Description

Technical Field

[0001] The present invention relates to the technical field of advertising display screens, and in particular to a wall-mounted intelligent advertising display device. Background Art

[0002] Wall-mounted advertising equipment integrates the display and the player into a whole. The player is connected to the playback content through storage devices, networks, WIFI and other methods to achieve online and cross-play functions.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Push the sub-plate to bend by the rotating rod. When the sub-plate bends in the direction close to the connecting frame, the rotating table starts to rotate, so that the resistance spring is on the side away from the connecting frame. The resistance spring pushes the sliding block 1, so that the flexible belt is pulled in the direction of the rotating table, so that the flexible plate is fitted in the direction of the main board. Then, the L-shaped positioning block and the positioning rod are limited, so that the display frame and the flexible screen are fitted to one side of the flexible plate. However, when the sub-plate is bent in the direction away from the connecting frame, the rotating table is rotated again, so that the resistance spring is on the side close to the connecting frame. At this time, the resistance spring pushes the sliding block 1 so that the connecting rope and the flexible belt are no longer stretched straight, so that the flexible plate has sufficient length for bending and will not be stretched into a straight plate. Then, the L-shaped positioning block and the positioning rod are limited, so that the display frame and the flexible screen are fitted to one side of the flexible plate. This mechanism reduces the damage to the flexible screen when it is bent by bending the flexible plate and resisting the flexible screen.

[0017] 2. The positioning plate is driven to move by the movement of the connecting plate, and the positioning plate drives the sliding block 2 to move. When the sliding block 2 moves, the rack 1 installed on its upper end slides on the positioning block. The rack 1 slides and drives the meshing gear 2 on one side to rotate. When the gear 2 rotates, the auxiliary wheel 2 between the tough plate and the auxiliary plate starts to rotate. When the auxiliary wheel 2 rotates, it pulls the tough plate to stretch to one side through friction and flattens the tough plate. This mechanism makes the tough plate smoother when it bends, and reduces the friction between the tough plate and the main plate and the auxiliary plate.

[0018] 3. The cylinder pushes the rotating block to move, so that when the rotating rod stretches or pushes the sub-plate, the sub-plate rotates and bends on both sides of the main board due to the tensile force of the rotating rod, so that the main board and the two sub-plates constantly change their positions, thereby adjusting the bending curvature and bending direction of the flexible plate. At the same time, when the rotating block moves, the rack two installed on the upper end of the rotating block drives the gear three to rotate, and the gear three rotates while pushing the positioning rack to slide. As the positioning rack slides, the positioning wheel will slide in the groove of the support frame. Through the elastic restoring force of the buffer spring, the connecting frame can generate corresponding rotation and rise or fall according to the bending direction of the sub-plate when the sub-plate is bent. This mechanism enables the flexible screen to rise or fall to cope with different crowd sizes when adjusting the bending direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Specifically, mounting grooves are provided at the four corners of the fixing plate 1, and the fixing plate 1 can be fixed to the top of the indoor wall by means of connecting structures such as screws.

The gear 1 28 is fixedly installed with a pulley 26 on the side away from the auxiliary plate 7. The pulley 26 and the pulley 1 25 are jointly sleeved with a transmission belt 27. The end of the rotating table 11 away from the gear ring 34 is fixedly installed with a contact ring 29, and the contact ring 29 rotates in the auxiliary plate 7. The upper and lower ends of the contact ring 29 are provided with movable grooves 30. The inner wall of the movable groove 30 is slidably connected with a positioning plate 21. The contact surface of the positioning plate 21 and the movable groove 30 is provided with a bevel. When the contact ring 29 rotates, the positioning plate 21 will be pushed out of the groove of the movable groove 30 through the bevel, and the positioning plate The second block 31 slides on the outer wall of the auxiliary plate 7, and return springs 32 are installed on both sides of the positioning plate 21, and the other end of the return spring 32 is connected to the auxiliary plate 7. A positioning groove 33 is penetrated through the outer wall of the positioning plate 21, and the positioning groove 33 can be movably connected with the positioning plate 21. A rack 40 is fixedly installed on the upper end of the sliding block 20, and a positioning block 41 is slidably connected to the inner wall of the rack 40, and the positioning block 41 is fixedly connected to the auxiliary plate 7, a gear 2 39 is meshed with one side of the rack 40, and an auxiliary wheel 2 37 is fixedly installed on the lower end of the gear 2 39, and the auxiliary wheel 2 37 is rotatably connected to the outer wall of the auxiliary plate 7.

