[0022] 2. The smart screen for the exhibition hall is equipped with a curved groove. When the first positioning block moves to the bottom of the first vertical groove, the limit block continues to move, causing the first positioning block to move into the curved groove. The curved groove provided on the adjustment housing allows the adjustment housing to move upward while rotating, thereby driving the connector and roller to move, achieving a 180° flip of the connector and roller, making it easier for the roller on the connector to connect to the right-angle slide rail on the other side.

[0023] 3. The smart screen for the exhibition hall is provided with a second vertical slot. When the first positioning block moves to the bottom of the curved slot, as the limit block continues to move, the first positioning block will move into the second vertical slot to achieve repositioning of the connector and the roller, and avoid the automatic rotation of the connector and the roller during the subsequent flipping process. As the limit block moves upward, it will contact and squeeze the first airbag, allowing the gas inside the first airbag to enter the second airbag. The expansion of the second airbag drives the positioning gear ring to move upward, releasing the limit on the rotating gear and the movable column, allowing the movable column in the connecting column to rotate, making it convenient to pull the installation frame later to flip it.

[0042] A slide groove 8 is provided on one side surface of the docking column 4, and a limiting mechanism 9 is provided on the inner side of the docking column 4. The limiting mechanism 9 includes a first positioning block 901 and a rotating rod 902. The end of the first positioning block 901 is movably connected to the rotating rod 902, and the rotating rod 902 is threadedly connected to the docking column 4. An adjustment mechanism 10 is provided on the side of the first positioning block 901. The adjustment mechanism 10 includes an adjustment housing 1001 and a first vertical slot 1002. The first vertical slot 1002 is provided on the surface of the adjustment housing 1001, and the first positioning block 901 is located inside the first vertical slot 1002.

[0043] The first sliding block 11 is fixedly connected to the bottom of the adjustment housing 1001, and a limit block 12 is set on the side of the first sliding block 11. A docking ball 13 is embedded in the limit block 12, and a hydraulic rod 14 is installed at the bottom of the limit block 12;

[0044] The adjustment mechanism 10 further includes a curved groove 1003 and a second vertical groove 1004, wherein the curved groove 1003 is provided at the bottom of the first vertical groove 1002, and the second vertical groove 1004 is provided at the end of the curved groove 1003. The curved groove 1003 and the second vertical groove 1004 are both provided on the surface of the adjustment housing 1001, and the first vertical groove 1002 is connected to the second vertical groove 1004 via the curved groove 1003. The longitudinal cross-section of the first sliding block 11 is arranged in an "L" shape, and the outer surface of the first sliding block 11 is in contact with the outer surface of the docking ball 13, and the docking ball 13 is arranged at an angle.

[0045] First, fix the slide rail 7 on the wall, and lay out the promotional information on the wall. Then, place the rollers 6 provided on both sides of the mounting frame 1 in the slide rail 7. A docking frame 32 is provided on the side of the mounting frame 1. At this time, the rotating wheels 33 on the docking frame 32 will contact the wall. The rollers 6 and rotating wheels 33 in the slide rail 7 ensure the stability of the mounting frame 1 when sliding.

[0046] When the mounting frame 1 needs to be flipped to another wall, the hydraulic rod 14 provided in the docking column 4 is moved. When the hydraulic rod 14 moves upward, it will drive the limit block 12 and the adjustment shell 1001 to slide in the docking column 4, and the limit block 12 is provided in the slide groove 8 provided on the docking column 4. The slide groove 8 is used to limit the movement of the limit block 12, so that the movement of the limit block 12 and the adjustment shell 1001 is more stable, and the inner wall of the docking column 4 is fixed with a first positioning block 901. When the adjustment shell 1001 slides upward, it will drive the first positioning block 901 to slide in the first vertical groove 1002. The setting of the first vertical groove 1002 is used to allow the adjustment shell 1001 to drive the connecting member 5 to slide upward smoothly. As the connecting member 5 moves upward, it will drive the roller 6 to slide on the slide rail 7. When the first positioning block 901 moves to the bottom of the first vertical groove 1002, the roller 6 is separated from the slide rail 7.

