The invention provides a universal catapult rack for small and medium-sized unmanned aerial vehicles. The universal catapult rack comprises a catapult rack body, a catapult trolley, a catapult mechanism, a buffer mechanism and an unlocking safety device. The ejection frame body comprises a sliding rod, a front supporting leg and a rear supporting leg, the sliding rod is provided with an energy storage end and a launching end, the front supporting leg is connected with the launching end, and the rear supporting leg is connected with the energy storage end so as to support the sliding rod to be erected to a launching state. The ejection mechanism comprises a plurality of elastic ropes and at least one pair of fixed pulley assemblies, the fixed pulley assemblies are symmetrically arranged on the two sides of the launching end, the elastic ropes are arranged on the two sides of the sliding rod, one ends of the elastic ropes are connected with the ejection trolley, and the other ends of the elastic ropes bypass the fixed pulley assemblies to be connected with the rear supporting legs to provide ejection force for the unmanned aerial vehicle. According to the technical scheme, the technical problems that in the prior art, an elastic rope is large in one-time installation and fixing operation difficulty, and the elastic rope is difficult to replace, so that an ejection frame does not have universality are solved.

    本发明提供了一种用于中小型无人机的通用型弹射架,通用型弹射架包括:弹射架本体、弹射小车、弹射机构、缓冲机构和解锁保险装置。弹射架本体包括滑杆、前支腿和后支腿,滑杆具有储能端和发射端,前支腿与发射端相连,后支腿与储能端相连,以支撑滑杆起竖到发射状态。弹射机构包括多条弹力绳和至少一对定滑轮组件,一对定滑轮组件对称地设置在发射端的两侧,多条弹力绳设置在滑杆的两侧,一端与弹射小车相连,另一端绕过定滑轮组件与后支腿相连,为无人机提供弹射力。应用本发明的技术方案,以解决现有技术中弹力绳一次性安装固定操作难度大,弹力绳较难更换导致弹射架不具备通用性的技术问题。
