Description

Technical Field

[0001] This utility model relates to the field of display screen design technology, specifically a splicing display screen. Background Technology

[0002] An LED display screen is a flat panel display composed of small LED module panels. Compared with other large-screen terminal displays, LED displays mainly have the advantages of high brightness, long lifespan, wide viewing angle, flexible screen size, easy computer interface, and rich software support.

[0003] An investigation revealed that Chinese utility model patent CN222167863U discloses a splicing LED display screen, including a screen. A fixing frame is fixedly connected to one side of the screen. A limiting structure is provided at one end of the fixing frame. The limiting structure includes four limiting blocks. The limiting blocks are fixedly connected to the fixing frame. A first circular hole is opened inside the limiting block. Slide rails are slidably connected to both sides of the limiting block. Second circular holes are opened at both ends of the slide rails. A fixing plate is fixedly connected to the surface of the slide rails. A plug rod is slidably connected inside the fixing plate. The arc surface of the plug rod is slidably connected to the first and second circular holes.

[0004] This splicing LED display screen uses a sliding rail, which is slidably connected to a limiting block on an adjacent LED display screen. Different LED display modules are spliced ​​together by using a rod to hold the limiting block within the sliding rail. However, for optimal viewing experience, the different modules of the LED display screen should be tightly connected. This splicing LED display screen, which manually slides the limiting block into the sliding rail, makes it difficult to achieve an interference fit between the limiting block and the sliding rail. If the limiting block is large, it is difficult to slide into the sliding rail; if the limiting block is small, it will cause the connection between adjacent displays to loosen. This loosening will become more severe after prolonged use, affecting the viewing experience.

[0005] Therefore, this utility model provides a splicing LED display screen to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides a splicing LED display screen, which aims to solve the problems mentioned in the background art, such as poor fit between the connecting components of existing LED display screens, which easily lead to assembly failure or loose assembly.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a splicing LED display screen, comprising a screen body, a fixing frame provided on the back edge of the screen body, a splicing mechanism provided on the fixing frame, the splicing mechanism including a connector that runs horizontally through the fixing frame, a threaded rod provided on the connector near the side of the adjacent fixing frame, and a rotating member fixedly provided on the end of the threaded rod away from the connector, the fixing frame having a splicing interface A that fits with the connector, the adjacent fixing frame having a splicing interface B that fits with the rotating member, the threaded rod being inserted into the fixing frame and threadedly connected to the fixing frame, a limiting plate being fixedly connected to the end of the connector away from the rotating member, the limiting plate being wider than the connector, the rotating member moving towards the connector during rotation, so that the rotating member and the limiting plate clamp the two fixed frames together, making the splicing firm, while the cross-sections of the connector and the rotating member are not circular, preventing the two screen bodies after splicing from rotating relative to each other.

[0010] Preferably, the width of the rotating component is greater than the width of the connecting component. When the screen body is in the disassembled state, the connecting component passes through the fixing frame and slides on the fixing frame. The rotating components and limiting plates at both ends of the connecting component can prevent the connecting component from detaching from the fixing frame, thereby preventing the loss of splicing mechanism components.

[0011] Preferably, the splicing mechanism further includes an I-shaped keel externally connected to the wall structure. The fixing frame located at the top and bottom of the screen body has splicing interfaces C that fit with the I-shaped keel. In order to prevent the spliced ​​LED display from lacking an external support structure and causing the overall stability to be insufficient, an I-shaped keel fixed to the external support structure is provided. By aligning the splicing interface C with the I-shaped keel, the top or bottom of the fixing frame is slidably connected to the I-shaped keel, thereby enhancing the overall stability of the LED display.

[0012] Preferably, a fixed crossbar is fixedly connected to the uppermost I-shaped keel, and side plates are fixedly provided at both ends of the fixed crossbar. A roller is rotatably connected between the two side plates, and a dustproof cloth is wrapped around the roller. After viewing, the roller can be rotated to lower the dustproof cloth, which covers the LED display screen to prevent dust accumulation.

[0013] Preferably, the bottom of the lowest screen body is provided with a support base, and a cleaning mechanism is provided between the fixed crossbar and the base. The cleaning mechanism includes a cleaning strip fixedly disposed at the end of the dustproof cloth, a sliding member fixedly disposed at both ends of the cleaning strip, a slide rail fixedly disposed at both ends on the fixed crossbar and the base respectively, a pull strap fixedly disposed at one end on the bottom of the sliding member, a bottom side plate fixedly disposed at both ends of the base, and a winding wheel rotatably connected to the bottom side plate. The end of the pull strap away from the sliding member is wound around the winding wheel. The cleaning strip abuts against the screen body, and the sliding member drives the cleaning strip to move downward to wipe away the dust on the screen body. When the dustproof cloth is retracted, the cleaning strip moves upward to clean the screen body.

[0014] (III) Beneficial Effects

[0015] This utility model incorporates a rotating component that rotates and is offset from the splicing interface B. The rotating component drives a threaded rod to rotate, and the threaded rod is threadedly connected to a connector. This causes the rotating component to move towards the connector during rotation, clamping the two assembled fixed frames together with the rotating component and the limiting plate, thus ensuring a secure splicing. At the same time, the cross-sections of the connector and the rotating component are not circular, preventing the two assembled screen bodies from rotating relative to each other.

