[0002] In the field of art creation and design, a large number of creators still prefer to use paper to perform traditional painting on a drawing board. Existing drawing boards have many deficiencies when adapting to the paper painting scenario. Traditional drawing boards are mostly single-plane structures and lack effective paper fixing devices. Creators often need to use auxiliary tools such as clips and tapes to fix the paper, which not only makes the operation cumbersome but also easily leaves clip marks or glue stains on the paper, affecting the painting effect.

[0003] In the prior art, for example, a drawing board in the patent with the authorization announcement number CN221892901U includes a substrate and two groups of paper pressing devices arranged on both sides of the substrate.

[0014] The present invention provides a product design drawing board that is convenient to adjust. Compared with the prior art, it has the following beneficial effects: 1. For this product design drawing board that is convenient to adjust, when it is necessary to fix the drawing paper on the surface of the drawing placement board, first place the drawing paper on the surface of the drawing placement board. According to the length of the drawing paper, start the motor, and its output shaft drives the bidirectional screw rod to rotate. Under the action of the bidirectional screw rod, the two moving sliders move towards or away from each other. The moving slider drives the sliding bevel gear to slide along the second rotating rod and the slide bar through the first connecting plate.

Detailed implementation manners

[0019] 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 of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] The present invention provides two technical solutions: Figures 1-8 The first implementation manner is shown: A product design drawing board that is convenient to adjust, including a mobile lifting component 1, an angle adjustment component 2 is arranged at the output end of the mobile lifting component 1, and a fixing component 3 is arranged at the top end of the angle adjustment component 2; The mobile lifting component 1 includes a first housing 14, and a threaded lead screw 15 is rotatably installed on the inner wall of the first housing 14; The angle adjustment component 2 includes a lifting plate 21, a first bracket 22 is fixedly installed at the top end of the lifting plate 21, and a first rotating rod 23 is rotatably installed on the inner wall of the first bracket 22; The fixing component 3 includes a painting placement board 31. At the top end of the painting placement board 31, a second support 36 is fixedly installed. Inside the inner wall of the second support 36, a second rotating rod 37 is rotatably installed. On the outer wall of the second rotating rod 37, two sliding strips 38 are fixedly installed. On the outer walls of the second rotating rod 37 and the two sliding strips 38, two sliding bevel gears 310 are slidably arranged. The sliding bevel gears 310 can slide on the surface of the second rotating rod 37, and under the action of the sliding strips 38, when the second rotating rod 37 rotates, it can drive the sliding bevel gears 310 to rotate. On the outer walls of the two sliding bevel gears 310, a rotating bevel gear 312 is meshed. On one side of the outer wall of the rotating bevel gear 312, a rotating pressing plate 314 is arranged.

[0021] One end of the outer wall of the first rotating rod 23 penetrates through the outer wall of the first support 22 and is fixedly installed with a worm gear 24. On the outer wall of the worm gear 24, a worm 25 is meshed. On the outer wall of the first support 22, a mounting frame 26 is fixedly installed. The two ends of the outer wall of the worm 25 are rotatably installed inside the inner wall of the mounting frame 26. When the worm 25 rotates, it can drive the worm gear 24 to rotate. Thus, the worm gear 24 can drive the first rotating rod 23 to rotate, and the worm gear 24 and the worm 25 have self-locking property, which can prevent the worm gear 24 from rotating randomly after rotation.

[0022] One end of the outer wall of the worm 25 penetrates through the outer wall of the mounting frame 26 and is fixedly installed with a rocker 27. On the outer wall of the first rotating rod 23, two connecting blocks 28 are fixedly sleeved. The top ends of the two connecting blocks 28 are fixedly connected to the painting placement board 31. The rocker 27 can drive the worm 25 to rotate, the first rotating rod 23 can drive the two connecting blocks 28 to rotate, and the connecting blocks 28 can further drive the painting placement board 31 to adjust the angle.

[0023] The moving and lifting component 1 further includes a moving bottom plate 11. At the bottom end of the moving bottom plate 11, a set of universal wheels 12 are fixedly installed. At the top end of the moving bottom plate 11, a bottom frame 13 is fixedly installed. The bottom frame 13 is fixedly connected to the first machine shell 14. The bottom end of the threaded lead screw 15 penetrates to the bottom end of the bottom frame 13 and is fixedly installed with a first rotating plate 16. The first rotating plate 16 can drive the threaded lead screw 15 to rotate.

