AI Technical Summary

Technical Problem

Traditional contact temperature measurement devices are cumbersome to operate, labor-intensive, and prone to probe misalignment or poor contact during temperature measurement, resulting in unstable measurement data and difficulty in achieving fast and stable clamping and positioning, thus affecting temperature measurement efficiency and accuracy.

Method used

A convenient temperature measuring device was designed, which uses a vertically set temperature measuring column and clamping components. Through the linkage between the rotating arm and the clamping arm, combined with the automatic reset function of the torsion spring, it can achieve rapid clamping and automatic positioning, ensuring that the object being measured is stably in contact with the temperature measuring column, and improving the consistency and repeatability of temperature measurement.

Benefits of technology

The clamping component can automatically conform to the object being measured, ensuring stable placement and accurate contact with the temperature measuring column, reducing heat conduction loss, improving temperature measurement accuracy and response speed, and its compact structure facilitates assembly, thereby improving the stability and reliability of temperature measurement.
