[0024] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] Depend on Figures 1 to 5 The utility model comprises a box body 1, a fixed platform 2 is arranged in the box body 1, a movable first display screen 3, a second display screen 4 and a third display screen 5 are installed on the fixed platform 2, and the second display screen 4 and the third display screen 5 form a connected display screen with the first display screen 3 after unfolding;

[0027] A lifting assembly is provided in the box body 1, and the lifting assembly is connected to the fixed table 2 to control the lifting and lowering of the fixed table 2 and the display screen. The lifting assembly includes two guide rails 6 arranged opposite to each other in the box body 1, and two first sliders 7 are slidably installed in one of the guide rails 6, and the upper ends of the two first sliders 7 are connected to the lower end surface of the fixed table 2. The lifting assembly also includes at least one first hydraulic cylinder 8, and the upper and lower ends of the first hydraulic cylinder 8 are respectively connected to the lower end of the fixed table 2 and the lower end of the inner cavity of the box body 1. The up and down movement of the first hydraulic cylinder 8 can drive the fixed table 2 to rise and fall, thereby controlling the height of the display screen so that viewers can have a better viewing experience, and the stability of the up and down movement of the fixed frame can be improved by limiting the guide rails 6 and the first sliders 7.

[0028] In order to enable the display screen to be flipped to obtain a multi-directional viewing position, a limit stopper 9 is provided on the guide rail 6, and a matching stopper 10 that matches the position of the limit stopper 9 is provided on the first slider 7, so that after the first slider 7 rises to a certain height, the limit stopper 9 contacts the matching stopper 10 to prevent the first slider 7 from continuing to move upward, and a through groove can be provided on the box body 1 and the guide rail 6, and a limit rod can be inserted into the through groove to adjust the limit height;

[0029] The upper ends of the two first sliding blocks 7 are respectively hinged to the front and rear sides of the lower end surface of the fixed platform 2 through hinge seats. The lower end of the fixed platform 2 is provided with a slide rail 11 corresponding to the position of the first hydraulic cylinder 8. The upper end of the first hydraulic cylinder 8 is provided with a horizontal rotating shaft, which is slidably installed in the slide rail 11, so that when the fixed platform 2 is turned over, the first hydraulic cylinder 8 can still drive the fixed platform 2 to move up and down;

[0030] Since the fixed platform 2 cannot be flipped due to the cooperation between the first slider 7 and the guide rail 6, one of the first sliders 7 includes an upper slider 71 and a lower slider 72. The upper end of the lower slider 72 has a groove, and a rotating shaft is rotatably installed in the groove. A first telescopic rod 73 is rotatably installed on the rotating shaft through a rotating sleeve. The upper end of the first telescopic rod 73 is fixedly connected to the lower end of the upper slider 71, and a stop block 10 is installed on the lower slider 72.

[0031] The fixed platform 2 is provided with a control mechanism for connecting or separating the first display screen 3, the second display screen 4 and the third display screen 5. The control mechanism includes two first support frames 12 and two second support frames 13. The two first support frames 12 are respectively mounted on the front and rear ends of the left side of the fixed platform 2, and the two second support frames 13 are respectively mounted on the front and rear ends of the right side of the fixed platform 2. The first support frame 12 and the second support frame 13 can be fixed to the fixed platform 2 by bolts, or can be directly fixed by conventional means such as welding of connecting parts. The specific fixing method is not limited. The first display screen 3, the second display screen 4 and the third display screen 5 are sequentially mounted in the first support frame 12 and the second support frame 13 from top to bottom. A partition plate 14 is installed on the fixed plate, and at least one first support seat is installed on one side of the partition plate 14, and at least one second support seat is installed on the other side of the partition plate 14. The first support seat is fixedly mounted with a second extension seat. The telescopic rod 15 and the end of the second telescopic rod 15 are provided with a first bracket 16, the upper end of the first bracket 16 is fixedly connected to the lower end of the second display screen 4, and the third telescopic rod 17 is fixedly installed on the second support seat, and the end of the third telescopic rod 17 is provided with a second bracket 18, the upper end of the second bracket 18 is fixedly connected to the lower end of the third display screen 5. Since there is a height difference between the first display screen 3 and the second display screen 4, the first bracket 16 and the second bracket 18 have the same height difference. One of the second telescopic rods 15 and one of the third telescopic rods 17 are hydraulic cylinders, thereby driving the second display screen 4 to move rightward and the third display screen 5 to move leftward respectively through the two hydraulic cylinders, and the second display screen 4 and the third display screen 5 are still connected to the second telescopic rod 15 and the third telescopic rod 17 through the first bracket 16 and the second bracket 18 when moving, so as to ensure the stability of the first bracket 16 and the second bracket 18.

