[0002] LED displays are a new type of imaging electronic device made by arranging light-emitting diodes (LEDs) in sequence. LED unit boards, also known as LED display modules, are the core components of LED displays, consisting of LEDs, driver circuits, driver ICs, and plastic components. Their main function is to display images through control circuits, and they are widely used in indoor and outdoor display fields. LED unit boards are divided into two categories according to application scenarios: indoor surface-mount and outdoor modules. Outdoor and semi-outdoor module unit boards are characterized by high brightness and waterproofing; however, stable splicing of the LED display modules must be ensured during installation.

[0003] Regarding the stability of modular splicing of outdoor LED displays, structural stability is fundamental to ensuring stable display in complex environments. For example, LED displays installed on highways or in tunnels display road condition information or prompts. If a display malfunctions due to poor structural stability, it can have serious consequences. Improving the overall ease of installation, wiring, and maintenance of LED displays not only facilitates their deployment but also increases efficiency in troubleshooting. Therefore, based on these technical issues, we need to provide a modular splicing device for LED displays that offers stable structure, quick installation, and convenient maintenance.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, a further detailed description of this utility model will be provided below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] See Figures 1 to 6 As shown; This embodiment discloses a modular LED display splicing device, including LED display modules 1. Multiple LED display modules 1 are spliced ​​together and electrically connected to form an LED display. However, in order to ensure the stability of the spliced ​​LED display modules 1, we also need to optimize the stability of its splicing structure. Therefore, this modular LED display splicing device also includes: The horizontal splicing frame 2 is designed as a rectangular frame structure. Its overall length is determined according to the splicing length required for the LED display module 1. Multiple LED display modules 1 are spliced ​​sequentially along the extension direction of the horizontal splicing frame 2 to achieve splicing of multiple LED display modules 1 in one direction. The multiple horizontal splicing frames 2 are arranged parallel to each other and are fixedly connected by connectors between adjacent horizontal splicing frames 2 to splice multiple LED display modules 1 into a surface, thereby forming an overall LED display screen. Strip assembly opening 3: Strip assembly opening 3 is provided on both side frames of the horizontal splicing frame 2 along its extension direction to facilitate the subsequent installation of LED display module 1. The connecting bolt structure is set on the back plate of the LED display module 1 to connect with the strip assembly opening 3 of the horizontal splicing frame 2. In other words, the LED display module 1 is directly connected to the strip assembly opening 3 through the connecting bolt structure to complete the connection of the LED display module 1 on the horizontal splicing frame 2. Positioning block 4 is slidably disposed inside the strip assembly opening 3. Positioning block 4 is limited inside the strip assembly opening 3 by a connecting bolt structure. The installation of positioning block 4 and connecting bolt structure is synchronized. The connecting bolt structure fixes positioning block 4 inside the strip assembly opening 3. The stability of the support for LED display module 1 is maintained by the stability of the relative position formed by positioning block 4 inside the strip assembly opening 3, so as to avoid gaps and shaking. In addition, there are tightening bolts 5. Each end of the horizontal splicing frame 2 corresponding to the strip assembly opening 3 is threaded with a tightening bolt 5. The tightening bolt 5 is used to tighten onto the positioning block 4. After the LED display module 1 is assembled on the horizontal splicing frame 2, the tightening bolt 5 tightens onto the positioning block 4 corresponding to the LED display module 1 at both ends to finally fix the positioning block 4. This also allows the multiple LED display modules 1 to be arranged compactly, reducing gaps and preventing shaking. It also restricts the degree of freedom of the positioning block 4 in the direction of the tightening bolt 5, so that the positioning block 4 is completely fixed to ensure the stability of the overall structure after the LED display module 1 is installed.

[0018] Furthermore, the connector includes a connecting rod 6 and mounting plates 7 connected to both ends of the connecting rod 6. The two ends of the connecting rod 6 are perpendicular to each other with the two adjacent transverse splicing frames 2, and the mounting plates 7 are fixedly connected to the transverse splicing frames 2 by bolts.

[0019] The mounting plates 7 at both ends of the connecting rod 6 can be fixed to the connecting rod 6 by welding or bolting. The connecting rod 6 is then fixedly connected to the transverse splicing frame 2 to complete the connection between the transverse splicing frames 2.

