[0002] The utility model discloses a fixing device for verifying a sound calibrator, which is a device used to fix the sound calibrator verification equipment when the equipment is plugged into a base.

[0003] Based on the above, the inventors found that: currently, there are many sound calibrator calibration fixing devices on the market, but in the actual operation of general sound calibrator calibration equipment, staff are required to manually support the sound calibrator calibration equipment and install it on the internal plug-in of its base. Therefore, staff are very likely to have slight shaking, which affects the normal calibration of the sound calibrator calibration equipment and reduces the practicality of the device. Therefore, in view of this, research and improvement are carried out on the existing structure to provide a sound calibrator calibration fixing device in order to achieve a more practical purpose.

[0031] As attached Figure 1 and Figure 4 As shown, two support plates 6 are provided at the bottom ends of the two fixed plates 31, the outer surfaces of the four support plates 6 are fixed to the outer walls of the pillars 2, and the inner walls of the four support plates 6 are provided with limiting columns 7. The top ends of the four limiting columns 7 are fixed to the bottom ends of the fixed plates 31, and the vertical cross-sectional area dimensions of the outer walls of the four limiting columns 7 are matched with the vertical cross-sectional area dimensions of the inner walls of the support plates 6, so as to improve the tightness of the connection between the top ends of the pillars 2 and the fixed plates 31.
