[0050] At present, in the application of medium-voltage distribution cabinets, the cabinet frames of the medium-voltage distribution cabinets are usually prefabricated. In this application form, the prefabricated cabinet frames will occupy a large space and are not convenient for transportation and manual handling.

[0051] Based on this, some post-assembly application forms have been proposed in the market; for example, the cabinet frame is split into separate column structures, and the entire cabinet frame is assembled by installing and connecting the column structures. However, although this application form can reduce the space occupied during transportation, the column structures are not connected to each other during transportation, and the column structures are in a relatively scattered state. There are a large number of components, which is prone to the problem of missing components, and the assembly operation is cumbersome, which still has many inconveniences in application.

[0052] In response to the above technical problems, the present embodiment mainly provides a cabinet-type frame structure and a power distribution cabinet, which can improve the convenience of the power distribution cabinet during transportation and can be simpler and more convenient to use.

[0053] like Figure 1-6 As shown in , a cabinet-type frame structure provided according to some embodiments of the present application includes a first frame 1, a plurality of columns 2 and a second frame 3. When assembled, the plurality of columns 2 are arranged upright, and the first frame 1 and the second frame 3 are respectively arranged at the upper and lower ends of the columns 2 to form the entire frame structure.

[0054] In some embodiments, the number of the columns 2 is adapted to the number of sides of the entire frame structure; for example, when set as a rectangular frame structure, the shapes of the first frame 1 and the second frame 3 are adapted and rectangular, and at this time, four columns 2 are provided and are located at the corner ends of the first frame 1 and the second frame 3.

[0055] In some embodiments, a plurality of accommodating cavities 11 are provided on the first frame 1, and the accommodating cavities 11 can be used to store and place the columns 2; for example, when the columns 2 are stored in the accommodating cavities 11, the entire frame structure is in a stacked state, such as Figure 3 When the column 2 is erected in the accommodating cavity 11, the frame of the entire frame structure is in an expanded state, as shown in FIG. Figure 1 shown.

[0056] In some embodiments, a first disassembly and assembly mechanism 4 is provided between the second frame 3 and the column 2. When the first disassembly and assembly mechanism 4 is in a connected state, the frame expanded state is formed between the first frame 1, the column 2 and the second frame 3.

[0057] In some embodiments, a second disassembly and assembly mechanism 5 is further provided between the second frame 3 and the column 2. When the second disassembly and assembly mechanism 5 is in a connected state, the first disassembly and assembly mechanism 4 is in a disassembled state. At this time, the column 2 is accommodated in the accommodating cavity 11, and the frame overlapping state is formed between the first frame 1 and the second frame 3.

[0058] By setting the accommodating cavity 11, it is convenient to store and place the column 2 on the first frame 1, and by controlling the setting state of the column 2 in the accommodating cavity 11, the entire frame structure can have a frame expansion state and a frame folding state; and by controlling the connection state of the first disassembly and assembly mechanism 4 and the second disassembly and assembly mechanism 5, the entire frame structure can be switched between the frame expansion state and the frame folding state, which is simpler and more convenient to use; and in the frame folding state, the column 2 is stored in the first frame 1 and connected to the second frame 3, which has better integrity and can facilitate improving the convenience of the entire frame during transportation.

[0059] As an application example, a third disassembly and assembly mechanism 6 is provided between the first frame 1 and the column 2 , and the third disassembly and assembly mechanism 6 is used to fix the column 2 after the state conversion.

[0060] In some embodiments, the third disassembly and assembly mechanism 6 is connected to the end of the column 2 so that the movement of the column 2 in the accommodating cavity 11 is in the form of a swinging motion.

[0061] By setting the third disassembly and assembly mechanism 6, the column 2 after the state conversion can be installed and fixed, so as to maintain the state of the entire frame structure after the state conversion, which can be more convenient to use.

[0062] As an application example, the third disassembly and assembly mechanism 6 includes an anti-rotation rod 61 , and the first frame 1 and the column 2 are provided with an anti-rotation hole 62 matched with the anti-rotation rod 6 .

[0063] In some embodiments, the cross-sectional shape of the anti-rotation plug rod 61 is used as a basic shape, and the shape formed by rotating the basic shape 90° from the center is a combined shape. At this time, only the anti-rotation socket 62 on the first frame 1 can be set in a basic shape, and the anti-rotation socket 62 on the column 2 can be set in a combined shape; or, only the anti-rotation socket 62 on the first frame 1 can be set in a combined shape, and the anti-rotation socket 62 on the column 2 can be set in a basic shape; or, the anti-rotation sockets 62 on both the first frame 1 and the column 2 can be set in a combined shape.

[0064] In some embodiments, the basic shape may be set to be a rectangle, and the combined shape is a cross formed by combining two rectangles, such as Figure 4 shown.

[0065] By plugging and fitting the anti-rotation plug rod 61 and the anti-rotation plug hole 62, the current state of the column 2 can be fixed, and the plug-in fitting method is simpler and more convenient in operation.

[0066] As an application example, the anti-rotation insertion rod 61 includes an insertion rod section 611 and a gripping portion 612 , and a stopper portion 613 is provided between the insertion rod section 611 and the gripping portion 612 .

[0067] The provided insertion rod segment 611 can be used for plugging and mating with the anti-rotation socket 62; the provided gripping portion 612 can facilitate handheld operation by the operator; the provided stop portion 613 can limit the insertion depth of the insertion rod segment 611 in the anti-rotation socket 62, thereby facilitating further improving the convenience of operation.

[0068] As an application example, an elastic anti-slip mechanism 7 is provided on the contact surface between the anti-rotation plug rod 61 and the anti-rotation plug hole 62 .

