The end frame 11 includes an upper end beam 111, a lower end beam 113 and two parallel corner posts 112, wherein the upper end beam 111, the lower end beam 113 and the two corner posts 112 enclose a square frame structure by a top corner piece 115 and a bottom corner piece 114. The end frame 11 is provided with a plurality of inclined support plates 15, and the inclined support plates 15 are used for connecting the connecting ring 3 at the front end of the tank body 2. The inclined support plates 15 are located in the inner frame area of the end frame 11, i.e. not beyond the range of each frame of the end frame 11. The inclined support plate 15 is connected between the end lower beam 113, the end upper beam 111 and each corner post.

The inclined support plate 15 is a plate-shaped structure, and may be a bent plate, and the bent direction of the bent plate faces the top corner piece 115 or the bottom corner piece 114 of the end frame 11. The inclined support plate 15 has an outer edge 151 facing one corner of the end frame 11 and an inner edge 152 facing the center of the end frame 11 (intersection point of diagonal lines of the end frame 11), and a circular arc 153 is provided at the joint of the outer edge 151 and the end frame 11, and the angle of the circular arc 153 is greater than or equal to 90 degrees to reduce the local stress at the joint. The arc 153 is concave toward the bottom corner member 114 of the end frame 11, i.e. the center of the arc 153 is located at the side of the outer edge 151 facing the top corner member 115, so as to increase the area of the joint between the inclined support plate 15 and the end frame 11 as much as possible, thereby increasing the connection strength and reducing the stress. The junction of inner edge 152 and end frame 11 may be at a right angle. It is understood that in other embodiments, the connection between the inner edge 152 and the end frame 11 may be configured as an arc (as shown in fig. 6).

Because the inclined supporting plate is plate-shaped structure, for adopting square pipe as the inclined supporting in the traditional art, the inclined supporting plate of this scheme is little as the shared space of a plate-shaped structure self for can reserve more spaces in the end frame and install other parts, also simplify the structure of end frame simultaneously, and for square pipe, welding process's complexity has also reduced. In addition, the connecting part of the inclined supporting plate and the end frame is provided with an arc, so that the stress generated at the connecting part of the inclined supporting plate and the end frame can be reduced, and the connecting strength of the inclined supporting plate and the end frame is enhanced.

Correspondingly, the minimum distance S2 from the inner edge 152 to the connecting ring 3 is also not less than 20 mm.

Further, referring to fig. 5, which is a schematic structural view of the frame of the tank container of the present invention, the plurality of inclined support plates 15 of the end frame 11 are located at the inner side of the end frame 11 near the transverse center plane P of the frame 1, so that sufficient space is left in the frame of the end frame 11 (i.e., the space defined by the widths of the two corner posts, the end upper beam and the end lower beam) for installing accessories, such as ladders, valves, etc. Specifically, the inclined support plates 15 and the inner end surface of the end frame 11 are located on the same plane, wherein the inner end surface of the end frame 11 is a plane where the inner end surfaces of the two corner posts 112, the end upper beam 111 and the end lower beam 112 facing the transverse center plane P of the frame 1 are located. Inclined support plate 15 sets up in one side that end frame 11 is close to frame 1 horizontal central plane P, and lies in the coplanar with end frame 11's interior terminal surface, can leave more space installation annex on the one hand, and on the other hand guarantees that each inclined support plate 15 can be connected at the coplanar with clamping ring 3, guarantees the fastness and the reliability of connecting.

Further, as shown in fig. 2, a front end connecting plate 16 is disposed at the middle position of each of the end upper beam 111, the end lower beam 113 and the corner post 112 of the end frame 11, and each front end connecting plate 16 is connected with each inclined supporting plate 15 in sequence to form a ring shape. When the outer diameter of the can body 2 is small, the coupling ring 3 is coupled to the inclined support plate 15 and the front end coupling plate 16. In another embodiment, when the outer diameter of the can body 2 is large, the connecting ring 3 is connected with the inclined support plate 15 and the corner post 113, in which case the front end connecting plate is not necessary. The front section connecting plate 16 extends from the plane of the inner end surface of the end frame 11 to the inside of the end frame 11, and is located on the same plane as the inner end surface of the end frame 11. Thus, the front end connecting plates 16 and the inclined support plates 15 are located on the same plane.

