Description

Technical Field

[0001] The present invention relates to the technical field of teaching equipment, and particularly relates to a Chinese teaching demonstration board. Background Art

[0002] In today's Chinese teaching activities, the effectiveness of teaching tools has a crucial impact on teaching quality; as an indispensable tool in Chinese teaching, the performance and functions of the demonstration board are directly related to the smoothness of the teaching process, the learning effect of students, and the achievement of teachers' teaching goals.

[0003] Traditional demonstration boards have limited space and are mostly for single-sided use only; in actual teaching, the limited single-sided space often cannot accommodate such rich teaching content at the same time, and teachers often need to frequently erase the written content to make room for new content, which not only interrupts the teaching rhythm but also may make it difficult for students to establish a complete knowledge framework and affect the learning effect; although some demonstration boards are equipped with display screens, their combination with the demonstration board is relatively simple and fails to fully utilize the advantages of their collaborative display, making it difficult to meet these complex and changeable display requirements in the same space and at the same time; in addition, although some demonstration boards are equipped with display screens, after long-term use, a large amount of dust is likely to accumulate on the surface of the display screen, affecting the display effect and reducing the viewing experience of students. Moreover, once dust and moisture enter the interior of the display screen, it may cause damage to electronic components, shorten the service life of the display screen, increase the maintenance cost of teaching equipment, and seriously affect the normal progress of teaching, disrupt the teaching plan, and bring many inconveniences to teachers and students. Summary of the Invention

[0004] The purpose of the present invention is to provide a Chinese teaching demonstration board to solve the technical problems existing in the prior art.

Detailed implementation manners

[0028] In order to make the content of the present invention be more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0029] As Figure 1-2As shown in the figure, in this embodiment, a Chinese teaching demonstration board is provided, including: a base 1, a receiving component 2 arranged at the top end of the base 1, a demonstration board body 3 movably connected to one end of the receiving component 2, and a display screen 7 embedded in the working surface on one side of the demonstration board body 3; the base 1 has a preset bearing capacity, and universal wheels 10 are provided at the four corners of its bottom. The setting of the universal wheels 10 enables the teacher to flexibly move the demonstration board to the best teaching position according to the actual situation such as the placement of desks and chairs and the position of doors and windows in the classroom; on the working surface of the top of the base 1, electric elevators 12 are symmetrically arranged. The electric elevators 12 are prior art and will not be elaborated here; the telescopic end of the electric elevator 12 is magnetically connected to the demonstration board body 3 through a magnetic attraction member 4. The setting of the magnetic attraction member 4 can make the rotation of the demonstration board body 3 more flexible. The teacher can quickly separate the demonstration board body 3 and reconnect it to a suitable position to meet different teaching scenarios and improve the convenience of teaching; and it can resolve the external force generated by accidental collisions or slight vibrations during the teaching process, enabling the teaching activities to proceed normally without interference; the receiving component 2 is located on the opposite side of the electric elevator 12 and is connected to the electric elevator 12 through a transmission rod 8. When adjusting the height of the demonstration board body 3, the receiving component 2 moves along with the movement trend of the electric elevator 12 through the transmission rod 8; on the working surface of the side of the demonstration board body 3 away from the display screen 7, an erasing component 5 is provided. The setting of the erasing component 5 enables the teacher to quickly clean the demonstration board body 3, greatly saving time, and thus maintaining the compactness of the teaching rhythm; on the working surface of one side of the display screen 7, a dust-proof component 6 is provided. The dust-proof component 6 can prevent dust and moisture from entering the inside of the display screen 7 and causing damage to electronic components, extend the service life of the display screen 7, and thus reduce the teaching cost.

