Description

Technical Field

[0001] The present invention relates to the technical field of painting devices, and particularly to a multifunctional drawing board for cultural and creative design. Background Art

[0002] Cultural and creativity refers to creating new ideas in the cultural field, or the achievements of cultural innovation; its core is "creativity", that is, "human creativity" and "maximizing human creativity", and "creativity" is the ability to produce new things; these ideas must be unique, original and meaningful;

[0003] In terms of art, painting is an act of adding colors on a surface as a support. Examples of those surfaces include paper, canvas, wood, glass, lacquerware or concrete, etc. At the level of art terms, the meaning of painting also includes using this art act plus graphics, composition and other aesthetic methods to achieve the concepts and meanings that the practitioners hope to express. Painting is the most important art form in plastic arts. It refers to the art form that uses artistic languages such as lines, colors and shapes, and through artistic means such as modeling, color and composition, creates static visual images in a two-dimensional space to express the author's aesthetic feelings; Painting often has outdoor operations, and auxiliary tools such as drawing boards are usually needed when painting outdoors.

[0004] 1. In real life, the environment for painters to paint may be indoors or outdoors. When painters are sketching outdoors, due to geographical environment, it is very difficult for the drawing board to ensure that it is on a flat horizontal plane. And general drawing boards can only adjust the angle of a single axis. The actual outdoor use scenarios are more complex. When the drawing board does not have the ability to adjust at multiple angles, the drawing board may be in an inclined state, which will make it difficult for painters to work on the drawing board;

[0005] 2. During the painting process, painters will place other painting materials in front of them for convenient use during the painting creation process, which requires leaving a placement space between the drawing board and in front of the painter. However, the position between the conventional drawing board and the easel is fixed, and when the painter is operating in front of the drawing board, the distance between the easel and the painter is also small, making it difficult to leave a suitable space to place other materials, and it is not convenient during use;

[0006] 3. During the design and painting process, in order to better observe the sketching environment, painters may carry out painting work at different positions. For example, when the painting object is a wide view, it is better for the painter to stand to observe the environment, and when the painting object is a close view, it is more comfortable for the painter to sit. Therefore, when the height of the drawing board cannot be adjusted according to the usage requirements of the scene, it is difficult to meet the operation requirements of painters.

Detailed implementation manner

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0036] Please refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 ,a multifunctional drawing board for cultural and creative design, a multifunctional drawing board for cultural and creative design, including a support frame 1 and a rotating assembly 2. A rotating assembly 2 for adjusting the direction is provided at the top of the support frame 1. The rotating assembly 2 includes a rotating ball 201, a rotating ring 202, a fixed shaft 203, a support frame 204, a connection hole 205, a sleeve 206, a fixed rod 207 and a through hole 208. A rotating ring 202 is sleeved on the outer wall of the rotating ball 201. A fixed shaft 203 is provided in the middle of the rotating ball 201. Support frames 204 are provided at both ends of the fixed shaft 203. Connection holes 205 are opened at the corresponding positions of the outer wall of the support frame 204 and the fixed shaft 203. A sleeve 206 is provided on the outer wall of the rotating ring 202. A fixed rod 207 is provided inside the sleeve 206. Through holes 208 are opened at the corresponding positions of the outer wall of the rotating ring 202 and the fixed rod 207;

[0037] The specific operation is as follows. When adjusting the angle of the drawing board 6, first manually rotate the fixing rod 207 to change its position inside the sleeve 206, so that the fixing rod 207 is away from the outer wall of the rotating ball 201. At this time, the rotating ring 202 and the rotating ball 201 are in a loose state, and the position of the rotating ring 202 can be adjusted and changed. The position of the rotating ball 201 is in an absolute state under the action of the fixing shaft 203 and the support frame 204. After adjusting the rotating ring 202 to a suitable position angle, manually rotate the fixing rod 207 to make it close to the outer wall of the rotating ball 201 and apply pressure to it, so that the positions of the rotating ring 202 and the rotating ball 201 are in a stable state. By setting the rotating assembly 2 in the present invention, the user can change the connection state of the rotating ring 202 and the rotating ball 201 by rotating the fixing rod 207, and then the user can adjust the angle of the drawing board 6 by changing the position of the rotating ring 202 on the surface of the rotating ball 201;

