In the utility model, the main box 1 and the side boxes 2 are containers, and can also be other devices similar to standard boxes. The container is provided with necessary corner fittings, corner posts, side plates, top plates, bottom plates and various beams, and a truss which can provide enough support is also arranged in the container. The same type of container has the same dimensions, e.g., a 40 foot container and a 20 foot container, with the same cross-sectional area, differing only in length. In the present utility model, the main tank 1 and the side tank 2 have the same height and different lengths.

The side surface of the main casing 1 is a side surface in the longitudinal direction of the main casing 1 when the main casing 1 is placed horizontally, as shown in the left-right direction in fig. 1. The side of the main tank 1 is provided with a first opening 10, according to one embodiment of the utility model, the bottom edge of the first opening 10 is flush with the floor of the main tank 1. According to one embodiment of the utility model, the upper and lower edges of the first opening 10 are flush with the upper and lower edges of the main tank 1.

In the present utility model, the first opening 10 is provided in the main casing 1 in order to realize a function of communicating with the space of the side casing 2 and in order to form a passage through which a user enters and exits. The first opening 10 being larger than the second opening 20 means that the length of the first opening 10 is larger than the length of the second opening 20 in a direction extending along the bottom plate of the main tank 1.

The first opening 10 may be formed in the center of the side of the main tank 1 or may be offset from the center to the edge of the side of the main tank 1. The first opening 10 may be provided with a detachable cover plate, which is mounted to the first opening 10 when transportation is required and removed when the side case 2 is required.

The support column 11 is located in the plane where the first opening 10 is located, the top of the support column 11 is connected with the top beam of the main box 1, the bottom of the support column 11 is connected with the bottom beam of the main box 1, the support column 11 divides the first opening 10 into three parts, namely a front opening, a middle opening and a rear opening, and the middle part is used for being in butt joint with the second opening 20. The vertical direction refers to the up-down direction as shown in fig. 1.

The support columns 11 provide structural support for the main tank 1, and may be part of a support truss or may be provided separately. The support columns 11 simultaneously provide mounting locations for the side tanks 2 and bear downward and sideways forces of the side tanks 2.

The side surface of the side case 2 means a side surface in the longitudinal direction of the side case 2 when the side case 2 is placed horizontally. The side surface of the side case 2 is provided with a second opening 20, and the bottom edge of the second opening 20 is flush with the bottom plate of the side case 2, or the upper and lower edges of the second opening 20 are flush with the upper and lower edges of the side case 2. The second opening 20 may cover the entire side surface of the side case 2 in the longitudinal direction of the side case 2, or may cover a partial side surface of the side case 2. The correspondence of the first opening 10 and the second opening 20 allows the space of the side tank 2 to communicate with the space of the main tank 1. According to an embodiment of the present utility model, the bottom edges of the first and second openings 10 and 20 are flush, and the bottom plate of the main tank 1 and the bottom plate of the side tank 2 are flush, so that the bottom plates of the main tank 1 and the side tank 2 are integrally connected by the aforementioned hanging point structure.

When the second opening 20 of the side case 2 is installed in alignment with the first opening 10 of the main case 1, the first opening 10 is not completely covered by the side case 2, the front and rear openings remain exposed, and the front and rear openings may be provided with access platform 12 or the like.

The pillar 21 may be provided at an edge of the second opening 20, for example, when the second opening 20 covers the entire side of the side case 2, the pillar 21 is located at the edge of the second opening 20. According to an embodiment of the utility model, the uprights 21 may be arranged in the second opening 20, for example, when the second opening 20 covers the entire side of the side case 2, the two uprights 21 are located in the second opening 20 at a distance from the front and rear edges of the second opening 20 in the vertical direction, respectively. According to an embodiment of the present utility model, the pillar 21 may be disposed outside the second opening 20, for example, when the second opening 20 does not cover the entire side of the side case 2, the second opening 20 is disposed between the front and rear edges of the side case 2, and the pillar 21 may be disposed at both front and rear sides of the second opening 20.

The spacing between the two support columns 11 is kept identical to the spacing between the two columns 21 so that the support columns 11 correspond to the columns 21. For example, the two support columns 11 correspond to the two columns 21 of the front and rear edges of the second opening 20, respectively. The hooking structure 111 on the supporting column 11 corresponds to the hooking point structure 211 on the upright column 21 in position relation, when the hooking structure 111 is clamped in the hooking point structure 211, the side box 2 is fixed on the side surface of the main box 1, and the first opening 10 is correspondingly communicated with the second opening 20.

The number of the bridge pieces 112 is 3 uniformly arranged along the support column 11. Correspondingly, a plurality of hanging point structures 211 and supporting members 212 arranged on the upright posts 21 can be arranged.

The side tanks 2 may be complete containers or may be half or more. When the side case 2 is a half container, for example, formed by cutting the entire container in the longitudinal direction, the second opening 20 is an opening when the container is cut longitudinally, covering the entire side face of the side case 2. At this time, the upright posts are welded at the two ends of the opening surface of the side box 2, so that the strength of half of the side box is improved, and the side box is conveniently connected with the main box 1. The corresponding positions of the two support columns 11 are two vertical edges of the side box 2, and the support columns 11 are respectively provided with a fixing buckle of the platform 12 and a fixing device of the side box 2, so that more stable fixing can be provided.

In the utility model, the side box is detachably arranged on the side surface of the main box, and the space in the box body can be expanded through the mutual correspondence of the first opening and the second opening. By adopting the connecting structure, the expanded box body can keep stable, the supporting force of the main box on the side box is dispersed to each part of the upright post and the supporting column, the local overstresses of the side box and the main box can be avoided, and the main box and the side box are not deformed. The flexible disassembly structure arranged on the support column and the upright column can facilitate the switching of the transportation state and the operation state of the box body.
