[0029] like Figure 1 and Figure 2 As shown, a multimedia exhibition hall lifting device provided by the utility model includes a base plate 1, an arc-shaped display screen 111 located below the base plate 1 and penetrating the base plate 1, a gear track 2 located below the display screen 111 and connected symmetrically to the transmission gear 112 through a transmission gear 112, a frame 116 is sleeved on the outside of the display screen 111, a connecting rod 113 is connected to the side of the frame 116 close to the gear track 2, and a limit block 114 is located on the other side of the connecting rod 113, a groove 115 corresponding to the limit block 114 is provided inside the transmission gear 112, an adjusting groove 3 is connected to the side of the gear track 2 away from the transmission gear 112, the gear track 2 includes a track sub-component 212 connected by a first connecting member 211, the adjusting groove 3 includes a groove sub-component 312 connected by a second connecting member 311, and the side of the adjusting groove 3 away from the gear track 2 is connected to a corresponding threaded rod 314 through a plurality of connecting rings 313.

[0030] In this embodiment, a gear track 2 and an adjustment groove 3 are provided which can change their length and shape with the aid of a first connecting member 211 and a second connecting member 311, thereby changing the travel trajectory of a transmission gear 112 located between the adjustment groove 3 and the gear track 2. The transmission gear 112 in turn drives the display screen 111 to move, thereby changing the height of the display screen 111 relative to the base plate 1, and the rotation of the position angle.

[0031] like Figure 3 , 4 As shown in Figure 5, the middle of the track sub-component 212 and the first connecting member 211 are respectively provided with a through groove 213 that penetrates through themselves and corresponds to the transmission gear 112, the interior of the two ends of the track sub-component 212 is provided with a first sliding groove 214 for the first connecting member 211 to slide, and the two ends of the first connecting member 211 are connected to a circular first rotating member 215 corresponding to the first sliding groove 214, the interior of the groove sub-component 312 is provided with a limiting groove 315 for the second connecting member 311 to slide inside, and the two sides of the inner wall of the limiting groove 315 are provided with a second sliding groove 316, and the two ends of the second connecting member 311 are provided with a second rotating member 215 corresponding to the second sliding groove 316. The rotating member 317, one end of the first sliding groove 214 and the second sliding groove 316 are circular grooves corresponding to the first rotating member 215 and the second rotating member 317 respectively, the two ends of the track sub-member 212 and the groove sub-member 312 are respectively provided with notches corresponding to the first connecting member 211 and the second connecting member 311, the bottom of the threaded rod 314 is connected to the motor 318, the other end of the threaded rod 314 is connected to the limiting member 319, the side of the connecting ring 313 close to the adjusting groove 3 is connected to the connecting plate 321 through the connecting column 320, and the end of the connecting plate 321 close to the adjusting groove 3 is connected to the limiting rod 322 corresponding to the limiting groove 315.

[0032] In this embodiment, a motor 318 is set to drive the threaded rod 314 to rotate, so that the two connecting rings 313 can rise or fall as a whole. By changing the length of the threaded rod 314, the size of the single ring can be changed. The figure is only a schematic diagram of the principle. By changing the position of the connecting ring 313 at the corresponding position, the position of the gear track 2 and the adjustment groove 3 relative to other parts can be driven. After the gear track is rotated through the existing technology (refer to the chain transmission), the transmission gear 112 can be driven to move along the track.

[0033] It should be noted that all track sub-components 212 and groove sub-components 312 are arc-shaped and can form a circular overall track as shown in the figure after being connected together.

[0034] When in use, first start the motors 318 at different positions according to the predetermined trajectory, and drive the connecting ring 313 to rise or fall through the threaded rod 314. The connecting ring 313 is connected to the limiting rod 322 corresponding to the limiting groove 315 by means of the connecting column 320 and the connecting plate 312, thereby driving the groove sub-component 312 at the corresponding position and the track sub-component 212 connected to the groove sub-component 312 to rise or fall. Taking the gear track 2 as an example, when the track sub-component 212 is offset, the internal first connecting member 211 will slide to the position of the circular groove of the first rotating member 215 sliding to the first sliding groove 214, so that the first rotating member 215 can rotate in the first sliding groove 214, driving the first connecting member 211 to rotate and deviate at the notch on the track sub-component 212, so that the gear track 2 is bent as a whole, and the adjusting groove 3 is the same. Therefore, when the gear track 2 rotates, it will drive the transmission gear 112 to move in the specified track, thereby achieving rising or falling, and at the same time it will roll forward to rotate at an angle. The utility model has a simple structure and is easy to use.

[0035] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
