Background technology
At present, domestic unmanned air vehicle technique quickly grows, and propeller aero (unmanned vehicle and manned vehicle) is more next
More comes into the life of people；
The propeller of the most aircraft in present market is locked by using nut, nut or screw fashion
Mode install；
The mode that just indivedual Quick Release in the market are installed, is all by reinstalling an adaptor on motor
(another part), could realize changing blade and fast assembling-disassembling in the mode using metal buckle；Or by electricity
Processing groove position on machine shaft, locking is completed using the mode of ball or roller bearing during pushing；But this connection side
Speed is slow when formula is dismounted, disassembly efficiency is low, high cost when high cost, processing during assembling.The processing technology of motor shaft is complicated, processing
High cost；
In the traditional drawback of technology now on the market：
Use the mode of the mode (the snap component structure being made up of metal clips etc.) of the outer pipe fitting on motor；Gold
The elastic force for belonging to shell fragment can be when dismantling often, and when awing speed speed switches aircraft, shell fragment can't lock blade, hold
Easily there are the danger of propeller disengaging, the case that come off row, and ratio is higher；
Using the processing groove position on motor shaft, the mode for being inserted into groove internal locking, the processing of axle draw-in groove are slided with ball or roller bearing
Precision does not reach ball or roller bearing slips into rear completely good tight fit (similar with tracheae switch Quick Release insertion joint herein), when
In flight course medium velocity low switching high, propeller is left and right rocking back and forth to aircraft；The vibrations that cause aircraft are big,
The electric current of motor operation is big, reduces the aircraft flight time, and aircraft shooting effect is impacted；Multiple rocks meeting back and forth
Draw-in groove clamping effect is damaged, is ultimately resulted in out of danger；
And market prior art appeal several ways, the difficulty in assembling is big, easily assemble it is bad, when assembling bad
Time will bring the risk of de- oar to structure；Vibrations will be in the running caused when assembling bad, influence is brought to aircraft；
Mode complexity on Product processing, cost are high, increase the cost pressure of aircraft product.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1-6 are referred to, in the embodiment of the present invention, a kind of fast assembling disassembling structure of blade, including propeller blade 5, spiral
The structure of blade 5 is not limited to two leaf oars, three leaf oars or four leaf oars, and propeller blade 5 is fixedly connected on the both sides of propeller fixed cover 4
Face, spinner 8 is provided with the top of propeller fixed cover 4, and propeller blade 5 is made of PC, and spinner 8 is made of PC or aluminium,
Spiral spinner locking barb 41 is provided with propeller fixed cover 4, spiral spinner 8 is buckled in spiral shell on spiral spinner locking barb 41
Rotation spinner locking barb 41 is buckled on spinner 8, and the inside of propeller fixed cover 4 is provided with sliding block 7, and sliding block 7 uses aluminium, copper material
Or plastic rubber shaping, spring 6 is installed between sliding block 7 and spinner 8, spring 6 is made of spring steel, the two ends difference of spring 6
With sliding block 7 and the elastic connection of spinner 8, the bottom of propeller fixed cover 4 is provided with propeller lock draw-in groove 42, propeller fixed cover
4 are enclosed within skull projecting shaft 2, and the circular diameter structure on skull projecting shaft 2 ensure that the concentricity that Quick Release blade is installed with motor,
Make propeller blade 5 that the influence of concentricity will not be subject to cause rotation to shake when rotated, the top on skull projecting shaft 2 is fixed
Four leaf slot structures 3 are provided with, propeller lock draw-in groove 42 is stuck in the leaf slot structure 3 of skull projecting shaft four and is adapted to, and skull stretches out
Propeller lock draw-in groove 42 on axle 2 cooperates with the leaf slot structure 3 of skull four of propeller fixed cover 4, and limitation propeller is left
The free activity space of right horizontal direction, does not result in what the double swerve of propeller blade 5 in the rotation status that work was caused completely
Depart from risk；With rock the vibrations that are brought to aircraft, influence aircraft performance, skull projecting shaft 2 to be arranged on skull 1, head
Lid 1 is processed using aluminium or copper material, and a four leaf groove shapes are processed as (including but not limited to by by skull projecting shaft 2
Four leaves, comprising bilobed structure to many impeller structures)；Propeller is processed as one with quick-disassembly structure, by built-in sliding block 7,
Spring 6 is installed on sliding block 7, spinner 8 is installed on spring 6, spinner 8 uses the embedded cooperation of draw-in groove, oar with propeller fixed cover 4
The overhead structure of cap 8 and the embedded locking of propeller fixed cover 4, will spinner 8 it is independent, color can be individually done, in forward-reverse spiral
Can be processed using different colours on oar and distinguished, it is to avoid forward-reverse spiral oar setup error.
The fast assembling disassembling structure of this blade, fill oar when pressed down by by propeller fixed cover 4, spring 6 shrinks, sliding block
7 slide up, and propeller lock draw-in groove 42 sinks to the leaf slot structure 3 of skull four of skull projecting shaft 2, then by the He of propeller fixed cover 4
The horizontal direction of propeller blade 5 turns clockwise after 45 degree, decontrols propeller fixed cover 4 and propeller blade 5, the elastic force sliding block 7 of spring 6
Push, withstand the plane of skull projecting shaft 2, now propeller is assembled；When oar is torn open by propeller fixed cover 4 and propeller blade 5
Press down, spring 6 shrinks, sliding block 7 slides up, then by propeller fixed cover 4 and the horizontal direction rotate counterclockwise 45 of propeller blade 5
After degree, propeller fixed cover 4 and propeller blade 5 are decontroled, now propeller is torn oar open and finished.
In sum：The fast assembling disassembling structure of this blade, simplifies the difficulty of processing of quick-disassembly structure, you can simply processing
The processing of quick-disassembly structure can be just completed under operation, processing cost is greatly reduced, the present invention is done in aircraft cost control
Go out contribution；Assembling difficulty is low, and structural strength reliability is even more while rapid-assembling/disassembling blade effect is reached and perfectly ensure that spiral shell
Rotation oar departs from and propeller loosens the risk caused to aircraft.
