[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0019] like Figure 1-5 The circuit breaker cabinet structure shown includes a sheet metal cabinet box 1 and a mounting frame 3. In this embodiment, the mounting frame 3 is detachably mounted relative to the sheet metal cabinet box 1. The mounting frame 3 is used for the installation of electrical components inside the circuit breaker cabinet. The sheet metal cabinet box 1 forms an internal cavity through a door and a panel. The front of the sheet metal cabinet box 1 is provided with an opening and closing door 2 for opening or closing the internal cavity. Two wheel grooves 13 are also provided at the bottom of the internal cavity of the sheet metal cabinet box 1. The mounting frame 3 is provided with pulleys 31. The mounting frame 3 is movably mounted relative to the sheet metal cabinet box 1 through the pulleys 31. In use, the pulleys 31 can slide into the sheet metal cabinet box 1 along the wheel grooves 13. The wheel grooves 13 not only facilitate the sliding and positioning of the pulleys 31, but also restrict the left and right movement of the mounting frame 3 within the sheet metal cabinet box 1. In addition, based on the circuit breaker cabinet having side expansion sleeves and other features, the mounting frame 3 is detachably mounted to facilitate easy removal.

[0020] As a further feature of the above scheme, the side expansion mounting plate 32 is fixedly connected to the mounting cabinet 3, and is also provided with mounting hole groove 321. The sheet metal cabinet box 1 is provided with a groove 16 that matches the side expansion mounting plate 32. The opening and closing door 2 includes a side opening door 21 and a flip door 22. The side opening door 21 is provided with a side opening hinge 211 on one side to flip open horizontally, and the flip door 22 is provided with a flip hinge 221 at the upper end to flip open upward.

[0021] As described above, in this embodiment, the side panel 11 of the sheet metal cabinet 1 is also provided with a viewing window groove 12, and the mounting frame 3 is provided with a side expansion mounting plate 32 that matches the viewing window groove 12. Figure 1 , Figure 2As shown, when the mounting frame 3 moves out relative to the sheet metal cabinet 1, the side expansion mounting plate 32 moves horizontally with the mounting frame 3. During installation, the side expansion mounting plate 32 is inserted into the side plate 11, and the mounting hole groove 321 of the side expansion sleeve on the side expansion mounting plate 32 corresponds to the window groove 12. Furthermore, in order to prevent the electrical components connected to the side expansion mounting plate 32 from colliding with the opening and closing door 2 when it moves out, the opening and closing door 2 in this embodiment is provided as described above as a flip door 22. The flip door 22 flips and swings upward relative to the sheet metal cabinet 1 bracket by the flip hinge 221 provided in the upper part, thereby releasing the side plates 11 on both sides so that the side expansion mounting plate 32 that comes out from the front will not touch the flip door 22. Furthermore, the flip door 22 can also refer to the design of the flip door 22 in the prior art, and set a triangular rod support or existing limit structure design on it so that it can maintain the upward flipped open state, which facilitates the removal of the mounting frame 3.

[0022] As a further feature of the above scheme, the wheel groove 13 is provided with a beveled surface 14 at one end relative to the opening and closing door 2. The beveled surface 14 is provided in front of the wheel groove 13 on the front of the sheet metal cabinet 1, forming a guide ramp surface for the pulley 31 to enter the cavity inside the sheet metal cabinet 1 more easily. It is worth noting that the vertical width of the groove 16 is greater than that of the side expansion mounting plate 32, so that the mounting frame 3 can enter the sheet metal cabinet 1 smoothly when it is in an inclined state through the beveled surface 14.

[0023] Furthermore, a limiting groove 15 is provided in the wheel groove 13. The pulley 31 slides into the limiting groove 15. The limiting groove 15 is used to position and limit its installation position. During use, the pulley 31 rolls in along the wheel groove 13. When it reaches the limiting groove 15, the pulley 31 will be engaged along the wheel groove 13, causing the mounting cabinet 3 to move downward a short distance as a whole. This allows the pulley 31 to be engaged in the limiting groove 15, thus keeping the mounting cabinet 3 in the predetermined installation position. The fixing pin 35 provided on the mounting cabinet 3 can be aligned with the fixing hole plate 36 on the sheet metal cabinet 1 that matches the fixing pin 35. After the pulley 31 slides into the limiting groove 15, the fixing hole on the mounting cabinet 3 for fixing the pin 35 through is aligned with the screw hole on the fixing hole plate 36, thus smoothly connecting the fixing pin 35 to the fixing hole plate 36. This allows the sheet metal cabinet 1 and the mounting cabinet 3 to be positioned and fixed, preventing them from shaking or moving and colliding during use.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
