[0039] Example 3:

[0040] Reference Figure 7 and Figure 8The connecting column 2 has a disassembly assembly 8 inside, and a slider 9 is fixedly connected to the outside of the disassembly assembly 8. The connecting column 2 has a sliding groove 10 inside, and the slider 9 is slidably connected to the inside of the sliding groove 10. The disassembly assembly 8 includes a second spring 801, which is located inside the connecting column 2. A circular plate 802 is located at one end of the second spring 801. A drive rod 803 is fixedly connected to the top of the circular plate 802. A locking block 804 is fixedly connected to the outside of the circular plate 802. A locking groove 805 is located inside the display panel body 5. The circular plate 802 is fixedly connected to the outside of the slider 9. The circular plate 802, drive rod 803, and locking block 804 are all slidably connected to the inside of the connecting column 2. The locking block 804 is locked into the inside of the locking groove 805.

[0041] Specifically, in this embodiment, the disassembly assembly 8 is used to realize the detachable connection between the display panel body 5 and the connecting column 2. The slider 9 is fixed outside the disassembly assembly 8 and slidably connected in the slide groove 10 of the connecting column 2. It can slide along the slide groove 10 to prevent the disassembly assembly 8 from shifting when it moves. The second spring 801 is located inside the connecting column 2 and can drive the circular plate 802 to reset through elastic deformation. The circular plate 802 is used to slide along the connecting column 2 under the drive of the drive rod 803. The drive rod 803 is used for user operation. When pushed, it drives the circular plate 802 and the locking block 804 to move. The locking block 804 can slide with the circular plate 802 and lock into or disengage from the locking groove 805 of the display panel body 5, thereby realizing the installation, fixing or disassembly and replacement of the display panel body 5, so as to facilitate the individual maintenance or replacement of the display panel body 5.

[0042] Working principle: When the display board body 5 needs to be folded and stored, firstly, pull the limiting rod 4 out from the bottom plate 1 and the limiting groove 3, then rotate the connecting column 2 to make the display board body 5 fit against the bottom plate 1, then push the support plate 602 to slide along the support base 601 so that the locking column 604 is locked into the locking groove 605, then rotate the rotating rod 603 to lock it on the outside of the support plate 602. Alternatively, by pressing the pressing block 609, the transmission plate 608 can be moved and the first spring 607 can be compressed. After folding the display board body 5, release the pressing block 609 so that the first spring 607 is reset and pushes the transmission plate 608 to move, thereby making the buckle 610 lock on the top of the connecting plate 611, thus completing the folding. This achieves the folding and storage of the display board body 5, reducing the overall volume. With the handle 7, it can be easily carried, saving transportation and storage space and adapting to mobile demonstration scenarios.

[0043] When it is necessary to disassemble or replace the display panel body 5, firstly, by pushing the drive rod 803, the circular plate 802 is slid and the second spring 801 is compressed, thereby causing the circular plate 802 to drive the locking block 804 to disengage from the locking groove 805. At the same time, the circular plate 802 drives the slider 9 to slide along the slide groove 10. At this time, the display panel body 5 can be removed. When installing the new display panel body 5, the drive rod 803 is released, thereby causing the second spring 801 to reset and push the circular plate 802 to slide, thereby causing the locking block 804 to engage with the locking groove 805, completing the installation and fixing of the display panel body 5. This facilitates individual maintenance or replacement, thereby reducing maintenance costs.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
