Description

Technical Field

[0001] The utility model belongs to the technical field of art education, in particular to an art education drawing board. Background Art

[0002] Art teaching drawing boards are tools used for teaching and practicing painting. They are usually made of hard materials with a smooth surface, suitable for using various painting tools. In art teaching, drawing boards can help students better master painting skills and practice different painting techniques such as sketching, watercolor, and oil painting.

[0003] In art teaching, when students lay drawing paper on the surface of the drawing board and do sketching, it is difficult for students to paint in the air because the drawing board is tilted. Therefore, they usually need a fulcrum to paint on. Especially for beginners, who are not proficient in the basics, how to form a fulcrum with their hands and paint steadily on this fulcrum is one of the most important basic steps.

[0004] At present, most people use the little finger joint to touch the drawing paper and use it as a fulcrum to paint. However, when sketching, pencils, charcoal pencils, etc. are usually used to draw on the surface of the drawing paper. After the fingers touch the drawing paper, they are often stained with pen dust. In this way, when the fulcrum needs to be replaced, the drawing paper will be contaminated by the pen dust on the surface of the fingers, often leaving difficult-to-eliminate black spots on the surface of the drawing paper, affecting the overall appearance. Frequent cleaning of the fingers will cause frequent friction and damage to the fingers, leading to finger injuries. In addition, it is difficult to ensure that only the little finger joint touches the drawing paper in the beginner state. Due to improper operation, the palm as a whole often touches the surface of the drawing paper, causing smearing, thereby contaminating a large area of ​​the painting and affecting subsequent painting.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 6As shown, the embodiment of the utility model provides an art education drawing board, including a drawing board body 1 and a base 2. The drawing board body 1 is made of wood, plastic or aluminum alloy, etc. The drawing board body 1 slides on the base 2. When painting is needed, the drawing board body 1 and the base 2 can be directly placed on the easel surface at the same time. It also includes a rotating plate 21 rotatably connected to the surface of the base 2. The surface of the rotating plate 21 is fixedly connected to a connecting piece 211. The surface of the connecting piece 211 is rotatably connected to a connecting ring 22. The surface of the connecting ring 22 is fixedly connected to a telescopic rod 23. The annular surface of the connecting ring 22 is fixedly connected to prevent telescopic rods from being stretched. The rod 23 directly contacts the stop block 221 of the drawing board body 1. Under the action of the stop block 221, the rotation of the connecting ring 22 is restricted. When the stop block 221 is pressed against the rotating plate 21, the telescopic rod 23 is in a parallel state with the drawing board body 1 and cannot continue to move toward the drawing board body 1. The output end of the telescopic rod 23 is hinged with a rotating block 24. A through hole is opened in the rotating block 24, and a pressing block 241 is passed through the through hole. The end of the pressing block 241 away from the drawing board body 1 is fixedly connected with a ring 242, and the surface of the rotating block 24 is provided with a cleaning component for wiping off dirt on the surface of the pressing block 241.

[0025] Specifically, the ring 242 is put on the little finger joint which is originally required to be against the surface of the drawing board body 1, and the ring 242 separates the little finger from the drawing board body 1 by a certain distance through the clamping block 241, thereby preventing the student's fingers from directly contacting the drawing board body 1 or the drawing paper on its surface, and the clamping block 241 can ensure support. At the same time, due to the setting of the stop block 221, when the stop block 221 is in contact with the surface of the rotating plate 21, the connecting ring 22 cannot continue to rotate toward one side of the drawing board body 1, thereby ensuring that the telescopic rod 23 will not be in contact with the surface of the drawing board body 1, which has a restrictive effect on the student's hand, allowing beginners to better grasp and control the degree of painting, and avoid the problem of palm contact with the drawing paper due to improper control, which causes the painting to be stained.

[0026] like Figure 4 As shown, further, in this embodiment, the cleaning assembly includes a plurality of spring clips 243 hinged on the surface of the rotating block 24, and the surfaces of both clamp arms of the spring clips 243 are provided with cleaning members.

[0027] Furthermore, the cleaning member includes two cleaning blocks 244 of comparable size. The cleaning blocks 244 are rubber blocks. When the two cleaning blocks 244 are combined, the through hole is completely covered and blocked. In the normal state, the spring clip 243 drives the two cleaning blocks 244 to contact and close each other, blocking the through hole. At this time, the pressing block 241 is restricted within the through hole. When painting is required, the pressing block 241 is moved forward by means of the collar 242. The pressing block 241 can push open the two closed cleaning blocks 244 and expand the spring clip 243. During this process, the cleaning blocks 244 will wipe off the dust on the surface of the pressing block 241 to avoid contaminating the drawing paper.

[0028] Wherein, grooves adapted to the pressing block 241 are provided on the surfaces of the two cleaning blocks 244. The provision of the grooves facilitates more comprehensive coverage of the surface of the pressing block 241, thereby wiping off the dust on the surface of the pressing block 241.

[0029] It should be noted that the pressing block 241 is limited to slide within the through hole and cannot be completely pulled out of the through hole, and thus separated from the rotating block 24.

