Description

Technical Field

[0001] The present invention relates to the technical field of containers, and particularly to a combined pallet box and a pallet box. Background Art

[0002] The pallet box, as a common logistics transportation container, has been widely used.

[0003] The foldable pallet box can be folded for transportation and storage when empty, increasing the transportation volume and reducing the warehouse floor area. It can be quickly assembled into a box when loading goods. The foldable pallet box is convenient for folding and assembling operations, has high efficiency and the components are not easily lost, which is convenient for logistics management. Therefore, it is one of the main structural forms of pallet boxes. Generally, a pallet box consists of a chassis, two end plates oppositely arranged on the end faces of the chassis, and two side plates oppositely arranged on the side faces of the chassis. The end side plates and between the end side plates and the chassis are connected by corresponding connecting mechanisms to form a complete box body.

[0004] Each user hopes to maximize the functions of the pallet box, make it multi-purpose and applicable in multiple fields. However, once the pallet box is made, its application field, load capacity, especially the internal dimensions are basically determined. Such a pallet box usually cannot meet the various needs of users.

[0005] Currently, it is mainly to design and manufacture larger-sized pallet boxes targeted according to the size of the user's goods. This increases the types of pallet boxes for the user. These pallet boxes are very troublesome in turnover, circulation and management. Various types of pallet boxes cannot be stacked on each other, and the components cannot be generally interchanged. All of these increase the user's costs.

[0006] Therefore, it is necessary to propose a combined pallet box and a pallet box to at least partially solve the above problems. Summary of the Invention

[0047] In the following description, numerous specific details are given to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the embodiments of the present invention may be practiced without one or more of these details. In other instances, in order to avoid confusion with the embodiments of the present invention, some well-known technical features are not described.

[0048] In order to thoroughly understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

[0049] The first embodiment

[0050] Reference Figures 1 to 10B , a pallet box according to the first embodiment of the present invention and a combined pallet box 100 formed by connecting the pallet boxes are described.

[0051] The pallet box mentioned herein is a kind of container, preferably a foldable container.

[0052] The box body 1 of the pallet box includes a chassis 50, side plates 51 (i.e., the first plates) provided at both ends of the box body in the transverse direction (i.e., the first horizontal direction), and end plates 52 (i.e., the second plates) provided at both ends of the box body in the longitudinal direction (i.e., the second horizontal direction). Among them, at least one of the side plates 51 can be detached from the box body, and the end plates 52 are foldably connected to the chassis 50. It should be noted that the "transverse direction" mentioned herein refers to the width direction of the box body, and the "longitudinal direction" refers to the length direction of the box body.

[0053] Two box bodies 1 with one side plate 51 detached are connected side by side along the transverse direction of the box body 1 to form a combined pallet box 100. It can be understood that the size of the combined pallet box 100 is approximately twice the size of the box body 1 of the pallet box.

[0054] Preferably, as Figure 3BAs shown, on the upper parts of the four corners of the tray box chassis, there are chassis columns extending upward, and on the lower parts of the four corners of the chassis, there are chassis feet. Threaded holes 13 are provided on the end faces (i.e., the second faces of the chassis columns) of the chassis columns, guide grooves 12 are provided on the side faces (i.e., the first faces of the chassis columns) of the chassis columns, and circular mating holes 11 are provided on the side faces (i.e., the first faces of the chassis feet) of the chassis feet. Also preferably, at the upper corner parts of the end plate 52, there are connection locks 20 for connection.

[0055] It should be noted that the "first face" of a certain component in the present invention refers to the face of the component facing the outside or inside of the box along the first horizontal direction, while the "second face" of a certain component refers to the face of the component facing the outside or inside of the box along the second horizontal direction.

[0056] Correspondingly, the first connection mechanism 2 (refer to Figure 4A , Figure 4B ) is installed on the upper parts of the end faces of the adjacent chassis columns of two boxes 1 for mating with the threaded holes 13. The first connection mechanism preferably includes a first connecting plate 201 and a first screw 202 extending inward along the longitudinal direction of the box 1 from the first connecting plate 201. When the first connection mechanism 2 connects two boxes 1, the threaded holes 13 are mated with the first screws 202, and the two chassis columns are connected together through the first connecting plate 201.

