Through holes 104 are provided at the four corners of the two ceiling and floor panels 100. One end of the threaded rod 103 passing through the lower ceiling and floor panel 100 is threadedly connected to a bolt 105 on the outer side, and one end of the threaded rod 103 passing through the upper ceiling and floor panel 100 is threadedly connected to a nut 106 on the outer side. A slot 107 is provided at the inclined end of each wall panel 101, and a block 108 matching the slot 107 is provided on the side of the connecting column 102 close to the inclined end of the wall panel 101.

[0032] In this embodiment, two ceiling panels 100 and four wall panels 101 can be quickly assembled into a complete inflatable cabinet test room by connecting the connecting columns 102;

[0033] When assembling the inflatable cabinet test room: first, place any floor panel 100 on the ground to prevent gaps between the wall panel 101 and the ground, which would affect the test results. Then, insert the threaded rods 103 on each connecting column 102 into the corresponding through holes 104. The staff can then Figure 2-Figure 3 The notch of the ceiling floor 100 is inserted into the notch of the ceiling floor 100, and the bolts 105 are tightened to fix the ceiling floor 100 on the lower side with each connecting column 102. Then, the four wall panels 101 are respectively inserted between the adjacent connecting columns 102. In this process, the clamping block 108 is inserted into the clamping groove 107, so that the wall panels 101 and the connecting columns 102 are fixed together. Finally, another ceiling floor 100 is placed on the upper end of each wall panel 101, and each threaded rod 103 on the upper side is also inserted into the corresponding through hole 104. After screwing on the nut 106, the final assembly can be completed.

[0034] By splitting the test room and simplifying the assembly materials, the construction cost of the test room is reduced. The construction structure is simple, and the staff can operate the test room without relevant safety awareness, thereby greatly improving the assembly efficiency of the staff.
