Technical Field

[0001] This utility model belongs to the field of display splicing technology, and in particular relates to a splicing display connection structure. Background Technology

[0002] A spliced ​​electronic display screen is a display screen composed of multiple display units, usually referring to an LCD splicing screen. This type of display screen uses liquid crystal displays and has features such as splicability, durability, and ultra-narrow bezels.

[0003] Currently, splicing displays requires a large number of bolts for fixing. The bolts need to be connected while the display is being stabilized, which is a slow process and prone to deviations, affecting the splicing quality.

[0004] To address the aforementioned issues, this application proposes a modular display screen connection structure. Utility Model Content

[0005] The purpose of this utility model is to provide a modular display screen connection structure that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a modular display screen connection structure, including a frame and display modules spliced ​​inside it;

[0008] The connecting frame, located on the back of the display module, is a scaled-down "U"-shaped structure. The plates that make up the "U"-shaped structure of the connecting frame extend outward from the corners of the connecting frame to form a support.

[0009] The two brackets at the corner of the connecting frame are respectively slidably installed with a first clamping plate and a second clamping plate inside. The first clamping plate and the second clamping plate move outward and inward synchronously. The first clamping plate has a blocking part fixed on the side adjacent to the second clamping plate, which abuts against the tail end of the second clamping plate.

[0010] The inner side of the frame has a slot that aligns with the bracket.

[0011] Preferably, the bracket for mounting plate one has a limiting groove inside, which extends inward through the corner area of ​​the connecting frame, and the limiting groove inside the bracket for mounting plate two extends to the corner of the connecting frame.

[0012] Preferably, a sliding groove is provided above the closed end of the limiting groove of the mounting plate one, and a push block is fixed above the tail end of the mounting plate one, passing through the sliding groove and located on the outside of the connecting frame.

[0013] Preferably, a side groove is provided in the middle section of the card plate one adjacent to the card plate two, for receiving the tail end of the card plate two during recycling.

[0014] Preferably, the tail end side of the second card plate is provided with a guide edge that abuts against the outer edge of the rear end face of the side groove.

[0015] Preferably, the second card plate has side plates extending from both sides, passing through through slots opened on both sides of the bracket, and a support plate extending outward from the rear edge of the through slot for installing the elastic pull-back part and connecting it to the side plate.

[0016] Preferably, the upper part of the connecting frame has an clearance groove in the same direction as the limiting groove of the mounting plate one, and a partition is formed between the clearance groove and the limiting groove. A screw is installed in the partition for pushing the mounting plate one outward.

[0017] This utility model has the following beneficial effects:

[0018] 1. By utilizing the coordinated entry and exit of the first and second card plates, a pre-connection is formed with the card slot or limiting slot, thereby pre-fixing and supporting individual display modules. This facilitates fine-tuning of the position after all display modules are spliced, helps to reduce the gap between adjacent display modules, and improves the splicing quality.

[0019] 2. By utilizing the pre-fixed support effect of the display modules, a single display module can be disassembled during maintenance without affecting the structural stability of adjacent display modules. This reduces the difficulty of the work, shortens the maintenance time, and helps to quickly repair faulty display modules and restore their operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] A modular display screen connection structure is used to splice multiple display modules 2 on an overall flat panel display device. The structure utilizes a first card plate 331 and a second card plate 332 to pre-connect with adjacent mechanisms, forming a pre-fixed support effect for the display modules 2. This facilitates fine-tuning of the positions after all display modules 2 are temporarily assembled, helps improve the splicing accuracy of adjacent display modules 2, and reduces the gaps in the flat panel display device.

[0034] In some embodiments, the modular display screen connection structure is specifically as follows: Figure 1 As shown in Figure 3, it includes frame 1 and display module 2;

[0035] Multiple display modules 2 are spliced ​​together to form a single flat-panel display screen, which is installed inside the frame 1.

[0036] The connecting frame 3 is located on the back of the frame 1 and is a "U"-shaped structure with the edges of the frame 1 scaled down proportionally.

[0037] Among them, each corner of the connecting frame 3 has a bracket 31 extending outward, and two brackets 31 are a set of perpendicularly intersecting;

[0038] Furthermore, the two brackets 31 are respectively slidably installed with a first clamping plate 331 and a second clamping plate 332, which move outward and inward synchronously;

[0039] Cardboard 1 331 and Cardboard 2 332 are a set, and there are two sets in total. They are distributed in two sets of brackets 31 that are diagonally far apart from each other in the display module 2.

[0040] It is understandable that by opening a slot 101 in the inner wall of the frame 1 and aligning it with the bracket 31, a snap-fit ​​can be formed when the first card plate 331 and the second card plate 332 extend outward, thus pre-fixing the display module 2.