[0057] More preferably, in order to prevent the screws from being lost after the connecting plate is disassembled, the first connection mechanism 2 can be set as a screw anti - detachment structure, taking the first connection mechanism 2 as an example. As Figure 4B shown, the first connecting plate 201 is provided with a threaded hole M1, the root of the screw head of the first screw 202 is provided with a non - threaded smooth rod, the diameter φ1 of the smooth rod is smaller than the diameter φ2 of the thread of the first screw 202, and the length L1 of the smooth rod part is greater than the length L2 of the threaded hole of the first connecting plate 201. When the first screw 202 is screwed into the threaded hole of the first connecting plate 201 and the threaded hole of the first connecting plate 201 is located in the smooth rod part of the first screw 202, the first screw 202 is mated with the first connecting plate 201 to achieve the anti - detachment function. It can be understood that at this time, the screw is disengaged from the threaded connection with the connecting plate, and to detach the screw from the connecting plate, it is necessary to manually screw the screw into the threaded hole of the connecting plate again. When assembling or disassembling the combined tray box 100, during the process of connecting or disassembling the first connection mechanism 2, the threaded hole of the first connecting plate 201 is always located in the smooth rod part of the first screw 202, thus realizing screw anti - detachment (i.e., preventing the screw from detaching from the connecting plate and being lost).

[0058] Preferably, in order to increase the connection strength of the first connecting plate 201, hooks can be provided on both sides of the first connecting plate 201 (such as Figure 4B), a groove corresponding to the convex hook is provided on the chassis column. After the first screw 202 is firmly connected to the chassis column, the convex hook is engaged with the groove, increasing the tensile and compressive capacities of the first connecting plate 201 and at the same time preventing the first screw 202 from being damaged by excessive shear force.

[0059] Correspondingly, the second connecting mechanism 3 (refer to Figure 5 ) is provided on the side surfaces of the adjacent chassis feet of the two boxes 1 for cooperating with the mating holes 11. The second connecting mechanism 3 preferably includes a locking bolt 301, an adjusting bolt 302, an adjusting nut 303 and a locking nut 304. When the second connecting mechanism 3 connects the two boxes 1, the locking bolt 301 passes through the mating hole 11 on the chassis, the adjusting bolt 302 and the adjusting nut 303, and the two chassis are connected by the locking nut 304. After installation, the adjusting bolt 302 and the adjusting nut 303 are located between the adjacent chassis feet of the two boxes 1, and by adjustment, the adjusting bolt 302 and the adjusting nut 303 respectively abut against the adjacent chassis feet of the two boxes 1.

[0060] More preferably, a through hole extending along the axis of the adjusting bolt 302 and having a smooth inner surface is provided, and the body portion of the locking bolt 301 is sleeved in the through hole so that the adjusting bolt 302 can slide relative to the locking bolt 301 in its axial direction. In this embodiment, the adjusting bolt 302 and the adjusting nut 303 together form an adjusting assembly. It can be understood that the adjusting bolt 302 and the adjusting nut 303 cooperate to actually form a washer with adjustable thickness positioned between the two boxes 1.

[0061] Such a setting enables, when lifting two pallet boxes connected together by a device such as a forklift, especially when the pallet boxes are lifted in the folded and stacked state, the adjacent chassis feet of the two boxes 1 not to move closer to each other and cause the pallet boxes to arch and deform. The second connecting mechanism 3 is set as an adjustable structure instead of a fixed size because the chassis column and the chassis foot of the embodiment of the present invention are two parts, and there is a positioning error during production. After the first connecting mechanism 2 is connected, the distance between the adjacent chassis feet of the two boxes 1 is not necessarily fixed. Therefore, the adjustable structure can ensure that the adjusting bolt 302 and the adjusting nut 303 respectively abut against the adjacent chassis feet of the two boxes 1.

[0062] It can be understood that if the chassis uprights extend downward and the mating holes 11 are provided on the chassis uprights, and both the first connecting mechanism 2 and the second connecting mechanism 3 are connected to the chassis uprights, then a fixed structure can be provided to replace the adjustable second connecting mechanism 3. It should be noted that due to structural limitations in this embodiment, the height of the first connecting mechanism 2 is small, and only the upper part of the chassis uprights can be connected by two first screws 202. Therefore, the second connecting mechanism 3 is required to connect the lower parts of the four corners of the chassis. In other embodiments not shown, if the first connecting mechanism 2 is allowed to extend downward and the upper and lower parts of the chassis uprights can be connected by 4 first screws 202, then the second connecting mechanism 3 can also be cancelled when the connection strength is sufficient.

