[0036] Example 1

[0037] This embodiment provides a switch cabinet. (Refer to...) Figures 1 to 5 As shown, the switch cabinet includes a first cabinet 100 and a second cabinet 200. The first cabinet 100 includes a first panel 11, and the second cabinet 200 includes a second panel 21. One end of the first panel 11 is provided with an inwardly bent first overlapping portion 111, and one end of the second panel 21 is provided with an inwardly bent second overlapping portion 211. The first overlapping portion 111 and the second overlapping portion 211 abut against each other, and the outer sides of the first overlapping portion 111 and the second overlapping portion 211 are fixedly connected by a third overlapping portion 212.

[0038] In this embodiment, the switch cabinet includes a first cabinet 100 and a second cabinet 200. In one implementation, the first cabinet 100 includes a first panel 11, and the second cabinet 200 includes a second panel 21. One end of the first panel 11 has an inwardly bent first overlapping portion 111, and one end of the second panel 21 has an inwardly bent second overlapping portion 211. The first overlapping portion 111 and the second overlapping portion 211 abut against each other and are fixedly connected by a third overlapping portion 212. The cooperative arrangement of the first overlapping portion 111, the second overlapping portion 211, and the third overlapping portion 212 enables rapid positioning and installation of the first cabinet 100 and the second cabinet 200, effectively improving assembly efficiency.

[0039] In this embodiment, the first overlapping part 111 abuts against the second overlapping part 211, and is then fixedly connected by the third overlapping part 212, positioning the first panel 11 and the second panel 21 to a flush state, thereby achieving rapid positioning of the first panel 11 and the second panel 21.

[0040] In this embodiment, the first overlapping portion 111 bends inward toward the inside of the first cabinet 100, and the second overlapping portion 211 bends inward toward the inside of the second cabinet 200. The inner and outer directions of the first cabinet 100 and the second cabinet 200 are shown in the attached drawings. Specifically, the inner direction is the direction on the side where the internal components are located, and the outer direction is the direction on the surface side.

[0041] In this embodiment, the end of the second overlapping part 211 is bent toward the second panel 21 to form a groove 2101, and the end of the third overlapping part 212 is bent and inserted into the groove 2101.

[0042] Specifically, when the first panel 11 and the second panel 21 are spliced ​​together, the first overlapping part 111 abuts against the second overlapping part 211, while the end of the third overlapping part 212 is bent and inserted into the groove 2101, so that the first overlapping part 111 and the second overlapping part 211 and the third overlapping part 212 and the groove 2101 are in contact and fit, thereby achieving reliable and effective positioning between the first panel 11 and the second panel 21.

[0043] Specifically, the third overlapping portion 212 and the second overlapping portion 211 are fixedly connected by a first fastener. For example, the first fastener is a first bolt and a first nut. The third overlapping portion 212 has a first mounting hole 2122, and the second overlapping portion 211 has a corresponding first connecting hole 2114. The first bolt passes through the first mounting hole 2122 and the first connecting hole 2114 and is threadedly connected to the first nut.

[0044] Specifically, multiple first fasteners, first mounting holes 2122, and first connecting holes 2114 are provided in a one-to-one correspondence to ensure a reliable and stable connection between the third overlapping part 212 and the second overlapping part 211.

[0045] This embodiment is not limited to this; the first fixing member can also be a screw, fixing pin, or other connecting member.

[0046] Specifically, the third overlapping part 212 is fixedly connected to the first overlapping part 111 by a second fastener.

[0047] For example, the second fastener is configured as a second bolt and a second nut. The third overlapping portion 212 has a second mounting hole 2123, and the first overlapping portion 111 has a corresponding second connecting hole 113. The second bolt passes through the second mounting hole 2123 and the second connecting hole 113 and is threadedly connected to the second nut.

[0048] Specifically, multiple second fasteners, second mounting holes 2123, and second connecting holes 113 are provided in a one-to-one correspondence to ensure a reliable and stable connection between the third overlapping part 212 and the first overlapping part 111.

[0049] This embodiment is not limited to this; the second fastener can also be a screw, a fixing pin, or other connecting component.

[0050] Specifically, the second overlapping portion 211 includes a first bending portion 2111, a second bending portion 2112, and a third bending portion 2113 connected in sequence. The first bending portion 2111 is connected to the second panel 21, and the third bending portion 2113 is opposite to the first bending portion 2111 and spaced apart by 122. The first bending portion 2111, the second bending portion 2112, and the third bending portion 2113 form a groove 2101, and the end of the first overlapping portion 211 abuts against the second bending portion 2112.

[0051] Specifically, the first bending portion 2111 and the second bending portion 2112 correspond to the two side walls of the groove 2101, respectively, and the second bending portion 2112 corresponds to the bottom of the groove 2101. The first bending portion 2111, the second bending portion 2112, and the third bending portion 2113 together form a U-shaped groove 2101 structure. Specifically, the first connecting hole 2114 is formed on the third bending portion 2113.

