The history of drawing devices for mathematical modeling can be traced back to the early days of manual drawing. Mathematicians usually use paper and pen to draw graphics to help them understand and analyze mathematical models. Over time, drawing tools and techniques have continued to develop, and various physical drawing devices for mathematical modeling have emerged, such as tripods, drawing boards, coordinate axes, etc. Mathematical modeling can be applied to various fields, such as physics, engineering, economics, medicine, etc.

[0004] In the prior art, the drawing device structure used for mathematical modeling usually includes a drawing tablet, drawing tools, coordinate axes, etc. During the mathematical modeling drawing process, the same mathematical model has multiple solutions, so there are multiple drawing directions.

[0016] A method for using a drawing device for mathematical modeling comprises the following steps:

[0017] S1. First, put the adjustment slot on the outside of the slider and put the drawing frame on the two supporting legs. At this time, the angle of the drawing frame can be adjusted so that the drawing frame is at an angle suitable for mathematical modeling personnel. After the adjustment is completed, the card block is inserted into the inside of the positioning slot under the rebound action of the connecting spring. At this time, the card block can be prevented from shaking up and down under the connection of the connecting spring by the limiting telescopic plate. At the same time, the strengthening diagonal rod and the supporting legs cooperate with each other to complete the support of the device;

[0018] S2. After the drawing components are installed, the drawing paper is spread flat on the surface of the drawing pad. The electrostatic sticker uses its own electrostatic adsorption force to help the paper adsorb on its surface. By rotating the clamping plate, the magnetic plate and the magnetic block are magnetically adsorbed, which can tightly clamp the two sides of the drawing paper, thereby completing the positioning of the drawing paper. At this time, basic patterns, such as the coordinate system, can be drawn on the surface of the drawing paper.

[0019] S3. Pull the iron handle to pull the transparent drawing board outward until it is attracted by the magnetic strip. When erasing the content drawn on the surface of the transparent drawing board, the reinforcing plate is toggled to slide between the inner limit rod and the outer limit rod, so that the eraser can erase the content drawn on the surface of the transparent drawing board. At this time, the drawing paper is located behind the transparent drawing board. The controller controls the multi-stage electric push rod to start, so as to adjust the position of the drawing pad, and then adjust the spatial distance relationship between the basic pattern and the new drawing content according to the drawing requirements during mathematical modeling. When no adjustment is needed, the multi-stage electric push rod is started to extend it, so that the drawing pad is fitted with the drawing frame, that is, the drawing paper can be fitted with the transparent drawing board.

[0020] S4. After each drawing is completed, the controller is used to start the camera to shoot the modeled drawings, thereby realizing the storage of the drawings. In addition, during the shooting process, the controller is used to start the electric telescopic rod, which can drive the electric telescopic rod to adjust the position of the movable rod, thereby adjusting the position of the camera.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. When in use, the electrostatic adsorption force of the electrostatic sticker can help the paper to be adsorbed on its surface. The magnetic adsorption between the magnetic plate and the magnetic block can enable the clamping plate to tightly clamp the two sides of the drawing paper, thereby completing the positioning of the drawing paper. After drawing the basic pattern, the transparent drawing board is pulled outward by pulling the iron handle. The transparent drawing board is initially rolled up. When the transparent drawing board is pulled out, the winding spring is also in a completely unfolded state. The two sets of anti-slip shafts move between the corresponding inner positioning plate and the outer positioning plate, thereby achieving the benefit of keeping the transparent drawing board tight when stretched, making it easier to draw. There is no need to repeatedly draw the same basic pattern. By turning the reinforcement plate, the eraser can erase the content drawn on the surface of the transparent drawing board.

[0023] 2. When in use, the controller controls the multi-stage electric push rod to start, so as to adjust the position of the drawing pad, and then adjust the spatial distance relationship between the basic drawing and the new drawing content according to the drawing requirements during mathematical modeling. When no adjustment is needed, the multi-stage electric push rod is started to extend, and the drawing pad is fitted with the drawing frame, that is, the drawing paper can be fitted with the transparent drawing board. After each drawing is completed, the camera is started to take a picture of the modeled drawing, thereby realizing the storage of the drawing. In addition, during the shooting process, the controller controls the electric telescopic rod to start, so that the electric telescopic rod can drive the position of the adjustment rod, thereby adjusting the position of the camera, so that the captured picture is more complete.