[0038] Among them, the rotating ball 201 is fixedly connected to the fixing shaft 203, the sleeve 206 is threadedly connected to the fixing rod 207, the inner diameter of the rotating ring 202 is larger than the outer diameter of the rotating ball 201, the inner diameter of the support frame 204 is larger than the outer diameter of the rotating ring 202, the rotating ball 201 is in a spherical state, and the rotating ring 202 can rotate at multiple angles and in multiple axial directions on its surface. Therefore, the drawing board 6 can be adjusted at multiple angles in the space environment, meeting the needs of the user for multi-scene use. Even when the ground is uneven, the inclination state of the drawing board 6 can also be adjusted;

[0039] It should be particularly noted that the outer wall of the rotating ball 201 is engraved with a groove whose size matches the diameter of the fixing rod 207. When the fixing rod 207 applies pressure to the outer wall of the rotating ball 201, the groove on the outer wall of the rotating ball 201 can better limit the fixing rod 207 to prevent the position from sliding and causing the rotating ring 202 and the rotating ball 201 to fall off;

[0040] Please refer to Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10, on the side of the outer wall of the rotating ring 202 away from the sleeve 206, there is a telescopic component 3 for length adjustment. The telescopic component 3 includes a sliding cylinder 301, a sliding rod 302, a sliding groove 303, and a limiting sleeve 304. Inside the sliding cylinder 301, there is a sliding rod 302. At the corresponding position of the sliding cylinder 301 and the sliding rod 302 inside, there is a sliding groove 303. The outer wall of the sliding cylinder 301 is sleeved with a limiting sleeve 304. The telescopic component 3 further includes a rotating shaft 305, a rotating groove 306, a lever 307, and a limiting block 308. Inside the limiting sleeve 304, there is a rotating shaft 305. At the corresponding position of the limiting sleeve 304 and the rotating shaft 305 inside, there is a rotating groove 306. At the top of the outer wall of the rotating shaft 305, there is a lever 307. Below the rotating shaft 305, there is a limiting block 308. The telescopic component 3 further includes a spring 309, a fixing hole 310, a first limiting groove 311, and a second limiting groove 312. At the connection between the limiting sleeve 304 and the limiting block 308, there is a spring 309. At the connection between the inner wall of the limiting sleeve 304 and the spring 309, there is a fixing hole 310. At the corresponding position of the outer wall of the sliding cylinder 301 and the limiting block 308, there is a first limiting groove 311. At the corresponding position of the outer wall of the sliding rod 302 and the limiting block 308, there is a second limiting groove 312;

[0041] The operation is as follows. Manually change the position of the lever 307, so that the rotating shaft 305 makes an eccentric motion in the rotating groove 306. The rotating shaft 305 relieves the pressure on the surface of the limiting block 308. The limiting block 308 is affected by the elastic force of the spring 309 and sinks into the inside of the limiting sleeve 304 by itself, and relieves the pressure on the sliding rod 302, making the positions of the sliding cylinder 301 and the sliding rod 302 loose. Then the user manually pushes and pulls the drawing board 6 to change the positions of the sliding cylinder 301 and the sliding rod 302. After adjusting to the appropriate position, then manually restore the position of the lever 307, so that the limiting block 308 presses against the second limiting groove 312 on the outer wall surface of the sliding rod 302 through the first limiting groove 311, exerting pressure on it, so that the positions of the sliding cylinder 301 and the sliding rod 302 are fixed again. By setting the telescopic component 3, the spatial distance between the drawing board 6 and the flower stand can be extended. When the user sits in front of the drawing board 6 to paint, it is convenient to place painting materials such as paint boxes, paintbrushes, etc. in front of the body for use during painting;

[0042] Among them, the limiting block 308 is elastically connected to the limiting sleeve 304, the rotating shaft 305 is rotatably connected to the limiting sleeve 304, and the connection between the rotating shaft 305 and the limiting sleeve 304 is located at the eccentric point of the outer wall of the rotating shaft 305;

[0043] It should be particularly noted that the telescopic component 3 is installed on the rotating component 2. When the user adjusts the rotating component 2, by operating the telescopic component 3 to borrow force, it can be better used. And manually adjusting the position of the lever 307 can separate the sliding cylinder 301 and the sliding rod 302, so that the drawing board 6 is separated from the flower stand, which is convenient for carrying and transporting;

