[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0032] Embodiment 1:

[0033] like Figure 1-3 As shown, an auxiliary chart drawing device includes a base 1 and a drawing board 2 arranged inside the base 1.

[0034] The outer wall of the drawing board 2 is provided with two auxiliary rulers 7, the auxiliary ruler 7 includes a ruler 1 8 and a ruler 2 9 slidably fitted at the bottom of the ruler 1 8, the two rulers 1 8 are rotatably connected through a rotating shaft 1 4, and a guide column 6 is fixedly connected to the bottom of one end of the ruler 2 9 away from the rotating shaft 1 4, and a guide groove 5 is opened on the inner wall of the drawing board 2, and the guide column 6 is movably limited and fitted in the guide groove 5.

[0035] When it is necessary to draw a straight line, one of the rulers 8 and the ruler 9 can be rotated with the axis of the rotating shaft 4 as the rotation center, and the guide column 6 slides along the path provided by the guide groove 5 to drive the ruler 9 to extend and retract. When the two rulers 8 are horizontal, a straight line can be drawn; when it is necessary to draw lines of other angles, the rulers 8 and the ruler 9 can be rotated to any angle.

[0036] The device is provided with two auxiliary rulers 7, and with the cooperation of the guide groove 5, the guide column 6, the ruler 1 8 and the ruler 2 9, the two auxiliary rulers 7 can be flexibly changed, so that the user can adjust the position and angle of the auxiliary ruler 7 according to his own needs, thereby improving the flexibility of the device.

[0037] like Figure 1 and Figure 4 As shown, a panel 13 is fixedly connected to the outer wall of the drawing board 2 , and a control board 11 and a plurality of LED lights 12 are arranged between the drawing board 2 and the panel 13 .

[0038] A plurality of buttons 3 corresponding to the number of the LED lights 12 are fixedly connected to the outer wall of one side of the base 1 , and the buttons 3 and the LED lights 12 are electrically connected to the control board 11 .

[0039] The buttons 3 and the control panel 11 can be used to control the on and off of the LED lights 12. Each button 3 corresponds to an LED light 12, and the user can turn on or off the LED lights 12 individually according to their own needs.

[0040] By setting up multiple LED lights 12, this device can provide the user with a uniform and soft light source, so that the image or text on the drawing board can be clearly displayed, improving the drawing quality, and setting up multiple buttons 3. The buttons 3 and the control panel 11 can be used to individually control the opening and closing of each LED light 12, thereby meeting the needs of different application scenarios.

[0041] Embodiment 2:

[0042] An auxiliary chart drawing device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 4-6 As shown:

[0043] The outer walls on both sides of the drawing board 2 are fixedly connected with a second rotating shaft 10, and the second rotating shaft 10 is rotatably connected to the inner wall of the base 1.

[0044] The outer walls on both sides of the drawing board 2 are provided with strip grooves 14, and the inner walls on both sides of the base 1 are rotatably connected with connecting rods 17 through rotating shafts 20, and the other end of the connecting rod 17 is movably limited and fitted in the strip grooves 14 through limiting columns 16.

[0045] An adjustment component is arranged on the outer side of one of the rotating shafts 3 20 , and the adjustment component includes a handle 15 and teeth 19 . The handle 15 is slidably fitted on the inner wall of one side of the base 1 , and the teeth 19 is fixedly connected to the outer wall of the rotating shaft 3 20 .

[0046] The inner wall of the handle 15 is provided with an avoidance groove 18 and a tooth groove for limiting the teeth 19 .

[0047] In this embodiment: when the angle of the drawing board 2 needs to be adjusted, the handle 15 is first pulled outward so that the tooth groove leaves the tooth 19 and the avoidance groove 18 reaches the tooth 19, but the avoidance groove 18 cannot limit the tooth 19, so that the rotating shaft 10 is no longer limited. At this time, the drawing board 2 can be rotated arbitrarily, and the cooperation of the strip groove 14, the limiting column 16 and the connecting rod 17 can provide support for the drawing board 2. After the angle adjustment is completed, the handle 15 is pressed inward so that the tooth groove limits the tooth 19 again. At this time, the drawing board 2 is also limited to maintain the current position unchanged.

[0048] The device can adjust the angle of the drawing board 2 by providing the strip groove 14, the limit column 16 and the connecting rod 17, and fix the angle of the drawing board 2 by using the adjustment component to avoid shaking, thereby improving the convenience and stability of the device.

[0049] Working principle: When the device is in use, paper is placed on the surface of the panel 13, and then the user can adjust the angle of the drawing board 2 according to his own needs, that is, first pull the handle 15 outward so that the tooth groove leaves the tooth 19, and the avoidance groove 18 reaches the tooth 19, but the avoidance groove 18 cannot limit the tooth 19, so that the rotation shaft 10 is no longer limited. At this time, the drawing board 2 can be rotated arbitrarily, and the cooperation of the strip groove 14, the limit column 16 and the connecting rod 17 can provide support for the drawing board 2. After confirming the angle, press the handle 15 inward so that the tooth groove limits the tooth 19 again. When the drawing board 2 is in the limited position, the drawing board 2 is also limited to keep the current position unchanged; when it is necessary to draw a chart, the light source can be adjusted as needed to provide a good drawing effect, that is, the corresponding LED light 12 is turned on and off using the button 3, so that the image or text on the drawing board can be clearly displayed, thereby improving the drawing quality; during drawing, when the auxiliary ruler 7 needs to be adjusted, the guide column 6 is moved along the guide groove 5, and the guide column 6 is used to drive the ruler 9 to extend and retract, thereby changing the position and angle of the auxiliary ruler 7, assisting in the drawing of horizontal lines, vertical lines and angles, etc., thereby improving the flexibility and freedom of drawing.

[0050] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
