Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please refer to Figures 1 to 5 This utility model embodiment provides a folding container with a movable shelf 20, comprising:

[0032] Base frame 10;

[0033] Angle post 30 is set at the corners of both ends of the base frame 10. The angle post 30 is hinged to the base frame 10. A guide rail plate 31 is fixed on the inner side of the middle part of the angle post 30. The guide rail plate 31 is provided with a plurality of first mounting holes 311 arranged along the extension direction of the guide rail plate 31.

[0034] The movable layer plate 20 is parallel to the base frame 10, and two installation grooves 22 are arranged on the two sides of the movable layer plate 20, respectively. The two installation grooves 22 are located close to the two end faces 21 of the movable layer plate 20, and are used for the up-down sliding of the guide rail plate 31. The installation groove 22 is gap-fitted with the guide rail plate 31, and a second installation hole 24 corresponding to the first installation hole 311 is arranged on the side of the installation groove 22 facing the end face 21. The first locking pin 50 passes through the second installation hole 24 and the first installation hole 311 in sequence, so as to fixedly connect the movable layer plate 20 and the guide rail plate 31.

[0035] The reinforcing column 40 is arranged on the two sides of the middle part of the base frame 10. The reinforcing column 40 comprises at least two sleeve pipes, namely an outer sleeve pipe 42 and an inner sleeve pipe 41 which is sleeved in the outer sleeve pipe 42 and can slide up and down relative to the outer sleeve pipe 42. The inner sleeve pipe 41 is fixed with the outer sleeve pipe 42 through the second locking pin 60. The outer sleeve pipe 42 is hinged with the base frame 10. The top end of the inner sleeve pipe 41 is provided with a clamping groove 44 facing the movable layer plate 20. The two sides of the movable layer plate 20 are provided with clamping blocks 27 clamped with the clamping groove 44.

[0036] The folding container of the embodiment can be specifically used for transporting small cars, and of course, the container can also be used for transporting other goods.

[0037] Specifically, the cross-sectional shape of the base frame 10 and the movable layer plate 20 can be rectangular. The corner column 30 is arranged at the four corners of the base frame 10. One end of the base frame 10 is provided with two corner columns 30. A support cross beam can be arranged between the two corner columns 30 at the same end, so as to reinforce the support strength of the two corner columns 30 at the same end.

[0038] As shown in Figure 1 , 5 Specifically, the length of the guide rail plate 31 is less than the length of the corner column 30, so that the guide rail plate 31 is arranged on the inner side of the middle part of the corner column 30. The container is divided into two layers by the movable layer plate 20. The up-down sliding of the movable layer plate 20 on the guide rail plate 31 can adjust the distance between the movable layer plate 20 and the base frame 10, so that the container can be adapted to more height sizes of cars.

[0039] As shown in Figure 2 , the guide rail plate 31 is fixedly arranged on the inner side of the corner column 30. The guide rail plate 31 extends along the length direction of the corner column 30. The installation groove 22 is gap-fitted with the guide rail plate 31, so that the movable layer plate 20 can slide up and down along the length direction of the guide rail plate 31. The distance between the movable layer plate 20 and the base frame 10 can be arbitrarily adjusted according to the requirement, and the guide rail plate 31 is fixed with the movable layer plate 20.

[0040] When installing the movable shelf 20, the mounting groove 22 of the movable shelf 20 slides from above or below the guide rail 31 onto the guide rail 31, so that the movable shelf 20 is installed with the guide rail 31. In this way, the sliding direction of the sliding shelf can be restricted, and it can only slide up and down. In addition, the clearance fit between the mounting groove 22 and the guide rail 31 can reduce the friction between the two and avoid wear.

[0041] Specifically, mounting plates 23 are provided on both sides of the end face 21, the second mounting hole 24 is located on the mounting plate 23, the bottom of the mounting plate 23 is provided with a first positioning groove 231 corresponding to the first mounting hole 311, the first locking pin 50 passes through the first mounting hole 311, the first positioning groove 231 abuts against the first locking pin 50, so that the movable layer plate 20 is positioned.

