[0002] The distribution box includes a box body and a set of electrical components. The box body is generally a welded structure, including the front door panel, the rear cover panel (the panel opposite to the front door panel), the left side panel, the right side panel, the bottom panel, and the top panel. Except for the front door panel, any two adjacent panels are connected by welding. The welding process is labor-intensive and inevitably produces harmful gases, which does not meet environmental protection requirements. Assembled distribution box bodies are currently a popular development direction.

[0003] The Chinese utility model patent with authorization announcement number CN214314084U (publication date: 2021.09.28) discloses an assembled distribution box, the left and right side panels of which are provided with folded edges (i.e. fixed plates). During assembly, the folded edges of the left and right side panels are fixedly overlapped, and the folded edges of the left and right side panels are connected and fixed by bolts. Finally, the left and right side panels are fixed as a whole on the rear cover plate (i.e. the bottom plate recorded in the CN214314084U file) by pressing buckles.

[0004] The above distribution box does not require welding, which reduces environmental pollution. However, when assembled at the production site, each bolt needs to be connected separately, which is inefficient. Utility Model Content

[0046] In order to solve the problem of low efficiency caused by the need to separately install bolts during assembly of the assembled distribution box in the prior art, the basic technical concept of the utility model is to provide limit grooves formed by folded edges on the top plate and the bottom plate, and to provide inner folded edges formed by folded edges on the left and right side plates. The inner folded edges and the limit grooves are plugged into and matched with each other to splice the top plate, the bottom plate, the left side plate and the right side plate into a basic "mouth"-shaped frame, and elastic folded edges are provided at the upper and lower ends or the left and right ends of the rear sealing plate. The rear sealing plate is clamped on the top plate and the bottom plate or the left and right side plates through the elastic folded edges to achieve the installation of the rear sealing plate. In this way, a stable box structure (except the front door plate) is formed without using bolts, thereby improving the assembly efficiency.

[0047] The present invention is further described in detail below in conjunction with the embodiments and drawings.

[0048] The specific embodiment of the distribution box body provided by the utility model is as follows:

[0049] The distribution box body provided in this embodiment is as follows Figure 1-Figure 16As shown, the whole is square, including a front door panel 6, a rear cover panel 5, a bottom panel 3, a top panel 4, a left side panel 1 and a right side panel 2, each of which is a sheet metal part. The left side panel 1 and the right side panel 2 have the same shape and structure, and the top panel 4 and the bottom panel 3 have the same shape and structure.

[0050] In order to clearly illustrate the structure of each plate in this embodiment, the direction close to the geometric center of each plate is defined as the inside, and the direction away from the geometric center of each plate is defined as the outside.

[0051] The structure of the left side plate 1 is as follows Figure 2-Figure 4 As shown, the left side panel 1 includes a side panel body and a plurality of folded edges. Specifically, the upper and lower ends of the left side panel 1 are provided with inner folded edges 101 folded inward. Figure 5 As shown, it includes the bottom plate 3 body, the left support fold 304, the right support fold 305, the rear support fold 303 and the front support fold. The left support fold 304, the right support fold 305, the rear support fold 303 and the front support fold are all folded inward. The ends of the left support fold 304 and the right support fold 305 are also provided with a limit fold 301. The limit fold 301 is bent twice to form a limit groove inside. The limit groove has an opening. During installation, it can be installed according to Figure 7 Insert the inner fold 101 of the left side panel 1 into the limiting groove formed by the limiting fold 301 along the opening of the limiting groove. Similarly, the inner fold 101 of the right side panel 2 can also be inserted into the limiting groove formed by the limiting fold 301, as shown in the middle arrow. Figure 8 As shown, by the cooperation of the limiting fold 301 and the inner fold 101, the left side panel 1, the right side panel 2 and the bottom panel 3 are stably spliced. Since the top panel 4 also has the limiting fold 301 and the limiting groove, the top panel 4 can be adjusted to the position corresponding to the limiting groove and the inner fold 101 to achieve the splicing of the top panel 4, the left side panel 1 and the right side panel 2, as shown in FIG. Fig. 9 As shown, a stable "mouth" shaped structure is formed. At the same time, the left supporting edge 304 and the right supporting edge 305 can also play a role in supporting the left side plate 1 and the right side plate 2, making the overall structure more stable.

