Sealed, soundproof testing chambers serve as an important acoustic testing environment, effectively isolating external noise interference and providing the necessary conditions for accurate acoustic testing.

[0003] However, existing sealed test soundproof rooms have some limitations in practical applications. On the one hand, with the development of technology and the upgrading of products, testing needs are constantly changing. Sometimes it is necessary to adjust the internal space of the soundproof room to accommodate test objects of different sizes and types, but the traditional soundproof room structure is fixed and difficult to expand and modify flexibly. On the other hand, when multiple test items need to be carried out simultaneously or new test equipment needs to be added, the existing soundproof room often cannot meet the space requirements, and building a new soundproof room will consume a lot of time and cost. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0022] Please see Figures 1-5 In this utility model, an expandable sealed test soundproof chamber includes two soundproof chamber main frames 1. The soundproof chamber main frames 1 have evenly distributed connecting slots 101. Evenly distributed connecting columns 2 are arranged between the two soundproof chamber main frames 1. The two ends of the connecting columns 2 are respectively located inside the two connecting slots 101. Evenly distributed connecting rods 3 are threaded to the outer side of the soundproof chamber main frames 1. The connecting rods 3 penetrate the soundproof chamber main frames 1 and are threaded into the connecting columns 2. Evenly distributed connecting columns 2 are provided on the soundproof chamber main frames 1. The two soundproof rooms have evenly distributed splicing grooves 102. On one side of the two main frames 1 of the soundproof room, there are evenly distributed soundproof panels 4. The left and right sides of the soundproof panels 4 are located inside the two splicing grooves 102 respectively. Two through grooves 103 are opened on the inner wall of the splicing grooves 102 on the front and back. The soundproof panels 5 are slidably installed on the inner wall of the main frame 1 of the soundproof room. The front and rear sides of the soundproof panels 5 extend through and to the outside of the main frame 1 of the soundproof room. An expansion box 6 is installed on the soundproof panel 4 on the front side. A sealing door 7 is connected to the expansion box 6.

[0023] The two ends of the connecting column 2 are respectively located at the center of the connecting groove 101 of the two main frames of the soundproof room 1. The left and right sides of the top and bottom soundproof panels 4 are respectively located at the center of the splicing groove 102 of the two main frames of the soundproof room 1. The left and right sides of the front and back soundproof panels 4 are respectively in contact with the soundproof panels 5 inside the two main frames of the soundproof room 1. The soundproof panels 5 and the inner wall of the through groove 103 are slidably sealed.

[0024] When assembling a soundproof room, first, two sets of soundproof room main frames 1 can be erected vertically, and multiple soundproof room main frames 1 can be placed horizontally. Then, multiple connecting posts 2 can be inserted into the connecting grooves 101 of the soundproof room main frame 1, so that the threaded holes on the connecting posts 2 correspond to the threaded holes on the outside of the soundproof room main frame 1. After the connection is completed, the connecting rods 3 can be screwed in to achieve a stable connection of the soundproof room main frame 1.

[0025] Next, the user slides the soundproof panel 4 into the splicing groove 102. The length of the corresponding splicing groove 102 in the main frame 1 of two adjacent soundproof rooms is greater than the length of the soundproof panel 4. Figure 1 As shown, if this specification of soundproof room is installed, after the soundproof panel 4 is inserted, the soundproof panel 5 can be slid into the through groove 103, so that the soundproof panel 5 can block the side of the main frame 1 of the soundproof room, thereby forming a soundproof space. The expansion box 6 and the sealing door 7 can be installed later for easy access.

[0026] If expansion of space is required, such as Figure 2 As shown, the user first needs to remove and slide out the second soundproof panel 5 from the main frame 1 of the left-side soundproof room. Then, the user places a new main frame 1 of the soundproof room on the left side of the soundproof room and connects it to the connecting column 2. The user then inserts the first soundproof panel 4 from the left side of the main frame 1 of the soundproof room and connects them with bolts. Then, the user inserts the second soundproof panel 5 into the leftmost main frame 1 of the soundproof room to form a new soundproof room. Finally, the user needs to insert the cut short soundproof panels into the front and back of the main frame 1 of the soundproof room in the middle position to further seal it. At this time, the space can be expanded to meet the needs of equipment testing. Similarly, if further expansion is needed, the above steps should be repeated.

[0027] In this invention, the main frame 1 of the soundproof room is assembled with the connecting columns 2 and connecting rods 3 to achieve stable assembly, ensuring structural stability and durability. The sound insulation panel 1 4 and the sound insulation panel 2 5 are slidably installed to form a seamless soundproof space, effectively isolating external noise and providing a precise environment for acoustic testing. By disassembling the sound insulation panel 2 5 and adding a new main frame 1 of the soundproof room, flexible expansion can be achieved to adapt to different scale testing needs, avoiding reconstruction costs. The modular design facilitates disassembly and assembly, meeting diverse scenario needs and is suitable for industries such as electronics, machinery, automobiles, and aerospace.

[0028] Please see Figure 1 and 2 Among them, a handle 701 is fixedly installed on the front of the sealed door 7, and the handle 701 has evenly distributed anti-slip texture.

[0029] In this utility model, when a user needs to use the sealed door 7, the handle 701 can provide a good point of leverage, and the anti-slip texture can increase friction to prevent the hand from slipping.

[0030] Please see Figure 5 Among them: the interior of the two soundproof room main frame 1 is equipped with evenly distributed sealing strips 8, and the connection gaps between the connecting column 2, sound insulation board 1 4, sound insulation board 2 5 and the soundproof room main frame 1 are all connected by sealing strips 8.

[0031] In this invention, the sealing strip 8 can further improve the overall sound insulation effect of the soundproof room, and the sealing strip 8 is easy to install and remove, making it convenient for subsequent expansion.

[0032] Please see Figure 1 and 2 Among them, a support plate 9 is set between the two main frames 1 of the soundproof room, and the support plate 9 is in contact with the bottom sound insulation plate 4.

[0033] In this invention, the support plate 9 can support the bottom sound insulation plate 4, providing stable support when the equipment is placed on top of the sound insulation plate 4.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
