[0086] The present application provides a kind of transport box, it can be used to load car or other ordinary goods, it can be used for railway transport or ship transport etc.

[0087] Now, the accompanying drawings will be referred to Figures 1 to 10The exemplary embodiments according to the utility model are described in more detail.

[0088] As Figures 1 to 3 shown, the utility model provides a kind of transport case 100, and transport case 100 includes box 10 and at least one set of movable top cover 20, and box 10 includes the side wall 11 of two sides in the width direction D2 of transport case 100, and each set of movable top cover 20 includes two pivot plates 21, one lifting plate 22 and several connecting devices 23.Two pivot plates 21 are spaced apart in the width direction D2, and are pivotably connected to the top end of two side walls 11 respectively, for example, connected to the top end of the top side beam of box 10.The pivot axis of pivot plate 21 is arranged along the length direction D1 of box 10.Pivot plate 21 includes pivot end 211 pivotably connected to the top end of side wall 11 and support end 212 away from pivot end 211.Lifting plate 22 is located above two pivot plates 21, and lifting plate 22 can move up and down along the height direction D3 of transport case 100, to make movable top cover 20 be in closed state or open state.Connecting device 23 connects pivot plate 21 and lifting plate 22, and drives pivot plate 21 to pivot in the up and down movement of lifting plate 22. Among them, in the closed state of movable top cover 20, two pivot plates 21 are in the same plane, and the support end 212 of two pivot plates 21 is opposite, and the lifting plate 22 is placed on the upper surface of pivot plate 21, that is, the lifting plate 22 and the two pivot plates 21 are in the state of being substantially horizontal, so that the transport case 100 is flat roof.In the open state of movable top cover 20, the support end 212 of two pivot plates 21 supports lifting plate 22, that is, the lifting plate 22 is in the state of being substantially horizontal, and two pivot plates 21 are inclined, and the top of transport case 100 is protruded upward by the side wall 11 of box 10.It can be understood that the position of lifting plate 22 in open state is higher than that in closed state.

[0089] According to the utility model, in the open state of movable top cover, the loading space of transport case is larger, can load larger size goods or more amount of goods, and the application range is wide.In the closed state of movable top cover, the transport case is flat roof, convenient hoisting, stacking, billing according to standard case, and the transportation cost is low.

[0090] It should be noted that transport case 100 can include two or more sets of movable top cover 20.As Figure 4 and Figure 5 shown, transport case 100 includes three sets of movable top cover 20, and three sets of movable top cover 20 are arranged along the length direction D1.It can be understood that multiple sets of movable top cover 20 can be in open state simultaneously, or selectively make part of movable top cover 20 be in open state.Movable top cover 20 can be opened or closed under the action force applied in the box or outside the box.

[0091] In one possible implementation, the pivot plate 21 is provided with a guide rail 24 extending perpendicularly to the pivot shaft, and the connecting device 23 comprises a roller 25 which rolls along the guide rail 24, i.e. the connecting device 23 is in sliding connection with the pivot plate 21, and the connecting device 23 slides in a direction away from the pivot shaft as the lifting plate 22 moves upward. The roller 25 is located below at least part of the structure of the guide rail 24 to drive the pivot plate 21 to pivot through the guide rail 24.

[0092] Specifically, the guide rail 24 comprises a connecting portion 241 and an abutting portion 242 (see Figure 7 ), at least part of the lower surface of the abutting portion 242 is used to abut against the roller 25, the connecting portion 241 is connected to the abutting portion 242 and the pivot plate 21, i.e. the connecting portion 241 is used to fixedly connect the abutting portion 242 with the pivot plate 21, and the roller 25 is located below the abutting portion 242. For example, the guide rail 24 can be substantially T-shaped or horizontally H-shaped, or other irregular shapes.

[0093] As shown in Figure 6 and Figure 7 , the connecting device 23 further comprises a roller holder 26, which comprises a limiting plate 261 and a groove plate 263, the limiting plate 261 is connected to the groove plate 263, the groove plate 263 is located above the guide rail 24, and the two limiting plates 261 are respectively located on both sides of the guide rail 24, so that the roller holder 26 is in an inverted groove shape. One end of the groove plate 263 is pivotably connected to the lifting plate 22. The roller 25 is connected to the limiting plate 261 and located below the abutting portion 242. Thus, when the lifting plate 22 and the connecting device 23 move upward, the roller 25 of the connecting device 23 abuts against the lower surface of the abutting portion 242 of the guide rail 24, thereby driving the pivot plate 21 to rotate upward.

