Technical Field
[0001] This utility model belongs to the technical field of advertising light box body, and specifically relates to an outdoor self-heating advertising light box body. Background Technology
[0002] Outdoor advertising light boxes serve as an important carrier for modern urban commercial advertising and information dissemination, and are widely used in public places such as streets, squares, and bus stops. However, in the outdoor environment, advertising light boxes are exposed to natural conditions such as high temperature, sunlight, and wind and rain for a long time, and their heat dissipation performance becomes a key factor affecting stable operation and service life.
[0003] The current announcement is for Chinese utility model patent CN220020560U, which discloses an outdoor lightbox body that facilitates poster replacement. The lightbox body has a protective door hinged to its front by two hinges. A glass observation frame is fixedly embedded in the front of the protective door. This design facilitates the clamping, fixing, and tightening of advertising posters, allowing for quick replacement by staff. The telescopic bracket also facilitates the vertical adjustment of the lightbox body, improving the usability of the outdoor lightbox body.
[0004] This patent only has one heat dissipation vent, relying on natural convection for heat dissipation. Natural convection heat dissipation depends on the natural flow of air to carry away heat, but in high temperature or poor ventilation environments, the heat dissipation efficiency is extremely low, which can easily lead to excessively high internal temperature of the light box body, accelerate the aging of electronic components, and even cause malfunctions. Utility Model Content
[0005] The purpose of this utility model is to provide an outdoor self-heating advertising lightbox body, which solves the problem that existing advertising lightbox bodies rely solely on natural convection for heat dissipation. Natural convection heat dissipation depends on the natural flow of air to remove heat, but in high-temperature or poorly ventilated environments, the heat dissipation efficiency is extremely low, which can easily lead to excessively high internal temperatures of the lightbox body, accelerate the aging of electronic components, and even cause malfunctions.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an outdoor self-heating advertising light box body, including a column, a connecting mechanism on the column, a light box body on the connecting mechanism, and a heat dissipation mechanism inside the light box body.
[0007] The heat dissipation mechanism includes a motor, a first pulley, a first fan, a second pulley, a connecting belt, and a connecting column. The motor is fixedly mounted on the upper surface of the light box body, and the rotating shaft of the motor extends into the interior of the light box body. The first pulley is fixedly mounted on the rotating shaft of the motor. The first fan is fixedly mounted on the first pulley. The second pulley is located inside the light box body and is symmetrically arranged. The connecting belt is located between the first pulley and the second pulley and is used to connect the first pulley and the second pulley. The second fan is fixedly mounted on the lower surface of the second pulley. The upper end of the connecting column is fixedly mounted on the inner top wall of the light box body, and the lower surface of the connecting column is rotatably mounted on the upper surface of the second pulley.
[0008] By adopting the above technical solution, through the setting of a column, a connecting mechanism, a light box body, and a heat dissipation mechanism, in use, the column is first fixed, then the light box body is fixed to the column through the connecting mechanism, and then the heat dissipation mechanism dissipates heat from the inside of the light box body, avoiding heat dissipation through natural convection and improving heat dissipation efficiency. The heat dissipation mechanism includes a motor, a first pulley, a first fan, a second pulley, a connecting belt, a second fan, and a connecting column. When the light box body is in use, the motor first drives the first pulley to rotate, which in turn drives the first fan to rotate. Since the first pulley and the second pulley are connected by a connecting belt, the second pulley can be driven to rotate, which in turn drives the second fan to rotate. The connecting column can fix the second pulley. The rotation of the first fan and the second fan can accelerate the airflow speed inside the light box body, thereby better removing the heat inside the light box body. Compared with the heat dissipation method of natural convection, it can improve the heat dissipation efficiency.
[0009] Furthermore: the connecting mechanism includes a fixed sleeve, a connecting arm, and a connecting plate. The fixed sleeve is disposed on the column, one end of the connecting arm is fixedly disposed on the fixed sleeve by bolts, the connecting plate is fixedly connected to the side wall of the light box body by bolts, and the connecting plate is fixedly disposed on the other end of the connecting arm.
[0010] By adopting the above technical solution, by setting a fixing sleeve, a connecting arm and a connecting plate, the fixing sleeve is set on the column during use, and the light box body is connected to the fixing sleeve through the connecting arm and the connecting plate, thereby fixing the light box body to the column.
[0011] Furthermore: a flow guiding cavity is fixedly installed inside the light box body. The flow guiding cavity has a U-shaped cross-section and an air inlet slot is opened on the flow guiding cavity. The number of air inlet slots is several and evenly arranged. A flow guiding plate is fixedly installed on the side wall of the light box body. The flow guiding plate is arranged corresponding to the air inlet slot.
[0012] By adopting the above technical solution, by setting up a flow guide cavity, an air inlet slot and a flow guide plate, when the first fan and the second fan rotate, the airflow generated can be guided through the flow guide cavity, so that the airflow flows through both sides of the inside of the light box body, and then through the flow guide plate and the air inlet slot to the electrical component position in the middle of the light box body, so as to uniformly dissipate heat from the light box body.
[0013] Furthermore: the column is hollow, and four sliding grooves are provided on the column and arranged symmetrically. A cylinder is fixedly installed at the inner bottom of the column, and a sliding block is fixedly installed on the telescopic shaft of the cylinder. The sliding block can slide inside the column, and a fixing plate is fixedly installed on the sliding block. The fixing plate is fixedly connected to the fixing sleeve through the sliding groove.
[0014] By adopting the above technical solution, by setting a sliding groove, a cylinder, a sliding block and a fixing plate, the column is hollow during use. The cylinder can drive the sliding block to move up and down. Then the sliding block is connected to the fixing sleeve through the fixing plate. In this way, the height of the light box body can be changed by the cylinder. The sliding groove provides the conditions for the vertical movement of the fixing plate.
[0015] Furthermore: a filter plate is fixedly installed on the lower surface of the light box body, and the filter plate has filter holes, which are several and evenly distributed.
[0016] By adopting the above technical solution, and by setting up a filter plate and filter holes, when airflow is generated inside the light box body, the airflow carrying heat is discharged through the filter plate and filter holes. At the same time, the filter holes can prevent impurities from the outside of the light box body from entering the interior of the light box body.
[0017] Furthermore: a rain shield is fixedly installed on the top of the column, the rain shield extends above the light box body, and the rain shield is inclined downward towards the end away from the light box body.
[0018] By adopting the above technical solution and setting up a rain shield, the rain shield can protect the light box body during use, preventing rainwater from falling on the light box body and enabling the light box body to be used in harsh environments.
[0019] Furthermore: a mounting plate is fixedly installed at the lower end of the column, and the mounting plate has four mounting holes arranged symmetrically.
[0020] By adopting the above technical solution, and by setting up an installation plate and installation holes, the installation plate is fixedly connected to the lower surface of the column during use. Through the cooperation of the ground nails and installation holes, the column can be installed on the ground.
[0021] Furthermore, the contact surface between the fixing plate and the sliding groove is smoothly configured.
[0022] By adopting the above technical solution, the contact surfaces of the fixed plate and the sliding groove are smoothly set, which can reduce the friction between the fixed plate and the sliding groove, and make the fixed plate slide better in the sliding groove.
[0023] In summary, this utility model has the following beneficial effects:
[0024] By setting up a heat dissipation mechanism, when the light box body is in use, the motor first drives the first pulley to rotate, which in turn drives the first fan to rotate. Since the first pulley and the second pulley are connected by a connecting belt, the second pulley can be driven to rotate, which in turn drives the second fan to rotate. The second pulley can be fixed by a connecting column. The rotation of the first fan and the second fan can accelerate the airflow speed inside the light box body, thereby better removing the heat inside the light box body. Compared with natural convection heat dissipation, it can improve heat dissipation efficiency.
[0025] By setting up a sliding groove, a cylinder, a sliding block, and a fixing plate, the column is hollow during use. The cylinder can drive the sliding block to move up and down. Then the sliding block is connected to the fixing sleeve through the fixing plate. In this way, the height of the light box body can be changed by the cylinder. The sliding groove provides the conditions for the vertical movement of the fixing plate.
[0026] Based on the above improvements, the overall technical effect achieved by this device is that by designing the first and second fans, the air circulation speed inside the light box body can be increased, thereby better removing the heat inside the light box body. Compared with traditional natural convection heat dissipation, it can significantly improve heat dissipation efficiency. Attached Figure Description

