Abstract
The utility model relates to a fan blade wheel of an electric tool, in particular to a composite structured fan blade wheel of the electric tool. The fan blade wheel comprises a wheel base part and a fan blade part in structure, both the wheel base part and the fan blade part are formed in one piece by plastic injection, and a round sheet is inserted into the middle of the wheel base part. The utility model has the advantages that: the fan blade adopting the composite structure has the rigidity of metal material and low price; the weight of the fan blade wheel itself is also added, and the eccentric balance weight can be effectively realized; and the increasing of deadweight of the composite structured fan blade wheel can be selected as required, thereby meeting the requirements of various eccentric electric tools.
Description
Technical field
The utility model relates to a kind of fan blade of electric tool, especially relates to a kind of composite construction fan blade of electric tool.
Background technology
At present, the fan blade that uses in electric tool adopts plastic material or aluminum alloy material to make usually.Wherein the fan blade of plastic material owing to its poor rigidity, very easily deforms in the motor high speed rotating; Especially the deadweight of plastic blade wheel is light partially, can't realize having the counterweight needs of the instrument of eccentric structure requirement.Though and the fan blade good rigidly of aluminum alloy material and has certain weight, it is applicable to the counterweight of general eccentric structure instrument, and is not suitable for the counterweight needs of the bigger instrument of offset.In addition, because the price comparison height of aluminum alloy materials also can increase the cost of making fan blade accordingly.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that fan blade exists in the existing electric tool, and provide a kind of fan blade of composite construction, this fan blade not only has the rigidity of metal material, and deadweight can be selected to increase as required, make its counterweight needs that are easy to realize have the instrument of eccentric structure requirement, and cheap.
For solving the problems of the technologies described above, technical solutions of the utility model are to realize like this, a kind of fan blade of electric tool composite construction, comprise wheel base section 1 and fan blade part 2, described base section 1 and the fan blade part 2 of taking turns is by plastic injection-moulded one-shot forming, and it is characterized in that: described centre of taking turns base section 1 is embedded with circular sheet 3.
Described circular sheet 3 is provided with three apertures 4, and aperture 4 all equates with respect to the distance in the center of circle, and is the equilateral triangle distribution.
On the described circular sheet 3, therein on the connecting line in the aperture and the center of circle, and be provided with counterweight hole 5 in an opposite side of this aperture.
Described circular sheet 3 is a metal material.
Above-mentioned metal material can be iron.
Above-mentioned metal material can be kirsite.
Described circular sheet 3 is the bakelite material.
The beneficial effects of the utility model owing to adopt the fan blade of composite construction, make its rigidity that not only has metal material, and cheap advantage; And increased the own wt of fan blade, can satisfy the needs of electric tool eccentrically mounted weight effectively; And the recruitment of the deadweight of the fan blade of this composite construction can be selected as required, thereby can satisfy the needs of various eccentric electric tools.
Description of drawings
Fig. 1: be the structural representation of aluminium alloy fan blade in the prior art;
Fig. 2: be the structure cutaway view of Fig. 1;
Fig. 3: be the structural representation of the utility model composite construction fan blade;
Fig. 4: be the utility model composite construction fan blade structural representation on the other hand;
Fig. 5: be the structure cutaway view of the utility model composite construction fan blade;
Fig. 6: be the structural representation of the utility model circular sheet.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described:
Above-mentioned circular sheet 3 also can adopt the bakelite material, perhaps other metal material, and for example kirsite is selected accordingly according to instructions for use and processing request.
Because the thickness of circular sheet can be selected as required, the increase of the deadweight of the fan blade of described this composite construction can be selected as required, also can adjust the size in counterweight hole 5 according to the size of offset, a plurality of counterweights hole perhaps is set, thereby can satisfies the needs of various eccentric electric tool counterweights.
Above-mentioned eccentrically mounted weight also is applicable to shuttle electric tool.
