Description

Technical Field

[0001] This utility model relates to the field of server rack technology, specifically to a bottom height adjustable mechanism for server racks. Background Technology

[0002] Existing server racks typically have a single flat base. To install a height-adjustable mechanism, holes need to be drilled at the four corners of the flat plate, and then threaded sleeves are welded to the corresponding holes. Adjustable studs are then threaded through the holes and inserted into the sleeves, ensuring the adjustment mechanism is reliably installed at its corresponding position on the bottom plate. However, in practice, this type of adjustment mechanism, which is only mounted on the base plate, requires additional support. Since the base plate also needs to accommodate casters in addition to the adjustment mechanism, a thicker base plate is necessary to ensure reliable support for the entire server rack. The weight is relatively large and the overall manufacturing cost is high. In practical applications, the height-adjustable stud needs to be retracted to the upper position of the caster when it rolls, which requires a certain amount of height space to be reserved at the top of the adjustable stud. However, the existing structure of the flat plate combined with the screw sleeve has a pre-set upper protruding screw sleeve on the upper surface of the bottom plate. This can easily lead to spatial limitations during server equipment assembly, making it impossible to fully and reliably utilize the internal cavity of the server rack. Therefore, there is an urgent need to develop a bottom height-adjustable mechanism that reduces the weight of the server rack and ensures that the upper layer of the bottom plate can reliably utilize the cavity. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a bottom height adjustable mechanism for server racks, which reduces the overall weight of the server rack and ensures that the upper layer of the bottom plate is a reliably usable cavity.

[0004] The adjustable bottom height mechanism of the server rack is characterized in that it includes:

[0005] A sheet metal base frame includes an upper plate, a pair of first side edges, and another pair of second side edges. The two long sides of the upper plate are respectively provided with downwardly folded first side edges. The middle of the length direction of the first side edges is provided with an inwardly folded support connecting edge. The two short sides of the upper plate are respectively provided with oppositely folded second side edges. The bottom of the second side edges also includes an inwardly extending end frame plate. The end frame plate is connected to the corresponding position of the first side edges through a positioning stop.

[0006] Four stud support seats, each stud support seat includes a stud and a bottom support seat;

[0007] And four caster wheel assemblies, which include mounting plates and casters;

[0008] A connecting plate is provided between the two ends of the supporting connecting edge of the first side perimeter of the two sets of the first side perimeter. The universal wheel connecting plate corresponding to the four corner positions is fixedly installed on the corresponding positions of the connecting plate and the end side frame plate. The mounting plate is fixed to the universal wheel connecting plate by connecting bolts. The universal wheel is set facing downward.

[0009] The end frame plate is provided with clearance holes at the four corners corresponding to the entire base frame. A threaded sleeve is welded in the space between each clearance hole and the upper plate. Each upper plate is provided with a through notch at the top of the threaded sleeve. The stud of the stud support passes through the clearance hole and is threaded to the inner thread hole of the threaded sleeve.

[0010] Its further features are:

[0011] The bottom of the base plate frame is also provided with a reinforcing frame structure on both sides corresponding to the length direction. The reinforcing frame structure includes a connecting plate, a first connecting side, a transition support connecting plate, and a second connecting side. The second connecting side is covered by the side space formed by the end frame plate and the upper plate. The universal wheel connecting plate is fixedly installed in the space between the second connecting side and the connecting plate.

[0012] Each set of stud support seats corresponds to a connecting screw sleeve seat. The connecting screw sleeve seat includes a screw sleeve mounting plate and a screw sleeve. One end of the screw sleeve mounting plate is mounted with a protrusion and fixed to the corresponding positioning hole groove on the second connecting side. The other end of the screw sleeve mounting plate is fixed to the lower surface of the end side frame plate by a fastening screw. The upper surface of the screw sleeve mounting plate is in close contact with the lower surface of the end side frame plate. The screw sleeve is arranged corresponding to the position of the clearance hole, which ensures that the screw sleeve is installed externally. The screw sleeve connecting seat can be quickly assembled by positioning installation, ensuring convenient and quick assembly.

[0013] The stud is provided with a hexagonal drive end at the top. The top of the stud can be directly driven by a wrench at the through-notch position to complete the height adjustment of the bottom support.

[0014] By adopting the structure of this utility model, the original thick steel plate is replaced with a thin steel plate sheet metal combination mechanism, which makes the lifting area of ​​the stud located in the height area between the upper plate and the end frame plate. The stud does not need to be exposed on the upper plate during the adjustment process, and it reduces the weight of the entire server rack, while ensuring that the upper part of the bottom plate is a reliably usable cavity.
