DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The embodiment of the present application provides a high-voltage box, which can be horizontally folded into an opening through a horizontal outer flange first, so that when the horizontal outer flange is folded outward, the horizontal outer flange is located on the side of the box with the opening, avoiding the need for the traditional box to expand outward on the basis of the original size, which causes the overall size of the box to expand outward and the space utilization rate to be relatively reduced.

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a high-voltage box, which includes: a box body 1, an opening 101 is opened on one side of the box body 1, horizontal inner flanges 2 are fixed around the opening 101, the four horizontal inner flanges 2 are fixed with vertical outer flanges 3, and the four vertical outer flanges 3 are fixed with horizontal outer flanges 4; projected in a direction perpendicular to the side of the box body 1 with the opening 101, the horizontal outer flange 4 is located inside the side of the box body 1 with the opening 101.

[0033] Specific as Figure 1As shown, the top surface of the box body 1 is provided with an opening 101, and horizontal inner flanges 2 are fixed around the opening 101, and the horizontal inner flange 2 is fixed with a vertical outer flange 3, and the vertical outer flange 3 is fixed with a second horizontal outer flange 4, wherein the inner flange of the horizontal inner flange 2 extends inwardly relative to the opening 101, the outer flange of the vertical outer flange 3 extends vertically relative to the horizontal inner flange 2, and the outer flange of the horizontal outer flange 4 extends outwardly relative to the vertical outer flange 3. Projected along a direction perpendicular to the top surface of the box body 1, the horizontal outer flange 4 is located on the top surface of the box body 1.

[0034] Specifically, the horizontal inner flange 2 is first folded horizontally into the box body 1, so that when the horizontal outer flange 4 is folded outward, the horizontal outer flange 4 is located on the side of the box body 1 with the opening 101, thereby avoiding the need for the traditional box to expand outward on the basis of the original size. This causes the overall size of the box body 1 to expand outward and the space utilization rate to be relatively reduced. The space utilization rate of the box body 1 is greatly improved, and it can better cooperate with the container outside. At the same time, it also ensures that the horizontal outer flange 4 has a suitable width, which is convenient for subsequent installation with the cover plate 5. At the same time, the vertical outer flange 3 is vertically arranged, which can ensure that the horizontal outer flange 4 has a certain structural strength when subjected to a lateral impact.

[0035] In one embodiment, Figure 2 and Figure 3 As shown, the high-voltage box may further include: a cover plate 5, which is detachably fixed to the four horizontal outer flanges 4 and is used to cover the opening 101. Exemplarily, threaded holes are provided around the top surface of the cover plate 5, and fixing bolts are threadedly passed through the threaded holes and are threadedly connected to the horizontal outer flanges 4 to achieve the installation of the cover plate 5.

[0036] In one embodiment, Figure 3 As shown, the cover plate includes a cover and a side cover fixed around the cover, so that the cover plate 5 is concavely arranged, and when the cover plate 5 covers the opening 101, the vertical outer flange 3 and the horizontal outer flange 4 are located inside the cover plate 5. Exemplarily, the cover plate 5 is concavely arranged, and can be pressed on the top surface of the horizontal outer flange 4, and the vertical outer flange 3 and the horizontal outer flange 4 are stored inside the cover plate 5, completing the closing work of the opening 101.

[0037] In one embodiment, Figure 2As shown, when the cover plate 5 covers the opening 101 and is projected in a direction perpendicular to the side of the box body 1 having the opening 101, the cover plate 5 is completely overlapped with the side of the box body 1 having the opening 101. When the cover plate 5 is not closed on the opening 101, there is a certain distance L between the edge of the horizontal outer flange 4 and the edge of the box body 1, that is, a thickness space of the side cover is reserved between the horizontal outer flange 4 and the outer edge of the box body 1. When the cover plate 5 covers the opening 101, the outer surface of the cover plate 5 and the side surface of the box body 1 are located in the same plane, and no excess part exceeds the outside of the box body 1, further ensuring the compact size of the box body 1.

