Abstract

The utility model relates to the field of LED display screens, in particular to a connecting and fixing device for a plastic lampshade of an LED display screen. The technical problems that when a plastic lampshade of an LED display screen is installed, a whole non-splicing type plastic lampshade is selected, although the watching effect of the LED display screen and the waterproofness of the plastic lampshade are guaranteed, accurate butt joint is inconvenient due to the large area of the plastic lampshade, and more screws are needed for fixing, so that the plastic lampshade is not convenient to install. Therefore, the installation efficiency of workers is affected. According to the technical scheme, the connecting and fixing device for the plastic lampshade of the LED display screen comprises a frame assembly, a butt joint assembly, a positioning assembly and a lampshade assembly. By arranging the primary butt joint limiting device and the secondary fastening device, the plastic lampshade can be more easily in butt joint with the main frame when being installed, primary fixing can be completed while butt joint is completed, then the whole plastic lampshade can be clamped and fixed only through two-time operation of screwing a threaded rod, and the whole plastic lampshade can be fixed conveniently. And a worker can conveniently install the plastic lampshade, and the worker can conveniently disassemble and replace the plastic lampshade.
