Description

Technical Field

[0001] The utility model belongs to the technical field of graphics drawing auxiliary equipment, in particular to a multifunctional geometric graphics drawing tool. Background Art

[0002] As is known to all, when conducting mathematical research and engineering surveying and mapping, it is necessary to use drawing tools for measurement and drawing, which is convenient for recording and observation. Existing multifunctional drawing tools generally associate a compass and a ruler for drawing, so as to reduce the problem of frequent replacement of drawing tools when surveying and mapping figures. However, since the compass cannot control the angle between the compass fulcrum and the moving point when drawing an arc line, it is necessary to use a semicircular ruler to adjust the angle, and then draw the arc line at a fixed point, which requires the use of multiple tools during the drawing process, and frequent replacement of drawing tools, which reduces the efficiency of drawing.

[0003] After searching, for example, (CN211106602U) a multifunctional drawing teaching aid, the teaching aid includes a main ruler A and a main ruler B, the main ruler B is placed on the main ruler A, the main ruler A is movably connected to the main ruler B through a locking member, the main ruler A and the main ruler B are both provided with scales along the length direction, and the main ruler A is provided with angle scales. The device solves the problem that the radius size cannot be quantitatively adjusted when the existing equipment is used and the center of the circle is unstable when drawing arc lines. However, when the device makes quantitative adjustments to the angle, it is necessary to use a semicircular ruler to adjust the angle between the fixed end and the movable end of the compass, and it is necessary to frequently replace the surveying and mapping tools in this process, which reduces the drawing efficiency of the device.

[0029] like Figures 1 to 6 As shown, the present embodiment comprises a fixed plate 1 for multifunctional collective drawing and a movable plate 7 for arc linear drawing when drawing, and a gear for adjusting the rotation angle is provided at the connection between the fixed plate 1 and the movable plate 7, and the outer wall of the gear is not completely provided with tooth grooves, so that the movable plate 7 and the fixed plate 1 have certain adjustment restrictions when rotating, and a large friction resistance is provided at the gear connection between the fixed plate 1 and the movable plate 7, and the setting of the friction resistance can facilitate the stability of the angle between the movable plate 7 and the fixed plate 1 when adjusting the two.

[0030] The fixed plate 1 is rotatably connected with the movable plate 7. A long plate 2 for easy use is provided on one side of the fixed plate 1. A handle is provided on the side wall of the long plate 2 for easy application when pulling. The long plate 2 can be separated from the fixed plate 1 by the provided handle. Limiting columns 13 for auxiliary fixing are symmetrically connected on both sides of the long plate 2. The limiting columns 13 are connected with limiting holes at the ends of the slide grooves provided inside the fixed plate 1. Then, under the action of the limiting columns 13 and the limiting holes, the connection between the long plate 2 and the fixed plate 1 is completed.

[0031] A circular ruler 12 is provided in the middle of the long board 2 for adjusting angle measurement during geometric drawing. The circular ruler 12 is slidably connected to a slide groove for convenient placement of objects. The end of the slide groove is provided with a limiting hole corresponding to the limiting column 13. The limiting hole cooperates with the sliding connection of the limiting column 13, so that after the long board 2 is connected to the inner wall of the slide groove, the long board 2 can be fixed with the assistance of atmospheric pressure.

[0032] The side wall of the fixed plate 1 is provided with a drawer box 3 for easy pulling out. The drawer box 3 is located on one side of the long plate 2. A conical connecting head 10 for easy connection is provided in the drawer box 3. The connecting head 10 is connected to the threaded hole 8 provided at the end of the movable plate 7. The drawer box 3 is slidably connected to the connecting groove provided inside the fixed plate 1, and then under the action of the handle provided at the end of the drawer box 3, the drawer box 3 is pulled out, and a lower locking buckle for easy fixation is provided at the end of the drawer box 3. The lower locking buckle is engaged with the upper locking buckle provided on the side wall of the fixed plate to complete the fixation of the drawer box 3 and the fixed plate 1. When the device is used to draw geometric figures, the connection between the conical connecting head 10 and the fixed plate 1 is completed, which is convenient for use.

[0033] A fixing groove for easy connection is provided at the top of the movable plate 7, and the inner wall of the fixing groove is movably connected to the ruler 6. In order to facilitate the use of the ruler 6, a scale for measuring and counting is engraved on the surface of the ruler 6. A symmetrical connecting plate 14 is provided on one side of the ruler 6, and a card slot for easy fixation is provided on the top of the connecting plate 14. A plug plate 15 for easy connection is provided on the side of the ruler 6 away from the connecting plate 14. The connecting plate 14 passes through the connecting groove provided inside the movable plate 7, and the plug plate 15 is connected to the slot provided inside the movable plate 7, and is connected to the card block 16 provided, and then under the action of the card block 16, the connection between the ruler 6 and the movable plate 7 is completed.

[0034] A pressing cap 5 is provided at the end of the movable plate 7 and is slidably connected to the movable plate 7. The pressing cap 5 is connected to one end of a connecting rod 18. The side wall of the connecting rod 18 is slidably connected to a connecting groove arranged inside the movable plate 7, and a square plate 17 is welded to the other end of the connecting rod 18. A spring with a damper is provided between the square plate 17 and the connecting groove. The connecting rod 18 connected is driven by the pressing cap 5 to move inside the connecting groove, and the pressing spring contracts to complete the separation of the block 16 and the groove arranged on the top of the connecting plate 14, thereby separating the ruler 6 from the movable plate 7 for easy use.

[0035] When drawing geometric figures, the device can not only draw straight lines, but also drive the conical connector 10 to rotate on the drawing by rotating the round rod 4 with vertical lines, and complete angle adjustment in conjunction with the circular ruler 12. It is flexible and can avoid the problem of frequent tool changes when drawing geometric figures, and is easy to operate.

[0036] How it works

[0037] When the operator uses the multifunctional geometric figure drawing tool to draw geometric figures, first, the straight line drawing of the figure is completed by the ruler 6. If it is necessary to draw an arc line, the drawer box 3 can be separated from the fixed plate 1 by the lower lock buckle, and the conical connecting head 10 can be taken out, and connected to the threaded hole 8 set at one end of the fixed plate 1 by the threaded column, and then the long plate 2 can be taken out by the handle. Because a circular ruler 12 for angle measurement is provided on one side of the long plate 2, the angle between the movable plate 7 and the fixed plate 1 can be adjusted to complete the drawing of the arc line, thereby reducing the problem of frequent tool replacement when drawing geometric figures.
