Figure.Fan wheel structure 10 of the invention is, for example, centrifugal impeller, including a wheel hub 11 and plural flabellum 12 and a lid as shown in the figure
Body 13.Wheel hub 11 has a top surface 111, which is equipped with the side wall 112 protruded out upward from top surface 111, the side wall 112
The top surface 111 for being circumferentially positioned at the outer rim of the top surface 111 and protruding out the prominent wheel hub 11 in end 1121 with one, and the side wall
112 have a plural slot 113, and the setting of the grade slots 113 interval simultaneously protrudes out 1,121 one interface 1131(of formation of end such as at this respectively
Fig. 2A), which has an inside 1127 towards 1128 opposite insides of the outside a center A of the wheel hub 11 and one
1127, and an accommodating space 114 is defined in the inside 1127 of the side wall 112 and on the top surface 111.
The equal flabellums 12 are circular combined with the side wall 112, and especially as shown in Figure 2 A and 2 B, each flabellum 12 has one
The slot 113 of the corresponding wheel hub 11 in plug division 121, is then axially inserted into the slot 113 from the interface 1131.The plug division
121 protrude out the inside that a binding end 122 is located at the side wall 112 radially towards the center of the wheel hub 11 along the one of the wheel hub 11
In 1127 accommodating space 114, which has one to combine recess 1221 on the top surface of the wheel hub 11 111, in the knot
The two sides for closing recess 1221 are formed with two buckle arms 1223, and the center A of the plug division 121 towards the opposite wheel hub 11 has protruded out one freely
End 123.Since the plug division 121 is extended with the binding end 122 in the inside of side wall 112 1127, the then free end of extension
123 outside the outside of the side wall 112 1128, therefore the plug division 121 is located between the binding end 122 and the free end 123.
The lid 13 is located at the accommodating space of the inside 1127 of the side wall 112 combined with the top surface 111 of the wheel hub 11
In 114, which is that annular lid has a central open-work 131 and plural engagement groove 132 and docking side 137(such as Fig. 3 A
It is shown) top surface 111 for combining the wheel hub 11 is corresponded to, especially as shown in Fig. 3 A and Fig. 3 B, a fixing is equipped in each engagement groove 132
Element 133 cooperates this to wait the combination recess 1221 of flabellums 12, wherein combination of the equal engagement grooves 132 respectively in connection with the equal flabellums 12
End 122, and the fixing element 133 in the engagement groove 132 is enabled to buckle into this in conjunction with recess 1221 to fix the grade flabellums 12, and tying
The buckle arm 1223 for closing 1221 two sides of recess buckles into this in conjunction with clamp fixing element of taking advantage of a situation after recess 1221 in the fixing element 133
133, keep the binding end 122 of the flabellum 12 more firm combined with the lid 13, prevent flabellum 12 because wheel hub 11 operating by
Centrifugal force is acted on and is thrown out of.
The material of the above-mentioned flabellum 12 of the present invention is made of metal using punching press, and the thickness of flabellum 12 is preferably less than
The ultrathin flabellum of 0.15mm, and the material of the wheel hub 11 and lid 13 may be selected to be plastic cement and is made using ejection formation.
It is multiple referring to Figure 1A and Fig. 3 A, the top surface 111 of the wheel hub 11 is equipped with plural number recess by such as pillar of fitting 116 or convex
Grain, grade recess are arranged at intervals at the inside 1127 of the side wall 112 (as shown in Figure 1A) by fitting 116, the lid 13
The top surface 111 of the corresponding wheel hub in docking side 137 be equipped with the plural number protrusion such as shrinkage pool of connector 136 and cooperate the recess by fitting
116.Especially as shown in Fig. 4 A, Fig. 4 B and Fig. 4 C, the recess is inserted through after by fitting 116 by the protrusion connector 136, thoroughly
That crosses that rivet hot processing procedure makes grade protrusion connector 163 forms a fixing head through end, the diameter of the fixing head be greater than the recess by
The internal diameter (as shown in Figure 4 C) of fitting 116, so that the lid 13 is fixed on the top surface 111 of the wheel hub 11, while the flabellum 12
Binding end 122 is combined closely in engagement groove 132, this combines recess 1121 and two buckle arms 1223 closely to detain the solid fixing element
133(is as shown in Figure 4 B).
Rivet hot processing procedure above-mentioned is a kind of two stage processing procedure.It is first stage, lid 13 and flabellum 12 and wheel hub 11 is pre-
Group is simultaneously put to board, the protrusion connector 136 of lid 13 is directly blowed to using hot wind, hot blast temperature is according to the plastic cement for making the lid 11
Depending on the plasticization temperature of material.Second stage is pressed on protrusion connector 136 under the cold riveting stake using a tool molding capitiform,
Execute riveted molding make the protrusion connector 163 through end formed a fixing head, it is then cooling while complete lid 13 with
The combination of wheel hub 11.
However, it is not limited to this, implement in another substitution, mold will be put into after flabellum 12 and the wheel hub 11 combination in advance and worked as
In, then directly the lid 13 is formed on the top surface 111 of wheel hub 11 and combined with flabellum 12 using injection molding method
End 122 combines.In addition, implementing in another substitution, the lid 13 and wheel hub 11 open up corresponding open-work respectively, then by plastic cement material
The rivet of matter or metal material is inserted into the open-work of lid 13 and wheel hub 11, so that the two combines.
Furthermore the present invention does not limit to above-mentioned implementation, implement in another substitution, as shown in figure 5, the side wall of wheel hub above-mentioned 11
112 can also omit, therefore the binding end 122 of the flabellum 12 is in advance combined with the engagement groove 132 of lid 13, and then surround and put
It penetrates shape to be arranged in around lid 13, then the docking side 137 of lid 13 is again combined with the top surface 111 of the wheel hub 11, so that should
Equal flabellums 12 are fixed on the top surface 111 of the wheel hub 11, and towards 11 outside radiated entend of wheel hub.
By above-mentioned, the present invention has a binding end along the radial projection of the wheel hub 11 by the plug division 121 of flabellum 12
122 in the accommodating space 114, and via lid 13 combined with the wheel hub 11, so that flabellum 12 must be fixed on around wheel hub, with
Enhance bond strength between flabellum 12 and wheel hub 11, improves known flabellum and wheel hub directly welds or is clamped connection and causes junction
The problem of being easily broken off, and improve the problem that known wheel hub load-carrying unevenness is caused using solder joints.
Only as described above, the only preferably feasible embodiment of the present invention, such as using the above-mentioned method of the present invention,
Shape, construction, device change for it, should all be contained in the interest field of this case.
