An adjustable height display column

Abstract

This utility model relates to the field of display panel technology, specifically an adjustable-height display panel, including a display frame. An electric telescopic rod is fixedly connected to the bottom of the display frame, and a solar panel is installed on the top of the display frame. A poster mounting mechanism is installed inside the display frame. The advantages are as follows: by cooperating with the display frame and the poster mounting mechanism, the top of the poster is clamped and fixed by several fixing clips. Rotating the handle drives the threaded rod to rotate, causing the threaded rod and the movable block to perform threaded movement, which in turn drives rotating rod one and rotating rod two to rotate. This changes the height of the scissor-type adjusting component one and the connecting component, allowing the movable rod to slide along the inner wall of the display frame to the top, thus unfolding and fixing the poster inside the display frame. This makes poster replacement smoother, reduces installation time and labor costs, and effectively increases safety during the replacement process.

Description

Technical Field

[0001] This utility model relates to the field of display panels, specifically an adjustable-height display panel. Background Technology

[0002] A display panel is a device used to showcase information, works, or products. It is widely used in various fields such as commercial advertising, museum exhibitions, education and training, and corporate promotion. By optimizing the background design of display panels, not only is the visual effect of the displayed content enhanced, but the interactive experience of the audience is also strengthened, thereby effectively conveying information and improving brand image. Against this backdrop, the research and application of display panel background technology is particularly important, bringing new technological innovations to the display industry.

[0003] Existing display stands typically feature a fixed height design, making it impossible to adjust the height according to usage scenarios and user needs. To address this issue, some display stands have begun to adopt height-adjustable designs. These designs utilize built-in adjustment mechanisms, such as lifting rods, sliders, racks and pinions, manual adjustment screws, hydraulic rods, or electric lifting systems, to accommodate the viewing needs of people of different heights and facilitate content replacement and maintenance.

[0004] However, existing display technology still has some problems. First, some adjustment mechanisms are complex to operate, requiring professional personnel and are not convenient for the general public. Second, with the rapid pace of information updates, display boards need to frequently change posters. In existing technologies, display boards usually use an openable frame structure, and workers fix the posters inside the top of the frame. This generally requires the use of ladders or other climbing tools to reach the height for installation, which increases installation time and labor costs, as well as the danger of installing posters. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see the appendix Figure 1-4 This application provides the following technical solutions.

[0023] An adjustable-height display panel includes a display frame 1, an electric telescopic rod 2 fixedly connected to the bottom of the display frame 1, a solar panel 3 installed on the top of the display frame 1, and a poster mounting mechanism 4 installed inside the display frame 1. The display frame 1 includes a display frame body 11, a rotating handle 15 rotatably connected to one side of the display frame body 11, a threaded rod 14 fixedly connected to one side of the rotating handle 15, a limiting groove 13 formed at the bottom of the display frame body 11, the inner walls of the limiting groove 13 rotatably connected to the threaded rod 14 at both ends, the poster mounting mechanism 4 includes two movable blocks 41, the middle of the two movable blocks 41 threadedly connected to the threaded rod 14, the outer walls of the two movable blocks 41 slidably connected to the limiting groove 13, and a scissor-type adjustment component 42 rotatably connected to the top of the two movable blocks 41. The scissor-type adjustment component 42 includes a rotating rod 421, a rotating groove 422 extending through the middle of the rotating rod 421, and a rotating mechanism 422 rotatably connected to the middle of the rotating groove 422. The width of the second rotating rod 423 is equal to the width of the rotating groove 422. The bottom ends of the first rotating rod 421 and the second rotating rod 423 are rotatably connected to the movable block 41 via rotating shafts. The top ends of the first rotating rod 421 and the second rotating rod 423 are rotatably connected to the connecting parts 43 via rotating shafts. The top of the two connecting parts 43 is rotatably connected to the second scissor-type adjusting part 44. The second scissor-type adjusting part 44 has the same structure as the first scissor-type adjusting part 42. The top ends of the second scissor-type adjusting part 44 are rotatably connected to the rollers 45 via rotating shafts. The inner wall of the display frame body 11 is slidably connected to the movable rod 46. The bottom of the movable rod 46 is provided with a sliding groove 47. The side of the movable rod 46 is provided with a guide rail 48. The sliding groove 47 is connected to the guide rail 48. The inner wall of the guide rail 48 is movably connected to the rollers 45. The top of the movable rod 46 is fixedly connected to several fixing clips 49. The top two ends of the movable rod 46 are fixedly connected to the inserts 410.

