Technical Field

[0001] The utility model relates to the technical field of variable resistors, and particularly relates to a mechanism for measuring the stroke of a sliding rheostat in a lifting mechanism. Background Technique

[0002] In the existing industrial automation and precision control fields in life, a lifting mechanism is a common mechanical device used to move objects in the vertical direction. These mechanisms are widely used in production lines, assembly lines, laboratory equipment, and various occasions requiring precise positioning. A sliding rheostat is a common electronic component used to adjust the resistance value in a circuit.

[0003] In a lifting mechanism, a sliding rheostat may be used as a position sensor to monitor the position or motion state of the lifting mechanism by detecting changes in the resistance value. When the existing sliding rheostat is in use, it is adjusted to achieve the desired use effect, but there is no defect value to enable precise adjustment, which is likely to cause unstable adjustment and unable to reach the required height and experimental values during lifting.
