Description

TECHNICAL FIELD

[0001] The present application relates to the field of electrical cabinets, in particular to a welding-free high-tightening thickened electrical cabinet framework using splicing pieces for electrical cabinets. BACKGROUND

[0002] As a cabinet for containing electronic components, electrical cabinets are widely used in the power grid field. During assembly, a strong framework is often needed as a support structure. At present, most electrical cabinet frameworks are connected by welding. The welded framework has the advantages of high strength and is not easy to deform. However, the connection between the framework supports cannot be adjusted after welding. Moreover, the welded contact points are easily eroded after long-term exposure to air, leading to poor welding. Therefore, welding-free frameworks have appeared on the market, such as CN210897984U (Utility Model: A fully spliced switch cabinet framework), CN213636620U (Utility Model: A welding-free and flexible splicing power cabinet), and CN104466709B (Invention: A 45-degree wing angle G-profile switch cabinet body).

[0003] CN210897984U (Utility Model: A fully spliced switch cabinet framework) discloses a fully spliced switch cabinet framework. The key connection mechanism of this utility model is to set a side screw hole at the connection position and connect the relevant screw holes with a connecting piece to form an overall framework. Although this framework can be basically combined into a framework structure without welding, the cross beams, longitudinal beams, and columns in the framework are relatively thin, and the overall rigidity, especially at each fixed connection point, is insufficient. When a large electrical cabinet is needed, the overall structure is prone to collapse, and the adaptability is insufficient.

[0004] CN213636620U (Utility Model: A welding-free and flexible splicing power cabinet) discloses a welding-free and flexible splicing power cabinet. According to the specification and drawings, the cabinet uses an angle code to connect and lock a 90-degree right angle at the fixed corner end point. The structure is simple. However, the connection of the angle code cannot directly reinforce the corner end point, and the structure is relatively loose.

[0005] CN104466709B (Invention Patent: A 45-degree wing angle G-profile switch cabinet body) discloses a 45-degree wing angle G-profile switch cabinet body. The cabinet body end points are spliced into a configuration through a certain configuration, and the end of the frame is fixed by a sheet metal tee joint. However, the fixation in this structure is fixed by a press-in counterbore, without any reinforcement measures for the end points. Although it overcomes certain support strength problems, the installation is complex, and it is difficult to disassemble after installation, affecting the later maintenance. SUMMARY

[0028] The concept, specific structure and generated technical effects of the present application will be clearly and completely described below in combination with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application. Each technical feature in the present application can be combined with each other without conflict.

[0029] As shown in Figure 1 , an electric cabinet splicing piece, comprising a first L-shaped panel 11 and a second L-shaped panel 12, the first L-shaped panel 11 and the second L-shaped panel 12 are integrally connected and thereby constitute a beam connecting panel 111, a vertical beam connecting panel 112, a first vertical column connecting panel 113 and a second vertical column connecting panel 115; the beam connecting panel 111, the vertical beam connecting panel 112, the first vertical column connecting panel 113 and the second vertical column connecting panel 115 are all provided with fastening holes 114 for fastening components. Compared with the prior art, the unique structure of the electric cabinet splicing piece used in the present embodiment is a three-dimensional splicing piece, which splits the splicing direction into X, Y and Z axial splicing, each direction is provided with a hole for connection, and each axis is connected to at least two components of the beam, the vertical beam and the vertical column, and even three components in some axes, thereby the unique structure of the beam, the vertical beam and the vertical column can be fastened, and the overall fastening degree is improved.

[0030] As shown in Figures 2-6 , a welding-free high-fastening thickened electric cabinet framework using the electric cabinet splicing piece of the above-mentioned embodiment 1, which is surrounded by a plurality of vertical column assemblies 2, a plurality of beam assemblies 3 and a plurality of vertical beam assemblies 4, and connected by the electric cabinet splicing piece.

[0031] The vertical column assembly 2 is a hollow assembly, which is provided with an inner hole 21 for embedding the vertical beam fastening column 43 of the vertical beam assembly 4; it needs to be particularly pointed out that, in order to strengthen the firmness of the inner hole, the inner hole is generally formed by bending process and constitutes a firm structure, and the vertical beam fastening column also constitutes the structure; the square structure is used in the present embodiment, and the stability will be further improved.

