Description

Technical Field

[0001] This utility model relates to the field of light box heat dissipation technology, and more specifically to a ventilation and heat dissipation mechanism for a tag light box. Background Technology

[0002] Hanging light boxes utilize advanced lighting technology, such as LED light sources, providing concentrated and uniform light that simulates realistic colors, resulting in more lifelike images and excellent visual effects. They attract attention in various environments. Typically suspended, they don't occupy much floor or wall space, making them ideal for space-constrained locations such as shopping malls and subway stations. They effectively display information without obstructing traffic or use. In addition to displaying advertising content, existing hanging light boxes can also be used for navigation and direction finding, such as indicating the location of different areas in shopping malls, providing directional information for travelers in transportation hubs, and displaying corporate culture and meeting agendas in office environments.

[0003] For example, a hanging lightbox with the prior art publication number CN208077557U allows the lightbox to be used for hanging by installing connecting screws and other components on the frame, thus solving the problem of the obvious space occupation of existing lightboxes, and without losing the function of the lightbox for advertising. The advertising information can be updated by replacing the film printed with the advertising information.

[0004] However, the existing technology described above still has the following problems in use: During prolonged operation, the LED display inside the tag lightbox generates heat, which can easily lead to overheating and damage to the LED display. Traditional methods of heat dissipation via ventilation holes are ineffective. Therefore, this invention provides a highly efficient ventilation and heat dissipation mechanism for tag lightboxes. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a ventilation and heat dissipation mechanism for a light box. It draws in outside air through a cooling fan at the bottom of the box and extracts heat from the box through a cooling fan at the top. The bottom-to-top airflow design efficiently accelerates air circulation, significantly enhancing heat dissipation performance, thereby effectively extending the lifespan of the light box and improving operational stability. Furthermore, a metal heat-conducting plate and heat dissipation fins are added to conduct heat, complementing the airflow design and further strengthening the heat dissipation effect, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ventilation and heat dissipation mechanism for a tag light box, comprising a tag light box body, wherein the outer wall of the tag light box body has multiple mounting openings arranged in a circular array, and a light box is fixedly installed inside each mounting opening; a top plate and a bottom plate are respectively installed on the top and bottom of the tag light box body, and ventilation holes are provided on the top plate and the bottom plate; a cooling fan is fixedly installed at the bottom of the top plate and the top of the bottom plate; and a number of metal heat-conducting plates, the same as the number of light boxes, are fixedly installed inside the tag light box body, with the multiple metal heat-conducting plates contacting the inner walls of the multiple light boxes respectively; and multiple equally spaced heat dissipation fins are fixedly installed on the side of each metal heat-conducting plate away from the light box.

[0007] In a preferred embodiment, both the top plate and the bottom plate have tapered cross-sections. The ventilation hole includes a circular hole and multiple rectangular openings connected to each other. The multiple rectangular openings are arranged in a ring array on the outer wall of the top plate and the outer wall of the bottom plate. The cooling fan is located outside the circular hole.

[0008] In a preferred embodiment, each ventilation hole is equipped with a filter screen, which can block external dust and impurities and prevent dust and impurities from affecting heat dissipation.

[0009] In a preferred embodiment, the top of the top plate and the bottom of the bottom plate are provided with a plurality of mounting holes arranged in a circular array. Each mounting hole is provided with a fastening bolt. The top plate and the bottom plate are detachably fixed to the main body of the hanging light box by fastening bolts. The fastening bolt fixing method makes it easy for staff to quickly disassemble the top plate and the bottom plate for cleaning and replacement.

[0010] In a preferred embodiment, rubber sealing strips for filling gaps are provided between the top plate and the bottom plate and the main body of the hanging light box. The rubber sealing strips are located on the outside of multiple fastening bolts. The rubber sealing strips can improve the sealing between the top plate, the bottom plate and the main body of the hanging light box, and prevent dust and impurities from entering the interior of the hanging light box from the gaps.

[0011] In a preferred embodiment, a fixing plate is fixedly provided on the top of the outer wall of the tag light box body, and the fixing plate has a plurality of fixing holes arranged in a circular array on the top for mounting the tag light box body.

[0012] In a preferred embodiment, a wiring hole is provided at the bottom rear end of the main body of the tag light box. The wiring hole is located below the mounting opening, and a rubber plug is provided inside the wiring hole. By using the rubber plug to cover the wire, the sealing between the wire and the wiring hole can be improved to a certain extent.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses a cooling fan at the bottom of the inner cavity of the tag light box to draw in outside air and a cooling fan at the top to extract the heat accumulated inside the box. This bottom-up airflow design can efficiently accelerate air circulation, greatly enhance the heat dissipation performance of the tag light box, thereby effectively extending the life of the tag and improving operational stability. In addition, a metal heat-conducting plate and heat dissipation fins are added to quickly conduct the heat generated by the tag to the tag light box, which works in conjunction with the airflow design to further enhance the heat dissipation effect.

[0015] 2. By designing the top and bottom plates as cones, dust and impurities can slide off the filter surface naturally under gravity, thereby reducing the impact of dust accumulation on airflow to a certain extent. Attached Figure Description

Cooling fans 7 are fixedly installed at the bottom of the top plate 4 and the top of the bottom plate 5. The tag light box body 1 has metal heat-conducting plates 8 with the same number as the light signs 3 fixedly installed inside. Multiple metal heat-conducting plates 8 are in contact with the inner walls of multiple light signs 3 respectively. Multiple heat dissipation fins 9 are fixedly installed on the side of each metal heat-conducting plate 8 away from the light sign 3.

[0026] Both the top plate 4 and the bottom plate 5 have tapered cross sections. The ventilation holes 6 include a circular hole 61 and multiple rectangular openings 62 connected to each other.

[0030] The top plate 4 and bottom plate 5 are each provided with a rubber sealing strip 12 for filling the gaps between them and the main body 1 of the hanging light box. The rubber sealing strip 12 is located on the outside of multiple fastening bolts 11. The rubber sealing strip 12 can improve the sealing between the top plate 4, bottom plate 5 and the main body 1 of the hanging light box, and prevent dust and impurities from entering the interior of the main body 1 of the hanging light box from the gaps.

[0031] In addition, a wiring hole 15 is provided at the bottom rear end of the main body 1 of the tag light box. The wiring hole 15 is located below the mounting port 2.
