Description

Technical Field

[0001] This utility model relates to the field of advertising light box technology, specifically an advertising light box with good sealing performance. Background Technology

[0002] In today's commercial society, advertising light boxes are widely used in various corners of cities as an important advertising display medium, such as along streets, inside shopping malls, and in subway stations. With the rapid development of the advertising industry, people's performance requirements for advertising light boxes are also increasing.

[0003] Traditional advertising light boxes have revealed numerous problems over long-term use. Due to their poor sealing, external dust, moisture, and other impurities can easily enter the interior. Dust accumulation adheres to the lighting fixtures and advertising images, affecting not only the clarity and aesthetics of the images and reducing the advertising's effectiveness, but also potentially obstructing the light source and reducing the overall brightness of the light box. This makes it difficult to effectively attract the attention of viewers from a distance or in brightly lit environments. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an advertising light box with excellent sealing performance. It also offers the advantages of easy replacement of advertising posters inside the light box, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a well-sealed advertising light box, comprising a base, a box body fixedly connected to the top of the base, a lamp bracket fixedly connected inside the box body, LED light strips installed on the outer surface of the lamp bracket, a transparent cover plate fixedly connected to the front of the box body by sealant, and a partition plate fixedly connected inside the box body. Side plates are connected to the inner two sides of the box body by screws, and straight grooves and arc grooves are formed on the outer surface of the side plates. A rotating rod is rotatably connected to the outer surface of the side plates. A first crank is fixedly connected to the outer surface of the first rotating rod. A second crank is rotatably connected to one end of the first crank. A second rotating rod is rotatably connected to one end of the second crank. Plate connectors are fixedly connected to both ends of the second rotating rod. A sealing cover is connected to one end of the plate connector by screws. A handwheel is rotatably connected to the back of the box body. A worm gear is fixedly connected to one end of the handwheel, and a worm wheel is driven by the worm gear.

[0008] Preferably, the base and the box are integrally formed, and the top of the box has an opening, and a sealing gasket is provided on the top of the box.

[0009] With the above technical solution, the base and the cabinet are integrally formed from stainless steel, which makes the structure more robust. There are no gaps between the base and the cabinet, so that moisture and dust cannot enter the interior through the gaps between the two. When the sealing cover is closed on the top of the cabinet, the sealing ring set on the top of the cabinet can fit the sealing cover, so it is difficult for external moisture or dust to enter the interior of the cabinet. This can prevent moisture and dust from entering the cabinet and causing a deterioration in the luminous effect.

[0010] Preferably, the worm gear is fixedly connected to the outer surface of the rotating rod, and an L-shaped bracket is fixedly connected to the inner wall of the housing, with one end of the worm gear rotatably connected to the L-shaped bracket.

[0011] Preferably, the straight groove and the arc groove are interconnected, and the plate connector is rotatably connected to the straight groove via a shaft.

[0012] Through the above technical solution, rotating the handwheel drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the first rotating rod to rotate, which in turn drives the first crank to rotate around its axis. The first crank then drives the second crank, which in turn drives the second rotating rod to gradually rise within the straight groove. The shaft of the plate connector also rises within the straight groove. When the shaft of the plate connector touches the top of the straight groove, the end of the second rotating rod is at the junction of the straight groove and the arc groove. At this point, as the first crank continues to rotate, the second crank will drive the second rotating rod to slide into the arc groove. Inside the slot, the rotating rod will then drive the plate connector to rotate around the axis into which it is inserted into the straight slot. This will cause the plate connector to rotate 90 degrees, which in turn will cause the sealing cover to rotate 90 degrees, thereby opening the top of the box. This makes it easy to replace the advertising poster inside the box. The new advertising poster is placed in the gap between the transparent cover and the partition to complete the poster replacement. After the replacement is completed, turning the handwheel in the opposite direction will cause the sealing cover to close again. Furthermore, because the worm gear and worm have a self-locking structure, the sealing cover cannot be opened without turning the handwheel, ensuring the seal.

[0013] Preferably, a support plate is connected to the inside of the base by screws, several battery packs are installed on the top of the support plate, the battery packs are connected to a transformer by wires, and a switch button is installed on the side of the base.

