The invention provides an unmanned aerial vehicle rotor wing connecting structure which comprises a guide pipe, a guide rod is arranged in the guide pipe, the top end of the guide pipe extends inwards to form a first turned edge, the inner end of the guide rod extends outwards to form a second turned edge, a spring is arranged between the first turned edge and the second turned edge, pressing pieces are fixedly arranged at the outer end of the guide rod, supporting pieces extend outwards from the side wall of the guide pipe, an unmanned aerial vehicle rotor wing comprises at least two blades, connecting holes are formed in the ends of the blades, the supporting pieces extend upwards to form rotating shafts, the rotating shafts penetrate through the connecting holes, and when the guide rod moves into the guide pipe to the limit position, the supporting pieces and the pressing pieces can clamp the ends of the blades. The pressing pieces and the supporting pieces are matched to clamp the blades, the blades are prevented from deviating in the speed reduction process, the guide rod capable of moving in the vertical direction matches the guide pipe, after the unmanned aerial vehicle takes off, the pressing pieces and the supporting pieces are separated from each other, the connecting positions of the blades are loosened, and therefore, the blades are affected by centrifugal force to move outwards to limit positions.

    本发明提供了一种无人机旋翼连接结构,包括导向管,其内置有导向杆,且导向管顶端向内延伸出第一翻边,导向杆内端向外延伸出第二翻边,第一翻边和第二翻边之间置有弹簧,导向杆外端固设有压片,导向管侧壁向外延伸出支撑片,无人机旋翼包括至少两片桨叶,桨叶端部开有连接孔,支撑片向上延伸出转轴,转轴穿过连接孔,当导向杆向导向管内运动至极限位置时,支撑片和压片能夹紧桨叶端部。本发明采用压片和支撑片相配合夹紧桨叶,防止桨叶在减速过程中发生偏移,采用能沿竖直方向运动的导向杆和导向管相配合,使得在无人机起飞之后,压片和支撑片相互分离,使得桨叶连接处被放松,以便于桨叶受离心力影响向外运动至极限位置。
