The specific embodiment

Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.

As shown in Figure 1, a SUAV (small unmanned aerial vehicle) ejector, comprises that pin is stepped on projector 1, elastic force preloader 2, launched pulley yoke 3, front adjustable support 4, rear adjustable support 5, guide-rail plate 6, front arm 13, rear arm 14, pulley 15, adapter plate 16, hook 17 and stretch cord 24, described pin is stepped on projector 1 and is provided with pedal 25, and described pedal 25 is by steel wire 12 coupling hooks 17, described preloader 2, in described guide-rail plate 6 belows, is provided with tray 23 and anti-reverse clamp button of the spring 20 in described preloader 2, in described preloader 2 outsides, be also provided with crank 11, described stretch cord 11 one end connections are wound on described tray 23, one end is through after described guide-rail plate 6 in addition, described in being connected to, launch pulley yoke 3 near one end of described front adjustable support 4, by hand crank 11, drive the tray 23 in elastic force preloader 2 to rotate, stretch cord 24 is hoisted by tray 24, stretch cord 24 is elongated under the effect of tray 23, the elastic force producing is applied to and launches on pulley yoke 3, the tray 24 that elastic force preloader is 2 li has anti-reverse clamp button of the spring 20 pinnings can not reverse, anti-reverse clamp button of the spring 20 can manually unclamp and unclasp stretch cord 24.Described front adjustable support 4 and rear adjustable support 5 are hinged on respectively described guide rail 6 two ends; Described guide-rail plate 6 is provided with slideway 19; Described front adjustable support 4 and rear adjustable support 5 are all comprised of two telescopic bars, before launching unmanned plane, by adjusting adjustable support 4 and the length of 5 two telescopic rods of rear adjustable support, the opening angle of two telescopic rods adjust and launch unmanned plane levelness and launch the elevation angle.

As shown in Figures 2 and 3, described pulley 15 have a plurality of and by the paired symmetry of rotating shaft, be arranged on described in launch on pulley yoke 3, described pulley 15 is in the interior rolling of described slideway 19; The described pulley yoke 3 that launches is provided with in the one end near described rear adjustable support 5 pocket for the punch head 18 matching with described hook 17, described front arm 13 and rear arm 14 one end are hinged on described guide-rail plate 6, and the other end is hinged on described adapter plate 16 lower surfaces by permanent seat 21.At described adapter plate 16 upper surfaces, be provided with hold down groove 10, the upper surface place directly over described adapter plate 16 is hinged with described rear arm 14 is also provided with buckle slot 7, at the interior hinged buckle 8 of described buckle slot 7.At SUAV (small unmanned aerial vehicle) 22 ventrals, clamp 9 is installed, described clamp 9 is loaded on described adapter plate 16 by described hold down groove 10 and buckle 8, before launching SUAV (small unmanned aerial vehicle), 9 pairs of good adapter plates 16 of supporting clamp are installed on SUAV (small unmanned aerial vehicle) ventral, shift backward again the end onto, buckle 8 is locked in the draw-in groove of the supporting clamp 9 of ventral, thereby fixes SUAV (small unmanned aerial vehicle), will launch pulley yoke 3 along slideway 19 adjustable support 5 directions slips backward until pocket for the punch head 18 is hooked by hook 17 simultaneously.

First, by front adjustable support 4, rear adjustable support 5 is adjusted and is launched unmanned plane levelness and launch the elevation angle, by as mentioned above SUAV (small unmanned aerial vehicle) being fixed by clamp 9 and adapter plate 16, then will launch pulley yoke 3 along slideway 19 adjustable support 5 directions slips backward until pocket for the punch head 18 is hooked by hook 17, again by the crank 11 on hand elastic force preloader 2, stretch cord 24 is elongated under the effect of tray 23, the shrinkage tensions of stretch cord 24 increases, reach and launch the rotation that stops shaking crank 11 on stretch cord preloader 2 after pulling force, the anti-reverse spring buckle 20 that preloader is 2 li pins tray 23 and can not reverse, complete after above-mentioned action, unclamp anti-reverse spring buckle 20 and unclasp stretch cord, pin steps on the pedal 25 that pin is stepped on projector 2, pedal 25 pulls the steel wire 12 of coupling hook 18, hook 12 actions, launching stretch cord 24 shrinkage tensions effects that pulley yoke 3 connected hauls along the slideway 19 on guide-rail plate 6 to front slide, arrive after guide-rail plate 6 front ends, adapter plate 16 moves downward under force of inertia effect, in this process, the angle of front arm 13 and rear arm 14 is rotated forward, described rear arm 14 upper ends are provided with rotates buckle projection 26, the described buckle 8 of described buckle projection 26 contact, rotation buckle projection 26 effect buckles 8 on rear arm 13, after buckle 8 rotates completely in buckle slot 7, thereby buckle 8 does not work to SUAV (small unmanned aerial vehicle) 22, unmanned plane moves forward under the effect of inertia, reach the object of catapult-assisted take-off.

The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