[0042] In this embodiment, after the movable shelf 20 is loaded, it is lifted so that the mounting groove 22 of the movable shelf 20 slides up and down along the guide rail 31. After the movable shelf 20 moves to a specified height, it is first moved to a position slightly higher than the specified height. At this time, the first locking pin 50 is inserted into the first mounting hole 311 at the specified height. Then the movable shelf 20 is moved down so that it slides down along the guide rail 31 to the first positioning groove 231 and abuts against the first locking pin 50, thereby achieving positioning and initially fixing the movable shelf 20. Finally, the first locking pin 50 is inserted into the second mounting hole 24 and the first mounting hole 311 to fix the movable shelf 20 to the guide rail 31. Thus, positioning via the first positioning groove 231 can quickly fix the movable shelf 20 in the designated position, and the first positioning groove 231 abutting against the first locking pin 50 can initially fix the movable shelf 20 at the designated height, making it easier for the first locking pin 50 to pass through the mounting plate 23 and the guide rail plate 31 to fix the movable shelf 20.

[0043] In this embodiment, the first mounting hole 311 and the second mounting hole 24 are correspondingly provided. The first locking pin 50 passes through the second mounting hole 24 and the first mounting hole 311 in sequence, so that the mounting plate 23 is fixedly connected to the guide rail plate 31. Preferably, clearance grooves can be provided on both sides of the movable side plate, so that the end of the first locking pin 50 passes into the clearance groove, so as to facilitate the operator to check whether the first locking pin 50 is installed in place and ensure the reliability of the installation of the first locking pin 50.

[0044] like Figure 2 As shown, specifically, the outer side of the mounting plate 23 is provided with a downwardly bent portion 232, which is located above the second mounting hole 24 and the first positioning groove 231. The first locking pin 50 includes a pin portion 51 and a handle portion 52 fixedly connected to one end of the pin portion 51. The pin portion 51 passes through the second mounting hole 24 and the first mounting hole 311 in sequence. One side of the handle portion 52 abuts against the mounting plate 23, and one end of the handle portion 52 is inserted into the bent portion 232 and abuts against the inner wall of the bent portion 232.

[0045] Specifically, the bending part 232 comprises a first connecting part 2321 and a second connecting part 2322 connected to one end of the first connecting part 2321, the first connecting part 2321 is perpendicular to the mounting plate 23, and the second connecting part 2322 is parallel to the mounting plate 23. In this way, the first connecting part 2321, the second connecting part 2322 and the mounting plate 23 enclose a containing groove for limiting the hand-held part 52.

[0046] The hand-held part 52 comprises a third connecting part 521, a fourth connecting part 522 and a fifth connecting part 523 connected in sequence, the third connecting part 521 is perpendicular to the latch part 51 and is fixedly connected, the fifth connecting part 523 is parallel to the third connecting part 521, when the hand-held part 52 is inserted into the bending part 232 at one end, the end of the third connecting part 521 abuts against the inner side wall of the first connecting part 2321, the side wall of the third connecting part 521 abuts against the inner side wall of the second connecting part 2322, and the fourth connecting part 522 extends outward and downward from the third connecting part 521.

[0047] When the latch part 51 of the embodiment is inserted into the first mounting hole 311 and the second mounting hole 24, the hand-held part 52 needs to avoid the bending part 232, when the latch part 51 is installed in place, that is, when the side wall of the third connecting part 521 abuts against the mounting plate 23, the hand-held part 52 is rotated so that the hand-held part 52 is rotated into the containing groove formed by the bending part 232, the end surface 21 of the third connecting part 521 abuts against the inner side wall of the first connecting part 2321 to assist in supporting the movable floor 20, and the side wall of the third connecting part 521 abuts against the inner side wall of the second connecting part 2322 to limit the horizontal movement of the latch part 51.

