Abstract
The utility model discloses a spring actuating mechanism of a breaker. The spring actuating mechanism consists of an energy storing unit which is arranged on a splint mechanism formed by a mechanism front side plate and a mechanism back side plate, a transmission unit and a driving unit. Under the action of the force of an operating handle, a camshaft of the driving unit drives a cam and a ratchet wheel which are installed on the camshaft to move to elongate a closing spring to enable the mechanism to remain in an energy stored state. An output crank arm of the transmission unit is sleeved on a principal shaft on which a spline is connected with a switch crank arm; when an energy storing latch is pulled away from a disengagement groove of an energy storing half shaft, the closing spring releases the energy to drive the cam to continue to move; the movement is transferred to the output crank arm to drive the output crank arm to rotate so as to drive a gang switch crank arm to rotate; and a transmission crank arm is enabled to rotate through an insulated pull rod to push a vacuum arc extinguish chamber to close or break. The spring actuating mechanism is reasonable in design, simple in structure, reliable in breaking and closing operations, stable in performance, convenient in installation and long in service and requires no daily maintenance.