[0041] Furthermore, by setting each set of card plate 331 and card plate 332 in the same position on the back of each display module 2, after adjacent display modules 2 are connected, the bracket 31 on the back of the display module 2 can be connected to the card plate 331 and card plate 332 to form a pre-fixed connection for the display module 2.

[0042] like Figure 4 As shown in Figure 5, a limiting groove 3101 is provided inside the bracket 31. The limiting groove 3101 for installing the second card plate 332 extends inward to the corner area of ​​the connecting frame 3, and the limiting groove 3101 for installing the first card plate 331 passes through the corner and continues to extend inward.

[0043] Among them, a sliding groove 3102 is provided above the closed end of the limiting groove 3101 used to install the card plate 331, which extends upward through the connecting frame 3 and to the corner area at the open end.

[0044] Furthermore, the connecting frame 3 has an opening-top clearance groove 32 inside, which extends from the middle area of ​​the side plate of the connecting frame 3 toward the slide groove 3102. The connecting frame 3 between the clearance groove 32 and the slide groove 3102 forms a partition.

[0045] A screw 34 is spirally installed inside the partition plate to push the clamping plate 331 to move outward.

[0046] like Figure 5 As shown in Figure 6, a side groove 3311 is provided on the side of the card plate 331 adjacent to the card plate 332, and the end of the card plate 332 near the card plate 331 has a chamfer to form a smooth guide edge 3323, which is located on the side edge adjacent to the clearance groove 32.

[0047] Among them, the bracket 31 used to install the second card plate 332 has through slots on both sides of its side walls near the outlet end, and the two sides of the second card plate 332 extend out of the second card plate 332 and pass through the through slots.

[0048] Furthermore, the end edge of the through groove away from the opening of the bracket 31 extends outward from the support plate 311, and an elastic pull-back part 3322 is fixedly installed between it and the side plate 3321;

[0049] It is understandable that when the first card plate 331 and the second card plate 332 are in the storage state, one end of the second card plate 332 is located inside the side groove 3311, and the guide edge 3323 abuts against the rear edge of the side groove 3311.

[0050] When the first card plate 331 moves outward, the rear edge of the side groove 3311 applies a pushing force to the second card plate 332 through the guide edge 3323, causing the second card plate 332 and the first card plate 331 to slide outward simultaneously.

[0051] When the first card plate 331 is retracted, the stretched elastic pull-back part 3322 resets and drives the second card plate 332 to retract, so that one end of the guide edge 3323 enters the interior of the side groove 3311.

[0052] like Figure 6 As shown, a blocking part 3312, made of silicone rubber, is fixed to the rear end of the first card plate 331 on the side adjacent to the second card plate 332. When the second card plate 332 abuts against the blocking part 3312, frictional resistance is applied to prevent vibration and slippage.

[0053] In some publicly available information, the specific usage methods of the modular display screen connection structure are as follows:

[0054] S1. Starting from the bottom corner of frame 1, place display module 2 inside frame 1;

[0055] S2. Move the first card plate 331 outwards and apply an oblique pushing force to the guide edge 3323 using the rear end face of the side groove 3311, so that the second card plate 332 can slide outwards synchronously until it is engaged in the inside of the card groove 101.

[0056] S3. Place another display module 2 in the same direction on one side of the pre-fixed display module 2, and move the first card plate 331 so that it and the second card plate 332 slide outward into the back of the pre-fixed display module 2 at the same time, until they are engaged with the limiting groove 3101 opened in the support 31 on the back of the display module 2.

[0057] S4. After the horizontal display module 2 is installed, install the display modules 2 horizontally again starting from the side of the frame 1.

[0058] S5. The middle layer display module 2 is inserted from top to bottom, so that the limiting groove 3101 directly engages with the pre-fixed display module 2 with the card plate 331 and card plate 332 extending outward from the back.

[0059] S6. When installing the top layer display module 2, reverse the back of the display module 2 pre-fixed in the lower adjacent layer, and push the first card plate 331 located in the upper area to retract it and the second card plate 332. At this time, the display module 2 can be pushed horizontally between the display module 2 and the inner wall of the frame 1. Then, push the first card plate 331 located in the upper area on the back of the lower adjacent layer display module 2. Finally, push the first card plate 331 on the back of the top layer display module 2 to connect and fix it.

[0060] S7. When installing the second and subsequent display modules 2 horizontally on the top layer, the same principle applies as in S6. Move the card plate 331 that is closest to the back of the adjacent display module 2 in the opposite direction, insert the display module 2, and then move the card plate 331 to reset to form the final snap-fit.

[0061] S8. When inspecting a single display module 2, the single display module 2 can be removed by reversing the card plate 331 on the back of the adjacent display module 2 to release its fixation.
