[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1-4 This utility model provides a technical solution: a square frame profile, including a profile body 1, the profile body 1 including a frame 101, the profile body 1 having a first through groove 102 and a second through groove 103 that pass through from left to right, when the electrical cabinet frame 101 is assembled, the corner connectors on the tee connectors pass through into the interior of the first through groove 102, the number of second through grooves 103 is set to two, the top of the frame 101 is provided with a reinforcing plate 104, the cross-section of the frame 101 and the reinforcing plate 104 after combination is triangular, the reinforcing plate 104 is made of sheet metal bending, in the electrical cabinet frame When in use, its corrosion resistance far exceeds that of traditional cabinets. The reinforcing plate 104 is provided with two first connecting plates 3. The shape of the first connecting plates 3 is set as L. By setting the reinforcing plate 104, and combining the frame 101 and the reinforcing plate 104 into a triangle, the overall compressive strength of the profile body 1 is improved, and the stress is greater than that of traditional cabinet profiles. The setting of the first through groove 102 and the second through groove 103 reduces the cost and makes the overall weight lighter, which facilitates transportation. The two first connecting plates 3 are the two ends of the reinforcing plate 104, so that the two ends of the first connecting plate 3 under stress are not easy to bend.

[0023] Reference Figure 1-4 The front and top sides of the reinforcing plate 104 are provided with several through slots 4, which are arranged in a horizontal array along the axis. The front and top sides of the reinforcing plate 104 are also provided with several through holes 5, which are arranged in a horizontal array along the axis. The through slots 4 and through holes 5 are staggered. By setting through slots 4 and through holes 5, materials can be saved, and the stress distribution of the profile can be changed. When subjected to external force, it is easier to undergo a certain degree of deformation, thereby absorbing and dispersing energy. When used in electrical cabinets, it can also increase the contact area between the profile body 1 and the air, improve heat dissipation efficiency, and can be connected to the electrical cabinet beam through through slots 4 and through holes 5, improving the connection stability.

[0024] Reference Figure 1-4The profile body 1 is provided with a second connecting plate 6. The second connecting plate 6 is integrally formed with two first protrusions 7. The included angle between the first protrusions 7 and the second connecting plate 6 is 90 degrees. The first connecting plate 3 is located in the included angle between the first protrusions 7 and the second connecting plate 6. By setting the first protrusions 7, when the electrical cabinet frame 101 is subjected to external force, since the first connecting plate 3 is located in the included angle between the first protrusions 7 and the second connecting plate 6, the weaker two-end connection points of the first connecting plate 3 will not be directly subjected to force, thus increasing its force-bearing area.

[0025] Reference Figure 1-4 The profile body 1 is provided with two third connecting plates 8, and the third connecting plate 8 is provided with a second protrusion 9. The included angle between the third connecting plate 8 and the second protrusion 9 is 90 degrees. The first connecting plate 3 is located in the included angle between the second protrusion 9 and the third connecting plate 8. By providing the second protrusion 9, since the first connecting plate 3 is also located in the included angle between the third connecting plate 8 and the second protrusion 9, the force-bearing area is increased, and the first connecting plate 3 can be limited and fixed.

[0026] Reference Figure 1-4 The profile body 1 is made of aluminum alloy and is formed by one-time extrusion of aluminum rods. This makes the internal metal crystal structure of the profile body 1 more uniform and continuous, and the surface smooth and flat. Compared with profiles that are spliced ​​or processed multiple times, the profile body 1 formed in one piece avoids welding defects such as porosity and slag inclusions that may occur in these locations, and there is no stress concentration problem caused by the connection. The profile body 1 is provided with two third protrusions 10, and the second through groove 103 is set inside the third protrusions 10. By setting the third protrusions 10, the profile body 1 can effectively increase its torsional resistance. When the electrical cabinet is subjected to external forces, such as collisions, vibrations or uneven loads, it can effectively disperse stress. In addition, the setting of the second through groove 103 can save costs and also allow cables to be laid inside it, avoiding the cables being exposed on the outside.

[0027] Specifically, the working process or principle of this square frame profile is as follows: In use, the combination of frame 101 and reinforcing plate 104 forms a triangle, improving the overall compressive strength of the profile body 1. The first through groove 102 and the second through groove 103 reduce costs. The two first connecting plates 3 serve as the two ends of the reinforcing plate 104, preventing bending at the stressed ends of the first connecting plates 3. The through groove 4 and through hole 5 save materials and alter the stress distribution of the profile, making it more prone to deformation under external force, thus absorbing and dispersing energy. When used in electrical cabinets, it also increases the contact area between the profile body 1 and air, improving heat dissipation efficiency. When the electrical cabinet frame 1... When subjected to external force, the first connecting plate 3 is located in the angle between the first protrusion 7 and the second connecting plate 6, so that the weaker connection at both ends of the first connecting plate 3 will not be directly subjected to force, thus increasing its force-bearing area. Since the first connecting plate 3 is also located in the angle between the third connecting plate 8 and the second protrusion 9, the force-bearing area is increased while the first connecting plate 3 can be limited and fixed. The setting of the third protrusion 10 can effectively increase the torsional resistance of the profile body 1. When the electrical cabinet is subjected to external forces, such as collisions, vibrations or uneven loads, it can effectively disperse stress. In addition, the setting of the second through groove 103 can save costs and also allow the cable to be laid inside, avoiding the cable being exposed on the outside.