[0036] Specifically, when the auxiliary plate 7 no longer rotates and bends and is flush with the main plate 6, the sliding block 14 is pushed to the center of the rotating table 11 by the elastic restoring force of the resistance spring 16. At this time, the rotating axis of the sliding block 14 and the connecting plate 15 is concentric with the rotating axis of the rotating table 11. Then, when the auxiliary plate 7 needs to bend in a direction away from the connecting frame 5, the motor 24 can be started to drive the rotating table 11 to rotate. Figure 4As shown, when the rotating table 11 rotates, the movable groove 30 will be pushed out from the groove of the second positioning plate 31 through the interference between the movable groove 30 and the oblique edge of the positioning plate 2 31, so that the second positioning plate 31 is in contact with the side surface of the interference ring 29, and the second positioning plate 31 is inserted into the groove of the positioning groove 33, so that the connecting plate 15 and the positioning plate 1 21 are stuck in place, so that when the rotating table 11 rotates, the connecting plate 15 and the positioning plate 1 21 will not be driven to move together. When the rotating table 11 rotates, the sliding block 14 also rotates on one side of the connecting plate 15. When the rotating table 11 rotates half a circle, the positioning plate 2 31 is subjected to the elastic restoring force of the reset spring 32 and will be inserted into the movable groove again 30, at this time, the connecting plate 15 and the positioning plate 21 can move normally, but the direction of the restoring force released by the resistance spring 16 is reversed, so that the resistance spring 16 will push the sliding block 14 to move in the direction of the flexible belt 18, and the connecting rope 17 will no longer be tight when the sliding block 14 moves. At this time, when the sub-plate 7 is bent in the direction away from the connecting frame 5, the flexible plate 8 will no longer be stretched by the tension of the flexible belt 18, so that it fits with the inner wall part of the main plate 6 and the sub-plate 7 to present an 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 that it fits with the flexible plate 8, so that the flexible screen 10 is in the shape of an arc wrapped forward.

[0037] Furthermore, when the positioning plate 1 21 is pushed, the sliding block 20 will be driven to slide together. When the sliding block 20 slides in the L-shaped sliding groove 19, the rack 1 40 and the positioning rotating rod 22 will also move. The positioning rotating rod 22 is rotatably connected to the display frame 9 through the positioning rod 23, so that when the display frame 9 is bent, the positioning rotating rod 22 will also be pushed by the positioning plate 1 21, thereby continuously limiting the display frame 9. At the same time, a limiting groove is provided on the rack 1 40, and the positioning block 41 in the groove limits the rack 1 40. When the rack 1 40 slides, the teeth on one side of the rack 1 40 will drive the gear 2 39 meshing with it to rotate. The auxiliary wheel 2 37 rotates, and the gear 2 39 is fixedly connected to the auxiliary wheel 2 37, so that whenever the tough plate 8 needs to restore the straight state, the movable auxiliary wheel 2 37 through the positioning plate 1 21 will rotate, and the friction between the auxiliary wheel 2 37 and the tough plate 8 makes the auxiliary wheel 2 37 assist in straightening the tough plate 8 while rotating, and at the same time, the excess part of the tough plate 8 is straightened in the direction of the flexible belt 18, so as to facilitate the stretching of the connecting rope 17. At the same time, when the tough plate 8 needs to be bent, the auxiliary wheel 2 37 will rotate in the opposite direction, so as to assist the tough plate 8 to pull the flexible belt 18 to one side of the sub-plate 7, so that the two ends of the tough plate 8 are lengthened for easy bending.

[0038] A cylinder 42 is welded to the inner wall of the connecting frame 5, and a rotating block 43 is fixedly installed at the output end of the cylinder 42. Two rotating rods 44 are rotatably connected on both sides of the rotating block 43. A rotating shaft 45 is installed at one end of the rotating rod 44 away from the rotating block 43, and one end of the rotating shaft 45 is fixedly connected to the sub-plate 7. A supporting frame 51 is welded to the side of the adjusting rod 23 away from the connecting frame 5. Two sliding frames 46 are fixedly installed on the upper end of the connecting frame 5. A positioning rack 49 is slidably connected to the inner wall of each sliding frame 46. A positioning wheel 50 is fixedly installed at one end of the positioning rack 49 close to the adjusting rod 23, and the positioning wheel 50 is slidably connected in the cavity of the supporting frame 51. Two racks 2 48 are fixedly installed on the upper end of the connecting frame 5, and each rack 2 48 is meshed with a gear 3 47 on the same side. A telescopic rod 52 is rotatably connected between the adjusting rod 23 and the connecting frame 5, and a buffer spring 53 is sleeved on the outer side wall of the telescopic rod 52.

