[0046] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0047] like Figure 1-2 As shown, the corner piece 10 is constructed as a cube, including a bottom plate 11 and a top plate 12 arranged oppositely, an outer end plate 13 and an inner end plate 14 arranged oppositely, and an outer side plate 15 and an inner side plate 16 arranged oppositely. Among them, transition surfaces 20 are formed between the inner surfaces of the outer end plate 13 and the outer side plate 15, the inner surfaces of the outer end plate 13 and the inner side plate 16, the inner surfaces of the inner end plate 14 and the outer side plate 15, and the inner surfaces of the inner end plate 14 and the inner side plate 16. The transition surface 20 extends from the inner surface of the bottom plate 11 to the inner surface of the top plate 12, and the transition surface 20 has a fillet with a radius of not less than 15 mm in a cross section parallel to the surface of the top plate 12. In addition, the cross sections of multiple transition surfaces 20 have fillets with the same radius, or the cross sections of multiple transition surfaces 20 have fillets with different radii.

[0048] The utility model adds a plurality of transition surfaces 20 extending from the bottom plate 11 to the top plate 12 between the inner surfaces of the outer end plate 13, the inner end plate 14, the outer side plate 15 and the inner side plate 16 of the corner piece 10, and the cross section of the transition surface 20 has a rounded corner with a radius of not less than 15 mm, so as to disperse and absorb stress and improve the strength of the corner piece 10 to meet the working conditions of lifting, stacking, bolting and the like of overweight containers. The radius of the rounded corners of the multiple cross sections can be the same or different to meet the needs of different situations.

[0049] Specifically, Figure 1 As shown, the corner piece 10 can be formed by casting, for example, and the size of the corner piece 10 along the width direction D3 is 161.5mm-162.5mm, and the width direction D3 is perpendicular to the outer side plate 15. The size of the corner piece 10 along the length direction D2 is 177mm-178mm, and the length direction D2 is perpendicular to the outer end plate 13. Figure 2 As shown, the dimension of the corner piece 10 along the height direction D1 is 118 mm-119 mm, and the height direction D1 is perpendicular to the top plate 12.

Among them, the outer end plate 13 is provided with an end hole 18, the outer side plate 15 is provided with a side hole 19, and the inner end plate 14 and the inner side plate 16 are not provided with a through hole. Transition surfaces 20 are formed between the inner surfaces of the outer end plate 13 and the outer side plate 15, the inner surfaces of the outer end plate 13 and the inner side plate 16, the inner surfaces of the inner end plate 14 and the outer side plate 15, and the inner surfaces of the inner end plate 14 and the inner side plate 16. The transition surface 20 extends from the inner surface of the bottom plate 11 to the inner surface of the top plate 12, that is, it passes through the inside of the corner piece 10 in the height direction D1. The transition surface 20 has a fillet with a radius of not less than 15 mm in a cross section parallel to the surface of the top plate 12, that is, a cross section perpendicular to the height direction D1. The cross sections of the transition surface 20 formed between multiple different inner surfaces can have fillets with the same radius, or multiple cross sections can have fillets with different radii.

[0051] For example, see Figure 1 The cross section of the transition surface 20 formed between the outer end plate 13 and the inner surface of the outer side plate 15 may have a fillet with a radius of 25 mm, the cross section of the transition surface 20 formed between the inner end plate 14 and the inner surface of the outer side plate 15 may have a fillet with a radius of 20 mm, and the cross section of the transition surface 20 formed between the inner surface of the outer end plate 13 and the inner side plate 16 and between the inner end plate 14 and the inner side plate 16 may have a fillet with a radius of 15 mm.

There is a fillet with a radius of 5mm-6.5mm between the long side and the arc-shaped side. As shown Figure 2 and Figure 3 As shown, the bottom hole 17 is constructed with a 45-degree inner chamfer with a width of 5mm-6.5mm on one side of the outer surface close to the bottom plate 11, which is used to improve the safety of the corner piece 10 and facilitate processing and assembly.

[0054] like Figure 1 As shown, specifically, the thickness of the outer plate 15 is 19.5 mm-21.5 mm. By ensuring the wall thickness of the outer plate 15, the strength of the corner piece 10 can be further increased to ensure the lifting, stacking, bolting and other working conditions of the overweight equipment box. Figure 2As shown, the outer plate 15 is provided with a side hole 19, which is a waist-shaped hole, and the long axis of the side hole 19 is perpendicular to the bottom plate 11, so as to better withstand stress. Specifically, the length of the side hole 19 is, for example, 79.5 mm-81 mm, the width of the side hole 19 is, for example, 51 mm-52.5 mm, the distance between the long axis of the side hole 19 and the outer surface of the outer end plate 13 in the length direction D2 is, for example, 100 mm-101.5 mm, and the distance between the end of the side hole 19 close to the bottom plate 11 and the outer surface of the bottom plate 11 in the height direction D1 is, for example, 27.5 mm-29.5 mm.

[0055] like Figure 1 As shown, specifically, the thickness of the outer end plate 13 is 19.5 mm-21.5 mm. By ensuring the wall thickness of the outer side plate 15, the strength of the corner piece 10 can be further increased to ensure the lifting, stacking, bolting and other working conditions of the overweight equipment box. Figure 3 and Figure 4 As shown, the outer end plate 13 is provided with an end hole 18, which is constructed as a shield-shaped hole or a waist-shaped hole, and the long axis of the end hole 18 is perpendicular to the bottom plate 11, so as to better withstand stress.

[0056] The corner fittings 10 are divided into top corner fittings 10 and bottom corner fittings 10, wherein Figure 3 As shown, the end hole 18 of the top corner piece 10 is configured as a shield-shaped hole.
