The invention belongs to the technical field of airplane boarding ladder design and manufacturing and provides a foldable composite material boarding ladder which comprises an upper ladder, a lower ladder, a supporting structure, a folder and a hook. The upper ladder and the lower ladder are connected through the folder, when the airstairs are in an unfolded state, the folder is self-locked to lock the upper ladder and the lower ladder, and the upper ladder and the lower ladder are folded by unlocking the folder; the supporting structure and the hook are both installed on the upper ladder supporting side, the hook is arranged on the upper ladder, and the installation position of the hook can be adjusted vertically and used for adjusting the distance between the hook and the supporting structure. The main body adopts a composite material hollow structure, the weight reduction is obvious, an integral forming process is adopted, the fiber performance of the composite material is fully exerted, the advantages of high strength, fatigue resistance and corrosion resistance are achieved, the stability is improved, and the service life is prolonged; the airstairs are high in degree of freedom of adjustment, high in applicability, stable in structure and comfortable to use; the foldable design is adopted, space is saved, and working intensity can be relieved.

    本发明提供了一种可折叠复合材料登机梯,属于飞机登机梯设计制造技术领域,包括上梯、下梯、支撑结构、折叠器、挂钩;上梯、下梯通过折叠器连接,登机梯处于展开状态时,折叠器自锁实现上梯与下梯锁定,解除折叠器锁定实现上梯与下梯折叠;支撑结构与挂钩均安装在上梯支撑侧,且挂钩在上,挂钩安装位置上下可调,用于调整其与支撑结构之间距离。本发明主体采用复合材料中空结构,减重明显,且采用一体成型工艺,充分发挥复合材料纤维性能,具有强度高、耐疲劳、抗腐蚀的优点,提高稳定性及使用寿命;登机梯调节自由度高,适用性强,结构稳定,使用舒适;采用可折叠设计,节省空间,可减轻工作强度。
