Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle hoisting equipment, in particular to a detachable hoisting connection device for unmanned aerial vehicles. Background Art

[0002] Drones are widely used in aerial photography, agriculture, surveying and mapping, news reporting, power inspection, disaster relief and other fields due to their convenience. When a drone needs to carry items, it is necessary to add a lifting device to its fuselage assembly to connect the carrying mechanism to carry items or related equipment. However, when lifting heavy objects, the heavy objects may shake in the corresponding placement mechanism due to their own size, which may cause the center of gravity of the drone lifting mechanism to shift, resulting in unstable take-off and landing, affecting work safety. To this end, we propose a detachable lifting connection device for drones. Utility Model Content
