Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0033] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0034] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0035] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.

[0036] The present utility model provides an electric box housing 100 for installing electrical components.

[0037] To better understand the above technical solution, the following will describe the above technical solution in detail in conjunction with the specification drawings and specific embodiments.

[0038] In an embodiment of the present utility model, as Figures 1 to 8 shown, the electric box housing 100 includes a side plate assembly 10 and a bottom plate 20. Among them, the side plate assembly 10 is formed by bending and connecting the head and tail of the same flat plate to form four side plates; the bottom plate 20 is provided at the bottom of the side plate assembly 10 and covers the bottom opening of the side plate assembly 10; the four-week bottom of the side plate assembly 10 and the four-week outside of the bottom plate 20 are wound to form an annular first crimping edge 30 and achieve a fixed connection.

[0039] It can be understood that the side plate assembly 10 of the present utility model is an integrally formed structure, which can reduce the welding process, thereby reducing labor intensity and improving production efficiency. That is, in the prior art, four flat plates are used to form the side plate assembly 10, and four positions need to be welded; two L-shaped plates are used to form the side plate assembly 10, and two positions need to be welded. However, in the present utility model, the side plate assembly 10 is formed by stamping and bending a single flat plate, and only the head and tail connection positions need to be connected. This position can be fixed by welding, bonding, or clamping. Since the number of connection positions is reduced, the risk of insecure connection can be reduced. At the same time, the side plate assembly 10 and the bottom plate 20 also adopt a new connection method to avoid problems such as welding detachment and false welding, so as to improve the sealing performance of the electric box housing 100 and improve the overall structural strength. Specifically, the four-week bottom of the side plate assembly 10 and the four-week outside of the bottom plate 20 are wound to form an annular first crimping edge 30 and achieve a fixed connection. The winding forming is to overlap the plates at the connection positions of the side plate assembly 10 and the bottom plate 20, and the overlapping plates are clamped by a crimping machine and wound in the same direction, thereby realizing the connection and fixation of the side plate assembly 10 and the bottom plate 20. This process is realized by a crimping machine, which further reduces the labor intensity of employees and improves production efficiency. The electric box housing 100 with a crimping edge has good sealing performance, and the arc-shaped crimping edge can also prevent construction workers from being scratched. At the same time, the rounded corner reduces the difficulty of wall cutting and opening compared with a right angle, which is convenient for construction.

[0040] The technical solution of the present utility model includes a side plate assembly 10 and a bottom plate 20. The side plate assembly 10 is formed by bending and connecting the head and tail of the same flat plate to form four side plates. The periphery of the bottom of the side plate assembly 10 and the periphery of the outside of the bottom plate 20 are wound to form an annular first crimp 30 and achieve a fixed connection. Due to the technical means of integrally forming the side plate assembly 10 and forming the first crimp 30 by winding the side plate assembly 10 and the bottom plate 20, the technical problems of connection hidden dangers, high labor intensity and low production efficiency existing in the prior art are effectively solved, and the technical effects of firm structure, good sealing performance, reduced labor intensity and improved production efficiency are realized.

[0041] In an embodiment of the present utility model, as Figure 1 and Figure 2 shown, the first crimp 30 is an annular inward crimp, and the first crimp 30 is located at the bottom of the bottom plate 20. By adopting the annular inward crimp, the outer surface can be made flat, and the first crimp 30 located at the bottom can also play a supporting role.

[0042] In another embodiment of the present utility model, as Figures 3 to 8 shown, the first crimp 30 is an annular outward crimp, and the first crimp 30 is located on the outside of the side plate assembly 10. By adopting the annular outward crimp, that is, an annular first crimp 30 is formed around the bottom of the electric box body 100, this method can reduce the overall height of the electric box body 100 and make the bottom plate 20 fit the installation surface. Each of the annular inward crimp and the annular outward crimp has its own advantages and can be selected according to actual needs.

[0043] In an embodiment of the present utility model, the adjacent side plates are in an arc transition. During the bending and forming process of the side plate assembly 10, the transition connection between the adjacent side plates is in an arc shape. The arc transition has the advantages of reducing stress concentration and avoiding scratches caused by sharpness.

[0044] In an embodiment of the present utility model, the head and tail of the side plate assembly 10 are fixed by welding connection. The side plate assembly 10 of the present utility model is connected and fixed by welding, which has good sealing performance and improves the waterproof and dustproof effect.

[0045] In an embodiment of the present utility model, as Figures 1 to 8 shown, the top of the side plate assembly 10 is wound to form an annular second crimp 11. The function of the second crimp 11 is the same as that of the first crimp 30. The second crimp 11 has the advantage of improving the structural strength. At the same time, the arc-shaped crimp can also avoid scratches.

[0046] In an embodiment of the present utility model, the second crimp 11 is an annular inward crimp or an annular outward crimp. Each of the annular inward crimp and the annular outward crimp has its own advantages and can be selected according to actual needs, such as Figure 1 、 Figure 2 、Figure 7 and Figure 8 As shown, when the second curled edge 11 adopts an annular inward curled edge, the overall external installation space can be reduced. For example Figures 3 to 6 As shown, when the second curled edge 11 adopts an annular outward curled edge, it is more convenient to clean the sundries or dust inside the electrical box body 100. At the same time, in the present utility model, the first curled edge 30 and the second curled edge 11 can adopt the same curling method or different curling methods, which are not limited herein.

[0047] In an embodiment of the present utility model, as Figures 5 to 8 shown, a step 12 for cooperating with the electrical box cover is formed at the top of the side plate assembly 10. The step 12 is integrally formed, and the cooperation of the step 12 is more conducive to positioning and assembly.

[0048] In an embodiment of the present utility model, as Figures 1 to 8 shown, the side plate assembly 10 is provided with a plurality of through holes for wiring. The opening positions and the number of the through holes can be adjusted according to actual needs, which are not limited herein.

[0049] The present utility model also proposes an electrical box (not shown in the figure), which includes an electrical box body 100, an electrical box cover, and electrical components. The specific structure of the electrical box body 100 refers to the above embodiment. Since this electrical box adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one. Among them, the box cover is assembled to the top opening of the electrical box body 100; the electrical components are installed inside the electrical box body 100.

[0050] The above are only optional embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
