The invention provides a folding ladder which comprises a first stand pillar, a second stand pillar, at least two pedal beams and positioning pins, wherein the first stand pillar and the second stand pillar are vertically arranged, and the cross sections of the first stand pillar and the second stand pillar are respectively in a C shape; the pedal beams are arranged in a polygonal line mode, each pedal beam comprises a first pedal and a second pedal which are mutually parallelly arranged at the two ends of the pedal beam, each first pedal is arranged at a lower position, each second pedal is arranged at a higher position, and an oblique connecting part is arranged between each first pedal and the corresponding second pedal by connecting; the end part of each first pedal is hinged with a stand pillar hinged hole of the first stand pillar by a pedal hinged hole; the end part of each second pedal is hinged with a stand pillar hinged hole of the second stand pillar by a pedal hinged hole; one positioning pin is arranged below each stand pillar hinged hole of the first stand pillar; and one positioning pin is arranged above each stand pillar hinged hole of the second stand pillar. The folding ladder disclosed by the invention can be folded for storage; and each pedal beam is designed in a two-pedal mode, thereby greatly saving raw materials.
Description
technical field [0001] The invention relates to the field of climbing ladders, in particular to a folding ladder. Background technique [0002] Ladders are widely used in all walks of life and can help operators climb from low places to high places. There is a kind of ladder that needs to be used leaning against the wall. It has a simple structure, but it cannot be folded by itself, so it requires a large storage space. And each step of the ladder all adopts a straight foot beam, and the steps of the higher ladder foot beam are more, so the overall consumables of the ladder are more, resulting in waste of cost and raw materials. [0003] It is not difficult to see that there are certain defects in the prior art. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a folding ladder, which can be folded for storage, and the pedal crossbeam adopts the design of double pedals, which greatly saves raw materials. [0005...
