Specific embodiment
In order to which those skilled in the art are better understood from the utility model, below in conjunction with the accompanying drawings with following embodiment to this
Utility model is described in further detail.
Embodiment 1
A kind of unmanned plane propeller fixed mechanism, including propeller and the shaft 1 being arranged on unmanned plane, feature exists
In：The straight 2 that two slot bottoms are inclined plane shape is symmetrically arranged on 1 circumference of shaft, 2 end of straight is connected to spiral shell
Sliding slot 3 is revolved, limit hole 4 is provided at the 3 end end of spiral chute, 4 depth of limit hole is more than 3 depth of spiral chute, propeller
Including symmetrically arranged blade 14 on axle sleeve 5 and 5 both sides circumference of axle sleeve, 5 center of axle sleeve is axis hole, horizontal footpath on 6 inner wall of axis hole
To opening up there are two symmetrical mounting hole 12, lock hole 7 is symmetrically arranged in 6 both sides of axis hole on 5 end face of axle sleeve, is set in mounting hole 12
It is equipped with cylindrical fixed block 10,10 end of fixed block is arranged with worm gear 13, between 12 bottom hole of 10 bottom surface of fixed block and mounting hole
Spring 11 is provided with, 10 top of fixed block is inclined plane shape, and worm screw 8, mounting hole 10 and 7 hole wall of lock hole are provided in lock hole 7
Upper place offers the opening 9 interconnected, and worm screw 8 is engaged with worm gear 13 by opening 9.
Operation principle：When needing to install propeller, propeller shaft is covered and is fixed in block alignment shaft directly
The opening of line sliding slot, at this time the distance between two fixed block tops be equal to the distance between two straight openings, with
The distance between slip of the fixed block in slot, straight constantly increase, the bottom surface of straight inclined plane shape guiding with
Under extruding, fixed block constantly to mounting hole contract and compresses the spring in mounting hole, when fixed block slides into straight end
During end, fixed block enters spiral chute, and fixed block shrinkage degree is maximum at this time, makes fixed block along spiral by rotating screw
Sliding slot slides into the limit hole at the end, and /V hole depth is more than spiral chute, so as to which fixed block is fallen under the action of the spring
In limit hole, the inclined-plane on fixed block top facing away from the limiting stand of spiral chute and limit hole junction at this time, and fixed block can not
Limit hole is exited, so that propeller is secured firmly in shaft.
When needing to carry out relief chamber to propeller, first with rotating handles rotary worm, worm screw is made 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 to generate slip between the inclined-plane on top and limiting stand and squeeze, so as to again fixed block be made to be collapsible into mounting hole, Gu
Determine block and exit limit hole, so as to smoothly take out propeller.
The utility model can realize the fixation and dismounting of propeller by purely mechanic mechanism, be filled compared to existing fixation
Put, the utility model structure is simpler, more convenient operation, it is only necessary to it is simple rotate twice propeller can both be carried out installation with
It fixes, and need not be by other external instruments in the installation of propeller is fixed, really realization, which is voluntarily torn open, turns, dismounting
In there is no all multiple components such as other bolt nuts, without to parts carry out it is troublesome collect take care of, also prevent zero
The influence that the loss of component dismounts propeller.
