[0027] Specifically, the lifting mechanism includes a balance plate 13, a guide plate 14, and an electric telescopic rod 15. The guide plate 14 includes two, and the two guide plates 14 are symmetrically arranged on both sides of the driving screw 7. The two ends of the balance plate 13 are slidably clamped on the two guide plates 14, and the lower end of the balance plate 13 is connected to the support rod 9, the fixed end of the electric telescopic rod 15 is connected to the balance plate 13, and the movable end of the electric telescopic rod 15 is connected to the mounting plate 10. A sealing door (not shown in the figure) is provided on the front of the box body 1.

[0028] By setting up the box 1 and two soundproof boxes, installing the motor in the soundproof box, and installing the detection gear in the box 1, the interference of external noise on gear noise detection is effectively reduced. The second drive motor and drive screw are simple in structure and easy to operate. The electric telescopic rod 15 is used to lift and lower the mounting plate 10, so as to facilitate the separation of the detection gear 12 and the driving gear 5, thereby facilitating the replacement of the gear. At the same time, the setting of the electric telescopic rod 15 is also convenient for adapting to the installation of gears of different specifications for noise detection, and has higher adaptability.

[0029] In this embodiment, in order to improve the stability of the mounting plate 10, the electric telescopic rods 15 include two, and the two electric telescopic rods 15 are relatively arranged on the balance plate 13, and a guide column 16 is provided at the lower end of the mounting plate 10 between the two electric telescopic rods 15, and the guide column 16 is movably passed through the balance plate 13.

[0030] By increasing the number of electric telescopic rods 15 to two and further adding guide columns 16, it is helpful to provide stability for the mounting plate during the process of lifting up and down.

[0033] In this embodiment, a screw mounting plate 20 is provided in the box body 1 just below the driving gear 5 , and the end of the driving screw 7 away from the second driving motor 6 is rotatably connected to the screw mounting plate 20 .
