Description

Technical Field

[0001] This invention belongs to the field of container technology, and more specifically, relates to a folding container. Background Technology

[0002] A shipping container is a large container used to load goods. A collapsible container is a type of container that can be folded and compressed when empty, thus reducing its transport volume. The body of a collapsible container includes a chassis at the bottom, a top cover at the top, two end walls located between the chassis and the top cover, and two side walls, one of which has a door. When folding the container, the two end walls are folded towards the chassis first, followed by the side walls; when unfolding the container, the two side walls are unfolded first, followed by the two end walls. The top cover can be used to assist in folding or unfolding the side walls. Due to the obstruction of the top cover, it is difficult to fold or unfold the end walls using cranes or similar lifting equipment, and because the end walls are relatively heavy, it is difficult to fold or unfold them entirely manually. Summary of the Invention

[0003] The purpose of this invention is to provide a foldable container, which aims to solve the problem that it is difficult to rely entirely on manual folding or unfolding of the container end walls.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A folding container is provided, comprising a chassis, a top cover, two end walls, and two side walls. The end walls are rotatably connected to the chassis, and their rotation axes are arranged along a first horizontal direction, so that the end walls can be rotatably folded onto the chassis. The folding container also includes two traction units, each corresponding to one of the two end walls. Each traction unit includes a winding tube, a traction rope, and a drive assembly.

[0005] The winding tube is rotatably connected to the top cover.

[0006] The traction rope is wound around the winding tube, and the traction rope is fixedly connected to the corresponding end wall of the box.

[0007] A drive assembly is used to drive the winding tube to rotate, so that the winding tube can retract and extend the traction rope.

[0008] In one possible implementation, the drive assembly includes a drive turbine and a drive worm. The drive turbine is sleeved and fixed to the outside of the winding tube. The drive worm meshes with the drive turbine and is rotatably connected to the top cover.

[0009] In one possible implementation, the traction unit further includes a support and a central shaft.

[0010] The support member is fixedly connected to the top cover, and the support member has two spaced-apart first support portions.

[0011] The central shaft passes through the two first support parts.

[0012] The winding tube is located between the two first support portions and is rotatably sleeved outside the central shaft.

[0013] In one possible implementation, the space enclosed by the chassis, the top cover, the two end walls of the housing, and the two side walls of the housing is a receiving space, the traction unit is located in the receiving space, and the top cover is provided with two drive holes communicating with the receiving space, the two drive holes being aligned with the two drive worm gears respectively.

[0014] In one possible implementation, each of the box end walls is provided with a first locking component located outside the receiving space, the first locking component including a first fixing member and a first sliding shaft.

[0015] The first fastener is fixed to the end wall of the box.

[0016] The first sliding shaft is slidably inserted into the first fixing member and the top cover.

[0017] In one possible implementation, the top cover has two protrusions located on opposite outer sides of the two end walls of the housing, the receiving space has two extensions extending into the two protrusions, and two drive holes are respectively located on the bottom surfaces of the two protrusions and communicate with the two extensions.

[0018] In one possible implementation, the box sidewall includes two separate walls and a crossbeam.

[0019] Two separate walls are arranged vertically in sequence. The upper separate wall is rotatably connected to the top cover and the axis of rotation is set along the second horizontal direction. The lower separate wall is rotatably connected to the chassis and the axis of rotation is set along the second horizontal direction.

[0020] The crossbeam is positioned along the second horizontal direction and between the two split walls. The crossbeam is rotatably connected to both split walls and the axis of rotation is also positioned along the second horizontal direction.

[0021] Wherein, the second horizontal direction is perpendicular to the first horizontal direction. When the crossbeam moves into the accommodating space, the crossbeam can drive the two connected split walls to rotate and fold, so that the top cover is close to the chassis.

[0022] In one possible implementation, the sidewall of the housing is provided with support columns at both ends along the second horizontal direction. The support columns are configured separately, including a middle part, two segmented parts and two outer ends.

[0023] The middle part is fixedly connected to the crossbeam.

[0024] The two segmented parts are respectively fixedly connected to the two separate walls.

[0025] The two outer ends are fixedly connected to the top cover and the chassis, respectively.

[0026] When the two split walls rotate and fold, the two split walls can drive the two segmented parts to fold.

[0027] In one possible implementation, the support column is provided with a second locking assembly, which includes a second fixing member, a third fixing member, and a second sliding shaft.