[0016] This utility model features a cleaning strip, a rotating roller, and a winding wheel. The roller lowers the dustproof cloth, while the winding wheel drives a pulling belt. The pulling belt causes a sliding component to slide within a slide rail. The cleaning strip rests against the screen body, and the sliding component moves the cleaning strip downwards to wipe away dust from the screen body. When the dustproof cloth is retracted, the cleaning strip moves upwards to clean the screen body. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] This utility model provides a splicing LED display screen, see reference. Figures 1 to 4 The device includes a screen body 1, a mounting frame 11 on the back edge of the screen body 1, a splicing mechanism 2 on the mounting frame 11, a connector 21 extending horizontally through the mounting frame 11, a threaded rod 22 on the connector 21 near the adjacent mounting frame 11, and a rotating member 23 fixedly mounted on the end of the threaded rod 22 away from the connector 21. The mounting frame 11 has a splicing interface A12 that fits with the connector 21, and the adjacent mounting frame 11 has a splicing interface B13 that fits with the rotating member 23. The threaded rod 22 is inserted into the mounting frame 11 and threadedly connected to the mounting frame 11. A limiting plate 24 is fixedly connected to the end of the connector 21 away from the rotating member 23. The width of the limiting plate 24 is greater than the width of the connector 21.

[0027] When using this splicing LED display, bring the two screen bodies 1 that need to be spliced ​​close to each other. Pass the connector 21 through the splicing interface A12 through the fixing frame 11 on the back edge of the screen body 1. The rotating part 23 on the connector 21 is initially at the same angle as the connector 21. The rotating part 23 passes through the splicing interface B13 through the fixing frame 11 on the back of the adjacent screen body 1. The edge of the rotating part 23 is flush with the inner edge of the adjacent fixing frame 11. Rotate the rotating part 23 ninety degrees, and the rotating part 23 is offset from the splicing interface B13. The rotating part 23 drives the threaded rod 22 to rotate. The threaded rod 22 is threadedly connected to the connector 21, so that the rotating part 23 moves towards the connector 21 during rotation. This allows the rotating part 23 and the limiting plate 24 to clamp the two fixing frames 11 that are joined together, making the splicing firm. At the same time, the cross-sections of the connector 21 and the rotating part 23 are not circular to prevent the two screen bodies 1 after splicing from rotating relative to each other.

[0028] Furthermore, refer to Figures 1 to 2 The width of the rotating part 23 is greater than the width of the connecting part 21. When the screen body 1 is in the disassembled state, the connecting part 21 passes through the fixed frame 11 and slides on the fixed frame 11. The rotating part 23 and the limiting plate 24 at both ends of the connecting part 21 can prevent the connecting part 21 from falling off the fixed frame 11, thereby causing the loss of the splicing mechanism 2 components.

[0029] Furthermore, refer to Figures 5 to 6 The splicing mechanism 2 also includes an I-shaped keel 25 externally connected to the wall structure. The fixing frame 11 located at the top and bottom of the screen body 1 is provided with splicing interface C14 that fits with the I-shaped keel 25. In order to prevent the splicing LED display from lacking an external support structure and causing the whole to be unstable, an I-shaped keel 25 fixed to the external support structure is provided. The splicing interface C14 is aligned with the I-shaped keel 25, thereby slidingly connecting the top or bottom of the fixing frame 11 with the I-shaped keel 25, thereby enhancing the overall stability of the LED display.

[0030] It is worth noting that, referring to Figures 5 to 6 A fixed horizontal bar 3 is fixedly connected to the top I-shaped keel 25. Side plates 31 are fixedly installed at both ends of the fixed horizontal bar 3. A roller 32 is rotatably connected between the two side plates 31. A dustproof cloth 33 is wrapped around the roller 32. After watching, the roller 32 can be rotated to lower the dustproof cloth 33, which covers the LED display screen to prevent dust accumulation.

[0031] It should be noted that, referring to Figures 5 to 7 The bottom of the screen body 1 is provided with a base 4 for support. A cleaning mechanism 5 is provided between the fixed horizontal bar 3 and the base 4. The cleaning mechanism 5 includes a cleaning strip 51 fixedly installed at the end of the dustproof cloth 33, a sliding member 52 fixedly installed at both ends of the cleaning strip 51, a slide rail 53 fixedly installed at both ends of the fixed horizontal bar 3 and the base 4 respectively, a pull strap 54 fixedly installed at one end at the bottom of the sliding member 52, a bottom side plate 55 fixedly installed at both ends of the base 4, and a winding wheel 56 rotatably connected to the bottom side plate 55. The end of the pull strap 54 away from the sliding member 52 is wound around the winding wheel 56.

[0032] Televisions, computers and other electronic products have static electricity on their surfaces during use, making them prone to attracting dust. Therefore, even if the screen is covered with a dust cloth 33 after use, it still needs to be cleaned frequently. When the screen body 1 needs to be covered, the roller 32 and the winding wheel 56 are rotated. The roller 32 lowers the dust cloth 33, while the winding wheel 56 drives the pulling belt 54. The pulling belt 54 drives the sliding member 52 to slide in the slide rail 53. The cleaning strip 51 is pressed against the screen body 1, and the sliding member 52 drives the cleaning strip 51 to move downward to wipe away the dust on the screen body 1. When the dust cloth 33 is retracted, the cleaning strip 51 moves upward to clean the screen body 1.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
