Description

Technical Field

[0001] The utility model belongs to the field of machinery, and particularly relates to a ladder-cart dual-purpose device for indoor decoration. Background Art

[0002] Traditional indoor decoration work usually needs to use ladders and carts to complete. Ladders are used for high-altitude operations, such as installing lamps and painting walls; carts are used to carry decoration materials, tools, etc. However, this traditional method has some problems. First, ladders and carts respectively occupy space, which is not conducive to storage and handling; second, workers need to frequently switch between using ladders and carts during the use process, which not only has low efficiency but also increases the labor intensity.

[0003] In order to solve these problems, we designed a ladder-cart dual-purpose device for indoor decoration. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a ladder-cart dual-purpose device for indoor decoration, which not only improves work efficiency, reduces the labor intensity of workers, but also saves space and is convenient for storage and handling.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A ladder-cart dual-purpose device for indoor decoration, including a bottom frame, a first ladder frame, and a second ladder frame. A roller is rotatably installed on one side of the bottom frame, a top column is fixedly installed at the other end of the bottom frame, and mounting blocks are arranged inside the bottom frame, and the mounting blocks are installed at the four corners inside the bottom frame;

[0007] On both sides of one end of the first ladder frame, first connecting rods are installed. One side inside the bottom frame is rotatably connected to the first connecting rods on both sides of the first ladder frame through the mounting blocks. A connecting block is installed at the upper end of one side of the first ladder frame, and a seat board is rotatably installed at the upper end of one side of the first ladder frame through the connecting block. A first cross bar is fixedly installed inside the first ladder frame; the other end of the first ladder frame is lapped on the other side of the bottom frame;

[0008] On both sides of one end of the second ladder frame, second connecting rods are installed. The other side inside the bottom frame is rotatably connected to the second connecting rods on both sides of the second ladder frame through the mounting blocks. A first lapping cross bar is installed inside the second ladder frame. The other end of the second ladder frame is lapped on one side in the opposite direction of the bottom frame, and the second ladder frame and the first ladder frame are installed overlapping up and down.

[0009] As a further improvement of the utility model, the roller and the top column have the same height.

[0010] As a further improvement of the present utility model, a first limiting cross bar is installed at the bottom end of one side of the seat board, and the first limiting cross bar is fixedly installed inside the first ladder frame. A second limiting cross bar is installed at the bottom end of the other side of the seat board, and the second limiting cross bar is fixedly installed inside the first ladder frame.

[0011] As a further improvement of the present utility model, third limiting cross bars and fourth limiting cross bars are arranged on one side of the rotation part between the first ladder frame and the second ladder frame.

[0012] As a further improvement of the present utility model, a limiting block is arranged on the lower side of the seat board. The seat board is lapped on the first lapping cross bar on the second ladder frame and is limited by the limiting block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the present utility model, the first ladder frame and the second ladder frame are rotationally installed on the bottom frame, and through the limiting device, the functions of the ladder and the trolley are combined together, realizing the switching and sharing of the two functions. During use, workers can adjust the device into the ladder form for high-altitude operation according to needs, or adjust it into the trolley form for material handling. This not only improves work efficiency, reduces the labor intensity of workers, but also saves space, facilitating storage and handling. Description of the Drawings
