The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also shown in Figure 1ly, Fig. 1 is the perspective view of the utility model model of an airplane.The utility model provides a kind of anticollision device, collision-prevention device of the model of an airplane, comprises fuselage 1, is installed in the inner engine 2 of fuselage 1, is arranged at the undercarriage 4 and the empennage 5 that is arranged at fuselage 1 rear end of fuselage 1 bottom.
The top of fuselage 1 is provided with a rotating shaft that is connected with engine 2, drives rotating shaft through transmitter 2 and rotates, and be installed with screw 3 in the rotating shaft, and at the top of rotating shaft, the top of said screw 3 is equipped with anticollision device, collision-prevention device 6.
See also shown in Figure 2ly, Fig. 2 is the package assembly sketch map of the utility model model of an airplane top anticollision device, collision-prevention device.Wherein said anticollision device, collision-prevention device 6 includes and anti-rams 7, damping spring 13 and main revolves 14.
Anti-raming 7 is made up of crashproof cap 8, outer tube 9 and inner sleeve 10; Said outer tube 9 is positioned at crashproof cap 8 bottoms; Inner sleeve 10 is arranged in outer tube 9, and protrudes in outer tube 9, leaves the gap between inner sleeve 10 and the outer tube 9; Also be provided with pin-and-hole 11 and inner sleeve 10 protrudes in the part of outer tube 9, this pin-and-hole 11 runs through whole inner sleeve 10.
