Technical Field

[0001] This utility model relates to the field of electrical cabinets, and in particular to a modularly assembled electrical cabinet structure. Background Technology

[0002] Electrical cabinets, as core supporting devices in the field of electrical equipment, are mainly used for the centralized installation and protection of various electrical components, circuits, and control modules. They are widely used in industrial production, power transmission, construction engineering, automated control systems, and many other fields. Through a reasonable spatial layout and protective design, their internal components provide a stable working environment for electrical parts, effectively preventing interference from external dust, moisture, collisions, and other factors, ensuring the safe and stable operation of the electrical system, and serving as an important foundation for the normal functioning of electrical equipment.

[0003] In practical applications, the volume requirements for electrical cabinets vary significantly depending on the project and installation environment. However, traditional electrical cabinets are mostly designed as a single, integrated unit, with their volume fixed after manufacturing. This makes it impossible to flexibly adjust them according to actual needs such as on-site installation space, the number of electrical components, and their layout. This necessitates customizing or purchasing electrical cabinets of different sizes for different usage scenarios, increasing equipment procurement costs and inventory management pressure. Furthermore, it reduces the versatility of electrical cabinets, making them unsuitable for diverse and personalized installation and usage needs, causing considerable inconvenience to users. Therefore, this application proposes a modular assembly electrical cabinet structure to address these issues. Utility Model Content

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a modularly assembled electrical cabinet structure includes a bottom cabinet 1, a top cabinet 2, and a middle cabinet 3. The middle cabinet 3 is installed between the bottom cabinet 1 and the top cabinet 2. Two mounting brackets 4 are symmetrically fixedly installed at both ends of the bottom cabinet 1 and the top cabinet 2 near the middle cabinet 3. Four mounting brackets 4 are symmetrically fixedly installed at both ends of the middle cabinet 3 near the bottom cabinet 1 and the top cabinet 2. Each mounting bracket 4 consists of a support frame 7 and a fixing shaft 8. The fixing shaft 8 is fixedly installed on the inner wall of the support frame 7. A connecting structure 5 is rotatably installed on each of the two upper mounting brackets 4 installed on the middle cabinet 3. The connecting structure 5 is also installed on the mounting brackets 4 installed on the top cabinet 2. A connecting structure 5 is also rotatably installed on each of the two mounting brackets 4 installed on the bottom cabinet 1. The connecting structure 5 is also installed on the lower mounting brackets 4 on the middle cabinet 3. The connecting structure 5 consists of a connecting plate 9, a support plate 11, a connecting column 13, a moving plate 15, a mounting plate 17, a bolt 19, and a plug plate 20. The support plate 11 is fixedly installed at one end of the connecting plate 9, the connecting column 13 is fixedly installed at one end of the support plate 11, the movable plate 15 is set above the support plate 11, the mounting plate 17 is fixedly installed at one end of the movable plate 15, the mounting plate 17 has a through groove 18, the connecting column 13 has a threaded hole 14, the bolt 19 passes through the through groove 18 and is threadedly connected to the connecting column 13, there are two insert plates 20 which are symmetrically fixedly installed at one end of the movable plate 15, and two guide rail grooves 12 are symmetrically opened at one end of the connecting plate 9, the insert plates 20 are slidably inserted into the support plate 11 through the guide rail grooves 12. The bottom cabinet 1, top cabinet 2, and middle cabinet 3 are all equipped with protective doors 6 at their front ends. By setting up an electrical cabinet consisting of the bottom cabinet 1, top cabinet 2, and middle cabinet 3, and using mounting brackets 4 and connecting structures 5 to assemble and disassemble the middle cabinet 3 with the bottom cabinet 1 and top cabinet 2, the middle cabinet 3 can be flexibly disassembled and assembled according to the number of electrical components and the size of the installation space required in the actual usage scenario. This allows for free adjustment of the electrical cabinet volume, eliminating the need to customize electrical cabinets of specific sizes for different scenarios, greatly improving the equipment's versatility and adaptability, and effectively reducing procurement costs and inventory management pressure. The presence of mounting brackets 4 and connecting structures 5 enables quick assembly and disassembly between adjacent cabinets, making the installation and disassembly process simple and efficient. Simultaneously, each cabinet is independently equipped with a protective door 6, ensuring the protection of the electrical components inside each cabinet while achieving modular adjustment, preventing external interference such as dust and moisture, and ensuring the safe and stable operation of the electrical system.

