Description
Technical field
The utility model relates to a kind of fan structure.
Background technique
The internal structure of existing fan is: outer frame bottom installation shaft core and stator, on flabellum, assemble rotor, and add upper spring, pad and clasp flabellum is fitted together by assemble ball bearing on axle core.Axle core and the housing of existing structure are one, and first rotor on flabellum is pressed into the aluminium flake on flabellum and then stamping rotor, completes the assembling of rotor and flabellum.This structure difficulty of processing is larger, and also comparatively complicated in assembly process, cost is higher, meanwhile, because stator is to fix by glue and flabellum, not quick detachable while causing follow-up maintenance, brings difficulty to later maintenance.
Model utility content
The purpose of this utility model is to overcome the defect of prior art, and a kind of fan structure is provided, and has reduced the difficulty of processing of fan, has simplified assembly process, has saved cost, is easy to dismounting, is convenient to later maintenance.
The utility model is achieved in that a kind of fan structure, and it comprises:
Housing, described housing is provided with middle pipe, and described housing and described middle pipe are one-body molded;
Flabellum, described flabellum is provided with axle core, and described axle core is fixedly connected with described flabellum, and described axle core is arranged in described middle pipe;
Be provided with clasp, described clasp is arranged at described axle core end, and is arranged in pipe bottom.
Further, described middle bore two ends are large, and middle part is little, the inwall two ends stepped of described middle pipe.
Further, be provided with stator, described stator is arranged at the outside of described middle pipe.
Further, be provided with ball bearing, described ball bearing quantity is 2, and described ball bearing is arranged on described axle core, and described ball bearing is connected to respectively the step at middle inner tube wall two ends.
Further, be provided with pad, described pad quantity is 2, and described pad is arranged on described axle core, and described pad is connected to respectively 2 ball bearings.
Further, be provided with spring, described spring is arranged on described axle core, and described spring is arranged between described flabellum and described pad.
The utility model provides a kind of fan structure, and it comprises: housing, and described housing is provided with middle pipe, and described housing and described middle pipe are one-body molded; Flabellum, described flabellum is provided with axle core, and described axle core is fixedly connected with described flabellum, and described axle core is arranged in described middle pipe; Be provided with clasp, described clasp is arranged at described axle core end, and is arranged in pipe bottom.By axle core is arranged on flabellum, and flabellum is fixed in described housing by the structure of clasp and housing fastening at axle core end, assembles with this structure, reduce difficulty of processing, simplified assembly process, saved cost, be easy to dismounting, be convenient to later maintenance.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiments that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
In concrete application, as shown in Figures 1 and 2, an embodiment of a kind of fan structure of the utility model, housing 6 provides accommodation space for fan internal structure, and fan internal structure is played to isolation and protective action.Described housing 6 bottoms arrange middle pipe 61, and described housing 6 and described middle pipe 61 are one-body molded, and described middle pipe 61 internal diameter two ends are large, and middle part is little, the inwall two ends stepped of described middle pipe 61.Described middle pipe 61 play fixed supporting role to flabellum 1 and stator 5.
Flabellum 1 is provided with axle core 11, and described axle core 11 is fixedly connected with described flabellum 1, and described axle core 11 is arranged in described middle pipe 61.Described axle core 11, by the fixed support of middle pipe 61, ensures the stable rotation of flabellum 1.
Clasp 7 is arranged at described axle core 11 ends, and clasp 7 is fixed on axle core 11 among middle pipe 61 after fastening, and makes within flabellum 1 is fixed on housing 6 in the process of rotating.
Stator 5 is arranged at the outside of described middle pipe 61, and stator 5 for fan provides kinetic energy, drives flabellum 1 to rotate by electromagnetic induction.
Ball bearing 4 is arranged on described axle core 11, and described ball bearing 4 is connected to respectively the step at middle pipe 61 inwall two ends, and it is fixing that described ball bearing 4 plays retainer shaft central position to described axle core 11, and can effectively reduce load and the friction of axle core 11.
Pad 3 is arranged on described axle core 11, and described pad 3 is connected to respectively two ball bearings 4, and pad 3 shields to ball bearing 4, and can effectively reduce the load of ball bearing 4.
Spring 2 is arranged on described axle core, and described spring 2 is arranged between described flabellum 1 and described pad 3, by the spring damping of described spring 2, has effectively slowed down the pushing of flabellum 1 to housing 6, and slows down the pressure between each parts on axle core 11.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
