Description

Technical Field

[0001] The utility model relates to the technical field of mechanical design, in particular to a portable outdoor painting tool box. Background Art

[0002] In the process of art painting creation, it is often necessary to go outdoors for sketching and field painting to get inspiration, but when painting, you will need to use easels, various tools and other items. If you go out for sketching, it is inconvenient to carry too many things and the easel is relatively large. At this time, you need a storage tool that can combine the easel, painting tools, etc. into one and is easy to carry.

[0003] In response to this technical problem, some patents have been designed to store art tools in a trolley suitcase style with a publication number. For example, the new patent with a publication number of CN218616057U designs a trolley suitcase for art, but does not combine it with a drawing board, and you have to bring a drawing board separately, which lacks portability. There is also a design that combines a drawing board and a suitcase, such as the Chinese utility model patent with a publication number of CN216940631U, which combines an art drawing board with a suitcase. Although the drawing board and some tools can be stored in the toolbox, some inconveniences in carrying are reduced. However, in the application scenario where the toolbox needs to be lifted for creation during the painting process, and sketching is a long process, the design of combining the suitcase with the drawing board is not friendly to creators with weak arm strength. It takes a lot of arm strength to lift the drawing board, which affects the creation and requires frequent putting down of the drawing board for rest and adjustment. At the same time, the poor stability of the painting support will affect the quality of the painting. In addition, based on the need for seats by some painters when painting, it is also crucial to carry the drawing board and chair while occupying the least space in the tool box. Therefore, it is necessary to develop a simple and convenient design that can maintain the drawing board at a certain height during the painting process and has high stability, so that the painters can create without restraint.

Preferably, the universal wheel 18 and the support column 19 have the same height.

[0042] In the specific implementation process, when the portable outdoor painting tool box is not needed, the retractable double pull rod 2 is moved downward, and the retractable double pull rod 2 will be lowered with the drawing board 3 through the cross bar 5 fixedly connected thereto, and finally put into the suitcase for easy storage. When painting outdoors, the retractable double pull rod 2 can be pulled up and moved upward, so that the drawing board 3 extends out of the upper part of the box body 1. At this time, the drawing board 3 is rotated, driving the linear bearing 52 to rotate, so that the drawing board 3 can realize fixed axis rotation.

[0043] When the drawing board 3 needs to be fixed, the drawing board 3 can adjust its vertical position by lifting the retractable double pull rod 2, and screwing the limiter 4 threadedly connected to it to fix the vertical position of the drawing board 3; at the same time, the two drawing board feet 31 below the drawing board 3 are inserted into the foot limit holes 81 at different positions to adjust the tilt angle of the drawing board 3 when it is fixed, which meets the needs of different painters for different painting postures. At the same time, because the foot limit hole 81 is an inclined design, and the limiter 4 is set at the connection between the retractable double pull rod 2 and the box body 1, when the retractable double pull rod 2 is pulled out to the required height, the limiter 4 can clamp the retractable double pull rod 2, so that the retractable double pull rod will not slide up and down, and any height limit can be achieved. Therefore, after the drawing board feet 31 are inserted into the foot limit holes 81, the drawing board 3 will be fixed.

[0044] In order to meet the user's demand for stability of the toolbox when painting, this design is equipped with universal wheels 18 and support columns 19 under the box body 1. The design of the lockable universal wheels 18 makes it easy for the user to move the toolbox, and can be locked to prevent the box body 1 from moving accidentally; the support columns 19 help the user prevent the toolbox from moving accidentally when painting or other situations where the toolbox does not need to be moved, and have strong stability and safety.

The insertion of the rotating support column 95 into the hole opened in the side wall of the box body 1 can keep the water cup nesting ring 11 level.

[0052] In the specific implementation process, under normal painting conditions, since the fixed concave disc 92 is movably connected to the first guide block 91, the user can rotate the fixed concave disc 92 from a vertical position to a horizontal position, and then the first guide block 91 and the rotating support column 95 on the back lock the fixed concave disc 92 in a horizontal state. At this time, the user can add paint to the second groove 94 of the palette 93 to facilitate mixing and dipping; furthermore, the user can temporarily place tools such as a brush on the upper surface of the palette 93. Preferably, the palette 93 is plugged into the fixed concave disc 92 to stabilize the palette 93 so that it is not accidentally touched and overturned; and after the painting is finished, the palette 93 can be easily disassembled and cleaned. The water cup nesting ring 11 also uses the movable connection of the second guide block 10 to rotate the water cup nesting ring 11 to a horizontal state and then use the rotating support column 95 on the back to provide support, which is convenient for storing clean water needed for color mixing and cleaning.
