Abstract

The invention provides a folding ladder with a locking device. The folding ladder with the locking device comprises two hinged ladder bodies and lateral supporting rod arranged on the two sides of the two ladder bodies. The folding ladder with the locking device further comprises a first connecting rod, a second connecting rod and the first locking device, wherein the first connecting rod is movably connected between the first ladder body and the first lateral supporting rod; the second connecting rod is movably connected between the second ladder body and the first lateral supporting rod; the first locking device is used for locking the first connecting rod and / or the second connecting rod and connected with the first connecting rod and / or the second connecting rod; and the first locking device is arranged on the first ladder body or the second ladder body or the first lateral supporting rod. The safety of the ladder is improved.

Description

Technical field [0001] The invention relates to a folding ladder, in particular to a folding ladder with a locking device. Background technique [0002] At present, folding ladders tend to fall sideways during use, causing injuries to persons on the ladders. Although there are folding ladders that can be laterally supported, that is, lateral support rods are set on both sides of the two ladders, but there is no effective restriction between the support rods and the ladders, and the support rods are easy to slide and still have a large Security risks. [0003] In summary, the prior art has the following problems: a folding ladder with lateral support rods is easy to slide on the support rods, which poses a greater safety hazard. Summary of the invention [0004] The invention provides a folding ladder with a locking device to solve the problem of a folding ladder with a lateral support rod. The support rod is easy to slide on the side and causes hidden safety hazards. [0005] To th...
