Background

At present unmanned aerial vehicle's motor shaft's connected mode most is done annular knurl, optical axis or is flat position, is connected with the motor protecgulum, and such connected mode uses for a long time, and then the motor shaft skids easily with the protecgulum, leads to motor trouble. At present, the locking mode of the shaft of the unmanned aerial vehicle is mainly locking through a clamp spring and an additional screw or directly locking through one screw, and a nut locking mode is also used, so that the shaft of the unmanned aerial vehicle can be loosened after being used for a long time, and the motor is in a fault state.

SUMMERY OF THE UTILITY MODEL

In order to overcome the shortcomings of the prior art, the utility model aims to provide a connecting shaft for unmanned aerial vehicle's motor.

In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a connecting axle for on unmanned aerial vehicle's motor, includes cylindric body, is equipped with the bulge loop along its radial on the body outer wall, is equipped with many sand grips that are parallel to each other along its radial on the outer wall of bulge loop, sand grip and body axial direction parallel. An axial hole is arranged in the body; the convex ring is fixedly arranged on the outer wall of the body, a plurality of convex strips which are parallel to each other are arranged on the outer wall of the convex ring along the radial direction of the convex ring, namely, the structure formed by the convex ring and the convex strips is in a gear shape, when the connecting shaft is connected with the front cover of the motor, the convex ring and the convex strips are pressed into the front cover through external force, and at the moment, the convex strips are embedded in the front cover, so that the problem that the front cover and the connecting shaft are connected and then slip between the front cover and the connecting shaft when the front cover; generally, the material of the connecting shaft is harder than that of the front cover, so that the gear-shaped structure on the connecting shaft is easily pressed into the front cover by adopting the existing process.

Preferably, the convex ring and the body are integrally formed, and the convex strip and the convex ring are integrally formed. Namely, the body of the connecting shaft, the convex ring and the convex strip are processed on the same metal material.

Preferably, the intervals between two adjacent convex strips are equal, and the cross sections of the convex strips are trapezoidal. Namely, a plurality of convex strips are uniformly arranged on the outer wall of the convex ring, and the structure formed by the convex ring and the convex strips is in a gear shape.

Further, an external thread is arranged on the outer wall of a connecting end, connected with the motor, of the body, a connecting hole communicated with the axial hole is formed in the connecting end, and an internal thread is arranged on the inner wall of the connecting hole; the external thread and the internal thread rotate in opposite directions.

The beneficial technical effects are as follows: by adopting the structure of the utility model, when the motor front cover is connected, the convex ring and the convex strips are pressed into the front cover through external force, at the moment, each convex strip is embedded in the front cover, which is beneficial to solving the problem that the front cover slips between the front cover and the connecting shaft after being connected and when being used for a long time; set up external screw thread and internal thread that direction of rotation is opposite on body coupling end, when being connected with the motor, the external screw thread of link locks simultaneously with the corresponding structure on the internal thread motor, is favorable to preventing that connecting axle and motor pine from taking off.

Detailed Description

In order to make the technical field of the present invention better understand, the present invention is further described in detail with reference to the accompanying drawings and embodiments.

As shown in fig. 1-2, the embodiment of the utility model provides a connecting shaft, it is used for unmanned aerial vehicle's motor on, the connecting shaft includes cylindric body 1, radially is equipped with bulge loop 2 along it on the body outer wall, radially is equipped with many sand grips 3 that are parallel to each other along it on the outer wall of bulge loop, sand grip 3 and body axial direction parallel.

Specifically, the convex ring 2 and the body 1 are integrally formed, and the convex strip 3 and the convex ring 2 are integrally formed. Namely, the body 1 of the connecting shaft, the convex ring 2 and the convex strip 3 are processed on the same metal material.

Preferably, the intervals between two adjacent convex strips 3 are equal, and the cross section of each convex strip 3 is trapezoidal. Many sand grips 3 evenly set up on the bulge loop 2 outer wall promptly, and the overall structure that bulge loop 2 and sand grip 3 are constituteed is the gear form.

As shown in fig. 3, an axial hole 101 is provided in the body 1; the convex ring 2 is fixedly arranged on the outer wall of the body 1, a plurality of convex strips 3 which are parallel to each other are arranged on the outer wall of the convex ring 2 along the radial direction of the convex ring 2, namely, the integral structure formed by the convex ring 2 and the convex strips 3 is in a gear shape, when the connecting shaft is connected with the front cover of the motor, the convex ring 2 and the convex strips 3 are pressed into the front cover through external force, at the moment, the convex strips 3 are embedded in the front cover, and the problem that the front cover slips between the front cover and the connecting shaft after being connected and when being used for a long time is favorably solved; generally, the material of the connecting shaft is harder than that of the front cover, so that the gear-shaped structure on the connecting shaft is easily pressed into the front cover by adopting the existing process.

As shown in fig. 2-3, an external thread 4 is arranged on the outer wall of the connecting end of the body 1 connected with the motor, a connecting hole communicated with the axial hole 101 is arranged in the connecting end, and an internal thread 5 is arranged on the inner wall of the connecting hole; the male thread 4 is rotated in the opposite direction to the female thread 5. For example, the external thread 4 processed on the outer wall of the connecting end is processed into a reverse-rotation thread, the internal thread 5 processed on the inner wall of the connecting hole is a forward-rotation thread, and vice versa; the locking after the connecting shaft is connected with the motor is ensured by utilizing a positive thread and a negative thread, so that the motor is prevented from being failed due to the failure of a locking mode.

In the above description, it should be noted that the terms "mounted," "connected," and the like are used in a broad sense, and for example, they may be fixedly connected, detachably connected, or integrally connected; the connection may be direct or indirect via an intermediate medium, and the connection may be internal to the two components.
