如图12所示，连接柱62插设于卡套42内、并且多个卡扣64分别容置于各通槽43内，通过向低限位筋44方向旋转连接柱62使卡扣64经过低限位筋44进入卡槽45内，实现卡套42与卡扣结构6的卡接，如图13所示。通过低限位筋44和高限位筋46可实
现螺旋桨组件防呆，防止装错螺旋桨组件100。As shown in FIG. 12, the connecting post 62 is inserted into the ferrule 42 and the plurality of snaps 64 are respectively received in the through slots 43, and the buckle 64 is rotated by rotating the connecting post 62 toward the lower limit rib 44. The lower limit rib 44 enters the card slot 45 to realize the engagement of the ferrule 42 and the buckle structure 6, as shown in FIG. Through the low limit rib 44 and the high limit rib 46
The propeller assembly is now foolproof and prevents the wrong propeller assembly 100 from being installed.
本发明的一实施例中，螺旋桨下支架4上有三个通槽43和三个卡槽45，卡扣结构6上相应的设有三个卡扣64。In one embodiment of the present invention, the propeller lower bracket 4 has three through slots 43 and three slots 45, and the buckle structure 6 is correspondingly provided with three buckles 64.
螺旋桨组件100与旋转驱动组件200之间的快拆是通过螺旋桨下支架4和卡扣结构6之间的配合完成的，螺旋桨下支架4和卡扣结构6之间的配合过程是：The quick release between the propeller assembly 100 and the rotary drive assembly 200 is accomplished by the cooperation between the propeller lower bracket 4 and the snap structure 6, and the cooperation between the propeller lower bracket 4 and the snap structure 6 is:
为了方便说明，去除了第一桨叶1、第二桨叶3及螺旋桨上支架2，将螺旋桨下支架4从上往下套入卡扣结构6上，螺旋桨下支架4上的通槽43允许卡扣结构6上的卡扣64通过，将螺旋桨下支架4按到底，螺旋桨下支架4的通槽43的两侧有一个低限位筋44和一个高限位筋46，如图12所示。当螺旋桨下支架4按到底后，因通槽43一侧的高限位筋46限制，使螺旋桨下支架4只能朝一个方向旋转，卡扣结构6只能朝另一方向旋转。因通槽43一侧的高限位筋46阻挡卡扣64，但卡扣64可以越过通槽43另一侧的低限位筋44，因此使卡扣结构6只能朝低限位筋44方向旋转。当螺旋桨下支架4旋转至卡扣结构6的卡扣64落入卡槽45内的位置时，卡槽45一侧的高限位筋46会阻止螺旋桨下支架4继续旋转，松开手，下面的弹簧7会将螺旋桨下支架4顶起，这样，卡扣结构6的卡扣64就会完全和螺旋桨下支架4的卡槽45配合，起到固定作用，完成螺旋桨组件100与旋转驱动组件200之间的装配，如图13所示。当需要拆下螺旋桨组件100时，则反过来重复刚才的动作，即按下螺旋桨组件100，反向旋转使卡扣结构6的卡扣64至螺旋桨下支架4上的通槽43的位置时，即可取下螺旋桨组件100。For convenience of explanation, the first blade 1, the second blade 3 and the propeller upper bracket 2 are removed, and the propeller lower bracket 4 is inserted into the buckle structure 6 from the top to the bottom, and the through slot 43 on the propeller lower bracket 4 allows The buckle 64 on the buckle structure 6 passes through, and the propeller lower bracket 4 is pressed to the bottom. The two sides of the through slot 43 of the propeller lower bracket 4 have a low limit rib 44 and a high limit rib 46, as shown in FIG. . When the lower propeller holder 4 is pushed to the bottom, the lower limit rib 46 on the side of the through groove 43 is restricted, so that the lower propeller holder 4 can only rotate in one direction, and the snap structure 6 can only rotate in the other direction. Since the high limit rib 46 on one side of the through groove 43 blocks the buckle 64, the buckle 64 can pass over the lower limit rib 44 on the other side of the through groove 43, so that the buckle structure 6 can only face the lower limit rib 44. Direction rotation. When the propeller lower bracket 4 is rotated to a position where the buckle 64 of the snap structure 6 falls into the slot 45, the high limit rib 46 on the side of the slot 45 prevents the propeller lower bracket 4 from continuing to rotate, releasing the hand, below The spring 7 will lift the propeller lower bracket 4, so that the buckle 64 of the buckle structure 6 will fully cooperate with the slot 45 of the propeller lower bracket 4 to fix the screw assembly 100 and the rotary drive assembly 200. The assembly between them is shown in Figure 13. When it is necessary to remove the propeller assembly 100, the previous action is reversed, that is, when the propeller assembly 100 is pressed, and the reverse rotation is performed to bring the buckle 64 of the snap structure 6 to the position of the through groove 43 on the propeller lower bracket 4. The propeller assembly 100 can be removed.
