Description

Technical Field

[0001] The utility model relates to a network cabinet, in particular to a network cabinet with an integral top and bottom frame. Background Technique

[0002] The top frame and the bottom frame of traditional network cabinets generally adopt a split design. As Figure 17 and Figure 18 shown, both its top frame and bottom frame include four cross beams. Each cross beam is spliced by an upper component 8.1 and a lower component 8.2. A connecting piece 7 is added between adjacent cross beams and fixed to the column 2 by means of bolt connection or welding to form a frame. Then, a plate is installed in the middle of the frame as the top surface or the bottom surface. This split design has the following series of problems:

[0003] 1. Poor structural strength: When the split frame bears a large weight or is in a vibrating environment, it is prone to deformation, which will further affect the overall stability of the cabinet.

[0004] 2. Complicated installation process: It is necessary to separately assemble the top frame, the bottom frame and the column. The process is complex, resulting in high costs.

[0005] 3. Low heat dissipation efficiency: Due to the existence of many gaps in the split structure (such as between the top surface and the cross beam, between the bottom surface and the cross beam, between the upper component and the lower component), air flow short circuit is likely to occur during the heat dissipation process, resulting in uneven heat dissipation inside the cabinet.

[0006] Therefore, there is an urgent need in the market for a network cabinet with a more optimized structure and more comprehensive performance to meet the growing usage requirements. Content of the Utility Model

[0007] The purpose of the utility model is to overcome the deficiencies in the above background technique and provide a network cabinet with an integral top and bottom frame, which should have the advantages of reliable structure, convenient assembly and high heat dissipation efficiency.

[0008] The technical solution of the utility model is:

[0009] A network cabinet with an integral top and bottom frame includes frame plates serving as the top surface and the bottom surface of the network cabinet and columns vertically fixed between the upper and lower frame plates; flanges are formed by bending around the frame plates; the flanges are hollow and stepped and extend outwards; the columns are profiles.

[0010] The frame plates are arranged symmetrically up and down; the flange includes a first vertical edge, a first horizontal edge, a second vertical edge, a second horizontal edge and a third vertical edge connected in sequence.

[0011] The adjacent retaining edges of the flanging are bent at 90 degrees and transition arc-shaped; the first horizontal retaining edge, the second vertical retaining edge and the second horizontal retaining edge form a convex edge extending outward.

[0012] Both ends of the flanging cover the upper and lower end faces of the column.

[0013] Both ends of the first horizontal retaining edge are provided with baffles, and the shape of the baffles is suitable for half of the shape of the end face of the column.

[0014] Connectors are fixed at both ends of the column; the frame plate is fixed to the connectors at both ends of the column through fasteners.

[0015] Mounting holes for installing fasteners are provided at the four corners of the frame plate.

[0016] The column is a 16-fold profile.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. The top and bottom of the present utility model adopt an integral structure, making the overall structure of the cabinet more compact, improving the structural strength and assembly efficiency, and being more suitable for mass production in factories.

[0019] 2. Both the top and bottom of the present utility model adopt continuously bent flangings, which further improve the structural strength while reducing the product weight, and also facilitate modular assembly.

[0020] 3. The present utility model greatly reduces the number of gaps, is not prone to cause air flow short circuit, and thus improves the heat dissipation efficiency. Description of the Drawings

Detailed implementation manners

[0041] In order to make the purpose, technical solutions and advantages of the present 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 only used to explain the present utility model and are not used to limit the present utility model.

[0042] As Figure 1As shown in the figure, an integrated top and bottom frame network cabinet includes a frame plate 1, columns 2, a front door 3, a rear door 4, and side plates 5. Two frame plates are arranged horizontally up and down. Four columns are vertically fixed between the upper and lower frame plates. The front door, rear door, and side plates are installed on the sides of the columns. The columns are also connected by a support member 6.

[0043] The frame plate is integrally formed by continuous bending. Four flanges 1-1 are formed by bending the four peripheral edges of the frame plate. As Figure 11 shown, the flange is a stepped shape extending outward and the cross-section of the flange is a hollow structure. The flange includes a first vertical stop edge 1.1, a first horizontal stop edge 1.2, a second vertical stop edge 1.3, a second horizontal stop edge 1.4, and a third vertical stop edge 1.5 connected in sequence. The first horizontal stop edge, the second vertical stop edge, and the second horizontal stop edge form a convex edge extending outward. The adjacent stop edges are bent at 90 degrees and have an arc transition.

