Description

Technical Field

[0001] This application relates to the field of hanging light box technology, and in particular to a hanging light box. Background Technology

[0002] The most widespread use of hanging light boxes is as advertising light boxes and wayfinding light boxes. They are constructed with acrylic or PVC panels, featuring acrylic or self-adhesive lettering, using fluorescent tubes as the light source, and mounted on angle iron brackets to make the lettering stand out and thus serve an advertising or directional purpose.

[0003] An existing patent (publication number: CN219658332U) discloses a hanging advertising lightbox, including a box body. A light guide plate and light strips are provided on one inner wall of the box body, with the light strips located on both sides of the light guide plate. An installation plate is provided on one inner wall of the box body, and an advertising soft film is installed on one side wall of the installation plate. Slots are provided on both outer walls of the box body, and a fixing frame is slidably engaged on one side wall of the slots. A sliding groove is provided on the top outer wall of the box body, and a hanging plate is slidably engaged inside the sliding groove. A knob is threaded to the top of the hanging plate, and the hanging plate is fixed by the knob. A connecting rod is installed at the top of the hanging plate, and a height adjustment component is provided at the top of the connecting rod. A fixing plate is installed at the top of the height adjustment component. Tempered glass is installed on one side wall of the fixing frame. This allows the advertising lightbox to be quickly removed for advertising replacement, effectively improving the efficiency of advertising replacement and installation, and reducing the probability of workers being injured while working at height.

[0004] While the aforementioned technologies can achieve height adjustment, the box body and the fixed frame are connected by a sliding snap. When replacing the advertisement, the box body and the fixed frame need to be separated. After separation, the fixed frame needs to be held or placed in a safe place before the advertisement can be replaced. The replacement process is quite cumbersome. To solve the above problems, a hanging light box is proposed. Utility Model Content

[0005] The purpose of this application is to provide a hanging light box that uses a folding support assembly to open and close the box body and lid, thus solving the problems mentioned in the background art.

[0006] The present application provides a hanging light box with the following technical solution: A hanging light box includes a light box assembly and a grounding assembly. The light box assembly includes a light box body and a double-sided lamp plate installed on the inner wall of the light box body. The top of the light box body has two flip grooves on both sides. The light box body has rotatable covers installed on both sides. Each cover has a flip block fixedly connected to its top. The flip block is adapted to the flip groove. The interior of the light box body is equipped with a folding support assembly.

[0007] The folding support assembly includes four recessed fixing blocks fixedly connected to the bottom wall of the light box body. Two protruding connecting blocks are installed on the inner wall of each double-sided light panel. The recessed fixing blocks and protruding connecting blocks are adapted to each other. Two first connecting pieces are installed on both sides of the inner wall of the light box body via screws. A first support rod is hinged to one end of each first connecting piece. A slot is formed on the inner wall of each first support rod. A rotatable rotating column is installed at one end of each first support rod.
