Abstract
The utility model relates to an impeller locking device of a water pump, comprising a shaft, left-hand threads at both ends of the shaft, an impeller and an impeller nut. The utility model is characterized in that a perforation is arranged axially at the eccentric point on the top of the impeller nut, a bolt is arranged in the perforation and the front point of the bolt is contacted with the shaft. The utility model has the advantages that when the impeller nut is extended to loosen, a pushing force is produced to fasten the impeller nut and prevent the impeller nut from loosening and falling off.
Description
Technical field
The utility model relates to the impeller anti-loose device of a kind of locking device, particularly a kind of water pump.
Background technique
The impeller of water pump is to be vertically mounted on the axle, thereby compresses impeller by the screw-thread fit on impeller nut and the spindle nose then, makes the fixing and rotation thereupon of impeller and axle.Usually the loosening and way that cause running well of impeller nut is that thread rotary orientation is processed as direction with the impeller switched in opposite in order to prevent to rotate; in theory along with rotation; impeller nut can be more and more tighter; but in the running of reality; can produce the power that nut is got loose owing to have a process of slowing down gradually when shutting down; and the running back also has factors such as vibrations, is insecure so light has reverse thread.So lockingly can also take modes such as steel-wire screw-socket and lock washer, but the steel-wire screw-socket price comparison is expensive, and will process special-purpose screw, relatively difficulty, and the impeller front end does not have enough spaces to place lock washer yet, therefore must consider to take to solve the problems referred to above with other modes.
Summary of the invention
The purpose of this utility model is that the impeller that solves water pump in the prior art still can produce loosening problem to be fixed in the rotating shaft in the reverse screw thread of sense of rotation, and a kind of impeller anti-loose device of water pump is provided.The utility model designs a kind of impeller anti-loose device of water pump, comprise axle, axle head left-hand thread, impeller, impeller nut, it is characterized in that: eccentric part is offered a through hole vertically on the top of impeller nut, and a screw is arranged in through hole, and the front tip of screw is inconsistent with axle.The utility model has the advantages that when impeller nut has the trend that gets loose, can produce a pressure and reach the purpose of fastening impeller nut, prevent getting loose of impeller nut.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise axle 1, axle head left-hand thread 2, impeller 3, impeller nut 4 among the figure, it is characterized in that: offer a through hole 5 vertically at the top of impeller nut 4 eccentric part, a screw 6 is arranged in through hole 5, the front tip of screw 6 is inconsistent with axle 1.
Owing to be to offer a through hole 5 at the top of impeller nut 4 eccentric part, the screw 6 that therefore withstands on the axle 1 can moment of generation be offset the loosening rotating force that produces when impeller nut 4 has the trend that gets loose, and prevents getting loose of impeller nut 4.
Claims (1)