[0030] As Figure 5 and Figure 6 shown, in a further embodiment, there is also a knocking assembly for vibrating the drawing board body 1 to make the carbon ash fall off. The knocking assembly includes a fixing block 3 fixedly connected to the surface of the base 2. A sliding groove is provided on the surface of the fixing block 3, and a knocking block 31 is slidably connected through the sliding groove. The knocking block 31 is made of wood, plastic or aluminum alloy. By colliding with the drawing board body 1, the drawing board body 1 can be vibrated, thereby shaking off the carbon ash adhered to the drawing paper on the surface of the drawing board body 1. The knocking block 31 is connected to the fixing block 3 through a spring B311. The two ends of the spring B311 are respectively fixedly connected to the knocking block 31 and the fixing block 3. A triggering assembly for triggering the knocking block 31 to knock on the drawing board body 1 is installed on one side of the base 2 close to the fixing block 3.

[0031] Wherein, the triggering assembly includes a connecting frame 32 slidably connected to one side of the base 2 close to the fixing block 3. The connecting frame 32 is in a "C" shape. Two limiting rods 321 are fixedly connected to the opposite sides of the two arms of the connecting frame 32, and the telescopic rod 23 is located between the two limiting rods 321. A clamping block 322 is fixedly connected to one side of the connecting frame 32 close to the fixing block 3. A clamping groove 312 adapted to the clamping block 322 is provided on the surface of the knocking block 31. In the normal state, the clamping block 322 is located within the clamping groove 312.

[0032] Specifically, when the telescopic rod 23 is in a parallel state with the drawing board body 1, the stop block 221 is pressed against the rotating plate 21, and the student is in a drawing state at this time. When a certain area is finished and the pencil or charcoal needs to be replaced, or the drawing area needs to be changed, the student will raise his hand and then pull the pressing block 241 outward through the ring 242, and then pull the entire telescopic rod 23 outward. With the rotating area of ​​the connecting ring 22 as the fulcrum, the telescopic rod 23 located on the hand moves outward, causing the telescopic rod 23 away from the hand end to move toward one side of the drawing board body 1, thereby driving the limit rod 321 to push the connecting frame 32 forward, causing the card block 322 to disengage from the card slot 312. Under the action of the rebound force of the spring B311, the knocking block 31 is ejected and collides with the drawing board body 1. The collision of the drawing board body 1 generates vibration, thereby shaking off the carbon ash, pen ash, etc. adhered to the surface of the drawing paper.

[0033] like Figure 2 As shown, further, in this embodiment, a slider 11 is fixedly connected to the bottom of the drawing board body 1, and a sliding groove adapted to the slider 11 is opened on the surface of the base 2. The slider 11 slides in the sliding groove, so that the drawing board body 1 can move horizontally a small distance in the sliding groove on the surface of the base 2.

[0034] Furthermore, a through rod 12 is fixedly connected to the side of the drawing board body 1 away from the connecting piece 211, and a groove matching the through rod 12 is opened on the surface of the base 2. The through rod 12 is inserted in the groove, and the through rod 12 is connected to the base 2 through a spring A13. The two ends of the spring A13 are respectively fixedly connected to the through rod 12 and the base 2. The spring A13 is provided, and the drawing board body 1 slides in the slide groove with the help of the slider 11. When the side wall of the drawing board body 1 away from the spring A13 is hit, the entire drawing board body 1 can be shaken back and forth by the rebound force of the spring A13, generating vibration, and helping to shake off the pen dust and carbon dust attached to the surface of the drawing paper. It should be noted that the back and forth shaking of the drawing board body 1 is only a small-amplitude micro-displacement shaking, which does not affect the subsequent normal painting.

[0035] Working principle:

[0036] The drawing board body 1 together with the bottom base 2 is placed on the easel surface. If necessary, the drawing board body 1 can be fixed by clamping or other means. Before painting, the student can put the ring 242 on the little finger joint to pick up a pencil or charcoal to paint. When painting, the hand is close to the drawing board body 1, and the telescopic rod 23 will rotate toward the drawing board body 1 with the connecting ring 22 as the rotation point until the stop block 221 rotates to abut against the surface of the rotating plate 21, thereby positioning the telescopic rod 23. Since the telescopic rod 23 is positioned, the student wants to continue to move the hand forward at this time The student's fingers are restricted and can only move forward by pushing the ring 242, driving the clamping block 241 to move forward from the through hole, and pushing the cleaning block 244 to both sides to expand the spring clip 243. During this process, the cleaning block 244 will wipe off the dust on the surface of the clamping block 241. Then, after the cleaning block 244 is completely pushed away, the clamping block 241 moves forward to the drawing paper against the surface of the drawing board body 1, and the student's fingers are separated from the drawing paper by the clamping block 241 by a certain distance, forming a fulcrum while preventing the fingers from directly contacting the drawing paper, thereby reducing the number of times the hands rub or contact the drawing paper.

[0037] In addition, when it is necessary to replace the paintbrush or change the painting area, the student can lift his hand and use the ring 242 to pull the clamping block 241 outward, so that the head of the clamping block 241 moves backward toward the through hole until it retracts into the through hole. Under the rebound force of the spring clip 243, the two cleaning blocks 244 return to the normal position to block the through hole. At this time, the hand that continues to lift up and the ring 242 continue to move upward, driving the telescopic rod 23 to rotate with the connecting ring 22 as the fulcrum, and the other end of the telescopic rod 23 pushes the limit rod 321 forward, so that the connecting frame 32 moves forward synchronously, and then the card block 322 is disengaged from the card slot 312. Under the rebound force of the spring B311, the knocking block 31 is ejected and knocks the drawing board body 1, and cooperates with the spring A13 on the other side to make the drawing board body 1 vibrate slightly, thereby shaking off the pen dust or carbon dust on the drawing paper on the surface of the drawing board body 1.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
