Embodiment
Below in conjunction with each mode of execution shown in the drawings, the utility model is elaborated; but should be noted that; these mode of executions are not limitation of the utility model; those of ordinary skills are according to these mode of execution institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection domain of the present utility model.
In addition, it should be noted that, in order to narrate conveniently, in following each accompanying drawing, use identical label and represented different structures, although same label is reused, in each accompanying drawing, each label is different and independently, therefore, the implication of each label is clearly, determines.
Angle of fan leaves controlling device 100 of the present utility model is for blade and the wheel hub of connecting fan, and can regulate the setting angle of blade.The wheel hub joint 20 that angle of fan leaves controlling device 100 comprises blade joint 10 and is arranged at described blade joint 10 1 sides, described blade joint 10 comprises that, along the evenly distributed projection 101 of all sides, described wheel hub joint 20 comprises lug boss 201 or the depressed part 202 matching with wheel hub.Wherein, when described wheel hub joint 20 comprises lug boss 201, on described wheel hub, be formed with the connecting groove matching with this lug boss 201; When described wheel hub joint 20 comprises depressed part 202, on described wheel hub, be formed with the plug connector matching with this depressed part 202.
As shown in Figure 1, particularly, described blade joint 10 is regular polygon, and described protruding 101 is correspondingly each side of regular polygon.Thereby in present embodiment, on blade, respective recesses is formed with the structure matching with described polygonal blade joint 10.Due to symmetrical in regular polygon structure, thereby each summit on it is positioned in a circular trace, and this circular trace is evenly divided.Thereby the quantity of establishing summit is N, thus 360 °/N of an adjustable vane angle value each time.
As shown in Figure 2, as a kind of alternative real-time mode, described blade joint 10 comprises discoidal the first noumenon 101 and the engaging tooth 102 that is arranged at 101 weeks sides of described the first noumenon.Thereby blade joint 10 is a gear shape substantially.Correspondingly, on blade, be formed with the structure matching with described polygonal blade joint 10.Because described each engaging tooth 102 is uniformly distributed in all sides of discoidal the first noumenon 101, thereby the quantity of establishing summit is M, thus 360 °/M of an adjustable vane angle value each time.
As shown in Figure 3, further, described wheel hub joint 20 comprises discoidal the second body 201 and is arranged at the bar shaped convex tendon 202 on described the second body 201.Correspondingly, be formed with the structure matching with this projection 202 on wheel hub, convex tendon 202 is plugged in this wheel hub.
