[0002] In the field of highway transportation, electronic information displays play a crucial role in the real-time dissemination of traffic information and traffic guidance. With increasingly complex and diverse traffic conditions, higher demands are being placed on the mobility and flexibility of electronic information displays.

[0003] Traditional highway electronic information displays are mostly fixed installations, making them difficult to move. When there are changes in road construction sites, adjustments to temporary traffic control areas, or emergencies requiring the rapid deployment of displays in specific areas, they cannot respond quickly, resulting in untimely information dissemination and affecting traffic management efficiency.

[0004] Furthermore, some existing portable displays suffer from complex operation and low precision in height and angle adjustment, requiring specialized tools and complicated procedures, increasing the workload and deployment time for staff, and failing to meet the needs of efficient and convenient traffic management. At the same time, the installation and dismantling process of the displays is also cumbersome, hindering maintenance and equipment replacement, further limiting their convenience and practicality in real-world applications. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a movable highway electronic information display screen. The limiting plate and limiting block in the limiting component are made of elastic rubber plate. During the snap-fit ​​process, it can generate a certain elastic deformation to adapt to the small errors in the installation and adjustment process, and make the snap-fit ​​tighter and more stable, effectively preventing the display screen from shaking or shifting during use.

[0006] A movable highway electronic information display screen includes a base, on the upper side of which symmetrical support columns are fixed. The support columns are cylindrical and have a set of evenly arranged mounting holes from top to bottom.

[0007] It also includes a mounting plate, with limiting members fixedly connected to the upper and lower ends of the mounting plate. The limiting members are L-shaped. The mounting plate is provided with through holes. After the bolt passes through the mounting holes on the support column and the through holes on the mounting plate, it is threadedly connected with the nut to realize the installation of the support column and the mounting plate.

[0008] It also includes a display screen, the back of which is fixed with symmetrical mounting strips, each of which is provided with symmetrical slots, and each pair of slots is matched with the limiting members fixed at the upper and lower ends of the mounting plate.

[0009] Both the mounting plate and the display screen are connected to limiting components.

[0010] As a further limitation of this technical solution, the limiting component includes a connecting plate, a rotating disk, a limiting plate, and a limiting block. One end of the mounting plate is fixedly connected to the connecting plate. There are two connecting plates arranged symmetrically, and each connecting plate has a notch. One side of the display screen is rotatably connected to the rotating disk. The limiting plate is fixed at the outer middle edge of the rotating disk. The outer end of the limiting plate coincides with the arc-shaped wall of the rotating disk. The limiting blocks are fixed on both sides of the outer end of the rotating disk. One side of the limiting block can abut against the side of the connecting plate located in the notch. The limiting block and the connecting plate are engaged. The limiting plate and the connecting plate are engaged.

[0011] As a further limitation of this technical solution, the rotating disk has a fixed handle at its center.

[0012] As a further limitation of this technical solution, both the limiting plate and the limiting block are made of elastic rubber plates.

[0013] As a further limitation of this technical solution, wheels are respectively provided at the four lower corners of the base.

[0014] As a further limitation of this technical solution, the lower middle part of the support column is fixedly connected to the mounting component, each mounting component is rotatably connected to the first support arm, the first support arm is rotatably connected to one end of the second support arm, the other end of the second support arm is fixedly connected to the support frame, the support frame is fixedly connected to the support plate, and the support plate is provided with a plurality of evenly arranged through holes.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] The base is equipped with self-locking wheels at the four corners, allowing the display screen to be easily moved along the road or in other areas where needed. Whether dealing with emergencies or adjusting the position of the display screen according to changes in traffic flow, it can be quickly positioned.

[0017] A set of evenly arranged mounting holes on the support column are connected to the mounting plate by bolts and nuts. Users can easily loosen the nuts, move the mounting plate up and down and select appropriate mounting holes to fix it according to actual viewing needs and site conditions, so as to achieve precise adjustment of the display screen height and ensure that the information can be clearly displayed to passing drivers, adapting to different road environments and viewing angle requirements.

[0018] The connection between the mounting plate and the support column is firm and stable, ensuring that the display screen can work normally in harsh outdoor environments and is not easily affected by factors such as wind and vibration. The limiting plate and limiting block in the limiting component are made of elastic rubber plate, which can generate a certain elastic deformation during the snap-fit ​​process to adapt to the small errors in the installation and adjustment process, and make the snap-fit ​​tighter and more stable, effectively preventing the display screen from shaking or shifting during use.

[0019] The mounting strip on the back of the display screen and the limiting component on the mounting plate are connected by a slot.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] A movable highway electronic information display screen 1 includes a base 4, on the upper side of which symmetrical support columns 9 are fixed. The support columns 9 are cylindrical and have a set of evenly arranged mounting holes 901 from top to bottom.

