Description

Technical Field

[0001] The present application relates to the technical field of dynamometer calibration equipment, and in particular to a dynamometer measurement and calibration device. Background Art

[0002] Dynamometers come in a variety of construction styles, but their core components are all curved, elastic steel sheets or helical springs. When an external force deforms the sheet or spring, a lever or other transmission mechanism drives the pointer to rotate. The position on the dial where the pointer stops represents the magnitude of the external force.

[0003] For example, Chinese utility model patent publication number CN221376933U discloses a measurement calibration device for a standard dynamometer. This device, through the provision of a calibration mechanism, can change the distance between the mounting platform and the base platform, thereby achieving stretching of the dynamometer. By comparing the data of the two dynamometers, the dynamometer that needs calibration can be calibrated.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the force gauge measurement and calibration device in the related technologies is difficult to implement calibration operations on two force gauges of different sizes, thereby reducing the practicality of the device.
