[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] Example 1

[0035] This embodiment discloses a switch cabinet. Figure 1 and Figure 2 A switch cabinet includes a cabinet body 1, a busbar frame 2 is provided on the cabinet body 1, and the busbar frame 2 includes a first stainless steel bar 21 and a second stainless steel bar 22. A fixing component 3 is provided on the busbar frame 2 for fixing the first stainless steel bar 21 and the second stainless steel bar 22.

[0036] Reference Figure 1 and Figure 2 The fixing assembly 3 includes a plurality of fixing bolts 31 and a plurality of fixing posts 311. The fixing posts 311 are fixedly connected to the surface of the first stainless steel bar 21. The surface of the second stainless steel bar 22 is provided with through-holes 23 for the fixing bolts 31 to pass through. The fixing bolts 31 are threadedly connected to the fixing posts 311 through the through-holes 23, thereby fixing the first stainless steel bar 21 and the second stainless steel bar 22 to each other.

[0037] Reference Figure 2 The busbar frame 2 is provided with a plurality of copper busbars 11. A plurality of placement grooves 231 are formed on the surfaces of the first stainless steel bar 21 and the second stainless steel bar 22. The placement grooves 231 are arranged in an array along the length of the first stainless steel bar 21, and the placement grooves 231 are arranged in an array along the length of the second stainless steel bar 22. The placement grooves 231 are for inserting the copper busbars 11.

[0038] The implementation principle of Example 1 is as follows: the fixing bolt 31 is threadedly connected to the fixing column 311 through the through hole 23 to achieve mutual fixation of the first stainless steel bar 21 and the second stainless steel bar 22.

[0039] Example 2

[0040] Reference Figure 3 and Figure 4 This embodiment differs from the first embodiment in that the fixing assembly 3 includes two fixing bars 242 and two stopper covers 32. The two stopper covers 32 are located on different sides of the first stainless steel bar 21 and the second stainless steel bar 22. Two grooves 24 are defined on the surface of the first stainless steel bar 21. A fixing spring 241 is fixedly connected to the bottom wall of the groove 24. The fixing spring 241 is fixedly connected to the fixing bar 242 on the surface away from the bottom wall of the groove 24.

[0041] Reference Figure 4 The second stainless steel bar 22 has two fixing holes 25 on its surface for inserting the fixing bars 242. A movable bar 251 is slidably connected to the fixing holes 25, and a fixing spring 241 drives the fixing bar 242 into the fixing holes 25. When the fixing bar 242 is inserted into the fixing holes 25, the fixing spring 241 is in a non-stressed state, and the movable bar 251 protrudes from the fixing holes 25. When the fixing bar 242 is not inserted into the fixing holes 25, the fixing spring 241 is in a compressed state, and the movable bar 251 can be completely located in the fixing holes 25.

[0042] Reference Figure 4 The side of the stopper cover 32 defines a receiving groove 321 for inserting the first stainless steel bar 21 and the second stainless steel bar 22. The wall of the receiving groove 321 defines a moving groove 322 for inserting the moving bar 251. When the fixing bar 242 is inserted into the fixing hole 25, the moving bar 251 protrudes from the fixing hole 25 and can be inserted into the moving groove 322, thereby securing the stopper cover 32 and the second stainless steel bar 22 to each other.

[0043] Reference Figure 4 and Figure 5 The stopper cover 32 has a rotation hole 33 formed on its surface, communicating with the receiving groove 321. A rotation plate 331 is rotatably connected to the rotation hole 33. A through hole 332 is formed on the surface of the rotation plate 331. An annular groove 333 is formed on the wall of the through hole 332, extending along the circumference of the through hole 332. A limit bar 34 is slidably connected to the through hole 332. A ring plate 341 is fixedly connected to the outer surface of the limit bar 34 and slidably connected to the annular groove 333.

[0044] Reference Figure 4A limiting spring 342 is sleeved on the limiting bar 34. One end of the limiting spring 342 is fixedly connected to the ring plate 341, and the other end of the limiting spring 342 is fixedly connected to the groove wall of the annular groove 333. The limiting spring 342 drives the limiting bar 34 to move toward the fixing bar 242. The fixing bar 242 has a limiting groove 243 on its surface for the limiting bar 34 to be inserted into.

[0045] Reference Figure 4 and Figure 5 When the limiting strip 34 is inserted into the limiting groove 243, the limiting spring 342 is in a non-stressed state, and the fixing strip 242 is located in the fixing hole 25. When the limiting strip 34 is not inserted into the limiting groove 243, the limiting spring 342 is in a compressed state, and the rotating plate 331 can rotate in the rotating hole 33.

[0046] The implementation principle of Example 2 is as follows: the staff pulls the limiting bar 34 to disengage the limiting bar 34 from the limiting groove 243, the staff rotates the rotating plate 331, and the staff then pulls the fixing bar 242 to disengage the fixing bar 242 from the fixing hole 25. At this time, the stop cover 32 can be separated from the first stainless steel bar 21 and the second stainless steel bar 22. Finally, the staff removes the second stainless steel bar 22 from the first stainless steel bar 21.
