Background technology
When pole-mounted circuit breaker manufactures, it is necessary to which main shaft and connecting lever are assembled together, current most of producers use hammer
Connecting lever directly is beaten, connecting lever is driven in main shaft, this mode is inconvenient, efficiency is low, does not reach industrialization.
The content of the invention
The purpose of this utility model is to provide the peace of the pole-mounted circuit breaker main shaft that a kind of technique is simple, easy for installation and connecting lever
Assembling structure.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of installation of pole-mounted circuit breaker main shaft and connecting lever
Structure, including main shaft, the connecting lever that is set in the main shaft, the outer contour of the main shaft are hexagon, the lubrication groove of the main shaft
Exterior feature is circle, and the connecting lever is the cylinder equipped with boss, and the outer contour of the cylinder and the Internal periphery of the main shaft were
It is full of cooperation, the free end of the connecting lever is arranged with frock, and the frock includes circular sleeve and circular sleeve lid, the circular set
Cylinder and the welding of circular sleeve lid, the top of the circular sleeve are equipped with circular sleeve chamfering, and the bottom of the circular sleeve lid is set
There is circular sleeve lid chamfering, the circular sleeve is long 125mm, outside diameter 38mm, the steel pipe of wall thickness 2.5mm, the circular sleeve
Cover as the plectane of diameter 38mm, thickness 4mm.
Further, the boss is equipped with two parallel triangular plates.
Further, the triangular plate is equipped with circular hole.
Further, the connecting lever is equipped with positioning key.
Compared with prior art, the beneficial effect of the mounting structure of the utility model pole-mounted circuit breaker main shaft and connecting lever is：
Frock manufacturing process and main shaft and connecting lever mounting process are simple, easy to use, efficient.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of frock in Fig. 1.
Fig. 3 is the schematic front view of frock.
Embodiment
Please refer to Fig.1 to Fig.3, a kind of mounting structure of pole-mounted circuit breaker main shaft and connecting lever, including main shaft 1, be set in master
Connecting lever 2 in axis 1, the outer contour of main shaft 1 is hexagon, and the Internal periphery of main shaft 1 is circle, and connecting lever 2 is the circle equipped with boss 21
Cylinder, the outer contour of cylinder are interference fit with the Internal periphery of main shaft 1, and boss 21 is equipped with two parallel triangular plates
22, triangular plate 22 is equipped with circular hole 23, and connecting lever 2 is equipped with positioning key 4, and positioning key 4 supports to limit boss with boss 21
21 axial movement.
The free end of connecting lever 2 is arranged with frock 3, and frock 3 includes circular sleeve 31 and circular sleeve lid 32, circular sleeve 31
Welded with circular sleeve lid 32, the top of circular sleeve 31 is equipped with circular sleeve chamfering 311, and the bottom of circular sleeve lid 32 is equipped with
Circular sleeve lid chamfering 321.Circular sleeve 31 is equal with the outside diameter of circular sleeve lid 32, and circular sleeve 31 is long 125mm, outside diameter
Positioning key on main shaft and main shaft can just be entangled, will not hindered by the steel pipe of 38mm, wall thickness 2.5mm, such circular sleeve 31
Connecting lever is hindered to be installed in place.Circular sleeve lid is diameter 38mm, the plectane of thickness 4mm, and when connecting lever is installed, connecting lever is packed into spindle end
Portion, then circular sleeve 31 is packed into spindle nose, then hit with a hammer circular sleeve lid 32, so that connecting lever is installed in place.
The advantages of the utility model is：Frock manufacturing process and main shaft and connecting lever mounting process are simple, easy to use, efficiency
It is high.
The advantages of basic principle and main feature and the utility model of the utility model has been shown and described above, for
For those skilled in the art, it is clear that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and without departing substantially from this
In the case of the spirit or essential attributes of utility model, the utility model can be realized in other specific forms.Therefore, no matter
