Abstract
A hub structure of a fan leaf consists of a hub which has an accommodation part and a plurality of leaves which are arranged at the outer margin of the hub; and an iron circle which is provided with a magnetic body is provided at the center of the accommodation part; the end surface of the accommodation part is provided with a plurality of blocks; and at least one buckling parts are arranged at proper position of the end surface of the accommodation part, the inner margin of which is provided with a plurality of ribs; the iron circle is provided with a perforation, one end margin of which is provided with a blocking part. A groove which is buckle-connected with a buckling part is provided between the buckling part and the magnetic body. The utility model is a hub structure of a fan leaf, which makes the whole structure fixing and not easy to loose, and also reach the efficacy of easy assembling.
Description
Technical field
The utility model relates to a kind of wheel hub structure of flabellum, refers in particular to a kind of structure of electric fan wheel hub.
Background technique
General fan hub structure is announced No. 395625 " fan motor with fixed function " as the TaiWan, China patent gazette, and it comprises:
One framework;
One impeller is positioned at framework;
One shaft-cup is positioned at impeller;
One axle sleeve, an end is connected on the framework;
One stator is positioned at shaft-cup, and is socketed on the axle sleeve;
One printed circuit board (PCB) between stator and framework, and is socketed on the axle sleeve;
And one first fixture, between shaft-cup and stator, be fixed on the axle sleeve with snap fit, stator shaft orientation is fixed;
One second fixture between stator and printed circuit board (PCB), passes axle sleeve, and cooperates the axial restraint of stator, and printed circuit board (PCB) can be fixed on the framework.
Though above-mentioned " fan motor with fixed function " can be fixed in printed circuit board (PCB) on the framework, because shaft-cup is shaft-cup could be fixed in the impeller inner cover by several grabs in several perforates cooperation impeller inner covers of its end face.Therefore, when shaft-cup must could be fixed in several perforates in the impeller inner cover shaft-cup by several grabs in the complete corresponding impeller inner cover when assembling, so inconvenient in assembling.
The model utility content
The purpose of this utility model just is: a kind of structure of flabellum wheel hub is provided, can makes overall structure firm, be difficult for getting loose, and reach the effect that is easy to assemble.
In order to achieve the above object, the solution that the utility model proposes is: a kind of structure of flabellum wheel hub, it is made of wheel hub and several blades that are arranged at the wheel hub outer rim with holding part, and the holding part centre is provided with an axostylus axostyle, and is provided with an iron ring with magnetic in holding part; The holding part end face has several blocks, and is provided with at least one buckling part in holding part end face appropriate location, and the holding part inner edge is provided with several ribs; Iron ring has a penetration hole, and an ora terminalis of penetration hole has a blocked part, and has a groove between magnetic and blocked part; Buckling part can be buckled in the groove.

Embodiment
To shown in Figure 5, a kind of structure of flabellum wheel hub is made of the iron ring (2) that a flabellum (1) and has magnetic (21) as Fig. 1.Flabellum (1) is made of the wheel hub with holding part (111) (11) and several blades (12) that is arranged at wheel hub (11) outer rim, and holding part (111) centre of wheel hub (11) is provided with an axostylus axostyle (13), and be provided with several blocks (112) in holding part (111) end face, and be provided with at least one buckling part (113) in holding part (111) end face appropriate location, and buckling part (113) is a crozier, and holding part (111) inner edge is provided with several ribs (114).
Iron ring (2) with magnetic (21) is arranged in the holding part (111), and iron ring (2) has a penetration hole (22), and an ora terminalis of this penetration hole (22) has a blocked part (23), and has a groove (24) between magnetic (21) and blocked part (23).
This flabellum wheel hub is gone up use in order to be arranged at a framework (3), and the centre of framework (3) has a bearing part (31), has the axle sleeve (32) that axostylus axostyle (13) plugs on the bearing part (31), and the outer cover of axle sleeve (32) is provided with a circuit board (33), drum (36) on drum (34), the coil groups (35) and once, and make the interior magnetic (21) of iron ring (2) be sheathed on down the outside of drum (34), coil groups (35) and last drum (36), form a fan.When iron ring (2) is desired to be arranged in the holding part (111), an ora terminalis that iron ring (2) is had a blocked part (23) is inserted after corresponding to holding part (111), make wheel hub (11) utilize the blocked part (23) of block (112) backstop iron ring (2) one ora terminalis, and iron ring (2) is positioned in the holding part (111) of wheel hub (11) with predetermined height.Wheel hub (11) can be fastened on groove (24) by buckling part (113), and utilize several ribs (114) to make the outer rim of iron ring (2) and the inner edge of wheel hub (11) increase frictional force, so, can make iron ring (2) stably fastening in holding part (111), so as to preventing that iron ring (2) and wheel hub (11) from getting loose, and reach the effect that is easy to assemble.Wheel hub (11) also can be chosen any one kind of them from axial flow (axial type) flabellum wheel hub, centrifugal (radial type) flabellum wheel hub, diagonal flow type (mixed flow type) flabellum wheel hub and cross-flow type (cross-flow type) flabellum wheel hub in addition.
In sum, the structure of this flabellum wheel hub can make overall structure firm, is difficult for getting loose, and reaches the effect that is easy to assemble.
