Specific embodiments

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] As given by Figures 1 to 3 The present invention includes a bottom plate 1, a rectangular upper frame 2 and a glass 3. The glass 3 is installed in the middle of the rectangular upper frame 2. First folding baffles 4 are connected between both ends of the bottom plate 1 and the rectangular upper frame 2. A second folding baffle 5 is connected between one side of the bottom plate 1 and the rectangular upper frame 2. Two third folding baffles 6 are symmetrically connected between the other side of the bottom plate 1 and the rectangular upper frame 2. The bottom plate 1 and the rectangular upper frame 2 are connected by two telescopic mechanisms. Two folding support legs 7 are installed at the bottom of the bottom plate 1. A fixed rod 8 is connected between the middles of the two folding support legs 7.

[0016] Each of the first folding baffle 4, the second folding baffle 5 and the third folding baffle 6 is composed of four slats and five connecting shafts. Adjacent slats and the slats and the bottom plate 1 and the rectangular upper frame 2 are rotatably connected by connecting shafts, so that effective folding can be carried out, and effective adjustment can be made after the bottom plate 1 and the rectangular upper frame 2 are folded.

[0017] Each of the two folding support legs 7 includes a pair of first rotating upper legs 9. The two pairs of first rotating upper legs 9 are symmetrically and rotatably connected to the bottom of the bottom plate 1. A connecting rod 10 is rotatably connected between the lower parts of each pair of first rotating upper legs 9. Both sides of the connecting rod 10 are fixedly connected with lower legs 11. Rollers 12 are installed at the bottoms of the lower legs 11. Threaded holes 13 are symmetrically opened in the middles of the two connecting rods 10. Two threaded ends 14 are symmetrically opened at both ends of the fixed rod 8. The two threaded ends 14 are respectively threadedly connected with the two threaded holes 13, so that the folding support legs 7 can be effectively folded and adjusted;

[0018] By rotating the fixed rod 8, the threaded ends 14 at both ends of the fixed rod 8 are removed from the interiors of the two threaded holes 13, and then the fixed rod 8 is removed from between the two connecting rods 10. Subsequently, the first rotating upper leg 9, the rotating connecting rod 10, and the lower leg 11 can be rotated, causing the first rotating upper leg 9 and the connecting rod 10 to fold at the bottom of the bottom plate 1, thereby reducing the height of the display cabinet and facilitating transportation and storage.

[0019] Both telescopic mechanisms are connected and each includes two pairs of fixed blocks 15 and two inverted convex-shaped grooves 18. The two pairs of fixed blocks 15 are fixedly installed on both sides of the bottom of the rectangular upper frame 2, and the two inverted convex-shaped grooves 18 are opened on both sides of the top of the bottom plate 1. A first sliding rod 16 is fixedly installed between each pair of fixed blocks 15, and two first sliders 17 are slidably installed on the surfaces of the two first sliding rods 16. A second sliding rod 19 is fixedly installed on the upper part of each of the two inverted convex-shaped grooves 18, and two second sliders 20 are slidably installed on the surfaces of the two second sliding rods 19. An X-shaped movable frame 21 is rotatably connected between the four corners of the bottom plate 1 and the rectangular upper frame 2. The other ends of the upper and lower parts of the X-shaped movable frame 21 are respectively rotatably connected to the opposite first slider 17 and second slider 20, so that the four X-shaped movable frames 21 can effectively perform telescopic folding adjustment; Four inverted T-shaped fixing pins 22 are fixedly installed at the bottom of the bottom plate 1, and an adjusting plate 23 is movably installed between the four inverted T-shaped fixing pins 22. Springs 24 are installed on the surfaces of the four inverted T-shaped fixing pins 22, and the two ends of the springs 24 are respectively fixedly connected to the bottom plate 1 and the adjusting plate 23. The two ends of the bottom of each of the two inverted convex-shaped grooves 18 are movably inserted with a limit pin 25, and the four limit pins 25 all movably penetrate the bottom plate 1 and are fixedly connected to the top of the adjusting plate 23. A rotating rod 26 is rotatably connected to the middle of the bottom of the bottom plate 1, and an eccentric wheel 27 in contact with the top of the adjusting plate 23 is fixedly connected to the middle of the rotating rod 26. A rotating wheel is fixedly connected to one end of the rotating rod 26, so that the rectangular upper frame 2 can be effectively folded downwards;

[0020] When it is necessary to fold the rectangular upper frame 2 downwards, the rotating rod 26 is rotated through the rotating wheel. The rotation of the rotating rod 26 will drive the eccentric wheel 27 to rotate and squeeze the adjusting plate 23, causing the adjusting plate 23 to move downwards on the surfaces of the four inverted T-shaped fixing pins 22 and stretch the spring 24. The downward movement of the adjusting plate 23 will drive the four limit pins 25 to move downwards, causing the four limit pins 25 to be separated from and contact the lower parts of the four second sliders 20 respectively;

[0021] Then, the rectangular upper frame 2 is pressed downwards. The downward movement of the rectangular upper frame 2 will cause the first folding baffle 4, the second folding baffle 5, and the third folding baffle 6 to fold. At the same time, the four X-shaped movable frames 21 will be rotated and compressed, causing the first slider 17 and the second slider 20 to slide on the surfaces of the first sliding rod 16 and the second sliding rod 19 respectively. Finally, the rectangular upper frame 2 moves downwards to present a folded state with the bottom plate 1, reducing the space occupied during transportation and storage.

[0022] One end at the bottom of the second slider 20 is an extrusion inclined surface, and one end at the top of the limit pin 25 is a pressure-receiving inclined surface, so that the X-shaped movable frame 21 can stably support the rectangular upper frame 2 after being unfolded;

[0023] When it is necessary to unfold the pressing rectangular upper frame 2, by lifting the pressing rectangular upper frame 2, the pressing rectangular upper frame 2 drives the four X-shaped movable frames 21 to rotate and unfold, driving the first slider 17 and the second slider 20 to slide on the surfaces of the first slide bar 16 and the second slide bar 19 respectively. The movement of the second slider 20 presses down the limit pin 25 through the extrusion inclined surface and the pressure-receiving inclined surface. Finally, due to the elastic force of the spring 24, the four limit pins 25 will block on one side of the lower part of the four second sliders 20, so that the four unfolded X-shaped movable frames 21 can stably support the rectangular upper frame 2.

[0024] This lifting display cabinet has the functions of telescopic folding and height adjustment. It can reduce the occupation of space position and space waste during the transportation and storage of the display cabinet, thereby increasing the quantity of display cabinets transported and stored.

[0025] At the same time, the structure of this lifting display cabinet is simply designed, convenient and easy to operate, and stable and reliable in use and adjustment. Its performance can meet the use requirements.
