DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an LED exhibition display device and installation structure for a multi-story exhibition hall.

[0020] In a typical implementation of the present application, Figure 1-9 As shown, a LED exhibition display device and installation structure for a multi-layer exhibition hall includes: The exhibition equipment 1 comprises a spring steel frame 4, a plurality of flexible curtain blocks 5 are magnetically attracted to one side of the spring steel frame 4, a plurality of protrusions 6 are fixedly connected to one side of the spring steel frame 4, a threaded spring steel 7 is fixedly connected to one side of the spring steel frame 4, the threaded spring steel 7 is sandwiched between the spring steel frame 4 and the protrusion 6, a first frame 8 is fixedly connected to the left and right sides of the spring steel frame 4, a first shaft 9 is internally rotatably connected to the first frame 8, a first steel wire 10 is fixedly connected to the opposite side of the two first shafts 9, a second frame 11 is fixedly connected to the upper and lower sides of the spring steel frame 4, a second shaft 12 is internally rotatably connected to the second frame 11, a second steel wire 13 is fixedly connected to the opposite side of the two second shafts 12, and a driving structure 3 is arranged on one side of the spring steel frame 4, and the driving structure 3 is used to drive the deformation of the flexible screen; Two bending sensors are arranged inside the spring steel frame 4 in a vertically cross-arranged manner. A plurality of hydraulic pliers 14 are fixedly installed on one side of the spring steel frame 4 . The working ends of the plurality of hydraulic pliers 14 are arranged outside the first steel wire 10 and the second steel wire 13 .

[0021] By setting the above structure, any deformation of the exhibition equipment 1 can be achieved. Specifically, when the surface of the exhibition equipment 1 needs to be deformed, the middle part of the first steel wire 10 and the second steel wire 13 can be tightened to achieve the horizontal or vertical curling of the exhibition equipment 1. When the middle part of the first steel wire 10 or the second steel wire 13 is tightened, the two ends of the first steel wire 10 or the second steel wire 13 move toward the middle to drive the two first frames 8 or the two second frames 11 to move toward the middle. At this time, the spring steel frame 4 is bent as a whole, and the bending of the spring steel frame 4 drives the protrusion 6 to move. At the same time, the moving belt of the bending protrusion 6 of the spring steel frame 4 drives the threaded spring steel 7 to bend, and the bending of the spring steel frame 4 drives the bending of several flexible curtain blocks 5 to complete the deformation of the exhibition equipment 1. In the process of deformation of the exhibition equipment 1, the value of the bending sensor can be used to know how small the arc value generated by the deformation of the exhibition equipment 1 is, so that the curvature of the exhibition equipment 1 can be more accurately controlled. When the display device 1 needs to be deformed according to the preset wave-shaped curvature, the middle part of the first steel wire 10 or the second steel wire 13 is tightened, and the curvature on one side of the display device 1 reaches the preset deformation curvature of the display device 1. At this time, the hydraulic clamp 14 is started to fix the first steel wire 10 or the second steel wire 13 that reaches the preset value, and gradually fix it from both sides to the middle. After the fixing is completed, the middle part of the first steel wire 10 or the second steel wire 13 can be tightened or loosened to achieve the preset deformation curvature of the display device 1.

[0022] The driving structure 3 includes a telescopic sleeve 15 fixedly mounted on one side of the spring steel frame 4, a driving shell 16 is fixedly connected to the top of the telescopic sleeve 15, a driving motor 17 is fixedly mounted to the top of the inner wall of the driving shell 16, a driving shaft 18 is fixedly connected to the output end of the driving motor 17, a second roller 19 is rotatably connected to the outside of the driving shaft 18, a first roller 20 is rotatably connected to the bottom of the inner wall of the driving shell 16, the second steel wire 13 is wound around the outside of the second roller 19, and the first steel wire 10 is wound around the outside of the first roller 20; The second roller 19 is fixedly connected to the bottom with a second driving ring 21, the first roller 20 is fixedly connected to the top with a first driving ring 22, the driving shaft 18 is fixedly sleeved with an active driving ring 23 on the outside, the second driving ring 21, the first driving ring 22 and the active driving ring 23 are all provided with matching grooves on the outside, and the active driving ring 23 is slidably connected with a meshing ring 28 on the outside; The outside of the meshing ring 28 is rotatably connected to a rolling ring 29, and the outside of the rolling ring 29 is fixedly connected to two sliding plates 32. The inner wall of the drive shell 16 is fixedly connected to two mounting blocks 30, and the tops of the two mounting blocks 30 are fixedly installed with telescopic cylinders 31, and the output ends of the telescopic cylinders 31 are fixedly connected to the bottoms of the adjacent sliding plates 32.

