Technical Field
[0001] This utility model relates to the field of information boards, specifically a convenient suspended information board. Background Technology
[0002] Information boards are tools used to display and transmit various types of intelligence information. They are commonly found in military, commercial, transportation, and public safety fields. They come in two forms: physical and electronic. The former are often large displays or bulletin boards in specific locations, while the latter exist as software systems that can be accessed through terminals. When designing information boards, attention should be paid to the accuracy and relevance of the content, its visual presentation, and its reasonable layout. Its implementation relies on data collection, transmission, processing, analysis, display, and interaction technologies. The aim is to present complex intelligence intuitively and help relevant personnel make quick decisions.
[0003] The most common portable suspended information boards used in the transportation sector typically consist of a trailer, an electric lifting gate, and a display screen. Placed on highways, urban expressways, or roadsides, they can ensure travel safety in adverse weather conditions, accidents, and other situations. By guiding traffic flow through real-time traffic conditions, they can also improve the travel efficiency of passengers and drivers, making them a key facility for ensuring smooth and safe traffic.
[0004] However, a common type of portable suspended information board on the market has certain problems in use. When the display screen is raised by an electric lifting rod on the side of the highway, the screen is raised vertically, and the contact area with the airflow is large. Due to air resistance, the lifting process will cause strong shaking, which can easily cause the bolts to loosen and greatly increase the risk of equipment damage. Therefore, further improvements are needed. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a convenient suspended information board to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient suspended information board, comprising a device body, a display screen, and an electric lifting rod. The electric lifting rod is rotatably mounted on the top of the device body, and the display screen is rotatably mounted on the end of the electric lifting rod. A support column is fixedly mounted on the top of the device body, and a rotating shaft fixedly connected to the outer wall of the display screen is slidably mounted on the outer wall of the support column. A slider is fixedly mounted on the end of the rotating shaft. A rack and a support block are fixedly mounted on the outer wall of the support column. A gear meshing with the rack is fixedly mounted on the outer wall of the rotating shaft. A first sliding groove, a second sliding groove, and a limiting groove are provided on the outer wall of the support column.
[0007] By adopting the above technical solution, the display screen remains parallel to the ground throughout its lifting and lowering process, greatly reducing the contact area with air and thus effectively reducing wind resistance during lifting and lowering. The reduction in wind resistance fundamentally eliminates the possibility of the display screen swaying during lifting and lowering, providing a solid guarantee for the stable operation of the entire device. At the same time, the support column, as the main support component, further enhances the stability of the display screen when it is raised, making it safer and more reliable during use. By setting up a rack, gear, and second slide, the display screen can be flipped to the normal use state after rising to a certain height. The support block provides support when the display screen is retracted, and the rubber outer wall effectively prevents any damage to the outer wall of the display screen.
[0008] Furthermore, the bottom of the support column is triangular, and two sets of support columns are symmetrically arranged on the top of the main body of the device, with the distance between the two sets of support columns being greater than the length of the display screen.
[0009] By adopting the above technical solution, the support column further enhances the stability of the display screen when it is raised, making it safer and more reliable during use.
[0010] Furthermore, the rotating shaft is symmetrically arranged at the center positions on both sides of the display screen, the slider has a rectangular cross-section, and the width of the slider is smaller than the outer diameter of the rotating shaft.
[0011] By adopting the above technical solution, the display screen is not restricted by the slider when it is flipped.
[0012] Furthermore, the rack is located on the outer wall of the support column near the display screen, and the length of the rack is set to correspond to the rotation range of the gear, and the rotation range of the gear is 0°-90°.
[0013] By adopting the above technical solution, the display screen can be rotated 90° through the interaction of gears and racks.
[0014] Furthermore, the first slide groove is provided corresponding to the end of the rotating shaft, and the length of the first slide groove corresponds to the lifting range of the display screen, and the limiting groove is provided corresponding to the slider.
[0015] By adopting the above technical solution, the lifting and lowering process of the display screen becomes more stable and smooth.
[0016] Furthermore, the length of the second slide groove corresponds to the length of the rack, and the width of the second slide groove is greater than the width of the limiting groove, and the limiting groove is connected to the first slide groove.
[0017] By adopting the above technical solution, the display screen can be flipped without obstruction.
[0018] Furthermore, two sets of support blocks are symmetrically arranged on the outer wall of the support column, and the top outer wall of the support block is in contact with the bottom outer wall of the display screen, and the outer wall of the support block is made of rubber.
[0019] By adopting the above technical solution, the support block can provide support when the display screen is retracted, and the rubber outer wall can effectively prevent damage to the outer wall of the display screen.
[0020] In summary, the present invention has the following main advantages:
[0021] This invention, by incorporating a support column, rotating shaft, slider, first sliding groove, and limiting groove, ensures that the display screen remains parallel to the ground during lifting and lowering, significantly reducing the contact area with air and thus effectively lowering wind resistance during the lifting and lowering process. This reduced wind resistance fundamentally eliminates the possibility of the display screen swaying during lifting and lowering, providing a solid guarantee for the stable operation of the entire device. Simultaneously, the support column, as the main supporting component, further enhances the stability of the display screen when raised, making it safer and more reliable during use. The inclusion of a rack, gear, and second sliding groove allows the display screen to flip back to its normal operating state after rising to a certain height. The support block provides support when the display screen is retracted, and the rubber outer wall effectively prevents damage to the display screen's outer surface. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0029] The embodiments of this utility model will be described below based on its overall structure.
