Embodiment Construction

[0025] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] In order to reduce the space occupied by the cross-sectional size of the working ladder during transportation and storage, and to ensure the reliable fixation of the working ladder when it is folded, stored and unfolded for use, the present invention proposes a horizontal folding working ladder that can effectively reduce the cross-sectional size after folding. The folding structure and its positioning and fixing structure during folding and unfolding can reduce the cross-sectional area of ​​the working ladder during transportation and storage, and it can be easily and reliably fixed when the working ladder is folded and unfolded, and is suitable for the available length Where the space is long but the cross-sect...

Abstract

The invention relates to a vehicle-mounted folding working ladder, and belongs to the technical field of working ladders. According to the folding method and the corresponding fixing method of the vehicle-mounted working ladder, a fixing form of ladder sections and boundary beams of a traditional working ladder is changed into a rotating shaft moving form, folding in the direction of the boundary beams can be achieved, stable limiting is achieved during folding and unfolding, and effective fixing can be achieved. The working ladder is folded during transportation and storage and unfolded during working, and the space occupation of the cross section size during transportation and storage of the working ladder is further reduced.

Description

technical field [0001] The invention belongs to the technical field of working ladders, in particular to a vehicle-mounted folding working ladder. Background technique [0002] For special vehicles, they generally have their own working ladders for boarding, operation on both sides, etc. In order to save space, working ladders generally use the existing vehicle space, store them in a folded manner, and unfold them for use when needed. At present, the common folding method is longitudinal folding: that is, by folding in half or in multiple sections in the length direction, it actually reduces the length and size, similar to a herringbone working ladder. In this way, the cross-section of the ladder does not actually become smaller, resulting in the need for a larger space to store the folded working ladder. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to design a horizon...
