Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a splicing curved LED display screen. Background Technology

[0002] Currently, LED displays, as commonly used flat panel displays, are composed of several small LED module panels. Their core component, LED (light-emitting diode), achieves display functions by controlling the light emission of semiconductors. These diodes are made of compounds of gallium (Ga) and arsenic (As), phosphorus (P), nitrogen (N), and indium (In). When electrons and holes recombine, they can radiate visible light, and different materials correspond to different light emission colors—gallium arsenide phosphide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and indium gallium nitride diodes emit blue light. With their diverse light emission characteristics, LED displays are widely used to display text, images, videos, and other information, playing an important role in advertising, public information dissemination, stage performances, and other fields.

[0003] To meet the needs of specific scenarios, curved LED displays have emerged. Chinese patent with announcement number "CN207651108U" discloses a representative structure, which includes a curved LED display body, a fixing frame, a support rod, a brush, and a stepper motor. The device connects the back of the display to the support rod through the fixing frame. The brush is vertically set on the surface of the display and its top is driven by the stepper motor through the upper crossbar. The stepper motor drives the brush to move on the surface of the screen, which can achieve efficient dust removal and cleaning, effectively improve the display clarity, and provide convenience for the daily maintenance of curved displays, solving the problem of high cleaning difficulty to a certain extent.

[0004] However, existing curved LED displays still have significant drawbacks:

[0005] Firstly, most curved LED displays are designed as a single unit, which, due to the limitations of their curved structure, cannot be flexibly assembled to extend or shorten them according to actual size requirements, resulting in poor adaptability to different scenarios. Secondly, if a large-size display is required, directly purchasing a single-unit screen will significantly increase costs and burden the economy. Thirdly, the single-unit structure means that damage to a part will render the entire display unusable, leading to high repair costs and interruption of normal display operation. It is evident that existing curved LED displays have shortcomings in structural design and practical application, and urgently require technological improvements to optimize performance. Utility Model Content

[0006] To address the aforementioned problems, this utility model proposes a splicing curved LED display screen to more accurately resolve the problems described above.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model proposes a splicing arc-shaped LED display screen, including a support ring. A cross mounting bracket is fixedly installed on the inner side of the support ring. A telescopic rod is fixedly installed at the top center of the cross mounting bracket. A top plate is fixedly installed on the top of the telescopic rod. Support rods are fixedly installed at equal intervals in a ring on the top of the top plate. A sleeve is fitted on the top of the support rod. A connecting plate is fixedly installed on the outer side of the sleeve. A bearing plate is fixedly installed on the outer surface of the support rod at the bottom of the sleeve. The top of the bearing plate and the bottom of the sleeve are fitted together. A splicing mechanism is fixedly installed on the outer end of the connecting plate. An arc-shaped display screen is installed on the outer end of the connecting plate through the splicing mechanism. Each arc-shaped display screen is spliced ​​and installed with each other through the splicing mechanism.

[0009] The assembly mechanism includes an assembly module and a fixing plate. The assembly module is fixedly installed on the inner side of the arc-shaped display screen, and the fixing plate is fixedly installed on the outer end of the connecting plate. Both the upper and lower ends of the connecting plate are fixedly installed with snap-fit ​​modules, and the connecting plate is snapped together with the assembly module through the snap-fit ​​modules.

[0010] Furthermore, the assembly module includes an assembly rail and an assembly strip. The assembly rail is fixedly installed at both ends of the side of the curved display screen near the connecting plate. The assembly strip is fixedly installed on both sides of the side of the fixing plate near the curved display screen. The assembly strip is inserted into the interior of the assembly rail. The internal cavity of the assembly rail has a convex shape when viewed from above. The overall cross-sectional shape of the assembly strip is also convex.

