Abstract
The utility model provides a blade of a fan, and belongs to the technical field of machinery. By the aid of the blade, technical problems of loud noise, heavy weight, high cost and the like of an existing blade of a fan can be solved. The blade of the fan comprises an inner blade body made of metal materials. An outer blade body fixedly wraps the outside of the inner blade body, the area of the outer blade body is larger than that of the inner blade body, and the outer blade body is made of nonmetal materials. The blade of the fan has the advantages of light weight, low cost and noise, and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to the blade of a kind of blade, particularly a kind of blower fan.
Background technique
Blower fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and blade is the important component part of blower fan.Existing blade is all generally single layer structure, comprises a lamellar body, and this lamellar body adopts ferrous material to make, and lamellar body one end offers for connecting the fixed hole of motor; The shortcomings such as such blade exists noise larger, and weight is heavier, and cost is higher.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of blade of blower fan, and this blade has little, the lower-cost feature of noise.
The purpose of this utility model can realize by following technical proposal: a kind of blade of blower fan, comprise the interior lamellar body that adopts metallic material to make, it is characterized in that, described interior lamellar body outer wrapping is fixed with outer lamellar body, the area of described outer lamellar body is greater than the area of described interior lamellar body, and described outer lamellar body adopts nonmetallic material to make.
In the blade of above-mentioned blower fan, described interior lamellar body adopts ferrous material to make, and described outer lamellar body adopts plastic materials to make.
In the blade of above-mentioned blower fan, described outer lamellar body by cast mode be wrapped on interior external.
In the blade of above-mentioned blower fan, on described outer lamellar body, offer some bloops.
In the blade of above-mentioned blower fan, on described outer lamellar body, there are some outwardly reinforcing parts, described reinforcing part is strip.
In the blade of above-mentioned blower fan, on described outer lamellar body, offer outer fixed hole, on described interior lamellar body, offer interior fixed hole, described outer fixed hole and interior fixed hole connect mutually.
Compared with prior art, the utlity model has following advantage:
1, by by the area of lamellar body in reducing, can effectively reduce weight, plastic materials is compared ferrous material, and price is more cheap.
2, by adopting the outer lamellar body that plastic materials makes and offering bloop on lamellar body outside, can effectively reduce the noise that blower fan produced at work.
3, on outer lamellar body, there are some outwardly reinforcing parts, can improve the intensity of outer lamellar body, improve working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
In figure, 1, interior lamellar body; 2, outer lamellar body; 3, bloop; 4, reinforcing part; 5, outer fixed hole; 6, interior fixed hole.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, a blade for blower fan, comprises the interior lamellar body 1 that adopts metallic material to make, and described interior lamellar body 1 outer wrapping is fixed with outer lamellar body 2, the area of described outer lamellar body 2 is greater than the area of described interior lamellar body 1, and described outer lamellar body 2 adopts nonmetallic material to make.
In the present embodiment, described interior lamellar body 1 adopts ferrous material to make, and described outer lamellar body 2 adopts plastic materials to make.Described outer lamellar body 2 is wrapped on outside interior lamellar body 1 by the mode of cast.On described outer lamellar body 2, offer some bloops 3.
In the blade of above-mentioned blower fan, on described outer lamellar body 2, there are some outwardly reinforcing parts 4, described reinforcing part 4 is strip.
In the blade of above-mentioned blower fan, on described outer lamellar body 2, offer outer fixed hole 5, on described interior lamellar body 1, offer interior fixed hole 6, described outer fixed hole 5 and interior fixed hole 6 connect mutually.By outer fixed hole 5 and interior fixed hole 6, this blade can convenient be connected with the output shaft of motor.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used 1 herein, interior lamellar body; 2, outer lamellar body; 3, bloop; 4, reinforcing part; 5, outer fixed hole; 6, the term such as interior fixed hole, but do not get rid of the possibility of using other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