[0014] The above technical solution involves installing a power supply component on the upper surface of the support plate. Several battery packs, along with a transformer, provide power to the LED light strip. The circuit of the LED light strip can be connected via a switch button. When the switch button is turned on, the LED light strip is powered on, generating strong light that reflects inside the box, thus providing a better visual effect for advertising posters.

[0015] Preferably, the bottom of the base is bolted to a base plate, and the lower surface of the base plate is fitted with casters.

[0016] The above technical solution allows the entire lightbox to be easily moved by installing casters on the lower surface of the base plate. Combined with components such as the battery pack, it can provide power for continuous operation, making it convenient for outdoor use. A sealing gasket is also installed between the base plate and the base to ensure the sealing performance of the bottom of the base. A charging port is also provided on the back of the base to charge the battery pack.

[0017] Compared with the prior art, this utility model provides an advertising light box with good sealing performance, which has the following beneficial effects:

[0018] 1. This utility model uses stainless steel to form the base and the box body in one piece, which is sturdy and seamless, and can prevent moisture and dust from entering the interior through the gap between the two. A sealing gasket is set on the top of the box body, which can fit snugly when the sealing cover is closed. In addition, the worm gear and worm form a self-locking structure, and the sealing cover cannot be opened when the handwheel is not turned. Multiple protections ensure that external moisture and dust cannot enter the interior of the box body, so as to avoid affecting the light-emitting effect.

[0019] 2. This utility model allows the sealing cover to be flipped open or closed by rotating the handwheel and using components such as the crank, making it easy to replace advertising posters. At the same time, the base is equipped with power supply components such as battery pack and transformer. Combined with the switch button on the side, it can power the LED light strip to produce strong light for a good visual effect. The bottom of the base is equipped with a base plate with universal wheels, which makes it easy to move the entire light box. It also has a charging port to charge the battery pack, which is beneficial for outdoor use. Attached Figure Description

A second crank 12 is rotatably connected to one end of the first crank 11. A second rotating rod 13 is rotatably connected to one end of the second crank 12. Plate connectors 14 are fixedly connected to both ends of the rotating rod 13. A sealing cover 15 is connected to one end of the plate connector 14 by screws. A handwheel 16 is rotatably connected to the back of the box body 2. A worm gear 17 is fixedly connected to one end of the handwheel 16. A worm wheel 18 is driven by the worm gear 17.

[0030] Specifically, the base 1 and the housing 2 are integrally formed, with an opening at the top of the housing 2 and a sealing gasket at the top. The advantages are that the base 1 and housing 2 are integrally formed from stainless steel, making the structure more robust, and the absence of gaps between them prevents moisture and dust from entering. When the sealing cover 15 is closed on the top of the housing 2, the sealing ring at the top of the housing 2 fits snugly against the sealing cover 15, making it difficult for external moisture or dust to enter the interior of the housing 2. This prevents moisture and dust from entering the housing 2 and causing a deterioration in the luminous effect.

[0031] Specifically, the worm gear 18 is fixedly connected to the outer surface of the rotating rod 10, and an L-shaped bracket 19 is fixedly connected to the inner wall of the housing 2. One end of the worm 17 is rotatably connected to the L-shaped bracket 19. The straight groove 8 and the arc groove 9 are interconnected, and the plate connector 14 is rotatably connected to the straight groove 8 through a shaft. The advantage is that when the handwheel 16 is turned, the worm gear 17 rotates, which in turn drives the worm wheel 18 to rotate. The worm wheel 18 drives the first rotating rod 10 to rotate, which in turn drives the first crank 11 to rotate around the axis of the first rotating rod 10. The first crank 11 then drives the second crank 12, which in turn drives the second rotating rod 13 to gradually rise within the straight groove 8. The shaft of the plate connector 14 also rises within the straight groove 8. When the shaft of the plate connector 14 touches the top of the straight groove 8, the end of the shaft of the second rotating rod 13 is just at the junction of the straight groove 8 and the arc groove 9. At this point, as the first crank 11 continues to rotate, the second crank 12 will drive the second rotating rod 13 to rotate. 3. Slide into the arc groove 9, and then the rotating rod 2 13 will drive the plate connector 14 to rotate around the axis that it is inserted into the straight groove 8.