[0039] Specifically, there is a gap between the adjusting rod 23 and the connecting frame 5. When the main board 6 is hit upward, the buffer spring 53 can be used to assist in buffering the device. When the cylinder 42 drives the rotating block 43 to extend and retract, the rotating rod 44 and the rotating shaft 45 can push the sub-plate 7 to rotate and bend on both sides of the main board 6. When the rotating block 43 moves in the direction of the main board 6, the tough plate 8 will be in a circular arc shape wrapped forward, which is suitable for a small number of people to watch, making the advertising effect more immersive. At the same time, when the rotating block 43 moves, the rack 2 48 will move, and the rack 2 48 will drive the gear 3 47 meshing with it to rotate. When the gear 3 47 rotates, it pushes the positioning rack 49 to move in the direction away from the main board 6. At this time, the positioning wheel 50 will slide in the cavity of the support frame 51. The elastic restoring force of the buffer spring 53 causes the connecting frame 5 to bend toward the ground around the rotating shaft 4, thereby driving the flexible screen 10 to tilt toward the ground, so that a small number of pedestrians can have a better viewing experience. Conversely, when the rotating block 43 moves in the direction away from the main board 6, the sub-board 7 will be pulled by the rotating rod 44 to bend toward the connecting frame 5, so that the flexible screen 10 presents a circular arc shape wrapped backwards. At the same time, with the movement of the rotating block 43, the positioning rack 49 moves toward the main board 6 through the transmission of the gear three 47, so that the connecting frame 5 is pulled by the positioning wheel 50 to fit with one side of the adjusting rod two 3, so that the connecting frame 5 is in a horizontal state, and the flexible screen 10 is also lifted when it is in a circular arc state, so that more people can watch the screen in crowded places.

[0040] The working principle and use process of the present invention are as follows: when the rotating block 43 is pushed to move by the cylinder 42 so that the rotating rod 44 stretches or pushes the sub-plate 7, the sub-plate 7 is rotated and bent on both sides of the main plate 6 by the tensile force of the rotating rod 44, so that the main plate 6 and the two sub-plates 7 continuously change their orientations, thereby adjusting the bending curvature and bending direction of the tough plate 8. At the same time, when the rotating block 43 moves, the rack 2 48 installed on the upper end of the rotating block 43 drives the gear 3 47 to rotate, and the gear 3 47 rotates and 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 generate corresponding rotation, lifting or lowering 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 toward the direction close to the connection frame 5, the rotating platform 11 starts to rotate, and when the resisting spring 16 rotates to the side away from the connection frame 5, as shown in FIG. Figure 3 As shown, the sliding block 14 is pushed by the resistance spring 16, so that the flexible belt 18 is pulled toward the rotating table 11, so that the tough plate 8 is fitted toward the main board 6, and then the display frame 9 and the flexible screen 10 are fitted to one side of the tough plate 8 through the limitation of the L-shaped positioning block 55 and the positioning rod 23. However, when the sub-plate 7 is bent in the direction away from the connecting frame 5, the rotating table 11 is rotated again, so that the resistance spring 16 is rotated to the side close to the connecting frame 5, as shown in FIG. Figure 5 As shown, at this time, the resistance spring 16 pushes the sliding block 14 so that the connecting rope 17 and the flexible belt 18 are no longer stretched straight, so that the flexible plate 8 has sufficient length to bend and will not be stretched into a straight plate. Then, the display frame 9 and the flexible screen 10 are fitted to one side of the flexible plate 8 through the limitation of the L-shaped positioning block 55 and the positioning rod 23;

[0042] Afterwards, the connecting plate 15 moves and drives the positioning plate 21 to move, and the positioning plate 21 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. The rack 40 slides and drives the meshing gear 2 39 on one side to rotate. When the gear 2 39 rotates, the auxiliary wheel 2 37 between the tough plate 8 and the sub-plate 7 starts to rotate. While the auxiliary wheel 2 37 rotates, it pulls the tough plate 8 to stretch to one side through friction and smoothes the tough plate 8.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
