Description

Technical Field

[0001] The present invention relates to the technical field of fine arts drawing, in particular to a device for accurately drawing fine arts drawing lines. Background Art

[0002] The precision drawing device for art drawing lines is a tool that can help art creators draw lines accurately. Art drawing is an artistic activity that uses various tools and materials to create visual images using visual elements such as lines, colors, and shapes. As we all know, art is one of the art categories. It is an artistic activity that uses certain material materials, such as paints, paper, etc., to shape visible plane or three-dimensional visual images to reflect natural and social life and express artistic ideas and feelings. Fine arts and other art education-related majors aim to cultivate the comprehensive development of morality, intelligence, physical fitness, and beauty, cultivate students to master the basic theories of art more systematically, and be able to better adapt to the reform and development of art education. With the purpose of being competent for art education and teaching, it also takes into account the cultivation of practical and applied talents engaged in work related to art majors. After the industrial revolution in the 18th century, the scope of art has been expanding, including painting, sculpture, arts and crafts, architectural art, etc. In the East, it also involves calligraphy and seal carving art. In the process of painting teaching, teachers need to explain painting techniques to students frequently, which requires teachers to show students painting examples frequently, and sometimes teachers need to explain while drawing.

[0003] When drawing, it is often necessary to draw horizontal and vertical lines. Currently, teachers use a T-square to clamp the edge of the drawing board to draw. This is not only inconvenient to operate, but also prone to deviation, causing the drawn straight lines to be skewed, affecting the drawing quality. The existing device cannot adjust the angle of the drawing board as needed, which is inconvenient for drawing. Therefore, a new design was developed to address this situation.

The inner side of the longitudinal mechanism is slidably connected to the outer side of the transverse rod, and one side of the outside of the limiting mechanism is fixedly connected to one side of the outside of the composite frame. The contraction degree of the second electric push rod is limited by the limiting mechanism to avoid damage to components due to excessive clamping.

[0005] Preferably, a support frame is fixedly connected to one side of the square frame away from the silicone pad, and a first electric push rod is fixedly connected between opposite surfaces of the support frame.

Secondly, the spring structure increases the support for the components, so as to achieve a braking effect on the components, prevent the failure of the components from causing excessive squeezing of the drawing board, prevent the components from being damaged, and thus extend the service life of the components.

[0017] 4. The device for accurately drawing lines of art drawings is designed with a cleaning mechanism. Wind is generated by a fan to absorb graphite ash and rubber crumbs from the funnel plate in turn, so as to clean the surface of the paper. The funnel plate guides the flow of dust and concentrates the entry of debris. The debris enters the collection shell through the connecting pipe, and the friction force on the debris is increased by the friction plate, so as to improve the retention effect of the debris, thereby better storing the debris.

The dust on the inner wall of the pipe is reduced by scratching, and dust agglomeration is avoided, thereby affecting the ventilation effect of the equipment. In the process of friction, there is a vibration caused by the influence of agglomeration, so that the telescopic rod squeezes the spring coil, so as to achieve the effect of shock absorption and buffering, thereby reducing the amplitude of the component and improving the stability of the component.

The paddle board 2496 is contacted by wind force, and the contact area with the airflow is increased by the paddle board 2496, so as to keep the component rotating, thereby driving the scraper 2495 to rub the inner wall of the pipe, so as to achieve the effect of cleaning dust, and reduce the dust on the inner wall of the pipe by scratching, so as to avoid dust agglomeration, thereby affecting the ventilation effect of the equipment. In the process of friction, there is a vibration caused by the influence of agglomeration, so that the telescopic rod 2493 squeezes the spring coil 2494, so as to achieve the effect of shock absorption and buffering, thereby reducing the amplitude of the component and improving the stability of the component.

[0032] During use, the staff inserts the drawing board from one side of the composite frame 11, and then controls the composite frame 11 to be squeezed toward the side of the square frame 15 through the second electric push rod 14, so as to fix the drawing board and prevent shaking during the drawing process on the drawing board surface, thereby affecting the painting quality. During the squeezing process, a silicone pad 16 is provided, and the silicone pad 16 increases the friction on the surface of the drawing board, further improves the stability of the drawing board, and reduces the wear between the two, thereby extending the service life of the components. Secondly, in the process of moving the composite frame 11 toward the square frame 15, the limiting mechanism 19 is driven to operate at the same time, and the limiting mechanism 19 plays a role in braking the squeezing process, avoiding damage to the drawing board caused by excessive squeezing, thereby maintaining the normal operation of the equipment, and controlling the lifting and lowering of the support frame 12 through the first electric push rod 13, so as to achieve the effect of controlling the ups and downs angle of the drawing board, thereby satisfying the user's drawing angle and improving the user's experience. 11 is provided with a longitudinal mechanism 18 and a transverse mechanism 17 on the inner side. The transverse mechanism 17 provides the user with transverse branch line drawing to prevent the user from shaking in the process of drawing long lines, thereby affecting the drawing quality, thereby improving the aesthetics of the painting. Secondly, the longitudinal mechanism 18 improves the user's ability to draw long longitudinal lines in the process of longitudinal drawing. Secondly, the longitudinal mechanism 18 provides circular drawings of different diameters to meet different drawing needs. In the process of drawing, when an error occurs during drawing, erasing the lines with an eraser will produce eraser debris. Manual sweeping will cause the graphite debris of the picture lines to diffuse, thereby affecting the picture effect. Therefore, the internal cleaning mechanism 24 of the processing mechanism 2 absorbs and cleans the debris on the surface of the picture, thereby achieving the effect of cleaning the picture, while preserving the integrity of the picture, which is convenient for subsequent cleaning of internal debris. When the drawing is completed, the components can be moved to the corresponding sides to avoid affecting the painting.
