This causes glare from the light source during teaching, making it difficult for some students to see the teaching materials on the screen, thus creating an impact. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional multimedia teaching LED display screen.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional multimedia teaching LED display screen, comprising an LED display screen, a connecting line fixedly connected to the side of the LED display screen, an adjustment device provided on the side of the LED display screen, a connection port opened at the bottom of the LED display screen, an anti-detachment device provided on the surface of the connection port, the adjustment device comprising an L-shaped rod fixedly connected to the side of the LED display screen, a fixing frame provided on the side of the LED display screen, a rectangular frame rotatably connected to the surface of the fixing frame, a fixing rod inserted into the side of the rectangular frame, and the L-shaped rod inserted into the interior of the rectangular frame.
[0006] The aforementioned components achieve the following effects: Under the action of the rectangular frame and L-shaped rod, the LED display screen can rotate on the side of the mounting bracket, thereby adjusting the angle between the LED display screen and the wall and avoiding glare. When the LED display screen is needed, it is fixed to the wall and connected to the power supply via the connecting cable to make the LED display screen light up. Since the LED display screen can project images and connect to a computer to transmit teaching knowledge, it becomes a multi-functional LED display screen.
[0007] Preferably, a rectangular plate is fixedly connected to the side of the LED display screen, a fixed rod is fixedly connected to the side of the rectangular plate, a rectangular rod is rotatably connected to the surface of the fixed rod, a telescopic rod is slidably connected inside the rectangular rod, a circular groove is opened on the surface of the telescopic rod, a locking rod is inserted into the side of the rectangular rod, one end of the locking rod is inserted into the inside of the circular groove, and a rubber block is fixedly connected to one end of the telescopic rod.
[0008] The effect achieved by the above components is that, under the action of the locking rod, after the telescopic rod extends to a suitable length, it can be fixed, thus preventing the telescopic rod from retracting.
[0009] Preferably, a screw is threaded to the side of the rectangular plate, and an extrusion plate is rotatably connected to one end of the screw. An anti-slip strip is fixedly connected to the surface of the extrusion plate.
[0010] The effect achieved by the above components is that, under the action of the screw, the extrusion plate is pushed and pressed against the surface of the rectangular rod, thereby allowing the rectangular rod to be fixed after rotating to a suitable angle.
[0011] Preferably, a sliding rod is fixedly connected to the side of the extrusion plate, and the sliding rod slides on the surface of the rectangular plate.
[0012] The effect achieved by the above components is as follows: Under the action of the sliding rod, the extrusion plate will not rotate with the rotation of the screw. When it is necessary to adjust the angle of the LED display screen, the L-shaped rod on the side of the LED display screen is inserted into the inside of the rectangular frame. The L-shaped rod is fixed inside the rectangular frame by the fixing rod. Since the rectangular frame and the fixing frame are rotatably connected, the LED display screen can be rotated to adjust the angle on the side of the fixing frame. After adjusting to the appropriate position, the rectangular rod is rotated on the surface of the round rod, and the telescopic rod is pulled out from the inside of the rectangular rod. The rubber block at one end of the telescopic rod is pressed against the wall, and the locking rod is inserted into the inside of the round groove, thereby fixing the position of the telescopic rod. The screw is turned by hand, so that the extrusion plate is pressed against the side of the rectangular rod with the cooperation of the sliding rod, thereby fixing the position of the rectangular rod. Thus, the angle adjustment of the LED display screen is completed, thereby avoiding the phenomenon of LED display screen reflection, and thus achieving the purpose of adjusting the angle of the LED display screen.

[0014] The effect achieved by the above components is that, under the action of the magnetic plate, the connection end of the data cable is inserted into the connection port and then restricted by the plate, thus preventing the data cable from separating from the connection port.
[0015] Preferably, a baffle is fixedly connected to the side of the card plate, and the baffle is located at the end of the card plate away from the card slot.
[0016] The effect achieved by the above components is that, under the action of the baffle, the clamping plate will not slide off the surface of the fixed plate, thus avoiding the phenomenon of the clamping plate separating from the fixed plate.
[0017] Preferably, a pad, which is a rubber plate, is fixedly connected to the side of the baffle.
[0018] The effect achieved by the above components is that, under the action of the pad, the baffle will not directly impact the side of the fixed plate, thus avoiding damage to the baffle.
[0019] Preferably, a locking rod is inserted into the side of the fixing plate, and a groove is formed on the side of the locking plate, into which the locking rod is inserted.
