Description

Technical Field

[0001] This utility model relates to the technical field of communication equipment installation accessories, specifically to an adjustable base for network cabinets. Background Technology

[0002] In communication equipment rooms and related equipment installation scenarios, the rack base, as the core supporting component of the rack, directly affects the installation stability and usability of the rack. Traditional rack bases generally adopt a fixed height design, which has obvious application limitations: First, when the installation ground is uneven, the rack cannot be leveled by adjusting the base itself; second, for scenarios that require reserving space for bottom cabling or adjusting the rack's height from the ground according to equipment heat dissipation requirements, fixed height bases are difficult to meet the requirements; third, if a fine adjustment of the height of a traditional base is required, it can only be achieved by adding shims to the bottom, and the adjustment range is usually only about 5mm, resulting in low adjustment precision. Furthermore, it cannot lower the rack, severely limiting its applicability. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and provide an adjustable base for network cabinets. This device should have the characteristics of reasonable design, convenient adjustment and strong stability.

[0004] The technical solution of this utility model is: An adjustable base for a network cabinet includes a base fixed to the ground, a platform located above the base for supporting the cabinet, and a lifting mechanism for adjusting the height of the platform. The lifting mechanism is fixed at the four corners of the base and the platform respectively; the lifting mechanism includes a base support fixed to the base at the bottom end, a platform support fixed to the platform at the top end and slidably positioned in the base support at the bottom end, a lifting screw fixed to the base at the bottom end and extending upward into the platform support at the top end, and a lifting nut meshing with the lifting screw.

[0005] The lifting mechanism also includes a locking groove formed on the side wall of the base support, a locking hole formed on the side wall of the platform support, a locking bolt passing through the locking groove and the locking hole, and a locking nut engaging with the locking bolt.

[0006] Both the base support and the platform support have U-shaped cross-sections; the locking groove is formed on the two side wing plates of the base support; the locking hole is formed on the two side wing plates of the platform support; and the bottom of the platform support is provided with an end plate.

[0007] The bottom end of the lifting screw is fixed to the base via a foot cup; the top end of the lifting screw passes upward through the end plate.

[0008] The platform has connection holes on its side.

[0009] It also includes floor rails; the floor rails are horizontally fixed to the side of the platform by fasteners installed in the connection holes.

[0010] The two adjacent platforms are secured by fasteners installed in the connection holes.

[0011] The beneficial effects of this utility model are: This utility model improves the structure of the traditional cabinet base by optimizing the integral base into a split structure of the base and platform, and then uses a lifting mechanism to make fine adjustments to the height, which effectively solves the problem of cabinet installation height adaptation caused by special on-site installation conditions (such as uneven ground, insufficient wiring space, etc.). Enhanced adjustability: Compared to the traditional base with a micro-adjustment range of only about 5mm, this utility model can achieve a wide range of height adjustment of ±50mm, which can not only meet the need for increasing height, but also lower the height according to the needs of the scene, adapting to more installation environments; Improved construction efficiency: When cables or pipes need to be laid at the bottom of the cabinet, the base can be fixed to the ground first, and then the pipes can be laid on the fixed base. Finally, the platform can be installed, avoiding the mutual interference between the cable laying and the base fixing when installing the traditional base, which significantly improves the on-site construction efficiency. Wide range of applications: This utility model can be widely applied to the construction and renovation projects of computer rooms of telecommunications operators such as China Telecom, China Unicom, China Mobile, China Broadcasting Network, and China Tower. It can meet the diverse needs of cabinet installation in the process of intelligent development of network communication and has high practical value and promotion prospects.

Detailed Implementation

[0023] To enable those skilled in the art to better understand and implement this utility model, the technical solution of this utility model is described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.

[0024] like Figure 1 As shown, an adjustable base for a network cabinet includes a base 1, a platform 2, a lifting mechanism, and a floor shelf 11. The base is fixed to the ground, the platform is located above the base to support the cabinet, and the lifting mechanism is disposed between the base and the platform to adjust the height of the platform.

[0025] The base is a frame structure, comprising two parallel base crossbeams 1.1, two base longitudinal beams 1.2 and one base reinforcing longitudinal beam 1.3 fixed perpendicularly to the base crossbeams. The base reinforcing longitudinal beam is located between the two base longitudinal beams, with both ends fixed to the middle of the base crossbeams. The length of the base longitudinal beam is greater than the spacing between the base crossbeams. Both ends of the base crossbeam are fixed to the base longitudinal beam, and both ends of the base longitudinal beam extend beyond the base crossbeam. Fixing holes 1.4 are formed in the extended parts of the base longitudinal beam for installing expansion bolts to firmly fix the base to the ground foundation. The cross-sections of the base crossbeams and the base reinforcing longitudinal beam are L-shaped, and the cross-sections of the base longitudinal beam are U-shaped, with the openings of the base longitudinal beam facing upwards.

