Description

Technical Field

[0001] The invention relates to the technical field of foldable transfer boxes, and in particular to a reusable transfer box with a high folding ratio. Background Art

[0002] Agricultural products are mainly loaded in plastic baskets or transfer boxes from the field to the retail consumer end. For most cold chain transportation links, the existing agricultural product logistics transfer boxes are mostly one-piece foam plastic boxes and folding transfer boxes. Compared with one-piece foam plastic boxes, folding transfer boxes have more advantages. Not only are they reusable, but they can also be folded when recycled, greatly reducing the space they occupy.

[0003] The existing foldable transfer box generally includes two short side panels, two long side panels and a bottom panel, and the short side panels and the long side panels are both rotated at the ends of the bottom panel. Fig. 9 As shown, the utility model patent with Chinese announcement number CN218259247U discloses "a foldable agricultural product logistics transfer box", whose short side panels and long side panels have rounded corners at the bottom and are rotatably arranged at the end of the bottom plate, and the rotation axis of the short side panel is higher than the rotation axis of the long side panel. After folding, there is a certain gap between the bottom of the long side panel and the bottom plate, and the waste leaves of the agricultural products can easily enter the surface of the bottom plate, which needs to be cleaned after the subsequent transfer box is unfolded; at the same time, the bottom of the long side panel is exposed to the outside and is also easily damaged, resulting in an inability to open normally.

[0035] In view of the shortcomings of the prior art, this embodiment provides a reusable high folding ratio transport box, which can be specifically referred to as follows:

[0036] As attached Figure 1, Attachment Figure 2 , Attachment Figure 3 And attached Fig. 9 As shown, a reusable high folding ratio transport box comprises a bottom plate 1, two short side plates 2 and two long side plates 3. Two short side plates 2 are rotatably provided at both lateral ends of the bottom plate 1, and two long side plates 3 are rotatably provided at both longitudinal ends of the bottom plate 1. The two ends of the short side plates 2 are respectively matched with the two long side plates 3 and are arranged perpendicular to each other. The longitudinal ends of the two short side plates 2 on the opposite sides are respectively provided with wedge-shaped grooves 21, and the lateral ends of the two long side plates 3 on the opposite sides are respectively provided with wedge-shaped blocks 31. The wedge blocks 31 correspond to the wedge-shaped grooves 21 one by one and cooperate with each other, so that the short side plates 2 can be connected with the adjacent ones. The long side panels 3 are connected, and eccentric shafts 22 are arranged on both sides of the short side panels 2. The eccentric shafts 22 are rotatably arranged on the bottom panel 1. The distance between the axis of the eccentric shaft 22 and the side wall of the short side panel 2 close to the center of the bottom panel 1 and the bottom wall of the short side panel 2 is the same, and the distance is smaller than the distance between the axis of the eccentric shaft 22 and the side wall of the short side panel 2 far from the center of the bottom panel 1, so that when the short side panel 2 is perpendicular to the bottom panel 1, the outer side wall of the short side panel 2 and the side wall of the bottom panel 1 are in the same plane, and when the short side panel 2 is folded, there is a certain distance between the bottom wall of the short side panel 2 and the side wall of the bottom panel 1;

[0037] The cooperation between the wedge block 31 and the wedge groove 21 can facilitate the quick installation of the transfer box. At the same time, by arranging the eccentric shaft 22 on the short side panel 2, a certain distance can be formed between the bottom wall of the short side panel 2 and the side wall of the bottom panel 1 when folded. After the long side panel 3 is folded, the side wall of the wedge block 31 of the long side panel 3 abuts against the surface of the bottom panel 1 to cover the short side panel 2. The short side panel 2 is closed and protected by the protruding wedge block 31, which further prevents the bottom of the short side panel 2 from being damaged or waste leaves and other debris from entering from the gap between the rounded corner of the bottom of the short side panel 2 and the bottom panel 1.