[0024] 3. When in use, each support block is installed on the outer surface of the drawing frame by using screws to complete the installation of the fixed shell, and then the adjustment slot is put on the outside of the slider, and the drawing frame is mounted on the two support legs. The drawing frame can be rotated to adjust the angle of the drawing frame so that the drawing frame is at an angle suitable for mathematical modeling personnel. After the adjustment is completed, under the rebound action of the connecting spring, the card block can be driven to be inserted into the interior of the positioning slot. After the adjustment is completed, the support legs play the role of supporting the entire device. The support of the support legs is supported by the strengthening diagonal rods, so that a stable triangular structure is formed between the support legs, the strengthening diagonal rods and the fixed base plate, which can effectively prevent the collapse of the device. In addition, the anti-slip pad is a hard rubber pad, which can prevent the device from sliding by itself during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] As shown in Figure 1-3, an electric telescopic rod 407 is set near the top of the front surface of the drawing frame 101, and a mounting block 405 is fixedly installed on one end of the electric telescopic rod 407. A movable rod 403 is fixedly connected to the front surface of the mounting block 405, and an auxiliary plate 402 is fixedly connected to one end of the movable rod 403. A camera 401 is set on one side of the auxiliary plate 402. The camera 401 is started by the controller 13 to shoot the modeled drawings, thereby realizing the storage of the drawings. In addition, during the shooting process, the electric telescopic rod 407 is started by the controller 13, so that the electric telescopic rod 407 can drive the position of the movable rod 403 to be adjusted, thereby adjusting the position of the camera 401 to make the shot more complete.

[0045] As shown in Figures 1-3 and 6, a controller 13 is provided on one side of the drawing frame 101, and adjustment components 5 are fixedly installed on both sides of the drawing frame 101. The two adjustment components 5 include a fixed shell 501, and the interiors of the two fixed shells 501 are provided with adjustment slots 503. The opposite inner walls of the two adjustment slots 503 are provided with movable slots 502. The outer surfaces of the two fixed shells 501 are provided with positioning slots 504. The top and bottom of the two fixed shells 501 are fixedly connected with support blocks 505. The drawing frame 101 is placed downward so that the slider 506 reaches the top of the adjustment slot 503.

When the drawing frame 101 is adjusting its angle, the support leg 511 can move inside the movable slot 502, and the movable slot 502 can prevent the fixed shell 501 from blocking the support leg 511.

[0046] As shown in Figures 1-3 and 6, the interiors of the two adjustment slots 503 are slidably connected with sliders 506, the outer surfaces of the two sliders 506 are fixedly connected to the limiting blocks 507, the outer surfaces of the two limiting blocks 507 are provided with connecting springs 509, one end of the two connecting springs 509 is fixedly connected to a clamping block 510, the two clamping blocks 510 are respectively engaged with the inner walls of the two positioning slots 504, the inner wall of each clamping block 510 is respectively fixedly connected to the outer surface of each limiting block 507 with a limiting telescopic plate 508, the bottoms of the two sliders 506 are fixedly connected to support legs 511, the bottom ends of the two support legs 511 are welded with fixed base plates 7, the bottoms of the two fixed base plates 7 are fixedly installed with multiple anti-slip pads 8, the outer surfaces of both sides of the two support legs 511 are respectively welded to the tops of the two fixed base plates 7 It is connected to a reinforcing diagonal rod 6, and under the rebound action of the connecting spring 509, it can drive the card block 510 to be inserted into the interior of the positioning groove 504. During the insertion process, the angle of the drawing frame 101 can be fine-tuned so that the card block 510 and the positioning groove 504 are engaged. At this time, the limiting position of the telescopic plate 508 can prevent the card block 510 from shaking up and down under the connection of the connecting spring 509, thereby increasing the stability of the card block 510. Then, the support leg 511 after the adjustment plays the role of supporting the entire device, and then the support leg 511 is supported by the reinforcing diagonal rod 6, so that a stable triangular structure is formed between the support leg 511, the reinforcing diagonal rod 6 and the fixed base plate 7, which can effectively prevent the device from collapsing. In addition, the anti-slip pad 8 is a hard rubber pad, which can prevent the device from sliding by itself during use.

