[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] In existing technology, server racks are mainly fixed to the ground with bolts. To ensure that the server rack is installed on the ground, an insulating mat is installed between the server rack and the ground. The insulating mat insulates and isolates the server rack from the ground. Mounting holes are opened at the bottom of both the insulating mat and the server rack frame. Insulating blocks are placed in the mounting holes. Bolts pass through the insulating blocks and are fixed to the ground. The insulating blocks insulate and isolate the bolts from the server rack.

[0022] Since the insulating block is inserted into the mounting hole, if the insulating block cannot completely fill the mounting hole, or if the insulating block is broken or cracked, resulting in a reduction in insulation performance, then there will be creepage at the mounting hole, leading to poor overall insulation reliability of the cabinet.

[0023] To resolve the aforementioned technical issues, please refer to the following: Figures 1 to 4 The floating rack mounting structure provided by this utility model will now be described. The floating rack mounting structure includes a frame 1, an insulating mat 2, an insulating sealing washer 3, a first insulating structure 4, and a first fastener 5. The frame 1 has a first mounting hole 111; the insulating mat 2 is placed on the ground and has a second mounting hole 21; the frame 1 is placed on the insulating mat 2, the first mounting hole 111 and the second mounting hole 21 are axially aligned, and the diameter of the first mounting hole 111 is larger than the diameter of the second mounting hole 21; the insulating sealing washer 3 is placed on the top surface of the insulating mat 2 and is located within the first mounting hole 111; the first insulating structure 4 is partially embedded in the first mounting hole 111 and abuts against the insulating sealing washer 3, and partially extends out of the first mounting hole 111; the first insulating structure 4 has a third mounting hole 44; one end of the first fastener 5 passes through the third mounting hole 44 and is fixed to the ground.

[0024] Frame 1 is the main supporting structure of the cabinet. All electrical components or electrical modules inside the cabinet are fixed to frame 1. All side panels of the cabinet are also fixed to frame 1. Therefore, frame 1 needs to have sufficient strength and is generally made of steel.

[0025] An insulating mat 2 is laid on the ground to insulate the frame 1 from the ground. The second mounting hole 21 on the insulating mat 2 is axially aligned with the first mounting hole 111. For ease of processing, the second mounting hole 21 and the first mounting hole 111 are preferably round holes.

[0026] The first insulating structure 4 is embedded in the first mounting hole 111, and the first fastener 5 passes through the first insulating structure 4 to fix the frame 1 to the ground. The first insulating structure 4 provides insulation and isolation between the first fastener 5 and the frame 1. Preferably, the first fastener 5 is a bolt, and a leveling washer 6 is also fitted on the bolt of the first fastener 5. The leveling washer 6 abuts against the nut portion of the first fastener 5 and the protruding end face of the first insulating structure 4. The third mounting hole 44 is a round hole.

[0027] The insulating sealing gasket 3 is located inside the first mounting hole 111 and axially abuts against the first insulating structure 4, serving as a radial insulating barrier between the first mounting hole 111 and the second mounting hole 21. In other words, it serves as a radial insulating barrier between the ground and the frame 1, thereby preventing the cabinet from directly creeping to the ground through the first mounting hole 111 and the second mounting hole 21.

[0028] Since the insulating sealing gasket 3 provides radial insulation, the first insulating structure 4 does not need to completely fill the first mounting hole 111, thereby reducing the assembly accuracy of the first insulating structure 4 and the first mounting hole 111 and simplifying the design requirements of the first insulating structure 4.

[0029] Moreover, even if excessive force is applied when tightening the first fastener, causing cracks in the first insulating structure 4, or if cracks appear in the first insulating structure 4 after prolonged use, resulting in a reduction in its own insulation performance, the first insulating structure 4 and the insulating sealing gasket 3 are axially abutting each other, thus preventing creepage through the first mounting hole 111.

[0030] It should be noted that a plurality of first mounting holes 111 are provided on the frame 1, and a plurality of second mounting holes 21 are provided on the insulating mat 2. The aforementioned insulating sealing gaskets 3 and first insulating structures 4 are evenly distributed in each first mounting hole 111, and each first insulating structure 4 is provided with a first fastener 5.

[0031] Compared with the prior art, the floating mounting structure of the cabinet provided by this utility model makes the diameter of the first mounting hole 111 of the frame 1 larger than the diameter of the second mounting hole 21 of the insulating mat 2, and adds an insulating sealing gasket 3 inside the first mounting hole 111. The insulating sealing gasket 3 abuts axially with the first insulating structure 4. The insulating sealing gasket 3 plays the role of radially isolating the first mounting hole 111 and the second mounting hole 21, preventing the cabinet from creeping electricity to the ground from the second mounting hole 21, and ensuring that the cabinet has good insulation stability performance.

