Abstract
Description
Technical Field
[0001] The utility model relates to the field of electric control boxes, in particular to a self-sealing corner structure and an electric control box comprising the structure. Background Art
[0002] The electric control box is one of the commonly used industrial parts, usually welded with galvanized sheets. In order to obtain a box with a smooth outer surface and good overall aesthetics, the welded box needs to be polished at the welding point, but this will damage the galvanized layer and must be sprayed to prevent rust, which greatly increases the production cost and labor cost of the electric control box; and using stainless steel plates instead of galvanized plates to make the electric control box, not only does it have a high material cost, but it also greatly increases the difficulty of cutting and bending. In addition, the assembly screws between the various plates of the electric control box are exposed on the shell, which further affects the overall aesthetics. Utility Model Content
[0003] Purpose of the utility model: The purpose of the utility model is to provide a self-sealing corner structure and an electric control box including the structure, which solves the problems existing in the existing electric control boxes.
[0004] Technical solution: The utility model provides a self-sealing corner structure, including a first bend and a second bend extending from the adjacent edges of the main body, the first bend includes a first folded edge and a second folded edge arranged vertically, and the first folded edge and the second folded edge are respectively provided with a first notch and a second notch at the end close to the second bend; the second bend includes a third folded edge, a fourth folded edge, and a fifth folded edge, the fourth folded edge is perpendicular to the third folded edge and is located at the first notch position of the first folded edge, and the fifth folded edge is perpendicular to the third folded edge and is located at the second notch position of the second folded edge. Compared with the original structure that seals the corners through welding technology, the design of the self-sealing corner structure not only makes the folded plate structure more solid and more beautiful in appearance, but also eliminates the processes of grinding, spraying and plating, thereby saving production costs and labor costs, and has wide applicability.
[0005] Furthermore, the first notch is in the shape of a right-angled trapezoid, the fourth fold is in the shape of a right-angled trapezoid, and a gap is left between the first notch and the fourth fold, and the gap range is 0.15mm~0.3mm. The first notch is in the shape of a right-angled trapezoid, and the bevel is set to improve the structural strength of the first bend, and effectively avoid deformation of the first bend due to stress. In addition, the setting of the gap ensures the bending margin and improves the aesthetics of the fold.
[0006] Furthermore, the second notch is in a rectangular shape, the fifth fold is in a rectangular shape, and there is a gap between the second notch and the fifth fold, and the gap ranges from 0.15 mm to 0.3 mm, thereby ensuring the bending margin and improving the overall aesthetics.
[0007] Furthermore, an electric control box includes a box body, a top plate, a bottom plate, and a door plate, wherein the box body, the top plate, the bottom plate, and the door plate all adopt the self-sealing angle structure. Compared with the original electric control box, the welding, grinding, and spraying and repainting processes are saved, thereby greatly reducing the cost.
[0008] Furthermore, the box body includes a back panel, a first side panel, and a second side panel. The first side panel and the second side panel are arranged side by side on both sides of the back panel and are arranged perpendicular to the back panel. The self-sealing corner structure is located at the corners of the first side panel and the second side panel away from the back panel.
[0009] Furthermore, the top plate is provided with a first limiting fold and a second limiting fold, and the first limiting fold and the second limiting fold are respectively vertically arranged on the side of the first fold and the fifth fold. The arrangement of the first limiting fold and the second limiting fold enables the top plate to play a better role in limiting the position when it is installed on the box body. In addition, the top plate can be connected by rivets or bolts through the holes on the first limiting fold and the second limiting fold and the holes on the box body back plate, the first side plate, and the second side plate fold, so that there is no assembly fastener on the outside of the electric control box, which greatly improves the overall aesthetics.
[0010] Furthermore, the bottom plate is provided with a third limiting fold and a fourth limiting fold, and the third limiting fold and the fourth limiting fold are respectively vertically arranged on the side of the first fold and the fifth fold. The setting of the third limiting fold and the fourth limiting fold not only limits the position of the bottom plate installed on the box body, but also is used for internal connection, thereby improving the overall aesthetics of the electric control box.
[0011] It can be seen from the above technical scheme that the utility model has the following beneficial effects: 1) A self-sealing angle structure is provided to replace the original welding connection, which not only saves the welding, grinding and spraying processes, thereby reducing costs and improving work efficiency, but also greatly improves the overall aesthetics of the electric control box; 2) Folding edges are provided on the top plate and the bottom plate of the electric control box, which are connected and fixed to the box body by internal screws or rivets. The entire electric control box has no exposed fasteners, thereby greatly improving the aesthetics of the entire electric control box; 3) The structure is simple, easy to install, and has wide applicability.
