The spring operating mechanism of the utility model adopts following technical scheme: a kind of spring operating mechanism; Comprise frame; Said frame comprises through bolt and being used for and fixing base plate of Shell of circuit breaker and the left and right side plate that extends along the frame fore-and-aft direction that is vertically set on the base plate both sides; Between the left and right side plate, also vertically be provided with the front vertical plate, middle riser and the back vertical plate that extend along the frame left and right directions and distribute from front to back on the base plate; Offer the main shaft that is used for closing a floodgate in said on riser and the back vertical plate and run through the combined floodgate spindle hole of riser and back vertical plate; It is characterized in that: be wholely set gusset on the continuous direction of the screwed hole that said base plate upper edge bolt passes; Said screwed hole is laid on the gusset, is wholely set the arc gusset that extends along the frame left and right directions and join with said front vertical plate with said front vertical plate joint on the said base plate, said on riser and the back vertical plate equal one be provided with along the annular gusset of combined floodgate spindle hole circumferential directions.
Said middle riser rear side is positioned at combined floodgate spindle hole edge and evenly is laid with many bar shaped gussets that extend along combined floodgate spindle hole radial direction along combined floodgate spindle hole circumferencial direction.
Screwed hole on the said base plate is 4, and said gusset forms rectangular frame along the continuous direction of 4 screwed holes.
Adopt the frame of above-mentioned breaker spring operating mechanism; The continuous direction of the base plate upper edge screwed hole of frame has been wholely set gusset; The joint of base plate and front vertical plate has been wholely set the arc gusset, is positioned at combined floodgate spindle hole place on middle riser and the back vertical plate and is wholely set along the annular gusset of combined floodgate spindle hole circumferential directions, and gusset, arc gusset and annular gusset are all at the stress concentrated position place of frame; Effectively avoided stress to concentrate through these gussets, the intensity of frame is significantly improved.Adopt the spring operating mechanism of this frame also to have same effect simultaneously.
