Abstract
Description
Technical Field
[0001] This utility model relates to the field of cabinet profiles, and specifically to a cabinet profile structure. Background Technology
[0002] Nine-fold profile cabinets are widely used in electronic equipment storage, industrial control, and other fields due to their excellent strength and stability. Traditional nine-fold profile cabinets typically use a frame structure formed by combining several sets of profiles to meet equipment installation and protection requirements.
[0003] However, in the early stages of laser welding technology development, profiles were mostly fixed using a "dead edge" structure (such as...). Figure 3 As shown in the diagram, the upper end of the first horizontal segment extends to the space between the upper end of the first U-shaped fold and the second vertical segment, resulting in a three-layer stacked structure at the top of the profile. Although it can be fixed by physical wrapping, there are shortcomings: the three-layer thickness causes redundant material consumption and increases production costs; with the maturity of laser welding technology, in order to optimize the profile structure and enhance the competitiveness of enterprises, it is urgent to improve the traditional "dead edge wrapping" structure, reduce material consumption and simplify the structure while ensuring strength. Utility Model Content
[0004] This utility model provides a cabinet profile structure to solve the problems of the prior art.
[0005] The objective of this utility model can be achieved through the following technical solution: A cabinet profile structure includes a profile, the cross-section of which includes a first U-shaped fold-back section, a second U-shaped fold-back section, a first horizontal section, a first vertical section, and a second vertical section. The second U-shaped fold-back section is located inside the right side of the first U-shaped fold-back section, and the right end of the second U-shaped fold-back section is connected to the right end of the first U-shaped fold-back section. The right end of the first horizontal section is connected to the left end of the second U-shaped fold-back section and forms an inner cavity with the first U-shaped fold-back section. The left end of the first horizontal section is connected to the right side of the left end of the first U-shaped fold-back section by laser welding. The top of the left end of the first U-shaped fold-back section is connected inward to an arc-shaped connecting section with a plate thickness. The lower end of the first vertical section is connected to the arc-shaped connecting section. The upper end of the second vertical section is connected to the upper end of the first vertical section and is located to the right of the first vertical section.
[0006] As a further improvement, a water guide groove is provided on the inner side of the arc-shaped connecting section and the left end of the first horizontal section.
[0007] In a further improvement, both ends of the lower side of the first U-shaped fold segment and the second U-shaped fold segment are provided with arc-shaped chamfers. The right end of the second U-shaped fold segment is arc-shapedly connected to the right end of the first U-shaped fold segment. The right end of the first horizontal segment is arc-shapedly connected to the left end of the second U-shaped fold segment. The upper end of the second vertical segment is arc-shapedly connected to the upper end of the first vertical segment.
[0008] In a further improvement, the upper end of the arc-shaped connecting segment extends to the left and connects to a connecting segment with a plate thickness. The upper end of the connecting segment connects to the lower end of the first vertical segment, and the distance between the second vertical segment and the first vertical segment is a plate thickness.
[0009] Compared with the prior art, the beneficial effects of the cabinet profile structure of this utility model are as follows: By omitting the redundant sheet material of the traditional "dead edge" design, the material consumption of the overall profile is reduced by about 10%, lowering production costs. The integrated bending process ensures the integrity of the structure, and the high-strength connection of laser welding makes the profile's resistance to deformation and load-bearing capacity no less than that of the traditional structure, and even better due to the reduction of stress interference from redundant structures.

[0012] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.