[0032] In some embodiments, the first insulating structure 4 described above can be as follows: Figure 4 and Figure 5 The structure shown is described in the following document. Figure 4 and Figure 5The first insulating structure 4 includes a first frustum 41 and a second frustum 42. The first frustum 41 is embedded in the first mounting hole 111, and its axial end face abuts against the insulating sealing gasket 3; the second frustum 42 is connected to the first frustum 41 and extends out of the first mounting hole 111; the outer peripheral surface of the second frustum 42 protrudes radially outward relative to the outer peripheral surface of the first frustum 41; the axial end face of the second frustum 42 abuts against the frame 1.

[0033] The outer diameter of the first frustum 41 can be slightly smaller than the inner diameter of the first mounting hole 111, so as to facilitate the insertion of the first frustum 41 into the first mounting hole 111. Since the insulating sealing gasket 3 is placed in the first mounting hole 111, the axial length of the first frustum 41 can also be slightly smaller than the axial depth of the first mounting hole 111, so as to reduce the assembly accuracy of the first frustum 41 and the first mounting hole 111.

[0034] The outer diameter of the second frustum 42 is larger than that of the first frustum 41, and the second frustum 42 and the first frustum 41 form a cylindrical stepped structure. Since the first fastener 5 needs to be inserted inside the first insulating structure 4, designing the first insulating structure 4 as a cylindrical stepped structure can improve its own strength.

[0035] Preferably, the axial length of the second frustum 42 is greater than the axial length of the first frustum 41, and is at least three times the axial length of the first frustum 41. The second frustum 42 can better distribute the stress generated when the first fastener 5 is tightened, preventing the first insulating structure 4 from cracking and failing.

[0036] In some embodiments, the first insulating structure 4 described above may also employ, for example... Figure 4 and Figure 5 The structure shown is described in the following document. Figure 4 and Figure 5 The first insulating structure 4 also includes a third frustum 43, which is connected to the first frustum 41 and extends into the second mounting hole 21.

[0037] The second frustum 42, the first frustum 41, and the third frustum 43 are connected axially in sequence, with their outer diameters decreasing sequentially. The third frustum 43 extends into the second mounting hole 21 to increase the axial length of the first insulating structure 4, thereby enhancing its strength and further preventing the first insulating structure 4 from cracking.

[0038] It should be noted that the outer diameter of the third frustum 43 can be slightly smaller than the inner diameter of the second mounting hole 21. The third frustum 43 does not need to be fitted into the second mounting hole 21, but only needs to be inserted into the second mounting hole 21. This can reduce the assembly difficulty of the first insulating structure 4.

[0039] In some embodiments, the insulating sealing gasket 3 is made of rubber. Rubber is elastic and can be compressed and deformed. After assembling the floating mounting structure, the tighter the first fastener 5 is tightened, the more tightly the first insulating structure 4 contacts the insulating sealing gasket 3, and the better the insulation performance.

[0040] In addition, since the insulating sealing gasket 3 can be deformed by compression, when designing the first insulating structure 4, it is not necessary to make the sum of the axial lengths of the first frustum 41 and the insulating sealing gasket 3 exactly equal to the depth of the first mounting hole 111, which further reduces the design precision of the first insulating structure 4 and simplifies the manufacturing process.

[0041] Furthermore, the rubber material has good anti-aging properties, which can further increase the reliability and stability of the floating installation structure of the cabinet.

[0042] In some embodiments, the insulating mat 2 described above may be as follows: Figure 1 The structure shown is described in the following document. Figure 1 The outer periphery of the insulating mat 2 extends outward relative to the outer periphery of the frame 1.

[0043] The insulating mat 2 is made of PC (Polycarbonate) material, which has good mechanical and insulating properties. The outer periphery of the insulating mat 2 extends outward relative to the outer periphery of the frame 1 to prevent the cabinet from directly creeping to the ground.

[0044] In some embodiments, the above-described floating mounting structure further includes a vertical beam 7 and a second insulating structure 8. The vertical beam 7 is used to assemble and fix the electrical module; the second insulating structure 8 is connected between the end of the vertical beam 7 and the frame 1, and is used to insulate and isolate the vertical beam 7 from the frame 1.

[0045] Since the vertical beam 7 is to fix the electrical module, it is preferably a steel beam to ensure its fixing strength. Therefore, there is an electrical connection between the electrical module and the vertical beam 7. In order to ensure that the electrical module is insulated from the frame 1, a second insulation structure 8 is set at the upper and lower ends of the vertical beam 7 respectively. The vertical beam 7 is fixed to the frame 1 through the second insulation structure 8.

