[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This embodiment provides a splicing large screen lifting system suitable for mobile cabins. It is installed on the side wall of the mobile cabin to realize the lifting of the splicing large screen, which facilitates the splicing of the large screen and saves manpower and time.

[0030] like Figures 1-4 As shown, the lifting system includes: frame 1, linear actuator, connecting frame 3, guide rail 5, limiting component 6, and splicing screen frame 14.

[0031] As an example, the linear actuator uses an electric cylinder 2, which is a linear electric cylinder whose actuating end is capable of linear motion.

[0032] Frame 1 is installed on the side wall of the mobile modular container. Frame 1 is a frame structure surrounded by left and right side frames, a bottom connecting beam 11, and a top connecting beam. The left and right side frames are vertically facing L-shaped plates. To improve the strength of frame 1, reinforcing ribs, namely reinforcing rib I4 and reinforcing rib II8, are provided at the right angles of the L-shaped plates on both sides. In addition, a bottom connecting plate 9 for the electric cylinder is provided on the top frame beam of frame 1, and a side connecting frame 10 for the electric cylinder is provided on the side frame. The cylinder body of electric cylinder 2 is installed on frame 1 through the bottom connecting plate 9 and the side connecting frame 10. The bottom connecting beam 11 is connected to the chassis of the modular container.

[0033] A guide rail 5 is vertically installed on each of the left and right sides of the frame 1; two sliders slide on each guide rail 5; and limiters 6 are provided at the upper and lower ends of each guide rail 5 to limit the vertical movement of the connecting frame 3. Installation work is carried out at the lower limit position and screen projection work is carried out at the upper limit position.

[0034] The connecting frame 3 is used to install the splicing screen frame 14. The connecting frame 3 slides with the frame 1 and can move up and down along the frame 1. The connecting frame 3 includes: a connecting frame body 32 and screen connecting flanges 31, slider connecting flanges 33 and electric cylinder connecting flanges 34, which are provided on the connecting frame body 32. Slider connecting flanges 33 are provided on both sides of the crossbeam in the connecting frame body 32, which are used to cooperate with the sliders on the corresponding side guide rails 5, thereby allowing the connecting frame 3 to be installed on the guide rails 5 through the slider connecting flanges 33. The actuating end of the electric cylinder 2 is equipped with a floating joint 7. The actuating end of the electric cylinder 2 is vertically downward and connected to the electric cylinder connecting flange 34 through the floating joint 7, so that when the actuating end of the electric cylinder 2 extends or retracts, it can push the connecting frame 3 to move up and down along the guide rails 5. Screen connecting flanges 31 are also provided on both sides of the crossbeam in the connecting frame body 32 for connection with the splicing screen frame 14.

[0035] The splicing frame 14 is used for the installation of splicing large screens, including: screen connecting frame 13 and screen connecting frame connecting beam 12; several screen connecting frames 13 arranged horizontally at intervals are connected into a whole by the screen connecting frame connecting beam 12 arranged on the back; the screen connecting frame connecting beam 12 is fixed to the connecting frame 3 by the screen connecting flange 31.

[0036] As an example, the large screen frame 14 includes four horizontally spaced screen connecting frames 13, which have a grid structure. The screen connecting frames 13 are connected as a whole by at least three connecting beams 12. The connecting beams 12 are divided into upper, middle, and lower beams according to their position; the number of beams can be increased depending on the number of screens. Furthermore, the screen connecting flanges 31 are divided into upper and lower rows (each row has three screen connecting flanges 31) according to their position, corresponding to the upper and middle beams respectively.

[0037] The working process of the above-mentioned splicing large screen lifting system applicable to mobile cabins is as follows:

[0038] When installing a large video wall, first extend the electric cylinder 2 and lower the connecting frame 3 as needed. Figure 6 The lowest position shown is (i.e., the position of the lower limiting component); then assemble the splicing screen frame 14 and install the splicing screen frame 14 with the connecting frame 3; then install the splicing screen unit onto the screen connecting frame 13, at which point the installation of the splicing screen is completed; control the electric cylinder 2 to retract, and the connecting frame 3 drives the splicing screen to rise to the lowest position shown ... Figure 5 The highest position (i.e., the position of the upper limiting component) is reached; at this point, the screen can be projected and activities can begin. After the activities are completed, the splicing screen is lowered to its lowest position for disassembly and packing. After disassembly, the electric cylinder 2 is retracted.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
