Description

Technical Field

[0001] The invention relates to the field of art auxiliary equipment, in particular to a brush calligraphy auxiliary practice copying table. Background Art

[0002] As a treasure of traditional Chinese culture and art, brush calligraphy has a profound historical background and unique artistic charm. In the process of calligraphy learning, copying is the key to mastering the brushwork, structure and style. However, the traditional calligraphy copying method has many inconveniences and limitations.

[0003] Traditional copying mainly relies on copybooks. Learners need to hold a brush and practice writing by comparing the characters on the paper copybook. The characters on the copybook are of fixed size. For learners with different vision and writing habits, it may be difficult to clearly observe the stroke details and overall structure, affecting the accuracy and effect of copying. Moreover, during the copying process, due to the lack of auxiliary positioning devices, the copying paper is prone to shifting and wrinkling, which interferes with the fluency of writing. Learners have to frequently adjust the position of the paper, which distracts their attention and reduces their learning efficiency.

[0004] With the development of technology, although some digital calligraphy learning tools have emerged, most of them only focus on the display of calligraphy works or simple stroke demonstration functions, and fail to effectively solve the practical operation problems in the copying process. For example, although some electronic calligraphy copybooks can display different fonts on the screen, they cannot provide the writing touch and texture similar to traditional writing paper, and there are still obvious deficiencies in paper processing, writing angle adjustment, and elimination of interference factors.

[0005] In addition, in calligraphy teaching scenarios, it is difficult for teachers to provide timely and accurate guidance for the individual problems that many students encounter when copying. For example, when students have poor copying results due to problems with the copybook display or uncomfortable writing posture, traditional teaching methods are difficult to quickly and effectively solve these problems, thus affecting the teaching progress and students' learning enthusiasm.

After the movement is completed, the second dial button 44 is rotated to make it stuck on the upper frame plate 4, and the second slide bar 42 is fixed. The criss-crossed first shading cloth 35 and second shading cloth 41 are used to make the writer only see a single character on the manuscript display screen 6, which can effectively reduce the bright light on the manuscript display screen 6 and the surrounding light. The first sliding bar 36 and the second sliding bar 42 are moved again, and the first coil spring 37 and the second coil spring 43 will automatically recycle the first shading cloth 35 and the second shading cloth 41 respectively. When the copying paper 10 is written, the DC motor 33 is started, and the DC motor 33 drives the worm gear reducer 32 to operate, driving the second pressing roller 8 to rotate stably. The friction between the second pressing roller 8 and the copying paper 10 is used to discharge the copying paper 10 from one side in an orderly manner, and the new copying paper 10 is laid tightly on the acrylic light-transmitting plate 5 again, which is convenient for copying and writing next time. At the same time, the dryer 31 is turned on during the discharge process, and the dryer 31 generates appropriate heat to heat the copying paper 10 written on the copying paper 1 0 is quickly dried to avoid damage to the copied font. When the height of the table 1 needs to be adjusted, by pressing the buttons 18 on both sides, the buttons 18 drive the support frame 17 and the pressure rods 19 on both sides to descend, thereby driving the U-shaped rod 21 at the bottom end of the support leg 20 to descend, so that the slider 27 on the U-shaped rod 21 moves smoothly in the inclined groove 26, driving the movable seat 24 inside the fixed seat 22 to shrink inward, so that the cylindrical pin 25 follows to shrink inward, so that the positioning hole 29 releases the limit of the cylindrical pin 25, and then the inner rod 12 can move freely up and down inside the outer rod 13 to adjust the height of the table 1. After the adjustment is completed, release the button 18, and the first spring 16 will make the support frame 17 rise and reset, thereby driving the bottom U-shaped rod 21 to follow and reset.By cleverly cooperating with the slider 27, the inclined slot 26 and the second spring 28, the cylindrical pin 25 is re-extended, and then the positioning hole 29 is used to accurately position the cylindrical pin 25, so as to achieve the fixed action after the desktop is raised or lowered, which is convenient for writers of different heights. At the same time, the electric cylinder 30 can also drive the internal piston rod to extend and retract, driving one end of the support plate 2 to rise, so that the support plate 2 can rotate a certain angle, so that the practitioner can adjust to the best viewing angle according to his own posture and writing habits.
