Description

Technical Field

[0001] The utility model relates to the technical field of holographic display cabinets, in particular to a holographic display cabinet which utilizes an LED light source to project a transparent holographic film for imaging. Background Art

[0002] Holographic display cabinet is an advanced display technology that can present the holographic image of an object to the audience. This display method is not only high-tech, but also can present a very realistic effect. Therefore, it has been widely used in museums, exhibition halls, education industry, shopping malls and various trade fairs.

[0003] Due to light source issues, traditional holographic display cabinets are often relatively large. Using compact semiconductor lasers as light sources, however, has limited luminous power, making it difficult to achieve the required performance. However, the emergence of new LED light sources, with coherence lengths comparable to semiconductor lasers, offers high luminous power in a compact size, addressing these challenges. Holographic display cabinets can be significantly reduced in size, while light source power is increased, resulting in even more ideal displays. Therefore, in existing technology, holographic display cabinets typically use LED light sources.

[0004] According to a Chinese patent document with publication number CN208207517U, a conical multimedia holographic display cabinet is disclosed, in which a motor is used to move a round box back and forth, thereby adjusting the angle of the display cabinet and making it more convenient for viewers to watch.

[0005] However, the height of the above-mentioned display cabinets cannot be freely adjusted. If the height is too high, it is not convenient for children to view, while if the height is too low, it is not convenient for adults to view. At the same time, the display cabinets lack braking measures and are easily moved by external forces. Therefore, a holographic display cabinet that uses LED light sources to project images on transparent holographic films is proposed. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a holographic display cabinet that uses an LED light source to project transparent holographic film imaging includes a base 1 and a mounting base 3. A mounting frame 5 is fixedly installed on the upper end of the mounting base 3, and a transparent holographic film body 4 is fixedly installed on the mounting frame 5. The base 1 is located below the mounting base 3, and a lifting mechanism is provided between the mounting base 3 and the base 1. The lifting mechanism consists of a lifting frame 2, a guide rod 7, an adjusting screw 8 and a motor 12. The lifting frame 2 is fixedly connected to the bottom of the mounting base 3, and four guide rods 7 are all fixedly installed on the upper end of the base 1. The four guide rods 7 are distributed at the four corners of the upper surface of the base 1. The upper ends of the guide rods 7 are slidably inserted into the bottom of the lifting frame 2. The adjusting screw 8 is rotatably installed in the middle of the upper end of the base 1. The upper end of the adjusting screw 8 is inserted into the bottom of the lifting frame 2 and is connected to the lifting frame 2 by threaded fitting. The motor 12 is provided at the lower extension position of the adjusting screw 8, and the motor 12 is fixedly embedded in the bottom of the base 1.

[0023] When in use, the motor 12 is energized, and the motor 12 can drive the adjusting screw 8 to rotate. The lifting frame 2 is restricted by the four guide rods 7 and cannot rotate. When the adjusting screw 8 rotates, the lifting frame 2 will move along the axial direction of the adjusting screw 8, thereby controlling the height of the lifting frame 2 and the transparent holographic film body 4. The height of the display cabinet can be adjusted according to different exhibits. For example, the height of the transparent holographic film body 4 can be lowered for exhibits for children, and the height of the transparent holographic film body 4 can be raised for exhibits for adults, thereby making the display cabinet suitable for more people.

[0024] Among them, four universal wheels 9 are provided at the bottom of the base 1, and the four universal wheels 9 are respectively distributed at the four corners of the bottom of the base 1.

[0025] The universal wheels 9 can facilitate the movement and transportation of the display cabinet.

[0026] Among them, a fixed sleeve 10 is provided on the outside of the universal wheel 9, and the fixed sleeve 10 is fixedly connected to the bottom of the base 1. A lifting sleeve 11 is inserted into the inside of the fixed sleeve 10, and the outer wall of the lifting sleeve 11 is connected to the inner wall of the fixed sleeve 10 through threaded cooperation.

[0027] During use, rotating the lifting sleeve 11 can drive the lifting sleeve 11 to move up and down in the fixed sleeve 10, controlling the lifting sleeve 11 to move downward so that the bottom of the lifting sleeve 11 contacts the ground, thereby having a braking effect on the display cabinet.

[0028] The inner diameter of the lifting sleeve 11 is larger than the diameter of the movable range of the universal wheel 9 .

[0029] Such an arrangement can ensure that no interference occurs between the lifting sleeve 11 and the universal wheel 9.

[0030] The bottom of the lifting sleeve 11 is frosted.

[0031] Such an arrangement can increase the friction between the bottom of the lifting sleeve 11 and the ground.

[0032] A protective cover 6 is provided on the outside of the mounting frame 5 , and a slot 13 is provided on the edge of the upper surface of the mounting seat 3 to be slidably engaged with the bottom of the protective cover 6 .

[0033] The protective cover 6 is provided to protect the transparent holographic film body 4 when the display cabinet is not in use.

[0034] Among them, four support columns 14 are fixedly connected between the bottom of the mounting frame 5 and the mounting base 3.

[0035] The support columns 14 can improve the stability of the mounting frame 5 and the transparent holographic film body 4.

[0036] The utility model provides a holographic display cabinet that uses LED light sources to project transparent holographic film images. The specific working principle is as follows:

[0037] When in use, the motor 12 is energized, and the motor 12 can drive the adjusting screw 8 to rotate. The lifting frame 2 is restricted by the four guide rods 7 and cannot rotate. When the adjusting screw 8 rotates, the lifting frame 2 will move along the axial direction of the adjusting screw 8, thereby controlling the height of the lifting frame 2 and the transparent holographic film body 4. The height of the display cabinet can be adjusted according to different exhibits. For example, the height of the transparent holographic film body 4 can be lowered for things displayed to children, and the height of the transparent holographic film body 4 can be raised for things displayed to adults, thereby making the display cabinet suitable for more people. The universal wheels 9 can facilitate the movement and transportation of the display cabinet. By rotating the lifting sleeve 11, the lifting sleeve 11 can be driven to move up and down in the fixed sleeve 10, and the lifting sleeve 11 is controlled to move downward so that the bottom of the lifting sleeve 11 contacts the ground, thereby having a braking effect on the display cabinet.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
