Description

Technical Field

[0001] This utility model belongs to the field of desktop lightbox technology, specifically relating to a snap-on desktop lightbox. Background Technology

[0002] In the field of advertising and display, desktop double-sided light boxes are a common and effective promotional tool, widely used in various commercial venues, exhibitions, and event sites. They are mainly used to display promotional images to attract consumers' attention and thus promote products or services.

[0003] However, current desktop double-sided light boxes on the market have many problems that urgently need to be solved. In terms of structural design, there is strong coupling between their components. While this structure ensures overall stability to a certain extent, its drawbacks are also quite obvious. Once a single component fails, due to the strong interrelationships between the components, it is impossible to replace the damaged part individually; often, the entire light box needs to be replaced. This undoubtedly increases replacement costs significantly, resulting in wasted resources and economic losses.

[0004] From an aesthetic and protective perspective, existing advertising leaflet replacement ports are mainly located at the top or side of the light box. This arrangement disrupts the continuity of the light box frame, making the overall appearance less harmonious and aesthetically pleasing. Furthermore, the presence of the replacement port exposes the internal structure of the light box, making it susceptible to contamination from external environmental factors such as dust and moisture. This not only affects the display of the advertising images but may also lead to internal circuit malfunctions due to long-term contamination, reducing the light box's lifespan and reliability. Therefore, developing a new type of desktop light box to overcome these shortcomings is of significant practical importance and meets market demand. Utility Model Content

[0021] Example

[0022] Please see Figure 1-3 The present invention provides the following technical solution: a snap-on desktop lightbox, including a light box assembly and a lamp holder assembly. The light box assembly includes a main frame 1, with an insertion port 2 at the center of the bottom end of the main frame 1. A baffle 3 is installed in the insertion port 2 of the main frame 1. A light guide plate 7 is inserted inside the main frame 1. A light box piece 6 and a panel 5 are arranged sequentially on both sides of the light guide plate 7. The lamp holder assembly includes a housing 8, with a positioning groove 9 at the top of the housing 8. The bottom end of the main frame 1 is connected to the positioning groove 9 of the housing 8 by a snap-on method. A light strip 10 is installed at the center of the positioning groove 9. The baffle 3 is placed on top of the light strip 10. A power module 11 is installed at the bottom of the housing 8. The light strip 10 and the power module 11 are electrically connected.

[0023] In order to ensure that the light strip 10 can provide precise and efficient bottom lighting for the advertising image inside the main frame 1, and to ensure that the light penetrates the advertising content evenly, thereby improving the display effect and optimizing the lighting layout, in this embodiment, as a preferred technical solution of this utility model, a light-transmitting opening 12 is provided at the center of the baffle 3, and the light strip 10, the light-transmitting opening 12 and the socket 2 are arranged in a co-linear manner.

[0025] In order to effectively protect the power module 11 from external impacts, dust accumulation and moisture corrosion, and ensure the stable operation of the power module 11, and at the same time, to facilitate the opening and closing of the power cover 13 when the power module 11 needs to be repaired or replaced, in this embodiment, as a preferred technical solution of the present invention, the housing 8 is located at the bottom of the power module 11 and is connected to the power cover 13 by a snap-fit ​​method.

[0026] To enhance the stability of the lightbox when placed on a support surface such as a desktop, in this embodiment, as a preferred technical solution of the present invention, anti-slip pads 4 are fixed at the four corners of the bottom of the housing 8.

[0027] In order to improve the overall structural strength and stability of the light box, reduce structural weak points caused by splicing gaps, enhance the protective performance of the light box, reduce the risk of external pollutants entering the light box, and thus extend the service life of the light box, in this embodiment, as a preferred technical solution of the present invention, the main frame 1 and the shell 8 are both integrally formed structures.

[0028] In summary, with the help of the above-described technical solution of this utility model,

[0029] The promotional display structure consists of a main frame 1, which serves as the supporting structure for the light box assembly and provides the installation base for all internal components. The internally inserted light box panel 6 contains the core display content. The light box panel 6 carries promotional images or text and features excellent light transmittance and color rendering, ensuring clear presentation of the promotional content. The side panels 5, arranged sequentially on both sides, protect against dirt and secure the internal structure. The light guide plate 7 is a crucial optical component; it evenly diffuses the light emitted from the light strip 10, ensuring uniform illumination of the light box panel 6 and preventing uneven lighting, thereby enhancing the display effect of the promotional image.

[0030] Structure of Baffle 3 and Socket 2: Socket 2, located at the center of the bottom of the main frame 1, is used to install display components such as the lightbox panel 6. Baffle 3 is installed inside socket 2. Baffle 3 serves two purposes: firstly, it seals the bottom of the lightbox assembly, preventing dust and other foreign objects from entering the lightbox from the bottom. Secondly, the light-transmitting opening 12 at the center of baffle 3 is aligned with the light strip 10 and socket 2, allowing light emitted from the light strip 10 to enter the main frame 1 through the light-transmitting opening 12, providing bottom lighting for the advertising display and enhancing the overall lighting effect. The inner walls of socket 2 and the sides of baffle 3 of the main frame 1 are detachably connected via a snap-fit ​​mechanism. This connection method facilitates easy disassembly and installation of baffle 3 when cleaning or replacing internal components.

[0031] Positioning and Connection Structure: The positioning groove 9 on the top of the housing 8 of the lamp holder assembly is used for snap-fitting with the bottom of the main frame 1. This snap-fit ​​method not only enables rapid assembly of the light sign assembly and the lamp holder assembly, but also ensures the stability of the connection between the two. The design of the positioning groove 9 allows the main frame 1 to be accurately installed in place, ensuring the stability of the entire light box structure and preventing shaking or displacement during use.

[0032] Lighting and Power Supply Structure: The light strip 10 installed at the center of the positioning slot 9 is the main lighting source. The light strip 10 uses high-brightness, low-energy-consumption LED beads, providing uniform and bright light to adequately illuminate the advertising images inside the light board assembly. The light strip 10 is electrically connected to the power module 11 installed at the bottom of the housing 8, providing a stable power supply to the light strip 10. The power module 11 has voltage regulation and filtering functions to ensure stable current input to the light strip 10 and extend its service life. A power cover 13 is connected to the bottom of the power module 11 in a snap-fit ​​manner. The power cover 13 protects the power module 11 from external impacts or dust contamination, and also facilitates disassembly for maintenance or replacement of the power module 11.

[0033] Advantages of integrated structure: Both the main frame 1 and the shell 8 are integrally molded structures. The integral molding process makes the structure of the frame and shell 8 stronger and reduces structural weaknesses caused by splicing gaps. This not only improves the overall stability of the lightbox but also enhances its protective performance, reducing the possibility of external dust, moisture, and other contaminants entering the lightbox, thereby improving the lifespan and reliability of the lightbox.