[0094] Referring back to Figure 3 , during the upward or downward movement of the lifting plate 22, the end of the connecting device 23 connected with the lifting plate 22 is away from the guide rail 24, so the roller 25 is movable relative to the groove plate 263 during the upward or downward movement of the lifting plate 22. Therefore, to achieve the installation of the roller 25 and the roller holder 26, as shown in Figure 6 , the connecting device 23 further comprises an anti-disengagement component 252, the roller 25 comprises a support shaft 251 extending along the central axis of the roller 25, and the limiting plate 261 is provided with an elongated hole 262, and the support shaft 251 is connected to the anti-disengagement component 252 through the elongated hole 262. It can be understood that the roller 25 is located in the groove formed by the roller holder 26, the anti-disengagement component 252 is located outside the groove, and after the support shaft 251 is connected to the anti-disengagement component 252, the anti-disengagement component 252 cannot pass through the elongated hole 262. Thus, the roller 25 is installed to the roller holder 26 and can move along the elongated hole 262.

[0095] It can be understood that, in the process of moving the lifting plate 22 from the closed state of the movable top cover 20 to the open state, the rollers 25 move in the long holes 262 from the upper end of the long holes 262 to the lower end of the long holes 262, and then to the upper end of the long holes 262.

[0096] Preferably, each of the two limiting plates 261 is provided with a roller 25 to balance the force on both sides of the guide rail 24. It should be noted that, in one implementation, the two rollers 25 are respectively connected to the two limiting plates 261, i.e. each roller 25 is connected to the limiting plate 261 through a respective support shaft 251, and in another implementation, the two rollers 25 can be coaxially arranged. For example, the guide rail 24 is provided with a strip-shaped hole extending along the extension direction of the guide rail 24, and the shafts of the two rollers 25 pass through the strip-shaped hole to be connected to the two limiting plates 261.

[0097] Preferably, the limiting plate 261 is provided with two long holes 262 at intervals, and the two rollers 25 are respectively installed in the two long holes 262 of the same limiting plate 261. That is, along the extension direction of the guide rail 24, two rollers 25 can be provided, for example, the connecting device 23 is provided with four rollers 25 in total. The size of the two long holes 262 can be set according to the specific needs of different positions, for example, the size of the long hole 262 close to the lifting plate 22 is larger. This design can disperse the force of the connecting device 23 on the guide rail 24 to multiple rollers 25, reduce the structural strength requirement of a single roller 25, and make the movement of the connecting device 23 and the pivot plate 21 more stable.

[0098] In some preferred embodiments, at least one side of the lifting plate 22 in the width direction D2 is connected to the pivot plate 21 through at least two connecting devices 23. In other words, one side of the lifting plate 22 is connected to the pivot plate 21 through at least two connecting devices 23 arranged at intervals in the length direction D1. It can be understood that at least two guide rails 24 are correspondingly arranged on the pivot plate 21. As shown in Figure 4 Each side of the lifting plate 22 is connected to the pivot plate 21 through six connecting devices 23, and at least six guide rails 24 are arranged on the pivot plate 21, i.e. each set of movable cover plate includes twelve connecting devices 23.

[0099] Further preferably, a set of movable top cover 20 further comprises a connecting plate 27 extending along the length direction D1 and fixedly connected to at least two connecting devices 23. Therefore, the connecting plate 27 can realize the synchronous movement of the multiple connecting devices 23 connecting the lifting plate 22 and the pivot plate 21. Optionally, the connecting plate 27 covers the top of the groove plate 263 and is fixedly connected to the groove plate 263, which can simultaneously have a protective effect on the roller frame 26. Of course, the connecting plate 27 can also be connected to the lower side of the groove plate 263.

[0100] As shown in Figure 7 andFigure 8 As shown, the transport box 100 further comprises upper folding plates 28 and lower folding plates 29. Specifically, the two ends of the box body 10 along the length direction D1 are fixedly connected with lower folding plates 29 on the side facing the inside of the box, for example, the lower folding plates 29 are connected to the top end beam 12 of the box body 10. The upper folding plates 28 are fixedly connected to at least one end of the pivoting plate 21 along the length direction D1. In the closed state of the movable cover plate, the upper folding plates 28 are pressed on the lower folding plates 29. The lower folding plates 29 at both ends of the box body 10 have a supporting effect on the movable cover plate in the closed state.

[0101] For example, the transport box 100 comprises a set of movable top covers 20, and the upper folding plates 28 are fixedly connected to both ends of the pivoting plate 21 along the length direction D1. In the closed state of the movable cover plate, the upper folding plates 28 at both ends of the pivoting plate 21 are respectively pressed on the lower folding plates 29 at both ends of the box body 10.

[0102] When the transport box 100 comprises at least two sets of movable top covers 20 arranged along the length direction D1, the at least two sets of movable top covers 20 comprise a first set of movable top covers 20 and at least a second set of movable top covers 20. The upper folding plates 28 of the pivoting plate 21 of the first movable top cover 20 are fixedly connected to both ends along the length direction D1, and the upper folding plates 28 and the lower folding plates 29 of the pivoting plate 21 of the second movable top cover 20 are respectively fixedly connected to both ends along the length direction D1. The upper folding plates 28 of a set of movable top covers 20 are pressed on the lower folding plates 29 of the adjacent movable top cover 20.

