Title:
SPRING-OPERATED MECHANISM, CLOSING LATCH SYSTEM, AND CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2022/028228
Kind Code:
A1
Abstract:
The present invention relates to a spring-operated mechanism, a closing latch system, and a circuit breaker. The spring-operated mechanism comprises a frame, on which an output shaft, a sector plate rotating shaft, and an opening half shaft which are parallel to each other are disposed; a transmission crack arm is disposed on the output shaft, and the transmission crank arm is provided with a holding arm; a notch is formed on the opening half shaft, and the bottom of the notch is a flat surface; a sector plate is disposed on the sector plate rotating shaft, a sector plate return spring is disposed between the sector plate and the frame, the sector plate is provided with a holding protrusion and a half shaft matching portion, the half shaft matching portion has a matching surface, and the matching surface is used for matching with the flat surface of the notch; the matching surface is an arc-shaped surface, and the center line corresponding to the arc-shaped surface coincides with the axis of the sector plate rotating shaft. In a forward rotating process of the half shaft matching portion, the opening half shaft will not be hit, so that the opening half shaft can rotate forward immediately after the half shaft matching portion is disengaged from the opening half shaft, so as to ensure to stop the half shaft matching portion that is reversely rotated back.