[0029] It also includes a mounting plate 12, the upper and lower ends of which are fixedly connected to limiting members 11. The limiting members 11 are L-shaped. The mounting plate 12 is provided with through holes 7. After the bolt passes through the mounting hole 901 on the support column 9 and the through hole 7 on the mounting plate 12, it is threadedly connected with the nut to realize the installation of the support column 9 and the mounting plate 12.

[0030] It also includes a display screen 1, on the back of which symmetrical mounting strips 10 are fixed. Each mounting strip 10 is provided with symmetrical slots 101, and each pair of slots 101 is matched with the limiting members 11 fixed at the upper and lower ends of the mounting plate 12.

[0031] Both the mounting plate 12 and the display screen 1 are connected to limiting components.

[0032] In this embodiment, when it is necessary to adjust the height of the display screen 1, first loosen the bolts and nuts of the mounting plate 12, move the mounting plate 12 up and down along the support column 9 to a suitable position, so that the through hole 7 on the mounting plate 12 is aligned with the corresponding mounting hole 901 on the support column 9, and then tighten the bolts and nuts to fix the mounting plate 12 at the new height position, thereby realizing the adjustment of the height of the display screen 1.

[0033] Specifically, the display screen 1 itself adopts common electronic display technology, such as LED display technology. Its internal control circuit receives information data such as images and text from external signal sources and converts these data into corresponding electrical signals to drive the pixels on the display screen 1 to emit light or change color, thereby forming various visible traffic information patterns and texts to be displayed to passing drivers.

[0034] The limiting assembly includes a connecting plate 13, a rotating disk 14, a limiting plate 15, and a limiting block 16. One end of the mounting plate 12 is fixedly connected to the connecting plate 13. There are two connecting plates 13 arranged symmetrically, and each connecting plate 13 has a notch 131. The rotating disk 14 is rotatably connected to one side of the display screen 1. The limiting plate 15 is fixed at the middle edge of the outer side of the rotating disk 14. The outer end of the limiting plate 15 coincides with the arc-shaped wall surface of the rotating disk 14. The limiting blocks 16 are fixed on both sides of the outer end of the rotating disk 14. One side of the limiting block 16 can abut against the side of the connecting plate 13 located in the notch 131. The limiting block 16 and the connecting plate 13 are engaged. The limiting plate 15 and the connecting plate 13 are engaged.

[0035] The rotating disk 14 has a central fixed handle 141.

[0036] Both the limiting plate 15 and the limiting block 16 are made of elastic rubber.

[0037] In this embodiment, the initial position of the rotating disk 14 is as follows: Figure 4 As shown, at this time, the notch of the rotating disk 14 faces the connecting plate 13, and the rotation of the rotating disk 14 will not interfere with the connecting plate 13. By rotating the handle 141 fixed in the center of the rotating disk 14, the rotating disk 14 is driven to rotate. Since the limiting plate 15 and the limiting block 16 on the outer side of the rotating disk 14 are engaged with the connecting plate 13 on the mounting plate 12, when the rotating disk 14 rotates, the limiting plate 15 and the limiting block 16 will move with the rotating disk 14 and slide in the notch 131 of the connecting plate 13. Thus, under the limitation of the connecting plate 13, they undergo elastic deformation and disengage from the connecting plate 13, so that they are no longer stuck by the connecting plate 13. Then, the display screen 1 can be moved to drive the mounting strip 10 and the limiting plate 13. The relative movement between the positioning components 11 enables the separation of the mounting strip 10 and the limiting component 11, facilitating the disassembly of the display screen 1. When installing the display screen 1, after the mounting strip 10 and the limiting component 11 are engaged, the position of the display screen 1 is adjusted so that the rotating disk 14 at one end aligns with the connecting plate 13. Then, the handle 141 is turned to drive the rotating disk 14 to rotate, which in turn drives the limiting plate 15 and the limiting block 16 to rotate, causing the limiting plate 15 and the limiting block 16 to be locked by the connecting plate 13. During this process, the limiting plate 15 and the limiting block 16 undergo elastic deformation until the limiting block 16 is locked by one side of the notch 131 and the limiting plate 15 is locked by the connecting plate 13, thus limiting the position of the display screen 1.

[0038] There are two limiting components 11, which are located at both ends of the mounting plate 12, and are used to limit the left and right sides of the display screen 1.

[0039] Specifically, the limiting plate 15 and the limiting block 16 are made of elastic rubber plates, which can produce a certain elastic deformation during rotation, making the engagement tighter and more stable.