[0048] Because the length of the container is relatively long, in order to improve the support strength of the middle part of the movable floor 20, reinforcing columns 40 can be arranged in the middle part of the movable floor 20 on both sides.

[0049] The movable floor 20 can be adjusted in height according to the height of the goods, in order to match the height of the movable floor 20, the inner sleeve 41 and the outer sleeve 42 can adjust the height of the reinforcing column 40 according to the height of the movable floor 20. The top end of the inner sleeve 41 is clamped with the clamping block 27 through the clamping groove 44, when adjusting the height of the inner sleeve 41, the clamping block 27 can be clamped into the clamping groove 44, the installation method is simple, and the height of the inner sleeve 41 can be quickly determined.

[0050] The bottom end of the corner column 30 of the folding container is hinged to the chassis 10, the inner side of the middle part of the corner column 30 is provided with a guide rail plate 31, the two sides of the movable floor plate 20 are provided with mounting grooves 22 matched with the guide rail plate 31, the movable floor plate 20 can slide up and down along the guide rail plate 31 to be adjusted to a specified position, and the guide rail plate 31 and the movable floor plate 20 are fixedly connected through the first locking pin 50, so that more height sizes of goods can be matched.

[0051] Generally, the length of the folding container is long, when the movable floor plate 20 is placed with heavy objects, the container of the embodiment is provided with the reinforcing column 40 on the two sides of the middle part of the chassis 10 to assist in supporting the movable floor plate 20 and protecting the goods placed on the chassis 10. Since the height of the movable floor plate 20 can be adjusted, in order to match the height of the movable floor plate 20, the reinforcing column 40 realizes height adjustment through the cooperation of the inner sleeve pipe 41 and the outer sleeve pipe 42 and realizes the fixation of the inner sleeve pipe 41 and the outer sleeve pipe 42 through the second locking pin 60, the bottom of the outer sleeve pipe 42 is hinged to the chassis 10, and the top of the inner sleeve pipe 41 is clamped to the movable floor plate 20, so that the reinforcing column 40 can be quickly installed with the movable floor plate 20 to realize the installation.

[0052] The corner column 30 of the utility model is hinged to the chassis 10, and the bottom of the outer sleeve pipe 42 is hinged to the chassis 10, so that the folding container is convenient to fold when not needing to load goods, the space is reduced, and in particular, when the folding container is used for return sea transportation, a plurality of folding containers can be stacked for transportation, and the cost is reduced.

[0053] Specifically, the container of the embodiment further comprises an inclined plate, one end of the inclined plate is provided with a plurality of grooves, the two end faces 21 of the chassis 10 and the movable floor plate 20 are each provided with a plurality of inclined clamping blocks 26, the plurality of inclined clamping blocks 26 are located between the corner columns 30, the number of the inclined clamping blocks 26 is the same as that of the grooves, and the inclined clamping blocks 26 are clamped into the grooves to realize fixation.

[0054] Specifically, the two sides of the movable floor plate 20 are provided with a plurality of lifting rings 25, and the lifting rings 25 are located on the upper surface of the movable floor plate 20.

[0055] When the container needs to be assembled for loading goods in two layers, the movable floor plate 20 can be stacked on the chassis 10 first, and the inclined plate is clamped with the inclined clamping blocks 26 of the movable floor plate 20. In this way, a car can directly drive onto the movable floor plate 20 through the inclined plate, or a forklift can transport goods to the movable floor plate 20 through the inclined plate, which is convenient for the forklift to load and unload goods. After the loading of the movable floor plate 20 is completed, the movable floor plate 20 can be hoisted as a whole by a crane through the lifting rings 25, the movable floor plate 20 is moved in parallel, the mounting grooves 22 are assembled with the guide rail plate 31, and the movable floor plate 20 can be fixed through the first locking pin 50 after the movable floor plate 20 reaches a specified height.

