Specific embodiment
The present invention will be further explained below with reference to the attached drawings: as shown, a kind of isolation axis transmission structure, including it is alternate
Shell 1 and isolation axis 2, the alternate shell are equipped with perforative holding tank 3, and quiet contact point 4 is equipped in the holding tank, described
Moving contact can be correspondingly provided with along the casing 5 of own axis, described sleeve pipe outer wall and the quiet contact point by being equipped in holding tank
50, the isolation axis drives described sleeve pipe rotation when passing through described sleeve pipe and isolation axis rotation.In outdoor high voltage circuit breaker
If being the prior art, directly being contacted in the prior art with alternate shell by the way that axis is isolated there are three alternate shell, isolation axis is added
Work precision is difficult to if having higher requirement, whole in this way isolation axis to have high requirement.The casing is set up directly on phase
Between in shell, it is much lower to the dimension precision requirement of isolation axis, and when installation, only isolation axis need to be passed through casing
, then rotation isolation axis can drive casing to rotate, and structure is simple, easy to use.On the other hand, which can be with
Cross section for the isolation axis is non-circular geometric face, such as polygon or ellipse etc., and thus rotation drives casing to turn together
It is dynamic.
In the present invention, as shown, the isolation shaft cross section is polygon.The polygon can be triangle, just
Hexagon, octagon etc. can select according to actual needs.
In the present invention, as shown, being extended with convex block 21 on the isolation axis outer wall along its length, in described sleeve 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, be used herein
Be convex block, when be isolated axis insertion casing when, which can fall into groove, when be isolated axis rotation when, pass through convex block drive set
Pipe rotation.
In the present invention, as shown, the alternate shell two sides are equipped with end cap 6, described in two end caps coverings
Holding tank both ends are equipped with through-hole 61 on two end caps, and described sleeve pipe both ends are rotatably set to two through-holes
It is interior.Thus casing both ends can cooperate with the via clearance realizes rotation.
In the present invention, as shown, described sleeve pipe outer wall is arranged with sealing element 55, the end cap inner wall is equipped with mounting groove
62, the sealing element peripheral outer wall and mounting groove inner circumferential wall sealing cooperate.Sealing effect is more preferably.
