[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] A symmetrical structural profile of a control cabinet, such as Figures 1 to 3 As shown, the profile body 1 includes a profile body 1 and a mounting hole provided on the profile body 1; the cross section of the profile body 1 is a hexagonal structure, and the hexagonal structure includes a first connection portion 8, a second connection portion 9, a third connection portion 10, a fourth connection portion 11, a fifth connection portion 12, a sixth connection portion 13 and a seventh connection portion 14. Specifically, the profile body 1 can be formed by rolling a whole steel plate at one time, and the inner and outer sides of the profile body 1 are overlapped to form, and the shape of the hexagonal structure ensures the tensile (compressive) and torsional strength of the profile body 1, which is conducive to improving the overall structural strength and reliability of the profile.

[0033] The above-mentioned first connecting part 8 is arranged flush with the seventh connecting part 14, and both the first connecting part 8 and the seventh connecting part 14 are provided with reinforcing ribs 2, the length direction of the reinforcing ribs 2 is the same as the length direction of the profile body 1, and the reinforcing ribs 2 are provided with positioning grooves 3, and multiple positioning grooves 3 are arranged at intervals along the length direction of the reinforcing ribs 2.

[0034] Exemplarily, the reinforcing rib 2 is integrally formed with the first connecting portion 8 or the seventh connecting portion 14. By arranging the reinforcing rib 2 on the first connecting portion 8 and the seventh connecting portion 14, not only the structural strength and rigidity of the profile body 1 are increased, but also the positioning groove 3 on the reinforcing rib 2 can also play a good limiting role for the panel. After the cabinet frame is assembled, the fixed limitation of the peripheral panel can be achieved through the positioning groove 3, which improves the stability of the peripheral panel and reduces the difficulty of installing and fixing the peripheral panel.

[0035] One end of the second connection portion 9 is connected to the first connection portion 8 , and the other end is connected to the third connection portion 10 .

[0036] One end of the fourth connection part 11 is connected to the third connection part 10, and the other end is connected to the fifth connection part 12. The fourth connection part 11 is arranged in parallel with the first connection part 8 or the seventh connection part 14, and the length of the fourth connection part 11 is less than the sum of the lengths of the first connection part 8 and the seventh connection part 14; the third connection part 10, the fifth connection part 12, and the fourth connection part 11 are each provided with a group of mounting holes, and the group of mounting holes includes a plurality of mounting holes arranged at intervals along the length direction of the profile body 1.

[0037] One end of the sixth connection portion 13 is connected to the fifth connection portion 12 , and the other end is connected to the seventh connection portion 14 .

[0038] Optionally, a bending portion 5 for enhancing structural strength is provided at a position different from the mounting hole on the third connecting portion 10 and the fifth connecting portion 12 , and the length direction of the bending portion 5 is the same as the length direction of the profile body 1 .

[0039] For example, the cross section of the bending portion 5 is a wave-shaped or W-shaped structure. The bending portion 5 can not only further improve the deformation resistance of the profile body 1, but also serve as a limiting structure for the inner mounting plate or mounting beam, further improving the applicability of the profile body 1 in actual use.

[0040] Optionally, there is a deformation gap between the first connection part 8 and the seventh connection part 14. By using a whole piece of steel plate for one-time roll forming, a certain deformation gap, for example, 1-3 mm, can be reserved between the first connection part 8 and the seventh connection part 14 after forming to meet the deformation requirements of the profile due to thermal expansion and contraction, which is beneficial to improving the practicality of the profile in different temperature environments and is beneficial to extending the service life of the profile.

[0041] Optionally, the first connection portion 8 and the seventh connection portion 14 have the same length. Exemplarily, the reinforcing ribs 2 on the first connection portion 8 and the seventh connection portion 14 are both arranged toward the deformation gap, and by arranging the first connection portion 8 and the seventh connection portion 14 to have the same length, a stable symmetrical structure can be formed, which is beneficial to ensuring the stability of the structure of the profile body 1, and is also convenient for installing the profile body 1 or assembling a panel on the profile body 1.

[0042] Optionally, the first connecting portion 8 and the seventh connecting portion 14 are provided with an assembly hole 4 at a position corresponding to the positioning groove 3, and the assembly hole 4 is connected to the positioning groove 3. Exemplarily, the assembly hole 4 can be used to assemble such a profile or install a peripheral plate on such a profile. By setting the assembly hole 4 corresponding to the positioning groove 3, it is possible to avoid damaging the overall structure of the reinforcing rib 2, thereby ensuring the reinforcing effect of the reinforcing rib 2 on the structural strength of the profile body 1.

[0043] Optionally, the second connection portion 9 is arranged in parallel with the fifth connection portion 12, and the third connection portion 10 is arranged in parallel with the sixth connection portion 13. By arranging the second connection portion 9 and the fifth connection portion 12 in parallel, a stable symmetrical structure can be formed.

[0044] Specifically, the angle between the first connection part 8 and the second connection part 9, the angle between the third connection part 10 and the fourth connection part 11, the angle between the fourth connection part 11 and the fifth connection part 12, and the angle between the sixth connection part 13 and the seventh connection part 14 are all obtuse angles; the angle between the second connection part 9 and the third connection part 10, and the angle between the fifth connection part 12 and the sixth connection part 13 are all right angles or acute angles. By adopting the above structural arrangement, it is beneficial to further improve the structural strength and stability of the entire profile.

[0045] Optionally, the mounting holes include circular holes 7 and rectangular holes 6, and the circular holes 7 and rectangular holes 6 are alternately arranged along the length direction of the profile body 1. Specifically, the spacing between the circular holes 7 and the rectangular holes 6 is 25 mm. By alternately arranging the circular holes 7 and the rectangular holes 6, the profile can be used to install different equipment, which is conducive to improving the applicability and versatility of the profile in actual use.

[0046] The utility model provides a symmetrical structural profile for a control cabinet, which has the advantages of low material cost, convenient processing, high strength, stable performance, and high protection level. The single cabinet frame and the cabinet frame connection can be freely assembled and combined, so that the control cabinet processed by this reinforced profile can be used in a variety of electrical fields, which is convenient for the multi-dimensional free fixation of peripheral panels. The profile body is formed by rolling a whole piece of steel plate at one time, and the inner and outer sides of the profile are overlapped and formed, and reinforcing ribs and bending parts are added on the inner and outer sides. Not only can the structural strength of the profile be effectively increased, but it is also conducive to the subsequent installation of peripheral panels, ensuring that after the peripheral panels are installed, this profile still has good reliability and service life.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
