[0029] Please see Figures 1-5 A camera 5 for a drone that is easy to assemble includes a drone body 1. An assembly mechanism is located below the drone body 1. The assembly mechanism includes a connecting frame 2, a positioning frame 3, a fixing plate 4, a camera 5, a mounting shell 6, and a fixing mechanism. The connecting frame 2 is connected to the bottom surface of the drone body 1. The positioning frame 3 is installed at the bottom end of the connecting frame 2. The fixing plate 4 is fixed to the outside of the connecting frame 2. The camera 5 is inserted into the mounting shell 6, and the mounting shell 6 is inserted into the positioning frame 3. The fixing mechanism includes a rod 7, a fixing sleeve 8, a sleeve 9, a groove 10, a slider 11, a snap-fit ​​plate 12, a slot 13, and a sliding... The device includes a groove 14, a sliding sleeve 15, a push ring 16, and a limiting mechanism. The insertion rod 7 is inserted into the fixed plate 4 and the mounting shell 6. The fixed sleeve 8 is set at the top of the insertion rod 7. The insertion sleeve 9 is fixed inside the fixed sleeve 8. Multiple sets of inclined grooves 10 are distributed on the inner wall of the fixed sleeve 8. The slider 11 slides in multiple sets of sliding grooves 14. The snap plate 12 is installed on the inner side of multiple sets of sliders 11. Multiple sets of snap grooves 13 are distributed on the outer wall of the insertion rod 7. Multiple sets of sliding grooves 14 are distributed on the outer wall of the fixed sleeve 8. The sliding sleeve 15 slides in multiple sets of sliding grooves 14. The push ring 16 is installed on the inner side of the sliding sleeve 15 and abuts against the bottom surface of multiple sets of sliding sleeves 15.

[0030] The limiting mechanism includes a connecting sleeve 17, a limiting sleeve 18, a sliding rod 19, a limiting groove 20, a limiting block 21, and an unlocking groove 22. The connecting sleeve 17 is fixed to the top surface of the sliding sleeve 15, the limiting sleeve 18 rotates on the outer wall of the fixed sleeve 8, multiple sets of sliding rods 19 are provided on the top surface of the connecting sleeve 17, multiple sets of limiting grooves 20 are provided on the limiting sleeve 18 and are slidably connected to multiple sets of sliding rods 19 respectively, the limiting block 21 is installed on the top of multiple sets of sliding rods 19, and the unlocking groove 22 is provided at one end of multiple sets of limiting grooves 20.

[0031] The outer wall of the insertion rod 7 is provided with positioning strips 23, and multiple sets of positioning strips 23 are provided. The inner wall of the insertion sleeve 9 is provided with positioning grooves 24, and multiple sets of positioning grooves 24 are provided and are slidably connected to multiple sets of positioning strips 23 respectively. The sliding of the positioning strips 23 in the positioning grooves 24 can prevent relative rotation between the insertion rod 7 and the insertion sleeve 9.

[0032] Multiple sets of snap-fit ​​plates 12 are respectively installed at an angle inside multiple sets of sliders 11 and are adapted to multiple sets of snap-fit ​​slots 13. The angled snap-fit ​​plates 12 can generate a wedge effect when snapped into the snap-fit ​​slots 13, increasing the snap-fit ​​force.

[0033] The top surface of the push ring 16 is rounded and abuts against the bottom surfaces of multiple sets of sliders 11. The rounded corner design of the push ring 16 can reduce the frictional resistance with the bottom surfaces of the sliders 11, making the movement smoother.

[0034] A push spring 25 is installed on the bottom surface of the limiting sleeve 18, and a thrust bearing 26 is installed on the bottom surface of the push spring 25. The push spring 25 provides elastic support, and the thrust bearing 26 can reduce the friction when the limiting sleeve 18 rotates.

[0035] The diameter of each unlocking slot 22 is larger than that of the limiting block 21. The fact that the diameter of the unlocking slot 22 is larger than that of the limiting block 21 ensures that the limiting block 21 can pass smoothly during unlocking.

