Adjustable suspension ladder

Abstract

The invention discloses an adjustable suspension ladder. The adjustable suspension ladder comprises a ladder frame, an upper hanging plate arranged at the upper end of the ladder frame, a downward pressing plate arranged at the lower end of the upper hanging plate, and a supporting plate hinged to the end of the downward pressing plate, wherein a main body of the ladder frame is of a Z-shaped frame structure, and a clamping groove of a U-shaped groove body structure is formed in the upper end of the ladder frame. The lower end of the whole ladder has the good supporting effect through the Z-shaped structure of the ladder frame; the upper hanging plate in clamped fit with the upper end of the ladder frame can be horizontally assembled with the upper end of the ladder frame and can also be vertically assembled with the upper end of the ladder frame, the supporting face of the upper end of the ladder frame can be enlarged through the former, and the fixing effect of a barb can be achievedon the inner side of the wall surface through the latter when a height ascending point is located on the vertical wall surface; and a reel II is rotated to drive a reel I to rotate together, thus steel wire ropes on the two sides of the ladder frame are wound tightly, the supporting plate and the downward pressing plate are lifted up through the steel wire rope, thus a clamping mechanism is formed by the downward pressing plate and the upper end face of the ladder frame, and the safe stability of the whole ladder is improved.

Description

technical field [0001] The invention relates to the technical field of hardware, in particular to an adjustable hanging ladder. Background technique [0002] A ladder is a common hardware tool for climbing and climbing. It can be divided into single-sided ladders, herringbone ladders, telescopic ladders and dual-purpose ladders in terms of structure. Ladders are an ideal auxiliary tool when climbing. In actual use, the following disadvantages still exist: [0003] 1. When the contour point is a protruding suspended surface, the ladders in the prior art generally cannot be firmly anchored, so that the ladder cannot reach the contour point quickly and effectively; [0004] 2. The upper end of the ladder in the prior art lacks fixing devices with the upper and lower ends of the suspended surface, which causes the ladder to easily slip off from the supporting point, resulting in a safety accident. Contents of the invention [0005] The object of the present invention is to p...
