The present invention has following beneficial outcomes: the present invention provides power by the bracket being welded on circuit breaker case and passes
The installation site with the space of direction conversion and gear unit is passed, realizes that power inputs using the drive rod of setting, passes through connecting lever
Component realizes that the vertical of power exports simultaneously, is realized by the relative rotation of the gear unit of corresponding connecting lever component setting to level
It moves and is converted to the component of vertical motion, reduce closing operation power 1200N or so while realizing power direction conversion；Structure letter
Single, setting is reasonable, reliable transmission, while bracket is changed to a vertical chute and a circular hole by the sliding slot of original both direction,
The requirement on machining accuracy to bracket is reduced, it is low in cost.
Replacement further is freely rotated along pin shaft by two curved connecting plates in connecting lever assembly unit and two direct-connected plates
Horizontal sliding of the pin in sliding slot, on the one hand reduces gearing friction power, on the other hand can make to be driven more flexible, adaptivity
By force, convenient for assembly.
Detailed description of the invention
Fig. 1 is circuit breaker transmission device broken section structural schematic diagram of the present invention；
Fig. 2 is circuit breaker transmission device partial structural diagram of the present invention.
In figure: 1, breaker box shell 2, drive rod 3, pin III 4, pin II 5, connecting lever component 6, bracket 7, pin
I 8, silk 9, insulated pull rod component 10, curved connecting plate 11, pin shaft 12, direct-connected plate are adjusted.
Specific embodiment
The present invention is described in further detail with specific embodiment with reference to the accompanying drawing, and described is to of the invention
It explains rather than limits.
A kind of embodiment of breaker is as depicted in figs. 1 and 2 in the present invention, and breaker includes transmission device, transmission device
Including circuit breaker case 1, the bracket 6 welded together with circuit breaker case 1, originally preferably in case as depicted in figs. 1 and 2, branch
6 top of frame is provided with the round hole with the input that is used as power, and bottom end is provided with the sliding slot as power output, and top round hole
It is linked together by pin shaft II 4 and connecting lever component 5,5 upper end of connecting lever component is connected by pin III with drive rod, and lower end passes through
Pin I 7 is connected with adjustment silk 8, and pin I 7 is as in the sliding slot of 6 bottom end of bracket；Pass through between adjustment silk 8 and insulated pull rod component 9
It is threaded togather；The connecting lever component 5 includes two curved 10, pin shafts, 11, two direct-connected plates 12 of winning in succession, and three sets
Set meet it is claimed below: curved connecting plate 10 and direct-connected plate 12 are linked together by pin shaft 11, and two curved connecting plates 10 are as upper end
And with one heart, as lower end and concentric, curved connecting plate 10 can be freely rotated two direct-connected plates 12 with direct-connected plate 12 along pin shaft 11.
In practical operation in use, when driving input power that 2 level of drive rod is driven to move downward, 5 upper end of connecting lever component
Curved connecting plate 10 rotates counterclockwise under the action of pin III 3 along pin shaft 11, while the direct-connected plate 12 in its lower end has along 11 up time of pin shaft
The trend of needle rotation, but rotary motion is decomposed into movement straight down under the action of 6 bottom end sliding slot of pin I 7 and bracket, from