[0052] The structure of the rear sealing plate 5 is as follows Figure 6 As shown, the upper and lower ends of the rear sealing plate 5 are provided with elastic folding edges 501. Figure 5 As shown, the bottom plate 3 is provided with a mounting groove 302 formed by the support folds, and the inner end surface of the rear support fold 303 forms the groove side wall of the mounting groove 302. Similarly, the top plate 4 is provided with a mounting groove 302 of the same structure. Fig.12In the direction of the arrow shown, the rear sealing plate 5 is clamped on the inner edge of the rear supporting fold 303 of the top plate 4 and the bottom plate 3 by the elastic fold 501. After the rear sealing plate 5 is installed, its lower end is supported on the rear supporting fold 303 of the bottom plate 3, and the front side is abutted against the left side plate 1 and the right side plate 2. The elastic force of the elastic fold 501 provides pressure for the rear sealing plate 5 to press against the left side plate 1 and the right side plate 2, thereby preventing the rear sealing plate 5 from falling off.

[0053] In other embodiments, the mounting groove 302 may also be processed on the rear support flange 303. Figure 5 For example, a mounting groove 302 can be cut downwardly at the middle position of the rear support fold 303, and the elastic fold 501 can be clamped in the mounting groove 302 cut by the rear support fold 303, which can also play a role in limiting the position of the rear sealing plate 5.

[0054] In other embodiments, the left supporting fold 304 and the right supporting fold 305 may not be provided on the bottom plate 3. Figure 5 For example, the vertical edge position below the left supporting fold 304 and the right supporting fold 305 can be directly bent twice to form a limiting fold 301. At this time, the left side panel 1 and the right side panel 2 can be installed on the inner side of the limiting fold 301. Under the support of the rear supporting fold 303 and the front supporting fold, the left side panel 1, the right side panel 2, the bottom panel 3, and the top panel 4 can also form a stable splicing.

[0055] In other embodiments, when installing the rear cover plate 5, the elastic hems 501 may be arranged at the left and right ends of the rear cover plate 5, and the mounting grooves 302 may be arranged correspondingly on the left and right sides of the plate 2. For example, supporting hems are arranged on the left and right sides of the plate 1 and 2, and mounting grooves 302 are processed on the supporting hems. The elastic hems 501 at the left and right ends of the rear cover plate 5 are clamped in the mounting grooves 302 of the left and right sides of the plate 1 and 2. At this time, the front-to-back position of the rear cover plate 5 is limited by the elastic hems 501, and the weight is mainly supported by the left and right sides of the plate 1 and 2.

[0056] In order to determine the position of the left side panel 1 and the right side panel 2 when installing the left side panel 1 and the right side panel 2, a stop structure is also provided in this embodiment. The stop structure can limit the extreme insertion position of the left side panel 1 and the right side panel 2, thereby determining the position of the left side panel 1 and the right side panel 2, and the box body as a whole is more stable. Specifically, in this embodiment, the stop structure is formed by the stop fold 102 provided on the left side panel 1 and the right side panel 2, such as Fig. 9 and Fig.10As shown, after the inner fold 101 of the left side panel 1 and the right side panel 2 is inserted into the limiting groove, the stop fold 102 cooperates with one end of the limiting fold 301 to limit the position of the left side panel 1 and the right side panel 2. Furthermore, the height of the stop fold 102 is equal to the height of the left side panel 1 and the right side panel 2. When installed, the upper and lower ends of the stop fold 102 can be supported and contacted with the bottom panel 3 and the top panel 4 respectively, so that the contact area between the (left / right) side panel and the top panel 4 and the bottom panel 3 can be increased, and the structural strength can be enhanced.

[0057] In other embodiments, the stopper structure may also be provided on the top plate 4 and the bottom plate 3, for example, one end of the limit groove formed by the limit fold 301 may be blocked, and only one end may be open, so that after the inner fold 101 is inserted into the limit groove, one end of the blocked position can also play a role in positioning and limiting. Of course, in other embodiments, the stopper structure may also be provided on the left side plate 1 or the right side plate 2, the top plate 4 and the bottom plate 3, for example, the stopper fold is retained while one end of the limit groove is blocked. Of course, the stopper structure may also be provided on only one of the top plate 4 and the bottom plate 3, so that only one end of the upper and lower parts can stop the left side plate 1 or the right side plate 2, but it can also play a basic limiting role.