[0052] Specifically, the second panel 21, the first bending segment 2111, the third bending segment 2113, and the third overlapping segment 212 are arranged in parallel. Since the first bending segment 2111 and the third bending segment 2113 are parallel, and the first bend is parallel to the second panel 21, the third overlapping segment 212 is fixedly connected to the third bending segment 2113. The third overlapping segment 212 enables the first panel 11 and the second panel 21 to be in a parallel state, ensuring that the cabinet extends parallel as a whole.

[0053] Furthermore, a reinforcing portion 2121 is bent at one end of the third overlapping portion 212 facing the first panel 11. One side of the reinforcing portion 2121 is fixedly attached to the third overlapping portion 212, and the other side of the reinforcing portion 2121 is fixedly attached to the first overlapping portion 111. The reinforcing portion 2121 enhances the thickness of the third overlapping portion 212 facing the first overlapping portion 111, ensuring the connection strength between the first overlapping portion 111 and the third overlapping portion 212.

[0054] Furthermore, the first overlapping portion 111 is offset relative to the first panel 11 on the inner side of the first cabinet 100, forming a positioning recess 112, and the reinforcing portion 2121 is fixedly fitted into the positioning recess 112. Specifically, the reinforcing portion 2121 is fixedly fitted into the positioning recess 112, and an additional positioning contact is provided between the reinforcing portion 2121 and the positioning recess 112, further ensuring effective positioning between the first panel 11 and the second panel 21.

[0055] Example 2

[0056] This embodiment provides a switch cabinet. (Refer to...) Figures 6 to 8 As shown, the switch cabinet includes a first cabinet 100 and a second cabinet 200. The first cabinet 100 includes a third panel 12, and the second cabinet 200 includes a fourth panel 22. One end of the third panel 12 is provided with an inwardly bent fourth overlapping portion 121, and one end of the fourth panel 22 is provided with an outwardly bent fifth overlapping portion 221. The fifth overlapping portion 221 overlaps with the fourth overlapping portion 121, and the overlapping fourth overlapping portion 121 and the fifth overlapping portion 221 are fixed by a fixing structure.

[0057] Specifically, in this embodiment, the third panel 12 and the fourth panel 22 are quickly positioned together via the fourth overlapping portion 121 and the fifth overlapping portion 221. When the third panel 12 and the fourth panel 22 are joined, the fourth overlapping portion 121 and the fifth overlapping portion 221 are quickly fitted together, thereby achieving effective positioning of the fourth overlapping portion 121 and the fifth overlapping portion 221. Then, the fourth overlapping portion 121 and the fifth overlapping portion 221 are fixed by a fixing structure.

[0058] In this embodiment, the fourth overlapping portion 121 and the fifth overlapping portion 221 are arranged in parallel. When the third panel 12 and the fourth panel 22 are spliced, the parallel fourth overlapping portion 121 and the fifth overlapping portion 221 are fully fitted together, achieving rapid positioning of the fourth overlapping portion 121 and the fifth overlapping portion 221.

[0059] Specifically, when the third panel 12 and the fourth panel 22 are joined together, the third panel 12 and the fourth panel 22 are flush.

[0060] Furthermore, an extension portion 222 extends from the end of the fifth overlapping portion 221. The extension portion 222 is arranged parallel to the third panel 12 and is fixedly attached to the third panel 12. Specifically, when the third panel 12 and the fourth panel 22 are spliced ​​into place, the fourth overlapping portion 121 and the fifth overlapping portion 221 are fitted together, and the extension portion 222 is fitted to the inner side of the third panel 12, thus achieving two points of contact and engagement. These two points of contact and engagement achieve the splicing and positioning between the third panel 12 and the fourth panel 22. The structure is simple and has a reliable positioning effect.

[0061] For example, the fixing structure includes a third bolt and a third nut. The third panel 12 has a third connecting hole 123, and the fourth panel 22 has a third mounting hole 2221. The third bolt passes through the third mounting hole 2221 and is threadedly connected to the third connecting hole 123 and the third nut.

[0062] Multiple third bolts, third nuts, third mounting holes 2221, and third connecting holes 123 are provided one-to-one to ensure a reliable and secure connection between the third panel 12 and the fourth panel 22.

[0063] This embodiment is not limited to this; the fixing structure can also be set as screws, fixing pins, or other connecting parts.

[0064] This embodiment also provides a switch cabinet. (Refer to...) Figure 9 As shown, the switch cabinet includes a first cabinet 100, a second cabinet 200, an instrument room, and a current transformer. The instrument room is located in the first cabinet 100, and the current transformer is located in the second cabinet 200.

[0065] Specifically, the instrument room contains low-voltage components for the switchgear. In addition to the instrument room, the first cabinet 100 also contains a handcart compartment, which contains floor-mounted circuit breakers and valve mechanisms. In addition to current transformers, the second cabinet 200 also contains contact boxes, grounding switches, wall bushings, and main busbars.

[0066] In this embodiment, the switch cabinet has a simple overall structure, is easy and reliable to assemble, and effectively ensures assembly efficiency. The front and rear cabinets can be directly spliced ​​together after assembly, without the need for further assembly of other components.

[0067] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
