[0024] In the specific implementation process, Figure 1-Figure 4 As shown, it includes a cabinet 1, and four projection display mechanisms are arranged on the top of the cabinet 1 in a square shape. The projection display mechanism includes a display glass 2, a top platform 3 and a bottom platform 4. An adjustment mechanism is arranged between the bottom platform 4 and the cabinet 1. The bottom of the top platform 3 is square and fixed with four load-bearing rods 5. The bottom of the load-bearing rods 5 is fixed on the bottom platform 4. The display glass 2 is installed on the bottom platform 4. A projection device 6 is arranged on the top of the display glass 2, and the projection device 6 is installed on the top platform 3. A pyramid-shaped display glass 2 is installed below the projection device 6. Through physical light refraction onto the display glass 2 with an imaging film attached, a three-dimensional virtual image is presented on the transparent display glass 2 using the principles of interference and diffraction, so that the audience can observe the suspended three-dimensional image from any position around the display glass 2. The display clarity is high, so it has a strong visual impact.

[0025] The adjustment mechanism includes a support shaft 8, a gear 9, a moving rod 10 and a rack 11. Four support shafts 8 are arranged in a square shape above the cabinet 1, and the four support shafts 8 are respectively located directly below the four bases 4. The bottom of the support shaft 8 is movably connected to the cabinet 1 through a bearing, and the top of the support shaft 8 is fixedly connected to the base 4. Two support seats 12 are fixed on the cabinet 1 at intervals, and a slide groove 13 is provided on the surface of the support seat 12. A slide rod 14 is slidably arranged inside the slide groove 13. A moving rod 10 is fixed above the slide rod 14. Two racks 11 are respectively fixed at both ends of the moving rod 10, and a gear 9 is arranged on one side of the rack 11. The gear 9 is installed on the support shaft 8, and the rack 11 is meshed with the gear 9. The two moving rods 10 are connected by a plurality of connecting rods 15. A motor 7 is installed on the cabinet 1, and a threaded rod 16 is installed on the output end of the motor 7. The threaded rod 16 penetrates the connecting rod 15, and the threaded rod 16 is threadedly connected to the connecting rod 15. In order to enable the viewer to view the items displayed inside the display glass 2 in all directions without moving, the staff can start the motor 7 to drive the threaded rod 16 to rotate. When the threaded rod 16 rotates, it will drive the connecting rod 15 and the two moving rods 10 to slide along the slide groove 13, and the moving rod 10 will drive the rack 11 to move when it moves, and the rack 11 will drive the gear 9 to rotate when it moves, so that the top platform 3, the bottom platform 4 and the display glass 2 rotate along with the support shaft 8, so that the viewer can complete the observation of the entire exhibit at the same position.

[0026] A truss 18 is fixed on the surface of the cabinet 1, and the truss 18 is located at the center of the four groups of projection display mechanisms. A distribution socket 19 is installed on the top of the truss 18. The distribution socket 19 is electrically connected to the projection device 6 through an extension wire 20. The extension wire 20 can ensure that the projection device 6 will not have the problem of wire entanglement when moving.

[0027] Filling lights 21 are installed around the distribution socket 19. By controlling the intensity of the light, the perfect sense of combining the real object with the video can be enhanced. A plurality of storage cabinets 17 are arranged on the cabinet body 1 for storing some sundries.

[0028] Working principle of the utility model: the projection display mechanism can increase the number of items displayed at the same time by setting four projection display mechanisms. In order to enable viewers to view the items displayed inside the display glass 2 in all directions without moving, the staff can start the motor 7 to drive the threaded rod 16 to rotate. When the threaded rod 16 rotates, it will drive the connecting rod 15 and the two moving rods 10 to slide along the slide groove 13. When the moving rod 10 moves, it will drive the rack 11 to move. When the rack 11 moves, it will drive the gear 9 to rotate, thereby making the top platform 3, the bottom platform 4 and the display glass 2 rotate along with the support shaft 8, so that the viewer can complete the observation of the entire exhibit at the same position.
