Description

Technical Field

[0001] This utility model relates to the technical field of model aircraft, specifically a quick-release structure for the main wing and fuselage. Background Technology

[0002] A fixed-wing model aircraft is an aircraft in which the wings are fixed to the fuselage and do not move relative to the fuselage during flight. The lift is generated by the difference in the vertical force exerted by the air on the wings. Generally speaking, the wings include a tail and a main wing, with the main wing being longer.

[0003] There are currently two types of quick-release structures for the main wings of fixed-wing aircraft:

[0004] 1. The main wing and fuselage need to be separated by a certain distance. The main wing servo power cable plug needs to be manually connected to the main control extension cable. Two screws need to be tightened at the front end. The operation is complicated.

[0005] 2. The main wing and the fuselage front end dock in mid-air. However, a total of four screws are needed to attach the front and rear ends of the main wing to the fuselage, increasing assembly complexity and labor costs. Alternatively, the main wing and fuselage front end dock in mid-air with two screws, while the rear end uses a rotating locking structure, which is complex and requires manual tightening by the user.

[0006] To address the aforementioned technical issues, we propose a quick-release structure for the main wing and fuselage. Utility Model Content

[0007] The purpose of this invention is to provide a quick-release structure for the main wing and fuselage to solve the problems in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a quick-release structure for a main wing and fuselage, comprising a fuselage and a main wing, wherein a male main wing fixing member is provided at the rear end of the main wing, and a female fuselage fixing member is provided at the fuselage to cooperate with the male main wing fixing member; a main wing servo connector is provided at the front end of the main wing, and a fuselage main control connector is provided at the fuselage to cooperate with the main wing servo connector.

[0009] Preferably, the male wing fixing component is a plastic pin, and the female fuselage fixing component is a pin hole.

[0010] Preferably, the fuselage main control connector consists of a main control connector body and a slot, and the main wing servo connector consists of a servo connector body and a plug rod. The main control connector body and the servo connector body cooperate with each other, and the slot and the plug rod cooperate with each other.

[0011] Preferably, there are two slots and two inserts.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the male connector of the main wing is inserted into the groove of the female connector of the fuselage. The main wing rotates clockwise. When the main wing is close to the horizontal position, the main wing servo connector and the main control extension connector complete the aerial docking. Then, the front end of the main wing is fixed to the fuselage with two screws; the rear end of the main wing is combined with the fuselage using a plastic pin structure, and the front end is connected to the fuselage using an aerial docking structure with the main wing servo power cable plug and the main control extension cable plug.
