Description

Technical Field

[0001] The utility model relates to the technical field of teaching equipment, in particular to a Chinese teaching board for foreigners. Background Art

[0002] Teaching Chinese as a foreign language refers to teaching Chinese to foreigners, that is, teaching Chinese as a foreign language or second language. Since the founding of the People's Republic of China, especially since the reform and opening up, teaching Chinese as a foreign language has been developing rapidly. After 1978, it was established as an independent discipline. In terms of teaching theory, teaching system, teaching method research, textbook compilation, level test and teacher training, efforts have been made and achievements have been made to build a teaching Chinese as a foreign language system that conforms to China's cultural conditions and the characteristics of the Chinese language and writing. It is becoming a language teaching with significant international significance.

[0003] When using existing Chinese teaching boards for foreigners, magnetic buckles are generally used to fix Chinese teaching graphic papers on the teaching boards for teaching. The magnetic buckles are easily lost due to touching and falling off when adsorbed on the teaching boards, which affects the next use of graphic papers for teaching. In addition, the teaching content on the teaching boards is generally cleaned with a blackboard eraser. When there is too much written content, the cleaning progress is slow, which affects the writing of teaching content.

[0004] In view of this, we propose a Chinese teaching board for foreigners. Utility Model Content

[0028] The front surface of the first side panel 3 is provided with two grids 13 for writing Chinese characters, and the front surface of the second side panel 4 is provided with adsorption grooves 15 for magnetically adsorbing a plurality of letter blocks 14 .

[0029] The above working principle: when in use, the user can perform writing teaching operations through the teaching mainboard 1, and can take out the first side panel 3 and the second side panel 4 from the accommodating chamber 2, so as to expand the writing area and facilitate teaching writing. When teaching, the user can write Chinese characters in the field grid 13 on the first side panel 3, so as to teach students the basic configuration of Chinese characters and increase the effect of Chinese writing teaching. When teaching Chinese, the letter blocks 14 magnetically fixed in the adsorption groove 15 can be buckled out, and the letter blocks 14 can be arranged and combined and magnetically adsorbed on the second side panel 4 to teach students the pinyin composition of Chinese characters and the pronunciation of Chinese characters. At the same time, when teaching, the pull plate 12 can be pulled to make the two pull rods 11 drive the control panel 8 to move, and the teaching can be The upper end of the drawing is inserted into the clamping groove, and the pull plate 12 is released. The control board 8 can be close to the teaching main board 1 under the elastic force of multiple reset springs 10 to clamp and fix the teaching drawings, which is convenient for the user to use the drawings for teaching each time. After the teaching content is written on the teaching main board 1, the control cover 5 can be pulled downward, so that the control board 8 drives the cleaning pad 9 to wipe and clean the teaching main board 1. With the cooperation of the two sliding blocks 6 and the sliding groove 7, the control cover 5 can be guaranteed to move stably on the teaching main board 1. Under the elastic force of multiple reset springs 10, the contact effect of the cleaning pad 9 and the teaching main board 1 can be guaranteed, thereby increasing the cleaning effect of the teaching content, and can be quickly wiped and rewritten, which greatly saves classroom time and facilitates teachers to grasp the teaching rhythm and progress.

[0030] In order to facilitate the stability of the first side panel 3 and the second side panel 4 when they are stored and unfolded, positioning components for controlling the first side panel 3 and the second side panel 4 are respectively arranged on both sides of the lower end of the teaching main board 1, and the positioning components include a positioning rod 16, and the outer fixed sleeve of the positioning rod 16 is connected with a positioning ring 17, and the interior of the teaching main board 1 is symmetrically provided with movable grooves for the positioning rod 16 and the positioning ring 17 to move, and the outer movable sleeve of the positioning rod 16 is provided with a positioning spring 18, and the two ends of the positioning spring 18 are respectively fixedly connected to the lower surface of the positioning ring 17 and the inner wall of the movable groove, and the lower surfaces of the first side panel 3 and the second side panel 4 are symmetrically provided with the positioning ring 17 and the inner wall of the movable groove.
