Embodiment
Below in conjunction with drawings and Examples, describe the present invention.
A kind of contents transmission device for circuit breaker of the present invention, wherein: the contents of circuit breaker comprises release 5, shell 1, release actuated piece 6, release push rod 7 and circuit breaker draw bar 8; Contents transmission device for circuit breaker comprises driving member 3 and back-moving spring 4, driving member 3 comprises the push rod contact site 9 that contacts with release push rod 7 all the time and the draw bar pushing part 10 for promoting circuit breaker draw bar 8 when circuit malfunctions, driving member 3 can freely rotate, back-moving spring 4 is fixed on driving member 3 relatively, its one end is connected on driving member 3, the other end is connected on shell 1, and back-moving spring 4 makes driving member 3 contact with release push rod 7 all the time.
As shown in Figure 1, its assembly structure as shown in Figures 2 and 3 for embodiment of the present invention structure.
In this embodiment, adopt a pressing plate 2 as shown in Figure 6 and the formation cavity that matches bottom shell 1, the mode forming cavity can be only at pressing plate bottom slot, also can be only at shell bottom slot, but the groove (as shown in Figure 4 and Figure 6) of semicircle arcuation is preferably set with outer casing bottom bottom pressing plate simultaneously, a common formation cavity after the two split.Match with it, driving member 3 can be arranged protruding 11 or rotation axis or other shaft-like structure, the present embodiment is only described with the situation arranging protruding 11.On driving member, the projection 11 of 3 is arranged in cavity, coordinates with cavity, can realize the axial location of driving member 3.This cavity is preferably cylindrical, and cylindrical cavity and driving member 3 are matched in clearance, makes driving member 3 can flexible rotating.
