Foldable ladder applicable to various occasions

Abstract

The invention discloses a foldable ladder applicable to various occasions. The foldable ladder comprises a first climbing unit and a second climbing unit. The first climbing unit is hinged to the upper end of the second climbing unit. The outer sides of the two sides of the first climbing unit and the second climbing unit are connected through telescopic connecting parts respectively. The foldable ladder has a flat ground state, a step state, a stretching height-increasing state and a vehicle access board state. The foldable ladder applicable to various occasions has the advantages that the foldable ladder is folded during use under a normal situation; when the foldable ladder is used on a slope or steps, the telescopic four corners can timely adjust the support angle of the foldable ladder according to the gradient of the slope or steps, and the climbing safety of a user is guaranteed; the foldable ladder can be stretched and uses a wall face as the support to form a higher ladder so as to satisfy the requirement of high-position operations; the foldable ladder can also by unfolded to serve as an access board for vehicle loading and unloading.

Description

Technical field: [0001] The invention relates to the field of civil engineering machinery, in particular to a folding ladder applicable to various occasions. Background technique: [0002] Folding ladders are common civil engineering supplies and are an essential tool for workers to climb up and down. They can assist workers to climb up or down on the construction site. Folding ladders are opened when used and folded when used up for easy transfer. Due to its various advantages, it is widely used in various civil engineering and decoration projects. The convenience and dual-use of folding ladders are liked by more and more people. [0003] Although the folding ladder in the prior art has multiple advantages, it still needs to be improved in the following aspects: first, it has obvious disadvantages in climbing height, and it is difficult to meet higher height operations. Only the climbing tool can be replaced; secondly, the structure of the existing folding ladder is fixed,...

[0003] Although the folding ladder in the prior art has multiple advantages, it still needs to be improved in the following aspects: first, it has obvious disadvantages in climbing height, and it is difficult to meet higher height operations. Only the climbing tool can be replaced; secondly, the structure of the existing folding ladder is fixed, and the dimensions of the four corners of the folding ladder cannot be changed.