[0040] The base 4 has wheels 5 at its four lower corners.

[0041] Furthermore, the wheel 5 is a wheel with a self-locking function.

[0042] The lower middle part of the support column 9 is fixedly connected to the mounting component 3. Each mounting component 3 is rotatably connected to the first support arm 8. The first support arm 8 is rotatably connected to one end of the second support arm 17. The other end of the second support arm 17 is fixedly connected to the support frame 18. The support frame 18 is fixedly connected to the support plate 6. The support plate 6 is provided with a plurality of evenly arranged through holes 7.

[0043] A preload is provided between the first support arm 8 and the mounting component 3, and a preload is provided between the first support arm 8 and the second support arm 17, so as to facilitate the adjustment of the position of the support plate 6.

[0044] In this embodiment, if it is necessary to install other auxiliary equipment (such as lighting fixtures, surveillance cameras, etc.) on the support plate 6, or to adjust the position and angle of the support plate 6 according to actual usage requirements, the support structure can be adjusted. The operator first applies appropriate external force to overcome the pre-tightening force between the first support arm 8 and the mounting part 3 and between the first support arm 8 and the second support arm 17, so that the first support arm 8 rotates relative to the mounting part 3 and the second support arm 17 rotates relative to the first support arm 8, thereby driving the support frame 18 and the support plate 6 to move to the required position and angle. After the adjustment is completed, the external force is released. Under the action of the pre-tightening force, each component will remain in the new position, providing a suitable working posture and angle for the equipment installed on the support plate 6.

[0045] In some embodiments, a plurality of reinforcing plates 2 are fixed between the symmetrical support columns 9, and the reinforcing plates 2 are provided with openings to facilitate the installation of other auxiliary equipment.

[0046] The working process of this utility model is as follows:

[0047] Push or pull the base 4 and use the wheels 5 on the underside of the base 4 to move the display screen 1 to the desired position. After reaching the designated position, lock the wheels 5 to prevent it from moving and ensure stability during use.

[0048] Based on the actual site conditions and viewing requirements, determine the appropriate height of the display screen 1, then move the mounting plate 12 up and down along the support column 9, select the appropriate mounting hole 901, align the through hole 7 of the mounting plate 12 with the mounting hole 901 of the support column 9, install the bolts and nuts, and finally tighten the bolts and nuts to complete the height adjustment of the display screen 1.

[0049] Move the display screen 1 to the vicinity of the installed support column 9 and mounting plate 12, aligning the slot 101 on the mounting strip 10 on the back of the display screen 1 with the limiting members 11 at the upper and lower ends of the mounting plate 12. Then, push the display screen 1 smoothly so that the mounting strip 10 is fully inserted into the limiting member 11, initially fixing the position of the display screen 1. Next, manually rotate the handle 141 in the center of the rotating disk 14 to slowly rotate the rotating disk 14, so that the limiting plate 15 and limiting block 16 on the outer side of the rotating disk 14 gradually approach the connecting plate 13 on the mounting plate 12. During the rotation, since the limiting plate 15 and limiting block 16 are made of elastic rubber, they will undergo a certain elastic deformation. When rotated to the appropriate position, the limiting plate 15 will be inserted between the connecting plates 13, and the limiting block 16 will be inserted into the recess 131 of the connecting plate 13. Under the action of elastic restoring force, the display screen 1 and the mounting plate 12 are tightly connected and limited, completing the installation process of the display screen 1 and ensuring that the display screen 1 can work stably and reliably in subsequent use and display traffic information normally.

[0050] The limiting plate 15 and the limiting block 16 can also be made of aluminum alloy material with a certain degree of elasticity, which is stronger and safer.

[0051] When maintenance, repair, or replacement of display screen 1 is required, first stand to one side of display screen 1 and turn the handle 141 in the center of the rotating disk 14 by hand to make the rotating disk 14 rotate in the opposite direction, causing the limiting plate 15 and the limiting block 16 to disengage from the connecting plate 13. During the rotation, you will also feel the elastic deformation of the limiting plate 15 and the limiting block 16. After the limiting plate 15 and the limiting block 16 are completely disengaged from the connecting plate 13, grasp the edge of display screen 1 and pull display screen 1 outward along the groove 101 of the mounting strip 10 and the limiting member 11 to separate the mounting strip 10 from the limiting member 11. Then display screen 1 can be removed from the mounting plate 12 for subsequent operations.

[0052] If it is necessary to install other auxiliary equipment (such as lighting fixtures, surveillance cameras, etc.) on the support plate 6, or to adjust the position and angle of the support plate 6 according to actual usage needs, the support structure can be adjusted. The above-disclosed embodiments are only specific embodiments of this utility model; however, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