[0011] Furthermore, the snap-fit ​​module includes a guide rail and a snap-fit ​​limiting frame. The guide rail is fixedly installed at the upper and lower ends of the fixed plate. Limiting springs are fixedly installed at both ends of the guide rail. Movable blocks are fixedly installed on the outer side of the limiting springs. Locking pins are fixedly installed on the outer side of the movable blocks. The snap-fit ​​limiting frame is fixedly installed at the four corners of the curved display screen near the connecting plate. The end of the locking pin passes through the guide rail and is inserted into the interior of the snap-fit ​​limiting frame.

[0012] Furthermore, the snap-fit ​​module also includes a detachable push-armrest frame, the two ends of which are respectively connected to the side of the fixed plate away from the curved display screen of two movable blocks, and the outer surface corners of the detachable push-armrest frame are all set to be arc-shaped.

[0013] Furthermore, the telescopic rod includes a main sleeve, which is fixedly installed at the top center of the cross mounting bracket. A sliding rod is slidably connected inside the main sleeve, and the top of the sliding rod is fixedly connected to the bottom of the top plate. A mounting screw is threadedly connected to the upper end of one side of the main sleeve, and the end of the mounting screw passes through the main sleeve.

[0014] Furthermore, the internal cavity of the main sleeve is convex in top view, and the overall top view of the slide rod is also convex in top view. Limiting holes are linearly arranged at equal intervals on one side of the slide rod. The end of the mounting screw penetrates the main sleeve and is inserted into a corresponding limiting hole. The mounting screw is a hand-tightening screw.

[0015] Furthermore, each of the outer ends of the cross-shaped mounting bracket is fixedly mounted with a mounting plate, and the mounting plate has a mounting hole in the middle, which is a countersunk hole.

[0016] The beneficial effects of this utility model are:

[0017] 1. During the application of this technical solution, the number of curved displays can be flexibly increased or decreased according to the actual display size requirements during use by setting up an assembly mechanism, so as to extend or shorten the overall length of the display. Unlike existing technologies, it does not rely on fixed-size integrated screens. At the same time, it does not require the direct purchase of expensive large-size integrated screens. It can meet the size requirements of different scenarios by splicing small-size curved displays, which greatly reduces the raw material loss in the production stage, the investment in special equipment in the transportation stage, and the labor costs in the installation stage. In this way, it achieves the effect of improving the adaptability of the display screen to the scene and controlling the overall usage cost, and solves the problems of the inability to flexibly adjust the size of curved LED displays and the high purchase and use costs of large-size screens in existing technologies.

[0018] 2. During the application of this technical solution, by setting up an assembly mechanism in conjunction with relevant disassembly and assembly structures, if a certain arc-shaped display screen is damaged during use, it is not necessary to disassemble the entire display device. Only a simple operation is required to quickly remove the damaged screen and replace it with a new screen. Unlike existing technologies, the entire display screen will not be shut down due to a partial failure. At the same time, the repair process does not require complicated testing and disassembly procedures, which shortens the repair time. Moreover, only a single damaged screen needs to be replaced, avoiding the waste of resources caused by the overall scrapping. This achieves the effect of improving the convenience of repair and ensuring the continuity of display operation, and solves the problems of partial damage to arc-shaped LED display screens leading to overall failure, as well as the high difficulty and cost of repair in existing technologies.

[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] Example 1

[0027] A splicing curved LED display screen includes a support ring 1, a cross mounting bracket 2 fixedly installed on the inner side of the support ring 1, a telescopic rod 3 fixedly installed at the top center of the cross mounting bracket 2, a top plate 4 fixedly installed on the top of the telescopic rod 3, support rods 5 fixedly installed at equal intervals in a ring on the top of the top plate 4, a sleeve 7 sleeved on the top of the support rod 5, a connecting plate 8 fixedly installed on the outer side of the sleeve 7, a bearing plate 9 fixedly installed on the outer surface of the support rod 5 at the bottom of the sleeve 7, the top of the bearing plate 9 and the bottom of the sleeve 7 being fitted together, an assembly mechanism 6 fixedly installed on the outer end of the connecting plate 8, and a curved display screen 10 installed on the outer end of the connecting plate 8 through the assembly mechanism 6, and the curved display screens 10 being spliced ​​together with each other through the assembly mechanism 6;