[0020] Furthermore, multiple sets of connectors are provided between each adjacent horizontal splicing frame 2 to ensure the stability of the connection between adjacent horizontal splicing frames 2.

[0021] Furthermore, at least four sets of connecting bolt structures are provided on the LED display module 1 and are symmetrically distributed to correspond to the strip assembly openings 3 on the two side frames of the horizontal splicing frame 2. Taking four sets of connecting bolt structures as an example, two sets of connecting bolt structures are distributed on each side, and each pair of connecting bolt structures is connected to the strip assembly opening 3 on the corresponding side.

[0022] Furthermore, each set of connecting bolt structures includes two sets of connecting ears 8 and a set of fastening bolts 9, and the connecting ears 8 are provided with a first assembly hole 10 through which the fastening bolts 9 pass. Both sets of connecting ears 8 are vertically connected to the back plate of the LED display module 1, and the two sets of connecting ears 8 are respectively located on both sides of the strip assembly opening 3 on one side frame of the horizontal splicing frame 2. The fastening bolts 9 assembled in the first assembly hole 10 are also set through the strip assembly opening 3.

[0023] Specifically, during the assembly process, the LED display module 1 moves along the horizontal splicing frame 2, and the two sets of connecting ears 8 span both sides of one side frame of the horizontal splicing frame 2, which is equivalent to limiting the position on both sides of the frame. During subsequent installation, the fastening bolt 9 passing through the first assembly hole 10 also passes through the strip assembly opening 3 at the same time, and is then connected to the strip assembly opening 3 through the two sets of connecting ears 8 and the fastening bolt 9.

[0024] Furthermore, the positioning block 4 has a second assembly hole 11 through which the fastening bolt 9 passes; The positioning block 4 is a rectangular block that fits against the inner wall of the strip assembly opening 3 and slides within the strip assembly opening 3.

[0025] Here, the positioning block 4 is installed synchronously with the connecting bolt structure. After the LED display module 1 is moved into place on the horizontal splicing frame 2, the positioning block 4 is installed inside the strip-shaped assembly opening 3, and the positioning block 4 is positioned between the corresponding two sets of connecting ears 8. Therefore, after the two sets of connecting ears 8 are tightened by the fastening bolts 9, they will simultaneously fix the positioning block 4. At the same time, the positioning block 4 is a rectangular block, which can fit tightly against the inner wall of the strip-shaped assembly opening 3 to avoid shaking. Combined with the connecting bolt structure, the connection of the LED display module 1 on the horizontal splicing frame 2 is more stable, and the overall installation is simple and convenient, and subsequent disassembly and maintenance are convenient.

[0026] In addition, the overall frame structure of the horizontal splicing frame 2 and the simplified structure of the connecting bolt structure allow a large space on the back panel of the installed LED display module 1 to be open. This not only facilitates the heat dissipation of the LED display module 1, but also provides more space for wiring and other work after splicing the LED display module 1, greatly facilitating the subsequent splicing, installation, maintenance and repair of the LED display module 1.

[0027] Furthermore, by tightening the bolts 5 onto the positioning block 4, the multiple LED display modules 1 that are sequentially spliced ​​on the horizontal splicing frame 2 are pressed together to ensure the structural stability of the LED display modules 1 after splicing.

[0028] In the above technical solution, the modular splicing device for LED displays provided by this utility model has the following beneficial effects: The horizontal splicing frame of this utility model, combined with its connectors, forms a stable overall support structure for the LED display screen. The connecting bolt structure allows for simple and quick installation of the LED display screen modules, effectively improving installation efficiency and ensuring the overall splicing and installation of the LED display screen quickly, as well as ease of subsequent wiring and maintenance. This not only facilitates the layout of the LED display screen but also improves the efficiency of rapid troubleshooting. The positioning blocks, fixed inside the strip assembly opening, stabilize the structure and reduce gap movement. Furthermore, the tightening bolts tightly fix multiple LED display screen modules spliced ​​on the horizontal splicing frame, forming a stable modular splicing structure for the LED display screen. This effectively avoids display malfunctions caused by poor structural stability.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
