[0023] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0024] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0025] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the elements, components, regions, layers, or segments discussed below may be referred to as second elements, components, regions, layers, or segments without departing from the teachings of the exemplary embodiments.

[0026] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "rear," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0027] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0028] Please see Figure 1 and Figure 2 As shown, the lightbox frame provided in Embodiment 1 of this utility model includes a frame 10. The injection-molded frame 10 has thick and thin sections along its length, with thicker sections requiring support and thinner sections requiring bending. Multiple frame 10s are connected end-to-end to form a side frame, which is detachable. Supporting ribs 20 are used to install a light guide plate, forming a lightbox with the side frame. A first recessed step 11 is provided on the front side of one side of the frame 10, and a second recessed step 12 is provided on the back side of the other side of the frame 10, which overlaps with the first recessed step 11. Adjacent frame 10s are connected by the staggered overlap of the first and second recessed steps, resulting in a flat overall surface that prevents light leakage and eliminates the need for additional glue to prevent light leakage. A limiting recess 13 for fixing the light guide plate is provided at the top of the frame 10, and several supporting ribs 20 for supporting the light guide plate are provided on the inner wall of the frame 10. A connecting member 21 extends from the bottom of the supporting rib 20, and the frame 10 is mounted on a mounting base plate (not shown) via the connecting member 21. In use, several frame pieces 10 are assembled together in sequence. The adjacent frame pieces 10 are interlocked by the first recessed step 11 and the second recessed platform 12, forming a flat surface that does not leak light, so there is no need to apply glue to prevent light leakage. The frame pieces 10 are fastened to the mounting base plate (not shown) by fasteners passing through the through holes 24 of the connector 21, so that several frame pieces 10 form a complete side frame. Then, the light guide plate is installed on the limiting recessed platform 13 at the top of the frame piece 10.

[0029] Please see Figure 3 and Figure 4As shown in Embodiment 1 of this utility model, a slot 22 is provided on the top of the supporting rib 20. The slot 22 is used to store the light-transmitting soft cloth. The inner wall of the slot 22 is provided with a buckle 23 for fixing the cloth strip. The light-transmitting soft cloth is correspondingly snapped into the slot 22, and the soft cloth is further fixed by the buckle. Therefore, the buckle can tightly embed the light-transmitting soft cloth in the slot 22, which not only fixes the light-transmitting soft cloth, but also effectively prevents rainwater from entering the light box, ensuring the service life of the light box. Alternatively, a cloth strip can be sewn directly around the light-transmitting soft cloth. The buckle 23 can firmly fasten the cloth strip around the light-transmitting soft cloth, eliminating the need for additional windproof strips, thus reducing material and installation costs.

[0030] In the first embodiment of this utility model, the slots 22 of the multiple supporting ribs 20 can also be staggered to facilitate the installation and fixing of multiple layers of light-transmitting soft cloth and light-transmitting screen to achieve dust prevention or to form different patterns to create different optical effects; metal strips (not shown) or metal blocks (not shown) can be embedded in the frame 10 and the supporting ribs 20. The metal strips or metal blocks are used to enhance the support strength. Specifically, plastic can be injected first and then the metal strips or metal blocks can be embedded, or the metal strips or metal blocks can be inlaid and injection molded at the same time as injection molding; such a plastic-metal composite frame has good fixed support strength and is easy to bend and form.

[0031] In the first embodiment of this utility model, the connector 21 is provided with a through hole 24, and the connector 21 is locked onto the mounting base plate (not shown) by fasteners passing through the through hole 24 to form any desired shape.

[0032] In the first embodiment of this utility model, the mounting base plate is provided with a plurality of LED light sources (not shown); the light guide plate (not shown) is an acrylic plate, a transparent PC plate or a transparent resin plate, and other light-transmitting materials may also be used.

[0033] In the first embodiment of this utility model, the supporting rib 20, the connecting member 21 and the frame 10 are integrally injection molded; since the injection molded frame is in the shape of a flower cutter, it can be bent into any shape during use and installation, making it quick, simple and convenient to use and install.

[0034] In the first embodiment of this utility model, patterns such as flowers can be provided on the outer surface of the frame 10 to increase the aesthetics of the frame 10.

The frame 30 has several openings 31 spaced apart. The bottom end of each opening 31 extends outward to provide a slot 32 for fixing the translucent lamp cloth. The two side walls of the openings 31 are provided with anti-slip strips 33 to increase friction. The anti-slip strips 33 increase the friction experienced by the translucent lamp cloth within the slot 32, preventing the translucent lamp cloth from being blown away by strong winds and detaching from the slot 32. The anti-slip strips 33 can secure the adhesive strips around the translucent lamp cloth within the slot 32. Above the anti-slip strips 33 are buckles 34 for fixing the adhesive strips. The buckles 34 can firmly hold the adhesive strips of the translucent lamp cloth in place, eliminating the need for additional windproof strips and reducing material and installation costs.

[0036] In the second embodiment of this utility model, the slot portion 32 is provided with a retaining strip (not shown) for holding the light-transmitting soft cloth. The light-transmitting soft cloth is correspondingly engaged into the slot portion 32, and the retaining strip further secures the light-transmitting soft cloth within the slot portion 32. Therefore, the retaining strip can tightly embed the light-transmitting soft cloth within the slot portion 32, which not only fixes the light-transmitting soft cloth but also effectively prevents external rainwater from entering the light box, ensuring the lifespan of the light box. Alternatively, adhesive strips can be sewn directly around the perimeter of the light-transmitting soft cloth. Metal strips (not shown) or metal blocks (not shown) can be embedded in the frame 30 and the slot portion 32. The metal strips or metal blocks are used to enhance the support strength. Specifically, the metal strips or metal blocks can be embedded after injection molding, or they can be inlaid during injection molding and then encapsulated. This plastic-metal composite frame has good support strength and is easy to bend and shape.

[0037] In the second embodiment of this utility model, a first recessed step 35 is provided on the front side of one side of the frame 30, and a second recessed step 36 is provided on the back side of the other side of the frame 30, which overlaps with the first recessed step.
