Description

Technical Field

[0001] This utility model relates to the field of exhibition and display technology, specifically a hand-cranked adjustable display structure. Background Technology

[0002] Currently, exhibit descriptions are often presented in text form through exhibition posters. However, for large-scale exhibits, this requires large posters or multiple posters to achieve a complete display. This makes content retrieval cumbersome, requiring physical adjustments and movement, which increases the risk of bumping into others or other items within the exhibit area, and also limits the amount of content displayed. Some exhibits use audio displays, but this method often lacks adjustable playback speed, preventing visitors from clearly and quickly understanding the exhibits. All of these presentation methods are relatively simplistic, hindering visitors' ability to independently and conveniently review and search the exhibits based on their existing knowledge, resulting in insufficient flexibility, engagement, interactivity, and content richness. Utility Model Content

[0003] The purpose of this utility model is to provide a hand-cranked adjustable display structure to address the problem that existing exhibits are presented in a relatively simple way, making it difficult for visitors to review and consult the exhibits independently and conveniently based on their own understanding of the content, resulting in insufficient flexibility, interest, interactivity, and content richness of the exhibits.

[0023] Beneficial effects:

[0024] This utility model relates to a hand-cranked adjustable display structure. Visitors, while viewing the exhibit, crank the handle to rotate the first rotating shaft, causing the first wheel to rotate synchronously. This, in turn, drives the second wheel and second rotating shaft via a transmission belt. Through the meshing of a gear ring, the second rotating shaft further rotates, thus rotating the rollers and causing the display poster to move, allowing for the switching of content exposed on the transparent glass panel. Simultaneously, a damping sleeve applies friction to the first rotating shaft, positioning the hand-cranked mechanism, rollers, and display poster. A sensor detects a flexible sensing block to determine the position of the display poster and the currently displayed content, linking it to a display screen to switch and display the screen image corresponding to the displayed content. This design allows visitors to autonomously switch and view the exhibit content. The combination of text-based display and video-based video presentation enhances the flexibility, interest, interactivity, and content richness of the exhibit. Attached Figure Description

[0034] Please see Figure 1-4 This utility model provides a technical solution: a hand-cranked adjustable display structure, comprising:

[0035] Cabinet 1 is installed in the mounting cavity of the display wall or display case. A door 2 is provided on the outside of the mounting cavity. Several windows 3 are hollowed out on the door 2. A transparent glass plate 4 and a display screen 5 are arranged in the windows 3. Several rollers 6 are provided at the top and bottom of the inner cavity of the cabinet 1.

[0036] The annular display 7 is tensioned and fitted on several rollers 6, which correspond to the transparent glass plate 4;

[0037] The hand-cranked mechanism includes a handle 8, a first rotating shaft 9, a first wheel 10, a damping seat 11, a transmission belt 12, and a linkage mechanism. The handle 8 is positioned at one end of the first rotating shaft 9. A guide seat 13 is provided on one side of the cabinet 1. The first rotating shaft 9 is rotatably mounted on a through hole in a guide frame 14 at the top of the guide seat 13. The first wheel 10 is positioned in the middle of the first rotating shaft 9. The transmission belt 12 is sleeved on the first wheel 10 and the linkage mechanism. The linkage mechanism is connected to at least one roller 6. The damping seat 11 is positioned on the side of the cabinet 1 and applies damping friction to the first rotating shaft 9.

[0038] A sealing plate 15 is provided on the outer side of the inner cavity of the cabinet 1, which can support the inner side of the door 2 and protect the internal components of the cabinet 1.

[0039] A limiting ring 16 is provided at the end of the roller 6. The limiting ring 16 abuts against the side of the display 7 to limit the display 7, prevent it from shifting laterally when it moves vertically or runs, and ensure that it is always vertical and the content displayed on it is clear.

[0040] The connecting post 17 at the inner end of the first rotating shaft 9 is rotatably inserted into the damping seat 11, and a damping sleeve is embedded between the damping seat 11 and the connecting post 17, thereby realizing automatic positioning after adjustment by the hand-crank mechanism and improving ease of use.

[0041] The linkage mechanism includes a second rotating shaft 18 and a third rotating shaft 19. The second rotating shaft 18 and the third rotating shaft 19 are rotatably connected to a first guide sleeve 20 on the side of the cabinet 1. A second wheel 21 is mounted on the second rotating shaft 18, and the transmission belt 12 is fitted onto the second wheel 21. A first gear ring 22 and a second gear ring 23 are respectively mounted on the second rotating shaft 18 and the third rotating shaft 19, which are meshed with each other. The third rotating shaft 19 passes through one side of the cabinet 1 and is connected to the end of the roller shaft 6 via a connecting shaft 24. The connecting shaft 24 is rotatably inserted into the second guide sleeves 25 on both sides of the inner cavity of the cabinet 1. This improves the efficiency of the structural transmission.

[0042] Sensors 26 are installed inside the cabinet 1, and several flexible sensing blocks 27 corresponding to several display content modules are installed on the side of the display 7. The sensors 26 are used to sense the position of the flexible sensing blocks 27. The sensors 26 are associated with the display screen 5. In use, by operating the hand crank mechanism, the display 7 moves together with the roller 6, and its front moves up or down to switch the displayed content. At the same time, the flexible sensing blocks 27 move with the display 7. The sensors 26 sense the flexible sensing blocks 27 at their positions to determine the position of the display 7, and then determine the content displayed through the transparent glass plate 4. The sensors 26 transmit wireless signals and are associated with the control module of the display screen 5 to realize the switching and presentation of the screen image of the display screen 5 corresponding to the content displayed on the display 7.

[0043] The working principle of a hand-cranked adjustable display structure in this embodiment includes: When a visitor learns about the exhibit, they crank the handle 8, causing the first rotating shaft 9 to drive the first wheel 10 to rotate synchronously. This, in turn, drives the second wheel 21 and the second rotating shaft 18 to rotate via the transmission belt 12. Through the meshing connection of the gear ring, the third rotating shaft 19 is further driven to rotate. This, in turn, drives the display poster 7 to rotate via the rotation of the roller 6, thereby switching the content displayed on the display poster 7 exposed in the transparent glass plate 4. At this time, the frictional force applied to the first rotating shaft 9 by the damping sleeve achieves the positioning of the hand-cranked mechanism, the roller 6, and the display poster 7. Simultaneously, the sensor 26 senses the flexible sensing block 27 to determine the position of the display poster 7 and the currently displayed content, and associates it with the display screen 5 to switch and present the screen image on the display screen 5 corresponding to the content displayed on the display poster 7. This design allows visitors to independently switch and view the display content. The diverse presentation of the text in the display poster combined with the video display on the screen enhances the flexibility, interest, interactivity, and content richness of the exhibit.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
