DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1~2 The utility model provides a modular scaffolding that is easy to disassemble and assemble, including four groups of support columns 1 and two pedals 8. The upper and lower parts of the four groups of support columns 1 are respectively fixedly installed with fixing sleeves 6. A cross bar 2 is welded between the fixing sleeves 6 at the same end of the two support columns 1. A fixing seat 7 is fixedly installed on one side of the fixing sleeve 6. One side of the fixing seat 7 is rotatably connected to a connecting rod 5, and the connecting rod 5 is connected at one end away from the fixing seat 7 through a hinge assembly. Two rotating rings 3 are rotatably provided on the two upper cross bars 2, and the pedals 8 are respectively fixedly connected to the rotating rings 3 on the two cross bars 2, and the two pedals 8 are connected through a clamping mechanism. When the two groups of pedals 8 are clamped together, the hinge assembly and the connecting rod 5 are in a fully opened and tight state.

[0026] The bottom of the support column 1 is fixed with a self-locking universal wheel 9 for easy movement. The support column 1 is preferably a retractable sleeve structure, which can adjust the height and is more convenient to use. A ladder 10 is welded between the cross bars 2 of the two support columns 1 on one side to facilitate getting on and off the scaffold. A rope 18 is also tied to one support column 1 to facilitate fixing and folding the scaffold after folding.

[0027] See also Figure 3~4 The hinge assembly includes a hinge block 4 and a connecting block 20. The inner cavities of the two hinge blocks 4 are respectively provided with fixed shafts 21. The connecting block 20 connects the fixed shafts 21 of the two hinge blocks 4 to realize the rotation connection of the two hinge blocks 4. The connecting rod 5 is fixedly connected to the hinge block 4, and the connecting block 20 realizes the foldability of the connecting rod 5.

[0028] A positioning plate 15 is also provided between the two articulated blocks 4 to limit the position of the two articulated blocks 4. After the two articulated blocks 4 are unfolded, the two articulated blocks 4 are connected by the positioning plate 15 to prevent the scaffold from being unstable due to deflection. Specifically, a positioning column 16 is fixed to the upper end of one articulated block 4, and a threaded hole 19 is provided at the upper end of the other articulated block 4. One end of the positioning plate 15 is rotatably connected to the positioning column 16, and the other end of the positioning plate 15 is connected to the threaded hole 19 through a screw 17.

[0029] See also Figure 5 The clamping mechanism includes a U-shaped fixing card 12 and a plug plate 14. The U-shaped fixing card 12 is fixed to the bottom of the pedal 8. The two ends of the plug plate 14 are respectively plugged into the U-shaped fixing card 12 at the bottom of the two pedals 8. A fixing bolt 13 is threadedly connected to at least one end of the plug plate 14. One end of the fixing bolt 13 presses the lower surface of the pedal 8. A handle 11 is also provided on the plug plate 14.

[0030] When in use, the scaffold is moved to the desired working position via the self-locking universal wheels 9, the rope 18 used to tie up the scaffold to prevent it from falling apart is untied, the support column 1 is grasped with both hands, and the support column 1 is pushed to both sides respectively, and the fixed seat 7 limits the movement trajectory of the connecting rod 5 to ensure that the connecting rod 5 moves horizontally with the fixed seat 7 as the center. In the process of pushing the support column 1 to both sides, the connecting rod 5 moves outward at the same time. When the connecting rods 5 on both sides are in the same plane, the hinge assembly opens 180 degrees, so that the scaffold is unfolded, and the fixed seat 7 cooperates with the connecting rod 5 and the hinge assembly to work. Personnel can expand or fold the scaffolding horizontally, thereby avoiding the need for disassembly and assembly of the scaffolding by the staff, reducing the workload and labor intensity of the staff, and facilitating the transportation and transfer of the scaffolding by the staff. At this time, screws 17 are used to connect the positioning plate 15 and the threaded hole 19 together through screws 17 and tighten the screws 17 to further fix the hinge block 4, thereby further improving the safety of the scaffolding and ensuring that the hinge block 4 will not be deformed when the staff is in use, causing the connecting rod 5 to return to the folded state and the scaffolding to be folded, thereby causing the staff to fall from the top of the scaffolding and endanger their lives.

[0031] Grab the handle 11 and insert one end of the plug plate 14 into the inner cavity of the inverted U-shaped fixing card 12 at the bottom of the pedal 8 on the other side, support the pedal 8 to ensure that the pedals 8 on both sides will not open suddenly when the staff performs construction work on it, and tighten the fixing bolt 13 at one end of the plug plate 14, so that one end of the fixing bolt 13 abuts against the surface of the pedal 8, fix the inverted U-shaped fixing card 12 between the fixing bolt 13 and the handle 11, and then fix the plug plate 14, to ensure that the vibration force generated by the staff above the pedal 8 will not affect the displacement of the plug plate 14 and then fall off, and prevent the pedal 8 from opening and causing the problem of people falling. Finally, lock the self-locking universal wheel 9 to fix the scaffold, and ensure that the self-locking universal wheel 9 will not slide during use. At this time, the scaffold is fully opened, and when the staff needs to enter the top of the scaffold to perform construction work, the staff can enter the top of the scaffold through the ladder 10 welded between the cross bars 2 on one side to perform construction work.

[0032] After the operation is completed, the scaffold is folded. When the folding is completed, the scaffold is bound with a rope 18 to prevent the scaffold from suddenly spreading out during the folding process. At this time, the self-locking universal wheel 9 is released to push the scaffold, so that the scaffold can be moved.
