Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, in particular to a stable scaffolding device capable of preventing outward tilting. Background Art

[0002] The scope of use of scaffolding is very wide. Scaffolding no longer refers only to the various supports set up on construction sites in the construction industry for workers to operate and solve vertical and horizontal transportation;

[0003] For example, patent number CN218292692U discloses an anti-tilt scaffolding, including a top plate, both sides of the bottom of the top plate are fixedly connected to pull columns through a rotating shaft, the bottom of the pull column is provided with a bottom column, the bottom of the pull column extends to the inner cavity of the bottom column and is fixedly connected to a slider, the surface of the slider is slidably connected to the inner cavity of the bottom column, the bottom of the slider is fixedly connected to a spring, the bottom of the inner cavity of the bottom column is fixedly connected to a counterweight block, and the bottom of the spring is fixedly connected to the top of the counterweight block. The utility model comprises a top plate, a pulling column, a bottom column, a slider, a spring and a counterweight. When one side of the top plate is subjected to a large force and causes the top plate to lose balance and thus tilt, the tilted side of the top plate drives the pulling column at the bottom to move upward, thereby driving the slider to move in the inner cavity of the bottom column and thereby stretching the spring to deform the spring. The restoring elastic force of the spring pulls the slider and the pulling column, reducing the displacement distance of the pulling column and the slider in the inner cavity of the bottom column. At the same time, the counterweight increases the weight of the bottom column and cooperates with the spring to limit the bottom end of the spring, thereby preventing the spring from moving upward with the slider and the pulling column, thereby solving the problem of the present invention. The existing scaffolding can well assist workers in carrying out construction work at a higher height. However, since most scaffoldings lack a special anti-tilt device, when the workers are on the top of the scaffolding, if they step on the two ends of the scaffolding, it is easy to cause the scaffolding to tilt, which in turn leads to safety accidents and affects the work efficiency of the workers. However, when the anti-tilt scaffolding is used by the workers, the use area of ​​the scaffolding is limited, and only one person can be allowed to perform high-altitude work. When multiple people are required to work at the same time, the scaffolding is not convenient to adjust the use area, and its applicability is not high.

[0004] Therefore, in view of the problem that the use area of ​​the above-mentioned existing scaffolding is limited and can only allow one person to perform high-altitude work, and when multiple people are required to work at the same time, the scaffolding is not convenient to adjust the use area and has low applicability, a stable scaffolding device can be designed to prevent outward tilt. By rotating the knob, the bevel gear drives the screw to rotate during the rotation of the knob. Since the screw and the two extension platforms are engaged with each other, the two extension platforms extend outward during the rotation of the screw, which is convenient for expanding the workbench. The bottom ends of the workbench and the extension platform are respectively provided with a first support foot and a second support foot, and the workbench and the extension platform are supported by the first support foot and the second support foot. Utility Model Content
