Description

Technical Field

[0001] This utility model belongs to the field of toy airplane technology and relates to a hand-launched rotary model airplane. Background Technology

[0002] A hand-launched rotary model airplane is a toy airplane that is thrown manually and returns to the vicinity of the launch point after flying one circle. When using it, the user needs to adjust the movable parts, such as the wings, to achieve the rotary effect. However, most current model airplanes have complex structures, making them difficult for young children to assemble and use. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a hand-launched rotary model airplane, which effectively solves the issues in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A hand-launched rotary model airplane includes:

[0006] The fuselage is plate-shaped;

[0007] A vertical tail fin is fixedly installed at the rear of the fuselage. The vertical tail fin is integrated with the fuselage. The area of ​​the vertical tail fin near the rear of the fuselage is set as a rudder area.

[0008] The rectangular socket and the arc-shaped socket are located on the fuselage below the vertical tail fin, and the arc-shaped socket is located on the fuselage near the middle.

[0009] A horizontal tail fin is inserted and installed in the rectangular socket, and the area of ​​the horizontal tail fin near the tail of the fuselage is set as a lift zone.

[0010] The wing is inserted into the arc-shaped socket, and the areas on both sides of the wing near the tail of the fuselage are set as aileron areas;

[0011] A counterweight is inserted and installed at the front end of the machine body.

[0012] Optionally, an auxiliary wing plate is fixedly connected to the aileron region on the side away from the nose, and the auxiliary wing plate is integral with the wing.

[0013] Optionally, the horizontal tail fin and the middle of the side of the wing are provided with a locking groove, and during installation, the two ends of the rectangular insertion hole and the arc-shaped insertion hole are inserted into the locking groove.

[0014] Optionally, the two sides of the wing are folded upward to form an anti-reflection zone, and the area between the two anti-reflection zones is a horizontal zone, the length of which is the same as the length of the horizontal tail fin.

[0015] Optionally, the upward reflection angle of the upward reflection zone is 7 degrees.

[0016] Optionally, the wing has a protrusion on the middle of both sides extending outwards, and the locking groove is provided on the protrusion.

[0017] Optionally, the edges of the fuselage, vertical tail, horizontal tail, and wings are all rounded.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By using a one-piece design of the plate-shaped fuselage and vertical tail, as well as the plug-in connection of the horizontal tail and wing, the number of components and installation difficulty during model aircraft assembly are reduced. The curved plug holes provide curvature for the installed wing, enabling the wing to generate a certain amount of lift. The vertical tail, horizontal tail and wing are divided into rudder area, lift area and aileron area at corresponding positions. The attitude and trajectory of the flight can be adjusted by adjusting these areas.

[0020] 2. During installation, insert the horizontal tail fin and wing into the rectangular and curved insertion holes. By setting the locking groove, the two ends of the rectangular and curved insertion holes are locked into the locking groove, which increases the stability of the connection and makes it less likely to come out in the event of a drop.

[0021] 3. By folding the wings upwards on both sides to create dihedral zones, the lateral stability of the aircraft is improved. This makes the length of the dihedral zone the same as the length of the horizontal tail, which makes it easier to use the horizontal tail as a reference to bend the dihedral zone and reduce the possibility of asymmetry between the two dihedral zones.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 and Figure 2 This invention discloses a hand-launched rotary model airplane, comprising a fuselage 1, which is plate-shaped. A vertical tail 2 is fixedly installed at the tail of the fuselage 1, and the vertical tail 2 is integral with the fuselage 1. The area of ​​the vertical tail 2 near the tail of the fuselage 1 is set as a rudder area 21. A rectangular insertion hole 31 is opened below the vertical tail 2 on the fuselage 1, and an arc-shaped insertion hole 32 is opened near the middle of the fuselage 1. To facilitate rotary flight, the rectangular insertion hole 31 has an angle of negative 9 degrees with the longitudinal axis of the fuselage. A horizontal tail 4 is inserted into the rectangular insertion hole 31. The area of ​​the horizontal tail 4 near the tail of the fuselage 1 is set as a lift area 41. A wing 5 is inserted into the arc-shaped insertion hole 32. The two sides of the wing 5 near the tail of the fuselage 1 are set as aileron areas 51. A counterweight 6 is inserted and installed at the front end of the fuselage 1.

[0027] Specifically, the integrated design of the plate-shaped fuselage 1 and vertical tail 2, as well as the plug-in connection of the horizontal tail 4 and wing 5, reduces the number of components and installation difficulty during model aircraft assembly. The curved insertion hole 32 provides curvature for the installed wing 5, enabling the wing 5 to generate a certain amount of lift. The rudder area 21, elevator area 41, and aileron area 51 are divided at corresponding positions on the vertical tail 2, horizontal tail 4, and wing 5. The attitude and trajectory of the flight can be adjusted by adjusting these areas.

