[0033] The present invention will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 1-4 As shown, a mobile inverter for computer rooms includes a mounting housing 1. A support structure is provided at the bottom of the mounting housing 1. The support structure includes a mounting groove 11 formed in the bottom of the mounting housing 1. A first support frame 12 and a second support frame 13 are mounted in the mounting groove 11. A folding assembly 2 is connected between the first support frame 12 and the second support frame 13. A rolling support and a fixed support 14 are mounted at the bottom of the second support frame 13. The rolling support includes a plurality of support rollers 38. The fixed support 14 includes a longitudinally arranged mounting column 15. A support column 16 capable of lifting and lowering is mounted at the bottom of the mounting column 15. A bottom support plate 19 is mounted at the bottom of the support column 16.

[0035] Under normal circumstances, the folding assembly 2 between the first support frame 12 and the second support frame 13 in the support structure is in a folded state, that is, the first support frame 12 and the second support frame 13 are close together and retracted into the mounting base groove 11, and the support column 16 of the fixed support member 14 extends to support the ground; when movement is required, the folding assembly 2 between the first support frame 12 and the second support frame 13 in the support structure is in an unfolded state, and then the support column 16 of the fixed support member 14 retracts, and the support roller 38 of the rolling support member contacts the bottom surface, thereby realizing movement without manual lifting, and can be used in multiple areas.

[0036] Specifically, the fixed support 14 also includes a longitudinal movable hole 17 formed longitudinally in the mounting column 15, and a longitudinal threaded sleeve 18 is sleeved inside the longitudinal movable hole 17. The support column 16 is formed with an external thread structure that is threadedly engaged with the longitudinal threaded sleeve 18. When it is necessary to contact the bottom surface for support, the support column 16 is rotated, and the external thread structure is threadedly engaged with the longitudinal threaded sleeve 18 to realize the lifting movement, so that the bottom support plate 19 at the bottom of the support column 16 contacts the bottom surface.

[0037] Specifically, the rolling support also includes a roller shaft 39 installed between two coaxially spaced support rollers 38. The roller shaft 39 enables the two coaxially arranged support rollers 38 to move synchronously, thereby improving the stability of the movement.

[0038] Specifically, the folding component 2 includes a first movable strip 21 and a second movable strip 22. The middle ends of the first movable strip 21 and the second movable strip 22 are rotatably connected, and the connection point is the central connection point 23. The first movable strip 21 and the second movable strip 22 are movably connected to form an X-shaped structure. The first movable strip 21 and the second movable strip 22 can swing around the central connection point 23, thereby realizing the folding or unfolding of the folding component 2.

[0039] Furthermore, the bottom of the first support frame 12 is provided with a top first hinge shaft 24 and a top second hinge shaft 25, wherein the top of the first movable bar 21 is rotatably connected to the top first hinge shaft 24, and the top of the second movable bar 22 is rotatably connected to the top second hinge shaft 25. The bottom of the second support frame 13 is provided with a bottom first hinge shaft 26 and a bottom second hinge shaft 27, wherein the bottom of the first movable bar 21 is formed with a first bottom connecting hole 28, and the bottom of the second movable bar 22 is formed with a second bottom connecting hole 29. The first bottom connecting hole 28 is fitted onto the bottom first hinge shaft 26, and the bottom second hinge shaft 27 is fitted onto the bottom second hinge shaft 27. When the first movable bar 21 and the second movable bar 22 can swing around the central connection point 23, the distance between the first support frame 12 and the second support frame 13 changes, thereby realizing the folding or unfolding of the overall support structure.

[0040] Furthermore, there are two folding components 2. A first transverse connecting rod 33, a second transverse connecting rod 34, and a third transverse connecting rod 35 are provided between the two folding components 2. The first transverse connecting rod 33 is connected between the two first movable bars 21, the second transverse connecting rod 34 is connected between the two second movable bars 22, and the third transverse connecting rod 35 is connected to the center connection point 23 of the two folding components 2. Under the action of multiple transverse connecting rods, the two sets of folding components 2 work simultaneously, which further improves the support stability of the first support frame 12 and the second support frame 13.

[0041] The second support frame 13 is equipped with a bottom drive mechanism 3 that drives the first movable bar 21 and the second movable bar 22 to swing around the central connection point 23. The bottom drive mechanism 3 includes an electric push rod 31 and a drive rod 32 installed at the output end of the electric push rod 31. One end of the drive rod 32 is rotatably connected to the first transverse connecting rod 33. The body of the electric push rod 31 is rotatably installed on the second support frame 13. When the electric push rod 31 extends, the angle between the first movable bar 21 and the first support frame 12 increases, and at the same time, the angle between the first movable bar 21 and the second support frame 13 increases. At this time, it is in the unfolded state, and the mounting housing has a large clearance from the ground, which facilitates movement. Conversely, when the electric push rod 31 retracts, the angle between the first movable bar 21 and the second support frame 13 decreases, and the distance between the first support frame 12 and the second support frame 13 decreases until the bottom support plate 19 at the bottom of the support column 16 contacts the bottom surface.

[0042] The second support frame 13 is also provided with a fourth transverse connecting rod 36 parallel to the first transverse connecting rod 33. The fourth transverse connecting rod 36 is equipped with a hinge seat 37. The body of the electric push rod 31 is mounted on the hinge seat 37. When the electric push rod 31 is driven to extend and retract, the whole body will swing, so it can swing adaptively in conjunction with the hinge seat 37.

[0043] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0044] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
