Embodiment 1

[0056] like Figure 2 to Figure 4 A specific implementation of the propeller quick-release device shown includes a propeller base assembly 100 as a connection base and a quick-detachable propeller 300 as a connection accessory.

[0057] Wherein, the quick-detachable propeller 300 includes a seat body 301 and at least two blades 302 that are evenly distributed in the circumferential direction on the seat body 301. The seat body 301 is formed with a positioning structure on the side facing the propeller base assembly 100 (not shown in the figure). ), the positioning structure is restricted by the propeller base assembly 100 toward the protruding part of the seat body and blocks the rotation of the seat body 301 relative to the propeller base assembly 100;

[0058] The propeller base assembly 100 includes a fixed seat 1 and a key switch 2, the fixed seat 1 is fixedly connected to the rotating part 201 of the driving device 200, and an engaging mechanism ( Not marked in the figur...

Embodiment 2

[0070] This embodiment provides an aircraft (not shown in the figure), including a fuselage and any one of the propeller quick release devices described in Embodiment 1.

[0071] The above-mentioned aircraft has the advantages described in any one of Embodiment 1 due to the adoption of the above-mentioned propeller quick release device.

Abstract

The invention provides an aircraft and a propeller fast disassembly device thereof, a fast-disassembly propeller and a propeller base component. The propeller fast disassembly device comprises a fast-disassembly propeller and a propeller base component; the fast-disassembly propeller comprises a seat body and a blade arranged on the seat body; the propeller base component comprises a fixed seat and a key switch; a clamping mechanism in detachable connection through rotation is arranged between the fixed seat and the seat body; the key switch is provided with a key body suitable for pressing touch and a key block fixed on the key body; multiple positioning structures corresponding to the key block when the seat body is in a clamping position are formed on the side of the seat body facing the fixed seat; and the key block is embedded into the positioning structure in a state without external force pressing and clamped between the fixed seat and the seat body, thus the peripheral movement of the fast-disassembly propeller is limited by the key block and a positioning slot, and such limitation is different from axial force limitation, therefore the mechanical strength is improved and an effect of good stability is realized.

Description

technical field [0001] The invention relates to the field of propellers, in particular to an aircraft and its propeller quick release device, a quick release propeller and a propeller base assembly. Background technique [0002] Propeller refers to a device that converts the rotational power of the engine into propulsion by rotating the blades in the air or water. There may be two or more blades connected to the base, and the rear side of the blades is a helical surface or similar to A propulsion device of a helicoid, which is widely used in aircraft. At present, the propeller structure of a common aircraft generally includes a base body and blades installed on the base body, wherein the base body is connected to the rotating shaft of the engine, and the rotating shaft rotates under the action of the power machine to drive the blades to rotate together, thereby pushing the aircraft to fly . For small detachable aircraft, usually between the seat body and the rotating shaft...