[0036] The multiple sets of limiting grooves 20 are all arc-shaped and are slidably connected to the multiple sets of slide rods 19 respectively. The arc-shaped limiting grooves 20 can guide the slide rods 19 to move along a smooth trajectory and avoid jamming.

[0037] In this embodiment, when it is necessary to splice the camera 5 and the drone body 1, the camera 5 is snapped into the mounting shell 6, and then the mounting shell 6 is snapped into the positioning frame 3. Then, the plug rod 7 is inserted into the fixing plate 4 and the mounting shell 6, and then the fixing sleeve 8 is inserted into the plug rod 7. The positioning is then inserted into the positioning groove 24 through multiple sets of positioning strips 23. Then, the sliding sleeve 15 is pushed to slide along the sliding groove 14 and the push spring 25 is squeezed through the connecting sleeve 17. The bottom surface of multiple sets of sliders 11 is pushed through the push ring 16. The multiple sets of sliders 11 slide along the inclined groove 10 and drive multiple sets of snap-fit ​​plates 12 to snap into the slot 13. At the same time, multiple sets of sliding rods 19 are inserted into the unlocking groove 22. The rotating limiting sleeve 18 rotates so that the multiple sets of sliding rods 19 slide in the limiting groove 20. The sliding sleeve 15 is limited by the contact between the multiple sets of limiting blocks 21 and the top surface of the limiting sleeve 18.

[0038] More specifically, when disassembly is required, rotating the rotating sleeve causes multiple sets of sliding rods 19 to slide along the limiting groove 20, causing multiple sets of sliding rods 19 to move into the unlocking groove 22, causing multiple sets of limiting blocks 21 to release their contact with the top surface of the limiting sleeve 18, and pushing the connecting sleeve 17 and the sliding sleeve 15 to slide along the sliding groove 14 through the push spring 25, while driving the push ring 16 to release its contact with multiple sets of sliders 11. Then, multiple sets of sliders 11 slide outward along the inclined groove 10, causing multiple sets of snap-fit ​​plates 12 to disengage from the snap-fit ​​groove 13, releasing the snap-fit ​​of the plug rod 7, and then separating the fixing sleeve 8 from the plug rod 7, thus completing the disassembly of the camera 5.

[0039] In summary, when the overall equipment is in use or operation: when it is necessary to splice the camera 5 and the drone body 1, the camera 5 is snapped into the mounting shell 6, then the mounting shell 6 is snapped into the positioning frame 3, then the plug rod 7 is inserted into the fixing plate 4 and the mounting shell 6, then the fixing sleeve 8 is inserted into the plug rod 7, and the positioning strips 23 are positioned and inserted into the positioning grooves 24. Then, the sliding sleeve 15 is pushed to slide along the sliding groove 14 and the push spring 25 is squeezed by the connecting sleeve 17. The bottom surface of the multiple sliding blocks 11 is pushed by the push ring 16. The multiple sliding blocks 11 slide along the inclined groove 10 and drive the multiple snap-fit ​​plates 12 to snap into the slot 13. At the same time, the multiple sliding rods 19 are inserted into the unlocking groove 22. The rotating limiting sleeve 18 rotates so that the multiple sliding rods 19 slide in the limiting groove 20. The sliding sleeve 15 is limited by the contact between the multiple limiting blocks 21 and the top surface of the limiting sleeve 18.

[0040] When disassembly is required, rotating the rotating sleeve causes multiple sets of sliding rods 19 to slide along the limiting groove 20, moving the multiple sets of sliding rods 19 into the unlocking groove 22, causing the multiple sets of limiting blocks 21 to release their contact with the top surface of the limiting sleeve 18. The push spring 25 pushes the connecting sleeve 17 and the sliding sleeve 15 to slide along the sliding groove 14, while simultaneously driving the push ring 16 to release its contact with the multiple sets of sliders 11. Then, the multiple sets of sliders 11 slide outward along the inclined groove 10, causing the multiple sets of snap-fit ​​plates 12 to disengage from the snap-fit ​​groove 13, releasing the snap-fit ​​of the insertion rod 7. Then, the fixing sleeve 8 is separated from the insertion rod 7, thus completing the disassembly of the camera 5.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
