Description

A naked-eye 3D display machine Technical Field

[0001] This utility model relates to the field of display equipment technology, and in particular to a naked-eye 3D display machine. Background Technology

[0002] With the rapid development of technology, 3D display technology has been widely used in many fields such as advertising, cultural exhibitions, and education. As an emerging display device, naked-eye 3D display machines have attracted a lot of attention because they can present stereoscopic images without the need for special equipment.

[0003] Some display machines have poor support structure flexibility, making it difficult to adjust the height and stability according to different ground conditions and display needs. In addition, the holographic projection screen, as the core component of the display machine, is relatively fragile and easily damaged by external collisions, scratches and other damages. Some existing display machines lack effective protective structures. In order to solve the above problems, this utility model provides a naked-eye 3D display machine. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a naked-eye 3D display machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A naked-eye 3D display machine includes a main body and a holographic projection screen. The main body has sleeve rods fixedly connected to its four corners. Two fixing plates are fixedly connected to the upper ends of both sides of the main body. Threaded screws are rotatably connected to the inside of the fixing plates via bearings. Support rods are threaded onto the surface of the threaded screws. Mounting frames are fixedly connected to the front and back of the main body. Movable plates are movably connected inside the mounting frames. Protective components are fixedly connected to the upper ends of the movable plates.

[0007] As a further improvement of this utility model, the protective component includes a first protective plate fixedly connected to the upper end of the movable plate. The first protective plate has grooves on both sides, and a sliding plate is movably connected inside each of the two grooves. A second protective plate is hinged to one side of the sliding plate, and a magnetic suction plate is provided on the other side of the second protective plate. A limit block is fixedly connected to the upper end of the sliding plate.

[0008] As a further improvement of this utility model, gripping rings are fixedly connected to both sides of the upper surface of the first protective plate.

[0009] As a further improvement of this utility model, the support rod is movably connected to the sleeve rod, and the lower ends of the four support rods are all fixedly connected to a base.

[0010] As a further improvement of this utility model, a handle is fixedly connected to the upper end of the threaded screw, and the holographic projection screen is fixedly connected to the middle of the upper surface of the machine body.

[0011] As a further improvement of this utility model, four casters are fixedly connected to the lower surface of the machine body, and inspection doors are provided on both sides of the machine body.

[0012] The beneficial effects of this utility model are:

[0013] By incorporating protective components, the casters facilitate the movement of the equipment during use. By rotating the handle at the top of the threaded screw, the height of the support rod within the sleeve is adjusted, allowing the base to contact the ground and stably support the equipment. This enables a quick transition from a mobile to a stable placement state, ensuring the equipment remains stable during presentations and providing reliable assurance for the stable operation of the holographic projection screen. Furthermore, the support rod's height can be adjusted via the threaded screw and sleeve, flexibly adjusting the overall height and stability of the equipment according to different ground conditions and presentation needs. This adapts to various complex environments and enhances the presentation effect.

[0014] By incorporating protective components, during use, pulling the movable plate upwards raises the first protective plate, then pulling the slide plate out of the groove unfolds the second protective plate. The magnetic plate on the second protective plate, in conjunction with other components, allows the first and second protective plates to jointly enclose the holographic projection screen. This effectively prevents the holographic projection screen from physical damage such as collisions and scratches when not in use, and also blocks dust and debris from entering the screen area, extending the lifespan of the holographic projection screen and reducing maintenance costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Referring to Figures 1-4, a naked-eye 3D display machine includes a body 1 and a holographic projection screen 8. Each of the four corners of the body 1 is fixedly connected with a sleeve rod 2. Each of the upper ends of both sides of the body 1 is fixedly connected with two fixing plates 3. The inside of the fixing plates 3 is rotatably connected with a threaded screw 4 through a bearing. The surface of the threaded screw 4 is threaded with a support rod 5. The front and back of the body 1 are fixedly connected with mounting frames 6. The inside of the mounting frames 6 is movably connected with a movable plate 7. The upper end of the movable plate 7 is fixedly connected with a protective component.

[0022] In this utility model, the protective component includes a first protective plate 9 fixedly connected to the upper end of the movable plate 7. Both sides of the first protective plate 9 are provided with sliding grooves 10, and sliding plates 11 are movably connected inside the two sliding grooves 10. One side of the sliding plate 11 is hinged to a second protective plate 12, and the other side of the second protective plate 12 is provided with a magnetic suction plate 13. The magnetic suction plate 13 can ensure that when the second protective plate 12 is unfolded, it can be tightly attracted to the other side of the second protective plate 12 or other compatible structures to form a stable protective structure, and it will not be difficult to separate due to excessive magnetism, which facilitates subsequent storage operations. The upper end of the sliding plate 11 is fixedly connected to a limiting block 19, and both sides of the upper surface of the first protective plate 9 are fixedly connected to gripping rings 14. The limiting block 19 can prevent the sliding plate 11 from sliding out of the sliding groove 10 of the first protective plate 9.

[0023] Support rod 5 is movably connected to sleeve rod 2. The movable connection between support rod 5 and sleeve rod 2 ensures that support rod 5 can move smoothly up and down within sleeve rod 2 to adjust the height of the equipment, and also maintains stability after adjustment to ensure that the equipment is placed securely. The lower ends of the four support rods 5 are all fixedly connected to bases 15, and the upper ends of threaded screws 4 are fixedly connected to handles 16. The surface of handles 16 is provided with anti-slip texture to increase the friction of handles 16 and prevent slippage. Holographic projection screen 8 is fixedly connected to the middle of the upper surface of the machine body 1. The machine body 1 can project clear holographic images into the holographic projection screen 8. The lower surface of the machine body 1 is fixedly connected to four casters 17. There are four casters 17. Both sides of the machine body 1 are provided with maintenance doors 18. The four casters 17 are evenly distributed in the four corners of the lower surface of the machine body 1, making the equipment easier and more convenient to move.

[0024] In use, the device is moved to the desired display position via the casters 17. Once in position, the handle 16 fixedly connected to the upper end of the threaded rod 4, which is rotatably connected to the bearing inside the fixed plate 3, is rotated. This rotation causes the support rod 5 to move up and down along the sleeve 2, thus adjusting the height of the support rod 5. This ensures that the base 15 contacts the ground and stably supports the equipment, guaranteeing stable placement. When the device is not in use, the gripping rings 14 fixedly connected to both sides of the upper surface of the first protective plate 9 are grasped, and the first protective plate 9 is pulled upwards. When the first protective plate 9 rises to a suitable position, the slide plate 11 is pulled out from the slide groove 10. Since the second protective plate 12 is hinged to one side of the slide plate 11, the second protective plate 12 can be rotated and unfolded around the hinge. After the second protective plate 12 is unfolded, the magnetic plate 13 on its other side can attract the corresponding part of the unfolded second protective plate 12, so that the second protective plate 12 and the first protective plate 9 work together to surround the holographic projection screen 8 fixedly connected to the middle of the upper surface of the body 1, thereby protecting the holographic projection screen 8.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
