Description

Technical Field

[0001] The utility model relates to the technical field of LED screen equipment, and more specifically to a splicing device for an ultra-clear LED large screen. Background Art

[0002] With the continuous development of electronic technology, LED large-screen image display has been widely used. The ultra-large screen and clear and realistic display effect it brings have greatly improved the work quality in the fields of monitoring, security, conference, simulation, etc. Due to the size limitation of a single screen itself, in order to achieve ultra-large screen display, it is necessary to splice multiple screens together to form a large screen. For traditional display modules, when any one of the display modules is damaged, it is necessary to remove the installation box from the inside when disassembling it. In this way, for the large-screen display screen when wall-mounted, it is necessary to remove it from the wall as a whole before the damaged display module can be repaired and replaced. This box installation method is not convenient for later disassembly and maintenance, and it is also not convenient for early installation, which increases the labor intensity of workers and takes a long time to install. In view of this, the inventor proposes a splicing device for ultra-clear LED large screens to solve this problem. By setting a splicable installation frame, the LED module can be quickly spliced ​​and installed, and can be quickly disassembled for maintenance when a fault occurs.

[0003] In order to realize the rapid installation of LED modules and facilitate disassembly during maintenance, a Chinese patent (authorization announcement number: CN220748717U) discloses a spliced ​​combined LED screen. The utility model includes a frame, and the inner wall of the frame is fixedly connected with a plurality of vertical beams along its length direction. The frame is arranged in a matrix with a plurality of LED screens, and a plurality of bolts are penetrated on the LED screens. The outer wall of the vertical beam is provided with threaded holes matching with the bolts at the corresponding positions of the bolts, and the outer wall of the bolt between the LED screen and the vertical beam is fixedly sleeved with a positioning ring; the utility model connects the bolts with the corresponding threaded holes, and the LED screen can be fixed on the inner side of the frame. When a certain LED screen fails and needs to be disassembled, it is only necessary to rotate the bolts in the opposite direction until the bolts are completely out of the threaded holes, and then pull the bolts outward, so that the positioning ring can be pressed against the rear side of the LED screen. By continuing to pull the bolts, the positioning ring can be used to bring the LED screen out to the outside of the frame, thereby realizing the disassembly of the LED screen, and the operation is simple and convenient.

[0004] This solution still has some shortcomings in application. Since the size of LED screen splicing is often adjusted according to demand, the frame needs to be able to be quickly spliced ​​and increased or decreased according to demand, otherwise it cannot meet the actual use needs. In addition, after the overall splicing frame is installed on the wall, the fixing device will be covered by the wall, which is not convenient for the disassembly of the bolt fixing structure, resulting in difficulty in disassembly. Therefore, it is necessary to improve the structure of the LED screen splicing device so that it can be quickly spliced ​​according to the use requirements, and can be quickly disassembled when maintenance is required, so as to improve the practicality of the LED screen splicing device.
