Detailed description of the invention
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
As depicted in figs. 1 and 2, screw propeller draw off gear for unmanned plane of the present utility model, comprise the horn 1 of base plate more than 7, three, center ring 6, drive element 5 and belt wheel transmission parts 8, the horn 1 of more than three is circumferentially arranged on base plate 7 successively, one end of horn 1 to be articulated with on base plate 7 by axle and can to rotate around hinge-point, and the other end of horn 1 is used for installing unmanned plane screw propeller assembly.Center ring 6 is positioned at the middle part of base plate 7, and center ring 6 is provided with Timing Belt tooth, and drive element 5 drives center ring 6 to rotate by belt wheel transmission parts 8, Timing Belt 3.Region on base plate 7 between center ring 6 and base plate 7 outward flange is provided with the space that can hold all horns 1.Be provided with connecting rod 2 between each horn 1 and center ring 6, namely one end of connecting rod 2 is articulated with on horn 1, and the other end of connecting rod 2 is articulated with on center ring 6.When center ring 6 rotates time, will move by drivening rod 2, thus drive horn 1 to realize being synchronized with the movement by connecting rod 2, reach the object that horn 1 is folding or open.Because the motion of horn 1 is for rotating, when carrying out folding, each horn 1 can turn in the region of base plate 7 completely, and horns 1 all like this can not expose, to ensure best portability.
