Embodiment
In order to which those skilled in the art are better understood from the present invention, below in conjunction with the accompanying drawings with following examples to the present invention
It is described in further detail.
Embodiment 1
A kind of quick-detachable unmanned plane propeller fixed mechanism, including propeller and the rotating shaft that is arranged on unmanned plane
1, it is characterised in that：The straight 2 that two bottom lands are inclined plane shape, the end of straight 2 point are symmetrically arranged with the circumference of rotating shaft 1
Spiral chute 3 is not connected with, spacing hole 4 is provided with the end end of spiral chute 3, it is deep that the depth of spacing hole 4 is more than spiral chute 3
Degree, propeller include symmetrically arranged blade 14 on axle sleeve 5 and the both sides circumference of axle sleeve 5, and the center of axle sleeve 5 is axis hole, the inwall of axis hole 6
Upper horizontal radial offers two symmetrical fixing holes 12, and lock hole 7 is symmetrically arranged with the both sides of axis hole 6 on the end face of axle sleeve 5, fixed
The fixed block 10 of cylinder is provided with hole 12, the end of fixed block 10 is arranged with worm gear 13, the bottom surface of fixed block 10 and fixing hole 12

Locate to offer the opening 9 interconnected on the hole wall of hole 7, worm screw 8 is engaged with worm gear 13 by opening 9.
Operation principle：It is straight in fixation block alignment rotating shaft that propeller shaft is put when needing to install propeller
The opening of line chute, now the distance between two fixed block tops be equal to the distance between two straight openings, with
Slip, straight the distance between of the fixed block in groove constantly increase, the bottom surface of straight inclined plane shape guiding with
Under extruding, fixed block constantly to fixing hole contract and compresses the spring in fixing hole, when fixed block slides into straight end
During end, fixed block enters spiral chute, and now fixed block shrinkage degree is maximum, makes fixed block along spiral by rotating screw
Spacing hole at slide to the end, spacing hole depth are more than spiral chute, so as to which fixed block is fallen under the action of the spring
In spacing hole, now the inclined-plane on fixed block top facing away from the limiting stand of spiral chute and spacing hole junction, and fixed block can not
Spacing hole is exited, so that propeller is secured firmly in rotating shaft.
When needing to carry out relief chamber to propeller, first with rotating handles rotary worm, worm screw is set to drive turbine rotation, from
And fixed block is rotated, the inclined-plane on fixed block top is gone in face of limiting stand by rotating, then is made admittedly by rotating screw
Determine block and slip and extruding are produced between the inclined-plane on top and limiting stand, so as to make fixed block be collapsible into fixing hole again, Gu
Determine block and exit spacing hole, so as to smoothly take out propeller.
The present invention can realize the fixation and dismounting of propeller by purely mechanic mechanism, compared to existing fixing device,
Structure of the present invention is simpler, more convenient operation, it is only necessary to and simple rotate twice can be both installed with being fixed to propeller, and
