[0001] This utility model relates to the field of information display device technology, specifically a visual command and dispatch display device. Background Technology

[0002] In today's rapidly developing social environment, various command and dispatch work involves a wide range of fields, including but not limited to emergency rescue, traffic control, and large-scale event organization. In these scenarios, visual command and dispatch display devices play a key role. They can intuitively present various information and help commanders make accurate decisions. At the same time, in order to meet the needs of "panoramic and integrated" information viewing in large-scale command and dispatch, multi-screen splicing and collaborative display are usually required.

[0003] However, existing visual command and dispatch display devices have revealed some problems that cannot be ignored in practical applications; First, the lack of portability of traditional display devices causes numerous inconveniences in practical use. Many command and dispatch operations are temporary and mobile, such as the establishment of temporary outdoor command posts, which requires the rapid relocation of display devices to different locations. However, traditional display devices are bulky, structurally fixed, and difficult to disassemble or move, making transportation complex and costly in terms of manpower and resources. This not only increases time costs but may also delay command and dispatch operations due to the inability to deploy them in a timely manner, thus reducing the response speed to emergencies.

[0004] Furthermore, traditional display devices lack adequate protection for the display screen during storage and transportation. As the core component of the device, the display screen is constantly exposed to the external environment, making it susceptible to damage from dust, impacts, and other factors, affecting its display quality and lifespan. Moreover, when not in use, traditional display devices lack reasonable storage methods; the display screens cannot be effectively stacked to reduce space occupation, resulting in wasted storage and transportation space and increased storage and transportation costs.

[0005] To address these issues, we have provided a visual command and dispatch display device. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-7 As shown, this utility model provides a technical solution: a visual command and dispatch display device, including multiple display screens 1. The rear end of each display screen 1 has a heat dissipation slot and a data cable interface. The display screen 1 is connected to the control terminal via a data cable. The display screen 1 is the core display component of the device, responsible for receiving and displaying various information from the control terminal, including but not limited to maps, data reports, video surveillance images, etc., to provide command and dispatch personnel with intuitive visual information and assist them in making accurate decisions.

[0022] Multiple movable support frames 2 are provided at the lower end of the display screen 1. The lower end of the movable support frame 2 is connected to a self-locking universal wheel 7. The movable support frame 2 provides a stable support structure for the entire device, and the self-locking universal wheel 7 connected to its lower end gives the device the flexibility to move, enabling the device to be easily transferred between different sites, meeting the site adaptability requirements of command and dispatch work.

[0023] The upper end of the movable support frame 2 is connected to the track frame 3. One end of the track frame 3 is provided with a connecting groove 8, and the other end is connected with a connecting block 9. The size of the connecting block 9 is such that it can be inserted into the connecting groove 8. The upper end of the connecting groove 8 and the connecting block 9 are provided with corresponding connecting holes 10. The track frame 3 is used to provide a moving track for the movable block 4 and limit the moving direction of the movable block 4, so that the display screen 1 can be adjusted along the track frame 3. At the same time, through the design of the connecting groove 8 and the connecting block 9, multiple track frames 3 can be quickly connected together to achieve the rapid connection of multiple track frames 3. By using bolts to pass through the connecting holes 10, two track frames 3 can be quickly connected together.

[0024] A movable block 4 is provided at the lower end of the display screen 1. The movable block 4 is located inside the track frame 3. A roller 5 is connected to the lower end of the movable block 4. The roller 5 is rotatably connected inside the track frame 3. The movable block 4 moves inside the track frame 3 through the roller 5, thereby adjusting the position of the display screen 1 at the upper end of the track frame 3.

[0025] The lower end of the display screen 1 is connected to a rotating shaft 6, which is rotatably connected to the movable block 4. A high-precision bearing is provided between the rotating shaft 6 and the movable block 4, so that the display screen 1 can rotate.

