Technical Field
[0001] This utility model belongs to the field of projection technology, specifically relating to a holographic image projector. Background Technology
[0002] Holographic projection technology, also known as virtual imaging technology, is a technique that uses the principles of interference and diffraction to record and reproduce a true three-dimensional image of an object. Holographic projection technology can not only create three-dimensional aerial illusions, but also allow these illusions to interact with performers, creating a stunning performance effect. Applications include product exhibitions, car and fashion shows, stage performances, interactive experiences, bar entertainment, and interactive projection in various venues.
[0003] Existing holographic projectors have a relatively small range of angle adjustment, making it difficult to adjust the orientation of the holographic projector in multiple directions according to actual projection needs, resulting in significant limitations in the projection process. To address this, we propose a holographic image projector. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3This utility model provides a technical solution: a holographic image projector, including a base 1, a fixing hole 2 on one side of the base 1, a support 3 above the base 1, a limiting hole 4 on the surface of the support 3, a fixing block 5 above the support 3, a ball bearing 6 at the bottom of the fixing block 5, a connecting hole 7 at the top of the fixing block 5, a threaded rod 8 inside the connecting hole 7, a limiting piece 9 on the surface of the threaded rod 8, a knob 10 at the top of the threaded rod 8, a mounting plate 11 on the surface of the threaded rod 8, a support shaft 12 at the top of the mounting plate 11, a projector body 13 at the top of the support shaft 12, a worm gear 14 at the bottom of the mounting plate 11, fixing brackets 15 on both sides of the mounting plate 11, a connecting shaft 16 between the fixing brackets 15, and a worm gear 17 on the surface of the connecting shaft 16.
[0019] Specifically, three sets of supports 3 are fixedly installed on the top of the base 1. Limiting holes 4 are fixedly formed on the upper surface of each support 3. A ball shaft 6 is fixedly connected to the bottom of the fixing block 5. The ball shaft 6 is rotatably limited and connected to the inner side of the limiting hole 4. A threaded rod 8 is threadedly connected to the inner side of the connecting hole 7. A limiting piece 9 is provided on the surface of the threaded rod 8. A knob 10 is fixedly installed at the top of the threaded rod 8. A mounting plate 11 is sleeved between the limiting piece 9 and the knob 10 on the surface of the threaded rod 8. The limiting piece 9 is fixedly installed on the surface of the threaded rod 8. The mounting plate 11... A support shaft 12 is rotatably connected to the top center of the mounting plate 11. The top of the support shaft 12 is fixedly connected to the projector body 13. A worm gear 14 is rotatably connected to the bottom of the mounting plate 11. The top of the worm gear 14 is fixedly connected to the bottom end of the support shaft 12. Fixing frames 15 are fixedly connected to both sides of the mounting plate 11. A connecting shaft 16 is rotatably connected between the fixing frames 15. Both ends of the connecting shaft 16 extend to the outside of the fixing frames 15. A worm 17 is fixedly connected to the surface of the connecting shaft 16. One side of the worm 17 is connected to the worm gear 14 for transmission.
[0020] In this embodiment, the base 1 and the fixing hole 2 facilitate the fixation of the device's position. By rotating the knob 10, the threaded rod 8 can be rotated inside the connecting hole 7, allowing the threaded rod 8 to move vertically within the connecting hole 7.

Through the ball shaft 6 and the fixing block 5, when one side of the mounting plate 11 is lifted or lowered, the force generated on the other two sides will cause the ball shaft 6 to automatically rotate and adjust within the limiting hole 4, improving the stability of the mounting plate 11. By rotating both ends of the connecting shaft 16, the worm gear 17 and the worm wheel 14 can be rotated, thereby adjusting the horizontal angle of the projector body 13 at the upper end of the support shaft 12, improving the device's performance.
