This utility model belongs to the field of airborne equipment, specifically a
centimeter-level positioning mechanism for an airborne camera device used in unmanned aerial vehicles (UAVs). It includes a main body with a disassembly /
assembly mechanism at its bottom, comprising a disassembly /
assembly component and a camera component. The disassembly /
assembly component includes a fixed plate with a connecting plate fixedly mounted on its top. A driving
bevel gear is rotatably mounted on one side of the connecting plate, and a rotating
handle is fixedly mounted on one end of the driving
bevel gear. A
bevel gear plate meshes with the top of the driving bevel gear, and two driven bevel gears mesh with the bottom of the bevel gear plate. The two driven bevel gears are rotatably mounted on the top of the connecting plate, and a threaded ring is formed on the top of the bevel gear plate. By rotating the rotating
handle, the driving bevel gear is driven, which, through the bevel gear plate and rack, drives a
metal clip to engage the connecting plate. Combined with the magnetic force of a magnetic ring, this achieves tool-free, rapid disassembly / assembly of the camera device, solving the problem of cumbersome traditional bolt installation and improving equipment replacement efficiency.
