Abstract

The invention relates to a multifunctional combined ladder including two vertical columns serving as clamp arms, and pedals which are arranged on the vertical columns at intervals, wherein the two vertical columns are rotatably connected to each other through a rotational shaft hole. The ladder also includes a plurality of pin structures, a plurality of U-shaped pins, two oriented wheels, a rotational structure, a support rod, two universal wheels, and another rotational structure. The vertical columns are connected to the pedals through the pin structures and the U-shaped pins for achieving support and rotation. The pedals can rotate on the vertical columns in parallel with the columns or at a certain angle to the vertical columns. Ladder feet are disposed on the bottoms of the vertical columns, wherein each oriented wheel is arranged at the outer side of one ladder foot while the two universal wheels are disposed respectively at the outer side of the other ladder foot and at a first pedal on the top of the vertical columns. The universal wheels and the oriented wheels are all connected to the vertical columns through the rotational structures. The ladder can be used as a herringbone ladder or a transportation ladder since the ladder can axially rotates around a shaft which is arranged in parallel with the rotational shaft hole. The ladder can be switched among the two functions easily and conveniently, so that the ladder saves labor intensity and has multiple functions.

Description

technical field [0001] The invention relates to a multifunctional combination ladder, which belongs to the technical field of household and construction tool devices. Background technique [0002] Ladders are used in many scenarios in daily life and work. With the development of industrialization, many traditional ladders remain in the state of one ladder and one use, with relatively large limitations, and can no longer meet the needs of current product diversification. Most ladders these days have the following problems. [0003] 1) One ladder and one use cannot meet the needs of diverse scenarios. [0004] 2) Some ladders are improperly selected, and the lifting is heavy, which reduces work efficiency. [0005] 3) The structure of the combined ladder is complex and difficult to operate. Contents of the invention [0006] The technical problem to be solved by the present invention is to design a ladder that combines the two functions of a transport ladder and a ladder...
