However, existing soundproof enclosures for testing suffer from the following problems: 1) The enclosures are bulky, causing inconvenience for users during testing, movement, or placement; 2) The overly complex structure leads to high overall design and manufacturing costs, increasing unnecessary financial investment for consumers; 3) The complex structure makes overall installation difficult, requiring professional assembly, further increasing usage costs and extending waiting time for professionals; 4) Existing structures have poor sound insulation, preventing the tested items from meeting testing requirements. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0003] To address the problems of poor sound insulation, excessive size, complex structure, and difficult installation of existing soundproof boxes, this utility model provides a test soundproof box.

[0004] This utility model is achieved through the following technical solution: a soundproof test box, comprising a box body, a box cover, a sealing component, a drive assembly, a sound insulation layer, and an electrical wire entry / exit module; wherein: The enclosure contains a cavity, and a sound insulation layer is provided along the inner wall of the cavity. The top of the enclosure has an opening communicating with the cavity, and a suspended platform extending horizontally outwards. Above the opening and at the two sides of the top surface of the enclosure, front and rear slide rails extending towards the suspended platform are respectively provided. A lid is movably mounted on the opening, and both sides of the lid are connected to translation sliders limited on the front and rear slide rails. A driving assembly is provided on the suspended platform, and the driving assembly is connected to the lid, causing the lid to move along the front and rear slide rails under the action of the driving assembly. The slide rails reciprocate, and the top surface of the enclosure is provided with a sealing element that fits over the enclosure opening. The sealing element is sealed to the enclosure lid so that the enclosure opening is completely sealed and closed by the enclosure lid. The enclosure is provided with an electrical wire entry and exit module so that the enclosure opening can be completely sealed and closed by the enclosure lid through the sealing element. In addition, the sound insulation layer inside the enclosure provides the entire enclosure with good sound insulation effect, ensuring the accuracy of audio testing. The drive component drives the enclosure lid to slide open or close along the front and rear slide rails. This simplifies the enclosure structure, reduces the size of the enclosure, and also reduces the difficulty of enclosure installation.

[0005] Furthermore, the front and rear slide rails on both sides of the top of the box are set along the top of the box to the suspended platform. The length of the slide rails is adapted to the length of the box and the suspended platform. An L-shaped connecting frame is provided on the top of the translation slider on the front and rear slide rails. The horizontal side of the L-shaped connecting frame is connected to the translation slider, and the vertical side is connected to the side of the box cover on the same side, so that the box cover can slide back and forth along the front and rear slide rails, thereby realizing the opening and closing of the box opening.

[0006] Furthermore, the drive assembly includes front and rear telescopic rods respectively disposed on both sides of the box cover and located above the front and rear slide rails. One end of each telescopic rod is fixed to the suspended platform via a first connector, and the other end extends beyond the L-shaped connecting frame and is connected to the corresponding end of the box cover via a second connector. The first connector consists of a horizontal plate, a vertical plate, and an inclined plate connecting the two.

The fine-tuning component includes a seated bearing located at the right end of the power telescopic rod, and a horizontal lead screw whose left end is connected to the seated bearing and whose right end is connected to a screw hole on the horizontal vertical plate. The right end of the horizontal lead screw passes through the screw hole and is connected to an adjusting nut, so that rotating the adjusting nut can extend or retract the horizontal lead screw. By fine-tuning the right end of the power telescopic rod, the cover can be closed and then moved back and forth slightly along the horizontal lead screw, ultimately fitting tightly with the sealing member.

[0008] Furthermore, the sealing component includes: an upwardly protruding right vertical baffle strip along the right edge of the box opening; an inclined sealing strip with a gradually decreasing height from right to left on the top surface along the front and rear edges of the box opening; and an upwardly protruding horizontal sealing strip along the left edge of the box opening. The right end of the inclined sealing strip connects to the right vertical baffle strip, and the height of the right end of the inclined sealing strip is lower than the height of the right vertical baffle strip. The left end of the inclined sealing strip connects to the horizontal sealing strip. Correspondingly, the bottom surface of the box cover is set as an inclined surface that mates with the top surface of the inclined sealing strip of the sealing component, so that after the box cover is closed, the inclined bottom surface and the top surface of the inclined sealing strip seal together. The right end of the box cover seals with the upper part of the right vertical baffle strip, and the left edge of the bottom surface of the box cover seals with the top surface of the horizontal sealing strip, thereby achieving a complete seal between the box cover and the box opening.

[0009] Furthermore, the bottom edge of the lid, the inner side of the right vertical baffle, the upper surface of the inclined sealing strip, and the upper surface of the horizontal sealing strip are all provided with grooves for filling with lubricant, so as to ensure the airtightness between the lid and the sealing component through the lubricant in the grooves, thereby improving the sound insulation effect of the box.

[0010] Furthermore, the sound insulation layer is attached to the inner wall of the cavity, including the side walls and bottom plate. The sound insulation layer includes an outermost sound-absorbing board, a middle layer of sound-absorbing cotton connected to the sound-absorbing board, and an inner layer of foam cotton connected to the sound-absorbing cotton, so as to improve the sound insulation effect of the enclosure and thus ensure the accuracy of audio testing.

[0011] Furthermore, the lid is provided with a lid sound insulation layer. The shape of the lid sound insulation layer is adapted to the shape of the lid. The structure of the lid sound insulation layer is the same as the layered structure of the box body sound insulation layer, namely, the outermost layer is a sound-absorbing board, the middle layer is a sound-absorbing cotton connected to the sound-absorbing board, and the inner layer is a foam cotton connected to the sound-absorbing cotton.

[0012] Furthermore, a through hole is provided on the lower side wall of the enclosure, and an electrical wire inlet / outlet module is provided in the through hole.
