Problems solved by technology

At present, the propeller mainly relies on the propeller cap to fix it on the motor shaft, but due to the high speed of the propeller and the motor, the vibration of the body during the movement is very large, which may lead to loosening or damage of the thread, and eventually lead to an accident of the body
In addition, when removing and installing the propeller, the operation is inconvenient, and it is easy to cause damage to the thread, making the connection between the propeller and the motor less tight, and increasing the risk of accidents

Embodiment 1

[0038] Please refer to figure 1 as well as figure 2 , Embodiment 1 of the present invention is: a fixed propeller assembly used on a drone, which can provide power for the drone. The fixed paddle assembly includes a paddle 1 , buckles, a spring 4 , a spring shaft 5 , a base 7 and a motor 9 in sequence. Such as image 3 As shown, the paddle 1 includes a paddle 11 and a paddle connecting seat 12 integrally formed with the paddle 11. A pair of hooks 13 are respectively provided on both sides of the bottom of the paddle connecting seat 12. The buckle includes The first buckle 2 and the second buckle 3 , and the two pairs of hooks 13 cooperate with the first buckle 2 and the second buckle 3 respectively. The hook 13 includes a clamping end, and the inner side of the clamping end is an inclined surface. The first buckle 2 and the second buckle 3 are movably arranged on the base 7, and the inner sides of the first buckle 2 and the second buckle 3 are oppositely arranged; as Fi...

Abstract

The invention discloses a fixed oar assembly, which comprises an oar, a first buckle, a second buckle, a spring, a pedestal and a motor. The oar consists of blades and a blade connecting seat integrated to the blades. Both sides of the blade connecting seat are respectively equipped with a pair of hooks, and the two pairs of hooks cooperate with the first buckle and the second buckle respectively. The first buckle and the second buckle are movably arranged on the pedestal, and the spring abuts between the first buckle and the second buckle. The pedestal and the motor are in fastened connection. The fixed oar assembly has a compact structure, when the hooks of the blade connecting seat are clamped between the first buckle and the second buckle, the spring can provide elastic force to maintain firm clamping connection between the hooks and the first buckle and the second buckle, so that loosening cannot occur during flight. When the oar needs to be taken off, only by compressing the spring, the first buckle and the second buckle can break away from the hooks, and disassembly is very convenient.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a fixed propeller assembly. Background technique [0002] At present, UAV technology is developing rapidly, and it has been used more and more because of its advantages of portability, ease of use, and flexible operation. As the main power source of the UAV, the blade assembly bears most of the load of the airframe. At present, the propeller mainly relies on the propeller cap to fix it on the motor shaft, but due to the high speed of the propeller and the motor, the vibration of the body during the movement is very large, which may lead to loosening or damage of the thread, and eventually lead to an accident of the body. In addition, when disassembling and installing the propeller, the operation is inconvenient, and it is easy to cause damage to the thread, making the connection between the propeller and the motor less tight, and increasing the risk of accidents. In order to r...
