[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. Through the design of the docking rod, the first extension plate, the lifting mechanism, the pushing mechanism and the sleeving mechanism, when installing the LED display screen, the staff can pull the two groups of lifting mechanisms according to the size of the LED display screen to drive the sleeving mechanism to slide from the inner end to the outer end on the outer surface of the first extension plate. Thus, the length of the LED display screen that the sleeving mechanism can sleeve is increased. Until it is adjusted to match the size of the LED display screen, the staff can slide the LED display screen into the U-shaped sleeving mechanism. By adjusting the shape and size of the sleeving mechanism to match the LED display screen, it can ensure that the LED display screen can be completely sleeved in the sleeving mechanism. This can reduce errors and mismatching problems during the installation process, improve the installation accuracy, and no tools are required during the installation process. After the LED display screen is sleeved, the sleeving mechanism can be locked at the current position on the outer surface of the first extension plate. Before locking the sleeving mechanism, the sleeving mechanism can be pushed towards the center to press against both sides of the LED display screen to clamp it. Thus, the LED display screen is enclosed inside. When the LED display screen needs to be disassembled and replaced, the staff only needs to unlock the sleeving mechanism from the outer surface of the first extension plate, and then the LED display screen can be pulled out from it. Thus, it has the function of conveniently disassembling and assembling the LED display screen. After the LED display screen is installed, the staff can also start the lifting mechanism and the pushing mechanism. The lifting mechanism can push the sleeving mechanism vertically upward to drive the LED display screen sleeved inside to perform a height lifting operation. The pushing mechanism can push the lifting mechanism to rotate on the outer surface of the first docking plate on the upper surface of the docking rod. Thus, the lifting mechanism can drive the LED display screen in the sleeving mechanism to adjust the inclination. Thus, the teacher can adjust the height and angle of the LED display screen at any time according to different teaching needs and activity types, making the teaching content more targeted and interactive. And students of different heights are in different positions in the classroom. By adjusting the height and inclination of the LED display screen, it can ensure that all students can clearly see the screen content, enhancing the sense of participation. And the forms of teaching activities are diverse, such as group discussions, speeches, experimental demonstrations, etc. The flexible height and angle adjustments enable the device to quickly adapt to various scenarios and improve the teaching efficiency.

[0023] 2. Through the design of the first electric push rod, the second docking plate, the connecting plate and the third docking plate, when the inclination angle of the LED display screen needs to be adjusted, the first electric push rod can be started to drive the connecting plate at one end of the piston rod to push or pull the third docking plate at one end of the connecting tube, so that the connecting tube can be rotated on the surface of the first docking plate through the fourth docking plate on the lower surface, so that the connecting tube drives the internal sliding installation of the set mechanism to adjust the inclination of the LED display screen. By adjusting the inclination of the LED display screen, customized display effects under different scenes and needs can be met, and the adaptability of the LED display screen is improved. The adjustment of the inclination can allow the LED display screen to obtain the best visual effect at a specific angle, ensuring that students can clearly see the screen content at different positions.

[0024] 3. Through the design of the connecting tube, the second electric push rod and the mounting plate, when the height position of the LED display screen needs to be adjusted, the second electric push rod can be started to push the mounting plate on the lower surface of the piston rod to the lower surface of the connecting tube, and the piston rod of the second electric push rod is fixedly installed in the connecting tube through the mounting plate, so that the second electric push rod can push the extension tube in the set mechanism to slide upward from the connecting tube, thereby realizing the function of pushing the set mechanism to increase or decrease the height, and the set mechanism can drive the LED display screen inside to move up and down, so that it can freely adjust the height position of the LED display screen according to the needs of different occasions, ensuring that all students can clearly see the screen content, adapting to different teaching and demonstration needs, and ensuring that the audience can get the best visual experience at different positions, improving the visibility and viewing effect of the teaching equipment, and the flexible adjustment of the height of the LED display screen makes it suitable for different teaching modes and demonstration activities, increasing the flexibility and versatility of the equipment.

[0025] 4. Through the design of the first connecting arm, the second connecting arm, the first butterfly bolt, the second extension plate, the long strip, the second butterfly bolt and the embedded groove, when installing the LED display screen, the staff can pull the two sets of handles according to the size of the LED display screen to drive the two sets of extension tubes inserted in the connecting tubes to move, and the two sets of extension tubes will drive the two sets of second connecting arms to slide outwards inside the outer surface of the first extension plate, thereby increasing the distance between the two sets of first connecting arms, until it is pulled to match the length of the LED display screen to be installed, and then stop. The staff can also loosen the second butterfly bolt to pull the second extension plate to slide up in the first connecting arm, thereby increasing the length of the first connecting arm to match the width of the LED display screen, and then tighten the second butterfly bolt to lock the second extension plate in the current position, and then the staff can insert the LED display screen into the U-shaped frame formed by the first connecting arm, the second connecting arm and the first extension plate, and the U-shaped inner surface is provided with an embedded groove, and then the outer shell of the LED display screen can be inserted into the embedded groove so that the screen is located outside the U-shaped frame. After the LED display screen is installed, the connecting tube can be pushed toward the center again to drive the two sets of first connecting arms to clamp toward the center, so that the two sets of first connecting arms can clamp the LED display screen at the center, and then the first butterfly bolt can be tightened, so that the threaded portion of the first butterfly bolt can be pressed against one end of the first extension plate, so as to achieve the locking of the two sets of first connecting arms at the current position of the outer surface of the first extension plate, and the set operation of the LED display screen can be completed. When the LED display screen needs to be replaced, the staff only needs to loosen the first butterfly bolt and pull the two sets of first connecting arms toward the outer ends to release the clamping of the LED display screen, so that the staff can pull the LED display screen out from it, which completes the purpose of disassembly. In the process of installing and disassembling the LED display screen, no tools are required, making the installation and disassembly process faster, and the operation without tools reduces the possible accident risks in the use of tools, so that it can quickly complete the installation and disassembly of the LED display screen in various environments, without being restricted by tool availability, and improves the ability to respond to emergencies.