[0028] In this way, the integrated plate design reduces the number of installation components, and the plug-in installation makes installation easier and more convenient to use.

[0029] In some feasible ways, the fuselage 1 can be designed in the shape of the side projection of an aircraft. The fuselage 1, vertical tail 2, horizontal tail 4 and wing 5 are all made of PP foam board material. The sides of the vertical tail 2, horizontal tail 4 and wing 5 are set as rudder area 21, elevator area 41 and aileron area 51. By bending, this area can be bent to change the flight attitude and trajectory of the aircraft. Using PP foam board material and dividing the rudder area 21, elevator area 41 and aileron area 51, the flight attitude and trajectory can be changed by bending. Without setting up a separate movable structure, the installation difficulty of the model aircraft is further reduced, making it suitable for its main users.

[0030] A through hole is provided at the front end of the body 1. The through hole is perpendicular to the surface of the body 1. The counterweight 6 is inserted into the through hole. To improve the installation stability of the counterweight 6, the counterweight 6 includes a bolt and an internally threaded tube. The bolt and the internally threaded tube are inserted from both ends of the through hole and threaded together. A baffle is fixedly connected to the end of the internally threaded tube away from the bolt, so that the bolt and the internally threaded tube are in an I-shape after connection.

[0031] As a specific embodiment of a hand-launched rotary model aircraft provided in the application, an auxiliary wing plate 511 is fixedly connected to the side of the aileron region 51 away from the nose, and the auxiliary wing plate 511 is integrated with the wing 5.

[0032] Overall, the wing 5 is relatively long, making the aileron area 51 slender. By setting an auxiliary wing plate 511, the aileron area 51 protrudes outward, providing a point of leverage for adjusting the aileron area 51 by bending it with fingers, thus facilitating adjustment.

[0033] As another specific embodiment of the hand-launched rotary model airplane provided in the application, the horizontal tail 4 and the middle of the side of the wing 5 are provided with a locking groove 33. During installation, the rectangular insertion hole 31 and the arc-shaped insertion hole 32 are inserted into the locking groove 33 at both ends.

[0034] Depending on the specific usage scenario, during installation, the horizontal tail fin 4 and the wing 5 are inserted into the rectangular socket 31 and the arc socket 32. By setting the locking groove 33, the two ends of the rectangular socket 31 and the arc socket 32 ​​are locked into the locking groove 33, which increases the stability of the connection and makes it less likely to come out when dropped.

[0035] Furthermore, the middle of both sides of the wing 5 is provided with protrusions extending outwards, and the locking groove 33 is provided on the protrusions.

[0036] It should be understood that the wing 5 is relatively long. By setting a protrusion, the length of other parts is made smaller than the position of the protrusion, which makes it easier for the wing 5 to be inserted into the arc-shaped insertion hole 32. After insertion, it is engaged by the locking groove 33 of the protrusion.

[0037] In some feasible embodiments, the tenon groove 33 is a rectangular groove.

[0038] As a specific embodiment of a hand-launched rotary model airplane provided in the application, the wings 5 ​​are folded upward on both sides to form an upward dipping zone 52, and the area between the two upward dipping zones 52 is a horizontal zone 53, the length of which is the same as the length of the horizontal tail 4.

[0039] It should be understood that by folding the upper dihedral zones 52 upwards on both sides of the wing 5, the lateral stability of the aircraft is improved, and the length of the horizontal zone 53 is the same as the length of the horizontal tail 4. This makes it easier to use the horizontal tail 4 as a reference to bend the upper dihedral zones 52, reducing the possibility of asymmetry between the upper dihedral zones 52 on both sides.

[0040] In some feasible methods, the anti-reflection angle of the anti-reflection zone 52 is preferably 7 degrees. In actual use, it can be adjusted according to the situation. When in use, the horizontal tail 4 is aligned with the middle of the wing 5, and the wing 5 is folded with the two sides of the horizontal tail 4 as the crease position to form the anti-reflection zone 52.

[0041] As a specific embodiment of a hand-launched rotary model airplane provided in the application, the corners of the fuselage 1, vertical tail 2, horizontal tail 4, and wing 5 are all rounded.

[0042] It should be understood that during use, model airplanes may come into contact with people or other objects. By setting rounded corners, impact damage can be reduced on the one hand, and the possibility of damage to the edges and corners of the model airplanes when they collide with hard objects on the other hand.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
