The unmanned aerial vehicle frame includes main frame and screw, and the screw is generally through horn and main frame fixed connection, because the screw is according to flying the certain little inclination of accuse demand and personally submitting with the level when setting up, and screw and horn are the vulnerable part moreover. At present, the propellers and the horn are generally arranged and fixed when leaving a factory, manual calibration is needed when the inclination angle of the propeller is set, the time is long, the precision difference of the inclination angles of the four propellers is large, the flight control and the flight stability can be affected, and the installation requirement is high, so that the assembly is not convenient.

Disclosure of Invention

Not enough to prior art, the utility model provides a horn for unmanned aerial vehicle.

The utility model provides a horn for unmanned aerial vehicle, includes the rectangular shape body that the level set up, its characterized in that: a positioning surface is arranged at the end part of the inner end of the pipe body, and the positioning surface is parallel to the axial direction of the pipe body; and limiting blocks are fixedly arranged on two sides of the end part of the outer end of the pipe body.

The utility model discloses a theory of operation: the pipe body realizes angle positioning installation when being installed on the main frame through the positioning surface, and the propeller is provided with a motor shaft and realizes installation of a fixed inclination angle when being fixed on the pipe body through a limiting block.

Further comprises the following steps: a first fixing sleeve is fixedly sleeved on the pipe body at a position corresponding to the positioning surface, and the positioning surface is positioned on the first fixing sleeve; a second fixing sleeve is fixedly sleeved on the pipe body at a position corresponding to the limiting block, and the limiting block is positioned on the second fixing sleeve; is convenient for processing and assembling.

Further comprises the following steps: and a convex block is integrally arranged on one side of the first fixing sleeve, and the outer end surface of the convex block is the positioning surface.

Further comprises the following steps: the limiting blocks and the outer walls of the two sides of the second fixing sleeve are integrally arranged, so that the processing and the assembly are convenient.

Further comprises the following steps: the up end of stopper all be located the coplanar and with the axial parallel arrangement of body, the up end of stopper be the stationary plane be used for with screw motor shaft fixed connection, this kind of structure atress is more balanced.

Further, an included angle is formed between the upper end face of the limiting block and the horizontal plane, and the included angle ranges from 3 degrees to ~ 6 degrees.

Further comprises the following steps: and the limiting block is provided with a vertical threaded through hole.

The utility model has the advantages that: the angle positioning installation is realized when the pipe body is installed on the main frame through the positioning surface, the installation of a fixed inclination angle is realized when the propeller setting motor shaft is fixed on the pipe body through the limiting block, so that the machine arm is installed on the main frame at a fixed angle, and meanwhile, the propeller motor shaft can be quickly installed on the machine arm in an inclined manner, so that the assembly of the machine arm and the propeller becomes convenient and quick; the fixed sleeve is fixedly sleeved on the machine arm, and the corresponding positioning piece is arranged on the fixed sleeve, so that the structure is simple and the processing is easy.
