Description

Technical Field

[0001] This utility model relates to the field of drawing board technology, and in particular to a multifunctional art drawing board. Background Technology

[0002] In art and design, drawing boards are often used to place and fix drawing paper, which facilitates the drawing process. However, there are still some shortcomings in actual operation. For example, drawing boards used in art and design often have a simple structure and can only fix drawing paper of a single size.

[0003] A current multifunctional art drawing board, with publication number CN221417841U, allows users to adjust the height of the electric lifting table legs by pressing a control button. The height of the drawing board mounting box can be adjusted according to the user's needs. After adjustment, the length of the connecting rod within the connecting sleeve is adjusted by loosening the adjusting bolts, allowing the connecting rod to engage in the slot. After adjusting the angle of the drawing board support, the drawing board is inserted into the inverted L-shaped slot. By pulling the drawer handle, the sliding block at the bottom of the drawer box slides within the sliding groove, allowing the drawer box to be pulled out and the art supplies to be retrieved.

[0004] Although the device can adjust the height and angle of the drawing board and support it using an inverted L-shaped groove, it still requires a more traditional method (such as paper pasting) to fix different sizes of drawing paper to the front of the drawing board. This method is complicated to operate and can easily damage the paper. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figure 1-4 As shown, a multifunctional art drawing board includes a drawing board 1. Two insert rods 14 are slidably inserted into both sides of the drawing board 1. An L-shaped rod 4 is fixedly connected to the other end of the insert rod 14. The bent edges of the two L-shaped rods 4 located on the same side of the drawing board 1 are fixedly connected to a sliding groove plate 3 located on the front of the drawing board 1 and parallel to the drawing board 1. The groove of the sliding groove plate 3 faces the drawing board 1, and a spring rod 15 is fixedly connected inside the sliding groove plate 3. The telescopic end of the spring rod 15 is fixedly connected to a pressure plate 18 that is slidably connected to the sliding groove plate 3 and is used to press and fix the drawing paper. The insert rods 14 are provided with limiting slots 7 that are linearly arrayed along the length direction of the insert rods 14. Cards 16 for engaging with the limiting slots 7 are slidably connected to both sides of the drawing board 1.

[0023] In this technical solution, the insertion rod 14 is slidably inserted into the drawing board 1, so that the insertion rod 14 can move relative to the drawing board 1, thereby driving the L-shaped rod 4, the sliding plate 3 and other components connected to it to adjust their positions. The sliding plate 3 is fixed on the front and parallel position of the drawing board 1 by the L-shaped rod 4, which provides a structural basis for fixing the drawing paper later.

[0024] The spring rod 15 and the pressure plate 18 inside the slide plate 3 cooperate with each other. The extension and retraction characteristics of the spring rod 15 enable the pressure plate 18 to exert a squeezing effect on the drawing paper, thereby fixing the drawing paper and preventing the drawing paper from moving during the painting process and affecting the painting effect.

[0025] The limiting slot 7 on the insertion rod 14 and the cards 16 on both sides of the drawing board 1 engage with each other. When the insertion rod 14 is adjusted to the appropriate position, the cards 16 engage with the limiting slot 7, which can lock the position of the insertion rod 14, ensuring the stability of the slide plate 3 and the pressure plate 18 when fixing the drawing paper, and also making it convenient for users to adjust the fixing position of the drawing paper according to actual needs.

[0026] like Figure 4 As shown, the card 16 has guide sleeves 19 fixedly connected to the drawing board 1 at both ends. Guide grooves 17 are provided on the opposite sides of the two guide sleeves 19 that are close to each other. The card 16 is slidably connected to the guide sleeves 19 through the guide grooves 17.

[0027] In this technical solution, the guide sleeve 19 and guide groove 17 provide a stable track for the sliding of the card 16. When the position of the insertion rod 14 needs to be adjusted, the card 16 is slid to disengage from the limiting groove 7. After the insertion rod 14 is adjusted to the appropriate position, the card 16 can be re-inserted into the corresponding limiting groove 7 to achieve a stable lock on the position of the insertion rod 14, thereby ensuring the reliability of the slide plate 3 and the pressure plate 18 when fixing the drawing paper.

[0028] like Figure 2 As shown, it also includes a drawing board base 2. Support rods 6 are provided on both sides of the top of the drawing board base 2. Two connecting rods 12 are provided between the two support rods 6. The two connecting rods 12 are located at both ends of the support rods 6 respectively. One connecting rod 12 is rotatably connected to the two support rods 6, and the other connecting rod 12 is fixedly connected to the two support rods 6. Mounting seats 13 are fixedly connected to both ends of one of the connecting rods 12 on both sides of the middle of the back of the drawing board 1.

[0029] In this technical solution, the support rod 6 and the connecting rod 12 form the basic support and rotation structure of the drawing board 1. The two support rods 6 are connected to each other through the connecting rod 12, which enhances the stability of the overall structure. By setting one of the connecting rods 12, the drawing board 1 can rotate around the support rod 6 through the connecting rod 12. Users can adjust the tilt angle of the drawing board 1 according to their own painting habits and actual needs. By setting the hidden groove 5, when the drawing board 1 is not needed, the support rod 6 rotates relative to the drawing board base 2 through the other connecting rod 12 and then rotates into the hidden groove 5, reducing the space occupied.

[0030] like Figure 2 As shown, a connecting plate 9 is fixedly connected between the two support rods 6. A motor 10 is fixedly connected to both the connecting plate 9 and the drawing board base 2. Gears 11 are fixedly connected to the main shaft of the motor 10 and the connecting rod 12. The gears 11 on the two motors 10 mesh with the gears 11 on the two connecting rods 12 respectively.

[0031] In this technical solution, when the motor 10 starts, the gear 11 on its main shaft will rotate accordingly. Since the gear 11 on the motor 10 meshes with the gear 11 on the connecting rod 12, the rotation of the main shaft of the motor 10 will drive the connecting rod 12 to rotate through the gear 11, so that the angle adjustment of the drawing board 1 and the support rod 6 can be automated.

[0032] like Figure 2 As shown, the top of the drawing board base 2 has a storage cavity 8 located between two hidden slots 5.

[0033] Working principle: When fixing drawing paper of different sizes, according to the size of the drawing paper, first slide the card 16 to disengage it from the limiting slot 7 on the insert rod 14, then move the insert rod 14 to drive the L-shaped rod 4 and the slide plate 3 to change position. After adjusting to the appropriate position, release the card 16 so that it is inserted into the corresponding limiting slot 7 to lock the position of the insert rod 14. Then, place the drawing paper directly on the drawing board 1. The spring rod 15 in the slide plate 3 pushes the pressure plate 18 to squeeze the drawing paper, thus completing the fixing of the drawing paper.

[0034] The wiring diagram of the motor 10 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor 10 will not be explained in detail.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