[0028] The second fastener is fixed to one of the segments.

[0029] The third fastener is fixed to another of the aforementioned segments.

[0030] The second sliding shaft slides through the second fixing member and the third fixing member.

[0031] In one possible implementation, the support column has a guide unit on its surface away from the side wall of the housing, and the guide unit includes a first guide member.

[0032] The second guide has a plug-in portion that is inserted into the first guide in a vertical direction. The plug-in portion has a triangular block structure and its projection on the support column is triangular. The first guide and the second guide can be fixedly mounted on the two segmented portions, respectively. Alternatively, the first guide and the second guide can be fixedly connected to the segmented portion and the outer end adjacent to the segmented portion, respectively. When the two segmented portions are folded, the insertion portion can be disengaged from the first guide.

[0033] In this embodiment, when the end wall of the housing needs to be folded, the drive assembly drives the winding tube to rotate, thereby releasing the traction rope and providing an initial thrust to the end wall of the housing so that it can rotate and fold towards the chassis. When the end wall of the housing needs to be unfolded, the drive assembly drives the winding tube to rotate, causing the winding tube to retract the traction rope, thereby pulling the end wall of the housing to rotate and return to its original position. Since the traction unit can be used to fold or unfold the end wall of the housing, the problem of the difficulty of folding or unfolding the end wall of the housing entirely by hand can be avoided.

[0042] Please refer to the following: Figure 6 , Figure 8 and Figure 9 The folding container provided by the present invention will now be described. The folding container includes a chassis 11, a top cover 12, two container end walls 13 and two container side walls 14. The container end walls 13 are rotatably connected to the chassis 11 and the rotation axis is set along the first horizontal direction 21 so that the container end walls 13 can be rotatably folded onto the chassis 11. The folding container also includes two traction units 3, which correspond to the two container end walls 13 respectively. The traction unit 3 includes a winding tube 31, a traction rope and a drive assembly 32.

[0043] The winding tube 31 is rotatably connected to the top cover 12.

[0044] The traction rope is wound around the winding tube 31 and is fixedly connected to the corresponding box end wall 13.

[0045] The drive assembly 32 is used to drive the winding tube 31 to rotate so that the winding tube 31 can retract and extend the traction rope.

[0046] Compared with the prior art, the folding container provided by this invention, when the container end wall 13 needs to be folded, the drive assembly 32 drives the winding tube 31 to rotate, thereby releasing the traction rope and giving the container end wall 13 an initial thrust so that it can rotate and fold onto the chassis 11. When the container end wall 13 needs to be unfolded, the drive assembly 32 drives the winding tube 31 to rotate, thereby retracting the traction rope and pulling the container end wall 13 to rotate and return to its original position. Since the traction unit 3 can be used to fold or unfold the container end wall 13, it avoids the difficulty of relying entirely on manual folding or unfolding of the container end wall 13.

[0047] In this embodiment, one end of the traction rope can be fixedly connected to the winding tube 31. The traction rope is not shown in the accompanying drawings. The two box side walls 14 are located on both sides of the box end wall 13 along the first horizontal direction 21.

[0048] In some embodiments, see Figure 8 , Figure 18 and Figure 19 The drive assembly 32 includes a drive turbine 321 and a drive worm gear 322. The drive turbine 321 is sleeved and fixed to the outside of the winding tube 31. The drive worm gear 322 meshes with the drive turbine 321 and is rotatably connected to the top cover 12. Driving the drive worm gear 322 to rotate causes the drive turbine 321, which meshes with the drive worm gear 322, to drive the winding tube 31 to rotate, thereby realizing the function of the drive assembly 32. Through the self-locking function of the drive turbine 321 and the drive worm gear 322 when they are engaged, the end wall 13 of the housing can be stopped at any position during folding.

[0049] In this embodiment, the drive turbine 321 and the winding tube 31 can be integrally formed.

[0050] In some embodiments, see Figure 8 , Figure 18 , Figure 19 and Figure 20 The traction unit 3 also includes a support member 33 and a central shaft 34.

[0051] The support member 33 is fixedly connected to the top cover 12, and the support member 33 has two spaced-apart first support portions 331.

[0052] The central shaft 34 passes through the two first support parts 331.

[0053] The winding tube 31 is located between the two first support parts 331 and is rotatably sleeved on the outside of the central shaft 34.

[0054] The support member 33 supports the rotation of the winding tube 31 via the central shaft 34. The winding tube 31 is rotatably connected to the top cover 12 via the central shaft 34 and the support member 33.