[0044] The two frame plates are symmetrically arranged up and down. The upper frame plate serves as the top surface of the network cabinet. The four flanges of the upper frame plate are located at the four peripheral edges of the bottom surface of the frame plate. The lower frame plate serves as the bottom surface of the network cabinet. The four flanges of the lower frame plate are located at the four peripheral edges of the top surface of the frame plate.

[0045] For the upper frame plate ( Figure 11 ), the first vertical stop edge is bent downward at 90 degrees from the four peripheral edges of the frame plate. The first horizontal stop edge is bent outward (to the left in the figure) at 90 degrees from the bottom edge of the first vertical stop edge. The second vertical stop edge is bent downward at 90 degrees from the outer edge of the first horizontal stop edge. The second horizontal stop edge is bent inward (to the right in the figure) at 90 degrees from the bottom edge of the second vertical stop edge. The third vertical stop edge is bent upward at 90 degrees from the inner edge of the second horizontal stop edge.

[0046] For the lower frame plate (omitted in the figure), the first vertical stop edge is bent upward at 90 degrees from the four peripheral edges of the frame plate. The first horizontal stop edge is bent outward at 90 degrees from the top edge of the first vertical stop edge. The second vertical stop edge is bent upward at 90 degrees from the outer edge of the first horizontal stop edge. The second horizontal stop edge is bent inward at 90 degrees from the top edge of the second vertical stop edge. The third vertical stop edge is bent downward at 90 degrees from the inner edge of the second horizontal stop edge.

[0047] In the frame plate, the width of the first horizontal stop edge is less than the width of the second horizontal stop edge ( Figure 11 the horizontal distance), and the height of the second vertical stop edge is equal to the height of the third vertical stop edge ( Figure 11 the vertical distance).

[0048] The stepped hollow flanging replaces the traditional splicing method of the upper component, the lower component and the plate, which not only ensures the strength of the cabinet, but also facilitates the production device, reduces the number of gaps, and improves the heat dissipation efficiency.

[0049] The column is a 16-fold profile. The frame plate and the column are fixed by fasteners and a connector 7.

[0050] As Figure 12 shown, the connector is fixed at both ends of the column. As Figure 13 shown, the connector is welded and fixed to the inner side of the column. As Figure 15 shown, the side of the connector is provided with a notch 7.2 for positioning, and the top end of the connector is provided with a screw hole 7.1.

[0051] The frame plate is fixed to the connectors at both ends of the column by fasteners. The four corners of the frame plate are provided with mounting holes 1.6 for mounting fasteners. After the fasteners (bolts) pass through the mounting holes, they are engaged with the screw holes of the connectors, so as to press and fix the frame plate at both ends of the column.

[0052] Both ends of the flanging cover the upper and lower end faces of the column. As Figure 14 shown, both ends of the first horizontal baffle are provided with baffles 1.21, and the shape of the baffle is suitable for half of the shape of the column end face, that is, the baffle on the left flanging covers the left half of the column end face, and the baffle on the right flanging covers the right half of the column end face. The edge of the baffle is serrated, and the serration is suitable for the outer contour shape of the column to ensure that the baffle can just cover the column end face and will not protrude from the side of the column.

[0053] The top surface and the bottom surface of the present utility model adopt an integral design, that is, the frame plates at the top and bottom of the cabinet are integrally formed by continuous bending of the same metal plate, which significantly improves the compressive and torsional resistance performance; at the same time, the structure of the integral design is more compact, saving at least 10% of the processing time (eliminating the assembly time of the original split top and bottom plates), improving the processing efficiency, and being more suitable for mass production in factories; in addition, the 16-fold profile further increases the overall strength. In the existing solutions, some cabinets use profiles with fewer bending times, generally 8-12 folds, which results in a lower section moment of inertia and insufficient torsional resistance performance.

[0054] The preferred embodiments of the present utility model are given in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present utility model more thorough and comprehensive.
