Abstract

The invention provides a domestic non-falling ladder, which comprises two pieces of ladders hinged through a hinge hinging shaft, wherein the first piece of ladder comprises a first vertical edge, a second vertical edge and a plurality of transverse edges connected between the first vertical edge and the second vertical edge; the domestic non-falling ladder also comprises a first lateral support rod and a second lateral support rod; the first lateral support rod is arranged at the first side of the two pieces of ladders; the second lateral support rod is arranged at the second side of the two pieces of ladders; the first lateral support rod and the second lateral support rod are respectively hinged onto the hinge hinging shaft through a hinging structure; the hinging structure comprises a support leg shaft sleeve rotatablely sleeving the hinge hinging shaft and a support leg connecting shaft radially penetrating through the support leg shaft sleeve; the axial line of the support leg connecting shaft is vertical to the axial line of the support leg shaft sleeve; the support leg is hinged onto the support leg shaft sleeve through a support leg connecting shaft; the support leg is hinged onto the hinge hinging shaft through the support leg shaft sleeve. The safety is improved.

Description

technical field [0001] The present invention relates to a kind of ladder, especially a kind of herringbone ladder, in particular to a household non-reversing ladder. Background technique [0002] Household ladders are mainly used on flat indoor working surfaces. At present, the commonly used household ladders are herringbone ladders. The herringbone ladder is composed of two ladders. The first ladder is provided with a horizontal ladder or pedals for people to climb, and the second ladder is a support bracket, which is not for people to climb, and plays the role of supporting the first ladder. The step ladder is easy to fold, but it is not stable enough, and it is easy to fall during work. [0003] To sum up, there are the following problems in the prior art: the ladder ladder is not stable enough, and it is easy to fall down during work. Contents of the invention [0004] The invention provides a ladder, such as a non-falling ladder for household use, to solve the probl...
