[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4This utility model provides a splicable LED holographic interactive stereoscopic display screen, including a base 1, a support column 2, an adjustment mechanism 3, a fixing frame 4, a display module 5, a splicing mechanism 6, and a back plate 7. The support column 2 is fixedly connected to the top of the base 1, the adjustment mechanism 3 is disposed inside the support column 2, the fixing frame 4 is disposed above the adjustment mechanism 3, the display module 5 is disposed inside the fixing frame 4, the splicing mechanism 6 is disposed on the back of the display module 5, and the back plate 7 is disposed on the back of the display module 5.

[0024] The splicing mechanism 6 consists of a protrusion 601, a cross block 603, a positioning block 604, a push plate 605, a second spring 606, and a concave block 607. The protrusion 601 is fixedly connected to one side of the back of the display module 5. A cross groove 602 is symmetrically opened on the back of the protrusion 601. The cross block 603 is slidably connected to the inside of the cross groove 602. The positioning block 604 is fixedly connected to the side of the cross block 603 near the outer surface of the protrusion 601. The second spring 606 is fixedly connected between the other side of the cross block 603 and the side of the cross groove 602.

[0025] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the recess 607 is fixedly connected to the back of the display module 5. The internal space of the recess 607 is adapted to the size of the protrusion 601. The two sides of the recess 607 are symmetrically provided with positioning grooves 608 that are adapted to the positioning block 604.

[0026] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the push plate 605 is fixedly connected to the back of the cross block 603, and the push plate 605 is evenly provided with anti-slip grooves on its outer side, and the positioning block 604 is provided with a slope on the side near the concave block 607.

[0027] By using the inclined surface, when the positioning block 604 is inserted into the recess 607, it is pressed, causing the positioning block 604 to retract into the cross groove 602, making it easier for the protrusion 601 to be installed into the recess 607.

[0028] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the back plate 7 is fixedly connected to the back of the fixing frame 4 by bolts, and heat dissipation slots are symmetrically opened on the back plate 7.

[0029] The heat dissipation channels allow for heat dissipation during the use of the display module 5, ensuring its normal operation.

[0030] As can be seen from the above working process, the splicing mechanism 6 can quickly splice the display screen 5 and has high-precision positioning and adjustment functions, which can ensure that the splicing gap between each module is minimized, improve the overall aesthetics and display effect of the display screen, and the splicing operation is relatively simple and convenient, improving the ease of use and flexibility of splicing.

[0031] Further as Figure 1 and Figure 2 As shown, it is worth noting that the adjusting mechanism 3 consists of a connecting column 301, a fixed tooth block 303, a connecting rod 305, a baffle 306, a connecting plate 307, a limiting tooth block 308, and a first spring 309. A limiting groove 302 is provided inside the support column 2. The connecting column 301 is slidably connected to the inside of the limiting groove 302. The fixed frame 4 is fixedly connected to the top surface of the connecting column 301. A groove 304 is provided on the right side of the limiting groove 302. The connecting rod 305 is slidably connected between the groove 304 and the outer wall of the support column 2. The baffle 306 is fixedly connected to one end of the connecting rod 305, and the connecting plate 307 is fixedly connected to the other end of the connecting rod 305.

[0032] Further as Figure 1 and Figure 2 As shown, it is worth noting that the fixing tooth block 303 is uniformly fixedly connected to the right side of the connecting column 301, and the limiting tooth block 308 is fixedly connected to the left side of the connecting plate 307. The fixing tooth block 303 and the limiting tooth block 308 have the same size but different inclined plane directions.

[0033] Further as Figure 1 and Figure 2 As shown, it is worth noting that the first spring 309 is symmetrically and fixedly connected between the side of the connecting plate 307 and the groove 304, and a handle is fixedly provided on the outside of the baffle 306.

[0034] When the height of the display module 5 needs to be lowered, pull the handle, and the connecting rod 305 will slide to the right through the baffle 306. Then, the limiting tooth block 308 will be moved into the groove 304 through the connecting plate 307, releasing the limitation on the fixed tooth block 303. The connecting column 301 can then move down inside the limiting groove 302 to complete the height adjustment of the display module 5.

[0035] The protrusion 601 and the concave block 607 are set separately. The protrusion 601 is set on the back of one of the display modules 5, and the concave block 607 that matches the protrusion 601 is set on the back of another display module 5 connected to it or on the side of the fixing frame 4.

[0036] This solution has the following working process: In use, firstly, the protrusion 601 on the back of one display screen is inserted into the recess 607 on the back of another display screen. The opening of the recess 607 presses against the inclined surface of the positioning block 604, tightening the interior of the protrusion 601 until the protrusion 601 is fully inserted into the interior of the recess 607. At this time, under the elastic action of the second spring 606, the cross block 603 is reset, and the positioning block 604 is moved to insert into the positioning groove 608. The positioning block 604 fixes the connection between the protrusion 601 and the recess 607, thus completing the splicing of the two display screens. This step can then be used to splice the remaining display screens, which can also complete the connection and installation of the display module 5 and the fixing frame 4. The operation is relatively convenient. Finally, the back plate 7 is installed on the back of the fixing frame 4 with bolts to complete the installation of the main body of the display screen.

[0037] When adjusting the height of the display module 5, simply pull the fixing frame 4 upwards. The connecting post 301 slides inside the limiting groove 302, and the fixing tooth block 303 moves upwards to press against the inclined surface of the limiting tooth block 308, causing the limiting tooth block 308 to move into the groove 304, thus avoiding obstruction of the movement of the connecting post 301. This completes the height adjustment of the display module 5. After adjustment, the elastic action of the first spring 309 drives the connecting plate 307 to reset, causing the limiting tooth block 308 to insert between the fixing tooth blocks 303. The horizontal surface of the limiting tooth block 308 blocks the horizontal surface of the fixing tooth block 303, fixing the height of the connecting post 301, thus completing the height adjustment.

[0038] In summary: The splicing mechanism 6 enables rapid splicing of the display screen 5, with high-precision positioning and adjustment functions. This ensures minimal gaps between modules, enhancing the overall aesthetics and display effect of the screen. The splicing operation is also simple and convenient, improving ease of use and flexibility. Furthermore, the support column 2 and adjustment mechanism 3 allow for height adjustment of the display screen 5, catering to different user needs, reducing visual fatigue, improving interaction, adapting to various interactive scenarios, and better accommodating different installation environments, thus increasing space utilization.
