Description

Technical Field

[0001] This utility model relates to the field of professional painting tools, specifically a professional painting tool with an adjustable angle. Background Technology

[0002] Because painters require different canvas angles when creating works using different techniques, fixed-angle painting tools not only hinder the control of fine brushstrokes but also easily cause physical fatigue due to prolonged posture. Therefore, it is generally necessary to use professional painting tools that are easy to adjust in angle for painting creation. Professional painting tools are stands used to support painting creation.

[0003] Existing technologies propose professional painting tools that are easy to adjust angles. However, when using them, the canvas or drawing board needs to be fixed to the easel panel. When the canvas angle needs to be adjusted, the angle of the painting tool is adjusted. However, since the easel panel and the support mechanism are fixed as one piece and cannot be separated, the operator needs to adjust the drawing board and the easel together, which is very troublesome. Not only is it easy to change the height while adjusting the angle, but the range of angle change is also limited, making it inconvenient to use.

[0004] Therefore, we propose a professional drawing tool that is easy to adjust the angle in order to solve the problems mentioned above. Utility Model Content

Rotating fixing bolt 13 can fix front support leg 11 and rear support leg 12, which is convenient for different users' habits, expands the scope of use, and makes it easy to use.

[0025] Please see Figures 1-5 Rotating holes 111 are provided through both sides of the front support leg 11. Coarse adjustment components 2 are rotatably installed in the rotating holes 111. The front support leg 11 has a mounting groove 112 inside. A mounting hole 113 is provided through the top of the mounting groove 112. A sliding hole 114 is provided through the inner side of the mounting groove 112. Fine adjustment components 3 are rotatably installed inside the mounting groove 112, the mounting hole 113, and the sliding hole 114.

[0026] The coarse adjustment component 2 includes a movable shaft 21 and connecting rods 22 fixedly installed on both sides of the movable shaft 21. The angle of the support plate 4 is changed by rotating the movable shaft 21. The other end of each connecting rod 22 is fixedly installed with a rotating shaft 23, and the rotating shaft 23 is rotatably installed inside the rotating hole 111. Rotating the rotating shaft 23 drives the movable shaft 21 to rotate. A thread is fixedly installed on the outer periphery of the rotating shaft 23 on one side. A fixing block 24 is installed on the outer periphery of the thread. By rotating the fixing block 24, the rotating shaft 23 is fixed relative to the front support leg 11, thus fixing the angle of the coarse adjustment component 2.

[0027] The fine-tuning component 3 includes a threaded rod 31 and an adjustment knob 32 fixedly mounted above the threaded rod 31. The threaded rod 31 is rotatably mounted inside the mounting hole 113. Rotating the adjustment knob 32 drives the threaded rod 31 to rotate. A moving block 33 is threadedly connected to the outer circumference of the threaded rod 31. The moving block 33 is movably mounted inside the mounting groove 112. Rotating the threaded rod 31 drives the moving block 33 to slide. A first connecting shaft 331 is fixedly mounted on the inner side of the moving block 33. The first connecting shaft 331 is rotatably mounted inside the support plate 4. A sliding shaft 34 is fixedly mounted in the mounting hole 113 on the other side. A sliding block 341 is slidably mounted on the outer circumference of the sliding shaft 34. A second connecting shaft 342 is fixedly mounted on the inner side of the sliding block 341. The second connecting shaft 342 is rotatably mounted inside the support plate 4. The movement of the support plate 4 drives the second connecting shaft 342 to slide. The sliding shaft 34 makes the movement of the moving block 33 more stable.

[0028] A movable hole 41 is provided through the interior of the support plate 4. A movable shaft 21 is movably installed inside the movable hole 41. The angle of the movable hole 41 is changed by the movement of the movable shaft 21. A rotating groove 411 is provided inside the support plate 4. A first connecting shaft 331 and a second connecting shaft 342 are rotatably installed in the rotating groove 411. The rotation of the first connecting shaft 331 drives the support plate 4 to move. A T-shaped sliding groove 412 is provided inside the support plate 4. A sliding column 42 is fixedly installed inside the T-shaped sliding groove 412. A T-shaped slider 43 is slidably installed on the outer periphery of the sliding column 42 and is slidably installed inside the T-shaped sliding groove 412. An upper baffle 431 is fixedly installed on the outer end of the T-shaped slider 43. The upper baffle 431 can slide up and down by the T-shaped slider 43, so that the upper baffle 431 and the lower baffle 5 can clamp the drawing board. A fixing button 44 is threaded inside the upper baffle 431. The position of the upper baffle 431 is fixed by rotating the fixing button 44, thereby fixing the drawing board.

[0029] Specifically, when it is necessary to adjust the angle of the drawing tool, the support plate 4 is rotated to allow the movable shaft 21 to move within the movable hole 41, thereby adjusting the drawing board within a general range. The connecting rod 22 is then rotated around the rotating shaft 23. Subsequently, the fixing block 24 is rotated to fix the angle of the coarse adjustment component 2. Then, the adjustment knob 32 is rotated to drive the moving block 33 to slide, causing the first connecting shaft 331 to push the support plate 4 to slide within the sliding hole 114, thereby changing the angle of the drawing board. At the same time, the angle adjustment range can be increased to meet the needs of painting from multiple angles.
