Description

Technical Field

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

[0002] An LED display screen is a flat-panel display device based on light-emitting diode (LED) technology. It displays images, text, and video content by controlling countless tiny LED beads to emit light. Its core light-emitting element is a pixel composed of red, green, and blue LED chips. Full-color display is achieved by adjusting the brightness ratio of different colored LEDs. These densely packed pixels, controlled by a driving circuit, can display dynamic images at a high refresh rate, maintaining clear visibility even in direct sunlight. LED displays adopt a modular design concept, consisting of multiple standard-sized display units spliced ​​together. Their size and shape can be flexibly adjusted according to application requirements, ranging from small screens of a few square meters to giant screen systems covering an entire building wall. Compared to traditional display technologies, LEDs have significant advantages: high luminous efficiency and low energy consumption, a lifespan generally exceeding 50,000 hours, and the ability to operate in a wide temperature range from -30℃ to 60℃. With breakthroughs in Mini LED and Micro LED technologies, the pixel pitch of displays has been reduced to below the millimeter level, resulting in finer image quality and a wider viewing angle. Currently, LED displays are widely used in commercial advertising, live sports broadcasts, traffic information dissemination, stage performances, and command and control centers, and dominate the outdoor large-screen market. Their self-emissive nature eliminates backlight dependence, and combined with anti-glare coatings and anti-reflective treatment technology, ensures vivid and clear visual effects under various lighting conditions.

[0003] However, LED displays have significant limitations in the splicing process. Precise alignment between modules and complex wiring are required, which is time-consuming, labor-intensive, and relies on professional personnel. After splicing, if local display deviations or angular tilts occur, adjustments are extremely inconvenient—operations such as pixel pitch calibration and flatness fine-tuning require repeated disassembly and reassembly of modules, which not only affects the overall structural stability but also significantly increases the difficulty of later maintenance, making it difficult to quickly respond to changes in display requirements caused by changes in the on-site environment. Utility Model Content

[0004] The purpose of this invention is to provide a splicable LED display screen, which solves the problems of inconvenient splicing of LED display screens and inconvenient adjustment after splicing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a splicable LED display screen, including a mounting base and a connecting base, with a hinge installed between the mounting base and the connecting base.

Through the design of the adjustment mechanism, the distance between the mounting base and the connecting base can be adjusted.

[0009] Preferably, there are multiple limiting grooves, which are symmetrically distributed on the connecting seat. The design of the limiting grooves can work with the limiting rod to limit the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model innovatively configures components such as a pressure block, a threaded rod, and a guide rod. Rotating the threaded rod drives the pressure block to generate a threaded transmission, causing the pressure block to precisely press the display screen, achieving stable positioning of the display screen on the mounting base and connecting base. This design simplifies the complex positioning and fixing process in traditional splicing, eliminating the need for multiple people or specialized tools. Module installation can be completed quickly in a single operation, effectively solving the problems of cumbersome steps and low efficiency in LED display splicing.

[0014] 2. This utility model, by setting up components such as a connecting plate, a limiting block, and a limiting rod, allows the mounting base to be released by simply pulling the limiting rod away from the connecting base, causing it to slide out of the limiting groove of the connecting base. This enables flexible adjustment of the mounting base angle, allowing a single person to easily perform fine-tuning of the tilt angle of the spliced ​​display screen. It solves the problem of repeated disassembly and reassembly and cumbersome operation required for angle adjustment in traditional LED displays, thus improving the convenience of angle adjustment.

A display screen 4 is slidably connected inside the mounting base 1 and the connecting base 2. A pressure block 5 is slidably connected inside the mounting base 1 and the connecting base 2, and the pressure block 5 contacts the display screen 4. A guide rod 51 is fixedly connected inside the mounting base 1 and the connecting base 2. A guide block 52 is fixedly connected to the outside of the guide rod 51. The guide rod 51 is slidably connected to the pressure block 5, and the guide block 52 is slidably connected to the pressure block 5. The design of the guide block 52 can limit the pressure block 5. The mounting base 1 and the connecting base 2 are rotatably connected by a threaded rod 53, which is threadedly connected to the pressure block 5. The mounting base 1 and the connecting base 2 are rotatably connected by a retaining ring 54, which is fixedly connected to the threaded rod 53. The design of the retaining ring 54 can limit the threaded rod 53. The upper end of the mounting base 1 and the connecting base 2 is in contact with a knob 55, which is fixedly connected to the threaded rod 53. The mounting base 1 and the connecting base 2 are provided with an adjustment mechanism 6.

[0022] Please see Figure 2-4 The adjusting mechanism 6 includes a connecting plate 61. The lower end of the mounting base 1 contacts the connecting plate 61, and the connecting plate 61 contacts the connecting base 2. The upper end of the connecting plate 61 is fixedly connected to a rotating shaft 62, which is connected to the mounting base 1 via a bearing. The upper end of the connecting plate 61 is fixedly connected to a limiting block 63, which is slidably connected to the connecting base 2. A limiting rod 64 is slidably connected inside the limiting block 63. The connecting base 2 has multiple limiting grooves 65, which are symmetrically distributed on the connecting base 2. Through the design of the limiting grooves 65, they can work with the limiting rod 64 to limit the connection plate 61.

[0023] Please see Figure 2-4 The limiting rod 64 is slidably connected to the connecting plate 61 and the limiting groove 65. A limiting ring 66 is fixedly connected to the outer side of the limiting rod 64. The limiting ring 66 is slidably connected to the limiting block 63 and contacts the connecting seat 2. Through the design of the limiting ring 66, the limiting rod 64 can compress the spring 67. A spring 67 is provided on the outer side of the limiting rod 64.

Through the design of the adjusting mechanism 6, the distance between the mounting seat 1 and the connecting seat 2 can be adjusted.

[0024] The specific implementation process of this utility model is as follows: When in use, the display screen 4 is placed in the mounting base 1 and the connecting base 2 respectively, and then the knob 55 is rotated to make the knob 55 drive the threaded rod 53 to rotate, so that the threaded rod 53 and the pressure block 5 have threaded movement, so that the pressure block 5 moves on the threaded rod 53 and contacts the display screen 4, so that the pressure block 5 can limit the display screen 4.

[0025] By moving the pull plate 68 away from the connecting seat 2, the pull plate 68 drives the limiting rod 64 to move, which in turn drives the limiting ring 66 to move. The limiting ring 66 then compresses the spring 67, and the limiting rod 64 slides out of the limiting groove 65. This releases the limiting of the connecting plate 61 and the limiting block 63, allowing the mounting seat 1 to rotate and thus adjust the angle between the two displays 4.
