[0002] A soundproof enclosure is a device used to isolate, absorb, or reduce noise, and is widely used in industrial testing, product development, and noise control.

[0003] In the prior art, patent document CN217880834U discloses a soundproof enclosure with a double-box structure. The soundproof enclosure includes an outer box and an inner box, with the inner box placed within the outer box cavity via a mounting pad. The inner box includes an inner body and an inner door; one side of the inner door is hinged to the inner body, and the other side is locked to the inner body via an inner box locking mechanism; the inner door is equipped with a rib mechanism. The outer box includes an outer body and an outer door, with one side of the outer door hinged to the outer body, and the other side locked to the outer body via an outer box locking mechanism.

[0027] The present invention will be further described in detail below with reference to embodiments: Example

[0028] like Figure 1-5As shown, this utility model provides a double-box structure for testing soundproof enclosures, including an outer soundproof unit 1 and an inner soundproof unit 2 disposed inside the outer soundproof unit 1 for placement. The outer soundproof unit 1 includes an outer soundproof component and a push-pull component disposed inside the outer soundproof component. The inner soundproof unit 2 includes an inner soundproof component disposed on the outer surface of the outer soundproof unit 1 and a placement component disposed on the outer surface of the inner soundproof component. The outer surface of the FC soundproof panel 12 is provided with sound-absorbing cotton, and the bottom surface of the inner wall of the soundproof enclosure 11... The detachable connection includes a limiting plate 14. The push-pull assembly includes a limiting frame 13. The outer surface of the limiting frame 13 is slidably connected to the inner wall of the soundproof box 11. A soundproof sealing door 15 is fixedly connected to one side of the limiting frame 13. A support frame 16 is slidably connected to the inner wall of the soundproof sealing door 15. A fixing bolt 17 is threadedly connected to the inner wall of the support frame 16. The outer surface of the fixing bolt 17 is movably engaged with the outer surface of the soundproof sealing door 15. An L-shaped limiting plate 18 is slidably connected to the inner wall of the limiting frame 13. The inner wall of the L-shaped limiting plate 18 is threaded... The soundproof enclosure is connected by a fixing bolt 19, one end of which is threaded to a limiting block 110 that slides on the inner wall of the limiting frame 13. When using the soundproof enclosure, the soundproof sealing door 15 must first be opened. By pulling the soundproof sealing door 15, it is moved under the limiting of the limiting frame 13 and the FC soundproof panel 12. After moving to the appropriate position, the fixing bolt 17 is rotated to raise and lower the support frame 16 inside the soundproof sealing door 15, thus facilitating the adjustment of the support frame 16's position. Then, the support frame 16 is used to assist in adjusting the position of the enclosure. The soundproof and sealed door 15 is used for support, and then the inner soundproof unit 2 can be placed on the upper surface of the limiting frame 13. The position of the L-shaped limiting plate 18 is adjusted by rotating the fixing bolt 19 in conjunction with the limiting block 110, thereby assisting in limiting and fixing the inner soundproof unit 2. Then, the product that needs to be tested for soundproofing is placed in the inner soundproof unit 2, and the inner soundproof unit 2 is pushed into the interior of the soundproof box 11. Utilizing the soundproofing effect of the FC soundproofing board 12, the product can be tested for soundproofing a second time in conjunction with the inner soundproof unit 2. Example

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the inner sound insulation component includes a second sound insulation box 21, which is movably engaged with the outer surface of the L-shaped limiting plate 18. The second sound insulation box 21 is placed on the upper surface of the limiting frame 13. A sealing door 22 is rotatably connected to the outer surface of the second sound insulation box 21. A sound-absorbing plate 23 is fixedly connected to the outer surface of the sealing door 22. An FC sound insulation plate 24 is fixedly connected to the inner wall of the second sound insulation box 21. The placement component includes a placement rack 25, the bottom surface of which is fixedly connected to the inner wall surface of the second sound insulation box 21. When it is necessary to place the product, the sealing door 22 can be opened, the product can be placed on the upper surface of the placement rack 25, and the sealing door 22 can be closed. The inner sound insulation unit 2 is used to test the sound insulation of the product.

[0030] The working principle of the test soundproof box with this double-box structure will be explained in detail below.

[0031] like Figure 1-5 As shown, when using the soundproof enclosure, the soundproof sealing door 15 needs to be opened first. By pulling the soundproof sealing door 15, it can be moved under the limitation of the limiting frame 13 and the FC soundproof panel 12. After it moves to the appropriate position, the support frame 16 can be raised and lowered inside the soundproof sealing door 15 by rotating the fixing bolt 17, so as to facilitate the adjustment of the position of the support frame 16. Then, with the help of the support frame 16, the soundproof sealing door 15 can be supported. Then, the inner soundproof unit 2 can be placed on the upper surface of the limiting frame 13. The fixing bolt 19 can be rotated in conjunction with the limiting block 110 to adjust. The L-shaped limiting plate 18 is positioned to assist in limiting and fixing the inner sound insulation unit 2. Then, the product that needs to be tested for sound insulation is placed in the inner sound insulation unit 2. When the product needs to be placed, the sealing door 22 can be opened, and the product can be placed on the upper surface of the placement rack 25. Then, the sealing door 22 is closed. The inner sound insulation unit 2 is used to test the sound insulation of the product. Then, the inner sound insulation unit 2 is pushed into the sound insulation box 11. The sound insulation effect of the FC sound insulation board 12, together with the inner sound insulation unit 2, can be used to test the sound insulation of the product a second time.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
