The plate body 111, the rear plate 12, the bottom plate 13, and the two side plates 16 together enclose a first receiving cavity 17 for storing painting tools. The design of the transverse partition 15 divides the first receiving cavity 17 into a first cavity 171 and a second cavity 172 arranged vertically, significantly increasing the storage space. This layered design not only improves the overall utilization rate of the first receiving cavity 17, but also allows painting tools of different types or sizes to be stored in a more organized manner. Painting tools can be stored by category or... The tools are placed in different cavities for their respective purposes, reducing the time spent searching for specific tools and improving work efficiency. This design also helps protect the drawing tools from impacts or damage. The top of the first cavity 171 has a first opening, facilitating the insertion and removal of drawing tools.

Whether creating indoors or sketching outdoors, this design provides good support, ensuring that the multi-functional painting cart 100 can work stably and reliably in various environments.

[0040] The technical solution of this utility model uses a transverse partition 15 to divide the first receiving cavity 17 into a first cavity 171 and a second cavity 172 arranged vertically, which realizes the effective utilization and classified storage of the first receiving cavity 17, significantly improving the storage efficiency and ease of use of painting tools. By using a cover plate 14 and a retrieval window 112, it not only ensures the convenience of storing and retrieving painting tools from the first cavity 171 or the second cavity 172, but also ensures that the painting tools will not fall or be affected by the external environment during transportation, thus providing better protection, reducing the risk of damage or loss, and further enhancing the functionality and practicality of the equipment. By using a pull rod assembly 2 and a roller assembly 3, the multi-functional painting cart 100 can easily move on various terrains, greatly improving the convenience and efficiency when carrying a large number of painting tools.

[0041] Please see Figure 1 In one embodiment, the retrieval window 112 includes a window body 1121 and a fastener 1122. The window body 1121 is rotatably mounted on the plate body 111 so that the window body 1121 can block or open the retrieval opening. The fastener 1122 is slidably engaged with the window body 1121. The plate body 111 is provided with a limiting groove (not shown) for the fastener 1122 to be inserted. Specifically, the window body 1121 is the main component of the retrieval window 112, which is rotatably mounted on the plate body 111. This design allows users to quickly and conveniently open or close the retrieval opening without having to open the cover plate 14 and the transverse partition 15 from above to access the drawing tools in the second cavity 172, improving efficiency and convenience. The fastener 1122 is slidably engaged with the window body 1121 for locking or unlocking.

The first limiting member 42 and the second limiting member 43 can abut against the bottom of the drawing board, respectively, and can abut against the two sides of the drawing board that are opposite to each other along the first direction. Specifically, the rear plate 12, the support member 41, the first limiting member 42 and the second limiting member 43 together form a space for accommodating the drawing board, so that the drawing board can be firmly fixed in the mounting cavity 44, which is convenient for storage and easy to take out for use, greatly improving the convenience and efficiency of use. Moreover, the design of the mounting cavity 44 also makes full use of the multi-functional drawing cart 1. The structure of the 00 allows the drawing board to be efficiently stored together with other painting tools, improving the space utilization of the entire multi-functional painting cart 100. The main function of the support member 41 is to provide bottom support for the drawing board. When the drawing board is placed in the mounting cavity 44, the support member 41 can directly contact the bottom of the drawing board and provide stable support, preventing the drawing board from falling due to lack of support. The first limiting member 42 and the second limiting member 43 are respectively located on both sides of the drawing board that are arranged opposite each other in the left and right direction. By abutting against the sides of the drawing board, they limit the lateral movement of the drawing board and provide lateral limiting for the drawing board, ensuring that the drawing board remains stable in the mounting cavity 44 and does not sway left and right or back and forth. They also ensure that the drawing board remains stable throughout the transportation process, avoiding displacement or damage to the drawing board due to collisions or other external forces, further improving the safety of the drawing board. In this embodiment, the distance between the first limiting member 42 and the second limiting member 43 can be adjusted according to different sizes of drawing boards to accommodate different sizes of drawing boards, thereby increasing the flexibility and versatility of the multi-functional painting cart 100.

[0043] Please see Figure 1In one embodiment, the cover plate 14 is provided with a groove 141 for accommodating at least a portion of the structure of the drawing board. At least a portion of the structure of the drawing board can abut against the groove wall of the groove 141. The groove 141 extends along a second direction, and the number of grooves 141 is at least one. Specifically, when it is necessary to use the drawing board for painting, the drawing board can be tilted and placed on the cover plate 14, so that at least a portion of the lower end of the drawing board abuts against the groove wall of the groove 141, and the upper end of the drawing board abuts against the pull rod assembly 2, thereby fixing the drawing board and preventing it from moving at will, making it convenient for the user to paint. The number of grooves 141 is at least one, and multiple grooves 141 can be provided according to actual needs. Multiple grooves 141 can be spaced apart along the front-back direction to meet the needs of different tilt angles of the drawing board when painting. In this embodiment, the number of grooves 141 is three, and the three grooves 141 are spaced apart along the front-back direction.

[0044] Please see Figure 6 In one embodiment, the rear plate 12 includes a mounting member 121 and a vertical partition 122. The plate body 111 and the mounting member 121 are spaced apart along a first direction. The mounting member 121 is connected to the vertical partition 122. The mounting member 121 and the vertical partition 122 enclose each other to form a second receiving cavity 123 with a second opening 1231 at the top. The second receiving cavity 123 is used to receive drawing paper, and the second opening 1231 is used for drawing paper to enter and exit. The two ends of the two side plates 16 are respectively connected to the plate body 111 and the mounting member 121. The bottom plate 13, the plate body 111, the vertical partition 122, and the two side plates 16 enclose each other to form a first receiving cavity 17.