[0028] The assembly mechanism 6 includes an assembly module 63 and a fixing plate 62. The assembly module 63 is fixedly installed on the inner side of the curved display screen 10, and the fixing plate 62 is fixedly installed on the outer end of the connecting plate 8. Both the upper and lower ends of the connecting plate 8 are fixedly installed with snap-fit ​​modules 61. The connecting plate 8 is snapped into the assembly module 63 via the snap-fit ​​modules 61. During application, the device provides overall foundation support through the support ring 1, and the cross mounting bracket 2 provides installation support for the telescopic rod 3, allowing the telescopic rod 3 to adjust its length during use, thereby adjusting the height of the top plate 4 to meet the installation height requirements of the curved display screen 10 in different scenarios. The support rod 5 at the top of the top plate 4 is used to mount the sleeve 7, and the bearing plate 9 supports the sleeve 7, preventing it from sliding down the support rod 5. The connecting plate 8 on the outer side of the sleeve 7... The assembly mechanism 6 connects to the curved display screen 10. The assembly module 63 in the assembly mechanism 6 cooperates with the fixing plate 62. With the help of the snap-fit ​​modules 61 at the upper and lower ends of the connecting plate 8, the connecting plate 8 and the assembly module 63 can be stably snapped together. At the same time, the curved display screens 10 can also be spliced ​​together by the assembly mechanism 6 to form curved display surfaces of different sizes as needed. This design allows the number of curved display screens 10 to be flexibly increased or decreased according to actual needs, without relying on an integrated screen body. It is convenient to adjust according to the display size requirements and can be handled individually when a single curved display screen 10 has a problem, without the need for overall replacement. This improves the flexibility and convenience of use and solves the problems of the existing integrated curved LED display screens, such as the inability to flexibly adjust the size and high maintenance costs.

[0029] Combination Figures 2-5 As shown, the assembly module 63 includes an assembly rail 631 and an assembly strip 632. The assembly rail 631 is fixedly installed on both ends of the side of the curved display screen 10 near the connecting plate 8. The assembly strip 632 is fixedly installed on both sides of the side of the fixing plate 62 near the curved display screen 10. The assembly strip 632 is inserted into the interior of the assembly rail 631. The internal cavity of the assembly rail 631 has a U-shaped shape when viewed from above. The overall cross-sectional shape of the assembly strip 632 is also U-shaped. The snap-fit ​​module 61 includes a guide rail 611 and a snap-fit ​​limiting frame 612. The guide rail 611 is fixedly installed on the upper and lower ends of the fixing plate 62. Both ends of the guide rail 611 are fixedly installed inside. A limit spring 613 is installed, and a movable block 614 is fixedly installed on the outside of the limit spring 613. A locking pin 615 is fixedly installed on the outside of the movable block 614. A locking limit frame 612 is fixedly installed at the four corners of the side of the arc-shaped display screen 10 near the connecting plate 8. The end of the locking pin 615 passes through the guide rail 611 and is inserted into the inside of the locking limit frame 612. The locking module 61 also includes a disassembly and assembly push armrest 616. The two ends of the disassembly and assembly push armrest 616 are respectively connected to the side of the two movable blocks 614 on the fixed plate 62 away from the arc-shaped display screen 10. The outer surface corners of the disassembly and assembly push armrest 616 are all set to be arc-shaped.

