[0036] The specific use process of the device is as follows: during the transportation and transfer of the device, at this time, the side baffle one 6 and the side baffle two 7 are in a vertical state under the action of the bottom linkage assembly, and the side baffle one 6 and the side baffle two 7 and the butt joint plate 8 are butt jointed together with the protective shell 13, thereby forming a protective cover on the outside of the device to protect the device from damage; when the device is transported to the destination and needs to be used, at this time, the motor 39 is started, the motor 39 drives the driving sprocket 38 to rotate, the driving sprocket 38 drives the chain 36 to rotate in turn, and the chain 36 drives the synchronous sprocket 35 to rotate synchronously, the synchronous sprocket 35 drives the bidirectional screw rod 30 to rotate, the bidirectional screw rod 30 rotates in turn to drive the coaxially connected nut moving seat one 27 and nut moving seat two 74 to move synchronously, the nut moving seat one 27 and the nut moving seat two 74 move to the two sides respectively, the upward movement of the nut moving seat one 27 will drive the protective shell 13 to move upward and thereby expose the upper part of the support frame 2, at the same time as the upward movement of the nut moving seat one 27, the gear 33 on the side of the nut moving seat one 27 will walk on the rack plate 34, the walking of the gear 33 will drive the winding roller 32 to rotate through the rotating shaft 31, the rotation of the winding roller 32 will gradually wind the traction rope one 23, the traction rope one 23 will be wound in the protective shell 13 in the upward state and will pull the moving plate 22 to move in the direction of the butt joint hole 14, the movement of the moving plate 22 will extrude and push the inclined edge of the movable plate 15, thereby driving the movable plate 15 to rotate, and finally when the protective shell 13 completes the upward movement, the movable plate 15 rotates to a vertical state, and the display screen 17 and the elastic sealing strip 18 on the side of the movable plate 15 will be sealed in the butt joint hole 14; during the above-mentioned rotation of the winding roller 32 to wind the traction rope one 23, because a part of space is reserved in the inner cavity 73 for the excess extension of the stacked traction rope one 23, therefore, before the moving plate 22 moves vertically out of the groove 40, only the excess extension of the wound traction rope one 23 will be wound, and the moving plate 22 will not be pulled to move, when the subsequent upward movement of the moving plate 22 is operated, the wound traction rope one 23 will pull the moving plate 22 to move horizontally, at this time, the moving plate 22 will move to push the movable plate 15 to rotate.When the nut moving seat 2 74 moves downward, it will cause the U-shaped plate 5 to descend. At this time, under the gravity of the counterweight plate 46, counterweight block 49, and connecting plate 47, the traction rope 2 75 is in a taut state, so that the side baffle 1 6 and side baffle 2 7 are in a vertical state with the U-shaped plate 5. As the U-shaped plate 5 descends, it will drive the counterweight plate 46, counterweight block 49, and connecting plate 47 to descend vertically through the taut traction rope 2 75. When the connecting plate 47 descends to the bottom of the vertical groove 43, the U-shaped plate 5 will continue to descend to the bottom of the movable groove 25, where it has not yet descended. As the U-shaped plate 5 continues to descend, the traction rope When the 23 is in the extended state, the side baffles 6 and 7, which were originally vertical at the top of the U-shaped plate 5, will rotate to a horizontal state of 90 degrees. Furthermore, the side baffles 6 and 7 will overlap and stabilize on the top of the base 3. Simultaneously, the storage slots 10 on the top of the side baffles 6 and the connecting plate 8 can hold promotional materials for easy viewing by exhibitors. The touchscreen 9 on the side baffle 7 facilitates interaction for exhibitors. When the U-shaped plate 5 descends to the inner bottom of the U-shaped groove 4, the support legs 42 at the bottom of the U-shaped plate 5 also extend to the bottom of the base 3 and contact the ground, thus aligning the base 3... The casters at the bottom lift up, providing stable support for the device. Before and after the operation of the aforementioned protective support mechanism, a limiting mechanism needs to be activated to release and lock the bottom linkage components. Specifically, an electric push rod 55 can move the push block 56, which in turn moves the inclined block 53. The movement of the inclined block 53 simultaneously moves the horizontal plate 50, which in turn moves the protrusion 64 via the push plate 63. The protrusion 64 then presses against the inclined groove 62 on the inner wall of the push groove 61, thereby pushing... The moving sliding seat 51 moves to drive the locking block 71 from the groove 4 into the cavity. The moving horizontal plate 50 will drive the inclined block 53 on the side to squeeze and push the adjacent fixed block 52. Then, through the four sets of mutually contacting fixed blocks 52 and inclined blocks 53, the four horizontal plates 50 will move synchronously to realize the synchronous storage action of the four locking blocks 71. After the groove plate 5 has moved, the pressure on the inclined block 53 is released. Under the action of the second spring 60, the horizontal plate 50 resets and moves to push the locking block 71 into the groove 4 to lock and fix the groove plate 5.The limiting mechanism has a manual driving mode in addition to the above-mentioned electric mode. The manual driving mode is used when the electric push rod 55 is damaged or fails, so that the limiting mechanism can still be used. That is, the horizontal plate 50 is pulled outward by pulling the handle 67, and the movement of the horizontal plate 50 drives the push plate 63 and the inclined block 53 to realize the above-mentioned movement of the sliding seat 51 and the clamping block 71, and the linkage movement of the four sets of fixed blocks 52 and the inclined block 53. The handle 67 is moved outward into the limiting groove 72. At this time, the end of the connecting block 65 is connected with the end of the handle 67. Then, the handle 67 is rotated from the horizontal state to the vertical state. Then, the handle 67 is moved upward, and the middle part of the handle 67 is connected with the connecting block 65. At the same time, the sliding shaft 66 at the end of the connecting block 65 is clamped in the positioning groove 70 on the inner wall of the track groove 69. Finally, the handle 67 is loosened, and the handle 67 is transversely moved and clamped in the limiting groove 72 under the action of the spring 2 60. Although the handle 67 and the horizontal plate 50 are partially reset under the action of the spring 2 60, the influence on the clamping block 71 is small, and the part of the clamping block 71 penetrating into the back-shaped groove 4 can still be clamped left and right.
