Description

Mechanism for lifting first-aid kit and unmanned aerial vehicle with mechanism Technical Field The utility model relates to the technical field of unmanned aerial vehicle lifting, in particular to a mechanism for lifting a first-aid kit and an unmanned aerial vehicle with the mechanism. Background With the rapid development of unmanned aerial vehicle technology, the unmanned aerial vehicle is increasingly widely applied to the field of emergency rescue. In complex environments such as natural disasters, accident sites or remote areas, even battlefield first aid, unmanned aerial vehicles gradually become an important tool for emergency medical material transportation by virtue of the advantages of quick response, flexibility, no limitation of terrain and the like. Especially, aiming at the quick delivery requirement of the first-aid kit, the unmanned aerial vehicle can break through the limitation of the traditional ground transportation and provide key support for life rescue in the 'golden rescue time'. Unmanned aerial vehicle handling among the prior art mainly comprises unmanned aerial vehicle, hoisting accessory, couple etc. and hoisting accessory's lifting rope only has one generally (based on the problem of lifting roller rolling), then in practice single lifting rope easily appears breaking (or unexpected scratch off) and lead to unable appointed region of sending first aid article hanging, this belongs to fatal problem in complex environment such as battlefield first aid, for this reason the skilled person, has proposed a mechanism of handling first aid kit and unmanned aerial vehicle that has this mechanism. Disclosure of Invention The utility model aims to solve the problem that a single lifting rope is easy to break when an emergency article is lifted by an unmanned aerial vehicle, so that the emergency article cannot be lifted to a designated region.
