Embodiment, belong to the scope of protection of the invention.
Fig. 1-4 are referred to, the present invention provides a kind of technical scheme：A kind of unmanned plane is supported with reinforcement type foldable legs, bag
Include bearing plate 1, reinforcing bar 2, screwed hole 3, connecting rod 4, threaded rod 5, fix bar 6, support bar 7, balancing pole 8, bumper 9, subtract
Spring 10, mounting bracket 11, movable pulley 12, yielding rubber circle 13, trip bolt 14, fixed jack 15 are shaken, the lower section of bearing plate 1 is set
Reinforcing bar 2 is equipped with, and the inner side of reinforcing bar 2 offers screwed hole 3, the both sides of connecting rod 4 are provided with threaded rod 5, and threaded rod 5
It is connected with screwed hole 3, the screw thread on the surface of threaded rod 5 of the both sides of connecting rod 4 trend is in opposite direction, and connecting rod 4 and 2 spiral shells
The length sum of rasp bar 5 is more than the spacing of 2 screwed holes 3, it is ensured that connecting rod 4 can be installed with reinforcing bar 2, so as to improve 2
Stability between reinforcing bar 2, reduce the situation that reinforcing bar 2 shakes, so as to improve overall stability, reinforcing bar 2
Lower section is connected with fix bar 6, and reinforcing bar 2 has 2 on the center line symmetrical setting of bearing plate 1, and reinforcing bar 2 is arranged to bevelled junction
Structure, and reinforcing bar 2 is integrated with fix bar 6, and inclined structure plays a part of the pressure of buffering, while skewed
Structure be advantageous to reduce the resistance of air-flow, integrated structure is easy to improve stability, the support bar 7 of fix bar 6 and lower section
It is connected with each other, fix bar 6 forms the structure of rotation with support bar 7, and both are the equal cylindrical-shaped structure of diameter, are convenient for
Folding storage, reduce overall volume, so as to the convenient cost for carrying out packed and transported, reducing transport, the outside installation of fix bar 6
There is trip bolt 14, support bar 7 is connected by the balancing pole 8 of lower section with bumper 9, and bumper 9 is located at the two of balancing pole 8
Side, damping spring 10 is located at the lower section of balancing pole 8, and damping spring 10 is connected by the mounting bracket 11 of lower section with movable pulley 12
Connect, movable pulley 12 equally arranges in the lower section of balancing pole 8, is contacted with ground, reduces frictional force, improves to balancing pole
