Abstract

The invention relates to a folding ladder for library management. The folding ladder comprises two symmetrically-arranged ladder bodies. Each ladder body comprises a movable seat (4), a first supporting rod (7) fixedly connected to the lower portion of the movable seat (4), a second supporting rod (15) slidably connected to the lower portion of the movable seat, and telescopic pedal rods (14) connecting the first supporting rod (7) with the second supporting rod (15). The movable seats (4) of the two ladder bodies are mutually connected rotationally. The interiors of the first supporting rods(7) are hollow, springs (8) and fixed pulleys (11) are sequentially arranged on the first supporting rods (7) from top to bottom, wherein one ends of the springs (8) are connected with the bottoms ends of the movable seats (4). A connecting rope (9) is further arranged between the two ladder bodies, wherein the two ends of the connecting rope (9) pass through the fixed pulleys (11) in the two ladder bodies correspondingly, and the connecting rope (9) is connected with the other ends of the two springs (8). Compared with the prior art, according to the folding ladder, using convenience is improved, the stability of the folding ladder is improved, and storage of the folding ladder is facilitated.
