[0003] The multi-module English teaching device currently used has a fixed support structure at the bottom, which stably supports it on the placement surface. However, after the device is used, the mobile device needs to lift it up, which is quite laborious. The support structure with rollers is prone to offset and sliding when in use or writing materials, affecting the stability of subsequent use of the device.

[0004] Summary of the Invention

[0005] The purpose of the present invention is to provide a multimodal English teaching device with a support structure to solve the problem of the currently used multi-module English teaching device proposed in the above background technology. The support structure at the bottom is fixedly set, and it is stably supported on the placement surface by the support structure. However, after the device is used, the mobile device needs to lift it, which is relatively laborious. The support structure with rollers is prone to the problem of the device being offset and sliding when in use or writing materials.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a multimodal English teaching device with a support structure, comprising a base, a supporting column fixed above the base, and a mounting frame fixed above the supporting column, and a teaching display provided inside the mounting frame for playing English teaching materials, a word writing board provided on the front side of the mounting frame to block the teaching display, and an up-and-down sliding structure is formed between the word writing board and the supporting column so that the word writing board can be lowered to the bottom of the teaching display, a movement control mechanism is provided on the rear side of the word writing board to control the movement of the word writing board on the supporting column, a support block is provided below the base, and a walking wheel is rotatably installed on the bottom of the support block to assist the movement of the base, an up-and-down sliding structure is formed between the support block and the base, and a control panel is fixed above the support block to control the movement of the support block through the control panel, a height adjustment mechanism is connected to the middle of the control panel to control the height of the control panel and the support block.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] (1) The support block provides installation space for the travel wheel, and the control device can be conveniently moved by contact between the travel wheel and the support surface. The support block can be moved within the base. After the support block is folded upward, the base can be stably placed on the support surface, thereby providing a stable support effect for the installation frame and the teaching display, ensuring its stability in subsequent use;

[0009] (2) The vertical position of the control panel can be controlled by rotating the control lever. When the control panel moves, the four groups of support blocks can be controlled synchronously, making the position control of the support blocks more convenient and quick, thereby improving the ease of use of the device;

[0010] (3) The word writing board can provide protection for the teaching display, and the word writing board can also be used for writing teaching. When using the teaching display, the word writing board can be moved and pulled down, and the relevant materials can also be annotated on the word writing board in conjunction with the teaching display, which is more flexible to use;

[0011] (4) The movement of the slider can be positioned by the magnetic attraction block, so that the word writing board can maintain its own position stability after moving downward. After the magnetic attraction block is released from the attraction of the slider, the torsion spring drives the reel to rotate, which can automatically drive the word writing board upward and reset it;

[0012] (5) The movement of the word writing board can be locked by a locking mechanism, and the word writing board can be kept stable when the device is moved. After the support block is folded up, the locking mechanism can be automatically unlocked, so that the word writing board can restore its movable state when the device is used for teaching.

[0020] Referring to Figures 1-6 , the present invention provides the following technical solution: a multimodal English teaching device having a support structure, comprising a base 1, a support column 2 being fixed above the base 1, a mounting frame 3 being fixed above the support column 2, and a teaching display 4 being provided within the mounting frame 3 for playing English teaching materials;

[0021] Example 1:

[0022] As shown in FIG1 to FIG4 , the present invention provides a technical solution: a multimodal English teaching device with a support structure, which discloses:

[0023] The front side of the mounting frame 3 is provided with a word writing board 5 to block the teaching display 4, and an up-and-down sliding structure is formed between the word writing board 5 and the supporting column 2, so that the word writing board 5 can be lowered to the bottom of the teaching display 4. A movement control mechanism is provided on the rear side of the word writing board 5 to control the movement of the word writing board 5 on the supporting column 2. A support block 6 is provided under the base 1, and a running wheel 7 is rotatably installed at the bottom of the support block 6 to assist the movement of the base 1 through the running wheel 7. An up-and-down sliding structure is formed between the support block 6 and the base 1, and a control board 8 is fixed above the support block 6, and the movement of the support block 6 is controlled by the control board 8. A height adjustment mechanism is connected to the middle part of the control board 8 to control the height of the control board 8 and the support block 6. The height adjustment mechanism is composed of a control rod 9, which is rotatably installed above the base 1, and the control rod 9 passes through the control board 8 and the control board 8 to form a threaded connection. There are four groups of support blocks 6 evenly distributed under the base 1, and a stabilizing seat 10 is fixed under the base 1, and the stabilizing seat 10 is made of rubber material;

[0024] English teaching materials can be played and displayed through the teaching display 4, and corresponding writing records can be made on the word writing board 5. When the device needs to be moved, the control rod 9 can be rotated so that the control rod 9 drives the control board 8 to move through the threaded connection between the control rod 9 and the control board 8. The control board 8 drives the support block 6 to move, so that the walking wheel 7 under the support block 6 props up the base 1. At this time, the device can be pushed to move conveniently. After moving to the specified position, the control rod 9 can be rotated in the opposite direction to control the support block 6 to move upward, so that the stabilizing seat 10 contacts the supporting surface, providing stable support for the base 1 and the supporting column 2, and avoiding sliding deviation during the use of the device.

