[0027] The following further describes the present application in conjunction with the attached Figures 1-3 drawings and specific embodiments:

[0028] First of all, it should be noted here that in the description of this application, when terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and other orientation words appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings. It is only for the convenience of description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to this application; in addition, when terms such as "first", "second", "third" and other numerical quantifiers appear, they are only for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in this application, unless otherwise clearly specified and limited, when terms such as "installation", "connection", "connection" appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an interference fit, a transition fit and other limit connections, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium; therefore, for those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] As Figures 1 to 3 shown, a vertical lifting platform includes: a first platform 2, four electric cylinders 3 and a second platform 4. Through holes 21 are opened at the four corners of the first platform 2; each electric cylinder 3 includes a cylinder body 31 and an output shaft 32. A first mounting plate 5 is fixed on the cylinder body 31. The first mounting plate 5 is detachably mounted on the first platform 2. A second mounting plate 6 is fixed to the end of the output shaft 32. The second mounting plate 6 can pass through the through hole 21; the second platform 4 is arranged below the first platform 2. The second mounting plate 6 is detachably mounted on the second platform 4.

[0030] In this application, when the vertical lifting platform works, the four electric cylinders 3 act synchronously. The output shafts 32 of the electric cylinders 3 perform telescopic movements. The second mounting plate 6 at the end of the output shaft 32 is connected to the second platform 4 to drive the second platform 4 to perform vertical lifting movement relative to the first platform 2. The first mounting plate 5 fixes the cylinder body 31 of the electric cylinder 3 on the first platform 2 to ensure the stability of the entire lifting process.

[0031] The four electric cylinders 3 are respectively located at the four corners of the first platform 2 and can provide uniform supporting force for the platform to ensure the smooth and reliable lifting process. Both the first mounting plate 5 and the second mounting plate 6 adopt detachable mounting methods. When the electric cylinder 3 fails and needs to be maintained or replaced, the disassembly and installation operations can be carried out conveniently. During installation, the first platform 2 and the second platform 4 can be stacked together, and then the second mounting plate 6 is fixed on the second platform 4. Then, the stroke of the electric cylinder 3 is shortened and the first mounting plate 5 is moved to the first platform 2, and then the first mounting plate 5 is fixed on the first platform 2. During installation, it can be installed from top to bottom, which is convenient for installation.

[0032] Specifically, the cylinder body 31 of the electric cylinder 3 is perpendicular to the first mounting plate 5 .

[0033] The cylinder body 31 of the electric cylinder 3 is perpendicular to the first mounting plate 5, so that the electric cylinder 3 can more stably withstand the pressure from the first platform 2 and the load above when working. This vertical structural relationship ensures that the force transmission is more direct and efficient, reduces the additional stress caused by angle deviation, and thus greatly improves the structural stability of the entire vertical lifting platform.

[0034] Specifically, the first mounting plate 5 can cover the through hole 21, and the first mounting plate 5 is connected to the first platform 2 via four first bolts, the four first bolts are distributed around the through hole 21, and the first bolts are installed on the first platform 2 from top to bottom.

[0035] The first mounting plate 5 is connected to the first platform 2 through four first bolts distributed around the through hole 21, and the first bolts are installed from top to bottom on the first platform 2. This installation method is very convenient, and the operator can easily install and remove the bolts above the platform without having to perform complicated operations below the platform, which greatly improves the efficiency of installation and maintenance.

[0036] Specifically, the output shaft 32 is connected to the second mounting plate 6 via a floating joint 7 .

[0037] The output shaft 32 is connected to the second mounting plate 6 via the floating joint 7, which can effectively compensate for errors that may occur between the output shaft 32 and the second mounting plate 6 during installation and operation.

[0038] Specifically, the second mounting plate 6 is connected to the second platform 4 via four second bolts, and the second bolts are installed on the second platform 4 from top to bottom.

[0039] The second bolt is installed on the second platform 4 from top to bottom, making the installation and removal process more convenient and quick. The operator can easily tighten and loosen the bolt above the platform without having to perform complicated operations below the platform, thereby improving the efficiency of installation and maintenance.

[0040] Specifically, a fence 8 is fixed on the first platform 2 , the fence 8 is configured to block the electric cylinder 3 , and the fence 8 is provided with an inlet 81 and an outlet 82 .

[0041] During the use of the vertical lifting platform, especially in the application scenarios combined with AR technology, users may ignore the surrounding environment due to focusing on the virtual experience. The setting of the fence 8 can effectively prevent people from accidentally falling from the edge of the platform, providing important safety protection for users. The fence 8 blocks the electric cylinder 3, preventing users from contacting moving parts such as the electric cylinder 3 during activities, and further reducing the risk of accidental accidents.

[0042] It should be noted that the above embodiments are only used to illustrate the present application and do not limit the technical solutions described in the present application. Although this specification has described the present application in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the art can still modify the present application or make equivalent replacements, and all technical solutions and their improvements that do not depart from the spirit and scope of the present application should be covered within the scope of the claims of the present application.
