[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0022] Refer to Figures 1-4, a liquid crystal display flipping stand, including a support frame 1, a flipping plate 2 is installed above the support frame 1, and a display body 3 is connected to the front of the flipping plate 2. The connection method and flipping principle between the support frame 1 and the flipping plate 2 are very mature technologies in the prior art, and will not be elaborated here. By flipping the flipping plate 2, the angle of the display body 3 can be adjusted. A connecting plate 4 is connected to the upper side of the flipping plate 2, and linkage rods 5 are symmetrically inserted inside the connecting plate 4. The outer sides of the linkage rods 5 are all connected to a protective plate 7 through linkage blocks 6. The tops of the linkage rods 5 are respectively connected to rotating blocks 8, and limit blocks 9 are inserted inside the rotating blocks 8. Card slots adapted to the limit blocks 9 are opened inside the connecting plate 4. Through the mutual cooperation of the card slots and the limit blocks 9, the limiting operation of the linkage rods 5 and the rotating blocks 8 can be realized, so that the protective plate 7 can be kept covering the display body 3 or rotated 180 degrees to the side of the display body 3.
[0023] Further, referring to Figure 4 It can be known that sleeve rods 14 are symmetrically connected to the upper and lower ends of the linkage rod 5, and the sleeve rods 14 are all connected to the linkage rod 5 through limit rods 15 inside. During use, through the mutual cooperation of the sleeve rods 14 and the limit rods 15, the connection between the linkage rod 5 and the linkage block 6 can be conveniently realized. Since the linkage block 6 is connected to the protective plate 7, it is convenient for the staff to timely disassemble and replace the protective plate 7 that has reached the service life.
[0024] Further, referring to Figure 4 It can be known that a guiding ring 12 is connected to the outer side of the linkage rod 5, and an annular groove adapted to the guiding ring 12 is opened inside the connecting plate 4. Through the setting of the guiding ring 12 and the annular groove, the stability of the linkage rod 5 during the rotation process can be effectively guaranteed.
[0025] Further, referring to Figure 4 It can be known that a limit groove adapted to the limit rod 15 is opened inside the linkage rod 5, and internal threads are opened on the inner wall of the limit groove. External threads are opened on the outer surface of the limit rod 15. The external threads and the internal threads are not shown in the figure. Through the mutual cooperation of the two, the tightness of the linkage block 6 sleeved on the outer side of the linkage rod 5 can be effectively guaranteed.
[0026] Further, referring to Figure 4 It can be known that the limit block 9 is set in a U-shaped structure, and the outer surface of the limit block 9 is closely attached to the inner wall of the card slot. Through the U-shaped limit block 9, the limiting effect on the rotating block 8 can be effectively improved.
[0027] Further, referring to Figure 4It can be known that connecting plates 10 are symmetrically sleeved on the lower side of the limit block 9, and the upper sides of the connecting plates 10 are all connected to the rotating block 8 through connecting springs 11. Through the mutual cooperation of the connecting plates 10 and the connecting springs 11, the tightness of the limit block 9 clamped inside the card slot of the connecting plate 4 can be further ensured.
[0028] Further, referring to Figure 3 and Figure 4 It can be known that writing boards 13 are respectively distributed on the back surface of the protection plate 7, and the sides of the writing boards 13 are connected to the protection plate 7 through magnets. There are two groups of magnets in total, and multiple magnets are provided in each of the two groups. Additionally, one group of magnets is connected to the protection plate 7, while the other group of magnets is connected to the writing board 13. Since the magnetic properties of the two groups of magnets are opposite, when the writing board 13 and the protection plate 7 approach each other, they will be attracted to each other due to the magnets, thereby realizing the installation of the writing board 13. Through the setting of the writing board 13, it is convenient for the staff to write important content during the meeting, so as to facilitate the participants' memory and understanding. And through the connection of the magnets, the writing board 13 can be removed for wiping after the meeting.
[0029] Working principle: When the present utility model is in use, the staff can first place the device at a suitable position in the meeting room. During the placement of the device, through the setting of the two protection plates 7, the display screen body 3 can be covered, thereby preventing dust from adhering. When a meeting needs to be held, the staff can first pull up the limit block 9, so that its bottom end is withdrawn from the card slot inside the connecting plate 4. Then the staff can rotate the rotating block 8 to drive the rotation of the linkage rod 5 and the linkage block 6, so that the protection plate 7 no longer covers the display screen body 3. When the protection plate 7 is rotated 180 degrees, the staff can stop pulling up the limit block 9, so that the position of the writing board 13 is restricted. Then the staff can adjust the flip board 2 to a suitable angle and height through the support frame 1, and then turn on the display screen body 3 to hold a meeting. After the meeting, the staff can pull up the limit block 9 again, and then rotate the rotating block 8, so that the two protection plates 7 cover the display screen body 3 again. The above is the entire working principle of the present utility model.
[0030] In the present utility model, the installation methods, connection methods or setting methods of all the above-mentioned components are common mechanical methods, and the specific structures, models and coefficient indexes of all its components are its own technologies. As long as they can achieve their beneficial effects, they can be implemented, so no more details will be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present utility model shall be equivalent replacement methods and are all included in the protection scope of the present utility model.
