[0002] In modern society, as an important advertising display and information dissemination tool, light boxes are widely used in various scenarios such as commercial places, public areas, and transportation hubs. The existing light box structures are relatively simple, usually a simple closed box that can be opened. Most of the light box films of such light boxes are directly fixedly installed inside the box body, resulting in the installation and replacement of the light box films requiring opening the light box and then being completed by professional personnel with the help of specific tools. This makes the operation process of replacing the light box film complex, which not only increases the maintenance cost but also may lead to time waste and low efficiency during the replacement process. To solve the deficiencies of the existing technology, we propose a light box convenient for replacing light box films. Content of the Utility Model
