Problems solved by technology

Most of the propellers in the prior art are fixed on the propeller clamp with screws, and the thread fastening glue is applied to prevent loosening. During use, due to factors such as vibration caused by the high speed of the propeller, the thread fastening glue has the risk of failure. After failure, the screw It is easy to loosen, and in severe cases, it may even cause the propeller to separate and cause a flight accident; in normal duty, the thread fastening glue makes it difficult to disassemble when replacing the propeller, and sometimes even requires partial heating to disassemble, and multiple disassembly is easy to damage the thread, reducing the reliability of the connection sex

Embodiment 1

[0035] Please refer to figure 1 , a paddle clip provided by the embodiment of the present invention includes a paddle base 2, a paddle cover 1 arranged on the paddle base 2, and an elastic member 4 arranged between the paddle base 2 and the paddle cover 1 through a connecting mechanism, and also includes a limit organization,

[0036] The connecting mechanism includes a first connecting hole 13 arranged in the middle of the elastic member 4 and a connecting piece 5 arranged on the paddle seat 2 to fit the first connecting hole 13;

[0037] The limiting mechanism includes a limiting groove 7 arranged at the end of the elastic member 4 and a limiting member 3 arranged on the oar seat 2 and matched with the limiting groove 7 .

[0038] As mentioned in the background technology, most of the current propellers are fixed on the propeller clamp by screws, and the thread fastening glue is applied to prevent loosening. During use, due to factors such as vibration caused by the high sp...

Embodiment 2

[0043] The same features of this embodiment and Embodiment 1 will not be repeated. The difference between this embodiment and Embodiment 1 is that: the limiting member 3 includes a rod member and a card slot 6 opened in the radial direction, and the limiting groove 7 is adapted to the card slot 6, so that the elastic member 4 can be limited in the card slot 6 when the paddle clamp 10 rotates.

Embodiment 3

[0045] The features of this embodiment that are the same as those of Embodiment 2 will not be described in detail here. The difference between this embodiment and Embodiment 2 is that: the limiting member 3 is a threaded limiting member, and the card slot 6 is opened on the threaded limiting member. on the screw of the piece.

[0046] The thread limiter is easy to assemble and disassemble, can be used repeatedly, and is tightly connected. The upper end of the threaded connector can be provided with an anti-falling head. In addition, the head can be provided with a cross groove or a slot, which also effectively avoids the limit. The spacer 3 is loosened from the upper part of the paddle cover 1, and the setting of different groove types facilitates the installation of the spacer 3 with different tools. Here, it is not limited to a straight groove and a cross groove, but other groove types are also possible.

Abstract

The invention discloses a propeller clamp and a foldable propeller and relates to the field of unmanned aerial vehicles. The propeller clamp comprises a propeller seat, a propeller cover arranged on the propeller seat and an elastic piece arranged between the propeller seat and the propeller cover through a connecting mechanism and further comprises a limiting mechanism, the connecting mechanism comprises a connecting hole formed in the middle portion of the elastic piece and a connecting piece arranged on the propeller seat and matched with the connecting hole; and the limiting mechanism comprises limiting grooves formed in the tail ends of the elastic piece and limiting pieces arranged on the propeller seat and matched with the limiting grooves. An integrated spring leaf anti-loosening measure is adopted by the propeller clamp, screws can be effectively prevented from being loosened, anti-loosening operation is reliable, detachment and installation are easy, maintenance is easy, andan unmanned aerial vehicle propeller is convenient to replace and can be reused.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a paddle clip and folding paddle. Background technique [0002] The propeller assembly on the drone is a key component of the drone. The propeller is used to convert the rotation of the motor or engine shaft of the drone into thrust or lift, and it is connected to the motor or the engine through the paddle clamp. Most of the propellers in the prior art are fixed on the propeller clamp with screws, and the thread fastening glue is applied to prevent loosening. During use, due to factors such as vibration caused by the high speed of the propeller, the thread fastening glue has the risk of failure. After failure, the screw It is easy to loosen, and in severe cases, it may even cause the propeller to separate and cause a flight accident; in normal duty, the thread fastening glue makes it difficult to disassemble when replacing the propeller, and sometimes even requires partial...
