[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0027] A lightbox frame structure, such as Figure 1 and Figure 2 As shown, the light box includes an integrally molded outer frame 1, a panel 2 connected to the outer frame 1, and a mounting bracket on the inner wall of the outer frame 1. A fixing component is provided between the panel 2 and the mounting bracket, and the panel 2 is fixed to the mounting bracket by the fixing component. The mounting bracket consists of several protruding bosses 3 on the inner wall of the outer frame 1, and the mounting bracket directly provides a mounting base for components such as the panel 2 and the light strip 7. In this embodiment, the outer frame 1 and the bosses 3 are integrally molded by injection molding, avoiding the problem of additional connecting parts required by traditional split frames. This not only simplifies the overall structure of the light box but also reduces positioning errors during assembly, greatly improving the efficiency of mass production. At the same time, it enhances the structural strength of the outer frame 1 and the mounting bracket, preventing the mounting bracket from loosening after long-term use.

[0028] like Figures 3 to 5 As shown, the fixing assembly specifically includes a first magnetic strip 4 fixed to the mounting bracket, and a second magnetic strip 5 fixed to the side of the panel 2 facing the mounting bracket. The panel 2 is fixed to the mounting bracket by the attraction between the second magnetic strip 5 and the first magnetic strip 4. The second magnetic strip 5 can be fixed to the panel 2 by adhesive strips or glue, and the first magnetic strip 4 can also be fixed by adhesive strips or glue.

[0029] In this embodiment, the outer frame 1 is a rectangular frame with open front and rear sides. Panels 2 are connected to both the front and rear sides of the outer frame 1, and both sides can be used for advertising display. Mounting brackets are provided on the inner walls of both the left and right ends of the outer frame 1. The mounting brackets are a number of protrusions 3 arranged along the height direction of the outer frame 1. The number of protrusions 3 can be set according to actual needs. Protrusions 3 can be omitted at the mounting locations of components such as speakers, power supplies, and circuit boards to avoid interference with component assembly.

[0030] Specifically, mounting plates 6 are provided on both the front and rear sides of the mounting frame. The mounting plates 6 extend along the height direction of the outer frame 1. The mounting plates 6 and the bosses 3 are fixed together by screws. The screws pass through the preset holes of the mounting plates 6 and the corresponding holes of the bosses 3 in sequence to form a stable fixation. The first magnet is fixed on the mounting plate 6. The mounting plate 6 fills the unevenness caused by the discrete arrangement of the bosses 3, providing a flat and continuous mounting carrier for the first magnetic strip 4, so that the first magnetic strip 4 can be laid completely along the height direction of the outer frame 1. In addition, the first magnetic strip 4 is fixed on the mounting plates 6 at both ends of the outer frame 1, and the second magnetic strip 5 is fixed on both ends of the panel 2 facing the mounting frame, improving the connection stability of the panel 2.

[0031] When panel 2 is fixed on the mounting bracket, the edge of panel 2 fits against the inner wall of the outer frame 1, or has a small gap to avoid friction damage. This positional correspondence ensures accurate magnetic attraction and eliminates the need to repeatedly adjust the position of panel 2.

[0032] Each of the two mounting brackets has a light strip 7 on one side facing each other. The light strip 7 extends along the height of the outer frame 1. The inner side of the protrusion 3 has a flat plate. The light strip 7 can be fixed to the flat plate with glue, adhesive strip, or screws. The light strip 7 is located between the advertising posters on the front and back sides, and can evenly diffuse light towards the center of the lightbox, covering the display areas on the front and back sides.

[0033] The side wall of the outer frame 1 has a speaker hole 8 and a data cable connection through hole 9, which correspond to the internal component mounting positions. Both are holes directly opened when the side wall of the outer frame 1 is integrally formed, without the need for subsequent drilling or cutting steps.

[0034] The inner wall of the outer frame 1 has a protruding pivot bracket 12 for mounting the pivot. The upper and lower ends of the left and right ends of the outer frame 1 also have pivot brackets 12, which are integrally formed with the outer frame 1. The pivot bracket 12 has a shaft hole in the center that matches the pivot. When it is adapted to a four-axis model, two shaft holes can also be provided. The two ends of the pivot are rotatably connected to the shaft holes of the pivot bracket 12. The pivot is used to scroll advertising posters (not shown in the figure).

[0035] The bottom of the outer frame 1 is provided with support feet 10, which protrude from the front and rear sides of the outer frame 1 to increase the support area. At least two support feet 10 are provided; in this embodiment, two support feet 10 are provided, located near the left and right ends of the outer frame 1 respectively, to improve the stability of the outer frame 1 when placed and to prevent wear on the bottom of the device. Corresponding bolt holes 13 are provided at the bottom of the outer frame 1. Bolts are passed through the support feet 10 and then through the bolt holes 13, and nuts are screwed onto the ends of the bolts to secure them.

[0036] In addition, this embodiment also proposes a desktop scrolling lightbox, including the above-mentioned lightbox outer frame 1 structure.
