Problems solved by technology

At present, there are many types of ladders. The common ladders are "herringbone" ladders or single-sided hanging ladders, and there are more complicated telescopic ladders and folding ladders. Their common feature is that they use slopes to climb. The fixed object forms a temporary support, which has poor stability and safety, and is not safe for one person to work; or it is large in size and takes up a lot of space, and it has poor flexibility and adaptability when working in some restricted spaces, and it is inconvenient to move and store

Abstract

The invention discloses a nail type vertical ladder which comprises a base, the upper surface of the base is detachably connected with a vertically-placed stand column, a lifting mechanism is fixed to the stand column, a moving part of the lifting mechanism ascends and descends in the vertical direction, and a pedal is fixed to the moving part of the lifting mechanism; the invention provides a nail-shaped vertical ladder which is characterized in that a base, a stand column and a movable pedal form a nail-shaped structure, the stand column stands on the base and forms the nail-shaped structure with the base, and the pedal is connected to the stand column and moves up and down along the stand column. When in use, the base and the pedal are mounted, and when in idle, the base and the pedal are folded, so that the device is good in stability, safe, reliable, capable of being operated by one person, small in size, light in weight and convenient to move and store.

Description

technical field [0001] The invention relates to the technical field of ladder manufacturing industry, in particular to a nail-shaped vertical ladder. Background technique [0002] Ladders are everyday utensils used for climbing. At present, there are many types of ladders. The common ladders are "herringbone" ladders or single-sided hanging ladders, and there are more complicated telescopic ladders and folding ladders. Their common feature is that they use slopes to climb. The fixed object forms a temporary support, which has poor stability and safety, and is unsafe for single-person operation; or it is large in size and takes up a lot of space, and it has poor flexibility and adaptability when working in some restricted spaces, and it is inconvenient to move and store. For this reason, it is necessary to design a new kind of ladder that is stable, easy to move and accommodate, and can be used in more restricted spaces with high flexibility.