[0015] Specifically, the upper end of the middle cabinet 3 contacts the lower end of the top cabinet 2, and the lower end of the middle cabinet 3 contacts the upper end of the bottom cabinet 1. The support frame 7 on the mounting bracket 4 is fixedly installed at one end of the bottom cabinet 1, the top cabinet 2, or the middle cabinet 3 by screws. The fixed shaft 8 is fixedly connected to the support frame 7 by screws. The connecting plate 9 on the connecting structure 5 has a shaft hole 10. The connecting plate 9 is rotatably installed on the fixed shaft 8 of the mounting bracket 4 installed on the middle cabinet 3 or the bottom cabinet 1 through the shaft hole 10. Two guide rail grooves 12 are symmetrically opened at one end of the connecting plate 9. The connecting column 13 has a threaded hole 14. One end of the moving plate 15 on the connecting structure 5 has an arc groove 16. The moving plate 15 is sleeved on the fixed shaft 8 of the mounting bracket 4 installed on the middle cabinet 3 or the top cabinet 2 through the arc groove 16. The mounting plate 17 on the connecting structure 5 has a through groove 18. The bolt 19 is rotatably installed in the through groove 18. The bolt 19 is also installed on the mounting plate 17 on the connecting structure 5. Inside the threaded hole 14, the insert plate 20 is movably inserted into the guide rail groove 12. When using this modularly assembled electrical cabinet structure, if the number of electrical components is small and the installation space is limited, the intermediate cabinet 3 needs to be disassembled. The operation steps are as follows: First, loosen the bolt 19 on the connecting structure 5 so that the bolt 19 rotates in the through groove 18 of the mounting plate 17 and moves upward a distance along the threaded hole 14 on the connecting column 13; then push the moving plate 15 upward so that its arc groove 16 disengages from the fixed shaft 8. At this time, the insert plate 20 at one end of the moving plate 15 will slide upward in the guide rail groove 12 of the connecting plate 9; then rotate the connecting plate 9 so that the connecting structure 5 rotates downward around the fixed shaft 8 of the mounting frame 4 through the shaft hole 10, thereby releasing the connection between the bottom cabinet 1 and the intermediate cabinet 3, and between the intermediate cabinet 3 and the top cabinet 2; finally, remove the intermediate cabinet 3 directly and re-fix the bottom cabinet 1 and the top cabinet 2 through the connecting structure 5 to complete the disassembly and adjustment.

[0016] If there are many electrical components and sufficient installation space, an intermediate cabinet 3 needs to be installed. The following steps can be followed: First, following the reverse process of disassembly described above, loosen the connecting structure 5 between the bottom cabinet 1 and the top cabinet 2; then place the intermediate cabinet 3 between the bottom cabinet 1 and the top cabinet 2, ensuring that the lower end of the intermediate cabinet 3 is in close contact with the upper end of the bottom cabinet 1 and the upper end is in close contact with the lower end of the top cabinet 2; then rotate the connecting structure 5 connecting the mounting bracket 4 on the bottom cabinet 1 and the intermediate cabinet 3, so that the connecting structure 5 rotates upward around the fixed shaft 8 of the mounting bracket 4 through the shaft hole 10 until the movable plate 15 on the connecting structure 5 is aligned with the upper part of the fixed shaft 8 of the adjacent mounting bracket 4; then push the movable plate 15 so that the arc groove 16 is accurately fitted onto the fixed shaft 8 of the adjacent mounting bracket 4; finally, tighten the bolts 19 to complete the stable connection between the intermediate cabinet 3 and the bottom cabinet 1 and the top cabinet 2, and then it can be put into use.

[0017] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
