Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1

[0030] To solve the problem of easy damage to the display screen 41 during maintenance, please refer to Figure 1-Figure 5, a polyhedron LED display screen splicing device provided in this embodiment can expand and close the display screen 41 in the display assembly 4 through the pushing assembly 3, so that it is convenient to maintain and replace components such as the control card and the connector after it is expanded, and there is no need to disassemble and assemble the display screen 41 back and forth, thereby reducing the risk of damage to the display screen 41 and improving the safety of the display screen 41 during maintenance. The device includes a base 1, and the base 1 is used to carry a support assembly 2 and a display assembly 4. A support assembly 2 is provided on the base 1, and the support assembly 2 is used to connect the display assembly 4. The support assembly 2 is provided with a display assembly 4 and a pushing assembly 3 for pushing the display assembly 4. A rotating assembly 5 for driving the pushing assembly 3 to rotate is provided in the base 1. A limit assembly 6 for limiting the rotation of the rotating assembly 5 is provided in the base 1. When using the display component 4 for the first time, connect the support component 2 and the base 1, and install the display component 4 on the pushing component 3. When maintaining the parts of the display component 4, the pushing component 3 is driven by rotating the rotating component 5 to unfold the display component 4, and then its parts are maintained. After maintenance, the pushing component 3 is driven by the rotating component 5 to close the display component 4, so that there is no need to disassemble and assemble the display screen 41 in the display component 4 back and forth, thereby reducing the risk of damage to the display screen 41 and improving the safety of the display screen 41 during maintenance.

[0031] When the display assembly 4 is maintained, the display screen 41 needs to be disassembled and assembled back and forth, which makes it easy to damage the display screen 41 during maintenance, causing the display screen 41 to be unable to continue to be used normally, affecting the display effect and work efficiency. The pushing assembly 3 includes a cross-shaped support block 31 arranged on the support assembly 2, and the support block 31 is installed on the support disk 24. Four T-shaped sliding blocks 32 are slidably connected in the support block 31, and the sliding blocks 32 are used to connect the display screen 41. A rotating disk 33 installed on the support assembly 2 is provided above the support block 31, and the rotating disk 33 is used to drive the sliding blocks 32 to slide. Four rotating grooves 34 are provided on the rotating disk 33, and the rotating grooves 34 are used to connect to the connecting blocks 35. The connecting blocks 35 arranged in the rotating grooves 34 are fixedly connected to the sliding blocks 32. The display assembly 4 includes six display screens 41 arranged around a cube, and the six display screens 41 are installed around to form a cube, and its control card, connectors and other components are arranged inside the surrounding. A connecting plate 42 is fixedly connected to the display screen 41, and a plurality of first bolts 7 are threadedly connected to the connecting plate 42, wherein four display screens 41 are connected to the sliding block 32 by the first bolts 7, and the upper and lower display screens 41 are connected to the support plate 24 by the first bolts 7. When the parts of the display assembly 4 are maintained, the rotating disk 33 is driven to rotate by the rotating assembly 5, and the sliding block 32 is driven by the rotating groove 34 when the rotating disk 33 rotates, so that the sliding block 32 slides in the support block 31, and the four display screens 41 are driven to unfold by the sliding of the sliding block 32, and then the parts in the display assembly 4 are conveniently maintained after unfolding, and the rotating assembly 5 is operated in the opposite way after maintenance to close the display assembly 4, so that it is not necessary to disassemble and assemble the display screen 41 in the display assembly 4 back and forth during maintenance, thereby reducing the risk of damage to the display screen 41 and improving the safety of the display screen 41 during maintenance.

[0032] Considering that the display assembly 4 needs to be supported to improve its stability, see Figure 1-Figure 5 The support assembly 2 includes a chassis 21 adapted to the base 1, and the chassis 21 is used to connect the support rod 22 to the base 1. A plurality of second bolts 71 are threadedly connected between the base 1 and the chassis 21, and the second bolts 71 are used to facilitate the disassembly and assembly of the base 1 and the chassis 21. The chassis 21 is fixedly connected with the support rod 22, and the end of the support rod 22 is fixedly connected with the support plate 24, and the support rod 22 is used to carry the support plate 24, and the support plate 24 is used to carry the pushing assembly 3. The support rod 22 is rotatably connected with the rotating rod 23, and the rotating plate 33 is installed on the top of the rotating rod 23, and the bottom of the rotating rod 23 is rotatably installed in the base 1, and the rotating rod 23 is used to connect and drive the rotating plate 33. The chassis 21 and the base 1 are connected by the second bolts 71, and the support rod 22 supports the support plate 24, and the connection between the support plate 24 and the pushing assembly 3 realizes that the support rod 22 supports the pushing assembly 3 and the display assembly 4.