[0046] The second insulation structure 8 is used to insulate and isolate the electrical module from the frame 1, ensuring that the frame 1 is not energized.

[0047] It should be noted that the frame 1 is provided with multiple vertical beams 7, and each vertical beam 7 has a second connecting structure at both ends, such as... Figure 1 As shown.

[0048] In some embodiments, the second insulating structure 8 described above may employ, for example... Figure 6 and Figure 7 The structure shown is described in the following document. Figure 6 and Figure 7The outer periphery of the second insulating structure 8 protrudes outward relative to the outer periphery of the vertical beam 7, and the protruding part of the second insulating structure 8 is connected to the frame 1 by a second fastener 91; the second insulating structure 8 is also provided with an insert groove 811, and a third fastener 92 is provided in the insert groove 811, and the third fastener 92 is connected to the vertical beam 7.

[0049] The second fastener 91 is fixed to the protruding part of the second insulating structure 8, and the third fastener 92 is fixed to the corresponding parts of the second insulating structure 8 and the vertical beam 7. The second fastener 91 and the third fastener 92 are preferably bolts. The threaded part of the second fastener 91 passes through the second insulating structure 8 and the frame 1 in sequence and is fastened with a nut. The nut of the third fastener 92 is located in the mounting groove 811, the threaded part passes through the vertical beam 7, and is fastened with a nut.

[0050] The second fastener 91 and the third fastener 92 are set separately and there is no connection between them, so as to ensure that the vertical beam 7 and the frame 1 are completely insulated and isolated.

[0051] Please see Figure 6 and Figure 7 Based on the above embodiments, the second insulating structure 8 includes a first insulating pad 81 and a second insulating pad 82; the first insulating pad 81 is fixedly mounted on the frame 1; the first insulating pad 81 is provided with the above-mentioned mounting groove 811, and the groove opening of the mounting groove 811 faces the vertical beam 7; the second insulating pad 82 is placed on the first insulating pad 81 and abuts against the end of the vertical beam 7.

[0052] The frame 1, the first insulating pad 81, and the second insulating pad 82 are connected by a second fastener 91; one end of the third fastener 92 passes through the end of the second insulating pad 82 and the end of the vertical beam 7 in sequence, and the first insulating pad 81 and the vertical beam 7 are connected by the third fastener 92.

[0053] The second insulating structure 8 is divided into a first insulating pad 81 and a second insulating pad 82, which can improve the insulation performance of the second insulating structure 8.

[0054] The mounting groove 811 is formed on the first insulating pad 81, and there is also a second insulating pad 82 between the first insulating pad 81 and the vertical beam 7. The second insulating pad 82 serves to limit the upper and lower positions of the third fastener 92. Therefore, the nut part of the third fastener 92 does not need to be completely identical to the structure of the mounting groove 811. The nut part of the third fastener 92 only needs to be placed in the mounting groove 811. The two do not need to be interference-fitted, thereby simplifying the design precision of the mounting groove 811 and making the second insulating structure 8 easier to process and manufacture.

[0055] In some embodiments, the framework 1 described above may adopt the following approach: Figure 1 The structure shown is described in the following document. Figure 1The frame 1 includes a supporting bottom beam 11 and a main frame 12; the supporting bottom beam 11 is placed on an insulating mat 2; the bottom surface of the supporting bottom beam 11 is provided with a first insulating structure 4; the main frame 12 is placed on the supporting bottom beam 11; and a second insulating structure 8 is provided on the main frame 12.

[0056] Multiple parallel and spaced support beams 11 support the main frame 12 and elevate it. Each support beam 11 has a first mounting hole 111 at both ends of its length. This means that each support beam 11 is insulated and fixed to the ground at both ends by a first insulating structure 4, an insulating sealing washer 3, and a first fastener 5. The support beam 11 is a C-shaped beam, and the first fastener 5 and the first insulating structure 4 are hidden within the inner cavity of the C-shaped beam.

[0057] The main frame 12 is a hexagonal frame structure, composed of multiple horizontal beams, multiple vertical beams, and multiple vertical beams. Vertical beams 7 are positioned between corresponding upper and lower vertical beams. The main frame 12 is used to assemble the cabinet side panels.

[0058] Based on the same inventive concept, this application also provides a cabinet, including the above-described cabinet floating installation structure.

[0059] The cabinet provided by this utility model, due to the adoption of the above-mentioned floating installation structure, can eliminate creepage and improve the insulation stability of the cabinet.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
