Middle A-A sectional views；Fig. 4 is the I portions mplifying structure schematic diagram of Fig. 2；Fig. 5 is that structure is shown when screw described in the utility model draws in
It is intended to.
Specific embodiment
Foldable propeller described in the utility model, including rotating shaft 1, arrange slip ring 2 in rotating shaft 1, slip ring 2 can
Move axially along rotating shaft 1, the top of rotating shaft 1 is fixedly connected with tupelo 10, spring 6, bullet are set between tupelo 10 and slip ring 2
Spring 6 is looped around in rotating shaft 1, and the border of slip ring 2 is uniformly arranged several first contiguous blocks 4, and the border of tupelo 10 arranges several cards
Groove 16, the quantity of draw-in groove 16 is identical with the quantity of the first contiguous block 4, and blade pedestal axle 14, blade pedestal axle are installed in draw-in groove 16
Be hinged with one end of blade pedestal 7 on 14, blade pedestal 7 can around the axial-rotation of blade pedestal axle 14, each blade pedestal 7
The other end is hinged respectively by connecting rod 3 with each first contiguous block 4, and on each blade pedestal 7 blade 5 has been fixedly connected with.This practicality
In new when screw does not work, slip ring 2 is located remotely from the position of tupelo 10 under the elastic force effect of spring 6, slides
Ring 2 draws the position that each blade 5 keeps parallel with rotating shaft 1 by connecting rod 3, in rounding state, is easy to carrying or the fortune of aircraft
It is defeated, it is to avoid blade caused damage in carrying or transportation.When screw needs work, rotating shaft 1 drives blade 5 to rotate,
As shown in figure 1, the Automatic-expanding under the action of the centrifugal of blade 5, makes slip ring 2 overcome on the elastic force of spring 6 and moves, the end of blade 5
It is stuck in draw-in groove 16, you can normal work, the shape of draw-in groove 16 can be made into the shape with the matching ends of blade 5, be conducive to
Blade keeps shape when rotating at a high speed, will not twist.Propeller works whole process is complete by need not manually being operated
Automatic-expanding and folding into blade.After screw stops operating, each blade 5 draws in automatically in the presence of spring force, keeps away
Exempt from aircraft landing rear screw shaft to collide with the barrier of Near Ground and be damaged.
The utility model can adopt following structure for the ease of assembly and disassembly blade：The tupelo of the both sides of each draw-in groove 16
10 top surfaces open up groove 8, and each two ends of blade pedestal axle 14 are installed in the groove 8 of the both sides of draw-in groove 16, blade pedestal axle 14
Be respectively provided with briquetting 15 in the groove 8 at two ends, each briquetting 15 respectively with 14 liang of end in contact of blade pedestal axle, the top of tupelo 10 is installed
Axle cap head 9, axle cap head 9 is connected by screw thread with tupelo 10, and the bottom surface of axle cap head 9 contacts with blade pedestal axle 14.Certain need to be changed
During one blade 5, axle cap head 9 can be separated with tupelo 10, the corresponding blade pedestal axle 14 of the blade 5 is taken out from groove 8
Blade 5 can be removed.The structure can be changed easily when a certain blade is impaired, and be not required to change a whole set of spiral
Oar.
The utility model is in order to mitigate the weight of screw itself, while flight resistance is reduced, can be in described axle cap head 9
Top arranges axial passage 12, and tupelo 10 and the middle part of rotating shaft 1 arrange cavity 20, and cavity 20 is communicated with axial passage 12,
The side wall of rotating shaft 1 of the border of cavity 20 opens up lateral passage 11, and lateral passage 11 is communicated with cavity 20.During aircraft flight,
The air resistance in aircraft moving process can be advantageously reduced by air-flow between axial passage 12 and lateral passage 11
Power, reduces air-flow to being in fashion the impact of circuit.
The utility model in order to when preventing revolution speed of propeller too fast slip ring 2 rotate relative to rotating shaft 1, cause 3, each connecting rod
Raw distortion causes blade stuck, can be oriented to groove 13 by axially disposed slip ring in described rotating shaft 1, and slip ring is oriented to groove
Guide pad 17 is set in 13, and guide pad 17 is connected with slip ring 2.When rotating shaft 1 is rotated, slip ring 2 is rotated with guide pad 17.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model.This practicality is new
