Fixed-wing aircraft refers to aircraft whose wings are fixed to the fuselage and do not move relative to the fuselage, and which generates lift by the force of air on the wings. Specifically, it is a heavier-than-air aircraft that flies in the atmosphere, with forward thrust or pulling force generated by a power device and lift generated by the fixed wings of the fuselage. In fixed-wing aircraft, the fuselage and the wings are generally connected by welding or glue, which makes it inconvenient to disassemble and assemble, especially during disassembly, transportation, inspection, repair, and replacement operations.

[0028] like Figure 1-7 As shown, a fixed-wing aircraft that can be quickly disassembled and assembled includes an aircraft body 1, and fixed wings 2 are symmetrically installed on both sides of the aircraft body 1. The side of the aircraft body 1 is provided with a mounting opening 3 for mounting the fixed wings 2. A fixing device 4 for fixing the fixed wings 2 is symmetrically installed in the mounting opening 3, and the fixing device 4 is driven by a transmission mechanism 5 to fix the fixed wings 2. The reinforcement rod of the fixed wing 2 is inserted into a mounting hole 6 opened at the center of the mounting opening 3, and a tightening mechanism 7 is installed below the reinforcement rod.

[0029] The fixing device 4 includes a body 401 embedded in the installation opening 3, a clamping groove 402 is provided at the front center of the body 401, a fixing bolt 407 is symmetrically installed above the clamping groove 402, and a mounting hole matching the fixing bolt 407 is provided at the connecting end of the fixed wing 2. A plurality of symmetrically distributed positioning holes 403 are provided on the side wall of the clamping groove 402, and a positioning rod matching the positioning holes 403 is installed on the fixed wing 2, which not only plays a positioning role but also can strengthen the connection. A bottom block 404 is installed below the clamping groove 402, and an adjustment block 405 is slidably installed above the bottom block 404. The bottom block 404 is a top beveled cut structure, and a matching beveled cut surface is installed at the bottom of the adjustment block 405; the top of the adjustment block 405 is a parallel surface structure, and the upper end surface of the adjustment block 405 and the fixing bolt 407 clamp and fix the fixed wing 2. The adjusting block 405 and the bottom block 404 are fixedly connected together by a threaded rod, and the threaded rod is driven to rotate by a driven gear 406, and the driven gear 406 is connected to the transmission mechanism 5. The rotation of the threaded rod can realize the sliding of the adjusting block 405 on the bottom block 404, thereby adjusting the height of the fixed position of the adjusting block 405, and realizing effective clamping of the fixed wing 2.

[0030] A protrusion 301 is installed on the installation opening 3 , and a groove matching with the protrusion 301 is opened on the back of the body 401 . The protrusion 301 , the body 401 and the installation opening 3 are fixedly connected together by connecting bolts 408 .

[0031] The transmission mechanism 5 includes a main shaft 501, on which bevel gear 1 502 and bevel gear 2 503 are symmetrically distributed from top to bottom. Bevel gear 1 502 is engaged with bevel gear 3 504, and bevel gear 2 503 is engaged with bevel gear 4 506. Bevel gear 3 504 and bevel gear 4 506 are distributed on both sides of the main shaft 501. The center positions of bevel gear 3 504 and bevel gear 4 506 are key-connected to a rotating shaft 505, and a driving gear 507 is installed at the other end of the rotating shaft 505, and the driving gear 507 is engaged with the driven gear 406. The main shaft 501 rotates, driving the bevel gear 1 502 and the bevel gear 2 503 to rotate, and then driving the bevel gear 3 504 and the bevel gear 4 506 that are meshed therewith to rotate, and finally driving the rotating shaft 505 to rotate, and the sliding of the adjusting block 405 on the bottom block 404 is achieved through the synchronously meshing rotating driving gear 507 and the driven gear 406, so as to adjust the height of the adjusting block 405.

[0032] The main shaft 501 passes through the mounting opening 3 and is connected to a manual rotating component or an electric rotating device, such as a knob or a micro motor.

[0033] The tightening mechanism 7 includes a base 706 installed at the bottom of the installation opening 3, a telescopic rod 704 is installed at the upper end of the base 706, a top seat 703 is installed at the upper end of the telescopic rod 704, a spring 705 is installed between the top seat 703 and the base 706, and the spring 705 is sleeved on the telescopic rod 704. A connecting rod 702 is installed at the upper end of the top seat 703, and a top block 701 is installed at the upper end of the connecting rod 702. When the reinforcing rod is inserted into the installation hole 6 opened at the center of the installation opening 3, the top block 701 is pressed against the bottom of the reinforcing rod under the action of the spring 705, which plays a role in fixing the reinforcing rod, making its connection more stable, and improving the stability of the overall connection of the fixed wing.

[0034] The top of the top block 701 is provided with an arc groove matched with the reinforcing rod.

[0035] The action process of the present invention is as follows:

[0036] First, the mounting end of the fixed wing 2 is docked with the mounting opening 3, which is located at the clamping groove 402, and the fixing bolt 407 is inserted into the mounting hole and the positioning rod is inserted into the positioning hole 403 to achieve rapid positioning; then, the transmission mechanism 5 drives the threaded rod to rotate, so that the adjustment block 405 slides on the bottom block 404 until the adjustment block 405 and the fixing bolt 407 effectively clamp and fix the fixed wing 2; during this process, the reinforcing rod on the fixed wing 2 is inserted into the mounting hole 6 opened at the center position of the mounting opening 3, and under the action of the spring 705, the arc groove at the top of the top block 701 rests on the bottom of the reinforcing rod, which plays a role in fixing the reinforcing rod, making its connection more stable and improving the stability of the overall connection of the fixed wing; when disassembly is required, the transmission mechanism 5 drives the threaded rod to rotate in the reverse direction, so that the adjustment block 405 releases the fixation of the fixed wing 2, and the fixed wing can be pulled out.

[0037] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention.