[0047] The first vertical slot 1002 provided on the adjusting shell 1001 is used to limit the movement of the adjusting shell 1001 and the connecting member 5, so that the rotation of the connecting member 5 and the roller 6 is locked, which is convenient for maintaining the stability of the roller 6 sliding in the slide rail 7 in the later stage. As the limiting block 12 continues to slide upward, the first positioning block 901 will slide from the first vertical slot 1002 to the curved slot 1003. The setting of the curved slot 1003 provided on the adjusting shell 1001 is used to allow the adjusting shell 1001 to drive the rotation of the connecting member 5 and the roller 6 while rotating. The adjusting shell 1001 slides in the limiting block 12 through the first sliding block 11. A docking ball 13 is provided between the first sliding block 11 and the limiting block 12. The docking ball 13 is used to reduce the friction when the adjusting shell 1001 rotates, so that the adjusting shell 1001 rotates more smoothly.

It should be noted that the intelligent detection technology of the display screen 2 is existing technology. For details, please refer to an intelligent LED display screen (publication number CN102201201B).

[0049] Example 2

[0050] This embodiment is intended to facilitate solving the problem of how to flip the mounting frame 1 without lifting it. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 2 to 8 , the first sliding block 11 is embedded in the interior of the limit block 12, and the limit block 12 and the docking column 4 are slidably connected, and a first airbag 15 is provided on the inner side of the docking column 4, and the first airbag 15 is sleeved on the outside of the connecting member 5, and the connecting member 5 and the adjustment shell 1001 are welded, an air guide tube 16 is provided on the side of the first airbag 15, and the end of the air guide tube 16 is connected to the second airbag 17, and the first airbag 15 is connected to the second airbag 17 through the air guide tube 16, a connecting column 18 is provided on the outside of the second airbag 17, and a docking piece 19 is fitted and connected to the top of the second airbag 17, and the docking piece 19 and the connecting column 18 are slidably connected, and the end of the docking piece 19 is fixedly connected to the positioning gear ring 20;

[0051] A second sliding block 21 is fixedly connected to the outer wall of the positioning gear ring 20, and second positioning blocks 22 are fixedly connected to the outer walls of both sides of the second sliding block 21. A limiting slot 23 is provided on the outer side of the second positioning block 22. At the same time, the limiting slot 23 is opened inside the connecting column 18. A movable column 25 is provided inside the second sliding block 21, and a first spring 24 is provided on the top of the second sliding block 21. The first spring 24 is sleeved on the outside of the movable column 25. A connecting gear 26 is provided at the end of the movable column 25. The connecting gear 26 is embedded in the interior of the positioning gear ring 20, and a rotating shaft 27 is provided at the bottom of the connecting gear 26.

[0052] As the hydraulic rod 14 drives the limit block 12 to continue to move, the first positioning block 901 will slide to the bottom of the curved groove 1003, allowing the adjustment housing 1001 to drive the connecting piece 5 and the roller 6 to rotate 180 degrees. At this time, the limit block 12 continues to move upward, allowing the first positioning block 901 to slide from the curved groove 1003 to the inside of the second vertical groove 1004, allowing the adjustment housing 1001 to rise and fall and rotate, changing to only lifting the adjustment housing 1001, so as to lock the connecting piece 5 and the roller 6 again, and avoid the subsequent movement of the mounting frame 1 due to shaking, which causes the connecting piece 5 and the roller 6 to rotate on their own, and then making it difficult for the subsequent roller 6 to fit into the slide rail 7;

[0053] When the first positioning block 901 slides in the second vertical slot 1004, the regulating housing 1001 contacts the first airbag 15. As the regulating housing 1001 moves upward, the regulating housing 1001 squeezes the first airbag 15, allowing the gas inside the first airbag 15 to enter the second airbag 17 through the air guide tube 16, and allowing the second airbag 17 located in the connecting column 18 to expand. When the second airbag 17 expands, it drives the docking piece 19 and the positioning gear ring 20 located on the top of the second airbag 17 to move upward, and the positioning gear ring 20 is pressed against the first airbag 15. 0 is provided with a second sliding block 21, and second positioning blocks 22 are provided on both sides of the second sliding block 21. When the positioning gear ring 20 slides, the second positioning blocks 22 on both sides of the second sliding block 21 will slide in the limiting sliding grooves 23. The second positioning blocks 22 are used to limit the movement of the positioning gear ring 20. When the second sliding block 21 slides upward, it squeezes the first spring 24 and releases the lock between the positioning gear ring 20 and the connecting gear 26 at the bottom of the movable column 25, allowing the movable column 25 in the connecting column 18 to rotate;

