Double-purpose folding ladder

Abstract

The invention relates to a double-purpose folding ladder which comprises a fixed ladder, wherein a non-slip mat is arranged at the bottom of the fixed ladder; lugs are respectively arranged at two inner sides of the upper end of the fixed ladder, and a turnover ladder is arranged in the fixed ladder, close to the lower ends of the two lugs; a turnover seat board is arranged below the connecting part of the fixed ladder and the turnover ladder; two side surfaces of the seat board and two inner side surfaces of the turnover ladder are respectively arranged at intervals; a turnover connecting frame is arranged at the bottom of the other end of the seat board; turnover connecting rods are respectively arranged at the middle parts of two outer sides of the connecting frame; and the other ends of the two connecting rods are respectively connected with two inner hinges of the turnover ladder. The double-purpose folding ladder can be folded into a herringbone ladder and also can be folded into a straight ladder, the climbing height is increased, and the double-purpose folding ladder is simple in structure and convenient in use.

Description

technical field [0001] The invention relates to the field of ladders, in particular to a dual-purpose folding ladder. Background technique [0002] A foldable ladder is disclosed in the prior art 201320841974.3, which includes fixed rods, folding rods and telescopic rods; the fixed rods are connected by struts, and hinges are installed on the top ends; the folding rods are connected by step rods; : The top of the folding rod is installed on the fixed rod through a hinge, and can be folded around the hinge; the bottom of the folding rod is equipped with a retractable strut; the outer layer of the pedal rod is wrapped with a protective pad; The fixed rod only plays the role of auxiliary support, and the climbing height of the ladder is limited, so it is not suitable for high occasions. For this reason, we have developed a dual-purpose folding ladder, which can not only be folded into a ladder, but also folded into a ladder. The word ladder increases the climbing height, and h...
