AI Technical Summary
Existing circuit breakers generate repetitive friction when rotating the adjustment switch, which affects the rotation efficiency, produces significant noise, and results in unstable operation due to the high friction force.
By incorporating a lubricant storage rubber frame within the circuit breaker, a measured amount of lubricant is extruded as the rotating disk rotates, lubricating the rotating connecting shaft, reducing friction, and fixing the orientation of the rotating disk. Combined with the design of a damping sliding rail and transmission block, this improves stability and lubrication performance.
It reduces frictional noise during switch status adjustment, improves the stability and lubrication effect of the circuit breaker, and avoids the adjustment of the rotating disc orientation due to accidental collisions.
