Description

Technical Field

[0001] This utility model relates to the field of drone mounting technology, specifically to an emergency throwing component device for a double-ring hook used in drones. Background Technology

[0002] Equipment such as ammunition canisters can be mounted on the bottom of a drone platform via a mounting bracket. These canisters are typically arranged side-by-side and directly fixed to the bottom of the drone. In certain situations, these canisters or other equipment need to be ejected urgently, but existing mounting brackets cannot quickly eject them. Therefore, this invention proposes an emergency ejection device with a double-ring hook for drones. Utility Model Content

[0003] Technical problems to be solved

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an emergency throwing component device with a double-ring hook for use with drones.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: an emergency throwing component device for a double-ring hook used in drones, comprising a main frame, a hanging rod fixedly connected to the top of the main frame and fixedly connected to the drone, a hanging groove provided at the bottom of the main frame, a movable first hook installed at the hanging groove, a locking assembly provided on one side of the main frame, the locking assembly including a fixing frame mounted on the main frame, a threaded hole provided on one side of the fixing frame, a second fixing frame fixedly installed at the bottom of the main frame, and a dual-axis motor fixedly installed inside the second fixing frame. The two output ends of the dual-axis motor are fixedly connected to transmission rods, and the transmission rods are connected to small gears. One side of the small gear is meshed with a large gear, and one side of the large gear is fixedly connected to a threaded column. The threaded column is threaded into the threaded hole of the fixing frame. During emergency throwing, the dual-axis motor drives the transmission rods to rotate, which in turn drives the small gear and the large gear to rotate, causing the threaded column to rotate in one direction and eventually disengage from the fixing frame. After the fixing frame disengages, the locking assembly falls off, allowing the object suspended by the locking assembly to be quickly thrown away, thus achieving the purpose of emergency throwing.

[0007] Preferably, the locking assembly includes a fixing frame fixed to the main frame, and the locking frame is movably connected inside the fixing frame through a pin structure.

[0008] Preferably, the locking frame has a locking rod internally threadedly connected to it, and the fixing frame also has a locking block fixedly connected internally.

[0009] Preferably, one end of the locking rod is hook-shaped, and this hook-shaped end can be fastened to the first hook or the second hook, and the other end of the locking rod is provided with connecting threads.

[0010] Preferably, the locking frame is internally fixedly connected to a fixed shaft, and the fixed shaft has a threaded hole for installing the locking rod.

[0011] Preferably, one end of the locking rod is threaded into the inside of the threaded hole.

[0012] Preferably, the main frame has mounting holes for mounting hooks inside, and the first and second hooks are fixed with mounting shafts that are adapted to the mounting holes.

[0013] Beneficial effects:

[0014] Compared with existing technologies, this emergency throwing device with a double-ring hook for drones has the following advantages:

[0015] When an emergency throwing operation is required, the dual-axis motor drives the transmission rod to rotate, which in turn drives the small gear and the large gear to rotate, causing the threaded column to rotate in one direction and eventually detach from the fixed frame. After the fixed frame detaches, the locking assembly falls off, allowing the object suspended by the locking assembly to be quickly thrown away, thus achieving the purpose of emergency throwing.

A hanging rod 102, which is fixedly connected to the drone, is fixedly connected to the top of the main frame 101. A hanging groove 103 is provided at the bottom of the main frame 101, and a movable first hook 104 is installed in the hanging groove 103. A locking assembly 3 is provided on one side of the main frame 101. The locking assembly 3 includes a fixing bracket 301 mounted on the main frame 101. A threaded hole 3011 is provided on one side of the fixing bracket 301. The bottom of the main frame 101... A fixed frame 5 is fixedly installed in the unit. A dual-axis motor 4 is fixedly installed inside the fixed frame 5. The two output ends of the dual-axis motor 4 are fixedly connected to the transmission rod 6. The transmission rod 6 is connected to the pinion 7. One side of the pinion 7 is meshed with the large gear 8. One side of the large gear 8 is fixedly connected to the threaded post 9. The threaded post 9 is threadedly connected to the threaded hole 3011 of the fixed frame 301. When performing an emergency throw, the dual-axis motor 4 drives the transmission rod 6 to rotate, which in turn drives the pinion 7 and the large gear 8 to rotate, causing the threaded post 9 to rotate in one direction and eventually disengage from the fixed frame 301. After the fixed frame 301 is disengaged, the locking assembly 3 falls off, allowing the object suspended by the locking assembly 3 to be quickly thrown away, thus achieving the purpose of emergency throw.

[0027] Please refer to the following carefully. Figure 5 and Figure 6The inside of the fixed frame 301 is movably connected to the locking frame 302 via a pin structure. The inside of the locking frame 302 is threadedly connected to the locking rod 303. The inside of the fixed frame 301 is also fixedly connected to the locking block 304. The inside of the locking frame 302 is fixedly connected to the fixing shaft 3021. The inside of the fixing shaft 3021 is provided with a threaded hole 3022 for installing the locking rod 303.

[0028] Please refer to the following carefully. Figure 5 One end of the locking rod 303 is in the shape of a hook 3031, which can be fastened to the first hook 104 or the second hook 203. The other end of the locking rod 303 is provided with a connecting thread 3032, and one end of the connecting thread 3032 of the locking rod 303 is threaded into the inside of the threaded hole 3022.

[0029] Working principle: During emergency throwing, the dual-axis motor 4 drives the transmission rod 6 to rotate, which in turn drives the small gear 7 and the large gear 8 to rotate, causing the threaded column 9 to rotate in one direction and eventually disengage from the fixing frame 301. After the fixing frame 301 disengages, the locking assembly 3 falls off.
