[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0022] like Figure 1-Figure 4 As shown, the present embodiment provides a decoration ladder with a folding structure for indoor decoration, comprising a fixing rod 2, wherein the fixing rod 2 has two groups, a first cross bar 3 is arranged in an array between the fixing rods 2, an adjusting cavity 8 is opened on the back wall of the fixing rod 2, a screw rod 9 is installed in the adjusting cavity 8, a screw block 10 is sleeved on the screw rod 9, a lifting frame 5 is fixed on one side wall of the screw block 10, a second cross bar 4 is arranged in an array between the inner walls of the lifting frame 5, a sub gear 13 is fixed to the bottom end of the screw 9, a main gear 12 is connected to one side of the sub gear 13, a rotating shaft 11 is sleeved in the main gear 12, a knob 6 is fixed at one end of the rotating shaft 11, and a positioning bolt 7 is arranged on the knob 6.

[0023] The first cross bar 3 is welded between the fixed bars 2 , an anti-slip pad is arranged on the first cross bar 3 , an adjustment cavity 8 is formed on the fixed bars 2 , the fixed bars 2 and the first cross bar 3 can be combined to form a fixed ladder, and the adjustment cavity 8 provides an installation position for the screw rod 9 .

[0024] The screw rod 9 is rotationally connected to the adjusting chamber 8, the screw block 10 is threadedly connected to the screw rod 9, and the screw block 10 is slidingly connected to the adjusting chamber 8. During the rotation of the screw rod 9, the screw block 10 can move under the action of the thread.

[0025] The lifting frame 5 is welded on the screw block 10, and the second cross bar 4 is welded inside the lifting frame 5. The lifting frame 5 is a U-shaped structure. The lifting frame 5 and the second cross bar 4 form a lifting ladder. The screw block 10 can drive the lifting frame 5 to move, thereby adjusting the telescopic length of the decoration ladder.

[0026] The sub-gear 13 is fixed at the bottom end of the screw 9, the main gear 12 is meshed with the sub-gear 13, both the sub-gear 13 and the main gear 12 are helical gears, the rotating shaft 11 is fixed inside the main gear 12, the rotating shaft 11 drives the sub-gear 13 to rotate through the main gear 12, and the sub-gear 13 drives the screw 9 to rotate.

[0027] The knob 6 is fixed at one end of the rotating shaft 11, and the positioning bolt 7 is connected to the knob 6 by a thread. A positioning hole is opened on the side wall of the fixing rod 2 at a position corresponding to the positioning bolt 7.
