AI Technical Summary
Technical Problem
The main power switch of the existing dust measuring instrument calibration device is easily accidentally touched, causing sudden shutdown, affecting normal operation and damaging electronic components.
Method used
A mesh screen is installed above the main power switch. The mesh screen works in conjunction with a pressure plate and a guide rod to prevent accidental activation. A sliding assembly is used to limit the movement path of the pressure plate and reduce friction.
Benefits of technology
It effectively prevents accidental activation of the main power switch, avoids sudden shutdown, protects the calibration device from damage, and ensures normal operation.
