Abstract: A portable cylindrical light box, including a strut, an advertising fabric, a fixed profile and a transparent film. An inner wall of the advertising fabric is sewn with a first silicone strip. An outer wall of the first silicone strip abuts the transparent film. A second silicone strip is adhered to the bending portion of an outer wall of the transparent film. The groove is provided on the strut. An outer wall of the fixed profile is fixed with a light bar including an adhesive layer, a soft base layer adhesively connected to the fixed profile by the adhesive layer, and an LED bead SMD fixed on the soft base layer. The upper and lower ends of the fixed profile are respectively mounted with a bottom plate assembly and a cover plate assembly fixedly connected to the upper end of the fixed profile by screws.

Abstract: A foldable light box, including fourth profiles. The fourth profiles are assembled into a frame structure through profile connectors. The inner side walls of the fourth profiles at the upper end and the lower end of the frame structure are connected with lamp bead profiles. The inner side walls of the lamp bead profiles are stuck with LED lamp bead parts through a thermally conductive adhesive. The folding function of the entire light box is achieved by the cooperation of the foldable mechanism and the meshing mechanism provided by the present utility model. As the size is reduced, the light box is more convenient to place and transport, needs less transportation cost and space, and is more convenient to carry and display.

Abstract: A dual-use side-lighting netting lamp box with a box body. The box body has a top frame structure and a bottom frame structure. The top frame structure is formed by assembling short cross rod profiles and long cross rod profiles through top netting fixing blocks; and the bottom frame structure is formed by assembling short cross rod profiles and long cross rod profiles through bottom netting fixing blocks. A table surface at the top of the lamp box adopts a detachable structure, so that the lamp box can be used as not only a lamp box table when the table surface is placed normally, but also a single lamp box when the table surface is removed. Thus, the dual-use function is realized, the functionality of the lamp box is obviously improved, and the resource utilization rate is high.

Abstract: A method for inserting slides in a document is disclosed in the present invention. Whether the file selected to be inserted is a slide file; if the file is the slide file, a file type of the slide file is set. A file name, a file path, the file type and a file label array are extracted and stored in a memory, wherein, the file label array records orderly labels of chosen slides in the slide file. A slide object according to the file name, the file path, the file type and the labels in the file label array is constructed and inserted at a cursor position in the document. Additionally, a method for broadcasting slides is disclosed. The present invention realizes that the slide content is broadcast directly, and also realizes the broadcast characteristics such as animation and sound effect and so on. The operation is simple, time is saved, and work efficiency of users is improved.