[0069] In some embodiments, the elastic anti-slip mechanism 7 includes a marble 71, a spring 72 for providing elastic force to the marble 71, and a groove matching the marble 71; for example, the marble 71 can be embedded in the anti-rotation rod 61, and the spring 72 can be connected and arranged between the marble 71 and the anti-rotation rod 61, as shown in FIG. Figure 5 , 6 As shown; then a groove matching the marble 71 is set in the anti-rotation socket 62, so that during the plug-in operation, when the anti-rotation rod 61 is inserted into the preset position, the marble 71 will extend into the corresponding groove, thereby forming a snap-on limit.

[0070] In some embodiments, the marble 71 and the spring 72 may also be disposed in the anti-rotation socket 62 , and a groove matching the marble 71 may be disposed on the surface of the anti-rotation rod 61 .

[0071] By providing the elastic anti-slip mechanism 7, an elastic snap fit can be formed between the anti-rotation rod 61 and the anti-rotation socket 62 to prevent the anti-rotation rod 61 from accidentally slipping out of the anti-rotation socket 62, making the use more reliable.

[0072] As an application example, the accommodating cavity 11 and the column 2 may be arranged in a one-to-one correspondence.

[0073] In some embodiments, a rectangular frame structure is used as an example. In this case, the accommodating cavity 11 can be set on each cross bar 12 of the first frame 1, and the columns 2 are movably arranged in the accommodating cavity 11 one by one. In this case, the shape enclosed by the accommodating cavities 11 is the same as the shape of the first frame 1, such as Figure 1 shown.

[0074] In some embodiments, the width of the pillar 2 matches the width of the accommodating cavity 11 .

[0075] As one application example, the accommodating cavities 11 can also be configured to be spaced apart from each other, and the columns 2 are respectively disposed at both ends of each accommodating cavity 11 , and the columns 2 located at both ends of the accommodating cavity 11 are housed in the same accommodating cavity 11 .

[0076] In some embodiments, a rectangular frame structure is also used as an example. In this case, two accommodating cavities 11 are provided and are respectively provided on two oppositely arranged cross bars 12 of the first frame 1 ; and the columns 2 located at both ends of the accommodating cavity 11 are simultaneously accommodated in the same accommodating cavity 11 .

[0077] In some embodiments, the sum of the widths of the two columns 2 matches the width of the accommodating cavity 11 .

[0078] By designing the corresponding relationship between the column 2 and the accommodating cavity 11 , different application solutions can be provided to achieve the storage of the column 2 in the accommodating cavity 11 .

[0079] As one application example, the first disassembly and assembly mechanism 4 includes a first protrusion 41, a first groove 42 and a plurality of fasteners 43; wherein, the first protrusion 41 is provided with a plurality of protrusions, and is respectively arranged on the second frame 3 corresponding to the position of the column 2 in the frame expansion state of the frame structure, and is arranged toward the first frame 1; the first groove 42 is arranged at the top end of the column 2, and during installation, the first protrusion 41 is inserted into the first groove 42, thereby forming a connection relationship.

[0080] In some embodiments, mounting holes 44 are provided on the first protrusion 41 and the first groove 42 , and the fastener 43 is inserted into the mounting holes 44 to achieve a reliable connection between the first protrusion 41 and the first groove 42 .

[0081] As another application example, the first disassembly and assembly mechanism 4 can also be configured to include a plug-in groove. In this case, the plug-in groove corresponds to the position of the column 2 in the unfolded state of the frame structure, and is respectively arranged on the second frame 3 and arranged toward the first frame 1; during installation, the top end of the column 2 is inserted into the plug-in groove to form a connection relationship.

[0082] In some embodiments, the mounting holes 44 are provided on both the second frame 3 and the column 2 , and the fasteners 43 are passed through the mounting holes 44 to achieve connection.

[0083] By setting up the first disassembly and assembly mechanism 4, it is easy to realize the detachable installation connection between the column 2 and the second frame 3 when the frame is unfolded, and the installation connection and disassembly operations can be simpler and more convenient.

[0084] As one application example, the second disassembly and assembly mechanism 5 includes a second protrusion 51 and a second groove; wherein the second protrusion 51 is arranged on the column 2 and is located on the side of the column 2 facing upward when the column 2 is in the storage state; the second groove is arranged in the second frame 3 corresponding to the setting position of the second protrusion 51; when folded, the second protrusion 51 is inserted into the second groove, thereby forming a connection relationship, such as Figure 3 shown.

[0085] In some embodiments, the mounting hole 44 is also provided on the second protrusion 51 and the second groove, and the fastener 43 is passed through the mounting hole 44 to achieve a reliable connection between the second protrusion 51 and the second groove; moreover, due to the different corresponding application states, the second disassembly and assembly mechanism 5 can share the same set of fasteners 43 with the first disassembly and assembly mechanism 4, so the frame structure in this embodiment will not have scattered parts in the transportation state, has higher integrity, and is convenient for transportation and handling.

[0086] By setting up the second disassembly and assembly mechanism 5, it is possible to facilitate the detachable installation connection between the column 2 and the second frame 3 in the frame overlapping state, further improving the convenience of installation connection and disassembly operation.

[0087] As an application example, a lifting handle 13 is provided on the first frame 1 and / or the second frame 3 .

[0088] In some embodiments, the lifting handle 13 on the first frame 1 is arranged on the outer side of the first frame 1 .

[0089] In some embodiments, the lifting handle 13 on the second frame 3 is arranged on the top end surface of the second frame 3 .
