By employing high-precision imaging, dynamic data rendering, and intelligent interactive systems, exhibits are presented in three-dimensional suspension and can be controlled in real time. Visitors can interact with virtual scenes through gesture recognition and touch controls, and the combination of multi-sensory feedback (such as sound and light linkage) enhances the realism of the experience. Widely used in science and technology exhibitions, educational demonstrations, and commercial displays, holographic projection technology overcomes the limitations of traditional displays by offering low latency and high compatibility, giving content a dynamic, contextualized, and intelligent innovative expression. Holographic sand tables are a common display device in holographic projection exhibition halls.

[0003] The existing technology has the following shortcomings: The existing technology disclosed in CN216052446U includes "an exhibition hall curtain wall, a holographic light strip, and a rotating mechanism for driving the holographic light strip to rotate; the exhibition hall curtain wall has a cavity, the holographic light strip and the rotating mechanism are both set in the cavity, and the cavity also has an L-shaped support frame, the longitudinal end of the support frame is vertically downward and is slidably connected to the exhibition hall curtain wall through a sliding component, the rotating mechanism is set at the end of the transverse end of the support frame, and the front and rear side walls of the exhibition hall curtain wall are provided with observation windows of the same size, the projections of the two observation windows facing each other coincide, and the observation windows are located within the rotation boundary of the holographic light strip".

[0004] The aforementioned structure significantly enhances the realism of holographic image viewing by displaying only the image within the viewing window's field of vision when the holographic light strip rotates, while all other structures are hidden within the cavity. However, this structure uses a traditional fixed display method, which results in significant blind spots and poor display effects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a device for enhancing the effects of holographic projection in exhibition halls, solving the problem of poor display effects in fixed locations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a holographic projection exhibition hall effect enhancement device, including a main support, a power button, a support platform and a glass cover.

An inward groove is formed at the middle end on the outer side of the main body bracket.

[0010] As a preferred technical solution of the present utility model, the displacement adjustment frame further includes positioning balls, a large gear ring, a direction-changing gear, a bearing bracket, a middle shaft, and a linkage gear. There are eight groups of positioning balls, which are movably connected between the displacement adjustment frame and the main body bracket.

[0011] As a preferred technical solution of the present utility model, the large gear ring is fixedly installed on the inner end face of the displacement adjustment frame. The middle of the direction-changing gear is provided with a shaft structure and is movably connected to the side end of the bearing bracket through this shaft structure.

[0012] As a preferred technical solution of the present utility model, the bearing bracket is sleeved around the middle shaft. The middle shaft penetrates through the bearing bracket and is movably connected to the middle of the bearing mounting seat at the bottom. The tooth grooves of the linkage gear are engaged with the direction-changing gear and are penetrated by the middle shaft.

[0013] As a preferred technical solution of the present utility model, the top of the middle shaft is inserted into the middle of the support platform, and the positioning balls are embedded inside the limiting groove.

[0014] As a preferred technical solution of the present utility model, a semi-circular inner groove structure is formed at the position where the limiting groove contacts the positioning balls. An "L"-shaped grip structure is further provided on the outer side of the displacement adjustment frame.

[0015] Compared with the prior art, the present utility model provides a device for enhancing the effect in a holographic projection exhibition hall, having the following beneficial effects:

[0016] A device for enhancing the effect in a holographic projection exhibition hall. By providing a displacement adjustment frame, a limiting groove, a bearing mounting seat, a direction-changing gear, a large gear ring, and a linkage gear, when the device is in use, the operator controls the projector through the power button. When a holographic image appears inside the glass cover by the projector, it can be externally displayed. If the operator needs to adjust the display angle, the displacement adjustment frame can be rotated through the grip structure on the outer side of the displacement adjustment frame. During the rotation of the displacement adjustment frame, the large gear ring inside it rotates synchronously and drives the direction-changing gear meshed with it to rotate. At the same time, the direction-changing gear drives the linkage gear to rotate. Since there is a connection relationship between the linkage gear and the middle shaft, and the support platform is also connected to the middle shaft, when the middle shaft rotates, it synchronously drives the top support platform, the glass cover, and the projector to rotate. During this process, the eight groups of positioning balls rotate simultaneously in the limiting groove;

[0017] Through the aforementioned settings and processes, the projected subject of this device can be rotated at any angle during use. Compared to current fixed-position holographic projection display sand tables and other similar equipment, this significantly improves display flexibility, thereby reducing blind spots and enhancing the display effect.