[0030] A convenient suspended information board, such as Figure 1 - Figure 5 As shown, the device includes a main body 1, a display screen 2, and an electric lifting rod 3. The electric lifting rod 3 is rotatably mounted on the top of the main body 1, and the display screen 2 is rotatably mounted on the end of the electric lifting rod 3. A support column 4 is fixedly mounted on the top of the main body 1, and a rotating shaft 21, which is fixedly connected to the outer wall of the display screen 2, is slidably mounted on the outer wall of the support column 4. A slider 23 is fixedly mounted on the end of the rotating shaft 21. A rack 5 and a support block 6 are fixedly mounted on the outer wall of the support column 4. A gear 22, which meshes with the rack 5, is fixedly mounted on the outer wall of the rotating shaft 21. The outer wall of the support column 4 has a first sliding groove 41, a second sliding groove 42, and a limiting groove 43, ensuring that the display screen 2 remains parallel to the ground during its lifting and lowering process, maximizing its stability. By reducing the contact area with air, the wind resistance encountered during the lifting and lowering process is effectively reduced. The reduction in wind resistance fundamentally eliminates the possibility of the display screen 2 shaking during lifting and lowering, providing a solid guarantee for the stable operation of the entire device. At the same time, the support column 4, as the main support component, further enhances the stability of the display screen 2 when it is raised, making it safer and more reliable during use. By setting the rack 5, gear 22 and the second slide 42, the display screen 2 can be flipped to the normal use state after rising to a certain height. By setting the support block 6, the support block 6 provides support when the display screen 2 is retracted, and the rubber outer wall can effectively prevent any damage to the outer wall of the display screen 2.
[0031] Please see Figure 1 - Figure 5 The bottom of the support column 4 is triangular, and two sets of support columns 4 are symmetrically arranged on the top of the main body 1 of the device. The distance between the two sets of support columns 4 is greater than the length of the display screen 2, which further enhances the stability of the display screen 2 when it is raised, making it safer and more reliable during use.
[0032] Please see Figure 3 and Figure 4 The rotating shaft 21 is symmetrically arranged at the center positions on both sides of the display screen 2. The slider 23 has a rectangular cross-section and the width of the slider 23 is smaller than the outer diameter of the rotating shaft 21, so that the display screen 2 is not restricted by the slider 23 when it is flipped.
[0033] Please see Figure 3- Figure 5 The rack 5 is located on the outer wall of the support column 4 near the display screen 2, and the length of the rack 5 is set to correspond to the rotation range of the gear 22. The rotation range of the gear 22 is 0°-90°, so that the display screen 2 can be rotated 90° through the cooperation of the gear 22 and the rack 5.
[0034] Please see Figure 1 - Figure 5 The first slide groove 41 is provided corresponding to the end of the rotating shaft 21, and the length of the first slide groove 41 corresponds to the lifting range of the display screen 2. The limiting groove 43 is provided corresponding to the slider 23, so that the lifting process of the display screen 2 is more stable and smooth.
[0035] Please see Figure 3 - Figure 5 The length of the second slide groove 42 corresponds to the length of the rack 5, and the width of the second slide groove 42 is greater than the width of the limiting groove 43. The limiting groove 43 is connected to the first slide groove 41, so that the display screen 2 will not be obstructed when it is flipped.
[0036] Please see Figure 1 - Figure 5 Two sets of support blocks 6 are symmetrically arranged on the outer wall of the support column 4. The top outer wall of the support block 6 is in contact with the bottom outer wall of the display screen 2. The outer wall of the support block 6 is made of rubber, so that the support block 6 can provide support for the display screen 2 when it is folded up. The rubber outer wall can effectively prevent damage to the outer wall of the display screen 2.
[0037] The working principle of this utility model is as follows: First, the main body 1 of the device is moved to a predetermined suitable position. Then, the electric lifting rod 3 is started. The electric lifting rod 3 starts to work and drives the display screen 2 to rise slowly. During this process, the rise of the display screen 2 will cause the rotating shaft 21 and the slider 23 connected to it to slide upward along the outer wall of the support column 4. When the display screen 2 rises to the position where the gear 22 and the rack 5 just mesh, the slider 23 is exactly at the second slide groove 42. As the electric lifting rod 3 continues to operate, the display screen 2 continues to rise. Due to the interaction between the gear 22 and the rack 5, the display screen 2 will undergo a 90° flipping action, changing from the initial state to a state perpendicular to the bottom surface. The display screen 2 continues to rise until the slider 23 slides to the top position of the limiting groove 43. At this time, the slider 23 is restricted by the limiting groove 43, and the angle of the display screen 2 is also fixed. At the same time, the electric lifting rod 3 stops working, and the display screen 2 rises stably, completing the entire lifting operation.
[0038] When it is necessary to retract the display screen 2, the electric lifting rod 3 is activated again, and the display screen 2 begins to descend. At this time, the slider 23 and the rotating shaft 21 slide down along the outer wall of the support column 4 under the drive of the electric lifting rod 3. When it descends to the point where the gear 22 and the rack 5 contact each other again, the display screen 2 will rotate 90° again under the meshing action of the gear 22 and the rack 5, turning into a state parallel to the ground. The display screen 2 continues to descend until its bottom outer wall is tightly attached to the top outer wall of the support block 6. At this time, the electric lifting rod 3 stops working, the display screen 2 is successfully retracted, and the entire device returns to its initial state for subsequent movement or reuse.
