Description
Technical field
The utility model relates to a kind of centrifugal wind wheel, and in particular to a kind of centrifugal wind wheel, is the wind wheel for exhausting.
Background technology
At present, wind wheel is widely used in various fields.
Wherein, a kind of centrifugal wind wheel is made of the first leaf dish, the second leaf dish, blade；Each blade sequential is into annulus
Shape, the annulus and leaf dish are coaxial, and the lower end of blade is connected in the first leaf dish, and the upper end of blade is connected in the second leaf dish.Should
Kind centrifugal wind wheel weight weight, it is complicated.
Utility model content
The utility model technical issues that need to address are to provide a kind of centrifugal wind wheel, the structure letter of this kind of centrifugal wind wheel
Single, assembling is easy.
The utility model centrifugal wind wheel can adopt the following technical scheme that:
A kind of centrifugal wind wheel, including leaf dish, multiple blades, each blade sequential connect into circular ring shape, the lower end of blade
Connect and be fixed in leaf dish；The upper end of each blade is equipped with bending part, first connecting portion, and bending part is equipped with second connecting portion；Each leaf
The second connecting portion of piece is connected with the first connecting portion of a upper blade, second connecting portion and the first leaf of last blade
The first connecting portion connection of piece.
The utility model solves the problems, such as further take following measures：
One of mode is：The first connecting portion is connecting hole, and second connecting portion is clinch.
One of mode is：The connection with connecting hole is realized in bending after clinch is stretched into connecting hole.
One of mode is：The connecting hole is arranged at bending part.
One of mode is：The clinch is pre-large post-small, and the connecting hole is matched with the size shape of clinch.
One of mode is：The lower end of blade is equipped with extension, and extension is put in the corresponding hole of leaf dish, real after bending
Now connection is fixed.
One of mode is：Into an angle of 90 degrees between bending part and blade body.
One of mode is：The second connecting portion is connecting hole, and first connecting portion is clinch.
Above-mentioned technical proposal has such technique effect:
1st, the utility model assembling is simple.
2nd, the big production of the utility model modernization easy to implement.
3rd, the utility model formed precision is high, and the uniformity after blade assembling is good, and the precision of dress is high, good dynamic balance.
4th, the noise of the utility model is low, and air quantity is big.

Embodiment
The utility model is specifically described with reference to specific embodiment.
Embodiment 1：As shown in Figures 1 to 8, a kind of centrifugal wind wheel, including leaf dish 1, multiple blades 2, each blade is sequentially
Circular ring shape is arranged in, the lower end of blade 2 is connected and fixed in leaf dish；The upper end of each blade is equipped with bending part 3, first connecting portion
21, bending part 3 is equipped with second connecting portion 31；The second connecting portion 31 of each blade and the first connecting portion 21 of a upper blade connect
Connect that (in such as Fig. 5, blade 201 is a blade, upper blade when blade 202 is according to arrangement.The of a last blade
Two connecting portions are connected with the first connecting portion of first blade.
Each blade upper end of the utility model is by being connected with each other, i.e., the second connecting portion of each blade and a upper blade
First connecting portion connects, and the second connecting portion of last blade is connected with the first connecting portion of first blade.It can make
End, which is mutually enclosed, is combined into an annular shape.Interlobate mutual alignment, structure is set more to stablize, firmly.
In this example, the first connecting portion 21 is connecting hole, and second connecting portion 31 is clinch.
The connection with connecting hole is realized in bending after clinch is stretched into connecting hole.So assembling is simple, and producing efficiency is high.
The connecting hole is arranged at bending part.
The clinch is pre-large post-small, and the connecting hole is matched with the size shape of clinch.In this example, clinch is
Inverted trapezoidal (surface size is pre-large post-small).After clinch bending, since its is pre-large post-small, clinch will be mutual with connecting hole
Clamping.
The lower end of blade 2 is equipped with extension 22, and extension 22 is put in the corresponding hole 101 of leaf dish 1, and connection is realized after bending
It is fixed.It is easy to connect, simply.
A kind of improved procedure is：Into an angle of 90 degrees between 2 main body of bending part 3 and blade.Can certainly be other angles.
Another way is：Second connecting portion can be connecting hole, and first connecting portion can be clinch.
In addition, certainly, blade can be designed to other shapes according to design requirement.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