[0030] As Figure 3 shown, the receiving component 2 includes: a base 201 and a telescopic rod 202 slidably connected to the base 201; the base 201 is fixedly connected to the base 1; the telescopic rod 202 has a preset damping, and the top end is rotatably connected to the middle position of the bottom end of the demonstration board body 3 through a rotating shaft 9, and both of its working surfaces are connected to the electric elevator 12 through the transmission rod 8; during operation, when the teacher adjusts the height of the demonstration board body 3, the electric elevators 12 on both sides drive the telescopic rod 202 to move synchronously through the transmission rod 8, so as to adjust the height of the demonstration board body 3; when the demonstration board body 3 needs to be rotated, the teacher pushes one side of the demonstration board body 3. At this time, the magnetic attraction member 4 separates, and the demonstration board body 3 rotates along the circumferential direction of the rotating shaft 9 until the flipping is completed. After the flipping is over, the magnetic attraction member 4 is magnetically connected again to fix the demonstration board body 3.

[0031] As Figure 9As shown, the magnetic attraction member 4 includes: a mounting base 401 and second magnets 403 symmetrically arranged at the bottom end of the teaching board body 3. A first magnet 402 is provided at the top end of the mounting base 401. The first magnet 402 is magnetically connected to the second magnets 403. The magnetic poles of the contacting surfaces of the first magnet 402 and the second magnets 403 are opposite, which can better fix the teaching board body 3 and the electric elevator 12.

[0032] As Figure 5 shown, the erasing member 5 includes: a slideway 501 and an eraser 502 slidably connected to the slideway 501. The slideway 501 is in a U shape and is symmetrically arranged at both ends of the teaching board body 3 and is slidably connected to the eraser 502 through a slider. A handle 503 is provided on one working surface of the eraser 502, and eraser storage boxes 504 are provided on both sides of the handle 503. When cleaning the teaching board body 3, the teacher pulls the handle 503 to drive the eraser 502 to slide along the preset track of the slideway 501. During this process, the eraser 502 clears the writing on the teaching board body 3 on a large area. If the teacher wipes a small area, he can take out the small eraser placed in the eraser storage box 504 to clean the area to be wiped.

[0033] As Figure 4 and 7 shown, the dust-proof member 6 includes: a reel 601. The reel 601 is arranged on one working surface of the teaching board body 3 and a rolling curtain 602 is wound inside. The rolling curtain 602 has a preset toughness, and a limiting member 11 is provided at one end away from the reel 601. The limiting member 11 is used to fix the rolling curtain 602. When the display screen 7 is not needed, the teacher pulls the rolling curtain 602 to cover the display screen 7 and inserts the rolling curtain 602 into the limiting member 11 for fixation, which can effectively prevent dust and water vapor from entering the inside of the display screen 7.

[0034] As Figures 6-8As shown in the figure, the limit component 11 includes: a plug-in box 1103 and a connecting piece 1101 that can be plugged into the plug-in box 1103; one working surface of the connecting piece 1101 is connected to one end of the rolling curtain 602, and a first inclined plate 1102 is provided on the other working surface; the plug-in box 1103 is located on the teaching board body 3, and a connecting rod 1104 is provided through one working surface thereof. A second inclined plate 1106 is provided at the bottom end of the connecting rod 1104, and a return spring 1105 is sleeved outside it; during operation, the first inclined plate 1102 abuts against the second inclined plate 1106, and the working dimensions of the first inclined plate 1102 and the second inclined plate 1106 are adapted. Specifically, when the connecting piece 1101 drives the first inclined plate 1102 to insert into the plug-in box 1103, the inclined surface of the first inclined plate 1102 is in sliding contact with the inclined surface of the second inclined plate 1106. At this time, the second inclined plate 1106 jacks up the connecting rod 1104, and at this time the return spring 1105 is stretched and undergoes elastic deformation. When the inclined surfaces of the first inclined plate 1102 and the second inclined plate 1106 are separated, the vertical surface of the second inclined plate 1106 abuts against the vertical surface of the first inclined plate 1102, and the return spring 1105 is reset to fix the rolling curtain 602; when it is necessary to take out the rolling curtain 602, the teacher pulls the connecting rod 1104 to pull the second inclined plate 1106 upward, and at this time the first inclined plate 1102 can be pulled out.

[0035] The above are only the preferred embodiments of the present invention patent, and are not intended to limit the present invention patent. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention patent shall be included in the protection scope of the present invention patent.
