[0043] The combination of the adjusting part and the foot pad 122 can adapt to placement surfaces with different shapes and heights, the height of the foot pad 122 is adjusted flexibly, so that the body 20 reaches the best levelness and stability.

[0044] The elastic member 13 can be arranged between the adjusting member and the bottom shell 11, or arranged between the bottom shell 11 and the foot pad 122. The elastic member 13 (such as a spring) is sleeved on the adjusting member and can provide uniform support force in the axial direction, so that more effective buffering effect can be provided, and the leveling assembly 12 can maintain consistent elasticity and damping effect at different height positions.

[0045] In the embodiment of the utility model, the two ends of the elastic member 13 are connected with the lower surface of the bottom shell 11 and the foot pad 122 respectively.

[0046] It is worth noting that the lower surface of the bottom shell 11 refers to the surface of the side of the bottom shell 11 away from the mounting surface 111. Figure 4 In the embodiment, the elastic member 13 is located between the foot pad 122 and the lower surface of the bottom shell 11, and the elastic member 13 is connected with the foot pad 122 to provide a certain pre-tightening force for the foot pad 122, which can effectively prevent the foot pad 122 from loosening or falling off during use, especially when moving, transporting or being impacted, so as to ensure the stability and safety of the ultrasonic power meter 100.

[0047] Meanwhile, the elastic force of the spring can provide a pre-tightening force for the adjusting member, so that compensation force can be provided when a small gap is generated between the adjusting member and the bottom shell 11, so that the two are tightly attached to each other, accurate height adjustment is realized, and the device can always maintain the best levelness.

Figure 2

[0061] In the embodiment of the utility model, the elastic member 13 is a tower spring 131, the side surface of the foot pad 122 facing the bottom shell 11 is further provided with a connecting groove 1221, the tower spring 131 is sleeved on the outside of the adjusting member, and the diameter large end of the tower spring 131 is located in the connecting groove 1221.

[0062] In detail, Figure 4 The elastic member 13 is set as the tower spring 131, so that uniform pressure distribution can be provided in the compression process, and the leveling assembly 12 can keep consistent elasticity and damping effect at different height positions.

[0063] The tower spring 131 has higher load bearing capacity compared with an ordinary spring, can provide stable supporting force in a larger range, and is suitable for different placement surfaces and load conditions.

[0064] ​In a specific embodiment, by increasing the screw 121, the foot pad 122 and the tower spring 131, the hand screw 121 on the upper part of the bottom shell 11 is convenient to operate, and the elastic force generated by the tower spring 131 between the bottom shell 11 and the foot pad 122 can slow down the vibration of the foot pad 122, and the device can be used on most non-horizontal calibrated planes.

[0065] In the embodiment of the utility model, the leveling assembly 12 further comprises an anti-skid pad 125, and the anti-skid pad 125 is fixedly connected to the surface of the foot pad 122 away from the bottom shell 11.

[0067] The material of the anti-skid pad 125 can be rubber or silicone or other elastic materials, which can absorb vibration to some extent and provide additional shock absorption effect, further protecting the precise components inside the body 20.

[0068] At the same time, the anti-skid pad 125 can evenly disperse the pressure from the device and protect the placement surface from damage. By combining the anti-skid pad 125 with the tower spring 131 component, a multi-layer buffer system can be formed, enhancing the overall shock absorption performance.

[0069] In the embodiment of the utility model, the leveling assembly 12 is provided in multiple groups, and the multiple leveling assemblies 12 are all located outside the horizontal projection plane of the bottom shell 11 of the body 20 and are uniformly spaced around the center of the bottom shell 11.

The screws 121 on the outside can be independently adjusted in height without affecting the working state of the electronic balance, ensuring the accuracy of measurement.

[0071] In an embodiment, as Figure 1The leveling assembly 12 is provided with four groups, and the four groups of leveling assemblies 12 are arranged at four corners of the bottom shell 11 around the center of the bottom shell 11. That is, the four groups of screws 121 and foot pads 122 are distributed at the four corners of the bottom shell 11, and each group of screws 121 and foot pads 122 can be independently adjusted in height. The user can flexibly fine-tune the height of each corner according to the specific situation of the placement surface, so as to ensure that the ultrasonic power meter 100 always maintains the best levelness. Compared with single-point support, four-point support can better disperse weight and pressure, can provide uniform support force, and can ensure that the ultrasonic power meter 100 can maintain a stable horizontal state on different placement surfaces; four-point leveling provides more adjustment freedom, so that the leveling process is more fine and accurate, and the measurement accuracy is ensured.
