Description
Technical field
The present invention relates to a kind of submerged pump, and in particular to a kind of counnter attack Coupling Shaft structure of submerged pump.
Background technology
The output of submerged pump is generally connected as one by two connections of axle, upper axle and lower axle by upper and lower shaft coupling, but
Because submerged pump has in the presence of the possibility for reversely rotating in short-term in trial operation and parking, once reversely rotating, may result in up and down
Shaft coupling and upper axle and lower axle threaded connection unclamp, and cause the breaking-up of pump.
The content of the invention
It is an object of the invention to provide a kind of submerged pump spindle structure for preventing rotating shaft from inverting.
The technical scheme that the present invention takes is：
A kind of counnter attack Coupling Shaft structure of submerged pump, including upper axle, lower axle and upper and lower shaft coupling, the connection of the upper and lower axle
End is equipped with screwed hole, and the side of the connection end of upper and lower axle is provided with a circle screw hole, anti-reverse braking is connected with screw hole
Nail, the two ends of the upper and lower shaft coupling are respectively thread segment, and the end of each thread segment is respectively equipped with stopper slot, the stopper slot with
Screw hole correspondence.
Further, the upper and lower shaft coupling is provided with limit convex respectively with the spacing cooperation of end face of upper and lower axle connection end
Platform.
After taking above technical scheme, beneficial effects of the present invention are：Counnter attack has been installed additional on the upper and lower shaft coupling of connector
After the dynamic nail of the transformation of ownership, axial displacement can be prevented, ensure that the stability of pump.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
Specific embodiment of the invention is further described below in conjunction with accompanying drawing：
As illustrated, a kind of counnter attack Coupling Shaft structure of submerged pump, including upper axle 1, lower axle 2 and upper and lower shaft coupling 3, it is described
The connection end of upper and lower axle is equipped with screwed hole 4, and the side of the connection end of upper and lower axle is provided with a circle screw hole 5, upper and lower shaft coupling 3
Two ends be respectively thread segment 6, the end of each thread segment 6 is respectively equipped with stopper slot 7, and stopper slot 7 is corresponding with screw hole 5, screw
Anti-reverse braking nail 8 is connected with hole 4, anti-reverse braking nail 8 pushes against the bottom of stopper slot 7, and upper and lower shaft coupling 3 is provided with difference
With the positive stop lug boss 9 of the upper and lower axle connection end spacing cooperation of end face.
Claims (2)
