Description

Technical Field

[0001] The utility model relates to the technical field of model airplanes, in particular to a wing folding mechanism. Background Art

[0002] Model airplanes, or aviation models in full, refer to aircraft that are heavier than air and cannot carry people but meet certain technical requirements. The composition of model airplanes is similar to that of manned aircraft, and is mainly composed of five parts: wings, tail, fuselage, landing gear, and engine. Among them, the wings are the device that generates lift when the model airplane is flying, and are an important component that can maintain the lateral stability of the model airplane during flight.

[0003] Most existing model aircraft products can only be equipped with one type of wing, and the wing is difficult to adjust according to needs, which makes it impossible for students to observe the difference in the movement of different wings when driven by wind. In particular, model aircraft products have complex structures and are relatively expensive. Purchasing multiple model aircraft products with different wings will also increase the financial burden on students, which will lead to certain limitations in the use of model aircraft products. In summary, existing model aircraft products still have the following problems:

[0004] Model aircraft wings are difficult to adjust as needed, making it impossible for students to observe the differences in the movement of different wings when driven by wind. Utility Model Content
