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.

[0023] See also Figure 1-4 The utility model provides an embodiment: a pressure-resistant folding ladder for building decoration, comprising a placing platform 1, a folding ladder 2 is arranged on the lower surface of the placing platform 1, and can be folded. A foot pedal 3 is fixedly connected to the side surface of the folding ladder 2. When performing construction for building decoration, the staff needs to stand on the foot pedal 3 and climb up by stepping on the foot pedal 3. The bottom end of the folding ladder 2 is fixedly connected with an anti-sliding block 4, which can increase the friction of the whole device and avoid sliding on both sides.

[0024] The side surface of the folding ladder 2 is fixedly connected with a rotating shaft 5, and the rotating shaft 5 is respectively located on both sides of the folding ladder 2. The side surface of the rotating shaft 5 is rotatably connected with a rotating block 6, and the side surface of the rotating block 6 is fixedly connected with a supporting column 7. After the folding ladder 2 is opened, the supporting column 7 can provide support thereto, increase the overall pressure resistance of the ladder, and prevent the device from shaking. The side surface of the supporting column 7 is slidably connected to the folding ladder 2. When the folding ladder 2 is folded, the supporting column 7 can also be retracted into the side surface of the folding ladder 2. The outer surface of the supporting column 7 is provided with a positioning hole 8.

[0025] A connecting block 9 is fixedly connected to the lower surface of the placement table 1, and a supporting base 10 is fixedly connected to the lower surface of the connecting block 9. The size of the supporting base 10 is consistent with the distance between the two folding ladders 2 and will not affect the folding of the device. It can provide support for the entire device, increase pressure resistance, and avoid shaking and tipping of the ladder during building decoration construction.

[0026] The outer surface of the support base 10 is provided with mounting grooves 11, and there are four mounting grooves 11, which are convenient for clamping the four support columns 7. The outer surfaces of the support columns 7 are slidably connected to the mounting grooves 11, and the support columns 7 can be stuck in the mounting grooves 11 and cannot move, thereby providing support force for the folding ladders 2 on both sides to keep them stable.

[0027] The inside of the positioning hole 8 is slidably connected with a positioning column 12, and the positioning column 12 can limit the positioning hole 8 so that it is completely limited in the installation groove 11. The side surface of the positioning column 12 is fixedly connected with a sliding block 13, and the side of the sliding block 13 away from the positioning column 12 is fixedly connected with a sliding column 14. There are two sliding columns 14. Pulling the pulling block 15 can drive the two sliding columns 14 and the positioning column 12 to extend and retract at the same time. The side of the sliding column 14 away from the sliding block 13 is fixedly connected with the pulling block 15, which is convenient for pulling the positioning column 12 from the outside to quickly limit the support column 7. The side of the sliding block 13 away from the positioning column 12 is fixedly connected with a spring 16, and the spring 16 is sleeved on the outer surface of the sliding column 14. The sliding column 14 can increase the stability of the spring 16 when it is extended and retracted.

[0028] A movable groove 17 is provided on the upper surface of the placement table 1, and a two-way threaded rod 18 is rotatably connected inside the movable groove 17. The two-way threaded rod 18 extends to the outer surface of the placement table 1, and a rotating handle 19 is fixedly connected to the side surface of the two-way threaded rod 18, which is convenient for controlling the rotation of the two-way threaded rod 18 from the outside. A movable block 20 is threadedly connected to the side surface of the two-way threaded rod 18. The rotation of the two-way threaded rod 18 will drive the two movable blocks 20 to move in opposite directions at the same time, thereby limiting the tools during building decoration construction. The upper surface of the movable block 20 is fixedly connected to a limiting splint 21, and the lower surface of the limiting splint 21 is slidably connected to the placement table 1. The limiting splint 21 can limit the construction tools to prevent the tools from slipping and falling from the top.

[0029] When the embodiment of the present application is in use: after the folding ladder 2 is opened outward, the support column 7 is opened so that the support column 7 is stuck in the installation groove 11, the pulling block 15 is pulled outward to squeeze the spring 16, so that the sliding column 14, the sliding block 13, and the positioning column 12 move backward at the same time, and after the support column 7 is completely stuck in the installation groove 11, the pulling block 15 is released, and the reverse thrust of the spring 16 is used to reset the positioning column 12, the sliding block 13, and the sliding column 14, and the positioning column 12 is stuck in the positioning hole 8, which completely dislikes the support column 7, so that it supports the device as a whole, thereby increasing the pressure resistance of the device.
