Abstract
Impeller screw loosening structure is prevented the utility model discloses one kind, including impeller, mounting hole is offered in the center of the impeller, on the output shaft that impeller is arranged on to motor by screw through mounting hole, being provided with the mounting hole prevents the anti-loose structure of screw loosening.The utility model can effectively prevent the situation that screw is loosened due to the vibration of motor, have a safety feature strong with practical performance.
Description
Technical field
The utility model is related to submersible pump technical field, and being related specifically to one kind prevents impeller screw loosening structure.
Background technology
Submersible pump is pump housing impeller and drives the motor of impeller all to pull the plug a kind of water pump of work, have deep-well use and
The scope of operation is with two kinds.Deep Submersible Pump is powered by the cable stretched into well to motor, eliminates transmission long axis, thus knot
Structure is compact, lightweight, install, using and convenient transfer, in the trend for having the substituted borehole shaft driven (centrifugal) pump in power supply area.
The impeller of submersible pump of the prior art is mostly to be directly installed on by screw on the output shaft of motor,
Motor operationally easily vibrates, and is used to impeller being fixed on the screw on the output shaft of motor due to the vibration of motor
Easily loosen, be not only difficult to the normal work of impeller, also there is larger potential safety hazard.
But in view of the shortcomings of the prior art, developer be necessary to develop it is a kind of it is reasonable in design, simple in construction, can be effective
Prevent situation that screw is loosened due to the vibration of motor, have a safety feature with practical performance by force prevent impeller screw
Loosen structure.
Utility model content
To solve the problem of prior art is present, the utility model purpose provides a kind of reasonable in design, simple in construction, energy
Enough situations for effectively preventing that screw from being loosened due to the vibration of motor, have a safety feature with practical performance by force prevent leaf
Take turns screw loosening structure.
To solve above technical problem, what the utility model was realized using following technical scheme：
One kind prevents impeller screw loosening structure, including impeller, and mounting hole is offered in the center of the impeller, leads to
Cross screw to be arranged on impeller through mounting hole on the output shaft of motor, it is characterised in that being provided with the mounting hole prevents
The anti-loose structure of screw loosening.
In a preferred embodiment of the present utility model, the anti-loose structure includes elastomeric pad and snap ring, described
Annular groove is offered on the inwall of mounting hole, the snap ring is connected on annular groove, it is in mounting hole that the elastomeric pad, which is set,
It is interior and positioned between snap ring and screw.
In a preferred embodiment of the present utility model, the elastomeric pad is rubber sheet gasket.
Compared with prior art, the utility model is provided with mounting hole prevents the anti-loose structure of screw loosening, anti-untwisting
Structure includes elastomeric pad and snap ring, annular groove is offered on the inwall of mounting hole, snap ring is connected on annular groove, elastomeric pad
Setting is, in mounting hole and positioned between snap ring and screw, can effectively to prevent screw due to the vibration of motor using such a
And situation about loosening, further increase the security performance and practical performance of submersible pump.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is enlarged drawing at Fig. 1 A.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Shown referring to Figures 1 and 2, the one kind provided in figure prevents impeller screw loosening structure, including impeller 100, in leaf
The center of wheel 100 offers mounting hole 110.
On the output shaft 300 that impeller is arranged on to motor from screw 400 through mounting hole 110, set in mounting hole 110
There is the anti-loose structure for preventing that screw 400 from loosening.
Anti-loose structure includes elastomeric pad 210 and snap ring 220, and annular groove 111 is offered on the inwall of mounting hole 110,
Snap ring 220 is connected on annular groove 111, and it is in mounting hole 110 and positioned at snap ring 220 and screw 400 that elastomeric pad 210, which is set,
Between, using such a situation that can effectively prevent screw 400 from being loosened due to the vibration of motor, further increase
The security performance and practical performance of submersible pump.
Elastomeric pad 210 is rubber sheet gasket, is capable of the vibration force of effective buffer motor, it is to avoid vibration force is transferred to screw
On 400, the security performance of submersible pump is further increased, elastomeric pad 210 can also be made from other elastomeric materials.
The utility model is provided with the anti-loose structure of screw loosening is prevented in mounting hole in summary, and anti-loose structure includes bullet
Property pad and snap ring, annular groove is offered on the inwall of mounting hole, snap ring is connected on annular groove, elastomeric pad set be
In mounting hole and positioned between snap ring and screw, effectively it can prevent screw from pine occurring due to the vibration of motor using such a
Dynamic situation, further increases the security performance and practical performance of submersible pump.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, the utility model can also on the premise of the utility model spirit and scope are not departed from
There are various changes and modifications, these changes and improvements are both fallen within the range of claimed the utility model.The utility model will
Protection domain is asked to be defined by appended claims and its equivalent.
