Abstract
The utility model relates to a submerged pump prevent anti - coupling shaft structure, including upper shaft, lower and upper and lower coupling head, the link of upper and lower axle all is equipped with the screw hole, and the side of the link of upper and lower axle is equipped with the round screw hole, and the screw hole internal rotation has connect the braking of preventing turing back to follow closely, and the both ends of upper and lower coupling head are the screw thread section respectively, and the end of each screw thread section is equipped with the spacing groove respectively, and the spacing groove corresponds with the screw hole.
Description
Technical field
The utility model is related 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
The purpose of this utility model is to provide a kind of submerged pump spindle structure for preventing rotating shaft from inverting.
The technical scheme that the utility model is taken is：
A kind of counnter attack Coupling Shaft structure of submerged pump, including upper axle, lower axle and upper and lower shaft coupling, the upper and lower axle
Connection 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 system is connected with screw hole
Dynamic 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
It is corresponding with screw hole.
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, the beneficial effects of the utility model are：Installed additional on the upper and lower shaft coupling of connector
After anti-reverse braking nail, axial displacement can be prevented, ensure that the stability of pump.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Specific embodiment of the present utility model 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, institute
The connection end for stating 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, and upper and lower axle connects
First 3 two ends are respectively thread segment 6, and the end of each thread segment 6 is respectively equipped with stopper slot 7, and stopper slot 7 is corresponding with screw hole 5, spiral shell
It is connected with anti-reverse braking nail 8 in nail 4, anti-reverse braking nail 8 pushes against the bottoms of stopper slots 7, upper and lower shaft coupling 3 is provided with point
Not with the positive stop lug boss 9 of the upper and lower axle connection end spacing cooperation of end face.
