Technical Field
[0001] This utility model relates to the field of display equipment technology, specifically a split-type LED screen. Background Technology
[0002] As a core device for visual display, LED screens are widely used in venue displays, outdoor advertising, conference centers, and other scenarios. Existing split-type LED screens typically employ a single-motor, single-side drive design, using simple guide rails to achieve screen sliding. The screen is directly fixed to the mounting bracket with bolts. This design is simple and has low manufacturing costs, making it suitable for some applications in small-to-medium-sized display scenarios.
[0003] However, the existing structure has shortcomings: the single-motor, single-side drive method makes it difficult to achieve synchronous linkage between the two screens; the simple guide rail has limited guiding accuracy, which can easily lead to problems such as inconsistent running speeds on both sides and sliding jamming during the opening and closing of the screen. In severe cases, it can also cause collisions at the edges of the screen and positional displacement, affecting the display effect and the service life of the equipment. In addition, the installation method of directly fixing the screen with bolts means that subsequent disassembly and maintenance require the bolts to be removed one by one, which is cumbersome and time-consuming, greatly reducing maintenance efficiency and failing to meet the actual needs of efficient operation and maintenance. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a split-type LED screen to solve the problems mentioned in the background section. This invention features a novel structure. By incorporating a gear and rack drive mechanism and a roller guide groove structure, a single motor drive enables synchronous linkage between the two screens. High-precision guidance enhances movement stability, preventing slippage, jamming, and edge collisions, ensuring display quality and extending equipment lifespan. Furthermore, a press-type snap-fit mechanism allows for quick fixing and unlocking of the screen without bolts, overcoming the cumbersome disassembly and assembly issues of traditional bolt-fixed systems, improving maintenance efficiency, and meeting the needs of efficient operation and maintenance.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] Please refer to Figures 1 to 8 This utility model provides a technical solution: a split-type LED screen, including an L-shaped frame 1, two mounting frames 2 on the rear side of the L-shaped frame 1, a driving mechanism 3 on the upper rear side of the L-shaped frame 1, sliding frames 4 slidably fitted on the inner walls of the two mounting frames 2, LED screen bodies 5 slidably fitted on the inner walls of the sliding frames 4, rectangular grooves 6 on one side of the inner walls of the two mounting frames 2, and snap-fit mechanisms 7 that cooperate with the sliding frames 4 on the inner walls of the two rectangular grooves 6, roller guide grooves 8 on the upper side of the L-shaped frame 1 below the two mounting frames 2, multiple guide wheels 9 on the lower side of the two mounting frames 2, and multiple guide wheels 9 slidably fitted on the inner walls of the roller guide grooves 8, and a display groove 10 that cooperates with the two LED screen bodies 5 at the center of the L-shaped frame 1. During operation, the LED screen body 5 is assembled in the sliding frame 4. The sliding frame 4 and the mounting frame 2 slide together to achieve initial positioning. The locking mechanism 7 can limit and fix the sliding frame 4. The driving mechanism 3 drives the two mounting frames 2 to move. The guide wheel 9 on the lower side of the mounting frame 2 slides along the roller guide groove 8 of the L-shaped frame 1 to ensure that the mounting frame 2 moves smoothly. When the mounting frame 2 drives the LED screen body 5 to the display slot 10 in the center of the L-shaped frame 1, the display preparation is completed. This process realizes the stable assembly and movement guidance of the screen body, avoids screen body deviation, ensures accurate display position, and lays the structural foundation for subsequent opening and closing actions.
[0027] In this embodiment, the drive mechanism 3 includes a protective shell 31 fixedly connected to the rear side of the L-shaped frame 1. A drive motor 32 is mounted on one side of the protective shell 31, and a gear shaft 33 is fixedly connected to the output end of the drive motor 32. A guide rail 34 is fixedly connected to one side of the L-shaped frame 1. Slides 35 are fixedly connected to the upper sides of both mounting frames 2. A lower rack 36 and an upper rack 37 are respectively mounted on the upper sides of the two slides 35. One end of the gear shaft 33 is rotatably engaged with one side of the L-shaped frame 1, and the lower rack 36 and the upper rack 37 mesh with the upper and lower sides of the gear shaft 33 respectively. Both slides 35 are slidably engaged on the guide rail 34. The driving process is as follows: the drive motor 32 starts and drives the gear shaft 33 to rotate. Since the lower rack 36 and the upper rack 37 are respectively meshed on the upper and lower sides of the gear shaft 33, the rotation of the gear shaft 33 can synchronously drive the two slides 35 to slide in opposite or the same direction along the guide rail 34, thereby driving the two mounting frames 2 to open and close synchronously. Through the single motor drive and the meshing transmission of the gear and rack, the synchronous linkage of the two mounting frames 2 is realized. The cooperation between the guide rail 34 and the slides 35 improves the stability of movement, avoids running jams, ensures the smooth opening and closing process of the screen, and improves the reliability of equipment operation.
