Embodiment
Also in conjunction with the embodiments the utility model is elaborated below with reference to accompanying drawing.Need to prove, under the situation of not conflicting, below feature among each embodiment and the embodiment can make up mutually.
Figure 1 shows that the structural representation of the fan blade 10 of the electric fan among one of them embodiment of the utility model, fan blade 10 comprises wheel hub 12 and is arranged at some blades 11 that 12 weeks of this wheel hub make progress, the wheel hub 12 of described fan blade 10 is provided with first joint, and this first joint cooperates with second joint on the rear net cover 20.During packing, described fan blade 10 removably is connected with described rear net cover 20 with described second joint by described first joint.
Described first joint in the present embodiment comprises at least two buckles 14.Preferably, described wheel hub 12 is the cylinder-like structure of an end opening, the center of described wheel hub 12 has the locating column 13 that is connected with machine shaft, and described buckle 14 molding and forming are in the inboard of described wheel hub 12, and the head 141 of described buckle 14 is stretched from the opening end of described wheel hub 12.As required, the quantity of described buckle 14 can be 2 to 4.Preferably, all described buckles 14 are along the circumferential direction evenly arranged centered by the shaft axis of described wheel hub 12.Preferably, described buckle 14 is cylindric connecing, and the diameter of described buckle 14 heads 141 is greater than the diameter of remaining part.Preferably, the head 141 of described buckle 14 is provided with in-line groove 142, makes its easily extruding contraction of head 141, makes things convenient for its insertion and extracts hole clipping 212.