[0054] The space where the slide rail 7 is located at a right angle is much larger than the space for passage on both sides. At this time, by pushing the mounting frame 1, the roller 6 on the connecting column 18 moves to the right angle. By pulling the mounting frame 1, the mounting frame 1 is rotated 45 degrees to the other side of the slide rail 7, and the mounting frame 1 is pulled outward along the 45 degree direction. The inclined surface of the slide rail 7 at 45 degrees is used to realize the steering of the roller 6, so that the roller fits the inclined surface of the slide rail 7. At this time, by applying force to the other side of the slide rail 7, the roller completes the steering and slides. The sliding rail 7 at the other wall is inserted to realize reversing the roller 6 provided at the end of the movable column 25. When the roller 6 provided at the end of the movable column 25 is not moved, the rotation angle of the mounting frame 1 is changed and the mounting frame 1 is flipped. At this time, the roller 6 is located in the sliding rail 7, and the sliding rail 7 has a limiting effect on the roller 6. At this time, the mounting frame 1 is continued to be pulled to allow the mounting frame 1 to continue to rotate with the movable column 25 as the center, and the roller 6 on the connecting member 5 is located directly above the sliding rail 7.

[0055] By adjusting the rotating rod 902 on the docking column 4, the rotating rod 902 and the first positioning block 901 are movably connected, and the rotating rod 902 drives the first positioning block 901 to slide in the docking column 4, so that the first positioning block 901 is separated from the second vertical slot 1004, and the adjusting housing 1001 is driven downward by controlling the hydraulic rod 14, so that the roller 6 at the end of the connecting member 5 is re-engaged in the slide rail 7, and the rotating rod 902 on the other side of the docking column 4 is rotated to make the first positioning block 901 at the end of the rotating rod 902 on the other side engage in the first vertical slot 1002, so that the docking column 4 can be re-engaged in the sliding rail 7. The locking of the adjustment shell 1001 completes the flipping of the mounting frame 1, and when the adjustment shell 1001 moves downward, the squeezing of the first airbag 15 is released, and the reset elastic force of the first spring 24 in the connecting column 18 drives the reset of the positioning gear ring 20 and the second airbag 17, allowing the positioning gear ring 20 to re-lock the connecting gear 26. It should be noted that there are two first positioning blocks 901. When the first positioning block 901 on one side is in a protruding state, the first positioning block 901 on the other side is in a retracted state and does not contact the adjustment shell 1001.

[0056] Example 3

[0057] This embodiment is intended to facilitate solving the problem of how to quickly flip the display screen 2. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 2 and Figures 9 to 11, a positioning ball 28 is provided inside the mounting frame 1, and the positioning ball 28 is fixedly connected to the display screen 2, and a first slide groove 29 is provided on the outside of the positioning ball 28, and a second slide groove 30 is provided on the side of the first slide groove 29, the first slide groove 29 and the second slide groove 30 are both opened inside the mounting frame 1, and a docking frame 32 is fixedly connected to the outer wall of one side of the mounting frame 1, and a rotating wheel 33 is provided on the outside of the docking frame 32, a positioning mechanism 31 is provided on the side of the positioning ball 28, and the positioning mechanism 31 includes a third positioning block 3101, a second spring 3102, a traction wire 3103 and an adjusting disk 3104, and a second spring 3102 is provided at the end of the third positioning block 3101, and the outer surface of the third positioning block 3101 is in contact with the outer surface of the positioning ball 28, a traction wire 3103 is provided through the inside of the second spring 3102, and an adjusting disk 3104 is provided at the end of the traction wire 3103;

[0058] Then, by rotating the adjustment disk 3104 on the mounting frame 1, the adjustment disk 3104 pulls the traction wires 3103 and the third positioning block 3101 on both sides, and squeezes the second spring 3102, so that the third positioning block 3101 is separated from the positioning ball 28 on the display screen 2. By pulling one side of the display screen 2, the positioning ball 28 on one side of the display screen 2 slides out from the second slide groove 30, and then the display screen 2 is rotated with the positioning ball 28 on the other side as the center of the circle. While rotating, a squeezing force is applied to the positioning ball 28. Pressure, as the display screen 2 rotates, when the display screen 2 rotates to a certain angle, the positioning ball 28 slides in the first slide groove 29. When the positioning ball 28 slides to one side of the first slide groove 29, the display screen 2 is pressed into the mounting frame 1, so that the positioning ball exposed on the outside of the display screen 2 is embedded in the first slide groove 29 again through the second slide groove 30, thereby realizing the flipping of the display screen 2 and releasing the external force on the adjustment disk 3104. The reset elastic force of the second spring 3102 drives the third positioning block 3101 to reset, thereby locking the display screen 2 again.
