Description

Technical Field

[0001] The present invention relates to the technical field of gyroplane wings, in particular to a gyroplane wing which is easy to disassemble. Background Art

[0002] An autogyro, also often called a gyroplane, gyroplane, or gyroplane, is a type of rotorcraft that uses the relative airflow during forward flight to generate lift by rotating its rotors. Like a helicopter, an autogyro uses its rotors as its primary lift mechanism, but the power source for the rotors is different. To take off, an autogyro must glide along the ground, with the required pull or thrust coming from propellers at the front or rear of the fuselage. The oncoming wind drives the rotors, but unlike a windmill, they rotate in a counter-clockwise direction. During forward flight, the rotor blades of an autogyro tilt backward, rather than forward like a helicopter.

[0003] With the continuous improvement of science and technology, the application of gyroplanes in people's lives has become more and more extensive. Many recreational civil gyroplanes have also appeared in life. In such gyroplanes, the wing is one of the important parts. However, the existing gyroplanes cannot be quickly disassembled and installed when in use, which makes it easy to lose comprehensive protection and maintenance of the wing. Summary of the Invention

[0004] The object of the present invention is to provide a gyroplane wing that is easy to disassemble, so as to achieve the purpose of being easy to use.

[0005] To achieve the above object, the present invention provides the following technical solution: a gyroplane wing that is easy to disassemble, comprising a wing hub, a connecting structure and a disassembly structure,