[0055] In this embodiment, the central axis 34 can be set along the first horizontal direction 21.

[0056] Further, see Figure 18 and Figure 21The traction unit 3 also includes a limiting disc 35, which is located between two first support portions 331 and rotatably sleeved on the central shaft 34. The two end faces of the winding tube 31 are respectively in contact with the limiting disc 35 and one of the first support portions 331, and the limiting disc 35 is in contact with the other first support portion 331, thus restricting the movement of the winding tube 31 along the length of the central shaft 34. A space is left between the limiting disc 35 and the drive turbine 321 to accommodate the traction rope.

[0057] The central shaft 34 is provided with two external threads, and both external threads are threadedly connected to locking nuts 36. The two locking nuts 36 are used to clamp the two first support parts 331.

[0058] In some embodiments, see Figure 6 , Figure 8 and Figure 19 The space enclosed by the chassis 11, top cover 12, two end walls 13, and two side walls 14 forms the receiving space 15. The traction unit 3 is located within the receiving space 15. The top cover 12 has two drive holes 121 communicating with the receiving space 15, and the two drive holes 121 are respectively aligned with two drive worm gears 322. In this way, the operator can drive the drive worm gears 322 to rotate from outside the container through the drive holes 121.

[0059] Furthermore, a connector 10 is fixedly provided on the upper part of the end wall 13 of the box facing the accommodating space 15. The connector 10 has a connection hole 101. The traction rope passes through the connection hole 101 and is bound to the connector 10, thereby realizing the fixed connection between the traction rope and the connector 10.

[0060] In some embodiments, see Figure 6 and Figure 7 Each box end wall 13 is provided with a first locking component 4 located outside the accommodating space 15. The first locking component 4 includes a first fixing member 41 and a first sliding shaft 42.

[0061] The first fastener 41 is fixed to the end wall 13 of the box.

[0062] The first sliding shaft 42 is slidably inserted into the first fixing member 41 and the top cover 12.

[0063] By limiting the first sliding shaft 42 with the top cover 12, the rotation of the box end wall 13 can be restricted, thereby keeping the box end wall 13 in the unfolded state. When the box end wall 13 needs to rotate, the first sliding shaft 42 is first disengaged from the top cover 12.

[0064] Furthermore, the number of first locking components 4 provided on each box end wall 13 can be two, thus firmly restricting the rotation of the box end wall 13.

[0065] Furthermore, the first locking assembly 4 may also include a first driving rod 43, which is perpendicular to the first sliding shaft 42 and has one end fixed to the first sliding shaft 42. In this way, the first driving rod 43 can drive the first sliding shaft 42 to slide.

[0066] Furthermore, the first fixing member 41 may include a plurality of first connecting portions 411, through which the first sliding shaft 42 slides. The plurality of first connecting portions 411 are divided into two groups, and the two groups of first connecting portions 411 are respectively located on both sides of the first driving rod 43 along the axial direction of the first sliding shaft 42. The sliding stroke of the first sliding shaft 42 is limited by the limiting of the first driving rod 43 by the two groups of first connecting portions 411.

[0067] Furthermore, the first fixing member 41 is also provided with a first blocking part 412. The first blocking part 412 is located on one side of the radial direction of the first sliding shaft 42. The first blocking part 412 has a first blocking groove 4121 recessed in the direction away from the top cover 12. When the first sliding shaft 42 passes through the top cover 12, the first driving rod 43 can enter the first blocking groove 4121 through the sliding and rotation of the first sliding shaft 42, thereby restricting the first sliding shaft 42 from sliding away from the top cover 12.

[0068] In some embodiments, see Figure 6 , Figure 8 and Figure 13 The top cover 12 has two protrusions 122, which are located on opposite outer sides of the two end walls 13 of the container. The accommodating space 15 has two extensions 151, which extend into the two protrusions 122. Two drive holes 121 are respectively located on the bottom surface of the two protrusions 122 and communicate with the two extensions 151. In this way, when the container is used in outdoor spaces, rainwater can be prevented from entering the accommodating space 15 through the drive holes 121.

