning plates 7 on both sides, so that the sound insulation board 2 can be quickly fixed and installed. Similarly, the operator can quickly remove the sound insulation board 2 from the mounting plate 1, which greatly facilitates the operator to install and remove the sound insulation board 2, thereby greatly improving the practicality of the device. When reducing noise, the noise can be preliminarily absorbed by the sound-absorbing cotton inside the sound-absorbing board 3, thereby effectively reducing the propagation energy of the noise, and a sound-absorbing groove 17 is provided on the outside of the sound-absorbing board 3. When the noise enters the sound-absorbing board 3 through the sound-absorbing groove 17, the contact area between the noise and the sound-absorbing cotton can be increased, thereby greatly improving the noise absorption effect of the sound-absorbing cotton. Finally, the noise is further soundproofed by the sound insulation board 2, thereby greatly improving the noise reduction effect of the device.
