[0002] Architectural decoration can make buildings satisfy people's visual and tactile enjoyment, and further improve the spatial quality of buildings. Therefore, architectural decoration has become an indispensable part of modern construction projects. When working, workers often use tools such as ladders to work at high places. At present, the ladders on the market are mainly composed of a top plate, a frame, a crossbar and a universal wheel. Among them, the universal wheel makes the ladder more convenient to move. At the same time, the staff can temporarily place the tools to be used on the top plate, which makes it more convenient to take the tools. For example, a decorative ladder for architectural decoration disclosed in Chinese patent announcement number CN212105050U, but because the storage area on the ladder is fixed, it cannot be adjusted according to the number or amount of tools used, and then the insufficient storage area on the ladder often causes the tools to be unable to be placed on the ladder, which makes the ladder inconvenient to use.

[0025] Reference Figure 1-7A novel ladder comprises a top plate 1, a first U-shaped plate 2 is fixedly connected to the upper surface of the top plate 1, an expansion plate 3 is fitted on the inner wall of the first U-shaped plate 2, a rectangular frame 4 is fixedly connected to the bottom of the expansion plate 3, the inner wall of the first U-shaped plate 2 and the upper surface of the top plate 1 are in contact with the surface of the rectangular frame 4, sliding holes 5 are provided on the front and rear sides of the rectangular frame 4, a sliding column 6 is fitted on the inner wall of the sliding hole 5, and the moving trajectory of the sliding column 6 is guided by the sliding hole 5, a handle 7 is fixedly connected to the front and rear sides of the sliding column 6, a spring 8 is fixedly connected to the surface of the handle 7 and the front and rear sides of the rectangular frame 4, a support column 9 is fixedly connected to the surface of the sliding column 6, the bottom of the expansion plate 3, the upper surface of the top plate 1 and the inner wall of the rectangular frame 4 are in contact with the surface of the support column 9, the inner part of the top plate 1 A strip hole 10 is opened, and the inner wall of the strip hole 10 is fixedly connected with a second U-shaped plate 11, and a card block 12 is fitted on the inner wall of the second U-shaped plate 11, and the upper surface of the card block 12 is fixedly connected to the bottom of the support column 9. The elastic force of the spring 8 is greater than the sum of the gravity of the sliding column 6, the handle 7, the support column 9 and the card block 12. When the card block 12 is inserted into the second U-shaped plate 11, the elastic force of the spring 8 makes the card block 12 and the second U-shaped plate 11 inseparable, and the expansion plate 3 is fixed in the first U-shaped plate 2 through the cooperation of the card block 12 and the second U-shaped plate 11. When the card block 12 is separated from the second U-shaped plate 11, the expansion plate 3 can be directly pulled out from the first U-shaped plate 2, and the storage area on the ladder can be increased through the expansion plate 3. The bottom of the top plate 1 is fixedly connected with a ladder frame 13.

[0026] The ladder frame 13 includes a cross bar 131, and the left and right sides of the cross bar 131 and the bottom of the top plate 1 are fixedly connected with a frame body 132, the bottom of the cross bar 131 and the side of the frame body 132 are fixedly connected with a reinforcement block 21, the bottom of the frame body 132 is fixedly connected with a mounting plate 133, and the bottom of the mounting plate 133 is fixedly connected with a locking universal wheel 134. The locking universal wheel 134 makes it easier to move the ladder, and when the ladder moves to a specified position, the locking universal wheel 134 is locked to prevent the ladder from moving easily.

[0027] Embodiment 2:

[0028] Reference Figure 1-3The side of the rectangular frame 4 is fixedly connected with a hollow block 14, the inner wall of the hollow block 14 is fixedly connected with a slide cylinder 15, the inner wall of the slide cylinder 15 is fitted with a connecting rope 16, the connecting rope 16 can be guided by the slide cylinder 15, the top of the connecting rope 16 is fixedly connected with a limit block 17, the bottom of the connecting rope 16 is fixedly connected with a connecting block 18, the limit block 17 and the connecting block 18 cooperate to make the connecting rope 16 and the slide cylinder 15 inseparable, the bottom of the connecting block 18 is fixed A hook 19 is connected. When the user stands on the ladder frame 13, the user pulls the connecting rope 16 to pull the items hung on the hook 19 to the top plate 1, so that the user does not need to get down from the ladder frame 13 when taking the items. A magnetic block 20 is fixedly connected to the side of the connecting block 18. When the hook 19 is not in use, the hook 19 can be fixed to the frame 132 through the suction force of the magnetic block 20 on the frame 132, so that the hook 19 will not swing freely when the ladder is moved.

[0029] When the user stands at the designated height, the user can pull the connecting rope 16 to pull the item hung on the hook 19 to the top plate 1, and then place the item on the first U-shaped plate 2. At this time, the item is supported by the first U-shaped plate 2. When the storage area of ​​the ladder needs to be increased, the handle 7 is first pulled to separate the block 12 from the second U-shaped plate 11. Then, the expansion plate 3 is pulled out from the first U-shaped plate 2 to increase the storage area of ​​the ladder. When the storage area of ​​the ladder needs to be reduced, the expansion plate 3 is pushed into the first U-shaped plate 2, and the block 12 is inserted into the second U-shaped plate 11. At this time, the elastic force of the spring 8 makes it impossible to separate the block 12 from the second U-shaped plate 11, and the expansion plate 3 is fixed in the first U-shaped plate 2 through the cooperation of the block 12 and the second U-shaped plate 11.