[0058] In other embodiments, the height of the stop fold 102 may also be slightly smaller than the height of the left plate 1 and the right plate 2, that is, the upper and lower ends of the stop fold 102 do not contact the top plate 4 and the bottom plate 3, and the stop fold 102 can be ensured to cooperate with the end stop of the limit fold 301.

[0059] In this embodiment, the stopper structure can better limit the position of the left side plate 1 and the right side plate 2, which is convenient for installation. However, in other embodiments, the stopper structure may not be provided. For example, in a larger distribution box, the weight is also heavier. Only the weight of the left side plate 1, the right side plate 2 and the internal electrical components can ensure that the left side plate 1 and the right side plate 2 can be stably placed on the top plate 4 and the bottom plate 3, thereby ensuring the overall stability.

[0060] like Figure 2-Figure 4 and Fig.11 As shown, in order to increase the abutting contact area between the rear cover plate 5 and the left side plate 1 and the right side plate 2, and to improve the strength and stability of the box, the left side plate 1 and the right side plate 2 in this embodiment are provided with a larger width (left and right direction) of the folded edge for contacting and cooperating with the rear cover plate 5, and the folded edge extends to the position of the inner folded edge 101. In order to ensure that the inner folded edge 101 can be smoothly inserted into the limiting groove formed by the limiting folded edge 301, the left side plate 1 and the right side plate 2 in this embodiment are provided with an avoidance notch 103 for avoiding the inner folded edge 101.

[0061] like Figure 12-14As shown, the elastic folding edge 501 in this embodiment includes a protrusion 5011 protruding outward formed by two bends, and the outer surface of the protrusion 5011 is arc-shaped. In this way, when the rear cover plate 5 is installed, the arc-shaped surface can slide along the bottom plate 3 and the top plate 4, and smoothly enter the installation groove 302, which can avoid scratching the top plate 4 and the bottom plate 3. In other embodiments, the protrusion 5011 may not be retained, and the elastic folding edge 501 is bent only once. In this case, the end of the elastic folding edge 501 can be polished to avoid forming a sharp corner at the end.

[0062] In addition, after the elastic folded edge 501 in this embodiment is installed in the installation groove 302, its left and right ends can just support and contact with the top plate 4 and the bottom plate 3, that is, the left and right width of the elastic folded edge 501 is equal to the left and right width of the installation groove 302. This can further improve the overall strength and structural stability of the box. Similarly, for a larger distribution box, the width of the elastic folded edge 501 can also be slightly smaller than the left and right width of the installation groove 302.

[0063] In order to facilitate the smooth insertion of the inner fold 101 into the limiting groove formed by the limiting fold 301, the insertion end of the inner fold 101 in this embodiment (the end that is first inserted into the limiting groove during installation) is provided with an avoidance guide surface 1011, such as Figure 4 As shown, during installation, the avoidance guide surface 1011 can first enter the limiting groove and guide the inner fold 101 to continue to be inserted, which improves efficiency and also facilitates increasing the bending width of the inner fold 101, so that it can have a larger contact area with the limiting groove. Of course, in other embodiments, the avoidance guide surface 1011 may not be provided. In order to ensure that the inner fold 101 can be smoothly inserted into the limiting groove, the bending width of the inner fold 101 can be appropriately reduced.

[0064] In order to facilitate the subsequent installation of electrical components, in this embodiment, installation folds 104 are directly provided on the left side plate 1 and the right side plate 2. After the box body is assembled, it can be directly transferred to the subsequent process of installing electrical components.

[0065] Finally, regarding the installation of the front door panel 6, it can be installed on the left side panel 1 or the right side panel 2 using a hinge consistent with the prior art, or it can be rotatably installed on the front support fold of the top panel 4 and the bottom panel 3 using a hinge pin. Fig.16 After the front door panel 6 is installed, the box body forms a stable hexahedral structure.

[0066] In summary, in this embodiment, when assembling the box body except the front door panel 6, no bolts are needed, the assembly of each part is simple, the operation is convenient, and the assembly efficiency of the distribution box body is improved.
