Abstract

The invention discloses an embedded quick-opening propeller seat. A fixed clamping seat is mounted on the upper surface of a motor upper cover, a flange plate is arranged at the bottom of the fixed clamping seat, a shaft hole is formed in the middle of one surface of the flange plate, clamping blocks are arranged on the periphery of the shaft hole symmetrically, and a notch is formed between the clamping blocks. A fixing shaft is mounted in the shaft hole and penetrates through a spring and a press-push piece, and a clamping ring is mounted at the end of the fixing shaft. A through hole is formed in the middle of a screw propeller, a clamping groove matched with the clamping blocks on the fixed clamping seat is formed in one end of a movable clamping seat, and the screw propeller is connected with the fixed clamping seat of the motor upper cover through the movable clamping seat. The embedded quick-opening propeller seat has the advantages that the previous remaining problem of requiring arrangement of different propeller seats for contra-rotating propellers is solved, and circumferential registering of the upper cover and a base provides highest concentricity; the embedded quick-opening propeller seat is free to mount and demount, convenient and reliable; varieties of accessories are decreased and universality is enhanced.

Description

technical field [0001] The invention relates to the blade technology of an unmanned aerial vehicle, in particular to an inter-embedded quick-opening paddle seat. Background technique [0002] At present, the paddle seat of the UAV blade on the market is divided into a fixed paddle seat structure and a spinning paddle seat structure. Fixed propeller seat structure: first fix the propeller seat on the motor with four screws (or the appropriate mounting holes of the motor itself, no propeller seat is required), and then fix the propeller on the propeller seat (motor) with four screws through the pressure plate superior. This type of slurry seat structure requires frequent assembly and disassembly of a large number of screws every time it is installed and used, which is time-consuming and labor-intensive, and the threads will slip after repeated use for a long time. At the same time, because there is no clear positioning point, whether the propeller and the motor are concentri...
