[0048] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0049] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are only for the purpose of illustration and are not intended to be limiting.

[0050] In this document, ordinal numbers such as “first” and “second” cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order.

[0051] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0052] The utility model provides a frame box. The frame box can be a 50-foot box. The frame box has a two-layer structure. Both layers of the frame box can be used to transport vehicles. The height size of the corner post assembly 210 of the frame box can be changed. In this way, when the frame box is loaded with a vehicle, if it is necessary to hoist the frame box, the top of the corner post assembly 210 is positioned higher than the top of the vehicle located on the upper layer, so that the corner post assembly 210 can be connected by a hoist for hoisting. When the frame box loaded with a vehicle is transported by rail, the top of the corner post assembly 210 can be made lower than the top of the vehicle located on the upper layer, so as to avoid the corner post assembly 210 from colliding with objects on both sides of the railway during the railway transportation (such as the top wall of the railway tunnel, etc.).

[0053] Please refer to Figures 1 to 6 The frame box includes a first frame 250 and a second frame 260. The structures of the first frame 250 and the second frame 260 are substantially the same as the structure of the bottom frame of the container.

[0054] The second rack 260 is located directly above the first rack 250. The second rack 260 is spaced apart from the first rack 250. The length directions of the first rack 250 and the second rack 260 are parallel. The width directions of the first rack 250 and the second rack 260 are parallel.

[0055] The frame box further includes a corner post assembly 210. The corner post assembly 210 includes a fixed corner post 211. The bottom end of the fixed corner post 211 is connected to the first frame 250. The fixed corner post 211 is connected to the second frame 260. In this way, the fixed corner post 211, the first frame 250 and the second frame 260 form a substantially rectangular parallelepiped structure. In this way, the first frame 250 and the second frame 260 form a two-layer structure. Both the first frame 250 and the second frame 260 can be used to carry vehicles. For example, the first frame 250 is used to carry a first vehicle 270. The second frame 260 is used to carry a second vehicle 271. The height of the second vehicle 271 can be greater than the height of the first vehicle 270.

[0056] It will be appreciated that in an embodiment not shown, the height of the second vehicle may be equal to or less than the height of the first vehicle.

[0057] like Figure 1 and Figure 2 As shown, the second frame 260 is located between the top and bottom ends of the fixed corner column 211. In this way, part of the fixed corner column 211 is located above the second frame 260. The frame box also includes a guardrail 290. The guardrail 290 is located above the second frame 260. The guardrail 290 is connected to the second frame 260 and the part of the fixed corner column 211 located above the second frame 260. In this way, the protection of the upper layer of the frame box can be increased, and the frame box can be used safely.

[0058] like Figures 1 to 6As shown, the corner post assembly 210 further includes a movable corner post 212. The movable corner post 212 can be connected to the fixed corner post 211. In this way, the movable corner post 212 has a first position and a second position.

[0059] like Figure 1 and Figure 5 As shown, when the movable corner post 212 is in the first position, the movable corner post 212 is connected to the fixed corner post 211. At this time, the length direction of the movable corner post 212 and the length direction of the fixed corner post 211 are both parallel to the vertical direction. The top end of the movable corner post 212 is higher than the top end of the fixed corner post 211. The bottom end of the movable corner post 212 is overlapped to the top end of the fixed corner post 211. The height dimension of the whole formed by the movable corner post 212 and the fixed corner post 211 is the first dimension.

[0060] like Figure 2 As shown, when the movable corner post 212 is located at the second position, the height dimension of the whole formed by the movable corner post 212 and the fixed corner post 211 is the second dimension. The first dimension is greater than the second dimension.

[0061] In this way, Figure 1 As shown, when the frame box loaded with the vehicle needs to be hoisted by the hoist, the movable corner post 212 can be located at the first position. In this way, the top end of the movable corner post 212 is located higher than the top of the vehicle located on the second frame 260. The hoist can be connected to the top end of the movable corner post 212.

[0062] like Figure 2 and Figure 3 As shown, when the frame box loaded with the vehicle needs to be transported by rail, the movable corner post 212 can be placed in the second position. At this time, along the vertical direction, the dimension between the top surface of the corner post assembly 210 (the top surface of the fixed top corner piece 222 described later) and the bottom surface of the bottom corner piece 221 described later is not greater than the preset dimension. The preset dimension can be determined according to the railway boundary. For example, the preset dimension ranges from 3500 mm to 3600 mm. Further, the preset dimension can be 3570 mm. In this way, the corner post assembly 210 and the boundary 280 described later are prevented from overlapping, thereby preventing the corner post assembly 210 from being bumped during transportation, and ensuring the safety of transportation by rail.

[0063] Railway limits refer to the outline dimension lines (boundary 280) that cannot be crossed between buildings, equipment and locomotives and vehicles on the line to ensure transportation safety. There are two types: building approach limits and locomotive and vehicle limits, collectively known as the basic limits of railways. The former is the outline line that buildings on both sides of the railway line are not allowed to intrude; the latter is the outline line that locomotives and vehicles themselves and the goods they carry are not allowed to cross, and a certain gap should be left between the two.

[0064] In this embodiment, the arrangement of the first frame 250 and the second frame 260 enables the frame box to transport at least two layers of vehicles, with high transportation efficiency; in addition, the arrangement of the movable corner column 212 and the fixed corner column 211 enables the frame box loaded with vehicles to be hoisted by a sling and transported by rail.

