Description

Technical Field

[0001] The utility model relates to a multifunctional Chinese teaching board for foreigners, belonging to the technical field of teaching boards. Background Art

[0002] As my country's international status continues to improve, Chinese is also becoming increasingly popular. A large number of foreign students come to learn Chinese. Due to the particularity of Chinese, they need to understand a large number of vocabulary to ensure that people can use it normally in daily communication. Teaching boards are needed in Chinese teaching. Teaching boards are tools used for writing and demonstration in the education industry. Usually, teaching boards are placed in classrooms or conference rooms, and the content is written with chalk or water-based pens to serve the purpose of explanation and demonstration.

[0003] A search of Chinese patent CN216019742U discloses a multifunctional Chinese teaching board for foreigners, comprising a bottom plate, a telescopic table leg is arranged at the top of the bottom plate, a table is arranged at one end of the telescopic table leg, a cross piece is fixedly connected to one side of the telescopic table leg, a connecting seat is arranged on the surface of the cross piece, a screw is arranged inside the connecting seat, a nut is meshed on the surface of the screw, a first bevel gear is fixedly connected to the top of the nut, a second bevel gear is meshed on one side of the first bevel gear, a rotating shaft is fixedly connected to the inside of the second bevel gear, and a fixing plate is arranged at one end of the rotating shaft; the multifunctional Chinese teaching board for foreigners can achieve the free lifting of the table by being provided with a rotating handle, a rotating shaft, a first bevel gear, a second bevel gear, a screw, a nut, a cross piece, a table and telescopic table legs, so that not only the teaching board can be adjusted, but also the height of the table can be adjusted to facilitate teaching by users.

[0004] Although the teaching board of the above-mentioned prior art can adjust the height, its size is always fixed. When there are many words to be written on the teaching board, it cannot be used well. If the size of the teaching board is set too large, the teaching board will take up more space when the daily writing volume is small. In addition, the direction of the teaching board of the above-mentioned prior art is always fixed, which is not convenient for students in different directions to watch.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a multifunctional Chinese teaching board for foreigners in order to solve the above problems. The size of the teaching board can be changed according to the amount of vocabulary to be written, and the direction of the teaching board can be conveniently changed to facilitate viewing by students in different directions.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a multifunctional Chinese teaching board for foreigners comprises a lifting table, a supporting base is installed on the top outer wall of the lifting table, threaded supporting rods are respectively installed on the two side walls of the supporting base, a U-shaped frame is rotatably connected to the threaded supporting rod, a supporting main shaft is rotatably connected to the U-shaped frame, a main teaching board is installed on one end of the supporting main shaft, a clamping bottom plate is respectively installed on one side wall of the main teaching board, a clamping block is slidably clamped on the clamping bottom plate, a supporting side plate is installed on one end of the clamping block, a side teaching board is installed on one side wall of the supporting side plate, a clamping rod is respectively installed on one side wall of the side teaching board, and the clamping rod is movably clamped with the main teaching board.

[0008] Furthermore, in order to limit the position of the side teaching board after the side teaching board is unfolded, a guide rod 1 is installed on the top outer wall of the main teaching board, an L-shaped limit plate is slidably clamped on the guide rod 1, and a limit block is installed on the top outer wall of the side teaching board.

[0009] Furthermore, in order to drive the L-shaped limiting plate to move downward, a supporting spring 1 is provided on the side wall of the guide rod 1.

[0010] Furthermore, in order to facilitate the adjustment of the angle of the main teaching board and to facilitate viewing by students in different directions, a clamping base is installed on the side wall of the supporting main shaft, a supporting vertical plate is installed on the top outer wall of the U-shaped frame, and two guide rods are respectively installed on one side wall of the supporting vertical plate, a guide plate is slidably clamped on the guide rod two, and a fixing rod is installed on one side wall of the guide plate, and the fixing rod is movably clamped with the clamping base.

[0011] Furthermore, in order to automatically drive the fixing rod to move, a second supporting spring is provided on the side wall of the second guide rod.

[0012] Furthermore, in order to fix the side teaching board when the side teaching board is rotated to the rear of the main teaching board, a push rod is installed on one side wall of the side teaching board, and a magnet sheet is installed on one side wall of the main teaching board.

[0013] Furthermore, in order to stably fix the teaching board after moving it to a designated location, movable wheels are respectively installed on the bottom outer wall of the lifting table, and fixed side panels are respectively installed on the two side walls of the lifting table. Guide columns are slidably clamped on the fixed side panels, a supporting base plate is installed at one end of the guide column, and an adjusting screw is connected to the fixed side panel.

[0014] Furthermore, in order to drive the supporting base plate to rise when the adjusting screw is loosened, a supporting spring three is provided on the side wall of the guide column.

[0015] The technical effects and advantages of the utility model are as follows: by rotating the side teaching board to unfold it and be parallel to the main teaching board, more content can be written on the teaching board. When in daily use, by pulling the L-shaped limit plate and then pulling the side teaching board outward, the clamping rod is disengaged from the positioning hole on the main teaching board, and then the side teaching board is rotated to the rear of the main teaching board, so that the teaching board is folded to avoid occupying space during daily use, so that the teaching board can be adjusted in size according to the amount of writing. When the students on the side of the teaching board cannot see the content on the teaching board clearly, by pulling the guide plate, the fixing rod is disengaged from the positioning hole on the clamping base, and then the main teaching board can be rotated to facilitate viewing by students in different directions.