[0028] In this embodiment, the snap-fit mechanism 7 includes a fixed plate 71 fixedly connected to one side of the inner wall of the rectangular groove 6. A triangular guide plate 72 is fixedly connected to one side of the fixed plate 71. A mating guide plate 73 that cooperates with the triangular guide plate 72 is fixedly connected to one side of the fixed plate 71. An L-shaped guide groove 74 is provided on the side of the triangular guide plate 72 near the mating guide plate 73. An initial guide groove 75 that cooperates with the L-shaped guide groove 74 is provided above one side of the mating guide plate 73. An final guide groove 76 that cooperates with the triangular guide plate 72 is provided below one side of the mating guide plate 73. A rotating plate 77 is rotatably fitted on one side of the sliding frame 4. A torsion spring 78 is provided at the rotation point of the rotating plate 77 and the sliding frame 4. A guide wheel 79 is rotatably fitted at one end of the rotating plate 77. The two ends of the torsion spring 78 are fixedly connected to one side of the sliding frame 4 and the pivot of the rotating plate 77, respectively. The guide wheel 79 abuts against the inclined surface of the triangular guide plate 72. A channel is formed between the triangular guide plate 72 and the mating guide plate 73 for the guide wheel 79 to slide through. During assembly, the sliding frame 4 is pressed down to slide along the mounting frame 2. The guide wheel 79 on one side of the sliding frame 4 abuts against the inclined surface of the triangular guide plate 72. The torsion spring 78 provides elastic buffering and reset force. The guide wheel 79 slides upward along the L-shaped guide groove 74 of the triangular guide plate 72. After transitioning through the initial guide groove 75 of the cooperating guide plate 73, it is embedded into the inner wall of the L-shaped guide groove 74, completing the pressing and fixing. When unlocking, the sliding frame 4 is pressed down again. Under the elastic reset force of the torsion spring 78, the guide wheel 79 enters the final guide groove 76. Under the guidance of the final guide groove 76 and the inclined surface of the lower side of the triangular guide plate 72, the unlocking is achieved. The pressing structure enables the sliding frame 4 to be quickly fixed and unlocked without bolts or additional tools, making the operation convenient. The cooperation between the torsion spring 78 and the guide wheel 79 ensures that the pressing action is smooth and without jamming, and the locking state is stable. At the same time, it simplifies the disassembly and assembly process during screen maintenance and greatly improves maintenance efficiency.
[0029] In this embodiment, the upper side of the sliding frame 4 is provided with a through slot 11, and the inner wall of the through slot 11 is magnetically fitted with a connecting plate 12. The lower end of the connecting plate 12 extends through into the interior of the sliding frame 4. The upper side of the LED screen body 5 is provided with a connecting slot 13 that mates with the connecting end of the connecting plate 12. Two dovetail grooves 14 are provided on one side of the inner wall of the mounting frame 2. Two dovetail blocks 15 are fixedly connected to the side of the sliding frame 4 near the inner wall of the mounting frame 2. The dovetail blocks 15 are slidably fitted on the inner wall of the dovetail grooves 14. Two spring push plates 16 are installed on one side of the inner wall of the mounting frame 2. The movable ends of the two spring push plates 16 are elastically abutting against one side of the sliding frame 4. After the LED screen body 5 slides into the sliding bracket 4, the insertion plate 12 is inserted into the insertion slot 11, and its lower end is engaged with the insertion slot 13 of the LED screen body 5. The magnetic attraction enhances the stability of the engagement. The sliding bracket 4 slides along the dovetail groove 14 of the mounting frame 2 via the dovetail block 15. The spring push plate 16 elastically abuts against the sliding bracket 4. The dovetail structure ensures the sliding of the sliding bracket 4 is accurate. The spring push plate 16 can buffer the sliding impact and provide disassembly and reset force. The insertion plate 12 realizes the quick fixing and disassembly of the LED screen body 5, improves the assembly accuracy and stability of the screen, and further simplifies the disassembly and assembly of the LED screen body 5, reducing the difficulty of maintenance.
[0030] When using the device, first fix the LED screen body 5 to the sliding frame 4 through the plug-in card plate 12. Press the sliding frame 4 so that it slides into the mounting frame 2 through the dovetail structure. The locking mechanism 7 follows the memory card logic to press and fix the sliding frame 4. Start the drive motor 32 to drive the gear shaft 33 to rotate. Drive the two slides 35 to slide in opposite / same directions along the guide rail 34 through the meshing racks on the upper and lower sides. The mounting frame 2 moves with the slides 35. Its lower guide wheel 9 slides along the roller guide groove 8 to ensure stability. When it moves to the display slot 10, the LED screen body 5 unfolds / folds to complete the display switch. During maintenance, press the sliding frame 4 again to unlock the locking mechanism 7. The spring push plate 16 assists in pushing out the sliding frame 4. The screen body can be taken out by removing the plug-in card plate 12. The whole system realizes the synchronous opening and closing of the screen body, stable assembly and rapid maintenance through the coordinated transmission, guidance and locking structure, which improves the reliability of operation and maintenance efficiency.
