AI Technical Summary
Existing portable gas measuring instruments lack effective protection mechanisms when not in operation, making them susceptible to interference from external factors. This can lead to accidental power-on or entry into incorrect operating modes, resulting in data confusion and inaccuracy, affecting normal equipment use and posing safety hazards.
An operating mechanism including a fixed component and a sliding component is designed. The sliding cover pushes the barb into the support frame, lifts the limit block and compresses the spring to store energy. Finally, the limit block locks the sliding cover, covering the operation panel and preventing accidental button touches.
It effectively prevents accidental operation, ensures the stability of the device when it is not in operation, reduces wear and tear on buttons due to invalid operations, extends the service life, and provides multiple portability options to improve the user experience and safety.
