Description
Technical Field
The utility model relates to the technical field of weighing apparatus verification, in particular to a lifting mechanism for weighing apparatus verification.
Background
The weighing apparatus verification is a process of testing and calibrating the weighing apparatus to ensure the accuracy and reliability of its measurement results. Weighing machines are commonly used to measure the mass or weight of an object, such as kitchen scales, industrial scales, and the like. Since time, environment, use, etc. may affect the accuracy of the weighing apparatus, it is important to perform the weighing apparatus calibration periodically, especially in the fields where high-precision measurement is required, such as laboratory, production line, etc.
Currently, balances are an important and common type of weighing apparatus, and play a critical role in accurate measurements in various fields. Therefore, it is particularly important for the periodic calibration of the balance. Although in many cases the balance is placed on a table top and the hands are directed to the central position of the dial by adjusting the left and right weights, this has certain limitations, and the table top serves as a platform for supporting the balance and cannot always ensure an absolute level. While the impact of such a tabletop may be relatively small for a typical balance, for a high precision balance, this minor instability may have a significant impact. In high precision measurements, any minor inaccuracy may lead to deviations in the measurement results, thereby affecting the accuracy and reliability of the results of the experiment, production or scientific research.
