[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] The specific technical solution of this utility model is as follows:

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a modular low-voltage distribution cabinet includes a cabinet body, which includes a bottom plate 1, a top plate 2, and side plate assemblies.

[0022] The side plate assembly includes four columns 3 and four side plates 4. The four columns 3 are arranged in a rectangle. Each column 3 has two mutually perpendicular side plate connecting surfaces 31. The side plate connecting surfaces 31 are provided with a plurality of side plate connecting threaded holes arranged vertically at equal intervals. The side plates 4 are disposed between two adjacent columns 3, and the side edges of the side plates 4 are vertically bent to form a fixed edge 41 for fitting with the side plate connecting surfaces 31. The fixed edge 41 is provided with side plate bolt holes 42 corresponding to the side plate connecting threaded holes. Side plate fastening bolts 5 that are threadedly engaged with the side plate connecting threaded holes are inserted into the side plate bolt holes 42.

[0023] The bottom end of the column 3 is provided with a base plate connector, the base plate connector is provided with a base plate connection threaded hole, the base plate 1 is provided with a base plate bolt hole corresponding to the base plate connection threaded hole, and a base plate fastening bolt that is threadedly engaged with the base plate connection threaded hole passes through the base plate bolt hole.

[0024] The top of the column 3 is provided with a top plate connector 32, the top plate connector 32 is provided with a top plate connecting threaded hole 33, the top plate 2 is provided with a top plate bolt hole corresponding to the top plate connecting threaded hole 33, and a top plate fastening bolt that is threaded to the top plate connecting threaded hole 33 passes through the top plate bolt hole.

[0025] The above-mentioned method is adopted: When assembling the cabinet, firstly, pass the bottom plate fastening bolts through the bottom plate bolt holes from below the bottom plate 1, so that the bottom plate fastening bolts engage with the bottom plate connecting threaded holes of the bottom plate connector and tighten them, so that the uprights 3 are fastened to the bottom plate 1; then, place the side plate 4 between two adjacent uprights 3, so that the fixing edge 41 of the side plate 4 is in contact with the side plate connecting surface 31 of the corresponding upright 3, and then pass the side plate fastening bolts 5 through the side plate bolt holes of the fixing edge 41, so that the side plate fastening bolts 5 engage with the side plate connecting threaded holes of the side plate connecting surface 31 and tighten them, so that the side plate 4 is fastened to the uprights 3; finally, place the top plate 2 on top of the four uprights 3, and then pass the top plate fastening bolts through the top plate bolt holes from above the top plate 2, so that the top plate fastening bolts engage with the top plate connecting threaded holes 33 of the top plate connector 32 and tighten them, so that the top plate 2 is fastened to the uprights 3, thus completing the assembly of the cabinet.

[0026] Furthermore, the side plate connecting surface 31 is provided with a slot 34, and the side of the fixed edge 41 away from the side plate 4 is vertically bent to form a snap-fit ​​edge 43 for engaging with the slot 34.

[0027] The above solution is adopted: when assembling the side plate 4 and the column 3, the snap-fit ​​edge 43 of the side plate 4 is first snapped into the snap-fit ​​groove 34 of the side plate connecting surface 31 to achieve the pre-positioning between the side plate 4 and the column 3.

[0028] Furthermore, the bottom of the base plate 1 is provided with a groove for accommodating the head of the base plate fastening bolt, and the top of the top plate 2 is provided with a groove for accommodating the head of the top plate fastening bolt.

[0029] The above solution aims to prevent the heads of the fastening bolts from protruding from the top and bottom surfaces of the cabinet, so that the top and bottom surfaces of the cabinet are flat and aesthetically pleasing.

[0030] Furthermore, a sealing strip 6 is affixed to the outer side of the space between the column 3 and the side plate 4.

[0031] The above solution is adopted to improve the sealing of the joint between the upright 3 and the side panel 4, and to reduce the amount of external dust entering the cabinet through the joint.

[0032] Furthermore, two lifting lugs 7 are symmetrically provided on the top of the top plate 2.

[0033] The above solution is adopted: Lifting lug 7 is used to connect to the lifting equipment so that the cabinet can be lifted as a whole.

[0034] Furthermore, the four side panels 4 are respectively the front side panel, the rear side panel, the left side panel and the right side panel. The front side panel is provided with a door panel mounting opening, and a cabinet door 8 is installed in the door panel mounting opening by means of a hinge.
