Description

Technical Field

[0001] The present application relates to the technical field of auxiliary construction tools, and in particular to a load-bearing folding ladder stool. Background Art

[0002] In various work scenarios involving high-altitude construction, construction workers usually need tools to assist in climbing. A load-bearing folding ladder stool is a typical tool for assisting in climbing. Structurally, the load-bearing folding ladder stool includes outriggers and pedals supported by the outriggers. The outriggers are stably supported on the ground, and construction workers step on the pedals to perform construction work.

[0003] The existing load-bearing folding ladder stool has a hinge installed in the middle position below the pedal and uses the hinge to fold and unfold the pedal. The hinge is fixed to the pedal with rivets. The pedal is a hollow aluminum alloy profile. When fixed with rivets, generally only the lower layer of the pedal is connected to the hinge. As a result, the load-bearing capacity of the load-bearing folding ladder stool is not strong and the safety factor is low. The hinge is welded to the pedal with an iron hinge. Since the strength of iron is higher than that of aluminum alloy, when people work on the load-bearing folding ladder stool, the iron can easily squeeze and deform the pedal, thereby causing danger. In addition, the pedal is also prone to arching at the hinge installation position, which is very unsafe. Utility Model Content

Figure 1-Figure 7 A load-bearing folding ladder stool comprises a leg 1 and a pedal 2 mounted on the leg 1, a hinge 3 is mounted at the middle position of the bottom surface of the pedal 2, the hinge 3 is made of high-strength galvanized steel metal material, the pedal 2 and the hinge 3 are fixed by a bolt 6, and the bolt 6 penetrates the pedal 2 and is fixedly connected with the hinge 3;

[0031] The pedal 2 includes a first pedal 21 and a second pedal 22, and the hinge 3 includes a first hinge 31 and a second hinge 32. The first hinge 31 and the second hinge 32 rotate around a rotating shaft 4, and the rotating shaft 4 is a high-strength bolt. The first hinge 31 is installed on the first pedal 21, and a first through hole 311 is opened on the first hinge 31. The first pedal 21 has a through hole matching therewith. After the bolt 6 passes through the through hole and the first through hole 311, the first hinge 31 is fixed to the first pedal 21. The second hinge 32 is installed on the second pedal 22, and a second through hole 321 is opened on the second hinge 32. The second pedal 22 has a through hole matching therewith. After the bolt 6 passes through the through hole and the second through hole 321, the second hinge 32 is fixed to the second pedal 22.

[0032] Holes are provided on the first hinge 31 and the second hinge 32. When the first pedal 21 and the second pedal 22 are unfolded and aligned in parallel, the hole is arranged on the side of the rotating shaft 4 away from the lower surface of the pedal 2 as viewed from the direction perpendicular to the upper surface of the pedal 2. A spring pin 5 is installed on the first hinge 31. The spring pin 5 is fixedly installed on the first hinge 31. The pin shaft 51 of the spring pin 5 passes through the hole to fix the relative position of the first hinge 31 and the second hinge 32, so that the first hinge 31 and the second hinge 32 no longer rotate relative to each other.
