Description

Technical Field

[0001] This utility model relates to the field of advertising light box technology, and more specifically to a moisture-proof LED advertising light box. Background Technology

[0002] LED advertising light boxes are a new type of advertising display equipment that uses light-emitting diodes (LEDs) as the light source. The existing LED advertising light boxes can place paper advertisements inside the light box, and achieve an eye-catching effect through light reflection. They can also be used normally at night. For example, this type of advertising light box is widely used in subway stations.

[0003] However, LED advertising light boxes are prone to moisture problems during use. On the one hand, the overall sealing of the light box is insufficient, allowing external moisture to easily enter. On the other hand, the light box has an opening for placing advertising paper, and moisture can easily seep in through the opening, causing the inside of the light box to be damp. Utility Model Content

[0021] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Reference Figure 1 and Figure 2 This utility model provides a moisture-proof LED advertising lightbox, including a lightbox body 1, with several LED light strips 2 arranged on the inner wall of the lightbox body 1, and a window frame assembly 3 arranged on the front of the lightbox body 1. The window frame assembly 3 includes an outer frame plate 31, with glass fixed to the inner wall of the outer frame plate 31, and an inner insert frame 32 fixedly connected inside the outer frame plate 31. The inner insert frame 32 is inserted into the interior of the lightbox body 1, and the back of the inner insert frame 32 is close to the back of the inner wall of the lightbox body 1. The back of the outer frame plate 31 is close to the front of the lightbox body 1. Several column holes 6 are opened on the front of the lightbox body 1, and several through holes 7 are opened on the back of the outer frame plate 31. The inner walls of the column holes 6 and the through holes 7 are fixedly connected by a telescopic fixing assembly 5. The telescopic fixing assembly 5 can be extended and retracted in the open state, and is locked in the closed state. A delivery port 4 extending into the interior is opened on the top of the lightbox body 1.

[0023] In use, by opening the telescopic fixing assembly 5 and pulling the window frame assembly 3 to slide it outwards from the lightbox body 1, the telescopic fixing assembly 5 extends until the inner insert frame 32 no longer obstructs the delivery port 4. At this point, advertising paper can be inserted into the lightbox body 1 through the delivery port 4. Then, by pressing the window frame assembly 3 to reset it, the telescopic fixing assembly 5 retracts. At this time, the outer frame plate 31 adheres to the front of the lightbox body 1 to form a sealing effect, and the back of the inner insert frame 32 adheres to the inner wall of the lightbox body 1 to form a second sealing effect. The advertising paper is inside the inner insert frame 32, thereby enhancing the overall sealing effect of the advertising lightbox and preventing external moisture from entering. When the inner insert frame 32 adheres to the inner wall of the lightbox body 1, it blocks the delivery port 4, preventing external rainwater from entering through the delivery port 4 and causing water accumulation. By closing the telescopic fixing assembly 5 for telescopic locking, the position of the lightbox body 1 is fixed.

[0024] Reference Figure 3A U-shaped positioning frame 8 is fixedly connected to the back of the inner wall of the light box body 1, and the outer wall of the U-shaped positioning frame 8 is attached to the inner wall of the inner insertion frame 32.

[0025] When advertising paper is placed through the inlet 4, it will fall directly to the bottom of the lightbox body 1 under the influence of gravity, that is, the gap between the inner frame 32 and the inner wall of the lightbox body 1. If the inner frame 32 moves backward at this time, it may cause damage or wrinkles to the advertising paper, and the inner frame 32 will also lose its double sealing effect. Therefore, the U-shaped positioning frame 8 is set to position the placed advertising paper, ensuring that the paper is located inside the inner frame 32 and making it easier to straighten the paper.

[0026] Reference Figure 3 The top of the lightbox body 1 is fixedly connected to a top cover assembly 9, which is opened to cover the delivery port 4.

[0027] By setting the top cover assembly 9, a double sealing effect can be formed on the inlet 4, further preventing water from entering the interior of the light box body 1 through the inlet 4. In addition, it can prevent water from accumulating inside the inlet 4. If the inner frame 32 does not form a barrier to the inlet 4, the water inside the inlet 4 will fall directly into the interior of the light box body 1, causing dampness.

[0028] Reference Figure 2 The outer frame plate 31 has a rubber frame pad 1 on its back, and the inner frame 32 has a rubber frame pad 2 on its back. The outer wall of the inner frame 32 is tightly fitted to the inner wall of the light box body 1.

[0029] This structural design can further enhance the overall sealing effect of the window frame assembly 3 on the light box body 1. Regarding the contact between the inner frame 32 and the inner wall of the light box body 1, in order to avoid gaps between the light box body 1 and the side wall of the inner frame 32, the blocking effect of the inner frame 32 on the delivery port 4 is reduced.

[0030] Reference Figure 4 The telescopic fixing assembly 5 includes a fixed cylindrical shell 51, which is fixedly connected to the inner wall of the column hole 6. A sliding column 52 is slidably sleeved inside the fixed cylindrical shell 51. The sliding column 52 extends through the outside of the fixed cylindrical shell 51. The side wall of the sliding column 52 is fixedly connected to the inner wall of the through hole 7. A threaded hole extending to the back is opened at the front end of the sliding column 52. A threaded rod 53 is threadedly sleeved in the threaded hole. A nut 54 is provided at the back end of the inner wall of the fixed cylindrical shell 51.

[0031] In use, the telescopic fixing assembly 5 can be telescopically extended by sliding the sliding column 52 inside the fixed cylinder shell 51. When the telescopic fixing assembly 5 is in the retracted state, the threaded rod 53 is rotated to move it to engage with the nut 54, so that the threaded rod 53 is screwed into the nut 54, thereby locking the telescopic fixing assembly 5 in a telescopic manner.

[0032] Reference Figure 4 The sliding column 52 includes a slider 521, a central column 522 fixedly connected to the positive end of the slider 521, and a connecting column 523 fixedly connected to the positive end of the central column 522. The diameter of the slider 521 is larger than the diameter of the central column 522. The slider 521 slides inside the fixed cylindrical shell 51, the central column 522 extends through the outside of the fixed cylindrical shell 51, and the connecting column 523 is fixedly connected to the inner wall of the through hole 7.

[0033] The size difference between the slider 521 and the central column 522 can prevent the slider 52 from falling out of the fixed cylindrical shell 51.

[0034] Reference Figure 5 The top cover assembly 9 includes a U-shaped cover 91, which is fixedly connected to the top of the light box body 1. A cover plate body 92 is slidably sleeved on the inner wall of the U-shaped cover 91. Both sides of the cover plate body 92 are provided with protruding posts 93. Both sides of the inner wall of the U-shaped cover 91 are provided with anti-detachment grooves 94, and the protruding posts 93 are slidably sleeved in the anti-detachment grooves 94.

[0035] By pulling the cover body 92, it slides inside the U-shaped cover 91 until the cover body 92 slides out of the U-shaped cover 91 and blocks the inlet 4, thus achieving the effect of sealing the inlet 4. The protruding post 93 and the anti-detachment groove 94 work together to prevent the cover body 92 from falling out of the U-shaped cover 91.

[0036] Reference Figure 5 The top of the cover plate body 92 is provided with a raised strip 95.

[0037] This feature allows for easy pulling of the cover body 92.
