Abstract
The utility model relates to an impeller part for a diving sewage drainage pump, in particular to a structure improvement of an impeller part, which comprises a shaft, a key, an impeller, an impeller pressure plate, a small screw and a big screw, and is characterized in that the impeller is connected on the shaft by the key, the impeller pressure plate is arranged in a counter bore which is arranged on the lower end of the impeller, the middle portion of the impeller pressure plate is provided with a big through hole, the big screw which is arranged in the big through hole is screwed in a big thread hole on a shaft end passing through the impeller, the side of the impeller pressure plate is provided with a small through hole, a corresponding position of the impeller is provided with a small thread hole, and the small screw is screwed in the small thread hole through passing through the small through hole. The impeller part for the diving sewage drainage pump has the advantages that the impeller pressure plate and the impeller are fixed by the small screw to relatively rotate, thereby guaranteeing the impeller pressure plate and the impeller not to fall.
Description
Technical field
The utility model relates to a kind of wheel member that is used for proof submersible sand discharging pump, particularly to the improvement of wheel member structure.
Background technique
In proof submersible sand discharging pump, generally impeller and axle are fixed together by impeller pressing plate and screw.Be an impeller rotation during starting mode of pump, impeller impeller pressing plate rotation again has relative rotation between the two, because screw is pressed on the impeller pressing plate, screw also can be followed relative rotation, thereby causes screw loosening, time grown after screw will come off, cause water pump to use.
Summary of the invention
The purpose of this utility model is to make between impeller and the impeller pressing plate can not relatively rotate, and a kind of novel wheel member structure is provided.The utility model designs a kind of novel wheel member with locking functions, comprise axle, key, impeller, impeller pressing plate, Screw, big screw, it is characterized in that: impeller is mounted on the axle by key, the impeller pressing plate is positioned at the counterbore of impeller lower end, there is large through-hole the centre of impeller pressing plate, having big screw to pass impeller in the large through-hole twists and to be connected in the major thread hole of axle head, the impeller pressing plate small through hole arranged on the limit, opposite position has the minor thread hole on impeller, and Screw passes small through hole and twists and to be connected in the minor thread hole.The utility model has the advantages that and utilize Screw to fix relatively rotating of impeller pressing plate and impeller, guarantee that impeller pressing plate and impeller do not come off.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Accompanying drawing one is an impeller pressing plate schematic representation; Accompanying drawing two is the impeller schematic representation; Accompanying drawing three is use principle figure.
1 is axle among the figure, and 2 is key, and 3 is impeller, and 4 is Screw, and 5 is big screw, and 6 is the impeller pressing plate, and 7 is large through-hole, 8 small through hole.9 is the minor thread hole, and 10 is counterbore, 11 major thread holes.
Embodiment
Comprise axle, key, impeller, impeller pressing plate, Screw, big screw among the figure, it is characterized in that: impeller is mounted on the axle by key, the impeller pressing plate is positioned at the counterbore of impeller lower end, there is large through-hole the centre of impeller pressing plate, having big screw to pass impeller in the large through-hole twists and to be connected in the major thread hole of axle head, the impeller pressing plate small through hole arranged on the limit, opposite position has the minor thread hole on impeller, Screw passes small through hole and twists and be connected in the minor thread hole.At first key and impeller are installed on the axle during use, again the impeller pressing plate is placed in the counterbore of impeller, small through hole on the impeller pressing plate aligns with the minor thread hole on the impeller, big screw is passed in the major thread hole of middle large through-hole of impeller pressing plate and precession axle head, Screw is passed in the minor thread hole of small through hole on the impeller pressing plate limit and precession impeller end, two screws all will screw.Impeller pressing plate and impeller just have been fixed together by Screw like this, and stopping of Screw arranged, and just can not take place to have rotated relatively between the two, and Screw are all very convenient when installation and removal.The specification of Screw is M6 or M8, and the diameter of big screw is about 1/3rd of the diameter of axle, so just can satisfy the intensity needs.
Claims (1)