[0032] In order to facilitate the distinction and positioning of the first display screen 3, the second display screen 4 and the third display screen 5 during installation, the first support frame 12 includes a support column 121, and a card plate 122 is installed at the upper and lower ends of the support column 121. The area between the card plates 122 constitutes an installation groove 123. The second support frame 13 has the same structure as the first support frame 12, except that a first limit block 124 is installed on one side of the middle layer of the installation groove 123 of the first support frame 12, and a second limit block is installed on one side of the lower layer of the installation groove 123 of the second support frame 13. 125, the first limit block 124 and the second limit block 125 are respectively located on two opposite sides of the mounting groove 123, the first display screen 3 is installed on the upper side of the mounting groove 123, the second display screen 4 is installed on the middle side of the mounting groove 123 and one end of the second display screen 4 contacts with the side of the first limit block 124 close to the center of the mounting groove 123, the third display screen 5 is installed on the lower side of the mounting groove 123 and one end of the third display screen 5 contacts with the side of the second limit block 125 close to the mounting groove 123, and the first display screen 3, the second display screen 4 and the third display screen 5 are installed and positioned through the first support frame 12 and the second support frame 13.

[0033] Since only the second display screen 4 and the third display screen 5 are slid left and right for display, there will be a gap between the first display screen 3, the second display screen 4 and the third display screen 5, which affects the viewing experience. The first bracket 16 includes an upper bracket 161 and a lower bracket 162. A connecting rod is installed at the lower end of the upper bracket 161, and a mounting hole is installed on the lower bracket 162. The connecting rod is slidably installed in the mounting hole. A first connecting plate 163 is installed at the lower end of the lower bracket 162, and a second connecting plate 164 is installed at the lower end of the upper bracket 161. A second hydraulic cylinder 19 is installed on the first connecting plate 163, and the upper end of the second hydraulic cylinder 19 is connected to the first connecting plate 163. When the second display screen 4 and the third display screen 5 are completely slid out, the second hydraulic cylinder 19 drives the second display screen 4 and the third display screen 5 to rise to the same level as the first display screen 3, thereby improving the viewing experience.

[0034] Since the second hydraulic cylinder 19 can only drive one end of the second display screen 4 and the third display screen 5 to rise, this will make the other end of the second display screen 4 and the third display screen 5 unstable. At least one first groove 20 is provided at the lower end of the second display screen 4 and the third display screen 5, and a third hydraulic cylinder 21 and a fourth hydraulic cylinder 22 corresponding to the position of the first groove 20 are provided on both sides of the fixed plate. The upper end of the third hydraulic cylinder 21 extends into the first groove 20 of the second display screen 4, and the upper end of the fourth hydraulic cylinder 22 extends into the first groove 20 of the third display screen 5. The third hydraulic cylinder 21 and the fourth hydraulic cylinder 22 rise and fall simultaneously with the second hydraulic cylinder 19 on the adjacent side.

[0035] The upper ends of the third hydraulic cylinder 21 and the fourth hydraulic cylinder 22 are provided with rotating rollers, which can reduce the friction between the third hydraulic cylinder 21 , the fourth hydraulic cylinder 22 and the second display screen 4 and the third display screen 5 .

[0036] The first display screen 3, the second display screen 4 and the third display screen 5 may all be frameless screens, touch screens or a combination thereof.

[0037] When the utility model is in use, under normal circumstances, the first display screen 3 maintained horizontally can be directly used, and the height of the first display screen 3 can be adjusted by the first hydraulic cylinder 8 to cope with different viewers' close-up viewing, and it can also be convenient to operate; when the digital model to be displayed or the control system needs a larger display space, the first hydraulic cylinder 8 can be raised to the fixed plate to leave the inner cavity of the box body 1, and then the second display screen 4 and the third display screen 5 are driven to move to the two sides of the first display screen 3 respectively by the first telescopic rod 73 and the second telescopic rod 15, when the second display screen 4 and the third display screen 5 are not overlapped with the first display screen 3, After folding, the third hydraulic cylinder 21 and the fourth hydraulic cylinder 22 are controlled to extend simultaneously, so as to control the second display screen 4 and the third display screen 5 to be flush with the first display screen 3; when the display screen needs to be tilted or erected to facilitate viewing by multiple people, the first hydraulic cylinder 8 can be raised until the limit block 9 contacts the matching block 10, and when the first hydraulic rod continues to rise, the end on which the normal first slider 7 is installed will be limited and stop rising, while the end on which the first telescopic rod 73 is installed will continue to move upward, so that the fixed plate and the first display screen, the second display screen 4 and the third display screen 5 are flipped, and the display on the screen can be viewed from a distance.

[0038] The beneficial effects of the utility model are:

[0039] 1. The heights of the first display screen 3, the second display screen 4 and the third display screen 5 can be easily adjusted by the first hydraulic cylinder 8. This design can adapt to the sight requirements of viewers of different heights, ensuring that viewers can view the display screens at a comfortable angle, thereby improving the viewing experience;

[0040] 2. When a larger display space is needed to present a digital model or a control system, after the first hydraulic cylinder 8 raises the first display screen 3 to an appropriate position, the first and second telescopic rods 15 can smoothly move the second and third display screens 5 to both sides of the first display screen 3 to form a wider continuous display surface, which is suitable for displaying some large models;

[0041] 3. The extension of the third and fourth hydraulic cylinders 22 can ensure that the three display screens remain flush, thereby providing a seamless visual experience. This flexibility enables the system to be quickly adjusted according to different display requirements.

[0042] 4. When the display screen needs to be tilted or erected for more people to watch or display, the fixed plate and the three display screens can be smoothly flipped to the required angle by the continued rise of the first hydraulic cylinder 8. This design greatly enhances the usability and viewing range of the display screen, is simple and efficient, and is particularly suitable for large-scale events, conferences or exhibitions.