[0063] Preferably, a connecting upright 4 extending in the vertical direction is connected between the adjacent end plates 52 of the two boxes 1. Pin shafts 401 are provided on both sides of the lower end of the connecting upright 4 (refer to Figure 6B ). The pin shafts 401 are preferably integrally formed with the lower parts of the connecting upright 4 by processes such as casting. The pin shafts 401 can cooperate with the guide grooves 12 on the chassis to enable the pin shafts 401 to slide up and down and rotate in the guide grooves 12, thereby enabling the connecting upright 4 to be folded.

[0064] More preferably, a locking hole 402 is provided at the upper end of the connecting upright 4 (such as Figure 7A ). The locking hole 402 cooperates with the connecting locks 20 on the end plates 52 to realize the connection of the end plates 52 of the two boxes 1. Stacking blocks 403 can be provided at the top of the connecting upright 4 for stacking two pallet boxes on the combined pallet box 100 (that is, smaller pallet boxes can be stacked on the combined pallet box 100). When two connected large boxes in the assembled state are stacked, in addition to stacking at the four corners, stacking can also be carried out in the middle to bear the stacking force, improving the bearing capacity of the combined pallet box 100.

[0065] Preferably, the combined pallet box 100 further includes a sealing plate 5 located between the chassis 50 of the two boxes 1 and extending longitudinally (such as Figures 8A to 8B ). The sealing plate 5 straddles the side beams of the two chassis to block the gap between the two assembled boxes (the gap between the adjacent side beams of the chassis of the two boxes 1). The side beams of the chassis have a groove that is wider at the bottom and narrower at the top. The cross-section of the sealing plate 5 (such as Figure 8B ) corresponds to the groove of the side beam. The side of the sealing plate 5 cooperates with the side of the side beam of the chassis. After the two boxes 1 are connected, due to the wider bottom and narrower top, the sealing plate 5 cannot be disassembled, thereby also being able to play a firm connection role.

[0066] It can be understood that the closing plate 5, the connecting upright columns 4, the first connecting mechanism 2, and the second connecting mechanism 3 all constitute connecting components for connecting two boxes 1. The combined pallet box formed by the connecting components can also be folded, and its folding method is the same as that of the pallet box. First, unlock the locks 6 and 7, fold down the two sets of end plates 52 connected together, and then fold down the side plates 51. After folding, as shown in Figure 2A shown.

[0067] The combined pallet box 100 may further include a pull rod 8 connected between the tops of two connecting upright columns 4. Refer to Figure 9A and Figure 9B , the pull rod 8 preferably includes a bolt 801, a slot 802, an operating handle 803, and a pull rod body 804. The bolt 801 and the operating handle 803 are fixedly connected and can slide along the length direction of the pull rod body 804 (i.e., the longitudinal direction of the box 1). Through holes are provided in the upper part of the connecting upright column 4. During assembly, the width B of the pull rod body 804 is matched with the dimension B1 of the stacking block 403 at the upper end of the connecting upright column 4, the width C of the slot 802 is matched with the dimension C1 of the stacking block 403, and the dimension D of the bolt 801 is matched with the dimension D1 of the stacking block 403, so that the bolt 801 can penetrate through the through hole of the connecting upright column 4, thereby enabling the pull rod 8 to be completely locked with the connecting upright column 4 (refer to Figure 10B ).

[0068] More preferably, a spring can be provided to maintain the locked state. In the locked state, the spring is in a natural state or has a slight biasing force. When the operating handle 803 has a certain displacement relative to the locked state, the spring has a biasing force that biases the pull rod 8 towards the state where the pull rod 8 and the connecting upright column 4 are locked with each other. When the internal goods expand, this pull rod 8 can play a role in connecting and strengthening. When folding, this pull rod 8 can be folded together with the box and placed on the folded connecting upright column 4 and between adjacent chassis upright columns.

[0069] First, bring two boxes 1 with one of the side plates 51 removed close to each other, buckle the closing plate 5 into the groove of the side beam of the chassis, align the pin shaft 401 of the connecting upright column 4 with the guide groove 12, press the two boxes 1 tightly together so that the side beam of the chassis is engaged with the closing plate 5, and at the same time, the pin shaft 401 enters the guide groove 12. Subsequently, screw the first screw 202 of the first connecting mechanism 2 in a circular motion, and at the same time, the hook on the connecting plate 201 is engaged with the groove on the chassis upright column. Rotate the adjusting bolt 302 and the adjusting nut 303 to a smaller length and place them between the two chassis, insert the locking bolt 301, adjust the adjusting bolt 302 and the adjusting nut 303 so that they are in contact with the chassis of the two boxes 1 respectively, tighten the locking nut 304, and lock the lock 20 to complete the assembly of the combined pallet box 100. The disassembly process of the combined pallet box 100 is opposite to the above process and will not be elaborated here.