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 11 and Figure 12 Figure 12 , the bottom of the support frame 1 is provided with a lifting assembly 4 for height adjustment. The lifting assembly 4 includes a moving cylinder 401, a support rod 402, a base 403 and a moving ring 404. A support rod 402 is arranged inside the moving cylinder 401. A base 403 is arranged at the bottom of the support rod 402. A moving ring 404 is arranged inside the support rod 402. The lifting assembly 4 further includes a connecting rod 405, a moving rod 406, a first bevel gear 407 and a second bevel gear 408. A connecting rod 405 is arranged at the connection between the inner wall of the support rod 402 and the moving ring 404. A moving rod 406 is arranged inside the moving ring 404. A first bevel gear 407 is arranged at the top of the moving rod 406. A second bevel gear 408 is arranged on the outer wall of the first bevel gear 407. The lifting assembly 4 further includes a connecting shaft 409, a rocker 410, a bearing 411 and a mounting hole 412. A connecting shaft 409 is arranged in the middle of the second bevel gear 408. A rocker 410 is arranged on the side of the connecting shaft 409 away from the second bevel gear 408. A bearing 411 is sleeved on the outer wall of the connecting shaft 409. A mounting hole 412 is opened at the position corresponding to the bearing 411 on the outer wall of the moving cylinder 401. A painting board 6 is arranged on the side of the sliding rod 302 away from the sliding cylinder 301. A connecting piece 5 is arranged at the connection between the painting board 6 and the sliding rod 302;

[0045] The operation is as follows. When the height of the painting board 6 needs to be adjusted, first rotate the rocker arm 410, so that the connecting shaft 409 rotates inside the bearing 411, driving the second bevel gear 408 to rotate, thereby causing the first bevel gear 407 to rotate, that is, driving the moving rod 406 to rotate in the moving ring 404, that is, the moving rod 406 rises in the moving ring 404, driving the moving cylinder 401 to rise, away from the support rod 402 and the base 403. When the height is appropriate, stop rotating the rocker arm 410. When the height needs to be lowered, rotate the rocker arm 410 in the opposite direction. By arranging the lifting assembly 4 at the bottom of the support frame 1, the user can adjust the height of the painting board 6 by rotating the rocker arm 410, meeting the usage requirements of different painting states of the user. Moreover, the rocker arm 410 is a labor-saving structure, facilitating the operation of the user;

[0046] Among them, the meshing state of the first bevel gear 407 and the second bevel gear 408 can make the moving cylinder 401 in a stable state after height adjustment.

[0047] Working principle: When the angle of the drawing board 6 needs to be adjusted, first manually rotate the fixed rod 207 to change its position inside the sleeve 206, so that the fixed rod 207 is away from the outer wall of the rotating ball 201. At this time, the rotating ring 202 and the rotating ball 201 are in a loose state, and the position of the rotating ring 202 can be adjusted and changed. The position of the rotating ball 201 and the support frame 204 are in an absolute state under the action of the fixed shaft 203. After adjusting the rotating ring 202 to the appropriate position angle, manually rotate the fixed rod 207 to make it close to the outer wall of the rotating ball 201 and apply pressure to it, so that the positions of the rotating ring 202 and the rotating ball 201 are in a stable state. Then manually change the position of the lever 307, so that the rotating shaft 305 makes an eccentric movement in the rotating groove 306. The rotating shaft 305 releases the pressure on the surface of the limiting block 308. The limiting block 308 is affected by the elastic force of the spring 309 and sinks into the limiting sleeve 304 by itself, and releases the pressure on the sliding rod 302, so that the positions of the sliding cylinder 301 and the sliding rod 302 are loose. Then the user manually pushes and pulls the drawing board 6 to change the positions of the sliding cylinder 301 and the sliding rod 302. After adjusting to the appropriate position, then manually restore the position of the lever 307, so that the limiting block 308 closely adheres to the second limiting groove 312 on the outer wall surface of the sliding rod 302 through the first limiting groove 311 and applies pressure to it, so that the positions of the sliding cylinder 301 and the sliding rod 302 are fixed again. Finally, when the height of the drawing board 6 needs to be adjusted, first rotate the rocker 410, so that the connecting shaft 409 rotates inside the bearing 411, driving the second bevel gear 408 to rotate, so that the first bevel gear 407 rotates, that is, driving the moving rod 406 to rotate in the moving ring 404, that is, the moving rod 406 rises in the moving ring 404, driving the moving cylinder 401 to rise and move away from the support rod 402 and the base 403. When the height is appropriate, stop rotating the rocker 410. When the height needs to be lowered, rotate the rocker 410 in the reverse direction. The above is the working principle.

[0048] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
