Multi-functional household ladder

Abstract

The invention discloses a multi-functional household ladder. The multi-functional household ladder comprises a climbing part, a supporting part, hinges, safe tension bars and a rotation part. The climbing part comprises a first front upright column, a second front upright column, a fixed step and a telescoping hand rail, wherein the two ends of the fixed step are connected with the lower portion of the first front upright column and the lower portion of the second front upright column through screws, the two lower ends of the telescoping hand rail are arranged in the top of the first front upright column and the top of the second front upright column, and the supporting part is connected with the first front upright column and the second front upright column through the hinges and the safetension bars. The rotation part comprises a top step, a transformation step, transformation tension bars and supporting rods, the top step is movably connected with the transformation tension bars through the transformation tension bars and the supporting rods, the transformation tension bars are movably connected with the supporting rods through bolts, and the lower ends of the supporting rods are movably connected with the inner sides on the upper portions of rear upright columns through bolts. The structural design is fashionable, high-end, textured, simple in operation, safe, firm and lowin space occupation.

Description

technical field [0001] The invention relates to a ladder, in particular to a multifunctional household ladder. Background technique [0002] In daily life, it is necessary to use a ladder when taking taller items or changing light bulbs, etc. The current household ladders mainly have various deficiencies, and most of them are made by riveting technology. During use, because the tensile force of the connecting parts cannot reach the fixed stability, it is easy to loosen, which will cause the whole ladder to shake, and the ladder will lose its balance. Blind rivet holes and material heads in non-standard joints are prone to burrs, which will scratch or pinch operators; secondly, household ladders with fixed step widths below 80mm are all unilaterally open grooves Mainly, it is easy to step on, twist and deform during use, and there are potential safety hazards.

Problems solved by technology

[0002] In daily life, it is necessary to use a ladder when taking taller items or changing light bulbs, etc. The current household ladders mainly have various deficiencies, and most of them are made by riveting technology. During use, because the tensile force of the connecting parts cannot reach the fixed stability, it is easy to loosen, which will cause the whole ladder to shake, and the ladder will lose its balance. Blind rivet holes and material heads in non-standard joints are prone to burrs, which will scratch or pinch operators; secondly, household ladders with fixed step widths below 80mm are all unilaterally open grooves Mainly, it is easy to step on, twist and deform during use, and there are potential safety hazards. Although the current wide-type step adopts a movable vacated connecting bar to connect and fix it, it is easy to cause shaking during use, which is not stable enough, and the continuous folding time After a long time, the connection parts will be easy to loosen and fall off, which is not safe; again, it cannot be shrunk to a smaller size for storage, and it takes up a lot of space. It cannot be used for other purposes except for climbing and climbing. It has a single function

In addition, the current household ladders are mainly made of wood or steel, but wooden and steel ladders are very heavy and difficult to carry, and the environment is limited during storage, so they need to be stored in a dry and ventilated place, especially wooden ladders are affected by damp and mildew After changing, it will be deformed and aged, causing the nails and slotted parts to fall off. After the steel ladder is damp, the skin will fall off and rust, and it will break and collapse during use, which will affect safety.