[0127] Through the design of the connecting cylinder 201, the second electric push rod 205 and the mounting plate 206, when the height position of the LED display screen 5 needs to be adjusted, the second electric push rod 205 can be started to push against the lower surface within the connecting cylinder 201 through the mounting plate 206 on the lower surface of the piston rod, and the piston rod of the second electric push rod 205 is fixedly installed within the connecting cylinder 201 through the mounting plate 206. Then, the second electric push rod 205 can push the extension cylinder 402 in the set mechanism 4 to slide upward from within the connecting cylinder 201, and then the function of pushing the set mechanism 4 to lift or lower in height is realized. The set mechanism 4 can drive the internally set LED display screen 5 to move up and down, so that it can freely adjust the height position of the LED display screen 5 according to the needs of different occasions, ensure that all students can clearly see the screen content, adapt to different teaching and demonstration needs, and can also ensure that the audience can obtain the best visual experience at different positions, improving the visibility and viewing effect of the teaching equipment. Moreover, the flexible adjustment of the height of the LED display screen 5 makes it suitable for different teaching modes and demonstration activities, increasing the flexibility and versatility of the equipment.

[0128] As Figure 6-Figure 7 shown, the set mechanism 4 includes an extension cylinder 402. The extension cylinder 402 is slidably installed within the connecting cylinder 201, the extension cylinder 402 is sleeved on the outer surface of the second electric push rod 205 and fixedly installed at the upper surface of the second electric push rod 205. A first connecting arm 401 is fixedly installed on the upper surface of the extension cylinder 402. One end of the first connecting arm 401 is fixedly installed with a second connecting arm 403. The first connecting arm 401 passes through the outer surface of the first extension plate 104 through the second connecting arm 403. Embedded grooves 408 are provided on the first connecting arm 401, the second connecting arm 403 and the first extension plate 104. The embedded grooves 408 on the first connecting arm 401, the second connecting arm 403 and the first extension plate 104 form a U shape, and the U-shaped embedded groove 408 can allow the LED display screen 5 to slide in.

[0129] The extension tube 402 can slide on the outer surface of the first extension plate 104 by being pulled or pushed by the handle 202, thereby forming a clamping and spacing adjustment function for the LED display, thereby increasing the adaptability of the LED display set.

[0130] A first butterfly bolt 404 is threadedly installed at one end of the second connecting arm 403 , and the threaded portion of the first butterfly bolt 404 can press against one end of the first extension plate 104 to lock the second connecting arm 403 at the current position on the outer surface of the first extension plate 104 .

[0131] A second extension plate 405 is slidably mounted on the inner upper surface of the first connecting arm 401. The second extension plate 405 can be slid out of the first connecting arm 401 to extend the width of the LED display screen 5.

[0132] Among them, a second butterfly bolt 407 is threadedly installed at one end of the second extension plate 405, and the threaded portion of the second butterfly bolt 407 passes through the long strip opening 406, so that the hexagonal head of the second butterfly bolt 407 can be threadedly pressed against one end of the first connecting arm 401 to apply a locking effect to the second extension plate 405 that slips out of the first connecting arm 401.

