Description
Technical Field
[0001] The utility model relates to the technical field of folding ladders, and particularly relates to a folding ladder convenient for transportation. Background Art
[0002] At present, the existing ladders can only be used as straight ladders or folding ladders, and there is no auxiliary support at the bottom of the ladders. When in use, the safety is poor and the overall functionality of the ladders is not strong. Secondly, and most importantly, the existing ladders are of an integral structure, and the ladder pedals and the ladder side bars on both sides are fixedly connected mechanisms and cannot be disassembled, resulting in a large volume during transportation, high transportation costs, and difficult transportation.
[0003] Patent Publication No. CN211144342U discloses a multi-purpose folding ladder convenient for transportation, which includes several groups of ladder unit bodies. The ladder unit bodies are connected to each other through folding joints to form a ladder body. Auxiliary support components can be detachably connected to the upper and lower ends of the ladder body. The ladder unit body includes side bars on both sides, and several cross bars are detachably connected between the two side bars as footrests.
[0004] In order to solve the problem that the existing ladders have a large volume during transportation, resulting in high transportation costs, the prior art is to connect several ladder unit bodies to each other through folding joints. During transportation, they can be folded and then packaged. Secondly, the cross bars and the side bars are detachably connected and can be disassembled and packaged during transportation, reducing the transportation volume. However, there will still be a situation where the volume of several ladder unit bodies increases after folding, and the cross bars and the side bars are lost during transportation, resulting in an increase in transportation volume and transportation costs.