[0069] In this embodiment, see Figure 8 , Figure 19 , Figure 22 and Figure 23The drive worm 322 can be vertically positioned. The support member 33 also has two vertically spaced second support portions 332 and a third support portion 333, with the second support portion 332 located above the third support portion 333. The drive worm 322 is rotatably inserted into the second support portion 332 and rotatably penetrates the third support portion 333, with the gear teeth on the drive worm 322 located between the second support portion 332 and the third support portion 333. The drive worm 322 has a drive section 3221 located below the third support portion 333, and the drive section 3221 has a hexagonal prism structure. The drive worm 322 is rotatably connected to the top cover 12 via the support member 33. Thus, when it is necessary to drive the drive worm 322 to rotate, an electric wrench with a hexagonal socket can be used. The hexagonal socket of the electric wrench is inserted into the extension 151 through the drive hole 121 and fitted onto the drive section 3221. Then the drive worm 322 can be rotated by the electric wrench.

[0070] In some embodiments, see Figure 1 , Figure 4 , Figure 14 and Figure 17 The side wall 14 of the box includes two separate walls 141 and a crossbeam 142.

[0071] Two separate walls 141 are arranged in sequence along the vertical direction. The upper separate wall 141 is rotatably connected to the top cover 12 and the axis of rotation is set along the second horizontal direction 22. The lower separate wall 141 is rotatably connected to the chassis 11 and the axis of rotation is set along the second horizontal direction 22.

[0072] The crossbeam 142 is positioned along the second horizontal direction 22 and between the two split walls 141. The crossbeam 142 is rotatably connected to both split walls 141 and the axis of rotation is positioned along the second horizontal direction 22.

[0073] The second horizontal direction 22 is perpendicular to the first horizontal direction 21. When the crossbeam 142 moves into the accommodating space 15, the crossbeam 142 can drive the two connected split walls 141 to rotate and fold so that the top cover 12 is close to the chassis 11.

[0074] After both end walls 13 of the container are rotated and folded onto the chassis 11, the two crossbeams 142 can move into the accommodating space 15. The two crossbeams 142 respectively drive the two connected split walls 141 to rotate and fold, so that the top cover 12 is close to the chassis 11, until the two split walls 141 are folded together, thereby reducing the height of the container.

[0075] In this embodiment, the rotation axis of the split wall 141 and the top cover 12 or the chassis 11 is located inside the receiving space 15, and the rotation axis of the split wall 141 and the crossbeam 142 is located outside the receiving space 15.

[0076] Further, see Figures 10 to 12 A fixing frame 8 is fixed on the side of the split wall 141 facing the receiving space 15. The fixing frame 8 on the upper split wall 141 is rotatably connected to the top cover 12, and the fixing frame 8 on the lower split wall 141 is rotatably connected to the chassis 11, thereby indirectly realizing the rotatable connection between the split wall 141 and the top cover 12 or the chassis 11.

[0077] Further, see Figure 5 and Figure 10 The split wall 141 includes two frame rods 1411 spaced apart vertically, and the frame rods 1411 are arranged along a second horizontal direction 22. A corrugated plate 1412 is provided between the two frame rods 1411, and the corrugated plate 1412 is fixedly connected to the two frame rods 1411. The split wall 141 also includes a plurality of reinforcing frames 1413 arranged at intervals along the second horizontal direction 22. The reinforcing frames 1413 are inserted and fixed inside the two frame rods 1411, and the strength of the split wall 141 can be enhanced by the reinforcing frames 1413.

[0078] In some embodiments, see Figure 1 , Figure 6 and Figure 14 The side wall 14 of the box is provided with support columns 5 at both ends along the second horizontal direction 22. The support columns 5 are set separately, including a middle part 51, two segmented parts 52 and two outer ends 53.

[0079] The middle part 51 is fixedly connected to the crossbeam 142.

[0080] The two segmented parts 52 are fixedly connected to the two separate walls 141 respectively.

[0081] The two outer ends 53 are fixedly connected to the top cover 12 and the chassis 11, respectively.

[0082] When the two split walls 141 rotate and fold, the two split walls 141 can drive the two segmented parts 52 to fold.

[0083] Before the container is folded, the support column 5 is in an assembled state. The outer end 53, which is fixedly connected to the top cover 12, the segment 52, which is fixedly connected to the upper split wall 141, the middle part 51, which is fixedly connected to the crossbeam 142, the segment 52, which is fixedly connected to the lower split wall 141, and the outer end 53, which is fixedly connected to the chassis 11, are stacked sequentially from top to bottom. The chassis 11 supports the top cover 12 through the support column 5, thereby reducing the stress on the side walls 14 of the container. When the crossbeam 142 moves into the receiving space 15, the middle part 51 moves with the crossbeam 142, and the two split walls 141 can drive the two segment parts 52 to fold.