[0047] In the present invention, first, each support block 505 is installed on the outer surface of the drawing frame 101 by using screws, thereby completing the installation of the fixed shell 501, and then the adjustment slot 503 is sleeved on the outside of the slider 506, and the drawing frame 101 is placed on the two support legs 511. When the slider 506 has not yet reached the top of the adjustment slot 503, the drawing frame 101 begins to rotate. At this time, the angle of the drawing frame 101 can be adjusted so that the drawing frame 101 is at an angle suitable for mathematical modeling personnel. After the adjustment is completed, the drawing frame 101 is placed downward so that the slider 506 reaches the top of the adjustment slot 503. At this time, the position of the block 510 matches the position of the positioning slot 504. Under the rebound action of the connecting spring 509, it can The clamping block 510 can be driven to be inserted into the interior of the positioning groove 504. During the insertion process, the angle of the drawing frame 101 can be fine-tuned so that the clamping block 510 and the positioning groove 504 are engaged. At this time, the clamping block 510 can be prevented from shaking up and down under the connection of the connecting spring 509 by the limiting telescopic plate 508, thereby increasing the stability of the clamping block 510. Then, the support leg 511 after the adjustment plays the role of supporting the entire device, and the support leg 511 is supported by the strengthening diagonal rod 6, so that a stable triangular structure is formed between the support leg 511, the strengthening diagonal rod 6 and the fixed bottom plate 7, which can effectively prevent the device from collapsing. In addition, the anti-slip pad 8 is a hard rubber pad, which can prevent the device from sliding on its own during use. After the drawing component 1 is installed After the drawing is completed, the drawing paper 306 is spread on the surface of the drawing pad 301. The electrostatic sticker 305 adsorbs the paper on its surface through its own electrostatic adsorption force, which plays an auxiliary role when placing the drawing paper 306 on the surface of the drawing pad 301. At this time, the two side edges of the drawing paper 306 are respectively located outside the two magnetic plates 302. By rotating the clamping plate 308, the clamping plate 308 rotates around the fixed rod 309. There is magnetic adsorption between the magnetic plate 302 and the magnetic block 303, which can tightly clamp the two sides of the drawing paper 306, thereby completing the positioning of the drawing paper 306. At this time, a basic pattern, such as a coordinate system, can be drawn on the surface of the drawing paper 306. After drawing the basic pattern, the iron handle 110 is pulled to drive When the transparent drawing board 102 is pulled outward, the coil spring 106 is rolled up when there is no external force, and one side of the coil spring 106 is fixed to the rotating rod 104, and the other side is fixed to the positioning rod 107. Therefore, the transparent drawing board 102 is rolled up in the initial state, and the stopper 108 can prevent the coil spring 106 from popping outward and causing deformation. When the transparent drawing board 102 is completely pulled out, the coil spring 106 is also in a completely unfolded state. The two sets of anti-slip shafts 105 move between the corresponding inner positioning plates 111 and outer positioning plates 112, thereby limiting the movable path of the transparent drawing board 102, achieving the state of stretching the transparent drawing board 102 to make it taut, which is convenient for drawing. When drawing on the surface of the transparent drawing board 102, an erasable pen needs to be used.The erasable pen can be any commonly used type on the market. There is no need to repeatedly draw the same basic pattern. By toggling the reinforcement plate 11, the reinforcement plate 11 slides between the limit inner rod 10 and the limit outer rod 9, so that the eraser 12 erases the content drawn on the surface of the transparent drawing board 102. At this time, the drawing paper 306 is located behind the transparent drawing board 102. The controller 13 controls the activation of the multi-stage electric push rod 204, so that the multi-stage electric push rod 204 drives the drawing pad 301 to move outside the support rod 201, thereby being able to adjust the position of the drawing pad 301, and then being able to adjust the basic pattern and the newly drawn content according to the drawing requirements during mathematical modeling. When the spatial distance between the containers does not need to be adjusted, the multi-stage electric push rod 204 is activated to extend it, and the drawing pad 301 is completely attached to the drawing frame 101, that is, the drawing paper 306 can be completely attached to the transparent drawing board 102. After each drawing is completed, the controller 13 is controlled to start the camera 401 to take a picture of the modeled drawing, thereby realizing the storage of the drawing.
