All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, an objective of the present embodiment is to solve the problem that the ladder is heavy and inconvenient to move, and provide a portable herringbone ladder with moving rollers, which includes two groups of symmetrical support bars 1, two vertical bars 2 connected between the two groups of support bars 1, and a cross bar 3 for connecting the two support bars 1 of each group, wherein a plurality of mutually parallel foot bars 4 are fixedly installed between the two support bars 1 of each group, a containing groove 9 is inwardly provided at the bottom end of the support bar 1, a moving device 11 is slidably installed in the containing groove 9, and the moving device 11 is used for a constructor to move the herringbone ladder. The cross bar 3 and the vertical bar 2 have supporting function on the two groups of the support bars 1, and the foot bars 4 can be used for construction work of constructors.

In order to facilitate the use of the portable herringbone ladder with the movable rollers, the movable device 11 comprises a movable block 12, and the rollers 7 are fixedly arranged at the bottom of the movable block 12 and used for being quickly taken out by constructors when the herringbone ladder is moved. The roller 7 can conveniently move the portable double ladder, so that the manpower deficiency caused by overlarge double ladder quality is avoided.

In order to safely use the portable double ladder with the movable rollers, the side wall of the handrail 1 is provided with a limiting bolt 5, a bolt through hole 6 matched with the limiting bolt 5 is formed in the side wall of the handrail 1 close to the bottom edge, the limiting bolt 5 is slidably inserted into the bolt through hole 6, one end of the limiting bolt 5 is provided with a handle 8, the limiting bolt 5 is rotatably inserted into the bolt through hole 6 matched with the limiting bolt through the handle 8 to fix the rollers, and the rollers cannot fall when the double ladder is moved.
