A device for comparing and analyzing pictures that can be clipped and flipped based on the history of Chinese and foreign art

Abstract

The invention discloses a flip-flop comparison and analysis device for pictures based on Chinese and foreign art history, relates to the technical field of teaching devices, and solves the problems that the current picture comparison and analysis device does not fix the picture firmly, it is inconvenient to fix a long picture, and it is inconvenient to install a drawing board. It includes a base and a drawing board; two supporting frames are fixed and symmetrically connected by welding on both sides of the top of the base; two connecting rods are fixedly connected by welding between the two groups of rotating frames; A group of directional counterweight structures are fixedly arranged on one side; a total of four drawing board fixing grooves are fixedly arranged on the rear side of the drawing board; the drawing board is installed on the outside of the positioning knob through the drawing board fixing grooves. The main fixing rod of the device slides left and right to tighten the picture and is suitable for long pictures. Compared with the current device for fixing pictures by rubber bands, the convenience and firmness of the picture fixing by this device are greatly improved, and it is also It will not block long pictures.

Description

technical field [0001] The invention relates to the technical field of teaching devices, in particular to a device for comparing and analyzing pictures that can be clipped and flipped based on Chinese and foreign art history. Background technique [0002] The history of Chinese art has a long history. Unlike Europe, where art styles are always changing, Chinese art has maintained an amazing continuity over the centuries. The works of the Ming Dynasty can also see the influence of the Tang Dynasty. A painting from the Qing Dynasty is very similar to a painting from the Song Dynasty. One reason is China's reverence for tradition. The primary task of an artist is not to innovate, but to copy old works as realistically as possible-this is not considered plagiarism, but innovation to a certain extent. At present, many universities offer Chinese and foreign art history courses for their majors, and in teaching It is often necessary to compare different pictures between China a...

Problems solved by technology

[0005] The purpose of the present invention is to provide a picture comparison and analysis device based on Chinese and foreign art history, to solve the problem that the existing picture comparison and analysis device proposed in the above background technology mostly relies on the screen after shooting to compare and display pictures. However, there will be a slight color difference on the screen, and it is difficult to see the original picture effect. Some devices will fix the picture by tightening some rubber bands, but if there is a fan in the classroom, the rubber band is not fixed firmly, so Pictures are easy to be blown off by the fan, and it is inconvenient to fix long pictures, and it is easy to block the middle position of the picture. At the same time, these analysis devices need to be fixed with a special fastening connection structure when the drawing board is used for teaching, and it is not convenient to install the drawing board.
