Abstract

The utility model provides a gliding model aircraft which can adjust the positive dihedral angle on a main wing. The utility model includes an airframe, a main wing, a stabilizer, a vertical tail, a wing pressure sheet and a fastening elastic ribbon; the gliding model aircraft is characterized by also including a bearing plate, a supporting plate of the main wing, a lifting bolt and an adjusting nut; two bearing plates are arranged in V shape at two sides of the airframe below the main wing; a hinged supporting plate of the main wing is arranged on the supporting plate; the upper end of the lifting bolt is connected with the supporting plate of the main wing, and the lifting bolt penetrates the through hole of the airframe and is connected with the adjusting nut arranged in a transverse through hole which is arranged in the middle of the airframe; the wing pressure sheet, the main wing and the fastening elastic ribbon and a hanging rod of the elastic ribbon at the two sides of the airframe of the supporting plate of the main wing are fastened on the airframe; the positive dihedral angle on the main wing of the utility model can be adjusted with the speed of air; thereby obtaining the best flying effect; the gliding model aircraft also has the advantages of simple structure, being easy to be manufactured and being convenient for being adjusted.

Description

The glide model of an airplane at the adjustable host wing upper counterangle

Affiliated technical field

The utility model relates to toy airplane, the glide model of an airplane at particularly a kind of adjustable host wing upper counterangle.

Background technology

The movable fan of the glide model of an airplane has such cognition: adopt the upper counterangle bigger when wind is comparatively gentle, during promptly near straight wing, the glide model of an airplane can obtain to glide steadily, flight glide effect far away, and when wind is bigger, the model of an airplane that wing is comparatively straight is swing with the wind easily just, generation is moved swiftly, under the also very fast sometimes bob; If when adopting the less and wing in the upper counterangle, the wind resistance of the model of an airplane is relatively good, and lift-off easily, but not enough be that gliding ability is relatively poor.Because the existing glide model of an airplane just fixes wing when making, promptly the upper counterangle of wing is inalterable, can't make adaptive adjustment with wind and wind speed when being at play.Sometimes just do not make the people feel very disappointing when the upper counterangle of wing is corresponding with wind speed, for this reason, some people have to be with several the different glide model of an airplanes in the wing upper counterangle to play more, and this can't but be the defective of prior art.

Summary of the invention

For the wing that makes the glide model of an airplane can change its upper counterangle with wind, the utility model provides the glide model of an airplane at a kind of adjustable host wing upper counterangle, and the wing upper counterangle of this glide model of an airplane can arbitrarily be adjusted, and regulates very convenient.

Above-mentioned task realizes by this way: the glide model of an airplane at a kind of adjustable host wing upper counterangle, include fuselage, host wing, tailplane, vertical tail, wing compressing tablet and fastening elastic, it is characterized in that support plate in addition, the host wing supporting plate, lifting screw and adjusting nut, two V-shaped layouts of support plate are placed in the fuselage both sides of host wing below, hinge-type host wing supporting plate is placed on the support plate, the upper end of lifting screw is articulated on the middle jointed shaft of host wing supporting plate, the through hole adjusting nut interior with being placed in fuselage intermediate lateral through hole that its shaft passes fuselage is connected, the centre of described host wing has V-type groove longitudinally, host wing is positioned on the host wing supporting plate, the wing compressing tablet is positioned on the host wing, two fastening elastics respectively about fuselage with the wing compressing tablet, host wing and host wing supporting plate are tied up, and are connected the wing compressing tablet with the elastic peg of fuselage with its two ends, host wing and host wing supporting plate are anchored on the fuselage.

From technique scheme as can be seen, just can allow lifting screw move up and down when the turn adjusting nut, the jointed shaft that drives the host wing supporting plate moves up and down.Owing to be subject to support plate below two hinged flat boards of host wing supporting plate, thereby the last angle of host wing supporting plate is changed, allow the also change thereupon of the upper counterangle of the host wing that has V-shaped groove.Just because of corresponding adjustment can be made with the wind and the wind speed of environment in the host wing upper counterangle of this glide model of an airplane, obtain best flight effect, fully satisfied people's the requirement of playing, overcome the deficiency of the existing glide model of an airplane effectively, increased the interest that people play greatly, and can promote the understanding of teenager to wing and wind speed correlation by adjusting, further cultivated teen-age thinking ability.In addition, the utility model structure is comparatively simple, make easily, and also easy to adjust.

The specific embodiment

With reference to Fig. 1～Fig. 3, the glide model of an airplane at a kind of adjustable host wing upper counterangle, include fuselage 1, host wing 2, tailplane 3, vertical tail 4, wing compressing tablet 5 and fastening elastic 6, the technical program also has support plate 7, host wing supporting plate 8, lifting screw 9 and adjusting nut 10.Two support plate 7 V-shaped layouts are placed in fuselage 1 both sides of host wing 2 belows.Host wing supporting plate 8 is a hinge-type,, and is placed on the support plate 7 by jointed shaft 12 hinged forming by two flat boards 11.The through hole 13 that fuselage 1 is passed in jointed shaft 12 sockets in the middle of the top of lifting screw 9 and the host wing supporting plate 8, its shaft and the intermediate lateral through hole that is placed in fuselage 1 14 interior adjusting nuts 10 are connected.The centre of host wing 2 of the present utility model has V-type groove 15 longitudinally, so that the adjustment at its upper counterangle.This host wing 2 is laid and is placed on the host wing supporting plate 8, and described wing compressing tablet 5 is preferably butterfly shape, helps wing compressing tablet 5 and is close on the host wing 2, and host wing supporting plate 8 of the present utility model and wing compressing tablet 5 can be made with plastics or sheet metal.As prior art, the utility model still adopts two fastening elastics 6 in fuselage 1 both sides wing compressing tablet 5, host wing 2 and host wing supporting plate 8 to be tied up respectively, and is connected with the elastic peg 16 of fuselage 1 with its two ends wing compressing tablet 5, host wing 2 and host wing supporting plate 8 are anchored on the fuselage 1.
