[0002] A noise reduction device is a device or technology used to reduce noise levels by eliminating the source of the sound or preventing it from traveling.

[0003] Common noise reduction devices used in workshops usually use soundproof enclosures to separate the noise source from the surrounding area, which can achieve the noise reduction effect. However, they lack an adjustment mechanism and cannot flexibly adjust the size of the soundproof enclosure. As a result, the size of the soundproof enclosure and the noise source may not match, affecting the normal use of the soundproof enclosure and reducing its practicality.

[0004] Therefore, in view of the fact that the above-mentioned workshop noise reduction device lacks an adjustment mechanism and cannot flexibly adjust the size of the sound insulation cover, a flexibly adjustable zipper production workshop noise reduction device can be designed. By pushing the extension cover, the connecting rod on the rear side can drive the U-shaped connecting frame to move in the connecting groove. When the U-shaped connecting frame moves, the four self-locking pull rods on the rear side will be stretched, so that the extension cover can be moved out from the inside of the connecting groove, so as to achieve the purpose of flexibly adjusting the effective range of the sound insulation cover, thereby improving practicality.

By pushing the extension cover 12, the connecting rod 11 on the rear side can drive the U-shaped connecting frame 9 to move in the connecting groove 3. When the U-shaped connecting frame 9 moves, the four self-locking pull rods 8 on the rear side will be stretched, so that the extension cover 12 can be moved out from the inside of the connecting groove 3, so as to achieve the purpose of flexibly adjusting the effective range of the sound insulation cover 1, thereby avoiding the situation where the sound insulation cover 1 does not match the noise source. In addition, by arranging the pulley 18 at the bottom of the extension cover 12, it is easier to move the extension cover 12, thereby improving the practicality of the extension cover 12.

[0025] Please refer to 1- Figure 6 In this embodiment, a cooling fan 2 is installed at the center of the rear side of the soundproof enclosure 1. The front end of the cooling fan 2 passes through the soundproof enclosure 1 and is located at the rear side of the interior of the soundproof enclosure 1. By arranging the cooling fan 2 at the rear side of the soundproof enclosure 1, the interior of the soundproof enclosure 1 and the extension cover 12 can be cooled to avoid excessive internal temperature due to the sealed environment. Four T-shaped slides 4 are symmetrically opened on the left and right sides of the interior of the soundproof enclosure 1. T-shaped sliders 5 are installed inside the T-shaped slides 4. The outer sides of the T-shaped sliders 5 are symmetrically connected to two first sound insulation back panels. 6. By inserting the T-shaped slider 5 into the interior of the T-shaped slide groove 4, the installation and disassembly of the first sound insulation back panel 6 are more convenient, and the efficiency of disassembly is improved. A first sound absorbing panel 7 is provided on the outside of the first sound insulation back panel 6. The first sound insulation back panel 6 and the first sound absorbing panel 7 are connected by an adhesive. The first sound insulation back panel 6 can not only be used to connect the first sound absorbing panel 7, but also improve the overall strength of the first sound absorbing panel 7. The first sound absorbing panel 7 can block and absorb the noise inside the soundproof cover 1 to achieve a noise reduction effect.

[0026] Please refer to 1- Figure 6In this embodiment, the interior of the extension cover 12 is symmetrically provided with mounting grooves 13 on both sides. Four telescopic rods 14 are symmetrically provided at the upper and lower ends of the rear sides of the two mounting grooves 13. The other ends of the telescopic rods 14 are connected to a fixing plate 15. Through the telescopic operation of the four telescopic rods 14, the positions of the second sound insulation back plate 16 and the second sound absorbing plate 17 on the front side of the fixing plate 15 can be controlled, thereby achieving the effect of flexible adjustment according to the extension range of the extension cover 12. The front side of the fixing plate 15 is connected to the second sound insulation back plate 16, and the outer side of the second sound insulation back plate 16 is provided with a second sound absorbing plate 17. The sound back panel 16 and the second sound absorbing panel 17 are connected by an adhesive. The second sound insulation back panel 16 can be used to improve the strength of the overall connection structure of the second sound absorbing panel 17, and the second sound absorbing panel 17 can be used to reduce the noise source in the extension cover 12. A sealing door 19 is installed on the front side of the extension cover 12. The sealing door 19 is made of steel plate, and sound-absorbing cotton is pasted on the inside of the sealing door 19. The sealing door 19 can be used to seal the front side of the extension cover 12, and by arranging sound-absorbing cotton on the inside of the sealing door 19, the spread of noise can be further avoided and the noise reduction effect can be improved.

[0027] During operation, the interior of the soundproof enclosure 1 and the extension cover 12 can be cooled by the cooling fan 2 on the rear side of the soundproof enclosure 1 to avoid excessive internal temperature due to the sealed environment, and by inserting the T-shaped slider 5 into the interior of the T-shaped slide 4, the installation and removal of the first soundproof backboard 6 can be made more convenient, thereby improving the efficiency of assembly and removal. The first soundproof backboard 6 can not only be used to connect the first sound-absorbing board 7, but also improve the overall strength of the first sound-absorbing board 7. The first sound-absorbing board 7 can block and absorb the noise inside the soundproof enclosure 1 to achieve the effect of noise reduction, and when When the sound insulation cover 1 cannot completely cover the noise source, the extension cover 12 can be pushed to cause the connecting rod 11 on the rear side to drive the U-shaped connecting frame 9 to move in the connecting groove 3. When the U-shaped connecting frame 9 moves, the four self-locking pull rods 8 on the rear side will be stretched, so that the extension cover 12 can be moved out from the inside of the connecting groove 3, so as to achieve the purpose of flexibly adjusting the effective range of the sound insulation cover 1, thereby avoiding the situation where the sound insulation cover 1 does not match the noise source, and by providing a pulley 18 at the bottom of the extension cover 12, it can be more convenient to move the extension cover 12, thereby improving the practicality of the extension cover 12.

[0028] Through the above steps, by providing the extension cover 12, the coverage range of the sound insulation enclosure 1 can be flexibly adjusted, thereby solving the problem that the size of the common workshop noise reduction device cannot be flexibly adjusted due to the lack of an adjustment mechanism, which easily leads to a mismatch between the size of the sound insulation enclosure 1 and the noise source, affecting the normal use of the sound insulation enclosure 1 and reducing the practicality of the sound insulation enclosure 1.