[0084] In this embodiment, the two support columns 5 are located on the opposite outer sides of the two box end walls 13 and abut against the two box end walls 13 respectively, thereby restricting the box end walls 13 from rotating away from the receiving space 15.

[0085] In some embodiments, see Figure 1 and Figure 2 The support column 5 is provided with a second locking component 6, which includes a second fixing member 61, a third fixing member 62, and a second sliding shaft 63.

[0086] The second fastener 61 is fixed to one of the segment portions 52.

[0087] The third fastener 62 is fixed to another segment 52.

[0088] The second sliding shaft 63 is slidably inserted into the second fixing member 61 and the third fixing member 62.

[0089] In this way, the support column 5 can remain in the combined state, and the crossbeam 142 drives the two split walls 141 to rotate. When the crossbeam 142 needs to drive the two split walls 141 to rotate, the second sliding shaft 63 is first slid out of the third fixing member 62.

[0090] Furthermore, the second locking assembly 6 may also include a second drive rod 64, which is perpendicular to the second sliding shaft 63 and has one end fixed to the second sliding shaft 63. Thus, the second drive rod 64 can drive the second sliding shaft 63 to slide.

[0091] Furthermore, the second fixing member 61 may include a plurality of second connecting portions 611, through which the second sliding shaft 63 slides. The plurality of second connecting portions 611 are divided into two groups, and the two groups of second connecting portions 611 are respectively located on both sides of the second drive rod 64 along the axial direction of the second sliding shaft 63. The sliding stroke of the second sliding shaft 63 is limited by the limiting of the second drive rod 64 by the two groups of second connecting portions 611.

[0092] Furthermore, the second fastener 61 is located above the third fastener 62 and is fixedly connected to the upper segment 52.

[0093] The second fixing member 61 is also provided with a second blocking part 612. The second blocking part 612 is located on one side of the radial direction of the second sliding shaft 63. The second blocking part 612 has a second blocking groove 6121 recessed towards the third fixing member 62. After the second sliding shaft 63 exits the third fixing member 62, the second driving rod 64 can enter the second blocking groove 6121 by sliding and rotating the second sliding shaft 63. In this way, the second sliding shaft 63 can be restricted from sliding into the third fixing member 62 again.

[0094] In some embodiments, see Figure 3 The segment 52 and the adjacent outer end 53 are provided with a latch lock 9. The latch assembly 91 and the base 92 of the latch lock 9 are respectively fixed to the segment 52 and the adjacent outer end 53. The movable hook 911 on the latch assembly 91 hooks into the slot on the base 92, so that the segment 52 and the adjacent outer end 53 can be locked together by the latch lock 9. In this way, the support column 5 can be kept in the assembled state.

[0095] In some embodiments, see Figure 2 , Figure 3 , Figure 15 and Figure 16 A guide unit 7 is provided on the surface of the support column 5 away from the side wall 14 of the box body. The guide unit 7 includes a first guide member 71.

[0096] The second guide member 72 has a plug-in portion 721 that is inserted into the first guide member 71 in a vertical direction. The plug-in portion 721 has a triangular block structure and its projection on the support column 5 is triangular. The first guide 71 and the second guide 72 can be fixedly mounted on the two segmented portions 52, respectively. Alternatively, the first guide 71 and the second guide 72 can be fixedly connected to the segmented portion 52 and the outer end portion 53 adjacent to the segmented portion 52, respectively. When the two segmented portions 52 are folded, the insertion portion 721 can be disengaged from the first guide 71.

[0097] When the two folded split walls 141 unfold and reset, the two segmented parts 52 that are fixedly connected to the two split walls 141 also unfold and reset, thereby restoring the support column 5. At this time, the insertion part 721 is re-inserted into the first guide member 71. Through the cooperation between the first guide member 71 and the insertion part 721, the support column 5 can be accurately restored to the combined state and the shaking of the combined support column 5 can be limited.

[0098] In this embodiment, there can be three guide units 7 on the support column 5. The first guide member 71 and the second guide member 72 in one guide unit 7 are respectively fixed on the two segmented portions 52. The two first guide members 71 in the other two guide units 7 are respectively fixed on the two segmented portions 52, and the two second guide members 72 are respectively fixed on the two outer ends 53.

[0099] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