[0023] By means of the above-mentioned structure, the second roller 19 or the first roller 20 can be driven to rotate. Specifically, when the exhibition equipment 1 needs to be driven to deform, the driving motor 17 is started, and the output end of the driving motor 17 rotates to drive the driving shaft 18 to rotate, and the driving shaft 18 rotates to drive the active driving ring 23 to rotate, and the active driving ring 23 rotates to drive the meshing ring 28 to rotate, and the meshing ring 28 rotates inside the rolling ring 29. At this time, when the second steel wire 13 needs to be tightened, the two telescopic cylinders 31 are started, and the extended ends of the two telescopic cylinders 31 move upward, and drive the corresponding The sliding plate 32 moves upward, and the two sliding plates 32 move upward to drive the rolling circle 29 to move upward, and the rolling circle 29 moves upward to drive the meshing circle 28 to move upward. At this time, the meshing circle 28 is meshed with the active driving circle 23 and the second driving circle 21 at the same time, thereby driving the second roller 19 to rotate to tighten the second steel wire 13. Similarly, when the first steel wire 10 needs to be tightened, the extended ends of the two telescopic cylinders 31 move downward, so that the first driving circle 22 and the active driving circle 23 are meshed with the meshing circle 28, so as to drive the first roller 20 to rotate to tighten the first steel wire 10.

[0024] Two limit forks 33 are clamped on the outside of the second drive circle 21 and the first drive circle 22, and four limit telescopic rods 25 are fixedly connected to the inner wall of the drive shell 16. The output ends of the four limit telescopic rods 25 are fixedly connected to the outside of the adjacent limit forks 33, and one side of the output end of the limit telescopic rod 25 is fixedly connected to the limit plate 26. Four electric telescopic rods 27 are fixedly installed on the inner wall of the drive shell 16, and the output ends of the four electric telescopic rods 27 are fixedly connected to one side of the adjacent limit plate 26.

[0025] By setting the above structure, the driven second roller 19 and the first roller 20 can be limited and fixed. Specifically, when the second roller 19 or the first roller 20 is driven to rotate, the electric telescopic rods 27 on both sides of the second roller 19 or the first roller 20 are started, and the extended ends of the electric telescopic rods 27 extend and drive the extended ends of the limiting telescopic rods 25 to extend. The extended ends of the limiting telescopic rods 25 extend and drive the limiting forks 33 to be stuck outside the second driving circle 21 or the first driving circle 22, thereby limiting the second roller 19 or the first roller 20.

[0026] The supporting mechanism 2 is used to support the exhibition equipment 1. The supporting mechanism 2 includes a base 34 placed on the ground. A telescopic column 36 is fixedly connected to the top of the base 34. The extended end of the telescopic column 36 is rotatably connected to a mounting head 37. The driving shell 16 is magnetically adsorbed on one side of the mounting head 37. A strain gauge is arranged inside the base 34. A track plate 42 is fixedly connected to the outside of the telescopic column 36. A track block 43 is connected to the outside of the track plate 42 in a damping sliding manner. The bottom of the track block 43 is rotatably connected to a third rotating plate 44. A pressure-absorbing telescopic rod 24 is fixedly installed on the bottom of the third rotating plate 44.

[0027] By setting the above structure, the exhibition equipment 1 can be stably supported. Specifically, when the exhibition equipment 1 is installed on the top of the supporting mechanism 2, the gravity of the exhibition equipment 1 is transmitted to the base 34, and the strain gauge inside the base 34 detects the stress deformation of the base 34. When it is detected that part of the base 34 is severely bent due to stress, the track block 43 inside the sliding track plate 42 is moved to the position where the base 34 is severely stressed. At this time, the third rotating plate 44 is rotated, and the pressure-absorbing telescopic rod 24 is started, so that the output end of the pressure-absorbing telescopic rod 24 is abutted against the ground, and the strain gauge inside the base 34 is used to detect the stress area and orientation of the adjusted base 34.

[0028] The bottom of the mounting head 37 is rotatably connected to the first rotating plate 38, the bottom of the first rotating plate 38 is fixedly installed with a rotating telescopic rod 39, one side of the extended end of the telescopic column 36 is fixedly connected to a rotating frame 40, the interior of the rotating frame 40 is rotatably connected to the second rotating plate 41, and the output end of the rotating telescopic rod 39 is fixedly connected to one side of the second rotating plate 41.

[0029] By means of the above-mentioned structure, the exhibition equipment 1 can be driven to rotate up and down. Specifically, when the exhibition equipment 1 needs to be rotated up and down, the rotating telescopic rod 39 is started, and the output end of the rotating telescopic rod 39 is extended. At this time, the first rotating plate 38 rotates inside the mounting head 37, and at the same time, the second rotating plate 41 rotates inside the rotating frame 40, and exerts force between the telescopic column 36 and the mounting head 37, so that the mounting head 37 rotates. The rotation of the mounting head 37 drives the exhibition equipment 1 to rotate, thereby adjusting the direction of the exhibition equipment 1.

