Abrégé

A folding ladder comprising two ladder frames rotatably connected by two oppositely arranged frame hinge assemblies at the top, the ladder frames each including two parallel ladder legs, and several ladder frames; the frame hinge assembly is provided with a balancing member, one end of the balancing member is hinged with one frame hinge assembly, and the other end is connected with another frame hinge assembly in a locking manner; each step comprises hinged left and right step sections, the tops of the two ends of each step are is with snap-fit notches, so that the steps do not collide with the legs during the rotation process, the steps are in contact with the legs in both the unfolded and folded states, which makes the overall structure compact and has better shockproof effect, which is convenient for the transportation of the whole folding ladder.