[0103] For example, the transport box 100 comprises two sets of movable top covers 20 arranged along the length direction D1, i.e. a first set of movable top covers 20 and a second set of movable top covers 20. The upper folding plates 28 at both ends of the first movable top cover 20 are respectively pressed on the lower folding plates 29 of the box body 10 and the lower folding plates 29 of the second movable top cover 20, and the upper folding plates 28 of the second movable top cover 20 are pressed on the lower folding plates 29 at the other end of the box body 10. For example, the transport box 100 comprises three sets of movable top covers 20 arranged along the length direction D1, i.e. a first set of movable top covers 20 and two sets of second movable top covers 20. The first movable top cover 20 can be located between the two sets of second movable top covers 20, and the upper folding plates 28 at both ends thereof are respectively pressed on the lower folding plates 29 of the two sets of second movable top covers. The first movable top cover 20 can also be arranged to press on the lower folding plates 29 of the box body 10 at both ends and the lower folding plates 29 of the adjacent second movable top cover 20.

[0104] To improve the sealing between the movable top cover 20 and the box body 10, the upper folding pressing plate 28 and the lower folding pressing plate 29 are both configured as a groove 341, the groove 341 of the upper folding pressing plate 28 is configured to open downward, and the groove 341 of the lower folding pressing plate 29 is configured to open upward. The upper end of one side edge of the lower folding pressing plate 29 abuts against the groove bottom of the upper folding pressing plate 28. Specifically, the upper folding pressing plate 28 comprises a first fixed part 281, an upper end part 282, and a lower extension part 283, the first fixed part 281 and the lower extension part 283 respectively extend downward from both ends of the upper end part 282 to form the groove 341 opening downward, and the first fixed part 281 is connected with the end part of the pivoting plate 21. The lower folding pressing plate 29 comprises a second fixed part 291, a lower end part 292, and a support part 293, the second fixed part 291 and the support part 293 respectively extend upward from both ends of the lower end part 292 to form the groove 341 opening upward. Among them, in the closed state of the movable top cover 20, the upper end of the support part 293 abuts against the lower surface of the upper end part 282. Preferably, a sealing rubber strip is arranged at the pressing joint of the upper folding pressing plate 28 and the lower folding pressing plate 29.

[0105] The transport box 100 further comprises a fixing device 30 for keeping the movable top cover 20 in the open state. In some specific embodiments, as shown in Figure 9 and Figure 10 , the fixing device 30 comprises a support rod 31 and a fixing part 32. The support rod 31 is used to support the pivoting plate 21, and the fixing part 32 is arranged on the side wall 11 of the box body 10 to support the support rod 31. Correspondingly, the lower surface of the pivoting plate 21 is fixedly connected with a limiting part 34, and the limiting part 34 has a groove 341 for the support rod 31 to insert in the open state. Thus, the support rod 31 cannot slide on the pivoting plate 21, and the support on the pivoting plate 21 is more stable.

[0106] In the open state of the movable top cover 20, the support rod 31 moves upward to support the pivoting plate 21 and is fixed to the fixing part 32. In the closed state of the movable top cover 20, the support rod 31 can move downward and be fixed to the fixing part 32. For example, the fixing part 32 is provided with a through hole, the support rod 31 is arranged in the through hole and can move up and down. The support rod 31 is provided with a pin 33, the pin 33 is inserted into the support rod 31 above the fixing part 32, and the pin 33 abuts against the upper surface of the fixing part 32 to prevent the support rod 31 from moving downward. The support rod 31 is provided with at least two pin holes at intervals, or the side wall 11 of the box body 10 is provided with at least two fixing parts 32 to fix the support rod 31 at different positions.

[0107] In a preferred embodiment, the support rod 31 is provided with two pin rods 33 spaced apart in the up-down direction, wherein the first pin rod 33 is located above the second pin rod 33, and the side wall 11 of the box body 10 is provided with two fixing members 32 spaced apart in the up-down direction, wherein the first fixing member 32 is located above the second fixing member 32. The spacing between the first pin rod 33 and the second pin rod 33 is equal to the spacing between the first fixing member 32 and the second fixing member 32. In the supporting state of the support rod 31 (the support rod 31 supports the pivoting plate 21), the first pin rod 33 abuts against the upper surface of the first fixing member 32, and the second pin rod 33 abuts against the upper surface of the second fixing member 32. In the non-supporting state of the support rod 31 (the support rod 31 does not support the pivoting plate 21), the first pin rod 33 abuts against the upper surface of the second fixing member 32. In the above-mentioned embodiment, the support rod 31 is supported by two fixing members 32, the structure is not easy to be damaged, and can bear greater force.