[0024] Figures 1-8 The second implementation manner is shown. The main difference from the first implementation manner is that: a connecting slider 17 is threadedly connected to the outer wall of the threaded lead screw 15. The connecting slider 17 is movably inserted into the inner wall of the first machine shell 14. The connecting slider 17 is fixedly connected to the lifting plate 21.

[0025] A second housing 32 is fixedly installed at the top of the painting placement board 31. A bidirectional screw 33 is rotatably installed on the inner wall of the second housing 32. Two moving sliders 34 are threadedly connected to the outer wall of the bidirectional screw 33. Both of the two moving sliders 34 are movably inserted into the inner wall of the second housing 32. By rotating the bidirectional screw 33, the two moving sliders 34 can be driven to move away from or close to each other.

[0026] A first connecting plate 39 is fixedly installed on the outer wall of the moving slider 34. One side of the outer wall of the first connecting plate 39 is rotatably connected to a sliding bevel gear 310. One end of the outer wall of the second housing 32 is fixedly installed with a motor 35. The output shaft of the motor 35 penetrates the inner wall of the second housing 32 and is fixedly connected to one end of the outer wall of the bidirectional screw 33. When the moving slider 34 moves, the sliding bevel gear 310 can be driven to move through the first connecting plate 39.

[0027] A connecting frame 311 is fixedly installed on the outer wall of the moving slider 34. When the moving slider 34 moves, the rotating bevel gear 312 can be driven to move through the connecting frame 311. A third rotating rod 313 is rotatably installed on the outer wall of the connecting frame 311. One end of the outer wall of the third rotating rod 313 is fixedly connected to the rotating bevel gear 312. The outer wall of the third rotating rod 313 is fixedly connected to a rotating pressing plate 314. When the rotating pressing plate 314 rotates, the drawing paper below can be pressed tightly, which is convenient for drawing. One end of the outer wall of the second rotating rod 37 penetrates the outer wall of the second bracket 36 and is fixedly installed with a second rotating plate 315.

[0028] Meanwhile, the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0029] During operation, first move the device to a suitable position through the universal wheels 12. When the height of the painting placement board 31 needs to be adjusted, rotate the first rotating plate 16 to drive the threaded screw rod 15 to rotate. Since the connecting slider 17 is threadedly connected to the threaded screw rod 15 and is movably inserted into the inner wall of the first housing 14, the rotation of the threaded screw rod 15 causes the connecting slider 17 to move up and down along the inner wall of the first housing 14, thereby driving the lifting plate 21 fixedly connected to the connecting slider 17 to achieve height adjustment, so as to adapt to users of different heights and improve the practicability of the device. When the drawing paper needs to be fixed on the surface of the painting placement board 31, first place the drawing paper on the surface of the painting placement board 31. According to the length of the drawing paper, start the motor 35, and its output shaft drives the bidirectional screw rod 33 to rotate. The two moving sliders 34 move towards or away from each other under the action of the bidirectional screw rod 33. The moving slider 34 drives the sliding bevel gear 310 to slide along the second rotating rod 37 and the slide bar 38 through the first connecting plate 39. At the same time, rotating the second rotating plate 315 can make the second rotating rod 37 rotate. The sliding bevel gear 310 and the rotating bevel gear 312 always remain meshed. The rotating bevel gear 312 drives the third rotating rod 313 and the rotating pressure plate 314 to rotate, realizing the clamping and loosening of the paper. Due to the coordinated work of the movement of the moving slider 34 and the rotation of the rotating pressure plate 314, different-sized papers can be fixed quickly and evenly. In the fixing assembly 3, the motor 35 drives the bidirectional screw rod 33 to drive the moving sliders 34 to move synchronously. With the transmission of the sliding bevel gear 310 and the rotating bevel gear 312, the rapid synchronous adjustment of the two rotating pressure plates 314 can be realized. Compared with the traditional painting board that requires multiple manual adjustments of the pressure plate, the efficiency of paper fixing is greatly improved, and the time waste caused by repeated adjustments is avoided. When the angle of the painting placement board 31 needs to be adjusted, rotate the rocker 27 to drive the worm 25 to rotate. The worm 25 meshes with the worm gear 24, so that the worm gear 24 drives the first rotating rod 23 to rotate. The connecting block 28 fixed to the outer wall of the first rotating rod 23 is fixed to the painting placement board 31, thereby realizing the adjustment of the angle of the painting placement board 31 to adapt to the usage habits and painting needs of different creators.