[0025] Example 2:

[0026] As shown in FIG5-6, based on the first embodiment, the present invention provides a technical solution: a multimodal English teaching device with a support structure, which discloses:

[0027] The mobile control mechanism includes a slider 11, a control rope 12, a winding shaft 13 and a torsion spring 14. The slider 11 is fixed to the rear side of the word writing board 5, and the top cross-section of the slider 11 is a "T"-shaped structure design, and the slider 11 is located inside the support column 2 and between the support column 2 to form an up and down sliding structure. The control rope 12 is fixed above the slider 11 to provide an upward pulling force for the slider 11. The winding shaft 13 is rotatably installed inside the support column 2. The upper end of the control rope 12 is wound around the surface of the winding shaft 13. The torsion spring 14 is installed at the end of the winding shaft 13 to provide a rotational reset force for the winding shaft 13. The slider 11 is made of magnetic material. A magnetic attraction block 15 is fixed inside the support column 2. When the slider 11 moves to the magnetic attraction block 15, it is attracted by the magnetic attraction block 15 to position the word writing board 5.

[0028] When the teaching display 4 is needed, the word writing board 5 can be pushed downward to expose the teaching display 4. The word writing board 5 drives the slider 11 to slide in the support column 2. At the same time, the slider 11 pulls the control rope 12 to unwind on the reel 13. The torsion spring 14 accumulates force to move the word writing board 5 to the lowest position. The slider 11 contacts the magnetic attraction block 15. The magnetic attraction block 15 attracts the slider 11. The attraction between the magnetic attraction block 15 and the slider 11 is greater than the elastic force of the torsion spring 14, so that the word writing board 5 can remain stable under the teaching display 4. When the word writing board 5 needs to be folded up later, the word writing board 5 can be pushed upward to release the attraction effect of the magnetic attraction block 15 on the slider 11. The torsion spring 14 can drive the reel 13 to rotate to rewind the control rope 12, and pull the slider 11 upward to reset the word writing board 5.

[0029] Example 3:

[0030] As shown in FIG5-6, based on the second embodiment, the present invention provides a technical solution: a multimodal English teaching device with a support structure, which discloses:

[0031] A locking mechanism is provided on the outer side of the slider 11. After the support block 6 props up the base 1, the slider 11 is locked, so that the word writing board 5 remains stable. The locking mechanism includes a locking groove 16, a locking block 17, a return spring 18, a first magnetic block 19, a second magnetic block 20 and a support plate 21. The locking groove 16 is opened on the side surface of the slider 11, the locking block 17 is arranged inside the supporting column 2, and a concave-convex matching structure is formed between the locking block 17 and the locking groove 16. The return spring 18 is arranged on the outer side of the locking block 17 to provide thrust for the locking block 17. The first magnetic block 19 is fixed to the outer side of the locking block 17, and the second magnetic block 20 is arranged on the outer side of the supporting column 2, and the second magnetic block 20 and the first magnetic block 19 are arranged with opposite magnetic poles relative to each other, so that they can attract the first magnetic block 19 to drive the locking block 17 to move. The support plate 21 is fixed on the outer side of the second magnetic block 20, and the lower end of the support plate 21 is fixedly connected to the control board 8;

[0032] When the support block 6 is raised, the device remains stably placed. At this time, the second magnetic block 20 and the first magnetic block 19 are opposite to each other, and the first magnetic block 19 is attracted to move, compressing the reset spring 18, and the slider 11 can move in the support column 2. When the device is moved, the support block 6 is lowered. At this time, the control board 8 will synchronously drive the second magnetic block 20 to move downward through the support plate 21, so that the positions of the second magnetic block 20 and the first magnetic block 19 are staggered, and the reset spring 18 will push the locking block 17 to move, so that the locking block 17 and the locking groove 16 are connected, locking the movement of the word writing board 5 to prevent the teaching display 4 from leaking out when the word writing board 5 moves during the movement, so that the teaching display 4 can be stably protected during movement, and it also prevents the hand from slipping when holding the word writing board 5 during movement.