[0013] Example 1 A cabinet profile structure includes a profile 1. The cross-section of the profile 1 includes a first U-shaped fold-back section 11, a second U-shaped fold-back section 12, a first horizontal section 13, a first vertical section 14, and a second vertical section 15. The second U-shaped fold-back section 12 is located inside the right side of the first U-shaped fold-back section 11, and the right end of the second U-shaped fold-back section 12 is connected to the right end of the first U-shaped fold-back section 11. The right end of the first horizontal section 13 is connected to the left end of the second U-shaped fold-back section 12 and forms an inner cavity 16 with the first U-shaped fold-back section 11. The left end of the first horizontal section 13 is connected to the right side of the left end of the first U-shaped fold-back section 11 by laser welding. The top of the left end of the first U-shaped fold-back section 11 is connected inward to an arc-shaped connecting section 17 with a plate thickness. The lower end of the first vertical section 14 is connected to the arc-shaped connecting section 17. The upper end of the second vertical section 15 is connected to the upper end of the first vertical section 14 and is located to the right of the first vertical section 14.
[0014] like Figures 1-2 As shown, the cabinet profile structure in this embodiment is optimized through a process of "integrated bending + laser welding".
[0015] The second vertical section 15, the first vertical section 14, the arc-shaped connecting section 17, the first U-shaped fold section 11, the second U-shaped fold section 12, and the first horizontal section 13 of the profile are formed using an integrated bending process. The bending process ensures the connection accuracy and structural continuity between the sections, avoiding the gap problems of traditional splicing structures.
[0016] The left end of the first horizontal segment 13 is connected to the right side of the left end of the first U-shaped fold segment 11 by laser welding. Compared with the traditional physical wrapping and fixing of "dead edge", laser welding has the advantages of small heat-affected zone, high connection strength, precise fixation of structure and no additional thickness.
[0017] The top left end of the first U-shaped fold-back section 11 is connected to an arc-shaped connecting section 17 with a plate thickness. Its core function is to omit the redundant plate material that extends upward from the first horizontal section in the traditional "dead edge wrapping" and to maintain the relative positioning relationship of key components such as the first horizontal section 13 and the second vertical section 15, so as to ensure that the dimensional accuracy of the profile assembly is not affected.
[0018] By omitting the redundant sheet material of the traditional "dead edge" design, the material consumption of the overall profile is reduced by about 10%, lowering production costs. The integrated bending process ensures the integrity of the structure, and the high-strength connection of laser welding makes the profile's resistance to deformation and load-bearing capacity no less than that of the traditional structure, and even better due to the reduction of stress interference from redundant structures.
[0019] As a further preferred embodiment, a water guide groove 18 is provided on the inner side of the arc-shaped connecting section 17 and the left end of the first horizontal section 13. Traditional nine-fold profile cabinets typically have closed or semi-closed cavities, lacking a dedicated drainage design. When condensation or accidental spills occur inside the cabinet, the liquid easily accumulates in the inner cavity or joint gaps of the profile, potentially leading to profile corrosion or moisture damage to electrical equipment over time. The groove structure formed by the arc-shaped connecting section 17 and the left end of the first horizontal section 13 guides the liquid entering the profile to the outside, achieving active drainage.
[0020] As a further preferred embodiment, both ends of the lower side of the first U-shaped bend segment 11 and the second U-shaped bend segment 12 are provided with arc-shaped chamfers. The right end of the second U-shaped bend segment 12 is arc-shapedly connected to the right end of the first U-shaped bend segment 11. The right end of the first horizontal segment 13 is arc-shapedly connected to the left end of the second U-shaped bend segment 12. The upper end of the second vertical segment 15 is arc-shapedly connected to the upper end of the first vertical segment 14. The hairpin bend process ensures the dimensional accuracy and structural continuity of the transition part without compromising the integrity of the profile. The arc-shaped chamfers and transitions avoid sharp edges, reducing the risk of personnel being scratched during production and assembly.
[0021] As a further preferred embodiment, the upper end of the arc-shaped connecting segment 17 extends to the left and connects to a connecting segment with a plate thickness. The upper end of the connecting segment connects to the lower end of the first vertical segment 14, and the distance between the second vertical segment 15 and the first vertical segment 14 is a plate thickness, where the thickness is 'a'. Figure 3 As shown.
[0022] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