[0033] Considering that the sliding block 32 needs to drive the display screen 41 to open and close, thereby reducing the need to disassemble and assemble the display screen 41 during maintenance, refer to Figure 1-Figure 5 The chassis 21 is provided with a placement groove 211, and the rotating assembly 5 includes a hexagonal rotating block 51 rotating in the placement groove 211. The hexagonal rotating block 51 can be rotated with the help of an electric pistol drill to facilitate the rotation of the rotating block 51. The end of the rotating block 51 is fixedly connected with a rotating shaft 52 rotating in the base 1, and the rotating shaft 52 is used to carry a first gear 53. The rotating shaft 52 is fixedly connected with a first gear 53, and the first gear 53 is meshedly connected with a second gear 54 installed on the rotating rod 23. By rotating the rotating block 51, the rotating shaft 52 drives the first gear 53 to rotate, and the first gear 53 drives the second gear 54 to rotate, thereby driving the rotating rod 23 to drive the rotating disk 33 to rotate, thereby realizing the expansion and closing of the display screen 41, and improving the safety of the display screen 41 during maintenance.

[0034] Considering that the rotating assembly 5 is prone to instability when driving the display screen 41 to unfold and close, causing shaking and affecting the stability of the display screen 41, refer to Figure 1-Figure 5 Therefore, the limiting assembly 6 includes a fixed block 61 and a support plate 62 fixed on the inner wall of the base 1, and the fixed block 61 and the support plate 62 are used to support the sliding rod 63. The sliding rod 63 is slidably connected in the fixed block 61 and the support plate 62, and the sliding rod 63 is used to connect the clamping block 65. The end of the sliding rod 63 is fixedly connected with a clamping block 65 adapted to the second gear 54, and the clamping block 65 is used to limit the second gear 54. The sliding rod 63 is sleeved with a first spring 64 installed on the support plate 62 and the clamping block 65, and the first spring 64 is used to limit the movement of the clamping block 65. When the first gear 53 drives the second gear 54 to rotate, the elastic force of the first spring 64 causes the block 65 to break away from the restriction on the second gear 54 and be driven to retract by the sliding rod 63. After the display screen 41 is unfolded and closed, the rotating block 51 stops rotating, and the elastic force of the first spring 64 causes the block 65 to rebound to the groove between the second gears 54 and restrict the second gear 54, so that the display screen 41 can be firmly fixed when it is unfolded and closed, thereby reducing the shaking of the display screen 41 and improving the safety of the display screen 41 when in use.

[0035] Example 2

[0036] Based on the first embodiment, considering that the display screen 41 needs to be ventilated when it is closed to improve the heat dissipation, refer to Figure 1-Figure 5Therefore, a plurality of lower air holes 221 are provided at the lower end of the support rod 22, and a plurality of upper air holes 222 are provided at the upper end of the support rod 22. The upper air holes 222 are arranged in the closed space of the display screen 41 when the display screen 41 is closed. When the display screen 41 is closed, the external air enters the upper air holes 222 through the lower air holes 221, and the air in the closed space of the display screen 41 is discharged from the lower air holes 221 through the upper air holes 222. Then, the closed space of the display screen 41 is ventilated, and the heat generated when the display assembly 4 is used is ventilated and cooled, thereby improving the normal use effect of the display assembly 4.

[0037] Considering that the display screen 41 is not airtight when closed and affects the display effect, refer to Figure 1-Figure 5 Therefore, the four ends of the display screen 41 are provided with inclined surfaces 43, and the four end inclined surfaces 43 are mutually matched. When the display screen 41 is closed, the edges between the display screens 41 can be closed to a minimum through the inclined surfaces 43 at the edges, thereby improving the display effect of the display screen 41.
