[0031] First embodiment:
[0032] This embodiment discloses a frame connection structure.
[0033] like Figure 1 As shown, the frame connection structure includes a cuboid frame 1 and a tee connector 2.
[0034] like Figures 1-3 As shown, the cuboid frame 1 is enclosed by four horizontal beams 11 symmetrically arranged along the X-axis, four vertical beams 12 symmetrically arranged along the Y-axis, and four vertical beams 13 symmetrically arranged along the Z-axis. Each of the horizontal beams 11, vertical beams 12, and vertical beams 13 has an internal cavity 14. Eight tee connectors 2 are provided, each located at a corner of the cuboid frame 1. Each tee connector 2 connects to an adjacent horizontal beam 11, vertical beam 12, and vertical beam 13, and includes a shaft head 21, a first shaft body 22, a second shaft body 23, and a third shaft body 24. The shaft head 21 is cuboid. The first shaft body 22 is located on the side of the shaft head 21 facing the X-axis, and is inserted into the cavity 14 of the horizontal beam 11 from the left and right ends of the horizontal beam 11 and bolted to the horizontal beam 11. The second shaft body 23 is located on the side of the shaft head 21 facing the Y-axis, and is inserted into the cavity 14 of the vertical beam 12 from the front and rear ends of the vertical beam 12 and bolted to the vertical beam 12. The third shaft 24 is located on the side of the shaft head 21 facing the Z-axis direction, and is inserted into the cavity 14 of the vertical beam 13 from the upper and lower ends of the vertical beam 13 and bolted to the vertical beam 13.
[0035] For example, the crossbeam 11, longitudinal beam 12, and vertical beam 13 are made of nine-fold or five-fold profiles. The first shaft 22, the second shaft 23, and the third shaft 24 have screw holes 25 facing the inside of the cuboid frame 1. Square holes 15 are opened on the crossbeam 11, longitudinal beam 12, and vertical beam 13 at the corresponding screw holes 25, and the screw holes 25 are exposed in the square holes 15.
[0036] Furthermore, the width of the shaft head 21 is greater than the inner diameter of the cavity 14, and the two ends of the crossbeam 11, longitudinal beam 12 and vertical beam 13 respectively abut against the surface of the shaft head 21, improving the connection strength and appearance of the cuboid frame 1.
[0037] In this embodiment, a first shaft body 22 is provided on the side of the shaft head 21 facing the X-axis, a second shaft body 23 is provided on the side of the shaft head 21 facing the Y-axis, and a third shaft body 24 is provided on the side of the shaft head 21 facing the Z-axis. The first shaft body 22, the second shaft body 23, and the third shaft body 24 are respectively inserted into the cavities 14 of the adjacent crossbeams 11, longitudinal beams 12, and vertical beams 13. At the same time, the crossbeams 11, longitudinal beams 12, and vertical beams 13 are bolted to the first shaft body 22, the second shaft body 23, and the third shaft body 24, respectively. The frame connection structure is simple and easy to install and disassemble.
[0038] Second embodiment:
[0039] Based on the first embodiment, the second embodiment further optimizes and refines the frame connection structure.
[0040] like Figure 1 , Figures 4-6 As shown, the frame connection structure further includes a mounting plate 3, which is mounted between the four longitudinal beams 12 along the X-axis.
[0041] For example, mounting plate 3 is made of aluminum-zinc-magnesium steel plate. Zinc in the alloy coating provides sacrificial protection, aluminum provides passivation protection, and the addition of magnesium activates the alloy coating. Together with zinc and aluminum, it reduces the rate of coating wear, forming an insulating protective layer at the cut and cross-section, providing barrier protection within the coating and significantly improving the corrosion resistance of the coated steel. The frame connection structure also includes a first connecting block 31 and a second connecting block 32. There are two first connecting blocks 31, with their upper ends bolted to the second shaft 23 located within the upper longitudinal beam 12 of the cuboid frame 1, and their lower ends bolted to the top two sides of the front end of mounting plate 3. There are two second connecting blocks 32, with their lower ends bolted to the second shaft 23 located within the lower longitudinal beam 12 of the cuboid frame 1, and their upper ends bolted to the bottom two sides of the rear end of mounting plate 3. Specifically, the first connecting block 31 includes a first plate 311 vertically arranged along the Y-axis, a second plate 313 horizontally arranged, and a third plate 314 vertically arranged along the X-axis. The first plate 311 has hooks 312 on both sides along the Y-axis, which engage with square holes 15. Simultaneously, bolts pass through the first plate 311 and square holes 15 to threadedly connect with the second shaft 23, preventing the mounting plate 3 from deflecting. The second plate 313 connects the lower end of the first plate 311 and the upper end of the third plate 314. Bolts pass through the third plate 314 and mounting plate 3 to threadedly connect with nuts, fixing the mounting block and the third plate 314 together. The second connecting block 32 includes a fourth plate 321, a first right-angle block 322, and a second right-angle block 323. Bolts pass through the fourth plate 321 and square holes 15 to threadedly connect with the second shaft 23. The first right-angle block 322 connects to the fourth plate 321 on the side and abuts against the side of the longitudinal beam 12. The second right-angle block 323 is set on the upper end of the first right-angle block 322. The lower end of the mounting plate 3 is supported inside the first right-angle block 322. The bolt passes through the mounting plate 3 and the first right-angle block 322 and is threadedly connected to the nut to fix the mounting plate 3 and the first right-angle block 322 together, which provides good support for the mounting plate 3.
[0042] In this embodiment, the first connecting block 31 is bolted to the top two sides of the front end of the mounting plate 3, and the upper end of the first connecting block 31 is bolted to the second shaft 23 located in the upper longitudinal beam 12 of the cuboid frame 1. The second connecting block 32 is bolted to the bottom two sides of the rear end of the mounting plate 3, and the lower end of the second connecting block 32 is bolted to the second shaft 23 located in the lower longitudinal beam 12 of the cuboid frame 1, which facilitates the installation and disassembly of the mounting plate 3.
[0043] Third embodiment:
[0044] This embodiment discloses a combiner cabinet 4.
[0045] like Figure 7 As shown, the junction box 4 includes a frame connection structure, side panels 41, door panels 43, top cover 42, and bottom plate.
[0046] The frame connection structure is as described in the first or second embodiment. Side panels 41 are fixed to both sides of the frame connection structure. Door panels 43 are hinged to the front end of the frame connection structure. Top cover 42 is fixed to the upper end of the frame connection structure. Bottom plate is fixed to the lower end of the frame connection structure. For example, the side panels 41, top cover 42, and bottom plate are respectively fixed to the sides, top, and bottom of the cuboid frame 1 by bolts and rivet nuts, and the bolts are then secured with nuts or thread-locking adhesive to prevent loosening.
[0047] like Figure 7 As shown, the combiner cabinet 4 further includes a base 44, which is fixed between the lower end of the frame connection structure and the upper end of the base plate.
[0048] like Figure 7 and Figure 8 As shown, the combiner cabinet 4 further includes lifting lugs 45, which are located at the four corners of the upper end of the cuboid frame 1 to facilitate the lifting and transportation of the combiner cabinet 4. The lifting lugs 45 include a screw 452 and a ring 451. The screw 452 passes through the top cover 42 and is threadedly connected to the shaft head 21, and the ring 451 is located at the upper end of the screw 452.
[0049] In this embodiment, by fixing the side panel 41, top cover 42 and bottom plate to the two sides, top and bottom of the frame connection structure respectively, and hinge the door panel 43 to the front end of the frame connection structure, the junction box 4 is easy to install and has a high degree of integration.
[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
