Description

Technical Field

[0001] This invention relates to the field of advertising display devices, and more particularly to an advertising light box. Background Technology

[0002] Advertising light boxes are boxes with an internal light source and advertising posters pasted on their interior or surface. They are widely used in shopping malls, barbershops, beauty salons, train stations, highway toll stations, parking lots, hotels, entertainment venues, banks, photo studios, and other places.

[0003] The LEDs inside existing advertising light boxes generate heat after prolonged use, so heat dissipation holes are made on the light box for heat dissipation. However, in some outdoor use scenarios, rain and snow can enter the light box through the heat dissipation holes, causing damage to the light box and making it inconvenient to use. Summary of the Invention

[0004] This invention proposes an advertising light box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An advertising lightbox includes a protective shell with an internal accommodating space. A sliding frame is vertically installed at the corners of the protective shell. A sliding plate is slidably installed within the sliding frame. A connecting plate is fixedly installed on each opposite surface of the sliding plate. The connecting plate is slidably installed on a groove on the opposite surface of the sliding frame. A receiving plate is fixedly installed on the connecting plate via a connecting assembly. A lightbox body is fixedly installed on the receiving plate. A rainproof top cover is fixedly installed on the top of the lightbox body. A sealing ring at the bottom of the rainproof top cover mates with an opening at the top of the protective shell. A power assembly for controlling the sliding plate is rotatably installed within the protective shell below the receiving plate. The power assembly includes a first motor, a worm gear, a worm wheel, a rotating shaft, a mounting base, a lever, and a fork-shaped head. A mounting base is fixedly installed within the protective shell. Rotating shafts are symmetrically rotatably installed on the mounting base. A worm wheel is fixedly installed in the middle of the rotating shaft. A worm gear driven by the first motor meshes between the two worm wheels. Lever plates are fixedly installed at both ends of each rotating shaft. The lever plates are slidably connected to the bottom of the corresponding sliding plate via fork-shaped heads.

[0006] A further preferred embodiment of the present invention: the connecting assembly includes a cam, a second motor, push rods, and springs. The second motor drives the cam to cooperate with the push rods on both sides. The push rods are U-shaped, and the two sides of the open end of the push rods are slidably mounted on the connecting plate. Each open end is fitted with a spring on both sides. The two push rods that are farther apart on each connecting plate are fixedly connected to the scraper, and the two push rods that are closer together on each connecting plate are connected to the insertion port on the side of the receiving plate.

[0007] A further preferred embodiment of the present invention: heat dissipation holes are provided on the top side of the light box body, an upper concave plate is fixedly installed on the top outer side of the heat dissipation hole, and a lower inner inclined plate is fixedly installed on the bottom inner side of the heat dissipation hole.

[0008] A further preferred embodiment of the present invention: a heat dissipation mesh that matches the heat dissipation holes is fixedly installed on the inner side of the top of the light box body.

[0009] A further preferred embodiment of the present invention: an air inlet is provided at the bottom of the protective shell, an air inlet pipe is fixedly installed on the air inlet, the air inlet pipe is in the shape of an inverted bottle, the top diameter of the air inlet pipe is larger than the bottom diameter of the air inlet pipe, and a skirt plate is fixedly installed on the outside of the air inlet pipe, the skirt plate being adapted to the top diameter of the air inlet pipe.

[0010] A further preferred embodiment of the present invention: a support leg is fixedly installed at the bottom corner of the receiving plate, the support leg is rectangularly distributed, and the bottom surface of the support leg is in contact with the inner wall of the bottom of the protective shell.

[0011] The present invention has the following advantages: 1. This invention provides a rainproof top cover on the top of the light box body. The sealing ring at the bottom of the cover precisely matches the opening at the top of the protective shell to form a sealed protection, which can effectively prevent rain and snow from entering through the gaps at the top of the light box. This significantly improves the stability of the light box in complex outdoor weather conditions, extends the overall service life of the equipment, and reduces maintenance costs.

