Problems solved by technology

[0004] Obviously, the above-mentioned traditional disadvantages of the prior art: the quick disassembly structure (that is, the buckle assembly structure composed of metal shrapnel, etc.) only relies on the elastic force of the metal shrapnel to block the propeller, and the propeller is not locked on the motor. When the motor speed changes from high to low, the propeller speed may be greater than the motor speed for an instant, and at this time there will be a danger of the propeller falling off

Abstract

The invention discloses a self-locking mechanism for fast disassembly and assembly of a propeller. The self-locking mechanism comprises the propeller, propeller installing devices, self-locking pin shafts, self-locking pin shaft caps, embedded matching parts and return springs. The self-locking mechanism provided by the invention has the technical advantages of flexible operation, faster and more convenient disassembly and assembly, firmer locking mode and stronger stability and the like.

Description

technical field [0001] The invention relates to the technical field of propeller aircraft, in particular, a self-locking mechanism for fast disassembly and assembly of a propeller is designed. Background technique [0002] With the improvement of people's living standards and the rapid development of science and technology, more and more propeller aircraft (including manned aircraft and unmanned aircraft) have entered people's lives; [0003] At present, the propellers of most propeller aircrafts in the market are installed by means of screw fastening, but the disassembly and assembly speed is relatively slow and the disassembly and assembly efficiency is relatively low during disassembly and assembly of this connection method. In addition, with the development of propeller aircraft and meeting the requirements of quick disassembly and assembly, the propeller type of the latest multi-axis drone produced by a certain company can be quickly replaced and disassembled by means o...
