Described lower wing linking arm one end and lower wing are rigidly connected, other end perforate be arranged on wing-folding axle on and around
Wing-folding axle is rotated, and the lower rack is fixed on lower wing linking arm and concentric with wing-folding axle；
The wing-folding axle is arranged on wing fixed mount, and the gear is solid around the gear being fixed on wing fixed mount
Fixed-axis rotation.
Wherein, the upper rack and lower rack are one block of wide arc-shaped steel plate, are circumferentially machined with along circular arc equidistantly
Rectangular opening.
Wherein, the gear face is tapered, and gear tooth stretches into the rectangular opening of upper rack and lower rack and forms gear
It is secondary.
The beneficial effects of the utility model are：Fold unmanned plane wing not in the same plane, in arrangement straggly up and down,
It is hinged on respectively by wing linking arm on wing-folding axle.Gear is fixed on lower wing in its axle rotation process
Rack makes lower wing do coaxial reverse rotation around wing-folding axle under gear promotion, realizes the synchronous expansion of lower wing
With pack up, it is ensured that the aerodynamic loading that unmanned plane wing is born in flight is symmetric.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Lazy-tongs are the general designations for realizing the mechanism that multiple actuators are moved with same displacement, identical power or equal velocity.
Lazy-tongs described in the utility model are to realize unmanned plane wing around the synchronous expansion of wing-folding axle 5 and the synchronous machine packed up
Structure, the lazy-tongs be based on rack-and-pinion synchronous mechanism basis improvement and come, employing gear 6 fixes, tooth
The form that bar floats.
A kind of lazy-tongs applied to unmanned plane wing-folding as shown in Fig. 1~2, including top wing linking arm 1, under
Wing linking arm 2, upper rack 3, lower rack 4, wing-folding axle 5, gear 6, gear fixing axle 7, wing fixed mount 8, top wing
9th, lower wing 10.Wing linking arm one end and wing are rigidly connected, and other end perforate is arranged on wing-folding axle 5 around its turn
Dynamic, rack (3,4) is separately fixed on lower wing linking arm (1,2) up and down, and, wing folding. with wing-folding axle 5 with one heart
Folded axle 5 is arranged on wing fixed mount 8, and gear 6 is rotated around the gear fixing axle 7 being fixed on wing fixed mount 8.
Rack is made by one block of wide arc-shaped steel plate, and steel plate circumferentially processes equidistant rectangular opening along circular arc.
As shown in figs. 34, the end face of gear 6 is tapered, it is to avoid collided interference with the linkage of arc-shaped rack, the gear teeth of gear 6 are stretched
Gear pair is formed in the rectangular opening for entering rack, up and down the gear teeth meshing formation gear pair of rack respectively with the opposite side of gear 6.
As shown in figure 1, gear 6 along arrow A rotate clockwise when, motion is transmitted to by upper lower tooth by rack and pinion engagement
Bar, upper rack 3 drives top wing linking arm 1 to drive top wing 9 to be rotated from left to right along arrow B, and lower rack 4 drives lower wing to connect