In addition, the distance between the inner edge and the outer edge of the inclined support plate 15 on the end frame 12 and the connection ring 3 is also similar to the distance between the inclined support plate 15 on the end frame 11, specifically, as shown in fig. 6, which is a schematic side view of the rear side of the tank container of the present invention, the shape of the outer edge 151 of the inclined support plate 15 of the end frame 12 is set according to the thermal insulation profile of the tank container, and the minimum distance S3 between the outer edge 151 and the connection ring 3 is not less than 20mm, so that the connection ring 3 is connected with the inclined support plate with a large enough area, and the firmness and reliability of the connection between the connection ring 3 and the inclined support plate 15 are ensured. Correspondingly, the minimum distance S4 from the inner edge 152 to the connecting ring 3 is also not less than 20 mm.

The structure of the inclined support plate 15 on the end frame 12 is different from that of the inclined support plate 15 on the end frame 11 mainly in that, as shown in fig. 3, two inclined support plates 15 connected with the end lower beam 123 of the end frame 12 are spaced from each other to form a gap 124, the gap 124 is just above the bottom discharge gap 125 of the end frame 12, and the distance L1 between the two inclined support plates 15 is 500-900 mm. The two inclined support plates 15 are disconnected from each other, so that the installation space of the rear end frame valve box is enlarged, the valve box is suitable for installation of a larger and wider valve box, and the disconnected space is large enough to facilitate manual operation.

The two inclined supporting plates 15 connected with the end lower beam 123 are provided with a reinforcing plate 126 at one disconnected end, and the bottom ends of the reinforcing plates 126 are connected with the end lower beam 123 so as to reinforce the strength of the inclined supporting plates 15 at the disconnected part.

Further, a rear end connecting plate 17 is arranged at the middle position of the end upper beam 121 and the corner post 112 of the end frame 12, and each rear end connecting plate 17 is connected with each inclined supporting plate 15 in sequence. When the outer diameter of the can body 2 is small, the connecting ring 3 for connecting the can body 2 is connected to the inclined support plate 15 and the rear end connecting plate 17. In another embodiment, when the outer diameter of the can body 2 is large, the coupling ring 3 coupling the can body 2 is coupled with the inclined support plate 15 and the corner post 123, and thus, in this case, the rear end coupling plate is not necessary.

Further, referring to fig. 7, fig. 7 is a schematic view of the structure of the frame of the tank container of the present invention at another angle, and the inclined support plates 15 of the end frame 12 are located at the inner side of the end frame 12 close to the transverse center plane P of the frame 1, so that sufficient space for installing accessories, such as ladders, valves, etc., is left in the space in the frame of the end frame 12 (i.e., the space defined by the widths of the two corner posts, the end upper beam and the end lower beam). Specifically, the inclined support plates 15 extend from the plane of the inner end surface of the end frame 12 toward the center of the end frame 12, and are located on the same plane as the inner end surface of the end frame 12, wherein the inner end surface of the end frame 12 is the plane of the inner end surfaces of the two corner posts 122, the end upper beam 121, and the end lower beam 112 facing the transverse center plane P of the frame 1. Inclined support plate 15 sets up in one side that end frame 12 is close to frame 1 horizontal central plane P, and lies in the coplanar with the interior terminal surface of end frame 12, on the one hand as much as possible leave space installation annex, on the other hand also guarantees that each inclined support plate 15 can be connected with clamping ring 3 at the coplanar, guarantees the fastness and the reliability of connecting.

Thus, each rear end connecting plate 17 and each inclined support plate 15 are located on the same plane. Guarantee that each rear end connecting plate 17 and each inclined support plate 15 can be connected with clamping ring 3 at the coplanar, guarantee the fastness and the reliability of connecting.
