Description

Technical Field

[0001] This utility model relates to the field of advertising light box technology, specifically a large advertising light box that avoids deformation. Background Technology

[0002] Large advertising light boxes may experience panel deformation after prolonged use. Deformation of the transparent panel can distort advertising images and figures, resulting in poor display quality.

[0003] There are two main reasons for the deformation of large advertising light boxes: 1. There is not enough support structure inside the advertising light box to support the panel; 2. The overall connection strength of the advertising light box is insufficient, which makes the advertising light box easy to deform when affected by external weather factors and its own weight.

[0004] Therefore, it is necessary to design a large advertising lightbox that avoids deformation in order to ensure the overall connection strength and increase internal support, thereby preventing the lightbox from deforming after long-term use. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a large advertising light box that avoids deformation, so as to ensure the overall connection strength and increase internal support, thereby preventing the light box from deforming after long-term use.

It includes a PC composite board, a transparent support component, a triangular plate, galvanized edge-fastening components, a galvanized edge-fastening outer plate, a steel pipe frame, a steel plate, an aluminum plate, and LEDs. The back plate of the galvanized edge-fastening components is fixed to the wall using threaded rods and structural adhesive. The threaded rods pass through the steel plate, the back plate of the galvanized edge-fastening components, and the wall, and are secured with welded nuts. Structural adhesive is applied to the contact surface between the back plate of the galvanized edge-fastening components and the wall. The front side of the back plate of the galvanized edge-fastening components is equipped with... The steel pipe frame is fixed to the front of the aluminum plate with screws. Several LEDs are installed on the front surface of the aluminum plate. A galvanized outer plate is installed above the top plate and below the bottom plate of the galvanized edge fastener. The end of the PC composite plate is embedded between the edge of the galvanized edge fastener and the edge of the galvanized outer plate. A transparent support is installed between the PC composite plate and the back plate of the galvanized edge fastener. A triangular plate is installed between the back plate and the edge of the galvanized edge fastener, and the side of the triangular plate abuts against the top or bottom plate of the galvanized edge fastener.

[0007] The power cord of the LED is connected to an external power source.

[0008] The PC composite board includes a transparent PC board, DuPont paper, and a light-white PC board. The transparent PC board is disposed on the outside of the light-white PC board, and the DuPont paper is disposed between the transparent PC board and the light-white PC board.

[0009] The galvanized edge-fastening outer plate and the top or bottom plate of the galvanized edge-fastening component are fixed with countersunk screws.

[0010] The transparent support is a bent structure with support feet. Each end of the bent structure has a support foot, the two support feet abut against the back plate of the galvanized edge fastener, and the bent structure abuts against the PC composite board.

[0011] The installation positions of the transparent support and triangular plate are staggered from the LED arrangement positions.
