Abstract

The invention provides an all-terrain non-falling ladder. The all-terrain non-falling ladder comprises two ladder units, wherein the two ladder units are a first ladder unit and a second ladder unit which are hinged to each other through first hinge shafts respectively; the first ladder unit comprises a first vertical side and a second vertical side; the first vertical side comprises a first main ladder column hinged to the first hinge shaft, a first telescopic ladder column arranged below the first main ladder column and capable of sliding relative to the first main ladder column, and a first locking device; the first main ladder column is connected with the first telescopic ladder column through the first locking device in a clamping manner; the first locking device comprises a convex first positioning part; a first rack or a plurality of first grids in stripped arrangement which are connected with the first positioning part in a clamping manner are arranged on the first main ladder column or the first telescopic ladder column. In an uneven workplace, the all-terrain non-falling ladder can be stably supported on an uneven working surface through stretch and retraction, so that the safety coefficient is increased.

Description

technical field [0001] The invention relates to a ladder suitable for use in various terrains, especially suitable for use in various uneven terrains, that is, an all-terrain non-reversing ladder. Background technique [0002] At present, existing ladders are generally used on planes, but for some workplaces, the ground is uneven, and the fulcrums of the ladder are not located on the same plane, and some fulcrums are suspended, and there will be safety problems when working on the ladder. [0003] To sum up, the following problems exist in the prior art: when the ground is uneven, some fulcrums of the ladder become suspended, making it unsafe to work on the ladder. Contents of the invention [0004] The invention provides a ladder, especially an all-terrain non-inverting ladder, to solve the problem that some fulcrums of the ladder become suspended in the air and it is unsafe to work on the ladder when the ground is uneven. [0005] For this reason, the present invention ...
