Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a display device for park management. Background Technology

[0002] As a carrier of information visualization and interaction, display devices have been developed across multiple fields, including commercial exhibitions, public services, and education and popular science. From early static display boards and stands to today's dynamic devices that integrate mechanical transmission, intelligent control, and multimedia technologies, the core function of display devices has always revolved around efficiently conveying information and enhancing user experience. In park management scenarios, the application scenarios of display devices have gradually expanded from simple information display to a composite functional field of guidance, data monitoring visualization, and security linkage.

[0003] Park management display devices are integrated systems based on the management needs of the park environment. They consist of hardware carriers such as displays, mechanical supports, interactive terminals, software systems, and mechanical structures. These systems include display modules, support and drive modules, and control modules. However, traditional park management display devices have significant drawbacks. Their structural fixation and scene adaptability are insufficient. Most devices are fixedly installed, making it difficult to dynamically adjust the display angle, height, and position according to park traffic and activity needs, resulting in limited information coverage. To address these drawbacks, existing technologies use gear and rack / pinion and worm gear transmission mechanisms to raise and lower the display screen. Manual knobs and motor-driven support joints allow the device to adapt to different height requirements. However, existing technologies suffer from a contradiction between mechanical transmission precision and stability. Gear transmission is easily affected by load changes, and long-term gear wear can lead to decreased angle adjustment precision, resulting in problems such as screen tilting and stuttering, thus reducing practicality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a display device for park management, which aims to improve the problems of gear transmission being easily affected by load changes, and gear wear after long-term use leading to decreased angle adjustment accuracy, display screen tilting and stuttering, resulting in low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a display device for park management, comprising an installation plate, a support frame fixedly connected to the top of the installation plate, a hollow plate fixedly connected to the top of the support frame, an extension mechanism provided on the hollow plate, a lifting mechanism provided at the bottom of the installation plate, the lifting mechanism being used for lifting, and a base plate provided at the bottom of the lifting mechanism.

[0006] The extension mechanism includes an extension plate, a sliding plate slidably connected to the left outer wall of the extension plate, a sliding groove provided on the inner wall of the sliding plate, a sliding component provided at the bottom of the sliding groove, and an adjustment component provided at the top of the mounting plate.

[0007] As a further description of the above technical solution:

[0008] The lifting mechanism includes a slide rail 2, the outer wall of which is fixedly connected to the bottom inner wall of the mounting plate, and a slider 2 is slidably connected to the outer wall of the slide rail 2, with a rotating component at the bottom of the slider 2.

[0009] As a further description of the above technical solution:

[0010] The sliding assembly includes multiple reinforcing plates. The top of the left reinforcing plate is fixedly connected to the bottom of the sliding plate. A movable block is fixedly connected to the bottom of the reinforcing plate. A support component is provided on the inner wall of the movable block. A fixing component is provided on the right side of the right reinforcing plate.

[0011] As a further description of the above technical solution:

[0012] The fixing component includes a U-shaped plate, the left side of which is fixedly connected to the right side of the reinforcing plate, and a rotating plate is rotatably connected to the inner wall of the U-shaped plate.

[0013] As a further description of the above technical solution:

[0014] The support assembly includes a guide roller, the outer wall of which is slidably connected to the inner wall of the movable block, and support plates are fixedly connected to both the left and right sides of the guide roller. The bottom of the support plate is fixedly connected to the top of the mounting plate.

[0015] As a further description of the above technical solution:

[0016] The adjustment assembly includes a slide rail, the outer wall of which is fixedly connected to the top inner wall of the mounting plate, and a slider is slidably connected to the outer wall of the slide rail. The top of the slider is slidably connected to the support frame on the left side.

[0017] As a further description of the above technical solution:

[0018] The rotating assembly includes an X-shaped plate, the top of which is fixedly connected to the bottom of the second slider, a rotating column is rotatably connected to the middle of the X-shaped plate, and a pushing assembly is provided on the front inner wall of the X-shaped plate.

[0019] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by rotating the rotating plate, the reinforcing plates on both sides are released from their restraints. Then, the moving block on the right side moves along the guide roller, while the reinforcing plate on the right side moves synchronously. When the extended plate is moved to the appropriate position, the sliding plate is moved in the same way. Then, the rotating plate is rotated to fix the reinforcing plates on both sides. Then, the support frame on the left side is moved to the lower side of the sliding plate through the slide rail and the slider. This achieves the function of extending and shortening the display board, which enhances efficiency and provides stable support, thus enhancing practicality.

[0023] 2. In this utility model, by pushing the push rod backward by hand, the X-shaped plate rotates around the rotating column, making the included angle on both sides of the X-shaped plate smaller. At the same time, the sliders and sliding blocks on both sides move towards each other, lifting the mounting plate upward. Similarly, by pulling the push rod forward, the mounting plate moves downward, thus achieving the function of adjusting the height of the display board and enhancing its practicality.

Then, the moving block 2042 on the right side moves along the guide roller 2062. At the same time, the reinforcing plate 2041 on the right side moves synchronously. When the extension plate 201 is moved to the appropriate position, the sliding plate 202 is moved in the same way. Then, the rotating plate 2052 is rotated to fix the reinforcing plates 2041 on both sides. Then, the support frame 4 on the left side is moved to the lower side of the sliding plate 202 through the slide rail 2071 and the slider 2072. This achieves the function of extending and shortening the display board, which enhances efficiency and provides stable support, thus enhancing practicality.

[0042] By pushing the push rod 3041 backward by hand, the X-shaped plate 3031 rotates around the rotating column 3032, making the included angle between the two sides of the X-shaped plate 3031 smaller. At the same time, the sliders 301 and 3042 on both sides move closer to each other, lifting the mounting plate 1 upward. Similarly, pulling the push rod 3041 forward makes the mounting plate 1 move downward, thus achieving the function of adjusting the height of the display board and enhancing its practicality.