[0038] In one embodiment, Figure 3 As shown, the side wall of the cover plate 5 is provided with at least one notch 501. For example, two notches 501 are provided on the front side of the cover plate 5, and the notches 501 are convenient for the staff to hold the notches 501 and exert force to remove the cover plate 5 from the box body 1.

[0039] In one embodiment, Figure 4 As shown, the high-voltage box may further include: a fixing bracket 6, the fixing bracket 6 is fixed in the box body 1, and the fixing bracket 6 is used to place components. Exemplarily, the components may be fixedly installed on the fixing bracket 6 in advance, and then the fixing bracket 6 is fixed in the box body 1 to complete the installation of the components, thereby avoiding the problem that traditional components are directly installed in the box body 1, which has a small operating space, inconvenient operation, and is prone to collision damage of components.

[0040] In one embodiment, Figure 4 and Figure 5 As shown, the fixing bracket 6 may include: a horizontal plate 601, the horizontal plate 601 is provided with a first mounting hole 602; a vertical plate 603, the vertical plate 603 is fixed to the horizontal plate 601, the vertical plate 603 is provided with a second mounting hole 604, and the vertical plate 603 is provided with a plurality of fixing bolts 605. For example, refer to Figure 4 The horizontal plate 601 has first mounting holes 602 at both ends, and the vertical plate 603 has two second mounting holes 604 near the top. Figure 5, the horizontal plate 601 is conveniently fixed to the inner bottom wall of the box body 1 through the first mounting hole 602, and the vertical plate 603 is conveniently fixed to the inner side wall of the box body 1 through the second mounting hole 604. Among them, the first mounting hole 602 and the second mounting hole 604 can be threaded holes or pin holes. Four fixing bolts 605 are provided throughout the vertical plate 603. The components can be fixed to the vertical plate 603 by the fixing bolts 605 and the external fixing bolts to complete the installation of the components. It is possible to fix the components to the fixing bracket 6 in advance, and then install the fixing bracket 6 in the box body 1, so as to avoid the problem that the traditional components are directly fixed in the box body 1, which may lead to the problem that when the components are fixed in the box body 1, the operating space is small, the operation is inconvenient, and the components are easily damaged by collision.

[0041] In one embodiment, the fixing bracket 6 may also be a U-shaped plate or a mouth-shaped plate, and its components are arranged inside the U-shaped plate or the mouth-shaped plate. The fixing bracket 6 can play a good protective shielding role to prevent the components thereon from affecting the working performance through the thermal coupling effect with other components.

[0042] In one embodiment, the horizontal inner flange 2, the vertical outer flange 3 and the horizontal outer flange 4 are integrally formed. The horizontal inner flange 2, the vertical outer flange 3 and the horizontal outer flange 4 can be integrally formed by stamping.

Exemplarily, the left and right ends of the front side of the box body 1 are fixed with mounting plates 102, and the mounting plates 102 and the front side of the box body 1 are located in the same plane, which can facilitate the subsequent fitting and fixing of the box body 1 with an inner side wall of the container through the mounting plates 102; one or more stop blocks are fixed to the rear side of the box body 1, which can be limited and matched with the stop grooves on the other inner side wall of the container to complete the installation of the box body 1.

[0044] In one embodiment, Figure 1As shown, the same reinforcing plate 103 is fixedly attached between any two adjacent inner side walls of the box body 1, and a through hole is provided in the reinforcing plate 103. Exemplarily, the same reinforcing plate 103 is fixedly attached between the rear inner side wall and the left inner side wall of the box body 1, and the reinforcing plate 103 may be a right-angle plate, one side wall of the reinforcing plate 103 is attached to the rear inner side wall of the box body 1, and the other side wall of the reinforcing plate 103 is attached to the left inner side wall of the box body 1, and the edge of the reinforcing plate 103 is welded and fixed to the box body 1. By providing a through hole in the reinforcing plate 103, if the external welding structure is welded on the reinforcing plate 103, spot welding on the reinforcing plate 103 can be avoided, and the external welding structure can be spot welded at the through hole position of the reinforcing plate 103.