[0030] In the above-described embodiments of this application, during the application of this device, by setting up the assembly module 63 and the snap-fit ​​module 61, the connection and disassembly of the curved display screen 10 and the connecting plate 8 can be smoothly realized during use. The assembly rail 631 and the assembly strip 632 in the assembly module 63 have a convex cross-section because the internal cavity of the assembly rail 631 and the overall cross-section of the assembly strip 632 are both convex. When the assembly strip 632 is inserted into the assembly rail 631, it can form a tight and non-detachable fit, allowing the curved display screen 10 and the connecting plate 8 to complete the initial stable docking. The guide rail 611 of the snap-fit ​​module 61 is equipped with a limit spring 613. The limit spring 613 will move the movable block 614 and the snap pin 615 on the outside of the movable block 614. When it is necessary to fix it, the end of the snap pin 615 can pass through the guide rail 611 and insert into the snap-fit ​​limit frame 6. In step 12, the structure after initial docking is further secured to prevent the curved display screen 10 from becoming loose during use. If it is necessary to disassemble or replace the screen, push the disassembly and assembly push armrest 616, which will move the two movable blocks 614. The movable blocks 614 will then pull out of the locking limit frame 612 with the locking pins 615. Disassembly and assembly can be completed without complicated tools. Moreover, the outer surface of the disassembly and assembly push armrest 616 is rounded, which will not cut the hands during operation and can protect the safety of the operator. This design not only makes the connection between the curved display screen 10 and the connecting plate 8 sufficiently stable and ensures the reliability during use, but also makes subsequent disassembly and maintenance simple and convenient, and avoids safety hazards during operation. It well meets the needs of connection stability, disassembly and assembly convenience and operation safety in actual use.

[0031] Example 2

[0032] Combination Figures 1-3 As shown, the telescopic rod 3 includes a main sleeve 31, which is fixedly installed in the middle of the top of the cross mounting bracket 2. A sliding rod 32 is slidably connected inside the main sleeve 31. The top of the sliding rod 32 is fixedly connected to the bottom of the top plate 4. A mounting screw 33 is threadedly connected to the upper end of one side of the main sleeve 31. The end of the mounting screw 33 passes through the main sleeve 31. The internal cavity of the main sleeve 31 is convex in shape when viewed from above. The overall shape of the sliding rod 32 is also convex in shape when viewed from above. Limiting holes 34 are linearly arranged at equal intervals on one side of the sliding rod 32. The end of the mounting screw 33 passes through the main sleeve 31 and is inserted into a corresponding limiting hole 34. The mounting screw 33 is a hand-tightening screw. Mounting plates 11 are fixedly installed on the outer ends of the cross mounting bracket 2. Mounting holes 12 are provided in the middle of the mounting plates 11. The mounting holes 12 are countersunk holes.

[0033] In the above-described embodiments of this application, during the application of this device, by setting the telescopic rod 3's main sleeve 31, slide rod 32, and hand-tightening mounting screw 33, as well as the mounting plate 11 at the outer end of the cross mounting bracket 2, the height of the top plate 4 can be flexibly adjusted and the entire device can be firmly fixed during use. The slide rod 32 can slide inside the main sleeve 31. Since the internal cavity of the main sleeve 31 and the overall top view shape of the slide rod 32 are both convex, this shape can prevent the slide rod 32 from rotating when sliding, ensuring the stability of height adjustment. When the slide rod 32 slides to the target height, the mounting screw 33 at the upper end of one side of the main sleeve 31 is rotated, so that the end of the screw passes through the main sleeve 31 and is inserted into the corresponding limiting hole 34 on one side of the slide rod 32. The sliding rod 32 can be fixed to the main sleeve 31, thereby locking the height of the top plate 4. The mounting plate 11 at the outer end of the cross mounting bracket 2 has a mounting hole 12 in the middle, and the mounting hole 12 is a countersunk hole. When the device is fixed in the preset position by passing a bolt through the mounting hole 12, the bolt head can be embedded in the countersunk hole and will not protrude from the surface of the mounting plate 11. This design can accurately adjust the height of the top plate 4 according to actual needs and adapt to different installation scenarios. The convex structure can also ensure the stability during height adjustment. The hand-tightening mounting screw 33 can be operated without additional tools, which improves the convenience of adjustment. The countersunk hole can avoid the safety hazards caused by the bolt head protruding. At the same time, it makes the appearance of the device more regular after installation, ensuring safety and practicality during use.