[0026] The platform is a frame structure, comprising two parallel platform crossbeams 2.1, two platform longitudinal beams 2.2 and one platform reinforcing longitudinal beam 2.3 fixed perpendicularly to the platform crossbeams. The platform longitudinal beam is located directly above the base longitudinal beam, and the platform longitudinal beam, platform reinforcing longitudinal beam, and base longitudinal beam are of equal length. The platform crossbeams are of equal length to the base crossbeams, the spacing between the platform crossbeams is equal to the length of the base longitudinal beam, and the ends of the platform crossbeams are fixed to the ends of the platform longitudinal beams. This structure ensures that during side-by-side installation, the upper platforms can lock into each other, while the lower bases do not interfere with each other.

[0027] The platform reinforcing longitudinal beam is located between the two platform longitudinal beams, and its two ends are fixed to the middle of the platform crossbeam. Both the platform crossbeam and the platform reinforcing longitudinal beam have L-shaped cross-sections, while the platform longitudinal beams have U-shaped cross-sections, with the openings of the platform longitudinal beams facing downwards.

[0028] The lifting mechanism comprises four components, which are fixed at the four corners of the base and the platform. Each lifting mechanism includes a base support column 3, a platform support column 4, a lifting screw 5, a lifting nut 6, a locking groove 3-1, a locking hole 4-1, a locking bolt 7, and a locking nut 8.

[0029] The base supports are arranged vertically, and their bottom ends are fixed to the base (at the connection between the base crossbeam and the base longitudinal beam). The cross-section of each base support is U-shaped, and the opening of the base support faces the base crossbeam on the other side. The locking grooves are formed on the two side flanges of the base supports.

[0030] The platform supports are arranged vertically, with their tops fixed to the platform's longitudinal beams. Each platform support has a U-shaped cross-section, with its opening facing the platform's transverse beam on the other side. The cross-section of the platform support is smaller than that of the base support. Each platform support has an end plate 9 at its bottom, extending downwards into the base support. Locking holes are located on the two side wing plates of the platform supports.

[0031] The lifting screw is installed in the base support column. The bottom end of the lifting screw is fixed to the base via a foot cup 10, and the top end of the lifting screw passes upward through the end plate and extends into the platform support column. The lifting nut is located below the end plate and engages with the lifting screw. The locking bolt passes through the locking groove and locking hole before the locking nut is tightened.

[0032] The platform crossbeam and platform longitudinal beam are provided with connecting holes 2.4. The floor shelf is provided with mating holes 11.1 corresponding to the connecting holes. Floor shelves can be installed on all four sides of the platform. The floor shelves are horizontally fixed to the sides of the platform crossbeam and platform longitudinal beam by fasteners installed in the connecting holes and mating holes to facilitate the laying of the anti-static floor. The cross-section of the floor shelf is L-shaped. The floor shelf is the same length as the platform crossbeam and is fixed to the platform crossbeam, or the floor shelf is the same length as the platform longitudinal beam and is fixed to the platform longitudinal beam.

[0033] The platforms of two adjacent adjustable bases can also be fixed in pairs by fasteners installed in the connection holes.

[0034] To ensure structural strength and durability, the lifting screw is made of high-strength alloy steel and chrome-plated to significantly improve wear resistance and corrosion resistance. The support feet are made of engineering plastic with anti-slip grooves on the bottom to enhance friction between the base and the ground. All components of the platform and base are made by bending cold-rolled steel sheets. welding Molding. The base supports and platform supports are also made of cold-rolled steel plate with bending. The platform has pre-drilled mounting holes for connection with standard cabinets, and the dimensions are strictly determined according to the installation dimensions of standard cabinets to ensure precise fit with the cabinets.

[0035] The installation process of this utility model is as follows: 1. Use expansion bolts to fix the base to the ground foundation. Adjust the height of the platform from the ground by using the lifting nut. After the height is adjusted to the preset position, install the locking bolts and locking nuts to lock the platform support to prevent height deviation during use. The maximum adjustment range of the platform height is ±50mm.

[0036] 2. To meet the electrostatic protection requirements of the computer room, the communication computer room needs to be equipped with an electrostatic floor. Use fasteners to fix the floor supports to the side of the platform facing the location where the electrostatic floor will be laid, and place the edges of the electrostatic floor on the floor supports.

[0037] 3. When the cabinets need to be installed side by side, the network cabinets are arranged side by side using adjustable bases, and the platforms are fixed in pairs with fasteners to effectively ensure the overall structural consistency and stability after the cabinets are installed side by side.

[0038] This utility model features a reasonable design, convenient adjustment, and strong stability, which improves the flexibility and construction efficiency of cabinet installation. While enabling convenient manual adjustment, it ensures that the base has sufficient load-bearing capacity, structural stability, and installation adaptability to meet the diverse usage needs in different installation environments.
