[0002] An anechoic chamber is a device used for electromagnetic wave experiments and measurements. It is an enclosed room or box covered with special electromagnetic wave absorbing materials to prevent interference from external electromagnetic waves. The purpose of the anechoic chamber is to provide a space with little electromagnetic wave interference in a laboratory environment, so as to conduct precise electromagnetic wave measurements and research. In such an environment, scientists can better study the characteristics, propagation patterns and interactions of electromagnetic waves. The anechoic chamber is usually equipped with a high-flatness elevated floor structure to support the test equipment.

[0003] The existing high-flatness elevated floor structure is fixed. Although a lifting platform is installed at the bottom of the traditional elevated floor for lifting and adjusting the test equipment, some errors made by the workers during installation may cause the elevated floor to tilt. The traditional lifting platform cannot adjust the level of the elevated floor, so the installed elevated floor needs to be removed and reinstalled, which will waste more time and reduce work efficiency.

If the elevated floor main body 1 is tilted after the installation is completed, the corresponding handle 10 is turned on the side where the tilt is. After turning the handle 10, the rotating rod 8 can be driven to rotate, and the worm 9 on the rotating rod 8 can drive the turbine 7 to rotate. When the turbine 7 rotates, the folding rod 6 can be folded vertically to lift the elevated floor main body 1.

After the top block 14 is squeezed, the other end will extend to the outside of the base 3, so that personnel can discover and adjust it in time, and even slight deviations can be discovered.

[0028] like Figure 6 As shown, a scale line 15 is provided on one side of the top block 14. Through the setting of the scale line 15, the extended distance of the top block 14 can be clearly seen, so that the degree of rotation of the handle 10 can be judged according to the extended distance, which can improve the adjustment speed of the personnel.

[0029] like Figure 5 As shown, connecting holes 16 are provided on the fixing plate 11 and the horizontal rod 12, and an insert rod 17 is movably installed inside the connecting hole 16, and a block 18 is fixedly installed at one end of the insert rod 17.

Through the arrangement of the connecting plate 22 and the bolts 23, the elevated floor body 1 can be fixed to the connecting plate 22 by the plurality of bolts 23, which can improve the installation stability of the elevated floor body 1 and prevent it from loosening.

[0032] like Figure 2As shown, a support plate 24 is fixedly installed on the other side of the bracket 2, and an electric guide rail 25 is fixedly installed on the top of the support plate 24. A transmission block 26 is installed on the electric guide rail 25, and an electric telescopic rod 27 is fixedly installed on the top of the transmission block 26. A rotating frame 28 is fixedly installed on the output end of the electric telescopic rod 27, and a cleaning brush 29 is movably installed on the rotating frame 28.

[0035] In summary, in this embodiment, according to a high-flatness elevated floor structure adapted for an anechoic chamber, by providing the fixing plate 11, the horizontal rod 12, the through slot 13, and the top block 14, if the test equipment carried on the elevated floor main body 1 exerts uneven pressure on the elevated floor main body 1 during use, causing the elevated floor main body 1 to tilt, the horizontal rod 12 on the heavier side will descend and squeeze the top block 14. After the top block 14 is squeezed, the other end will extend to the outside of the base 3, so that personnel can promptly discover and adjust it. Even slight deviations can be found. By setting the scale line 15, the distance that the top block 14 extends can be clearly seen, so that the degree to which the handle 10 needs to be rotated can be judged according to the distance of the extension, which can improve the speed of personnel adjustment. By setting the connecting hole 16, the insertion rod 17 and the block 18, the insertion rod 17 is inserted into the inside of the connecting hole 16, and the insertion rod 17 is rotated so that the angle of the block 18 is adjusted to be perpendicular to the angle of the connecting hole 16, so that the horizontal rod 12 can be fixed on the fixing plate 11 to prevent it from falling off. The insertion rod 17 is rotated so that the horizontal rod 12 can be fixed on the fixing plate 11 to prevent it from falling off. The angle of the block 18 is adjusted to be consistent with the connection hole 16, so that it can be removed, which is convenient for disassembly and replacement when the horizontal rod 12 is damaged. It can increase the force area of ​​the other end of the plug rod 17, so that the hand is not easy to slip when the personnel rotate the plug rod 17, thereby facilitating the disassembly and installation of the plug rod 17. Through the setting of the connecting plate 22 and the bolt 23, the elevated floor body 1 can be fixed to the connecting plate 22 by multiple bolts 23, which can improve the stability of the installation of the elevated floor body 1 and prevent it from loosening. 25. The transmission block 26, the electric telescopic rod 27, the rotating frame 28 and the cleaning brush 29 are arranged. Starting the electric telescopic rod 27 to extend can drive the rotating frame 28 to rise above the elevated floor body 1, and then rotating the cleaning brush 29 to flip it to the top of the elevated floor body 1 and fit it, and then starting the electric guide rail 25 to move the transmission block 26. During the movement, the transmission block 26 can drive the cleaning brush 29 to clean the dust on the surface of the elevated floor body 1 to prevent dust from accumulating on the elevated floor body 1 and affecting its conductivity and appearance.