[0020] The aforementioned components achieve the following effects: Under the action of the locking lever, the card plates are attracted together by the magnetic plate, allowing the locking lever to be inserted into the groove to secure the card plates. When one end of the data cable needs to be inserted into the connection port, the card plates are pulled to both sides, allowing the connection end to be inserted into the connection port. Under the magnetic attraction of the magnetic plates, the card plates move relative to each other and are attracted together, thus securing the data cable inside the slot. Under the action of the baffle, the card plates will not slide off the surface of the fixing plate, preventing separation of the card plates from the fixing plate. Under the action of the pad, the baffle will not directly impact the side of the fixing plate, preventing damage to the baffle. After the card plates are attracted together, the locking lever, under the action of the locking lever, is attracted together by the magnetic plate, allowing the locking lever to be inserted into the groove to secure the card plates, thereby achieving the function of preventing the data cable from detaching.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting an adjustment device, when the angle of the LED display screen needs to be adjusted, the L-shaped rod on the side of the LED display screen is inserted into the inside of the rectangular frame. The L-shaped rod is fixed inside the rectangular frame by a fixing rod. Since the rectangular frame and the fixing frame are rotatably connected, the LED display screen can be rotated to adjust the angle on the side of the fixing frame. After adjusting to the appropriate position, the rectangular rod is rotated on the surface of the round rod, and the telescopic rod is pulled out from the inside of the rectangular rod. The rubber block at one end of the telescopic rod is pressed against the wall, and the locking rod is inserted into the round groove, thereby fixing the position of the telescopic rod. The screw is turned by hand, so that the pressing plate is pressed against the side of the rectangular rod with the cooperation of the sliding rod, thereby fixing the position of the rectangular rod. Thus, the angle adjustment of the LED display screen is completed, thereby avoiding the phenomenon of LED display screen reflection. This achieves the purpose of adjusting the angle of the LED display screen, thus solving the problem of reflection caused by light source after the display screen is fixed to the wall by the fixing frame.

Under the action of the rectangular frame 23 and the L-shaped rod 22, the LED display screen 1 can rotate on the side of the fixing frame 21, thereby adjusting the angle between the LED display screen 1 and the wall and avoiding glare. When the LED display screen 1 needs to be used, it is fixed to the wall, and the power is turned on through the connecting cable 4, so that the LED display screen 1 emits light. Since the LED display screen 1 can project images, it can be connected to the power supply. The LED display screen 1 transmits teaching knowledge via brain, thus enabling it to function as a multi-functional LED display screen. A rectangular plate 24 is fixedly connected to the side of the LED display screen 1. A fixing rod is fixedly connected to the side of the rectangular plate 24. A rectangular rod 25 is rotatably connected to the surface of the fixing rod. A telescopic rod 26 is slidably connected inside the rectangular rod 25. A circular groove is formed on the surface of the telescopic rod 26. A locking rod 27 is inserted into the side of the rectangular rod 25, with one end of the locking rod 27 inserted into the circular groove. A rubber block is fixedly connected to one end of the telescopic rod 26. Under the action of the locking rod 27, the telescopic rod 26 can be fixed after extending to a suitable length, preventing it from retracting. A screw 28 is threadedly connected to the side of the rectangular plate 24. One end of screw 28 is rotatably connected to a pressing plate 29. An anti-slip strip is fixedly connected to the surface of the pressing plate 29. Under the action of screw 28, the pressing plate 29 is pushed and pressed against the surface of rectangular rod 25, allowing the rectangular rod 25 to rotate to a suitable angle and then be fixed. A sliding rod 210 is fixedly connected to the side of the pressing plate 29. The sliding rod 210 slides on the surface of rectangular plate 24. Under the action of the sliding rod 210, the pressing plate 29 will not rotate with the rotation of screw 28. When the angle of LED display screen 1 needs to be adjusted, the L-shaped rod 22 on the side of LED display screen 1 is inserted into the interior of rectangular frame 23. The L-shaped rod 22 is fixed inside the rectangular frame 23 by a fixing rod. Since the rectangular frame 23 and the fixing bracket 2... 1. A rotating connection is made, allowing the LED display screen 1 to rotate and adjust its angle on the side of the mounting bracket 21. Once adjusted to the appropriate position, the rectangular rod 25 is rotated on the surface of the round rod, and the telescopic rod 26 is pulled out from the inside of the rectangular rod 25. The rubber block at one end of the telescopic rod 26 is then pressed against the wall. The locking rod 27 is inserted into the round groove, thus fixing the position of the telescopic rod 26. The screw 28 is turned by hand, causing the pressing plate 29 to press against the side of the rectangular rod 25 with the cooperation of the sliding rod 210, thereby fixing the position of the rectangular rod 25. This completes the angle adjustment of the LED display screen 1, thus preventing glare from the LED display screen 1 and achieving the purpose of adjusting the angle of the LED display screen 1.