[0012] 2. This invention utilizes heat dissipation holes on the top side of the lightbox body, along with an upper concave plate, a lower inner inclined plate, and a heat dissipation mesh, to ensure air circulation between the inside of the lightbox and the outside while providing protection against rain and snow. Simultaneously, an air inlet is located at the bottom of the protective shell, and the matching air inlet duct is designed in an inverted bottle shape, with a larger top diameter than a bottom diameter. This structure promotes natural air convection, allowing cold outside air to enter the protective shell through the air inlet duct and then exit through the heat dissipation holes of the lightbox, forming a complete heat dissipation cycle. This effectively removes the heat generated by the light source during prolonged operation, preventing problems such as lamp chip damage and reduced luminous efficiency due to overheating, and ensuring long-term stable operation of the lightbox. Furthermore, the skirt plate outside the air inlet duct is adapted to the top diameter of the air inlet duct to prevent rain and snow from entering through the air inlet, further improving the protective effect.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0015] according to Figure 1-3 As shown, an advertising lightbox includes a protective shell 1 with an internal accommodating space. A sliding frame 2 is vertically installed at the corners of the protective shell 1. A sliding plate is slidably installed inside the sliding frame 2. A connecting plate 19 is fixedly installed on each opposite surface of the sliding plate. The connecting plate 19 is slidably installed on a groove 3 on the opposite surface of the sliding frame 2. A receiving plate 4 is fixedly installed on the connecting plate 19 via a connecting assembly. A lightbox body 10 is fixedly installed on the receiving plate 4. A rainproof top cover 11 is fixedly installed on the top of the lightbox body 10. The sealing ring at the bottom of the rainproof top cover 11 is connected to the opening at the top of the protective shell 1. In conjunction with this, a power assembly for controlling the skateboard is rotatably installed inside the protective shell 1 below the receiving plate 4. The power assembly includes a first motor 9, a worm gear 7, a worm wheel 8, a rotating shaft, a mounting base 12, a lever 6, and a fork-shaped head 5. The mounting base 12 is fixedly installed inside the protective shell 1. A rotating shaft is symmetrically rotatably installed on the mounting base 12. A worm wheel 8 is fixedly installed in the middle of the rotating shaft. A worm gear 7 driven by the first motor 9 is meshed between the two worm wheels 8. A lever 6 is fixedly installed at both ends of each rotating shaft. The lever 6 is slidably connected to the bottom of the corresponding skateboard through the fork-shaped head 5.

[0016] The connecting assembly includes a cam 20, a second motor, push rods 21, and springs 22. The second motor drives the cam 20 to cooperate with the push rods 21 on both sides. The push rods 21 are U-shaped, and the two sides of the open end of the push rod 21 are slidably mounted on the connecting plate 19. Springs 22 are fitted on both sides of each open end. The two push rods 21 that are farther apart on each relative connecting plate 19 are fixedly connected to the scraper 23, and the two push rods 21 that are closer together on each relative connecting plate 19 are connected to the side sockets of the receiving plate 4. This arrangement ensures that the second motor drives the cam 20 to control different push rods 21.

[0017] The top and sides of the lightbox body 10 are provided with heat dissipation holes. An upper concave plate 18 is fixedly installed on the outer top of the heat dissipation hole, and a lower inner inclined plate 17 is fixedly installed on the inner bottom of the heat dissipation hole, so as to ensure heat dissipation and reduce the possibility of rainwater entering.

[0018] A heat dissipation mesh 16 that matches the heat dissipation holes is fixedly installed on the inner side of the top of the light box body 10. This arrangement ensures that no impurities will enter the interior of the light box body 10.

[0019] The protective shell 1 has an air inlet at the bottom, and an air inlet pipe 14 is fixedly installed on the air inlet. The air inlet pipe 14 is in the shape of an inverted bottle. The top diameter of the air inlet pipe 14 is larger than the bottom diameter of the air inlet pipe 14. A skirt plate 15 is fixedly installed on the outside of the air inlet pipe 14. The skirt plate 15 is adapted to the top diameter of the air inlet pipe 14.

[0020] Support legs 13 are fixedly installed at the bottom corner of the receiving plate 4. The support legs 13 are rectangularly distributed, and the bottom surface of the support legs 13 is in contact with the bottom inner wall of the protective shell 1. This arrangement can ensure the stability of the receiving plate 4 after it is separated from the connecting plate 19.

[0021] Working principle: When rain or snow occurs, the first motor 9 is started. The output shaft of the first motor 9 drives the worm gear 7 to rotate. Since the worm gear 7 meshes with the two worm wheels 8, the rotation of the worm gear 7 will drive the worm wheels 8 on both sides to rotate synchronously, thereby driving the rotating shaft fixedly connected to the worm wheels 8 to rotate. The lever plates 6 at both ends of the rotating shaft rotate synchronously with the rotating shaft. The lever plates 6 are slidably connected to the bottom of the slide plate through the fork head 5. The rotation of the lever plates 6 is converted into the vertical sliding of the slide plate along the sliding frame 2. The slide plate drives the connecting plate 19 fixed to it to rise and fall synchronously. The connecting plate 19 drives the receiving plate 4 and the light box body 10 to descend into the protective shell 1 together through the connecting component. The sealing ring at the bottom of the rainproof top cover 11 is sealed with the top opening of the protective shell 1 to ensure waterproof performance. At this time, the first motor 9 is turned off and the second motor is started. The cam 20 rotates and drives the push rod 21 to push out the scraper 23. The scraper 23 is engaged with the inner wall of the protective shell 1, and the receiving plate 4 is separated from the connecting plate 19. The second motor is turned off and the first motor 9 is started again to scrape off the condensate inside the protective shell 1.