[0133] Through the design of the first connecting arm 401, the second connecting arm 403, the first butterfly bolt 404, the second extension plate 405, the long strip 406, the second butterfly bolt 407 and the embedded groove 408, when installing the LED display screen 5, the staff can pull the two sets of handles 202 according to the size of the LED display screen 5 to drive the extension tubes 402 slidably inserted in the two sets of connecting tubes 201 to move, and the two sets of extension tubes 402 will drive the two sets of second connecting arms 403 to slide outward on the outer surface of the first extension plate 104, thereby increasing the distance between the two sets of first connecting arms 401 until they are pulled to the LED display screen 5 to be installed. After the lengths of the LED display screen 5 match, the LED display screen 5 can be stopped. Then, the staff can loosen the second butterfly bolt 407 to pull the second extension plate 405 to slide up in the first connecting arm 401, thereby increasing the length of the first connecting arm 401 to match the width of the LED display screen 5. Then, the second butterfly bolt 407 can be tightened to lock the second extension plate 405 in the current position. Then, the staff can slide the LED display screen 5 into the U-shaped frame formed by the first connecting arm 401, the second connecting arm 403 and the first extension plate 104, and the inner surface of the U-shaped frame is provided with an embedded groove 408, thereby the LED display screen 5 can be moved upward. The outer shell is inserted into the embedded groove 408 so that the screen is located outside the U-shaped frame. After the LED display screen 5 is installed, the connecting tube 201 can be pushed toward the center again to drive the two sets of first connecting arms 401 to clamp toward the center, so that the two sets of first connecting arms 401 can clamp the LED display screen 5 at the center, and then the first butterfly bolt 404 can be tightened, so that the threaded portion of the first butterfly bolt 404 can be pressed against one end of the first extension plate 104, so that the two sets of first connecting arms 401 are locked at the current position of the outer surface of the first extension plate 104, and the assembly operation of the LED display screen 5 is completed. When replacing the LED display screen 5, the staff only needs to loosen the first butterfly bolt 404 and pull the two sets of first connecting arms 401 outward to release the clamping of the LED display screen 5, so that the staff can pull the LED display screen 5 out, thus completing the purpose of disassembly. During the installation and removal of the LED display screen 5, no tools are required, making the installation and removal process faster. The absence of tool operation reduces the possible risk of accidents in the use of tools, and enables the LED display screen 5 to be quickly installed and removed in various environments without being restricted by tool availability, thereby improving the ability to deal with emergencies.

[0134] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when installing the LED display screen 5, the staff can pull the two sets of handles 202 according to the size of the LED display screen 5 to drive the extension tubes 402 inserted into the two sets of connecting tubes 201 to move, and the two sets of extension tubes 402 will drive the two sets of second connecting arms 403 to slide outward from the outer surface of the first extension plate 104, thereby increasing the spacing between the two sets of first connecting arms 401, and stop after pulling to match the length of the LED display screen 5 to be installed, and then the staff can loosen the second butterfly bolt 407 to pull the second extension plate 405 to slide up in the first connecting arm 401, thereby increasing the length of the first connecting arm 401. The second butterfly bolt 407 can be tightened to lock the second extension plate 405 in the current position, and then the staff can slide the LED display screen 5 into the U-shaped frame formed by the first connecting arm 401, the second connecting arm 403 and the first extension plate 104, and the inner surface of the U-shaped frame is provided with an embedded groove 408, so that the outer shell of the LED display screen 5 can be inserted into the embedded groove 408 so that the screen is located outside the U-shaped frame. After the LED display screen 5 is inserted, the connecting cylinder 201 can be pushed toward the center again to drive the two sets of first connecting arms 401 to clamp toward the center, so that the two sets of first connecting arms 401 can clamp the LED display screen 5 at the center. The first butterfly bolt 404 can be tightened, and then the first butterfly bolt 404 can be tightened, so that the threaded portion of the first butterfly bolt 404 can be pressed against one end of the first extension plate 104, thereby locking the two sets of first connecting arms 401 to the current position of the outer surface of the first extension plate 104, and the assembly operation of the LED display screen 5 can be completed. When the inclination angle of the LED display screen 5 needs to be adjusted, the first electric push rod 302 can be started to drive the connecting disk 303 at one end of the piston rod to push or pull the third docking disk 304 at one end of the connecting cylinder 201, so that the connecting cylinder 201 can be rotated on the surface of the first docking disk 102 through the fourth docking disk 204 on the lower surface, thereby achieving the connection cylinder 201 with internal sliding installation. The extension tube 402 rotates, and then the extension tube 402 can drive the LED display screen 5 installed in the first connecting arm 401 and the second connecting arm 403 to adjust the inclination, so that the teacher can adjust the height and angle of the LED display screen 5 at any time according to different teaching needs and activity types, so that the teaching content is more targeted and interactive. After the inclination is adjusted, the second electric push rod 205 can be started to push the mounting plate 206 on the lower surface of the piston rod against the lower surface of the connecting tube 201, and the piston rod of the second electric push rod 205 is fixedly installed in the connecting tube 201 through the mounting plate 206, so that the second electric push rod 205 can push the extension tube 402 to slide upward from the connecting tube 201.Then, the extension tube 402 can push the LED display screen 5 installed in the first connecting arm 401 and the second connecting arm 403 to raise or lower the height, so that the height position of the LED display screen 5 can be freely adjusted according to the needs of different occasions, ensuring that all students can clearly see the screen content and adapting to different teaching and demonstration needs.

[0135] In summary: the on-site interactive teaching device of smart education does not require the use of any tools during the installation and removal of the LED display screen 5, making the installation and removal process faster, and the lack of tool operation reduces the risk of accidents in the use of tools, enabling the LED display screen 5 to be quickly installed and removed in various environments without being restricted by tool availability, thereby improving the ability to respond to emergencies, and the ability to adjust the inclination and height of the LED display screen 5 can better adapt to different teaching scenarios and needs, ensuring that all students can clearly see the content on the screen, thereby improving the inclusiveness and popularity of teaching, and secondly, appropriate inclination and height adjustment can reduce students' visual fatigue when watching the screen for a long time, protecting students' eyesight health.
