[0025] By adopting the above technical solution, the hydraulic cylinder 4 has a strong adaptability to load and environmental changes, which can avoid shaking during the lifting process and improve the stability of the lifting.

[0026] Reference Figure 1 The frame 1 is provided with a plurality of moving wheels, through which the overall movement is facilitated. The frame 1 is provided with a plurality of parking components 5, through which the frame 1 is parked at a certain point to prevent the frame 1 from moving during lifting.

[0027] Reference Figure 2 The parking assembly 5 includes a hydraulic cylinder 501 installed on the frame 1. The lower end of the hydraulic cylinder 501 is hinged with an anti-skid plate 502 through a damping shaft. The anti-skid plate 502 is driven to move by the hydraulic cylinder 501 to make the anti-skid plate fit with the ground support to prevent the frame 1 from deflecting.

[0028] Reference Figure 2The scissor-type folding frame 301 is composed of a plurality of mutually hinged hinged units, wherein the hinged unit includes two hinged rods hinged to each other in the middle, the frame 1 and the lifting platform 2 are respectively hinged to the corresponding hinged rods, and a slide groove is installed on the side where the frame 1 and the lifting platform 2 are close to each other, and the two connecting rods 302 are respectively slidably installed in the corresponding slide grooves.

[0029] Reference Figure 3 The adjustment component 6 includes a bidirectional screw 601 rotatably mounted on the frame 1, and two movable plates 603 are respectively threadedly sleeved on the two ends of the bidirectional screw 601. The two ends of the bidirectional screw 601 pass through the lifting platform 2 and are connected with a screw handle. The bidirectional screw 601 is rotated by turning the screw handle to adjust the position of the movable plate 603. Guide rods 602 are installed at both ends of the bidirectional screw 601 on the lifting platform 2, and the guide rods 602 slide through the two movable plates 603.

By adjusting the angle and position of the connecting plate 701, the pressing plate 703 is located above the display board, and then the threaded rod 702 is screwed to fix the display board.

[0031] The implementation principle of a stable lifting device for booth construction in the embodiment of the present application is as follows:

[0032] Before the lifting process, in order to prevent the lifting platform 1 from moving, the extension and contraction of the hydraulic cylinder 2 501 can be controlled to drive the anti-slip plate 502 to fit with the ground support to achieve a stationary parking;

[0033] Then, the exhibition board is fixed. After the lifting platform 2 reaches a predetermined height, the two-way screw 601 of the adjusting assembly 6 can be rotated to move the movable plate 603 to an appropriate position. Then, the pressing plate 703 is driven down by screwing the threaded rod 702 to fix the exhibition board on the movable plate 603. In this process, the position and angle of the movable plate 603 and the pressing force of the pressing plate 703 can be adjusted to fix exhibition boards of different sizes and shapes.

[0034] Then, the display board is lifted to the designated position, and the scissor-type folding frame 301 is driven to unfold and fold by operating the extension and contraction of the hydraulic cylinder 4, thereby driving the lifting platform 2 to lift. In this process, since the hydraulic cylinder 4 has a strong adaptability to changes in load and environment, the lifting platform 2 can remain stable during the lifting process to avoid shaking.
