Abstract

The invention discloses a multifunctional herring ladder. The multifunctional herring ladder comprises a front ladder body, a back ladder body and movable connection rods, wherein the tops of the front ladder body and the back ladder body are hinged together movably, the movable connection rods capable of opening at angles are fixed between the front ladder body and the back ladder body, and each of the front ladder body and the back ladder body consists of parallel hollow grab rods and transverse pedal rods arranged between the parallel grab rods at intervals. The lower end of the front ladder body sleeves telescopic ladder legs along the grad rod directions, and the telescopic ladder legs are fixed through positioning hole pins arranged on the left and right side faces of the telescopic ladder legs. Two pulleys are arranged at the lower end of the back ladder body and are mounted on the outer end faces of the lower ends of the grab rods coaxially. The multifunctional herring ladder is wide in use range and stable, simple and flexible in structure. By the aid of the pulleys mounted on the lower end face of the back ladder body, the multifunctional herring ladder is convenient to pull, so that carrying physical strength can be saved effectively.

Description

technical field [0001] The invention relates to a ladder, in particular to a multifunctional herringbone ladder. Background technique [0002] In daily life, a ladder is a kind of climbing tool used for decoration and the like in the space above the plane (such as the roof). Because when it is in use, the front and rear ladder rods and the ground form an isosceles triangle, which looks like a "person" character, so it is called "herringbone ladder" vividly. [0003] Existing herringbone ladder is divided into fixed herringbone ladder and movable herringbone ladder. The fixed ladder is a temporary building tool for people; the movable ladder is to connect the tops of the two ladders with loose leaves, and can be closed when moving. Because of its flexibility, it is widely used in electrician operations, especially During the construction and maintenance of circuits, construction workers often need to use ladders as climbing tools. [0004] In addition, in the prior art, a ...
