Description

Technical Field

[0001] The utility model relates to the technical field of LED splicing screens, in particular to a large-screen LED splicing screen. Background Art

[0002] Large-screen LED splicing technology combines multiple LED display modules to create a continuous, unified, large-scale display interface. LED splicing screens can be customized to various sizes and shapes, adapting to various installation environments and usage requirements. They provide excellent visual effects for both indoor and outdoor use. Large-screen LED splicing screens are widely used in commercial advertising, live sports events, concerts, conference rooms, surveillance centers, and other applications, favored for their high brightness, wide viewing angles, and reliability.

[0003] After searching, the Chinese utility model patent with publication number: CN220290400U discloses a seamless splicing LED display screen, including a mounting frame and an LED display screen body, and the LED display screen body is fixedly installed on the wall through the mounting frame. The LED display screen body includes multiple closely adjacent display screen modules, and a mounting frame is fixedly provided on the rear end face of the LED display screen body. A first magnetic positioning member and a second magnetic positioning member are respectively fixedly provided on the adjacent two end sides of the mounting frame. The connection and fixation of two adjacent groups of display screen modules are achieved by the opposite attraction characteristics of the first magnetic positioning member and the second magnetic positioning member.

[0004] In the above technical solution, the LED display module is fixed to the frame by magnetic fixation. However, after long-term use, the magnetic fixation may cause slight deformation of the structure of the four corners of the splicing screen due to physical factors such as gravity and changes in ambient temperature. This will cause the originally flat screen to become uneven and the gap to become larger, affecting the connection strength and the viewing experience of the LED screen. Utility Model Content

[0005] The purpose of the present invention is to provide a large-screen LED splicing screen to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A large-screen LED splicing screen, comprising: an outer frame, an LED display module and a vertical support rod, a vertical support rod is provided between the upper and lower inner walls of the outer frame, magnetic columns are provided at the four corners of the LED display module, an L-shaped bracket is provided on the outside of the vertical support rod, a threaded rod is provided inside the L-shaped bracket, a guide column is provided on the outer wall of the vertical support rod on one side of the magnetic column, an L-shaped bottom plate is provided on the outside of the guide column, a top plate is provided at one end of the L-shaped bottom plate, connecting plates are provided on both sides of the top plate, a magnetic conductive sheet is provided on one side of the connecting plate, a fixed block is provided on the inner side of the top plate, and a conical adjustment block is provided on the outer wall of the threaded rod on the outside of the fixed block.

[0007] Furthermore, one end of the magnetic column is cylindrical and the other end is truncated. One end of the truncated cone of the magnetic column is magnetically adsorbed to the magnetic conductive sheet. A C-shaped bracket is provided on one side of the connecting plate, and the C-shaped bracket is stuck on the outer side of the cylindrical magnetic column.

[0008] Furthermore, a guide hole is provided inside the L-shaped bottom plate and outside the guide column, and a limit block is provided on the top of the guide column, and the diameter of the limit block is larger than the diameter of the guide hole.

[0009] Furthermore, a threaded hole matching the threaded rod is provided inside the L-shaped bracket.

[0010] Furthermore, a transverse support rod is provided between the vertical support rods, and retreat grooves are provided at both ends of the threaded rods on the upper and lower sides of the outer frame, and the retreat grooves are used to facilitate personnel to rotate the threaded rods.

[0011] Furthermore, the C-shaped bracket is made of elastic steel plate, and both ends of the threaded rod are provided with hexagonal nut heads.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model realizes that when a large-screen LED assembly screen is used, the magnetic column and the magnetic conductive sheet are magnetically attracted to each other, and the magnetic column and the magnetic conductive sheet are positioned until the cylindrical portion of the magnetic column is engaged with the C-shaped bracket. At this time, the magnetic column and the magnetic conductive sheet are attracted and fixed, and the magnetic attraction between the magnetic column and the magnetic conductive sheet and the engagement of the C-shaped bracket ensures a stable connection of the LED display module.

[0014] The magnetic conductive sheet and the C-shaped bracket generate pulling force on the magnetic column, so that the magnetic column always tends to move to one side, pressing the four corners of the LED display module tightly against the vertical support rod, ensuring the flatness of the LED display module. At the same time, by magnetically absorbing the pulling force, the four corners of the LED display module can be prevented from warping and deforming outward, ensuring the long-term flatness of the entire spliced screen, which is conducive to improving the seamless display effect of the spliced screen.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-Figure 4The utility model provides a technical solution: a large-screen LED splicing screen, comprising: an outer frame 1, an LED display module 2 and a vertical support rod 3, a vertical support rod 3 is provided between the upper and lower inner walls of the outer frame 1, a magnetic column 13 is provided at the four corners of the LED display module 2, an L-shaped bracket 5 is provided on the outside of the vertical support rod 3, a threaded rod 6 is provided inside the L-shaped bracket 5, a guide column 9 is provided on the outer wall of the vertical support rod 3 on one side of the magnetic column 13, an L-shaped bottom plate 10 is provided on the outside of the guide column 9, a top plate 11 is provided at one end of the L-shaped bottom plate 10, connecting plates 12 are provided on both sides of the top plate 11, a magnetic conductive sheet 14 is provided on one side of the connecting plate 12, a fixing block 8 is provided on the inside of the top plate 11, and a frustum-shaped adjusting block 7 is provided on the outer wall of the threaded rod 6 on the outside of the fixing block 8. The magnetic attraction between the magnetic column 13 and the magnetic conductive sheet 14 is combined with the clamping of the C-shaped bracket 15 to ensure the stable connection of the LED display module. The magnetic conductive sheet 14 and the C-shaped bracket 15 generate a pulling force on the magnetic column 13, so that the magnetic column 13 always has a tendency to move to one side, and the four corners of the LED display module 2 are tightly pressed against the vertical support rod 3, ensuring the flatness of the splicing of the LED display module 2. At the same time, the tension exerted on the magnetic column 13 can prevent the four corners of the LED display module 2 from warping and deforming outward, ensuring the long-term flatness of the overall splicing screen, which is conducive to improving the seamless display effect of the splicing screen.

