[0006] Furthermore, the propeller mechanism includes a propeller motor, a propeller frame and propeller blades, the propeller motor is fixedly connected to one end of the wing arm, the driving end of the propeller motor is fixedly connected to the propeller frame, and the outer side of the propeller frame is fixedly connected to the propeller blades.

[0007] Furthermore, the camera structure includes a camera stand and a camera, the camera stand is fixedly connected to the bottom of the drone body, and the camera is movably connected to the inner side of the camera stand.

[0008] Furthermore, four adjustment racks are provided, and the four adjustment racks are symmetrically arranged in pairs on both sides of the drone body, and the two sides of the drone body are movably connected to the wing arms through the adjustment racks and bolts.

[0009] Furthermore, four locking frames are provided, the four locking frames are identical in size and shape, and the four locking frames are symmetrically arranged in pairs.

[0010] Furthermore, the bottom of the loading frame is fixedly connected with a supporting leg, and four supporting legs are provided. The four supporting legs are respectively located at the four corners of the bottom of the loading frame.

[0011] The beneficial effects of the present invention are as follows: through the provision of the first locking rod, the second locking rod, the locking frame and the telescopic spring, when installing the cargo rack, the staff holds the pull rod and then pulls the pull rod backward, the pull rod drives the sliding locking rod to move toward the back of the first locking rod and the second locking rod, and at the same time the telescopic spring on the sliding locking rod will shrink, and at the same time the locking frame will move out of the locking mouth on the first locking rod and shrink into the first sliding groove of the second locking rod. Then the staff places the drone body above the cargo frame and places the wing arm of the drone body between the first locking rod and the second locking rod so that the wing arm fits on the sliding locking rod. Then the staff releases the sliding locking rod, and the telescopic spring uses its own elasticity to push the extrusion plate to drive the sliding locking rod to move forward, and at the same time the locking frame will be inserted into the locking mouth of the first locking rod, thus completing the installation. At the same time, when disassembling, it only needs to be completed in the reverse order. This method is simple in installation and disassembly steps when installing and disassembling the cargo rack, thereby facilitating the installation and disassembly of the cargo rack and shortening the installation and disassembly time of the cargo rack.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 and Figure 4 The utility model provides a technical solution: an external cargo rack for a drone, comprising a cargo frame 11, a first locking rod 9 and a second locking rod 10 are fixedly connected to the top of the cargo frame 11, a movable groove 901 and a lock port 902 are respectively opened on one side of the first locking rod 9, a first sliding groove 1001 and a second sliding groove 1002 are respectively opened on one side of the second locking rod 10, the first locking rod 9 and the second locking rod 10 are movably connected to a sliding locking rod 13 through the movable groove 901 and the second sliding groove 1002, and one end of the sliding locking rod 13 A pull rod 15 is fixedly connected, the other end of the sliding lock rod 13 is fixedly connected to an extrusion plate 16, the other end of the sliding lock rod 13 is movably connected to a telescopic spring 17 on the outside, the top of the sliding lock rod 13 is fixedly connected to a lock frame 14, and a wing arm 5 is movably connected between the first lock rod 9 and the second lock rod 10. One end of the wing arm 5 is fixedly connected to a propeller mechanism, and the other end of the wing arm 5 is movably connected to an adjustment frame 4, one side of the adjustment frame 4 is fixedly connected to the drone body 1, and the bottom of the drone body 1 is fixedly connected to a camera mechanism.

[0020] Specific implementation: The propeller mechanism includes a propeller motor 6, a propeller frame 7 and a propeller blade 8. The propeller motor 6 is fixedly connected to one end of the wing arm 5. The driving end of the propeller motor 6 is fixedly connected to the propeller frame 7. The outer side of the propeller frame 7 is fixedly connected to the propeller blade 8. The propeller frame 7 and the propeller blade 8 are driven to rotate by the propeller motor 6, so that the drone body 1 can rise and fall and fly normally.

[0021] Specific implementation: The camera structure includes a camera frame 2 and a camera 3. The camera frame 2 is fixedly connected to the bottom of the drone body 1. The camera 3 is movably connected to the inner side of the camera frame 2. The camera 3 can be used for shooting, and the camera frame 2 facilitates the adjustment of the direction of the camera 3.

[0022] Specific implementation: There are four adjustment frames 4, which are symmetrically arranged on both sides of the drone body 1. The two sides of the drone body 1 are movably connected to the wing arms 5 through the adjustment frames 4 and bolts, and the adjustment frames 4 make it convenient for staff to fold the wing arms 5.

[0023] Specific implementation: There are four locking frames 14, and the four locking frames 14 are the same in size and shape. The four locking frames 14 are symmetrically arranged in pairs. By loosening the sliding locking rod 13, the telescopic spring 17 uses its own elasticity to push the extrusion plate 16 to drive the sliding locking rod 13 to move forward. At the same time, the locking frame 14 will be inserted into the locking port 902 of the first locking rod 9, thereby locking the wing arm 5.

[0024] Specific implementation: The bottom of the loading frame 11 is fixedly connected with a support leg 12, and there are four support legs 12. The four support legs 12 are respectively located at the four corners of the bottom of the loading frame 11, so that the drone body 1 can be placed more stably when installed on the loading frame 11.

[0025] Working principle: When installing the cargo rack, the staff holds the pull rod 15 and then pulls the pull rod 15 backward. The pull rod 15 drives the sliding lock rod 13 to move toward the back of the first lock rod 9 and the second lock rod 10. At the same time, the telescopic spring 17 on the sliding lock rod 13 will shrink. At the same time, the lock frame 14 will move out of the lock port 902 on the first lock rod 9 and shrink into the first slide groove 1001 of the second lock rod 10. Then the staff places the drone body 1 above the cargo frame 11 and places the wing arm 5 of the drone body 1 between the first lock rod 9 and the second lock rod 10 so that the wing arm 5 fits on the sliding lock rod 13. Then the staff releases the sliding lock rod 13, and the telescopic spring 17 uses its own elasticity to push the extrusion plate 16 to drive the sliding lock rod 13 to move forward. At the same time, the lock frame 14 will be inserted into the lock port 902 of the first lock rod 9, thus completing the installation. At the same time, when disassembling, you only need to follow the reverse order to complete the disassembly.

[0026] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