[0070] Second Embodiment

[0071] Figures 11 to 14B Shown is a pallet box according to a second embodiment of the present invention and a combined pallet box 200 formed by connecting pallet boxes. For the purpose of simplification, descriptions that are the same or similar to those of the first embodiment will be omitted.

[0072] In this embodiment, the end plate (i.e., the first plate) of the box body 31 of the pallet box is detachable, and the side plate (i.e., the second plate) is foldable. It can be understood that in this embodiment, the first horizontal direction is the longitudinal direction of the box body 31, and the second horizontal direction is the transverse direction of the box body 31.

[0073] Two box bodies 31 with one end plate removed (such as Figure 11 ) are connected side by side along the longitudinal direction of the box body 31. A second threaded hole 41 (i.e., an embodiment of the threaded hole) for connecting the box body is provided on the side surface of the chassis column (i.e., the second surface of the chassis column), and a third threaded hole 42 for connection is provided on the second surface at the upper corner of the side plate.

[0074] Correspondingly, a third connecting mechanism 32 (i.e., another embodiment of the first connecting mechanism) is provided on the side surfaces of the adjacent chassis columns and chassis feet of the two box bodies 31, and is specifically composed of a second connecting plate 43 and a second screw 44. When connecting the two box bodies 31, the second screw 44 cooperates with the second threaded hole 41, and the chassis of the two box bodies 31 is connected together through the second connecting plate 43.

[0075] Similarly and correspondingly, a fourth connecting mechanism 33 (i.e., yet another embodiment of the first connecting mechanism) is provided on the outer surface at the upper corner of the adjacent side plates of the two box bodies 31, and is specifically composed of a third connecting plate 45 and a third screw 46. When connecting the two box bodies 31, the third screw 46 cooperates with the third threaded hole 42 to connect the adjacent side plates of the two box bodies 31. The folding method of the box body after such connection is the same as that of the original box body. First, unlock the locks 34 and 35 on the end plates and fold down the two end plates, and then fold down the two groups of connected side plates in sequence.

[0076] To increase the connection strength between the second connecting plate 43 and the third connecting plate 45, hooks similar in structure to the first connecting plate 201 can be provided on the second connecting plate 43 and the third connecting plate 45, and grooves corresponding to the hooks can be provided on the chassis uprights and the upper corners of the side plates (side plate stacking members). The connection form and function of the hooks and the grooves are similar to those of the first connecting plate 201. Among them, the groove corresponding to the hook of the second connecting plate 43 can utilize the guide groove 12. In addition, vertical ribs can be provided in the middle of the second connecting plate 43 and the third connecting plate 45. The vertical ribs extend in the vertical direction and are used to connect the two boxes 31 and separate the two boxes 31 in time to avoid difficulties in connecting the second connecting plate 43 and the third connecting plate 45 to the two boxes 31 due to processing and welding errors of the chassis end side beams, chassis uprights, chassis feet, and side plate edge uprights (for example, due to processing and welding errors, the two boxes 31 cannot be closely adjacent, and the screws and threaded holes cannot be aligned). Another function of the vertical ribs is to prevent the two boxes 31 from being forced to approach when the large box connected together is forklifted, causing deformation of the box body.

[0077] Preferably, screw anti-loosening devices similar to those of the first connecting mechanism 2 can also be provided on the third connecting mechanism 32 and the fourth connecting mechanism 33.

[0078] The third embodiment

[0079] Figure 15 The pallet box according to the third embodiment of the present invention and the combined pallet box 300 formed by connecting the pallet boxes are shown. For the purpose of simplification, the description of the same or similar parts between this embodiment and the first embodiment will be omitted.

[0080] In this embodiment, the combined pallet box 300 is formed by connecting three pallet boxes in sequence along the transverse direction (i.e., the first horizontal direction) of the box body of the pallet box. The side plates (i.e., the first plates) of the pallet box are detachable and the end plates (i.e., the second plates) are foldable.

[0081] Furthermore, according to actual needs, more than three pallet boxes can be connected in sequence to form a larger combined pallet box to meet different needs of users.
