LED (light emitting diode) screen splicing structure and LED screen

Abstract

The invention discloses an LED (light emitting diode) screen splicing structure and an LED screen. The LED screen splicing structure comprises a first box and a second box, the first box and the second box are spliced mutually, the first box comprises a first side wall facing the second box, the second box comprises a second side wall opposite to the first side wall, the first side wall is provided with a plurality of limiting faces in different angles, the second side wall is provided with a slide groove corresponding to position of the limiting faces, and a wedged slider is movably arranged in the slide groove. The first box and the second box are fixedly connected through a spring connector penetrating the wedged slider, and an included angle between the first box and the second box is defined by the wedged slider and the limiting faces jointly. Angle nonuniformity in splicing is realized by matching of the wedged slider and the limiting faces, assembly and fastening of the two boxes are realized by the aid of a spring connection lock, and easiness in angle adjustment, mechanism simplicity, steadiness in connection for use, less proneness to loosing in repeated disassembly, part design and cost reduction, easiness in processing and accordance with market requirements are realized.

Description

technical field [0001] The invention relates to the technical field of splicing electronic equipment, in particular to an LED screen splicing structure and an LED screen using the splicing structure. Background technique [0002] LED display screen is a new type of flat-panel display device that appeared in the 1990s. Due to its clear picture, high brightness, and bright colors, it has gradually become the only one in the field of public multimedia display. LED displays are also widely used, such as light box advertisements, outdoor billboards, indoor screen displays, etc. However, in the case of some large display screens composed of multiple smaller display screens, it is usually necessary to use a connecting device to assemble multiple display screen modules together. However, at present, many connection devices are fixed connections, and the angle between the light boxes cannot be adjusted, which cannot meet the diverse needs of the market. Although, there are some ang...

AI Technical Summary

Problems solved by technology

But at present, many connection devices are fixed connections, and the angle between the light boxes cannot be adjusted, which cannot meet the diverse needs of the market.

Although, there are some angle-adjustable adjusting devices in the prior art as the publication number is (the patent document of CN102858125A), this adjusting device is installed between two display screen cabinets, can adjust two adjacent display screen cabinets as required According to different use requirements, the angle between the two display cabinets can be adjusted to different angles, but its applicability is not enough; 1. Due to the many adjustable angles, there are many parts and mechanisms There will also be a large number of assembly tolerances on the surface, which will loosen due to frequent disassembly and assembly, resulting in safety hazards

2. The adjustment angle is not smooth, easy to get stuck

3. Angle adjusters on the market have a short service life and are easily damaged