[0030] Reference Figure 4 The anti-detachment device 3 includes a fixing plate 31 fixedly connected to the bottom of the LED display screen 1. A locking plate 32 is slidably connected to the surface of the fixing plate 31. A locking groove is formed on the surface of the locking plate 32. A magnetic plate 35 is fixedly connected to the side of the locking plate 32. Under the action of the magnetic plate 35, the connection end of the data cable is inserted into the connection port and is restricted by the locking plate 32, thus preventing the data cable from separating from the connection port. A baffle 33 is fixedly connected to the side of the locking plate 32. At the end furthest from the slot, the baffle 33 prevents the locking plate 32 from sliding off the surface of the fixing plate 31, thus avoiding separation between the locking plate 32 and the fixing plate 31. A pad 34, made of rubber, is fixedly connected to the side of the baffle 33, preventing the baffle 33 from directly impacting the side of the fixing plate 31 and thus avoiding damage to the baffle 33. A locking rod 36 is inserted into the side of the fixing plate 31, and a groove is formed on the side of the locking plate 32. When inserted into the groove, the locking rod 36 causes the locking plate 32 to be attracted together by the magnetic plate 35. The locking rod 36 can then be inserted into the groove to fix the locking plate 32. When one end of the data cable needs to be inserted into the connection port, the locking plate 32 is pulled to both sides, allowing the connection end to be inserted into the connection port. Under the magnetic attraction of the magnetic plate 35, the locking plates 32 move relative to each other and are attracted together, thus securing the data cable inside the slot. The baffle 33 prevents the locking plate 32 from sliding off the surface of the fixing plate 31, avoiding separation. The pad 34 prevents the baffle 33 from directly impacting the side of the fixing plate 31, preventing damage. After the locking plates 32 are attracted together, the locking rod 36, under the action of the magnetic plate 35, allows the locking rod 36 to be inserted into the groove to fix the locking plate 32, thus achieving the function of preventing the data cable from detaching.
[0031] Working principle: When using the multi-functional multimedia teaching LED display screen 1, fix the LED display screen 1 to the wall and connect it to the power supply via the connecting cable 4 to make the LED display screen 1 emit light. Since the LED display screen 1 can project and connect to a computer to transmit teaching knowledge, it becomes a multi-functional LED display screen 1. When the angle of the LED display screen 1 needs to be adjusted, insert the L-shaped rod 22 on the side of the LED display screen 1 into the inside of the rectangular frame 23. Fix the L-shaped rod 22 inside the rectangular frame 23 with the fixing rod. Since the rectangular frame 23 is rotatably connected to the fixing frame 21, the LED display screen 1 can be rotated and adjusted to the side of the fixing frame 21. After adjusting to the appropriate position, rotate the rectangular rod 25 on the surface of the round rod to pull out the telescopic rod 26 from the inside of the rectangular rod 25, and make the rubber block at one end of the telescopic rod 26 press against the wall. Insert the locking rod 27 into the inside of the round groove to fix the position of the telescopic rod 26. Tighten the screw 28 by hand to make the pressing plate 29 With the cooperation of the slider 210, the slider is pressed against the side of the rectangular bar 25, thereby fixing the position of the rectangular bar 25 and completing the angle adjustment of the LED display screen 1. This avoids the reflection phenomenon of the LED display screen 1, thus achieving the purpose of adjusting the angle of the LED display screen 1. When the connection end of one end of the data cable needs to be inserted into the connection port, the card plate 32 is pulled to both sides, so that the connection end is inserted into the connection port. Under the magnetic attraction of the magnetic plates 35, the card plates 32 move relative to each other and are attracted together, thereby allowing the data to be transferred. The cable is secured inside the slot. Under the action of the baffle 33, the card plate 32 will not slide off the surface of the fixing plate 31, thus preventing the card plate 32 from separating from the fixing plate 31. Under the action of the pad 34, the baffle 33 will not directly impact the side of the fixing plate 31, thus preventing damage to the baffle 33. When the card plates 32 are attracted together, under the action of the locking rod 36, the card plates 32 are attracted together by the magnetic plate 35. The locking rod 36 can then be inserted into the groove to fix the card plates 32, thereby achieving the function of preventing the data cable from getting off.