[0056] Preferably, the distance between the movable floor 20 and the chassis 10 (i.e. the specified height) is slightly greater than the height of the goods, for example, the height of the car body when the movable floor 20 is slightly higher than the height of the car body, so that the car can be conveniently assembled, and the movable floor 20 is prevented from scratching the roof of the car, thereby leaving a certain safety distance.

[0057] As shown in Figure 3 The outer sleeve 42 is sleeved with a fixed sleeve 43, the bottom of the inner sleeve 41 is provided with a plurality of third mounting holes 411, the top of the outer sleeve 42 is provided with a plurality of fourth mounting holes 421 corresponding to the third mounting holes 411, the fixed sleeve 43 is provided with a plurality of fifth mounting holes 431 corresponding to the fourth mounting holes 421, and the second locking pin 60 is sequentially aligned through the fifth mounting holes 431, the fourth mounting holes 421 and the third mounting holes 411, so that the fixed sleeve 43 is fixed with the inner sleeve 41 and the outer sleeve 42. In this way, the fixed sleeve 43 is sleeved at the connection between the outer sleeve 42 and the inner sleeve 41, so as to strengthen the structural strength of the connection between the inner sleeve 41 and the outer sleeve 42, and prevent the inner sleeve 41 from being bent at the connection with the outer sleeve 42 when the movable floor 20 is placed with heavy objects.

[0058] Preferably, the bottom of the fixed sleeve 43 is provided with a second positioning groove 432, when the inner sleeve 41 is adjusted to the specified height of the movable floor 20, the second locking pin 60 is first inserted into and then inserted out from the other side through the fourth mounting holes 421 and the third mounting holes 411, and then the fixed sleeve 43 is moved so that the second locking pin 60 abuts against the second positioning groove 432, the fixed sleeve 43 is positioned, and then the second locking pin 60 is inserted through the fifth mounting holes 431, the fourth mounting holes 421 and the third mounting holes 411 and then inserted out from the other side, so that the fixed sleeve 43 is fixed with the inner sleeve 41 and the outer sleeve 42.

[0059] In the embodiment, the width of the movable floor 20 is less than the width of the chassis 10, the bottom of the outer sleeve 42 is hingedly connected with the upper surface of the chassis 10, the top end of the inner sleeve 41 is located at the side of the movable floor 20, the top of the inner sleeve 41 is provided with a support block 45, the clamping groove 44 is arranged on the support block 45, the slot of the clamping groove 44 faces one side, and the clamping block 27 protrudes from the side of the movable floor 20, so that the clamping block 27 is clamped into the clamping groove 44.

[0060] Preferably, the width of the movable shelf 20 is smaller than the width of the base frame 10, and it is located between the reinforcing columns 40 on both sides of the base frame 10, so that when folded, the movable shelf 20 is stacked on top of the base frame 10, and the reinforcing columns 40 are folded to the side of the movable shelf 20. The folding space of the movable shelf 20 and the reinforcing columns 40 do not affect each other, which facilitates the stacking of multiple folding containers.

[0061] like Figure 4 As shown, in other embodiments, the width of the movable shelf 20 is equal to the width of the base frame 10. The bottom end of the outer sleeve 42 is provided with a buckle structure 422, and the bottom end of the outer sleeve 42 is fastened to the base frame 10 through the buckle structure 422.

One end of the latch 4221 is bent to form a hook, and the other end is rotatably connected to the rotating member 4222. When the hook is hooked onto the bottom of the outer sleeve 42, the distance between the hook and the rotation axis of the rotating member 4222 is smaller than the distance between the hook and the rotation axis of the latch 4221. When the rotating member 4222 is flipped up, the rotating member 4222 drives the rotation axis of the latch 4221 to move forward, causing the hook to move forward and disengage from the bottom of the outer sleeve 42, thus unfastening the reinforcing column 40.