[0024] It should be noted that when replacing the poster, the operator rotates the handle 15 to drive the threaded rod 14 to rotate. The threaded rod 14 and the movable block 41 make threaded movements, causing the two movable blocks 41 to slide towards each other along the inner wall of the limiting groove 13. This causes the rotating rod 1 421 to rotate, making the rotating rod 2 423 rotate in the rotating groove 422. This causes the two connecting parts 43 to move towards each other, causing the scissor-type adjusting part 2 44 to produce the same movement as the scissor-type adjusting part 1 42. The scissor-type adjusting part 2 44 slides on the inner wall of the sliding groove 47, causing the two rollers 45 to roll towards each other on the inner wall of the guide rail 48. At this time, the movable rod 46 moves downward, causing the insert 410 to disengage from the inner wall of the slot 17 until the movable rod 46 reaches the bottom. The operator then opens the transparent rotating frame 16 by rotating the hinge, releases the fixing clip 49, and removes the poster for replacement.

[0025] A slot 12 is provided on one side of the display frame body 11. A transparent rotating frame 16 is rotatably connected to the top of the display frame body 11 via a hinge. Two slots 17 are provided on the top of the inner wall of the transparent rotating frame 16. When the movable rod 46 reaches the top of the inner wall of the display frame body 11, the insert 410 is inserted into the inner wall of the slot 17. Limiting plates 18 are fixedly connected to the bottom of both sides of the inner wall of the display frame body 11 and the transparent rotating frame 16. When the insert 410 is inserted into the inner wall of the slot 17, the transparent rotating frame 16 is inserted into the slot 12, and the limiting plates 18 on the display frame body 11 and the limiting plates 18 on the transparent rotating frame 16 are in contact.

[0026] It should be noted that after the new display poster is fixed by several fixing clips 49, the staff will rotate the transparent rotating frame 16 into the slot 12 by using the top hinge of the display frame body 11. The reverse rotation of the rotating handle 15 will drive the threaded rod 14 to rotate, so that the threaded rod 14 and the movable block 41 make threaded movements, causing the two movable blocks 41 to move in opposite directions. At this time, the movable rod 46 moves upward along the inner wall of the display frame body 11 until the transparent rotating frame 16 reaches the top. At this time, the insert block 410 is inserted into the inner wall of the slot 17 to restrict the rotation of the transparent rotating frame 16. The limiting plate 18 on the transparent rotating frame 16 and the limiting plate 18 on the display frame body 11 are attached to each other to fix the bottom corner of the poster.

[0027] When replacing the poster, the operator rotates the handle 15, causing the threaded rod 14 to rotate. The threaded rod 14 moves threadedly with the movable block 41, causing the two movable blocks 41 to slide towards each other along the inner wall of the limiting groove 13. This causes the rotating rod 421 to rotate, making the rotating rod 423 rotate within the rotating groove 422. This causes the two connecting parts 43 to move towards each other, causing the scissor-type adjusting part 44 to move in the same direction as the scissor-type adjusting part 42. The scissor-type adjusting part 44 slides along the inner wall of the sliding groove 47, causing the two rollers 45 to roll towards each other along the inner wall of the guide rail 48. At this time, the movable rod 46 moves downwards, causing the insert 410 to disengage from the inner wall of the slot 17 until the movable rod 46 reaches the bottom. The operator then opens the transparent rotating frame 16 by rotating the hinge, loosens the fixing clips 49, and removes the poster for replacement. Once the new poster is secured by several fixing clips 49... The staff rotates the transparent rotating frame 16 into the slot 12 by using the top hinge of the display frame body 11. The reverse rotation of the rotating handle 15 drives the threaded rod 14 to rotate, causing the threaded rod 14 and the movable block 41 to make threaded movements, so that the two movable blocks 41 move in opposite directions. At this time, the movable rod 46 moves upward along the inner wall of the display frame body 11 until the transparent rotating frame 16 reaches the top. At this time, the insert block 410 is inserted into the inner wall of the slot 17 to restrict the rotation of the transparent rotating frame 16. The limiting plate 18 on the transparent rotating frame 16 and the limiting plate 18 on the display frame body 11 are attached to each other to fix the bottom corner of the poster. When in use, the operator can easily adjust the height of the display column through the electric telescopic rod 2 to meet the needs of people of different heights. At the same time, solar energy is collected through the solar panel 3 at the top of the display frame 1 to power the electric telescopic rod 2.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
