Technical Field

[0001] The utility model relates to the technical field of cabinet installation, in particular to a vertical height adjustment device for a metal cabinet. Background Art

[0002] When installing a traditional cabinet, it is necessary to install plastic or metal adjusting feet at the bottom of the cabinet to adjust the vertical height of the cabinet. The bottom of the adjusting feet has a certain vertical height, which will cause a certain gap between the cabinet and the ground, which will reduce the height space inside the cabinet. After the cabinet is assembled, it is also necessary to install a skirting board in front of the bottom of the cabinet to ensure beauty and avoid dust accumulation.

[0003] The adjusting foot has a vertical height adjustment function. When you want to adjust the height, you need to remove the skirting board. At the same time, due to the limited space on the bottom of the cabinet, you may need to lift the cabinet before manual adjustment, which is inconvenient to a certain extent. In addition, when lifting or moving the cabinet, the adjusting foot is likely to scratch the floor.

[0004] Furthermore, the adjusting feet of the metal cabinet not only have the above-mentioned disadvantages, but also the entire adjusting feet are exposed to the outside, are relatively large in size, and are easily damaged by bumps. Summary of the invention

[0033] Please refer to Figures 1 to 10 , the utility model provides a vertical height adjustment device for a metal cabinet.

[0034] like Figure 1 As shown, the metal cabinet includes a first metal cabinet 1, which is formed by bending sheet metal inward, and four bending strips 11 are provided on the side of the first metal cabinet 1, and a receiving cavity is provided inside; a vertical height adjustment device 2 is installed on the side of the first metal cabinet 1, and the vertical height adjustment device 2 can be fixed to the side of the first metal cabinet 1 by bolts; the vertical height adjustment device 2 can also be fixed to the side of the first metal cabinet 1 by other fixing parts.

[0035] like Figure 1 As shown, the vertical height adjustment device 2 includes an internal base 3 installed inside the first metal cabinet 1 and an invisible adjustment foot 4 installed on the internal base 3. The internal base 3 and the invisible adjustment foot 4 cooperate with each other to adjust the vertical height of the first metal cabinet 1; a second through hole 12 is provided on the first metal cabinet 1; the end of the invisible adjustment foot 4 away from the internal base 3 passes through the second through hole 12 and contacts the ground.

[0036] In this embodiment, if Figure 1As shown, the first metal cabinet 1, the built-in base 3 and the invisible adjusting foot 4 are placed vertically, and the side of the invisible adjusting foot 4 is provided with an adjusting bolt 41 for adjusting the vertical height of the invisible adjusting foot 4. Correspondingly, the side of the built-in base 3 and the first metal cabinet 1 are both provided with a first through hole 31 corresponding to the adjusting bolt 41, so as to facilitate the height adjustment of the first metal cabinet 1 from the side. Figure 5 As shown; in this embodiment, the adjusting bolt 41 is a hexagon socket adjusting bolt, which is driven by a hexagon socket wrench; according to the actual situation, it can be assumed that when the hexagon socket rotates clockwise, the vertical height of the invisible adjusting foot 4 increases; when the hexagon socket rotates counterclockwise, the vertical height of the invisible adjusting foot 4 decreases.

[0037] When adjusting the height, the hexagonal wrench is sequentially passed through the first through hole 31 on the side of the first metal cabinet 1 and the first through hole 31 on the built-in base 3, inserted into the adjusting bolt 41, and rotated clockwise together with the adjusting bolt 41. At this time, the vertical height of the invisible adjusting foot 4 is increased, and the built-in base 3 is vertically lifted. At the same time, since the built-in base 3 is fixedly connected to the first metal cabinet 1, the first metal cabinet 1 is also vertically lifted; when the first metal cabinet 1 needs to be vertically lowered, the hexagonal wrench can be rotated counterclockwise; the utility model can adjust the vertical height of the first metal cabinet 1 from the side, and the operation is simple and convenient.

[0038] Furthermore, to adjust the height from the side, you only need to bend over to operate, and there is no need to move the metal cabinet. The exposed invisible adjustment feet will not scratch the floor.
