Problems solved by technology

[0004] Obviously, the above-mentioned traditional shortcomings of the prior art: 1. 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 in the motor. In the process of changing the motor speed from high to low, the propeller speed may be greater than the motor speed for a moment, and at this time there will be a danger of the propeller falling off
2. At the same time, the quick disassembly and assembly structure requires a special propeller to match it (that is, only a special propeller can form a snap-fit ​​method), and it is not compatible with other propellers for installation; however, at the current market price, this special propeller Propellers are very expensive to use

Abstract

The invention discloses a self-locking mechanism for rapid disassembly and assembly of a propeller, which comprises a propeller installation shaft and a self-locking assembly; a limit step is arranged in the middle of the propeller installation shaft; cavity, and the bottom of the propeller installation shaft forms a bushing; the top of the bushing wall at the bottom of the propeller installation shaft is also provided with a mounting hole or a mounting groove; the self-locking assembly includes a snap ring, a pressure spring, a self-locking Lock ring and insert fit. The self-locking mechanism for rapid disassembly and assembly of the propeller provided by the present invention has many technical advantages such as flexible operation, quicker and more convenient disassembly and assembly, firmer locking mode of the self-locking component, and stronger stability.

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...