[0023] 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.

[0024] In this implementation plan: a holographic projection exhibition hall effect enhancement device includes a main support 1, a power button 2, a support platform 3 and a glass cover 4. The power button 2 is located on the side of the main support 1, the support platform 3 is located above the main support 1, the glass cover 4 is located on the upper end of the support platform 3, and a projector 5 is located on the upper end of the support platform 3.

[0025] A displacement adjustment frame 6 is installed at the lower end of the support platform 3.

[0026] The main support 1 also includes a limiting groove 101 and a bearing mounting seat 102. The limiting groove 101 is opened at the top of the main support 1, and the bearing mounting seat 102 is fixedly installed at the bottom of the inside of the main support 1.

[0027] In this embodiment, the limiting groove 101 is integrally in the structure of a circular arc groove and is annularly distributed on the top of the main body bracket 1. An inward groove is provided at the middle end of the outer side of the main body bracket 1. The displacement adjustment frame 6 further includes positioning balls 601, a large gear ring 602, a direction-changing gear 603, a bearing bracket 604, a middle shaft 605, and a linkage gear 606. Eight groups of positioning balls 601 are provided and are movably connected between the displacement adjustment frame 6 and the main body bracket 1.

[0028] Specifically, as Figure 1 and Figure 2 shown, the eight groups of positioning balls 601 are installed between the main body bracket 1 and the displacement adjustment frame 6, which can reduce the friction between the main body bracket 1 and the displacement adjustment frame 6 when the displacement adjustment frame 6 rotates, thereby reducing wear and improving the service life of the equipment.

[0029] In this embodiment, the large gear ring 602 is fixedly installed on the inner end face of the displacement adjustment frame 6. A shaft structure is provided in the middle of the direction-changing gear 603, and it is movably connected to the side end of the bearing bracket 604 through this shaft structure. The bearing bracket 604 is sleeved on the periphery of the middle shaft 605. The middle shaft 605 penetrates through the bearing bracket 604, and the bottom is movably connected to the middle of the bearing mount 102. The tooth groove of the linkage gear 606 meshes with the direction-changing gear 603 and is penetrated by the middle shaft 605.

[0030] Specifically, as Figure 3 and Figure 4 shown, when the large gear ring 602 rotates, it drives the linkage gear 606 to rotate through the direction-changing gear 603, thereby controlling the angle adjustment of the support table by the middle shaft 605.

[0031] In this embodiment, the top of the middle shaft 605 is inserted into the middle of the support table 3, and the positioning balls 601 are embedded in the inner side of the limiting groove 101. The limiting groove 101 is provided with a semi-circular inner groove structure at the position where it contacts the positioning balls 601. A "C"-shaped handle structure is further provided on the outer side of the displacement adjustment frame 6.

[0032] The working principle and usage process of the present utility model: When the device is in use, the operator controls the projector 5 through the power button 2. When the projector 5 presents a holographic image inside the glass cover 4, it can be externally displayed. If the operator needs to adjust the display angle, the displacement adjustment frame 6 can be rotated through the handle structure on the outer side of the displacement adjustment frame 6. During the rotation of the displacement adjustment frame 6, the large gear ring 602 on its inner side rotates synchronously and drives the direction-changing gear 603 meshing with it to rotate. At the same time, the direction-changing gear 603 drives the linkage gear 606 to rotate. Since there is a connection relationship between the linkage gear 606 and the middle shaft 605, and the support table 3 is also connected to the middle shaft 605, when the middle shaft 605 rotates, it synchronously drives the top support table 3, the glass cover 4, and the projector 5 to rotate. During this process, the eight groups of positioning balls 601 rotate simultaneously in the limiting groove 101.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
