Background technology
The mode of glide is all adopted in the landing of the existing model of an airplane, particularly remote-controlled model aircraft, and handles the remote-controlled model aircraft landing of gliding, and belongs to the work that a kind of technology and practical operation experience combine and have certain difficulty in the model plane field.Glide landing often because of the former of all misoperations thereby cause the model of an airplane away from estimating the level point or causing the damage of aircraft for beginner or part model aircraft fan at operating aircraft.Chinese patent CN2402367.Y discloses a kind of empennage composite construction of the model of an airplane, it has fuselage, the afterbody of this fuselage has a horizontal integration face, for combining with a tailplane and vertical tail, in the perforation of the perforation of tailplane and afterbody, establish sleeve pipe, making the vertical tail bottom surface protrude out fixed bar can stablize and wear tailplane admittedly, fuselage, and it is fixing with the screw threads lock, its objective is and make model of an airplane empennage can realize quick decomposition, in conjunction with, so that carry, collect, when landing, operate not proposing further technical scheme for the above-mentioned model of an airplane easily.
Summary of the invention
The purpose of this utility model is that the problem at above-mentioned existence provides a kind of and makes the model of an airplane realize the near vertical landing when landing and can reduce the forced landing device of the model of an airplane of the damage of the model of an airplane in the landing process greatly.
The technical solution of the utility model is: a kind of forced landing device of the model of an airplane, comprise fuselage and tailplane, be provided with forced landing mechanism between described fuselage and the tailplane, above-mentioned forced landing mechanism is by pedestal, the tailplane supporting plate, the tailplane pressing plate, trip shaft, torque spring, the forced landing hook, the extension spring of forced landing hook, forced landing shaft and forced landing control line constitute, wherein: above-mentioned pedestal is arranged at afterbody, above-mentioned tailplane is installed on the tailplane supporting plate by the tailplane pressing plate, and above-mentioned tailplane supporting plate passes through trip shaft, torque spring is elasticity and is articulated in pedestal front end upper surface; Above-mentioned pedestal rearward end is colluded groove along vertically being provided with one, above-mentioned forced landing groove is by forced landing shaft and colludes being movably hinged in groove upwards, above-mentioned forced landing groove colludes the upper surface that face is fastened on tailplane supporting plate one end, above-mentioned forced landing groove extension spring is arranged between forced landing groove and the pedestal, the one end is hung near forced landing groove and the forced landing shaft junction, the other end is articulated in the bottom of pedestal, and above-mentioned forced landing control line is connected in the lower end of forced landing groove.
The utility model, as long as by tension forced landing control line, just can make tailplane pop up with horizontal plane and form a forced landing angle when the model of an airplane need land owing to adopt the forced landing mechanism that is provided with between fuselage and tailplane; And under the gas-flow resistance effect, make the whole tenesmus of the model of an airplane, thereby realized model of an airplane accuracy comparatively accurately, adopt above-mentioned forced landing mechanism not only to solve in the prior art model of an airplane existing problem of controlling of landing of gliding, and greatly reduce the spoilage of the model of an airplane, for the model of an airplane provides a kind of new product.
The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 2 is the utility model part dismounting figure;
The state diagram that Fig. 3 opens when being the forced landing of the utility model empennage;
The specific embodiment
As shown in Figures 1 to 4, the utility model comprises fuselage and tailplane 13, be provided with forced landing mechanism between described fuselage and the tailplane 13, above-mentioned forced landing mechanism is by pedestal 1, tailplane supporting plate 2, tailplane pressing plate 3, trip shaft 4, torque spring 5, forced landing hook 6, forced landing hook extension spring 7, forced landing shaft 8 and forced landing control line 11 constitute, wherein: above-mentioned pedestal 1 is arranged at afterbody, above-mentioned tailplane 13 is installed on the tailplane supporting plate 2 by tailplane pressing plate 3, and above-mentioned tailplane supporting plate 2 is by trip shaft 4, torque spring 5 is elasticity and is articulated in pedestal 1 front end upper surface; Above-mentioned pedestal 1 rearward end is colluded groove 1a along vertically being provided with one, above-mentioned forced landing groove 6 is by forced landing shaft 8 and colludes being movably articulated in and colluding among the groove 1a upwards, above-mentioned forced landing groove 6 colludes the upper surface that face is fastened on tailplane supporting plate 2 one ends, above-mentioned forced landing groove extension spring 7 is arranged between forced landing groove 6 and the pedestal 1, the one end is hung near forced landing groove 6 and forced landing shaft 8 junctions, the other end is articulated in the bottom of pedestal 1, and above-mentioned forced landing control line 11 is connected in the lower end of forced landing groove 6.Above-mentioned pedestal 1 is provided with two hole seat 1b, above-mentioned torque spring 5 is placed between the two hole seat 1b, above-mentioned tailplane supporting plate 2 two ends are provided with the sign indicating number plate 2a of the tape spool hole 2b of a symmetry, and above-mentioned trip shaft 4 fuses pedestal 1, tailplane supporting plate 2 and torque spring 5 by hole seat 1b and sign indicating number plate 2a, axis hole 2b.
Above-mentioned tailplane supporting plate 2 upper surfaces are provided with the pillow block 2c of band screw, described tailplane 13 socket-connects by through hole and tailplane supporting plate 2, the pillow block 2c that is arranged at its aerofoil, above-mentioned tailplane pressing plate 3 corresponding pillow block 2c places are provided with installing hole 3a, in installing hole 3a, be provided with tailplane supporting plate 2 on the bolt 14 of pillow block 2c screw Joint.Above-mentioned forced landing groove 6 is a strip shape body, and body 61 is colluded in its upper end, and to be the oblique triangle that extends down in a top hook-shaped.
The principle of groundwork process of the present utility model is, when the model of an airplane during at normal flight, the duty of forced landing mechanism as shown in Figure 1, the forced landing mechanism of this moment is because the effect of forced landing hook extension spring 7, tailplane supporting plate 2 is caught on tightly.When forced landing line 11 during in normality, tailplane remains horizontal level.At this moment which kind of operation the control line 9 that force-lands carries out can not have influence on forced landing mechanism, and at this moment aircraft can be finished normal remote control distributor and other actions of gliding.When needs adopt the vertical landing mode, as long as tension forced landing control line 11 makes forced landing groove emission levels empennage supporting plate 2, this moment, tailplane 13 just can be under the drive of tailplane supporting plate 2 as shown in Figure 3, form a forced landing angle, thus the purpose of the near vertical of implementation model aircraft landing.