The upper end of the connecting column 407 is fixedly mounted on the inner top wall of the light box body 3, and the lower surface of the connecting column 407 is rotatably mounted on the upper surface of the second pulley 404.
[0037] By setting up a column 1, a connecting mechanism 2, a light box body 3, and a heat dissipation mechanism 4, when in use, the column 1 is first fixed, then the light box body 3 is fixed to the column 1 through the connecting mechanism 2, and then the heat dissipation mechanism 4 dissipates heat inside the light box body 3, avoiding heat dissipation through natural convection and improving heat dissipation efficiency.
[0038] When the lightbox body 3 is in use, the motor 401 first drives the first pulley 402 to rotate, which in turn drives the first fan 403 to rotate. Since the first pulley 402 and the second pulley 404 are connected by a connecting belt 405, the second pulley 404 can be driven to rotate, which in turn drives the second fan 406 to rotate. The second pulley 404 can be fixed by the connecting column 407. The rotation of the first fan 403 and the second fan 406 can accelerate the airflow speed inside the lightbox body 3, which can better remove the heat inside the lightbox body 3. Compared with the natural convection method of heat dissipation, it can improve the heat dissipation efficiency.

The number of air inlet slots 6 is several and evenly arranged. A guide plate 7 is fixedly arranged on the side wall of the light box body 3. The guide plate 7 is arranged corresponding to the air inlet slot 6. By setting the airflow guiding cavity 5, the air inlet slot 6 and the guide plate 7, when the first fan 403 and the second fan 406 rotate, the airflow generated can be guided through the airflow guiding cavity 5, so that the airflow flows through the two sides of the interior of the light box body 3, and then is guided through the guide plate 7 and the air inlet slot 6 to the electrical component position in the middle of the light box body 3, so as to uniformly dissipate heat from the light box body 3.

Thus, the height of the light box body 3 can be changed by the cylinder 9. The sliding grooves 8 provide the conditions for the up and down movement of the fixing plate 11.
[0042] refer to Figure 3 A filter plate 12 is fixedly installed on the lower surface of the light box body 3. The filter plate 12 has filter holes 13. The number of filter holes 13 is several and evenly arranged. By setting the filter plate 12 and filter holes 13, when airflow is generated inside the light box body 3, the airflow carries heat and is discharged through the filter plate 12 and filter holes 13. At the same time, the filter holes 13 can prevent impurities outside the light box body 3 from entering the interior of the light box body 3.

[0046] Brief description of usage:
[0047] In use, the mounting plate 15 is first fixedly connected to the lower surface of the column 1. The column 1 can be installed on the ground through the cooperation of the ground nail and the mounting hole 16. The fixing sleeve 201 is set on the column 1. The light box body 3 is connected to the fixing sleeve 201 through the connecting arm 202 and the connecting plate 203, thereby fixing the light box body 3 to the column 1. Then the column 1 is hollow. The cylinder 9 can drive the sliding block 10 to move up and down. Then the sliding block 10 is connected to the fixing sleeve 201 through the fixing plate 11.
