DETAILED DESCRIPTION

[0029] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0030] like Figure 1-Figure 5 As shown, this embodiment provides a multifunctional art ruler, including a ruler body 1, and an extension ruler 3 that can slide and / or rotate around the ruler body 1. The extension ruler 3 can rotate or slide around the ruler body 1, so as to extend the length of the ruler body 1 and measure the angle at the same time. Both the ruler body 1 and the extension ruler 3 are provided with scales.

[0031] It also includes a pull rope 10 with adjustable length, the two ends of which are respectively connected to the extension ruler 3 and the ruler body 1. Through the set pull rope 10, when drawing an ellipse, the brush only needs to abut against the pull rope 10, and the ellipse can be drawn by limiting the position of the brush through the pull rope 10.

[0032] The extension ruler 3 is provided with a perfect circular hole 14 for a paintbrush to pass through. The end of the extension ruler 3 away from the ruler body 1 is fixedly connected to a swivel 9, one end of a pull rope 10 is connected to the swivel 9, and the perfect circular hole 14 is provided on the swivel 9, and a paintbrush can be inserted into the perfect circular hole 14.

[0033] According to the radius of the required perfect circle, adjust the appropriate length of the extension ruler 3 and the ruler body 1. By pressing the appropriate position of the ruler body 1 and rotating the ruler body 1 and the extension ruler 3, the brush can be driven to rotate to achieve the drawing of a perfect circle, and perfect circles of different radii can be drawn.

[0034] The ruler body 1 is provided with a slide groove 2, and the extension ruler 3 is movably arranged in the slide groove 2. The slide groove 2 is slidably connected to the slide 15, and the friction between the slide 15 and the slide groove 2 is sufficiently appropriate. The extension ruler 3 is movably mounted on the slide 15, and the extension ruler 3 can slide or rotate around the slide 15, thereby adjusting the angle between the extension ruler 3 and the ruler body 1. The slide 15 can only slide along the length direction of the slide groove 2. The upper surface of the slide groove 2 is flush with the upper surface of the ruler body 1. By moving the slide 15, the extension ruler 3 can be moved out of the ruler body 1 to an appropriate length.

[0035] The extension ruler 3 is fixedly connected to the angle disk 4, and the ruler body 1 is fixedly connected to the indicator mark 8 located on one side of the angle disk 4. When the indicator mark 8 is flush with the horizontal center line of the angle disk 4, the upper surface of the extension ruler 3 is flush with the upper surface of the ruler body 1. There is an angle scale on the angle disk 4. When the extension ruler 3 is rotated, the angle between the extension ruler 3 and the ruler body 1 at this time can be obtained according to the angle scale corresponding to the indicator mark 8 at this time, so that the angle can be measured or drawn.

[0036] The slide 15 is threadedly connected with a bolt 6. When the bolt 6 is screwed in toward the slide 15, it abuts against the angle disk 4, thereby locking the rotation of the extension ruler 3. At this time, the extension ruler 3 cannot rotate. When the bolt 6 is screwed out toward the direction away from the slide 15, a gap is formed between the bolt 6 and the angle disk 4, and the extension ruler 3 can rotate around the slide 15.

[0037] The ruler body 1 is rotatably connected to a rotating cylinder 12, and the other end of the pull rope 10 is wrapped around the rotating cylinder 12. The rotating cylinder 12 is provided with a plurality of slots 19. The ruler body 1 is slidably connected to an insertion rod 20 that can slide into the slots 19. By rotating the rotating cylinder 12, the length of the pull rope 10 can be adjusted to draw different ellipses.

[0038] The ruler body 1 is slidably connected to the pressure rod 11, and the pressure rod 11 is connected to the ruler body 1 through a spring 22. The ruler body 1 is rotatably connected to the gear 21. The pressure rod 11 and the insertion rod 20 are respectively provided with racks on one side close to the gear 21. The two sides of the gear 21 are respectively engaged with the racks provided on the pressure rod 11 and the insertion rod 20. The spring 22 is sleeved on the pressure rod 11, one end of the spring 22 is connected to the ruler body 1, and the other end of the spring 22 is connected to the pressure rod 11. Under the elastic force of the spring 22, the insertion rod 20 can slide into the slot 19 to limit the rotating cylinder 12.

[0039] The ruler body 1 is provided with a graphic frame 16, and a slide plate 17 is slidably connected to the graphic frame 16. The two sides of the slide plate 17 cooperate with the graphic frame 16 to form a parallelogram frame groove and a quadrilateral frame groove respectively. By moving the slide plate 17, quadrilaterals and parallelograms of different sizes can be drawn, which is beneficial to the progress of art drawing work.

[0040] The ruler body 1 is provided with a curve groove 18, which can realize the drawing of curves.

[0041] The two ends of the ruler body 1 are slidably connected to the scale, and the scale is rotatably connected to the rotating ruler 5. By pulling the rotating ruler 5, the scale can be moved to a sufficient length. By rotating the rotating ruler 5, the angle between the rotating ruler 5 and the scale can be adjusted. According to the size of the angle, regular polygons can be drawn.

[0042] The specific working process is as follows: when drawing an ellipse, the distance between the two ends of the pull rope 10 can be adjusted by pulling the extension ruler to determine the two foci of the ellipse. By pressing the pressure rod 11, the pressure rod 11 drives the insertion rod 20 to move out of the slot 19 through the gear 21. At this time, the rotating cylinder 12 can be rotated to adjust the length of the pull rope 10. Then, the pressure rod 11 is released, and the spring 22 drives the pressure rod 11 to reset. The pressure rod 11 drives the insertion rod 20 to slide into the slot 19 to limit the rotating cylinder 12, thereby realizing the adjustment of the ellipse.

[0043] Unscrew the bolt 6 in the direction away from the slide 15. At this time, a gap is formed between the bolt 6 and the angle disk 4, and the extension ruler 3 can rotate around the slide 15. According to the angular scale corresponding to the indicator mark 8 at this time, adjust the extension ruler 3 to a suitable angle. Then, screw the bolt 6 in the direction close to the slide 15. The bolt 6 abuts against the angle disk 4, and the rotation of the extension ruler 3 is locked. At this time, the extension ruler 3 cannot rotate, and the angle can be measured or drawn.

[0044] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
