Description

Technical Field

[0001] This utility model relates to an advertising billboard, specifically an advertising billboard with the function of changing advertisements. Background Technology

[0002] In the advertising field, traditional lightbox billboards are widely used because they can be illuminated at night. However, existing billboards often have several design flaws, specifically in the following aspects: Traditional billboards typically use ordinary light tubes or LED modules for internal lighting, lacking professional light distribution design. This easily leads to uneven light distribution, resulting in obvious "light spots" or bright and dark stripes, making the poster content appear harsh and glaring, seriously affecting the visual appeal and communication effectiveness of the advertisement.

[0003] Replacing posters often requires the use of specialized tools to disassemble multiple fasteners on the exterior of the billboard (such as screws and clips), a complex and time-consuming process. This not only increases the labor costs of maintenance but also makes the updating of advertising content inefficient, failing to meet the needs of scenarios requiring frequent advertising changes.

[0004] When the internal lighting tubes fail, repair and replacement are extremely inconvenient. It usually requires disassembling the billboard panel first, and then dealing with complex wiring to remove the tubes. The entire process poses electrical safety risks, demands a certain level of technical skill from maintenance personnel, and is costly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an advertising board with the function of changing advertisements, so as to solve the problems existing in the background art.

[0006] The billboard with replaceable advertising function of this utility model is achieved through the following technical solution, including the billboard body and replaceable posters; The main body of the billboard has a placement cavity on its front, and a replaceable poster is placed inside the placement cavity; the bottom of the placement cavity has a light-diffusing structure, which illuminates the poster so that its content can be displayed at night; a transparent panel is provided at the placement cavity through a positioning structure, which supports the poster and prevents it from deforming.

[0007] As a preferred technical solution, the light-diffusing structure includes multiple fixed cavities, fixed lamp tubes, and a light-diffusing plate disposed at the bottom of the placement cavity; The fixed lamp tube is fixedly installed in the fixed cavity by a magnetic structure, and the fixed lamp tube is flush with the placement cavity; the light diffusion plate is placed on the placement cavity and corresponds to the position of the fixed lamp tube, and the light diffusion plate uniformizes the light emitted by the LED beads on the fixed lamp tube.

[0008] As a preferred technical solution, a connecting contact point is provided on the back of the fixed lamp tube, and a contact point corresponding to the connecting contact point is provided on the fixing cavity; the connecting contact point and the contact point are positioned to supply power to the fixed lamp tube.

[0009] As a preferred technical solution, the fixed lamp tube is provided with a lamp bead mounting cavity, and the LED lamp beads are set in the lamp bead mounting cavity to prevent the lamp beads from protruding and thus affecting the installation of the light diffuser.

[0010] As a preferred technical solution, the positioning structure includes a positioning frame disposed inside the transparent panel, and the positioning frame matches the inner edge of the placement cavity. When the poster is placed in the placement cavity, the transparent panel is positioned with the placement cavity under the action of the positioning frame.

[0011] As a preferred technical solution, locking screws are provided on all four sides of the transparent panel, and locking holes corresponding to the locking screws are provided on the main body of the billboard. When the transparent panel is fixed to the main body of the billboard, it is fixed by the locking screws and locking holes.

[0012] As a preferred technical solution, hanging holes are provided on all four sides of the back of the billboard body to facilitate the hanging of the billboard body.

[0013] As a preferred technical solution, the main body of the billboard is also equipped with a power supply board, which is connected to power supply contacts to supply power to the fixed lamp tubes; the power supply board is connected to an external power source through a power cord.

[0014] As a preferred technical solution, the magnetic attraction structure includes a magnetic attraction groove disposed at the bottom of the fixing cavity and a magnetic attraction block disposed on the fixing lamp tube; the fixing lamp tube and the fixing cavity are magnetically fixed together by the magnetic attraction block and the magnetic attraction groove. The beneficial effects of this utility model are: This invention utilizes a light-dispersing structure at the bottom of the placement cavity to evenly disperse the light emitted by the LED beads, providing soft and glare-free illumination of the poster. This ensures that the advertising content remains clear and eye-catching at night or in low-light environments, greatly enhancing the display effect of the billboard.

[0015] This invention features a detachable transparent panel and positioning frame structure, allowing posters to be quickly placed and removed simply by opening the panel. This simple operation greatly reduces the time and labor costs associated with changing advertising content.

[0016] This utility model uses a magnetic structure to fix the lamp tube, and is equipped with connecting contact points and contact contacts for power supply. When the lamp tube needs to be replaced or repaired, it can be directly installed or removed without tools, achieving "plug and play" and making maintenance extremely convenient.