[0065] Alternatively, if Figures 4 to 6 As shown, a rotary lock 216 is provided at the bottom end of the movable corner post 212. The rotary lock 216 may be an existing rotary lock for containers, which will not be described in detail here. A fixed top corner piece 222 is provided at the top end of the fixed corner post 211. When the movable corner post 212 is located at the first position, the rotary lock 216 extends into the fixed top corner piece 222 and can be locked to the fixed top corner piece 222. In this way, the movable corner post 212 located at the first position can be prevented from leaving the first position during the hoisting process.

[0066] Alternatively, if Figure 6 As shown, the rotary lock 216 has a rotary lock handle 217. The rotary lock handle 217 is located in the movable corner post 212. The movable corner post 212 has an operating hole 218. The position of the operating hole 218 corresponds to the position of the rotary lock handle 217. In this way, the operating hole 218 is directly opposite to the rotary lock handle 217, and the rotary lock handle 217 can be operated through the operating hole 218. Therefore, the rotary lock 216 can be prevented from being misoperated. In addition, the operating hole 218 can reduce the weight of the movable corner post 212, thereby facilitating the operation of the movable corner post 212.

[0067] Optionally, please continue to refer to Figure 6 , the rotary lock 216 is located at the lower end surface of the movable corner post 212 (the lower end surface of the movable corner post 212 when the movable corner post 212 is located at the first position). The fixed top corner piece 222 has a top corner hole 223. When the movable corner post 212 is located at the first position, the rotary lock 216 extends into the top corner hole 223 of the fixed top corner piece 222. Therefore, the structure of the movable corner post 212 is simple.

[0068] Optionally, refer to Figures 4 to 6 The movable corner post 212 is rotatably connected to the top end of the fixed corner post 211 to rotate between the first position and the second position. Thus, the movable corner post 212 can be prevented from being lost.

[0069] Please refer to Figure 2 and Figure 4After the movable corner post 212 leaves the first position, the movable corner post 212 can automatically flip to the second position under the action of its own gravity. When the movable corner post 212 is in the second position, the length direction of the movable corner post 212 is parallel to the length direction of the fixed corner post 211, and is located to the side of the fixed corner post 211. In other words, during the process of the movable corner post 212 rotating from the first position to the second position, the movable corner post flips 180 degrees. In this way, the horizontal size of the movable corner post 212 in the second position can be reduced.

[0070] It is understood that in an embodiment not shown, when the movable corner post is located at the second position, the length direction of the movable corner post intersects (e.g., is perpendicular to) the length direction of the fixed corner post and is located to the side of the fixed corner post. That is, when the movable corner post rotates from the first position to the second position, the movable corner post flips 90 degrees.

[0071] Furthermore, if Figures 4 to 6 As shown, the frame box includes a first ear 213 and a second ear 214. An end of the movable corner column 212 provided with a rotary lock 216 is provided with an extended protruding first ear 213. There are two first ears 213. The two first ears 213 are arranged at intervals. The top end of the fixed corner column 211 is provided with a second ear 214 extending and protruding in the horizontal direction. There are two second ears 214. The two second ears 214 are arranged at intervals.

[0072] The frame box further includes a pivot shaft 215. The second lug 214 is located between the two first lugs 213. The pivot shaft 215 passes through the first lug 213 and the second lug 214. In this way, the movable corner post 212 is pivotally connected to the fixed corner post 211 through the pivot shaft 215. The pivot shaft 215 is located on the side of the fixed corner post 211 in the horizontal direction. As a result, the structures of the movable corner post 212 and the fixed corner post 211 are simple.

[0073] Alternatively, if Figure 6 As shown, the first ear 213 includes a first arm 293 and a second arm 294. One end of the first arm 293 is connected to the movable corner post 212 and extends out of the movable corner post 212. The other end of the first arm 293 is connected to the second arm 294. The length direction of the first arm 293 and the length direction of the second arm 294 intersect. One end of the second arm 294 is pivotally connected to the second ear 214 through a pivot shaft 215. In this way, the movable corner post 212 can be rotated 180 degrees. In addition, the strength of the first ear 213 is large.

[0074] Furthermore, the first arm 293 and the second arm 294 form an L-shaped structure. Therefore, the structure of the first ear 213 is simple.

[0075] It is understood that in an embodiment not shown, the movable corner post is detachably connected to the top end of the fixed corner post. In this way, when the movable corner post is connected to the fixed corner post, the movable corner post is located at the first position. When the movable corner post is separated from the fixed corner post, the movable corner post is located at the second position. At this time, the movable corner post can be stored in the second frame.

[0076] Alternatively, if Figures 1 to 3 As shown, the first frame 250 and the second frame 260 are both provided with a porous steel floor 291. The porous steel floor 291 is used to carry vehicles. In this way, the vehicle can be tied through the porous steel floor 291. The frame box also includes a ladder 292. The ladder 292 connects the first frame 250 and the second frame 260. The ladder 292 extends from the first frame 250 to the second frame 260. Therefore, the second frame 260 can be climbed up through the ladder 292.

[0077] like Figures 4 to 6 As shown, a movable top corner piece 220 is provided at the top end of the movable corner post 212. A bottom corner piece 221 is provided at the bottom end of the fixed corner post 211. When the movable corner post 212 is located at the first position, the frame boxes can be stacked through the movable top corner piece 220 of the movable corner post 212 and the bottom corner piece 221 of the fixed corner post 211. When the movable corner post 212 is located at the second position, the frame boxes can be stacked through the fixed top corner piece 222 of the fixed corner post 211 and the bottom corner piece 221 of the fixed corner post 211. The frame boxes can also be hoisted through the fixed top corner piece 222 of the fixed corner post 211 or the movable top corner piece 220 of the movable corner post 212.
