[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The sub-plate is bent by rotating the rod. When the sub-plate bends towards the connecting frame, the rotating table starts to rotate, so that the contact spring is away from the connecting frame. The contact spring pushes the sliding block one, so that the flexible band is pulled towards the rotating table, thereby making the flexible plate fit towards the main plate. Then, through the limiting of the L-shaped positioning block and the positioning rod, the display frame and the flexible screen fit towards the flexible plate. However, when the sub-plate bends away from the connecting frame, the rotating table is rotated again, so that the contact spring is near the connecting frame. At this time, the contact spring pushes the sliding block one, so that the connecting rope and the flexible band are no longer taut, so that the flexible plate has enough length to bend and will not become a straight plate. Then, through the limiting of the L-shaped positioning block and the positioning rod, the display frame and the flexible screen fit towards the flexible plate. This mechanism reduces the damage to the flexible screen when it bends by bending the flexible plate and contacting the flexible screen.

[0017] 2. The movement of the connecting plate drives the movement of the positioning plate, which in turn drives the movement of the sliding block 2. As the sliding block 2 moves, the rack 1 mounted on its upper end slides on the positioning block. As the rack 1 slides, it drives the gear 2 meshing on one side to rotate. As the gear 2 rotates, the auxiliary wheel 2 between the tough plate and the sub-plate starts to rotate. As the auxiliary wheel 2 rotates, it pulls the tough plate to one side through friction and flattens the tough plate. This mechanism makes the tough plate more smooth when bending and reduces the friction between the tough plate and the main plate and the sub-plate.

[0018] 3. The rotating block is driven by a cylinder, causing the rotating rod to stretch or push the sub-plate. The sub-plate is subjected to the tensile force of the rotating rod and rotates and bends on both sides of the main board, causing the main board and the two sub-plates to continuously change their positions, thereby adjusting the bending arc and direction of the flexible plate. At the same time, while the rotating block is moving, the rack two installed at the upper end of the rotating block drives the gear three to rotate. As the gear three rotates, it pushes the positioning rack to slide. As the positioning rack slides, the positioning wheel slides in the groove of the support frame. The elastic restoring force of the buffer spring allows the connecting frame to rotate and rise or fall accordingly when the sub-plate bends. This mechanism allows the flexible screen to rise or fall accordingly when the bending direction is adjusted to accommodate different crowd sizes. Attached Figure Description

[0036] Specifically, when the auxiliary plate 7 no longer rotates and bends and is in the flush state with the main plate 6, the sliding block one 14 is pushed to the center position of the rotating table 11 by the elastic restoring force of the resisting spring 16, at this time, the rotating shaft of the sliding block one 14 and the connecting plate 15 is concentric with the rotating shaft of the rotating table 11, then when the auxiliary plate 7 needs to bend away from the connecting frame 5, the motor 24 can be started to drive the rotating table 11 to rotate, like Figure 4When the rotating table 11 rotates, the movable groove 30 is pushed out of the groove in the positioning plate two 31 by the resistance of the bevel of the positioning plate two 31, so that the positioning plate two 31 is in contact with the side surface of the contact ring 29, and the positioning plate two 31 is inserted into the groove of the positioning groove 33, so that the connecting plate 15 and the positioning plate one 21 are clamped in place, thereby realizing that the connecting plate 15 and the positioning plate one 21 do not move together when the rotating table 11 rotates. When the rotating table 11 rotates, the sliding block one 14 also rotates on one side of the connecting plate 15. When the rotating table 11 rotates half a circle, the positioning plate two 31 is inserted into the inside of the movable groove 30 again under the elastic restoring force of the reset spring 32. At this time, the connecting plate 15 and the positioning plate one 21 can normally move. However, the direction of the restoring force released by the contact spring 16 is changed, so that the contact spring 16 pushes the sliding block one 14 to move in the direction of the flexible belt 18. At this time, when the auxiliary plate 7 bends away from the connecting frame 5, the flexible plate 8 will not be straightened by the tension of the flexible belt 18, so as to partially fit with the inner side wall of the main plate 6 and the auxiliary plate 7, showing a circular arc shape. At the same time, the display frame 9 is limited by the positioning rod 23 and the L-shaped positioning block 55, so as to fit with the flexible plate 8, so that the flexible screen 10 presents a forward wrapping circular arc shape.

[0037] Further, when the positioning plate one 21 is pushed, the sliding block two 20 also slides. The rack one 40 and the positioning rotating rod 22 also move at the same time when the sliding block two 20 slides in the L-shaped sliding groove 19. The positioning rotating rod 22 is rotationally connected with the display frame 9 through the positioning rod 23, so that the positioning rotating rod 22 is pushed by the positioning plate one 21 when the display frame 9 bends, thereby continuously limiting the display frame 9. At the same time, the limiting groove is opened on the rack one 40, and the limiting block 41 in the groove limits the rack one 40. When the rack one 40 slides, the teeth on one side of the rack one 40 drive the gear two 39 to rotate, and the gear two 39 is fixedly connected with the auxiliary wheel two 37, so that the auxiliary wheel two 37 rotates through the movement of the positioning plate one 21 when the flexible plate 8 needs to recover to a flat state. Through the friction between the auxiliary wheel two 37 and the flexible plate 8, the auxiliary wheel two 37 rotates at the same time as the auxiliary straightens the flexible plate 8, and the excess part of the flexible plate 8 is straightened to the direction of the flexible belt 18, so as to facilitate the stretching of the connecting rope 17. At the same time, when the flexible plate 8 needs to be bent, the auxiliary wheel two 37 rotates in the opposite direction, thereby assisting the flexible plate 8 to pull the flexible belt 18 to one side of the auxiliary plate 7, so that the flexible plate 8 is lengthened at both ends to facilitate bending.