[0022] One end of the magnetic column 13 is cylindrical and the other end is truncated. One end of the truncated cone of the magnetic column 13 is magnetically adsorbed with the magnetic conductive sheet 14. A C-shaped bracket 15 is provided on one side of the connecting plate 12. The C-shaped bracket 15 is stuck on the outer side of the cylindrical magnetic column 13. Through the cooperation of the C-shaped bracket 15 of the magnetic column 13, the connection stability of the LED display module 2 is improved. At the same time, the C-shaped bracket 15 can subsequently generate a thrust on the truncated cone of the magnetic column 13, so that the magnetic column 13 is subjected to force, and the LED display module 2 is tightly pressed against the vertical support rod 3. Through the support of the vertical support rod 3, the LED display module 2 can be prevented from deforming inward. At the same time, through the tensile force of the magnetic column 13, the four corners of the LED display module 2 can also be prevented from warping and deforming outward, thereby improving the overall flatness of the spliced screen.

[0023] A guide hole is provided inside the L-shaped bottom plate 10 on the outside of the guide column 9, and a limit block is provided at the top of the guide column 9. The diameter of the limit block is larger than the diameter of the guide hole. When the fixed block 8 generates a thrust on the top plate 11, the guidance of the guide column 9 can make the top plate 11 move only to the side away from the vertical support rod 3 instead of tilting, thereby guiding the movement direction of the top plate 11 and its components.

[0024] The L-shaped brackets 5 have threaded holes inside that mate with the threaded rods 6. Transverse support rods 4 are positioned between the vertical support rods 3 to enhance the frame's stability. The outer frame 1 has recessed slots at both ends of the threaded rods 6 on the upper and lower sides, each with a hexagonal nut head. These recessed slots and hexagonal nut heads facilitate rotation of the threaded rods 6. To secure the threaded rods 6 after rotation, locking nuts can be installed on the outside of the threaded rods 6. These locking nuts abut against the two L-shaped brackets 5 near the outer frame 1, preventing the threaded rods 6 from rotating on their own.

[0025] The C-shaped bracket 15 is made of elastic steel plate. The elastic steel plate material can ensure that when the truncated cone end of the magnetic column 13 is pressed, the C-shaped bracket 15 can produce elastic deformation, so that the opening becomes larger, which is convenient for the truncated cone of the magnetic column 13 to pass through. In addition, after the truncated cone of the magnetic column 13 passes through, the opening of the C-shaped bracket 15 can shrink by itself and be stuck on the outside of the cylindrical part of the magnetic column 13, so as to facilitate the subsequent pulling force on the magnetic column 13.

[0026] When the assembled screen of large-screen LED is used, the vertical support rods 3 and the horizontal support rods are welded according to the size of the LED display module 2 to ensure that the two side plates of the LED display module 2 can overlap with the vertical support rods 3 without interfering with the magnetic column 13. When the LED display module 2 is installed, it is positioned by the magnetic attraction of the magnetic column 13 and the magnetic conductive sheet 14, and then the LED display module 2 is pressed so that one end of the truncated cone of the magnetic column 13 can expand the C-shaped bracket 15, causing the C-shaped bracket 15 to produce elastic deformation and the opening to become larger until the cylindrical part of the magnetic column 13 is snapped with the C-shaped bracket 15. At this time, the magnetic column 13 and the magnetic conductive sheet 14 are adsorbed and fixed. The magnetic attraction of the magnetic column 13 and the magnetic conductive sheet 14 cooperates with the snapping of the C-shaped bracket 15 to ensure the stable connection of the LED display module.

[0027] After that, the top plate 11, the connecting plate 12, the magnetic sheet 14 and the C-shaped bracket 15 are moved together to the side away from the vertical support rod 3, thereby generating a pulling force on the magnetic column 13 through the magnetic sheet 14 and the C-shaped bracket 15, so that the magnetic column 13 always has a tendency to move to one side, pressing the four corners of the LED display module 2 tightly against the vertical support rod 3, ensuring the flatness of the LED display module 2. At the same time, the pulling force applied to the magnetic hold 13 can prevent the four corners of the LED display module 2 from warping and deforming outward, ensuring the long-term flatness of the overall splicing screen, which is conducive to improving the seamless display effect of the splicing screen.

[0028] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
