Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing: as shown, a kind of isolation axis transmission structure, including
Alternate shell 1 and isolation axis 2, the alternate shell are equipped with perforative holding tank 3, are equipped with quiet contact point 4 in the holding tank,
Being equipped in the holding tank can be correspondingly provided with dynamic along the casing 5 of own axis, described sleeve pipe outer wall with the quiet contact point
Contact 50, the isolation axis drive described sleeve pipe rotation when passing through described sleeve pipe and isolation axis rotation.Outdoor high-voltage open circuit
It is set in device there are three alternate shell, is the prior art, is directly contacted in the prior art with alternate shell by the way that axis is isolated, to isolation
Axis machining accuracy is difficult to if having higher requirement, whole in this way isolation axis to have high requirement.The casing is directly arranged
It is much lower to the dimension precision requirement of isolation axis in alternate shell, and when installation, isolation axis need to only be passed through
Casing, then rotation isolation axis can drive casing to rotate, and structure is simple, easy to use.On the other hand, the kind of drive
The cross section that can be the isolation axis is non-circular geometric face, such as polygon or ellipse etc., and thus rotation drives casing one
Play rotation.
In the present invention, as shown, the isolation shaft cross section is polygon.The polygon can be triangle
Shape, regular hexagon, octagon etc. can select according to actual needs.
In the present invention, as shown, being extended with convex block 21, the set along its length on the isolation axis outer wall
Inside pipe wall is equipped with the groove 51 with the convex block clearance fit.It can also be driven using similar key to drive casing to rotate, herein
Using convex block, when axis insertion casing is isolated, which can be fallen into groove, when axis rotation is isolated, pass through convex block band
Dynamic casing rotation.