[0038] The inner side wall of the connecting frame 5 is welded with a gas cylinder 42, the output end of the gas cylinder 42 is fixedly installed with a rotating block 43, the two sides of the rotating block 43 are rotatably connected with two rotating rods 44, the end of the rotating rod 44 away from the rotating block 43 is installed with a rotating shaft 45, one end of the rotating shaft 45 is fixedly connected with the secondary plate 7, the side of the adjusting rod two 3 away from the connecting frame 5 is welded with a supporting frame 51, the upper end of the connecting frame 5 is fixedly installed with two sliding racks 46, the inner wall of each sliding rack 46 is slidably connected with a positioning rack 49, one end of the positioning rack 49 close to the adjusting rod two 3 is fixedly installed with a positioning wheel 50, and the positioning wheel 50 is slidably connected in the cavity of the supporting frame 51, the upper end of the connecting frame 5 is fixedly installed with two rack twos 48, each rack two 48 is engaged with the same side gear three 47, the adjusting rod two 3 and the connecting frame 5 are rotatably connected with an extension rod 52, and the outer side wall of the extension rod 52 is sleeved with a buffer spring 53.

[0039] Specifically, there is a gap between the adjusting rod two 3 and the connecting frame 5, when the main plate 6 is impacted upward, the device can be assisted by the buffer spring 53, when the rotating block 43 is driven by the gas cylinder 42 to extend and retract, the secondary plate 7 can be pushed to rotate and bend on both sides of the main plate 6 through the rotating rod 44 and the rotating shaft 45, when the rotating block 43 moves towards the main plate 6, the flexible plate 8 will be in a forward wrapping arc shape, which is suitable for a few people to watch, so that the effect of watching the advertisement is more immersive, and at the same time, the rack two 48 will move when the rotating block 43 moves, the rack two 48 drives the gear three 47 engaged therewith to rotate, the gear three 47 rotates and drives the positioning rack 49 to move away from the main plate 6, at this time, the positioning wheel 50 will slide in the cavity of the supporting frame 51, and the elastic restoring force of the buffer spring 53 makes the connecting frame 5 bend towards the ground around the rotating shaft 4, so as to drive the flexible screen 10 to tilt towards the ground, so that a few pedestrians have a better viewing experience, on the contrary, when the rotating block 43 moves away from the main plate 6, the secondary plate 7 will be pulled by the rotating rod 44 to bend towards the connecting frame 5, so that the flexible screen 10 presents a rear wrapping arc shape, and at the same time, the positioning rack 49 moves towards the main plate 6 through the transmission of the gear three 47, so as to pull the connecting frame 5 and one side of the adjusting rod two 3 through the positioning wheel 50, so that the connecting frame 5 presents a horizontal state, and the screen is also lifted when the flexible screen 10 is in an arc state, so that more people can watch the screen in a crowded place.

[0040] The working principle and usage process of this invention: The cylinder 42 pushes the rotating block 43 to move, so that when the rotating rod 44 stretches or pushes the sub-plate 7, the sub-plate 7 is subjected to the tensile force of the rotating rod 44 and rotates and bends on both sides of the main plate 6, so that the main plate 6 and the two sub-plates 7 continuously change their positions, thereby adjusting the bending arc and bending direction of the tough plate 8. At the same time, while the rotating block 43 is moving, the rack 2 48 installed at the upper end of the rotating block 43 drives the gear 3 47 to rotate. While the gear 3 47 is rotating, it pushes the positioning rack 49 to slide. As the positioning rack 49 slides, the positioning wheel 50 will slide in the groove of the support frame 51. Through the elastic restoring force of the buffer spring 53, the connecting frame 5 can rotate and lift or lower according to the bending direction of the sub-plate 7 when the sub-plate 7 is bent.

[0041] Subsequently, during the bending process of the sub-plate 7, when the sub-plate 7 bends towards the connecting frame 5, the rotating table 11 begins to rotate. When the contact spring 16 rotates to the side away from the connecting frame 5, as... Figure 3 As shown, the sliding block 14 is pushed by the abutment spring 16, causing the flexible band 18 to be pulled towards the rotating table 11, thereby causing the flexible plate 8 to adhere to the main plate 6. Then, the display frame 9 and the flexible screen 10 are adhered to one side of the flexible plate 8 by the limiting of the L-shaped positioning block 55 and the positioning rod 23. However, when the sub-plate 7 bends away from the connecting frame 5, the rotating table 11 is rotated again, causing the abutment spring 16 to rotate to the side closer to the connecting frame 5. Figure 5 As shown, at this time, the contact spring 16 pushes the sliding block 14 so that the connecting rope 17 and the flexible band 18 are no longer taut, so that the flexible plate 8 has enough length to bend and will not be taut into a straight plate. Then, through the limiting of the L-shaped positioning block 55 and the positioning rod 23, the display frame 9 and the flexible screen 10 are attached to one side of the flexible plate 8.

[0042] Then, when the connecting plate 15 moves, it drives the positioning plate 21 to move. The positioning plate 21 then drives the sliding block 20 to move. When the sliding block 20 moves, the rack 40 installed on its upper end slides on the positioning block 41. When the rack 40 slides, it drives the gear 39 meshing on one side to rotate. When the gear 39 rotates, the auxiliary wheel 37 between the flexible plate 8 and the sub-plate 7 starts to rotate. When the auxiliary wheel 37 rotates, it pulls the flexible plate 8 to one side through friction and flattens the flexible plate 8.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
