Herringbone ladder convenient to move

Abstract

The invention relates to the technical field of carton packaging, and discloses a herringbone ladder convenient to move. The herringbone ladder comprises a connecting rod, two groups of hinges, four groups of support rods and a plurality of groups of pedals, the two groups of hinges are respectively arranged on the left side and the right side of the connecting rod, the bottom side walls of the two groups of hinges are respectively and movably provided with two groups of support rods, and a connecting device, an extending device, a limiting device, a fixing device and a clamping device are arranged outside the connecting rod. According to the herringbone ladder convenient to move, the gravity center of a worker deviates to one side of the herringbone ladder, the worker can deflect the side, away from the gravity center, of the herringbone ladder with legs, the two groups of connecting movable grooves are each in a rounded rectangle shape, so that when the herringbone ladder deflects, the connecting movable grooves cannot block rotation of the connecting rod, therefore, the worker can conveniently change the angle of the herringbone ladder, and the effect of convenient movement is achieved.

Description

technical field [0001] The invention relates to the technical field of carton packaging, in particular to a convenient mobile ladder. Background technique [0002] Herringbone ladder: A kind of climbing tool used for decoration in the space above the plane (such as the roof), because when used, 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] At present, the existing decoration workers on the market need to use the ladder when decorating the walls. In order to save time, the decoration workers need to learn to move the position of the ladder on the ladder. The ladders are fixed together, so the joints of the ladders need to be loosened to a certain extent, so that the angle of the ladders can be rotated a little more conveniently, but there are safety hazards and it is thankless. For this reason, we propose a kind of herringbone ladder that is convenient ...
