[0034] Working principle:

[0035] When the scaffold is installed, first, the two frame mechanisms are erected, then the first U-shaped hooks 8 at both ends of the two unfolded folding rod mechanisms are hung on the horizontal pipes 1 at the bottom of the two frame mechanisms respectively, then the two first U-shaped hooks 8 on the same horizontal pipe 1 are slid to the sleeves 4 at both ends of the horizontal pipe 1, at this time, the sleeves 4 and the connecting pipes 2 are fixed to each other under the locking of the locking assembly, so that the docking sliding strips 5 on the three sides of the outside of the sleeves 4 are aligned with the three sliding grooves on the first U-shaped hooks 8, in the process of completely sliding the docking sliding strips 5 into the sliding grooves on the first U-shaped hooks 8, the two L-shaped clamping plates 20 are pressed towards the inclined surfaces on both sides of the pointed head sliding block 19 under the extrusion of the first U-shaped hooks 8, so that the pointed head sliding block 19 moves downward, the rectangular sliding block 15 is pushed to slide downward by the pointed head sliding block 19, and the rectangular clamping block 18 is driven to move downward by the rectangular sliding block 15, when the two L-shaped clamping plates 20 are pressed and combined, the rectangular clamping block 18 has completely separated from the locking groove 13, so that the sleeve 4 rotates relative to the connecting pipe 2; after the two folding rod mechanisms are installed, the folding platform mechanism is installed between the two horizontal pipes 1 at the construction height in the two frames, and the second U-shaped hook 11 on the unfolded folding platform mechanism is hung on the horizontal pipe 1, and then the second U-shaped hook 11 is slid to be docked with the sleeve 4 and the docking sliding strip 5, so that the installation of the scaffold is completed.

[0036] When the scaffold encounters a narrow passage, the middle part of the folding rod mechanism and the folding platform mechanism can be bent upward, at the time of bending, the sleeve 4 docked by the first U-shaped hook 8 or the second U-shaped hook 11 is no longer locked by the locking assembly and can rotate freely, and will rotate correspondingly with the bending of the folding rod mechanism and the folding platform mechanism, so that the two frame mechanisms on both sides are combined, so that the folding of the whole scaffold is completed, so that the scaffold passes through the narrow passage; when the construction is completed, the folding rod mechanism and the folding platform mechanism are directly straightened to realize the unfolding of the scaffold, and the unfolded scaffold is directly used for construction.

[0037] The scaffold is fixed by sliding the sliding groove on the first U-shaped hook 8 and the second U-shaped hook 11 on the butt joint sliding bar 5 outside the sleeve pipe 4, so that the sliding groove on the first U-shaped hook 8 and the second U-shaped hook 11 does not touch the locking assembly, thereby fixing the connecting pipe 2 and the sleeve pipe 4 by the locking assembly, and fixing the folding pull rod mechanism and the folding platform mechanism relative to the two side piece connecting mechanisms, so that the scaffold can be used as a stable construction platform; when the scaffold is fixed on the stairs, the two piece frame mechanisms are placed on the low steps and the high steps, respectively, the highest horizontal pipe 1 and the second lowest horizontal pipe 1 of the piece frame mechanism on the low steps are at the same height as the second highest horizontal pipe 1 and the lowest horizontal pipe 1 of the piece frame mechanism on the high steps, respectively, and then the folding pull rod mechanism is set up and fixed between the highest horizontal pipe 1 of the piece frame mechanism on the low steps and the second highest horizontal pipe 1 of the piece frame mechanism on the high steps, and the folding pull rod mechanism is set up and fixed between the second lowest horizontal pipe 1 of the piece frame mechanism on the low steps and the lowest horizontal pipe 1 of the piece frame mechanism on the high steps, so that the scaffold can be stably installed on the stairs as a construction platform.

[0038] In summary, the scaffold has a simple overall structure, can be quickly assembled on site to ensure construction progress, and can be quickly disassembled after use, thereby greatly reducing the occupied space and facilitating storage and transportation by truck; when encountering a narrow passage, the folding pull rod mechanism and the folding platform mechanism can be bent upwards from the middle, so that the overall frame body is folded, and after passing through the narrow passage, the scaffold can be completely unfolded by straightening the folding pull rod mechanism and the folding platform mechanism, so that the scaffold can be used for high-altitude construction, thereby avoiding the need to disassemble and reassemble when encountering a narrow passage that cannot be passed through, thereby greatly improving construction efficiency; the scaffold can be stably installed on the stairs and can provide a stable construction platform for construction needs, making the scaffold versatile and greatly improving the practicality and applicability of the scaffold.
