Description

Technical Field

[0001] The utility model relates to the technical field of LED full-color screens, in particular to an indoor small-pitch LED full-color screen. Background Art

[0002] In the current era of digital display and information dissemination, indoor small-pitch LED full-color screens have become the preferred display medium in multiple fields such as commercial displays, conference systems, and control room monitoring due to their high definition, wide viewing angle, and excellent color expressiveness. However, despite continuous technological progress, a significant drawback of traditional indoor small-pitch LED full-color screens in terms of installation and maintenance - the lack of an effective detachable design - remains a major challenge in the industry. This section aims to delve deeply into this issue, analyze the inconveniences it causes to users and application scenarios, and provide the necessary background for subsequent innovative solutions.

[0003] Traditional indoor small-pitch LED full-color screens often adopt a fixed installation structure, which means that during the initial deployment, a professional team is required to conduct on-site measurements, customize brackets, and perform precise installation. This process not only takes a relatively long time but also incurs high installation costs, including labor, materials, and potential rework costs due to incorrect installation. Since the screen body is non-detachable, any fine-tuning or partial replacement requires careful operation to avoid damaging surrounding components, further increasing the installation difficulty and risk.

[0004] During long-term use, LED screens will inevitably encounter problems such as unit failures and brightness attenuation, which require regular inspection and maintenance. However, due to the non-detachable design, once a faulty unit appears, maintenance personnel often need to work in a limited space, which not only tests the technical level of the maintenance personnel but also greatly extends the maintenance cycle and increases the maintenance cost. In some cases, the replacement of a single module may even require the removal of the entire screen, causing unnecessary interruption to normal operation and reducing the system's usability and customer satisfaction.

[0005] With the accelerating pace of technological iteration, the replacement cycle of display screens is also shortening. Traditional non-detachable small-pitch LED full-color screens are particularly passive when faced with technological upgrades or function expansions. If users want to improve the display effect or add new functions, they often need to replace the entire screen rather than simply upgrading or adding modules, which is undoubtedly a waste of resources and limits the user's flexibility and return on investment. Especially in the rental market or exhibition venues where the layout needs to be adjusted frequently, this design flaw greatly restricts the reuse value of the screen and the creative display space.

[0006] After the installation of the non-removable full-color screen, its position and form are basically fixed, making it difficult to be flexibly adjusted according to actual usage requirements. For places with limited space or where the layout needs to be changed frequently, this fixed design may lead to inefficient use of space and an inability to maximize the integration of the display effect and the environment. Especially in situations where the display area needs to be temporarily enlarged or reduced, the fixed screen size becomes a limiting factor, which is not conducive to achieving the optimal visual communication effect.

[0007] Therefore, how to provide an indoor small-pitch LED full-color screen is an urgent problem that needs to be solved by those skilled in the art. Utility Model Content

[0008] An object of the present utility model is to provide an indoor small-pitch LED full-color screen. In the present utility model, by swinging the swing plate, the swing of the swing plate drives the rotating rod to rotate, and the rotation of the rotating rod drives the locking plate to rotate, so that the long axis end of the locking plate swings into the locking groove, and then it is fixed by the mounting bolt at the end of the swing plate to prevent the swing plate from swinging randomly, resulting in the locking plate disengaging from the locking groove and reducing the locking of the lamp board group. A plurality of lamp board groups are provided, and they have good splicing performance and are convenient for replacement.

[0009] An indoor small-pitch LED full-color screen according to an embodiment of the present utility model includes a color screen frame, a lamp board group, a closing plate and a locking component. Among them, the lamp board group is slidably installed in the color screen frame, the closing plate is fixedly installed at the open end of the color screen frame, and the locking component is rotatably installed at the upper and lower ends of the color screen frame.