[0034] The working principle and advantages of this utility model are as follows: First, the basic fixing operation of the device is carried out. The support ring 1 serves as the bottom basic component. The cross mounting bracket 2 on its inner side can connect the support ring 1 and the telescopic rod 3. When the bolt passes through the mounting hole 12 in the middle of the mounting plate 11 at the outer end of the cross mounting bracket 2, the bolt head can be embedded in the mounting hole 12, thereby achieving a stable connection between the entire device and the mounting surface and preventing the device from shifting during use.

[0035] After the basic fixing is completed, the height of the device is adjusted to adapt to the scene requirements. The main sleeve 31 of the telescopic rod 3 is fixed on the top of the cross mounting bracket 2. The sliding rod 32 is pushed to slide inside the main sleeve 31. When the sliding rod 32 drives the top plate 4 to move to the required height, the mounting screw 33 on one side of the main sleeve 31 is rotated so that the end of the mounting screw 33 is inserted into the limiting hole 34 of the sliding rod 32, thereby restricting the sliding of the sliding rod 32 and fixing the height of the top plate 4. Then, the support rod 5, sleeve 7 and connecting plate 8 are assembled. The support rod 5 on the top of the top plate 4 can support the sleeve 7. The bearing plate 9 on the outside of the support rod 5 can support the sleeve 7. The sleeve 7 is sleeved on the top of the support rod 5 and fits against the bearing plate 9, so that the position of the connecting plate 8 on the outside of the sleeve 7 is stable, providing a connection base for the subsequent installation of the arc display screen 10.

[0036] Next, the installation of a single curved display screen 10 is carried out. The fixing plate 62 at the outer end of the connecting plate 8 is used to connect the assembly module 63. When the assembly rail 631 on the inner side of the curved display screen 10 is aligned with the assembly strip 632 on the fixing plate 62, pushing the curved display screen 10 will allow the assembly strip 632 to be inserted into the assembly rail 631. At this time, the disassembly and assembly push armrest 616 is pressed. The disassembly and assembly push armrest 616 will drive the movable block 614 to move inward to the guide rail 611. The movable block 614 compresses the limit spring 613 while pulling the locking pin 615 inward. When the assembly strip 632 is fully inserted into the assembly module 63, the assembly module 63 is fully installed. After the rail 631 is released, the disassembly and assembly push armrest 616 is released, the limit spring 613 returns to its deformation and pushes the movable block 614 outward. The movable block 614 drives the locking pin 615 to pass through the guide rail 611 and insert into the locking limit frame 612 of the arc-shaped display screen 10, thereby completing the fixing of a single arc-shaped display screen 10. If multiple arc-shaped display screens 10 need to be spliced, simply align the splicing strips 632 of the adjacent display screens with the splicing rail 631 and insert them, and then fix them through the locking module 61. This will allow the overall length of the display screen to be adjusted, and increasing or decreasing the number of display screens can meet different size requirements.

[0037] This technical solution effectively addresses the shortcomings of existing curved LED displays. By cooperating the assembly rails 631 and assembly bars 632 of the assembly mechanism 6, and engaging the locking pins 615 and locking limit frames 612, the curved display screens 10 can be flexibly assembled without the need for a single-piece design, thus meeting the needs of size adjustment in different scenarios. Furthermore, it eliminates the need to purchase large-size screens as a whole, reducing production, transportation, and installation costs through the assembly of smaller screens. When a curved display screen 10 is damaged, the damaged screen can be disassembled and replaced simply by pushing the disassembly and assembly push handle 616, without requiring the entire device to be shut down, reducing maintenance costs and downtime. In addition, the cooperation between the support ring 1 and the cross mounting bracket 2 enhances the overall stability of the device, the structural design of the telescopic rod 3 facilitates height adjustment, and the rounded edges of the disassembly and assembly push handle 616 prevent hand injuries during operation. These structural combinations make the device more convenient and stable during use.

[0038] During the application of this device, its arc-shaped display screen 10 is powered by a plug-in plug and socket, which makes it easy to quickly connect and disconnect power.

[0039] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