[0030] An extension plate 35 is slidably connected inside the base 34 to further improve the stability of the exhibition device 1 .

[0031] The working principle of the present invention is as follows: when the surface of the exhibition equipment 1 needs to be deformed, the drive motor 17 is started, the output end of the drive motor 17 rotates to drive the drive shaft 18 to rotate, the drive shaft 18 rotates to drive the active drive ring 23 to rotate, the active drive ring 23 rotates to drive the meshing ring 28 to rotate, and the meshing ring 28 rotates inside the rolling ring 29. At this time, when the second steel wire 13 needs to be tightened, the two telescopic cylinders 31 are started, the extended ends of the two telescopic cylinders 31 move upward, and drive the corresponding sliding plates 32 to move upward, and the two The sliding plate 32 moves upward to drive the rolling ring 29 to move upward, and the rolling ring 29 moves upward to drive the meshing ring 28 to move upward. At this time, the meshing ring 28 is meshed with the active driving ring 23 and the second driving ring 21 at the same time, thereby driving the second roller 19 to rotate to tighten the second steel wire 13. Similarly, when the first steel wire 10 needs to be tightened, the extended ends of the two telescopic cylinders 31 move downward, so that the first driving ring 22 and the active driving ring 23 are meshed with the meshing ring 28, so as to drive the first roller 20 to rotate to tighten the first steel wire 10. When the middle part of the first steel wire 10 or the second steel wire 13 is tightened, the two ends of the first steel wire 10 or the second steel wire 13 move toward the middle, driving the two first frames 8 or the two second frames 11 to move toward the middle. At this time, the spring steel frame 4 is bent as a whole, and the bending of the spring steel frame 4 drives the protrusion 6 to move. At the same time, the bending of the protrusion 6 of the spring steel frame 4 drives the threaded spring steel 7 to bend, and the bending of the spring steel frame 4 drives the bending of several flexible curtain blocks 5 to complete the deformation of the exhibition equipment 1. In the process of deformation of the exhibition equipment 1, the value of the bending sensor can be used to know how small the arc value generated by the deformation of the exhibition equipment 1 is, so that the curvature of the exhibition equipment 1 can be controlled more accurately. When the exhibition equipment 1 needs to be deformed according to the preset wave-shaped curvature, the middle part of the first steel wire 10 or the second steel wire 13 is tightened, and the curvature of one side of the exhibition equipment 1 reaches the preset deformation curvature of the exhibition equipment 1. At this time, the hydraulic clamp 14 is started to fix the first steel wire 10 or the second steel wire 13 that reaches the preset value, and gradually fix it from both sides to the middle. After the fixing is completed, the middle part of the first steel wire 10 or the second steel wire 13 can be tightened or loosened to achieve the preset deformation curvature of the exhibition equipment 1; When the exhibition equipment 1 is adjusted, the electric telescopic rods 27 on both sides of the second roller 19 or the first roller 20 are started, and the extended ends of the electric telescopic rods 27 extend and drive the extended ends of the limiting telescopic rods 25 to extend, and the extended ends of the limiting telescopic rods 25 extend and drive the limiting forks 33 to be stuck outside the second driving circle 21 or the first driving circle 22, thereby limiting the second roller 19 or the first roller 20; When the exhibition equipment 1 needs to be rotated up and down after adjustment, the rotating telescopic rod 39 is started, and the output end of the rotating telescopic rod 39 is extended. At this time, the first rotating plate 38 rotates inside the mounting head 37, and the second rotating plate 41 rotates inside the rotating frame 40, and exerts force between the telescopic column 36 and the mounting head 37, so that the mounting head 37 rotates. The rotation of the mounting head 37 drives the exhibition equipment 1 to rotate, thereby adjusting the direction of the exhibition equipment 1; When the exhibition equipment 1 needs to be installed on the top of the supporting mechanism 2, the gravity of the exhibition equipment 1 is transmitted to the base 34, and the strain gauge inside the base 34 detects the stress deformation of the base 34. When it is detected that part of the base 34 is severely bent due to stress, the track block 43 inside the sliding track plate 42 is moved to the position where the base 34 is severely stressed. At this time, the third rotating plate 44 is rotated and the pressure-relieving telescopic rod 24 is started, the output end of the pressure-relieving telescopic rod 24 is abutted against the ground, and the strain gauge inside the base 34 is used to detect the stress area and orientation of the adjusted base 34.
