Abstract

A related A type foldable mobile ladder comprises front wheels, revolute pairs, supporting rods, rear wheels, a chain, a handwheel and a supporting plate; the front wheels are symmetrically arranged at two sides of the bottom end of a first supporting rod; connection among the first supporting rod, a second supporting rod, a third supporting rod and a forth supporting rod are realized respectively via a first revolute pair, a second revolute pair, a third revolute pair and a forth revolute pair; one end of the handwheel is fixedly disposed on the supporting rods, and the handwheel is connected with the rear wheels via a two-stage transmission mechanism; and the supporting plate is arranged on the supporting rods. The foldable mobile ladder is simple in integral structure, high in practicability, convenient to manufacture and easy to popularize and use.

Description

technical field [0001] The invention relates to the field of life application technology, in particular to a folding activity ladder. Background technique [0002] Ladders are daily utensils. Even in the high-tech modern society, ladders still have an irreplaceable position. However, with the development of society and the progress of human society, people's pursuit is getting higher and higher. On the basis of practicality, convenience, multi-functionality and appearance are also extremely important. However, the ladders on the existing market all have common characteristics, that is, single performance, relatively large space occupation, and relatively heavy, which is extremely inconvenient, and it is difficult to meet the requirements of people in modern society for multifunctionality, convenience, and aesthetics. , and our design is to better meet the needs of customers, and improve on the basis of the original ladder to make it multi-functional, convenient and beautifu...