[0032] The longitudinal beam assembly 4 comprises a longitudinal beam plate 41, a reinforcing beam 42 and two longitudinal beam fastening columns 43. The longitudinal beam plate 41 and the reinforcing beam 42 are fixedly connected, and the two longitudinal beam fastening columns 43 are fixedly arranged at the two ends of the longitudinal beam plate 41 respectively. The longitudinal beam fastening column 43 is provided with a plurality of screw holes for fixation.

[0033] The cross beam assembly 3 comprises a cross beam main body 31, a first cross beam reinforcing plate 32 and a second cross beam reinforcing plate 33. The cross beam main body 31, the first cross beam reinforcing plate 32 and the second cross beam reinforcing plate 33 are connected perpendicularly to each other and form a hollow "L" type structure. The first cross beam reinforcing plate 32 and the second cross beam reinforcing plate 33 are provided with a plurality of screw holes for fixation.

[0034] The above embodiments are the basic configurations of the column assembly 2, the cross beam assembly 3 and the longitudinal beam assembly 4 respectively. It needs to be clarified that the first cross beam reinforcing plate 32 and the second cross beam reinforcing plate 33 in the cross beam assembly 3 are connected perpendicularly to each other and form a hollow "L" type structure which is matched with the first L type panel 11. Thus, the first L type panel 11 can be embedded into the hollow "L" type structure, and the three components are connected by the fastening assembly.

[0035] It needs to be clarified that, as shown in the figure, when the longitudinal beam assembly 4 is inserted into the column assembly 2, the screw holes of the longitudinal beam assembly 4, the screw holes of the column assembly 2 and the screw holes of the side of the cross beam assembly 3 have a corresponding relationship. Thus, the fastening assembly can be embedded into the inside of the cross beam assembly 3, and the above three assemblies can be penetrated from the side and form a fixed connection. The specific connection mode is as follows: the splicing piece for electric cabinet is arranged at the inner end of the hollow "L" type structure of the cross beam assembly 3; the longitudinal beam fastening column 43 is embedded into the inner hole 21; the first column connecting panel 113, the inner end of the cross beam assembly 3, the end of the column assembly 2 and the longitudinal beam fastening column 43 are fixed by the fastening assembly; the second column connecting panel 115, the inner end of the cross beam assembly 3 and the end of the column assembly 2 (marked as the X axis direction) are fixed by the fastening assembly.

[0036] On the basis of the above connection mode, in order to strengthen the fastening degree, the three-dimensional form of the splicing piece is used. After the X axis connection, the splicing piece is used to fasten and connect the side of the column and the second cross beam reinforcing plate 33 (marked as the Y axis direction). The above connection is realized by the "L" type characteristics of the cross beam connecting panel 111 and the second column connecting panel 115. The fastening of the column assembly 2 and the longitudinal beam fastening column 43 in the Y axis direction on the cross beam connecting panel 111 is realized at the same time. The fastening connection of the second cross beam reinforcing plate 33 and the second column connecting panel 115 is also realized. At the same time when the fastening of the column assembly 2 and the longitudinal beam fastening column 43 in the X and Y axis directions is ensured, the second cross beam reinforcing plate 33 located on the Z axis is also added to the fastening, which further strengthens the stability.

[0037] Further, in the Z-axis, since the longitudinal beam connecting panel 112 and the first vertical column connecting panel 113 are embedded into the cross beam assembly 3 as a whole, and since the first vertical column connecting panel 113 and the longitudinal beam connecting panel 112 are in the same plane, the fastening in the Z-axis can be performed in the same way as the fastening in the X-axis.

[0038] It is also necessary to mention again that the screw hole positions on the vertical column assembly are staggered, and generally two screw holes are provided on each connecting panel to match the relevant assembly.

[0039] As one of the embodiments, the above-mentioned fastening assembly is a fastening screw. In the overall framework, generally a square framework is formed by four vertical column assemblies 2, four cross beam assemblies 3 and four longitudinal beam assemblies 4, the above-mentioned electrical cabinet connecting piece is used for the splicing at each end point, and the splicing is performed according to the above-mentioned splicing mode. The cumulative cabinet framework is spliced at eight positions, and the four vertical column assemblies 2 are divided into two groups, and the middle part is fixedly connected with the closing panel 5.

[0040] The preferred embodiments of the present application are described above, but the present application is not limited to the above-mentioned embodiments. Those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
