The direction of the screw thread is opposite to the rotation direction of the propeller, and the screw thread is tighter and tighter.
For realizing above-mentioned purpose, design an unmanned aerial vehicle screw quick detach device, including rotating electrical machines, screw blade, connecting plate, bolt and gasket, its characterized in that: the upper end of the rotating motor is connected with a lower connecting module, the lower connecting module is connected with the upper connecting module through threads, and the left end and the right end of the upper connecting module are connected with propeller blades through bolts and gaskets; the bolts and the gaskets on the left side and the right side are connected through a connecting plate.
The lower connecting module is of a cylindrical structure, a threaded structure is arranged on the outer edge of the cylinder of the lower connecting module, and a connecting shaft is connected and arranged in the center of the top of the lower connecting module.
The upper connecting module is of a convex structure, the middle part of the upper connecting module is of a cylindrical structure, a cylindrical groove is formed in the lower end of the middle part of the upper connecting module, and internal threads matched with the threads on the outer side of the lower connecting module are arranged in the cylindrical groove; the left side and the right side of the upper connecting module connected with the middle cylinder are respectively provided with a connecting module connected with the end part of the propeller blade, and the connecting modules are of a disc-shaped structure.
The connecting shaft penetrates through the upper connecting module and the connecting plate from bottom to top and is positioned above the connecting plate.
And the bolts in the bolts and the gaskets respectively penetrate through the end parts of the connecting plate and the propeller blade from top to bottom and are connected with the connecting module of the upper connecting module.
Compared with the prior art, the utility model, a provide an unmanned aerial vehicle screw quick detach device uses threaded connection to replace screwed connection, only needs to screw and loosen the screw, can accomplish to install and remove, reduces to install and remove the degree of difficulty. The direction of the screw thread is opposite to the rotation direction of the propeller, and the screw thread is tighter and tighter.

Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 5, the upper end of the rotating electrical machine 1 is connected with a lower connecting module 2, the lower connecting module 2 is connected with an upper connecting module 3 through threads, and the left and right ends of the upper connecting module 3 are connected with propeller blades 4 through bolts and gaskets 6; the bolts and the gaskets 6 on the left side and the right side are connected through a connecting plate 5.
The lower connecting module 2 is of a cylindrical structure, the outer edge of the cylinder of the lower connecting module 2 is provided with a thread structure, and the center of the top of the lower connecting module 2 is provided with a connecting shaft 7 in a connecting mode.
The upper connecting module 3 is of a convex structure, the middle part of the upper connecting module 3 is of a cylindrical structure, a cylindrical groove is formed in the lower end of the middle part of the upper connecting module 3, and internal threads matched with the external threads of the lower connecting module 2 are arranged in the cylindrical groove; the left side and the right side of the upper connecting module 3 connected with the middle cylinder are respectively provided with a connecting module 8 connected with the end part of the propeller blade 4, and the connecting modules 8 are in a disc-shaped structure.
The connecting shaft 7 penetrates through the upper connecting module 3 and the connecting plate 5 from bottom to top and is located above the connecting plate 5.
The bolts in the bolts and the gaskets 6 respectively penetrate through the end parts of the connecting plate 5 and the propeller blades 4 from top to bottom and are connected with the connecting module 8 of the upper connecting module 3.
As shown in the above figure, the propeller is divided into an upper propeller and a lower rotating electric machine 1, which are connected by a screw.
The upper propeller is divided into two parts, namely propeller blades 4 at two sides and an upper connecting module 3 in the middle, and the two parts are fastened through bolts and gaskets 6. The inner side of the upper connecting module 3 is provided with an internal thread which is connected and screwed with the external thread of the lower connecting module 2 on the rotating motor 1 below.
The distance between the upper propeller and the lower rotating motor is shortened by the design of threaded connection, and the loss of torque force transmission of the rotating motor is reduced. And, the closer the propeller is to the motor, the more the radial shake can be reduced, and the effect of the propeller damping is achieved.
