DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] Please refer to Figures 1-5As shown in the figure, a flipping rack for information display in a convention and exhibition center includes a display rack main body 1; a display board 2 is provided at the top of the display rack main body 1, and a fixing mechanism is provided between the display rack main body 1 and the display board 2;

[0025] The fixing mechanism includes a first fixing block 10. The first fixing block 10 is arranged on one side inside the top of the display rack main body 1. The rear end of the first fixing block 10 is welded to the rear end inside the display rack main body 1. The inside of the first fixing block 10 sleeves the outside of a rotating block 11, and the first fixing block 10 is rotatably connected to the rotating block 11. The inner wall of the first fixing block 10 and the rotating block 11 are both circularly designed. The front end of the rotating block 11 is welded to the rear end of a threaded rod 12. The front end of the threaded rod 12 passes through the front end inside the display rack main body 1 to the outside of the display rack main body 1, and the threaded rod 12 is rotatably connected to the first fixing block 10, and the front end of the threaded rod 12 is welded to the rear end of a rotating disc 13;

[0026] During operation, first lift the display board 2 to a position near the middle at the top of the display rack main body 1, and then rotate the rotating disc 13 on one side of the display rack main body 1 to drive the threaded rod 12 to rotate. The threaded rod 12 drives the rotating block 11 to rotate along the inside of the first fixing block 10 for fixing and then flipping the display board.

[0027] Furthermore, both ends of the outside of the threaded rod 12 are sleeved with moving blocks 14, and the threaded rod 12 is threadedly connected to the moving blocks 14. The moving blocks 14 are square in design. The top end of the moving block 14 is welded to the bottom end of a support rod 15. The thread grooves at both ends of the outside of the threaded rod 12 are designed in opposite directions. A rotating groove 16 is opened on one side of the support rod 15. The rotating groove 16 sleeves the outside of the rear end of a rotating rod 17, and the rotating groove 16 is rotatably connected to the rotating rod 17. The rotating groove 16 and the rear end of the rotating rod 17 are both circularly designed. The front end of the rotating rod 17 is adhesively bonded to the rear end of an anti-slip block 18. The front end of the anti-slip block 18 is attached to the side end of the display board 2;

[0028] During operation, the threaded rod 12 rotates, driving the moving blocks 14 on both sides of the surface of the threaded rod 12 to move towards the middle along the surface of the threaded rod 12, and simultaneously driving the support rod 15 to move synchronously until the rotating rod 17 at the side end of the support rod 15 clamps the side end of the display board 2. The anti-slip block 18 at the front end of the rotating rod 17 can play an anti-slip role. When the display board 2 is flipped, it drives the rotating rods 17 on both sides to rotate along the inside of the rotating groove 16 for fixing and then flipping the display board.

[0029] Further, on the other side of the support rod 15 at one side of the top end of the display rack main body 1, there is a pull block 19. The front end of the pull block 19 is welded to the rear end of the fixed rod 20. The front end of the fixed rod 20 is welded to the rear end of the insertion block 21. The front end of the insertion block 21 passes through the other side of the support rod 15 and is inserted into the inner part of the rear end of the rotating rod 17. Both the insertion block 21 and the inner wall of the rear end of the rotating rod 17 are designed as squares.

[0030] During operation, pull the pull block 19 outwards, driving the fixed rod 20 and the insertion block 21 to move outwards until the front end of the insertion block 21 disengages from the inner part of the rear end of the rotating rod 17. This is used to fix the display board and then flip it.

[0031] Further, a return spring 23 is sleeved on the outer side of the fixed rod 20 near the rear end. The front end of the return spring 23 is welded to the other side of the support rod 15, and the rear end of the return spring 23 is welded to the front end of the pull block 19.

[0032] During operation, pull the pull block 19 to drive the return spring 23 to be stretched and extended, which is used to fix the display board and then flip it.

[0033] Further, the bottom end of the pull block 19 is welded to the top end of the sliding block 24. The bottom end of the sliding block 24 is inserted into the second fixed block 25, and the sliding block 24 is slidably connected to the second fixed block 25. The sliding block 24 is designed as a square, and one side of the second fixed block 25 is welded to the other side of the support rod 15.

[0034] During operation, pull the pull block 19, and the sliding block 24 at the bottom end of the pull block 19 moves along the inside of the second fixed block 25, which is used to fix the display board and then flip it.

[0035] Further, universal wheels 26 are provided at the front and rear ends on both sides of the bottom end of the display rack main body 1, and the bottom end of the display rack main body 1 is welded to the top end of the universal wheels 26.

[0036] During operation, push the display rack main body 1 to drive the universal wheels 26 at the bottom end of the display rack main body 1 to move until it reaches the appropriate position. This is used to move the display flipping rack.

[0037] Working principle: When it is necessary to fix the display board and then turn it over, first lift the display board 2 to a position near the middle at the top of the display rack main body 1, and then rotate the rotating disk 13 on one side of the display rack main body 1 to drive the threaded rod 12 to rotate. The threaded rod 12 drives the rotating block 11 to rotate along the inside of the first fixing block 10. At the same time, when the threaded rod 12 rotates, it drives the moving blocks 14 on both sides of the surface of the threaded rod 12 to move towards the middle along the surface of the threaded rod 12, and at the same time drives the support rod 15 to move synchronously until the rotating rod 17 at the side end of the support rod 15 clamps the side end of the display board 2. The anti-slip block 18 at the front end of the rotating rod 17 can play an anti-slip role. When turning it over later, first pull the pull block 19 outwards to drive the fixed rod 20 and the insertion block 21 to move outwards until the front end of the insertion block 21 breaks away from the inside of the rear end of the rotating rod 17. And when pulling the pull block 19, the return spring 23 is stretched and extended. At the same time, the sliding block 24 at the bottom end of the pull block 19 moves along the inside of the second fixing block 25. Then turn over the display board 2 to drive the rotating rods 17 on both sides to rotate along the inside of the rotating groove 16. When turning it back, then loosen the pull block 19 to drive the insertion block 21 to insert into the inside of the rear end of the rotating rod 17 again to fix the position of the display board 2, which is used to fix the display board and then turn it over.

[0038] When it is necessary to move the display and turnover rack, push the display rack main body 1 to drive the universal wheels 26 at the bottom end of the display rack main body 1 to move until it reaches the appropriate position, which is used to move the display and turnover rack.
