Closing spring loading device for circuit breakers

Abstract

The present invention relates to a closing spring loading device of a breaker. The device comprises a foldable connecting rod unit of which one end is connected with the free end of a closing spring and the other end is reverse with the free end of the closing spring, wherein the foldable spring connecting rod unit comprises a foldable part allowing a main body thereof to be folded between one end and the other end and compressing the closing spring along with the unfolding operation of the main body; a loading cam rotating along one direction and compressing the foldable part to unfold the foldable connecting rod unit; a latch gear connected with the loading cam to enable the rotation thereof to be consistent with the rotation of the loading cam; a stop member jointed with the latch gear and limiting the latch gear to rotate along another direction; a loading handle independent with the loading cam and the latch gear to rotate; a feeding rod jointed with the latch gar and connected with the loading handle to transmit the torque coming from the loading handle to the latch gear, thereby enabling the latch gear to rotate along one direction.
