[0014] Example 1:

[0015] This embodiment provides a frame structure for a ring main unit, including two frame components 1 and four support members 2. Each of the two frame components 1 includes: Four fixed profiles 11 are arranged in a rectangle and connected end to end. Each of the two ends of the fixed profile 11 is provided with a slot 12 and a snap-fit ​​part 13. Two adjacent fixed profiles 11 are spliced ​​together through the slot 12 and the snap-fit ​​part 13. Support member 2 includes: Support part 21, the support part 21 is a cylindrical structure and the cross section along the Z direction is rectangular; Two connecting parts 22 are integrally connected to the support part 21 and are arranged in an "L" shape in the cross section along the Z direction. The connecting parts 22 are connected and fixed by fasteners and fixing profiles 11. The snap-fit ​​part 13 is also integrally connected with a connecting pin 14, which is arranged along the Z direction and is inserted into the support part 21.

[0016] In this technical solution, the two frame components 1 are a top frame and a bottom frame, respectively. Each frame component 1 is assembled from four fixed profiles 11. At both ends of the fixed profile 11 along its length, there are matching slots 12 and engaging parts 13. The slots 12 and engaging parts 13 can be triangular structures. By splicing the engaging part 13 at one end of the fixed profile 11 with the slot 12 at the end of the other fixed profile 11, as shown... Figure 3 As shown, four fixed profiles 11 are spliced ​​together end to end to form the frame component 1.

[0017] Each fixed profile 11 has a connecting post 14 on its snap-fit ​​portion 13. The support member 2 consists of a support portion 21 and two symmetrically arranged connecting portions 22. The connecting posts 14 and the support portions 21 are inserted into each other along the Z-direction, allowing all four support members 2 to be installed on the bottom frame. Fasteners are then used to pass through the connecting portions 22 of the support members 2 to connect and fix the connecting portions 22 to the bottom frame. Then, the top frame is also connected to the other end of the support member 2 using the connecting posts 14. Fasteners are then used to pass through the connecting portions 22 of the support members 2 to connect and fix the connecting portions 22 to the top frame, thus completing the installation and fixing of the ring main unit's frame structure.

[0018] Through the above structural design, the ring main unit frame consists of a top frame, a bottom frame, and four support members 2. Both the top and bottom frames are assembled from four fixed profiles 11 connected by fitting joints and slots 12. The structure is simple and convenient for production and processing. Furthermore, the connecting posts 14 on the fixed profiles 11 and the four support members 21 are used to fix and position the connection between the frame assembly 1 and the support members 2, enhancing stability and making assembly operations more convenient, effectively improving production efficiency.

[0019] Example 2:

[0020] This embodiment provides a frame structure for a ring main unit, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0021] Furthermore, support member 2 also includes: The reinforcing rib 23 is integrally connected to the support portion 21 and is arranged along the Z direction. The reinforcing rib 23 divides the interior of the support portion 21 into a first chamber and a second chamber.

[0022] The support section 21 is internally divided into a first chamber and a second chamber by reinforcing ribs 23. Both the first and second chambers are triangular prisms, and the connecting post 14 is also designed to be a matching triangular prism. This structural design enhances the internal structural strength of the support section 21, thereby improving the stability of the support.

[0023] Example 3:

[0024] This embodiment provides a frame structure for a ring main unit, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0025] Furthermore, it also includes mounting beams 3, which are fixedly connected by fasteners and connecting parts 22. By setting several mounting beams 3 on the frame, it is possible to install and fix partitions on the mounting beams 3, and by setting multiple partitions, the internal space of the frame is divided into multiple storage chambers.

[0026] Furthermore, the connecting part 22 is provided with several mounting holes 24 equidistantly arranged along the Z direction. Through this structural design, the mounting height of the mounting beam 3 in the frame along the Z direction can be adjusted to adapt to the space size of each storage chamber, thereby enabling compatibility with the use of ring main units of different models and specifications, effectively improving adaptability.

[0027] Example 4:

[0028] This embodiment provides a frame structure for a ring main unit, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0029] Furthermore, the connecting part 22 is also provided with a positioning part 25, and the cross section of the positioning part 25 along the Z direction is a "V" shaped structure; The fixed profile 11 is provided with a positioning protrusion 15, and the positioning protrusion 15 and the positioning part 25 are inserted and engaged in the Z direction.

[0030] The positioning part 25 has a "V" shaped cross section along the Z direction, forming a "V" shaped positioning groove 26. The positioning protrusion 15 on the fixing profile 11 and one end of the positioning groove 26 are inserted and matched to achieve a further positioning and stabilizing effect, thereby effectively enhancing the structural stability.

[0031] Furthermore, a limiting end face 27 is provided on the positioning part 25, which is used to abut against the end of the mounting beam 3. The positioning part 25 has a limiting end face 27 perpendicular to the fixing profile 11. When the mounting beam 3 is installed, the end of the mounting beam 3 abuts against the limiting end face 27, which serves two purposes: firstly, it provides a limiting effect, facilitating disassembly and assembly; secondly, it ensures that the mounting beam 3 remains perpendicular to the support member 2 when installed on the frame, ensuring that it remains horizontal when the partition is subsequently installed, thus improving its practicality.
