The horn 3 is installed on the fuselage 4 through the folding component 2, the motor 1 is installed on the end of the horn 3, the rotary wing 5 is driven to rotate through the motor 1;
the folding member 2 comprises an outer section 21, an inner section 22 and a pin 23 which can be folded and unfolded mutually; the outer section 21 and the inner section 22 can rotate around the pin shaft 23 to realize the folding of the horn 3; when the axes of the outer section 21 and the inner section 22 are in the coincident state, the horn 3 is in the fully extended state.
The folding anti-loosening member 6 comprises a sleeve 61, and the sleeve 61 can be sleeved outside the outer section 21 and the inner section 22 under the condition that the axes of the outer section 21 and the inner section 22 are in a superposed state.
Because of the tolerance of the machined parts, a certain gap is left between the sleeve 61 of the anti-loosening folding member 6 and the body 4 in order to further ensure that the sleeve 61 of the anti-loosening folding member 6 can be tightened. In the present application, the existence of the gap between the sleeve 61 and the body 4 is fully utilized, the gasket 62 is sleeved on the outer part of the inner section 4, and the sleeve 61 is rotated and simultaneously can press the gasket 62 to be tightly attached to the body 4 (as shown in fig. 3).
In order to more clearly explain the anti-loose and locking function achieved by the folding and anti-loose member 6 of the present application, the following description is made in conjunction with the structures of the folding member 2 and the folding and anti-loose member 6:
as shown in fig. 4 to 8, the folding check member 6 includes a hollow sleeve 61 and a washer 62, and the sleeve 61 has a threaded portion and a sliding surface portion inside.
The folding member 2 comprises an outer section 21, an inner section 22 and a pin 23. The outer section 21 and the inner section 22 are rotatable about the axis of the fastener 23; when the axes of the outer section 21 and the inner section 22 coincide, the sleeve 61 of the folding anti-loosening member 6 can be sleeved outside the joint part of the outer section 21 and the inner section 22, and the gasket 62 is tightly pressed to be attached to the machine body 4 through screwing in matching with the threads of the outer section 21 or the inner section 22.
The outer section 21 comprises a first shaft section 211, a collar 212 and a second shaft section 213 connected in series. The collar 212 has a larger outer diameter than the first shaft section 211 and the second shaft section 213. The first shaft section 211 is provided with a radial through hole, and the horn 3 and the second shaft section are riveted through the radial through hole; the outer periphery of the collar 212 is smooth and is fitted with a smooth surface portion inside the sleeve 61 of the folding check member 6; the second shaft section 213 is milled with a groove along the axial direction, and milled with an upper plane and a lower plane along the radial direction, and the upper plane, the lower plane and the groove form two ear plates together, and the ear plates are provided with through holes for passing through the pin 23.
The inner section 22 is composed of a threaded shaft section 221, an optical axis section 222 and a connecting plate 223. The threaded shaft section 221 and the optical axis section 222 are connected in sequence, and the diameter of the threaded shaft section 221 is larger than that of the optical axis section 222. The threaded shaft section 221 has an external thread that mates with a threaded portion inside the sleeve 61 of the fold prevention member 6.

The optical axis section 222 is radially provided with a through hole, and the optical axis section 222 is fixed with the machine body 4 through the through hole by using a bolt, so that the axial movement and the rotation of the optical axis section can be limited.
After the folding member 2 is unfolded, the screw part of the sleeve 61 of the folding anti-loosening member 6 is matched with the external thread of the inner section 22, and the sliding surface part on the sleeve of the folding anti-loosening member 6 is screwed until the sliding surface part is contacted with the collar 212 on the outer section 21, so that the outer section 21 and the inner section 22 cannot rotate relatively around the axis of the pin 23, and the locking after the machine arm is unfolded is realized.
The working principle of the application is as follows:
because the vibration that unmanned aerial vehicle produced in flight can make the nut of round pin axle 23 between outer section 21 and the interior section 22 take place to become flexible, and then lead to producing the gap between the slide face part of sleeve 61 and the axle collar of outer section 21, and then lead to outer section 21 can rotate around the relative interior section 22 of axis of round pin axle 23, and then lead to the not hard up of sleeve 61, the relative fuselage of horn is unstable can bring danger for unmanned aerial vehicle in flight, so necessary take measures to prevent sleeve 61 from appearing the not hard up phenomenon in unmanned aerial vehicle flight.
When the folding member 2 is in use, the inner section 22 is fixed to the body 4, and because there are certain tolerances in the parts, a certain gap is left between the sleeve 61 and the body 4 in order to ensure that the sleeve 61 can be tightened. With the presence of the gap, a washer 62 is fitted over the inner segment 22. The inner diameter of washer 62 is smaller than the outer diameter of the washer-receiving portion of inner section 22 to ensure that friction will occur between washer 62 and inner section 22 when installed.
In order to further improve the anti-loosening effect, the outer diameter of the washer 62 is at least larger than the inner diameter of the threaded portion on the sleeve 61 plus 2 times of the thread height, and the thickness of the washer 62 is larger than the gap between the sleeve 61 and the machine body 4, so that the washer 62 is squeezed after the inner section 22 is screwed down, friction force is generated between the washer 62 and the sleeve 61, the sleeve 61 can be placed to rotate, and the anti-loosening effect is achieved.
In order to further increase the loosening effect, an annular groove is provided in the end face of the sleeve 61, into which a portion of the washer 62 can be snapped, and the thickness of the washer 62 is greater than the sum of the gap between the sleeve 61 and the body 4 and the depth of the annular groove.
The utility model also provides a folding locking component of horn, its concrete structure is the same with the structure of the folding locking component among the above-mentioned unmanned aerial vehicle, here no longer describes tiredly.
The above description is only the application embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and the right scope of the present invention cannot be limited thereby, and any equivalent changes made according to the technical solution of the present invention should be covered within the protection scope of the present invention.
