Description

Technical Field

[0001] The utility model relates to a display device, in particular to a picture display device. Background Art

[0002] In numerous fields, including art exhibitions, cultural promotion, and commercial displays, image presentations are a crucial means of conveying information and showcasing the charm of art. Traditionally, image presentations have employed fixed hanging frames or posted panels, which present numerous limitations. Once a hanging frame is positioned, its height and angle are difficult to adjust, making it difficult to accommodate the viewing needs of viewers of varying heights or diverse display scenarios. Posting images on panels is not only cumbersome and difficult to change, but also presents a monotonous display format that struggles to capture audience attention.

[0003] Furthermore, existing display devices still lack functional integration and flexibility. While some devices have lifting functions, they lack multi-angle rotation and flipping capabilities, making them incapable of all-round display. Furthermore, they lack specialized components for displaying longer pictures, resulting in poor display effects. Furthermore, existing display devices generally lack storage functions, making it difficult to properly store auxiliary tools and spare pictures during the display process, hindering the orderly development of exhibition activities. Therefore, there is an urgent need for a picture display device with more complete functions and greater ease of use to meet increasingly diverse display needs. Utility Model Content

[0038] The auxiliary display board 8 is rotatably connected to both sides of the main display board 7 through a rotating shaft hinge. The front surfaces of the auxiliary display board 8 and the main display board 7 are respectively provided with a magnetic whiteboard layer, and the rear surfaces of the auxiliary display board 8 and the main display board 7 are respectively provided with a magnetic strip 11 that can be magnetically attracted to each other. When the auxiliary display board 8 is folded toward the rear of the main display board 7, the auxiliary display board 8 and the main display board 7 are connected to each other through the magnetic strip 11.

[0039] When in use, first unlock the lockable running wheels 2 to push the entire picture display device to the target display position. After arriving at the designated location, lock the lockable running wheels 2 to firmly fix the device and prevent it from moving during use. Then, adjust the height of the display device through the electric lifting rod 3. Start the electric lifting rod 3 to perform telescopic movement and adjust the lower support frame 5 together with the upper display board to a height suitable for the audience to watch.

[0040] When the display angle needs to be adjusted, (1) horizontal rotation: start the motor 1 404 in the first rotating assembly 4, the motor 1 404 drives the second gear plate 403 to rotate, and since the second gear plate 403 is engaged with the first gear plate 402, the rotating platform 401 is horizontally rotated on the top of the electric lifting rod 3, so that the horizontal angle adjustment of the lower support frame 5 and the display board is achieved, which is convenient for displaying pictures from different directions; (2) tilt rotation: turn on the motor 2 604 in the second rotating assembly 6, the motor 2 604 drives the fourth gear plate 603 to rotate, and the fourth gear plate 603 drives the third gear plate 602 engaged with it to rotate, so that the main display board 7 is flipped in the vertical direction through the rotating shaft 601, and the tilt angle of the main display board 7 can be adjusted according to the display requirements.

[0041] When the display area needs to be increased, the secondary display panels 8 can be unfolded and extended outward from both sides of the main display panel 7 via the hinges. The locking pins 901 at the bottom of the secondary display panels 8 are pushed to engage with the locking holes at the bottom of the main display panel 7, securing the secondary display panels 8. At this point, the magnetic whiteboard layers on the front surfaces of the secondary display panels 8 and the main display panel 7 can be used for writing or pasting display content. When the secondary display panels 8 are folded and stowed, the magnetic strips 11 on the back surfaces of the secondary display panels 8 and the main display panel 7 connect magnetically to each other, allowing the secondary display panels 8 to be stored.

[0042] When it is necessary to use a scroll to assist in display, pull the handle 1009 at the bottom of the lower clamping plate 1002, so that the lower clamping plate 1002 overcomes the elastic force of the return spring 1008 and moves downward along the guide rod 1007 in the vertical groove 1006, thereby separating from the upper clamping plate 1001; place the upper and lower ends of the picture between the upper clamping plate 1001 and the lower clamping plate 1002 respectively, release the handle 1009, and under the action of the return spring 1008, the lower clamping plate 1002 moves upward and fits tightly against the upper clamping plate 1001 to clamp the picture. When the picture is too long, the end rotating plate 1003 can be rotated to rotate the upper clamping plate 1001 and the lower clamping plate 1002 to partially reel it up.

[0043] When it is necessary to store relevant display materials or tools, the bottom storage box 104 is rotated and taken out from between the upper base plate 101 and the lower base plate 102 of the base 1, and the items are placed in the bottom storage box 104. After use, the bottom storage box 104 is rotated back to its original position.

It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0045] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
