Embodiment
As shown in figs 1 to 6, the aircraft propeller device of convenient disassembly described in the utility model, including motor 1,
Propeller 2, the propeller 2 includes blade 21 and blade axle sleeve 22, to make on propeller convenient disassembly, the motor 1
Covered provided with the fast disassembly type clamping that fast assembling-disassembling can be realized with blade axle sleeve 22 in 3, and clamping set 3 and be provided with spring 4.This practicality
It is new when in use, propeller 2 can directly by its blade axle sleeve 22 and clamping cover 3 adapting device and spring 4 to paddle shaft
It is installed on motor the holding out against effect of set 22 and fast demountable, therefore maintenance and changes extremely convenient, and by spiral
Oar 2 can be pulled down in transport from motor 1, to reduce its overall shared volume, so as to effectively reduce cost of transportation.For
Make the utility model structure simpler, reliable, an at least grab 221 is provided with above-mentioned blade axle sleeve 22, above-mentioned clamping set 3 includes
Sleeve 31 and at least one be integrally formed at the buckle structure for being available for the grab 221 to slide into locking in the sleeve 31, on
State spring 4 to be sleeved in the rotating shaft 11 of motor 1 for covering in 3 positioned at clamping, above-mentioned propeller 2 passes through the grab 221 and institute
State buckle structure cooperation clamping and the holding out against effect of above-mentioned spring 4 and realize and be reliably connected with clamping set 3.To be further
Strengthen its reliability of structure, above-mentioned buckle structure include upper rib 32 and on this side of rib 32 gear bone 33, and on
The Kou Chu that slides into for stating the opposite side formation of rib 32 is additionally provided with retaining flange 34.Above-mentioned blade axle sleeve 22 includes being coated at
State the outer sleeve body 222 on clamping set 3 and be integrally formed in outer sleeve body 222 and coordinate the internal axle sleeve being nested with motor rotating shaft
223, above-mentioned grab 221 is integrally formed at the periphery of internal axle sleeve 223.To strengthen its reliability of structure, typically above-mentioned interior
The periphery of axle sleeve 223 is provided with least two grabs 221, above-mentioned clamping set 3 and is correspondingly provided with least two buckle structures, adjacent two
Space between buckle structure forms chute.So, because clamping covers the retaining flange and gear that have on the inside of 3 by upper flange and both sides
Spring 4 is provided with again in the buckle structure with neck that bone is collectively constituted, clamping set 3, so when need to install propeller 2, first will
The blade axle sleeve 22 of propeller 2 be plugged in clamping set 3 on then under by, now internal axle sleeve of the spring 4 in blade axle sleeve 22 and
Top effect is lower under grab is shunk, then blade axle sleeve 22 is rotated forward into some angles, grab 221 is crossed below retaining flange
The neck that mouth enters in buckle structure is slided into, then hand decontrols the lower pressure to propeller 2, and the self-return of spring 4 is withstood upwards
The internal axle sleeve of blade axle sleeve, makes grab 221 be maintained inside neck.Neck makes grab be maintained at clamping set the inside, it is impossible to pull out
Come, gear bone 33 is used for the axial restraint of grab 21, it is kept the fixation with motor when rotated.Along with paddle shaft
The outer sleeve body of set encases clamping set, both adds fixing intensity（Intensity is more preferable）, aesthetic feeling is added again.Equally working as needs to remove spiral shell
When revolving oar 2, as long as pressing blade axle sleeve, its spring 4 is shunk, and blade axle sleeve is moved down, and is then inverted some angles, is made grab
221 can cross retaining flange by rotation, grab 221 is departed from neck.Let go again can make blade axle sleeve automatically exit from
The locking of clamping set, propeller can be removed from clamping set, so dismounting is extremely simple, conveniently.Wherein above-mentioned driving electricity
Machine 1 includes stator module 12 and rotor assembly 13, and above-mentioned clamping set 3 is connected on the rotor assembly 13, to make motor
Both there is good radiating effect, sand and soil can be prevented to enter motor internal, the stator module 12 and rotor set again
Anti-dust net 14,14 is respectively equipped with part 13.Each anti-dust net 14,14 is fixed by fixed support, can so use thin
Anti-dust net, existing radiating effect can prevent sand and soil from entering inside motor again.In addition can also be by radiating
The size shape limitation in hole, such as makes vane type shape by rotor, strengthens air flow, reach more preferable radiating effect, increase work(
Rate, improves motor performance.The utility model is ingenious in design, simple in construction, compact, while propeller dismounting is easy to maintenance, transport
Cost is low, can also improve aircraft motor performance and the bigger scope of application, fault rate is reduced, so with wide market
Prospect.
Although the utility model is to be described with reference to specific embodiments, this description is not meant to the utility model
