Abstract

A collapsible ladder is composed of two ladder frames, two movable joint groups, a handrail frame and an accommodating platform, wherein tops of the two ladder frames are mutually in pivot joint, and the two ladder frames are respectively provided with two longitudinal rod bodies and a plurality of separated horizontal rod bodies transversely connected between the two longitudinal rod bodies. The two movable joint groups are oppositely arranged on two sides of the two ladder frames, and two ends of each movable joint group are in pivot connection with opposite sides of the two ladder frames. The lower sections of two rod bodies on two sides of the handrail frame are in pivot connection with two sides of the upper section of one ladder frame and upwards extend to be located above the two ladder frames in spiral swinging mode. Two sides of the accommodating platform are in pivot connection with the handrail to swing spirally, extend and be located. The accommodating platform is folded and depended on the handrail, and the location of the handrail can be released, thereby achieving downward, spiral and swinging folding. The structure enables workers to be easy to stand on the ladder and climb up and down on the ladder, thereby improving using safety. The accommodating platform is utilized to conveniently place tools, devices and relative objects, thereby saving labor and working time and improving work efficiency. Furthermore, the handrail and the accommodating platform can be folded quickly, thereby avoiding occupying space.
