[0001] This utility model relates to the field of drawing tools, and in particular to a drawing tool. Background Technology

[0002] Many drawing tools are used in vocational school mathematics teaching, and the drawing board is one of them. A mathematical drawing blackboard is a tool used to display and demonstrate mathematical problems and solutions.

[0003] The published patent document with publication number CN221892864U discloses a drawing board for mathematics teaching, including a base plate. The bottom of the base plate is provided with four correspondingly distributed casters, and the top of the base plate is fixedly connected with two correspondingly distributed support sleeves. Support rods are movably inserted into the interior of each of the two support sleeves.

[0004] However, the aforementioned mathematical drawing board has some shortcomings in its use. The sponge cloth and the scraper board in the drawing board are fixedly connected by fixing bolts, which makes it inconvenient for teachers to replace them at any time. When replacing them, it is necessary to find a tool that can remove the bolts to complete the disassembly and assembly, which has certain limitations. Therefore, we propose a drawing tool.

A limiting rod 9 is fixedly connected between the two fixing plates 8, penetrating the cleaning plate 3 and slidably connected to the penetrating part. The cleaning plate 3 and the sliding groove 19 are connected by a moving mechanism. Two notches 4 are provided on the surface of the cleaning plate 3. A limiting insert 5 is slidably connected to the inner wall of the notches 4 and fixedly connected to the front end of the disassembly plate 15. A through groove 17 is provided in the middle of the disassembly plate 15, and a through groove 2 18 is provided in the middle of the cleaning plate 3. The disassembly plate 15 and the cleaning plate 3 are connected by a positioning mechanism.

[0030] Preferably, a movable base 12 is provided at the lower end of the panel body 10, and universal wheels are fixedly connected to the four corners of the lower end face of the movable base 12. The universal wheels facilitate the movement of the entire device.

[0031] Preferably, each of the casters has a braking function, and two support columns 11 are fixedly connected to the upper end of the movable seat 12. The upper end of the support column 11 is fixedly connected to the lower end of the panel body 10, and the lower end of the panel body 10 is provided with a controller that is fixedly connected to the surface of the corresponding support column 11.

[0032] Preferably, the moving mechanism includes a servo motor 1 fixedly connected to the left side of the top plate 2. The output end of the servo motor 1 is fixedly connected to a threaded rod 20 that penetrates the top plate 2 and is rotatably connected to the penetration part. The threaded rod 20 penetrates the dust removal plate 3 and is threadedly connected to the penetration part. The servo motor 1 can enable the threaded rod 20 to rotate in both directions.

[0033] Preferably, the positioning mechanism includes a pull plate 6 disposed at the front end of the dust removal plate 3, a pull handle 7 fixedly connected to the front end face of the pull plate 6, and two hollow cylinders 13 disposed at the rear end face of the pull plate 6, both of which are fixedly connected to the front end face of the dust removal plate 3.

[0034] Preferably, the inner walls of both hollow cylinders 13 are slidably connected to movable sliders 23. One side of the movable slider 23 is fixedly connected to a pull rod 21 that passes through the hollow cylinder 13 and is slidably connected to the through part. One end of the pull rod 21 is fixedly connected to the pull plate 6. A spring 22 is sleeved on the surface of the pull rod 21.

[0036] The specific working principle and usage method of this utility model are as follows:

[0037] This utility model provides a drawing tool. In use, the servo motor 1 rotates the threaded rod 20, causing the cleaning plate 3 to move left and right. This allows the cleaning sponge 16 to move left and right on the writing surface of the panel body 10, achieving automatic wiping. The stability of the cleaning plate 3 during movement is improved by the fixing plate 8 and the limiting rod 9. Subsequently, the handle 7 can be pulled directly with one hand, causing the pull plate 6 to move. The movement of the pull plate 6 moves the pull rod 21 and the positioning insert 14, separating the positioning insert 14 from the through groove 17 and releasing the disassembly plate 15. With the limit set, the other hand can pull the disassembly plate 15 to remove the disassembly plate 15 and the cleaning sponge 16. At this time, the movement of the pull rod 21 will drive the sliding block 23 to move inside the hollow cylinder 13, which will compress the spring 22. During installation, the disassembly plate 15 is slid into the back of the cleaning plate 3. Positioning can be achieved through the notch 4 and the limit insert 5. Then, by releasing the pull handle 7, the pull rod 21 will drive the pull plate 6 to reset under the action of the spring 22's reset force, thereby resetting the positioning insert 14 and allowing the positioning insert 14 to slide into the through groove 17, thus completing the limit installation of the cleaning plate 3 and the cleaning sponge 16, which is quite convenient.
