The invention discloses an external hanging type ladder, a sleeping berth and a carriage. A mounting groove is formed in a frame main body, and a pedal assembly is mounted in the mounting groove to form a pedal level; and then, the pedal assembly is stably connected to the frame main body through the connection of a first connecting part and a second connecting part, so that the assembly of the external hanging type ladder is completed, the assembly difficulty is reduced, and the assembly efficiency of the external hanging type ladder is greatly improved. The pedal assembly and the frame bodyare of the two independent structures, and the first connecting part and the second connecting part are detachably connected, when the pedal part is broken or abraded, the pedal part on the pedal assembly can be independently maintained only by disconnecting the first connecting part and the second connecting part, and later maintenance work of the external hanging type ladder is facilitated. Thepedal assembly is located in the mounting groove, the pedal part is prevented from protruding out of the external hanging type ladder, the consistency of the structure of the external hanging type ladder on the overall appearance is guaranteed, and the appearance effect of the external hanging type ladder is greatly improved.

    本发明公开了一种外挂式梯子、卧铺及车厢,在框架主体上开设安装槽,并在安装槽内安装脚踏组件,以形成踩踏层级;接着,通过第一连接部与第二连接部相连,使得脚踏组件稳定连接在框架主体上,从而完成外挂式梯子的组装,如此,降低了装配难度,极大提高外挂式梯子的装配效率。由于脚踏组件与框架主体为两独立结构,且第一连接部与第二连接部可拆卸连接,因此,当踩踏部发生断裂或者磨损时,只需将第一连接部与第二连接部断开,即可对脚踏组件上的踩踏部进行独立维护,方便外挂式梯子的后期维护工作。同时,本实施例的脚踏组件位于安装槽内,避免踩踏部凸出外挂式梯子,使得外挂式梯子在整体外观上保证结构一致,大大提升了外挂式梯子的外观效果。