[0026] Multiple movable support frames 2 and track frames 3 can be quickly connected together. Multiple display screens 1 can move within the track frame 3 under the action of the movable block 4. The display screens 1 can rotate on the upper part of the movable block 4, so that multiple display screens 1 can be arranged in a row to splice them into a large display screen, which facilitates rapid deployment. When the device is not in use, by adjusting the angle of the display screens 1, all the display screens 1 can be made parallel to each other. Then, the movable block 4 can drive the display screens 1 to move, stacking all the display screens 1 together, with the rear back panels of the two outermost display screens 1 facing outward. This not only reduces the space occupied by the display screens 1, making storage and transportation convenient, but also avoids the screens of the display screens 1 being exposed. It also makes it easy to use dust covers to cover all the stacked display screens 1 for protection.

[0027] The rear end of the movable block 4 is connected to a support plate 11, which is L-shaped. Its side end is located at the rear end of the track frame 3. The side end of the support plate 11 is connected to a threaded tube 12. The threaded tube 12 is internally threaded with a fixing bolt rod 13. One end of the fixing bolt rod 13 is connected to a rotating handle, and the other end is rotatably connected to a fixing plate 14. The fixing plate 14 can be connected to the outer end of the track frame 3. The fixing bolt rod 13 can be easily rotated by rotating the handle. The rotation of the fixing bolt rod 13 and the threaded tube 12 will push the fixing plate 14 to move. The fixing plate 14 is pressed against the surface of the track frame 3, which can fix the position of the movable block 4, thereby fixing the position of the display screen 1 on the upper end of the movable block 4. The surface of the fixing plate 14 is provided with anti-slip grooves, which can increase the friction between the fixing plate 14 and the track frame 3, making the fixation more secure.

[0028] The upper end of the movable block 4 is provided with a constraint groove 15, and a plug plate 16 is inserted into the constraint groove 15. A handle is connected to one side of the upper end of the plug plate 16, and a constraint strip 17 is connected to the other side. The constraint strip 17 is a sponge strip or a rubber strip, which can be connected to the rear end of the display screen 1. When the display screen 1 is arranged in a line, the plug plate 16 is inserted into the constraint groove 15. At this time, the constraint strip 17 will be connected to the back panel of the display screen 1, so as to determine the angle of the display screen 1 and prevent it from rotating.

[0029] Working principle: When setting up the device, use the self-locking casters 7 at the lower end of the mobile support frame 2 to move the device to a suitable position, step on the brake pedal of the self-locking casters 7 to fix it in that position, and then splice multiple track frames 3 through the connecting grooves 8 and connecting blocks 9. Insert the connecting blocks 9 accurately into the connecting grooves 8, and use bolts or pins and other connectors to pass through the connecting holes 10 to fix them, ensuring that multiple track frames 3 are connected into a stable overall frame. Push the display screen 1 so that the moving block 4 moves the display screen 1 within the track frame 3 (at this time, make sure that the display screen 1 is rotated so that it is not blocked by other display screens 1). Rotate the display screen 1 and insert the insert plate 16 into the constraint groove 15 to determine the angle of the display screen 1 so that all the display screens 1 are aligned. Then push the display screen 1 to bring all the display screens 1 closer together. At this time, all the display screens 1 will be spliced ​​together into a large display screen. Figure 1 (as shown); then rotate the rotating handle on the fixing bolt rod 13 to move the fixing bolt rod 13 inside the threaded tube 12, thereby driving the fixing plate 14 to be tightly connected to the outer end of the track frame 3, thus fixing the position of the moving block 4 inside the track frame 3, thereby fixing the position of the display screen 1 in the track frame 3. The display screen 1 is connected to the control terminal via a data cable. The control terminal transmits the information to be displayed to the display screen 1 via the data cable. The display screen 1 receives and displays the relevant information. After use, first loosen the fixing bolt rod 13 to separate the fixing plate 14 from the outer end of the track frame 3, releasing the fixation of the moving block 4. Then, pull out the insert plate 16, rotate the display screen 1 to make it parallel to the other display screens 1, and then push the display screen 1 to make the moving block 4 move the display screen 1 within the track frame 3, stacking multiple display screens 1 together, and making the rear back plates of the two outermost display screens 1 face outwards. Figure 2 (As shown), finally, a dust cover can be used to cover all the stacked displays 1 for protection, facilitating storage and transportation.
