End sets the first long strip through hole；The spring is through in the spring installation axle；The rotating shaft is arranged on the low voltage isolation switch
Top, radially can freely rotate；The galianconism, it is long-armed be respectively and vertically fixed in the rotating shaft, both are parallel to each other；
The bottom of the first axle be fixed on it is described it is long-armed on, its top is fixed on the free end of the galianconism；The first axle is passed through
The first long strip through hole set in the spring installation axle；The long-armed free end is provided with the second long strip through hole, described second
Axle can be slided under the promotion of the driving lever along second strip hole；The long-armed bottom is fixed and is formed with circular cylindrical projection
Rise.
Specifically, the bottom of second axle is formed with chassis or fixture block；Formed on the second strip hole inwall
There is the groove matched with the base plate or fixture block；Base plate or fixture block are slided along groove.
Or following connected mode can also be changed into：The second axle bottom sets groove, and the inside of second strip hole sets
There is track, groove slides along the track.
The energy-stored spring operating mechanism of the low voltage isolation switch be using the idle stroke in spring installation axle and rotary shaft come
Ensure that the operation speed of operating personnel is unrelated with the action of switch, contact quickly divided, closed, it is to avoid to occur keeping apart
Close contact burnout failure.In addition, also there is reasonable in design, simple, low cost, without entering to former low voltage isolation switch structure
The advantages of row is changed.
Brief description of the drawings
The stereogram of the energy-stored spring operating mechanism of the low voltage isolation switch that Fig. 1 is provided for the present invention；
The working state figure of the energy-stored spring operating mechanism of the low voltage isolation switch that Fig. 2 is provided for the present invention.
Specific embodiment
Technical scheme is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, the energy-stored spring operating mechanism of a kind of low voltage isolation switch, installed in the top of low voltage isolation switch
Portion, including operating shaft 1, driving lever 2 and stroke compensating unit 3；
The bottom of operating shaft 1 is arranged on the top of low voltage isolation switch, radially can freely rotate；
Driving lever 2 has two, the orthogonal and fixed bottom for being arranged on operating shaft 1；
Stroke compensating unit 3 includes spring installation axle 301, spring 302, rotating shaft 303, galianconism 304, long-armed 305, first axle
306th, the second axle 307 and cylindrical protrusions 308；Spring installation axle 301 is hinged in operating shaft 1, positioned at the upside of driving lever 2；Spring
The free end of installation axle 301 sets the first long strip through hole 309；Spring 302 is through in spring installation axle 301；Rotating shaft 303 is arranged on low
The top of disconnecting switch is pressed, radially can freely be rotated；Galianconism 304, long-armed 305 are respectively and vertically fixed in rotating shaft 303, and two
Person is parallel to each other；The bottom of first axle 306 is fixed on long-armed 305, and its top is fixed on the free end of galianconism 304；First axle
306 pass through the first long strip through hole 309 set in spring installation axle 301；Long-armed 305 free end is provided with the second long strip through hole
310, the second axle 307 can be slided under the promotion of driving lever 2 along the second strip hole 310；Long-armed 305 bottom is fixed and is formed with cylinder
Shape projection 308.
Specifically, the bottom of the second axle 307 is formed with chassis or fixture block；It is formed with the inwall of second strip hole 310
The groove matched with base plate or fixture block；Base plate or fixture block are slided along groove.
Or following connected mode can also be changed into：The bottom of second axle 307 sets groove, and the inside of the second strip hole 310 is provided with
