Compared with prior art, this have the advantage that：
A kind of propeller fast assembling-disassembling self-locking mechanism provided by the invention, analyzes above-mentioned propeller fast assembling-disassembling self-locking mechanism
Primary structure known to：The propeller fast assembling-disassembling self-locking mechanism mainly by propeller, propeller mounting device, self-locking axis pin,
Self-lock pin axle cap, embedded counterpart and offsetting spring structure part composition；Above-mentioned propeller fast assembling-disassembling self-locking mechanism can be right
Motor output shaft forms more fastening and easy-to-dismount connection；(i.e. it should be noted that propeller, propeller mounting device,
Self-locking axis pin is socketed successively from outside to inside).
Wherein, be provided with propeller axle sleeve at the center of the propeller, extension have propeller blade (blade to this not
It repeats again, i.e., spiral sleeve is socketed in the outermost layer of entire mechanism)；
The propeller mounting device includes the installation axle axis for being located at the mounting platform of bottom and being arranged on mounting platform
Set (the installation axle axle sleeve is socketed in middle level)；The inside of the installation axle axle sleeve is provided with the first pin hole and from top to bottom
Two pin holes, and the aperture of first pin hole is less than the aperture of second pin hole；It is formed between first pin hole and the second pin hole
Limited step；And it is additionally provided with mounting hole or mounting groove on the inner wall at the first pin hole of the installation axle axle sleeve；The installation
Platform is detachably connected with motor output shaft；The outer layer of the installation axle axle sleeve is socketed in the propeller axle sleeve, the installation
The internal layer of axis axle sleeve is socketed in by embedded counterpart on the self-locking axis pin, and the embedded counterpart and the propeller shaft
The mounting hole or mounting groove insertion cooperation on set；
The self-locking axis pin be reducing axis pin, the self-locking axis pin specifically include top the first axis pin, middle part second
Axis pin and axis pin step；The outer diameter of first axis pin and the first pin hole internal diameter size phase on the installation axle axle sleeve
Together, the outer diameter of second axis pin is less than the outer diameter of first axis pin, and the outer diameter of the axis pin step
It is identical as the second pin hole internal diameter size on the installation axle axle sleeve；The resetting spring is set in the second of the self-locking axis pin
On axis pin, and the limited step is used to be limited in the top of the resetting spring, and the axis pin step is described for being limited in
The bottom of resetting spring；The self-lock pin axle cap is detachably connected on the first axis pin of the self-locking axis pin.
It is analyzed it is found that when carrying out fast quick-detach according to above structure, user only needs firmly that self-lock pin axle cap is related
(compression spring is shunk pull-up certain distance self-locking axis pin at this time, while self-lock pin axis moves up, and hereafter insertion is matched straight up
The corresponding installation site of component is at smaller second axis pin of outer diameter by larger the first axis pin variation of outer diameter), it is embedding at this time
Enter counterpart departing from (i.e. ball or roller) immediately be detached from propeller mounting device installation axle axle sleeve on mounting hole or
It is mounting groove, then realizes unlock, then propeller mounting device and motor output shaft is detached from and dismantled；
When being installed, user needs first by propeller axle sleeve installation set on propeller mounting device, then by spiral shell
Rotation paddle mounting device installs, i.e., first will embedded counterpart (i.e. ball or roller) be put into installation axle axle sleeve mounting hole or
Then to penetrate self-locking axis pin and resetting spring from the bottom of installation axle axle sleeve in mounting groove, then by self-lock pin axle cap from
The bottom of installation axle axle sleeve is connected to fixed on self-locking axis pin (at this time due to the cooperation of embedded counterpart and mounting hole or mounting groove
Effect, it will make embedded counterpart that there is the movement tendency expanded outward, and then realize embedded counterpart to installation axle axle sleeve with
And the effect of propeller axle sleeve expansion fastening)；Finally motor output shaft is embedded into the axle sleeve of propeller mounting device.It is installing
After good, the installation site of embedded counterpart can be suitably adjusted, then pressing self-lock pin axle cap is loosed one's grip, being embedded in counterpart at this time can
To better lock onto in mounting hole or mounting groove and (automatic locking can be realized)；It will be apparent that realized by above structure
Lock mode locks motor output shaft and propeller mounting device, and locking mode is more secured, stability is stronger, tears open simultaneously
It unloads and installation operation is also more simple and efficient；
To sum up, propeller fast assembling-disassembling self-locking mechanism provided in an embodiment of the present invention has simple in structure, operation operation side
Just, novel design is reasonable, is convenient for rapidly and efficiently many technical advantages such as dismounting propeller.

Axle sleeve 22；The inside of the installation axle axle sleeve 22 is provided with the first pin hole 23 and the second pin hole 24 from top to bottom, and described
The aperture of first pin hole 23 is less than the aperture of second pin hole 24；Limiting stand is formed between first pin hole 23 and the second pin hole 24
Rank 25；And it is additionally provided with mounting hole 26 or mounting groove (not shown) on the inner wall at the first pin hole 23 of the installation axle axle sleeve；
The mounting platform 21 is detachably connected with motor output shaft 7；The outer layer of the installation axle axle sleeve 22 is socketed in the propeller
In axle sleeve 11, the internal layer of the installation axle axle sleeve 11 is socketed in by embedded counterpart 5 on the self-locking axis pin 3, and described embedding
Enter the mounting hole 26 on counterpart 5 and the propeller axle sleeve 11 or mounting groove insertion cooperation (referring specifically to Fig. 5)；
The self-locking axis pin 3 is reducing axis pin, and the self-locking axis pin 3 specifically includes first axis pin 31 at top, middle part
The axis pin step 33 of second axis pin 32 and bottom；The outer diameter of first axis pin 31 and first on the installation axle axle sleeve
23 internal diameter size of pin hole is identical, and the outer diameter of second axis pin 32 is less than the outer diameter of first axis pin 31, and institute
The outer diameter for stating axis pin step 33 is identical as 24 internal diameter size of the second pin hole on the installation axle axle sleeve；The resetting spring
6 are set on the second axis pin 32 of the self-locking axis pin, and the limited step 25 is used to be limited in the top of the resetting spring 6
Portion, the axis pin step 33 then are used to be limited in the bottom of the resetting spring 6；The self-lock pin axle cap 4 is detachably connected on
(referring specifically to Fig. 6 and Fig. 7 and Fig. 8) on first axis pin 31 of the self-locking axis pin 3.
It should be noted that the inner diameter size at the first pin hole of installation axle axle sleeve should be with the first of self-locking axis pin
Outer diameter at axis pin is adapted, and can ensure to form the pin hole matching relationship of fastening in this way.Self-locking axis pin is to become simultaneously
Diameter axis pin its self-locking mechanism is of crucial importance.
It should be noted that in the concrete structure of rotation paddle fast assembling-disassembling self-locking mechanism；The rotation paddle fast assembling-disassembling is from lock machine
Structure (includes mainly mounting platform and installation axle axis by propeller (center is propeller axle sleeve), propeller mounting device
Set), self-locking axis pin, self-lock pin axle cap, the structures such as self-locking ball or roller, resetting spring constitute.Propeller mounting device passes through