[0038] Specifically, the wedge-shaped grooves 21 of the short side panels 2 are engaged with the wedge-shaped blocks 31 of the long side panels 3, so that the short side panels 2 and the long side panels 3 are connected together and fixed to a certain extent; the rotation axis of the long side panels 3 is higher than the rotation axis of the short side panels 2, so that the long side panels 3 can cover the short side panels 2 when folded; when the transfer box is changed from the unfolded state to the folded state, the short side panels 2 can be disengaged from the long side panels 3 first, and the short side panels 2 can be rotated towards each other and placed on the surface of the bottom plate 1 and parallel to the surface of the bottom plate 1. After the short side panels 2 are rotated, the bottom wall of the short side panels 2 is parallel to the side walls of the bottom plate 1, and then Then the two long side panels 3 are rotated toward each other, the surfaces of the long side panels 3 are abutted against the surfaces of the short side panels 2, and the protruding wedge blocks 31 of the long side panels 3 are placed in the gap between the bottom wall of the short side panels 2 and the side walls of the bottom panel 1. The wedge blocks 31 can be set to a protruding distance. After folding, the side walls of the wedge blocks 31 abut against the surface of the bottom panel 1, and cover and wrap the short side panels 2; at the same time, through the setting of the eccentric shaft 22, the two short side panels 2 can be brought closer to the center of the bottom panel 1, and the short side panels 2 can be wrapped by the wedge blocks 31, thereby further reducing the redundant box space after folding, which can effectively improve the folding ratio of the transfer box.

[0039] In this embodiment, the length × width × height of the transfer box before folding is 600mm × 500mm × 330mm, and the size after folding is 600mm × 500mm × 105mm; the folding ratio of the transfer box (height ratio before and after folding) reaches 3.14, thereby achieving a high folding ratio of the transfer box.

[0040] In one embodiment of the present application, as shown in the attached Figure 4 As shown, a plurality of first rotating blocks 11 are respectively arranged at the lateral ends of the bottom plate 1, and the plurality of first rotating blocks 11 are arranged on the surface of the bottom plate 1 and are arranged at intervals to form a plurality of first rotating grooves 12. A second rotating block 23 is arranged at the bottom of the short side plate 2, and an eccentric shaft 22 is arranged at both ends of the second rotating block 23. The eccentric shaft 22 is located on one side of the central axis of the side wall of the short side plate 2, thereby deviating from the central axis of the short side plate 2. The eccentric shaft 22 is rotatably matched with the rotating block, and a step 24 is arranged on one side of the first rotating block 11 and the second rotating block 23. When the short side plate 2 is folded, the second rotating block 2 The step 24 of the wedge block 3 overlaps with the step 24 of the first rotating block 11 to form a whole step 24; a groove 32 is provided at one end of the wedge block 31. When the wedge block 31 is folded along with the long side panel 3, the groove 32 of the wedge block 31 cooperates with the steps 24 of the first rotating block 11 and the second rotating block 23, thereby further reducing the redundant box space; at the same time, through the engagement of the groove 32 with the step 24, the stability of the short side panel 2 under the cover of the long side panel 3 can be further guaranteed, and the short side panel 2 can be prevented from shaking and colliding due to vibration, thereby causing damage to the long side panel 3 or the short side panel 2.

[0041] In this embodiment, as shown in the attached Figure 2 , Attachment Figure 4 and attached Figure 5 As shown, the top inner side of the first rotating block 11 is provided with a rounded corner, and the bottom inner side of the second rotating block 23 is provided with a rounded corner to facilitate the relative rotation of the second rotating block 23 and the first rotating block 11; at the same time, the bottom outer side of the second rotating block 23 is a right angle, which is used to limit the rotation angle of the second rotating block 23, so that the maximum angle of the second rotating block 23 is 90 degrees, and it is in a vertical state with the base plate 1.

[0042] In this embodiment, as shown in the attached Figure 4 As shown, baffles 13 are respectively provided at the two lateral ends of the bottom plate 1, and the two baffles 13 are respectively located on the opposite sides of the first rotating block 11 on the lateral sides of the bottom plate 1, that is, the first rotating block 11 is located between the two baffles 13. Through the arrangement of the two baffles 13, a cavity with an opening facing upward can be formed on the surface of the bottom plate 1, and after the long side plate 3 is folded, the side wall of the wedge block 31 and the top wall of the baffle 13 are supported against each other, thereby achieving a sealing effect; at the same time, due to the arrangement of the baffle 13, the connection between the wedge block 31 and the baffle 13 is higher than the surface of the bottom plate 1, thereby reducing the entry of debris such as waste leaves, and at the same time, the inner side of the connection between the wedge block 31 and the baffle 13 is the side wall of the first rotating block 11 and the second rotating block 23, thereby further sealing and blocking the entry of debris, and when unfolded, the baffle 13 supports and seals the bottom of the short side plate 2.

[0043] In one embodiment of the present application, as shown in the attached Figure 2 and attached Figure 3 As shown, a plurality of mutually symmetrical inclined fixing blocks 25 are provided on the side wall of the wedge-shaped groove 21, and a plurality of mutually symmetrical inclined fixing grooves 33 are provided on the side wall of the wedge-shaped block 31. The inclined fixing blocks 25 correspond to the inclined fixing grooves 33 one by one and cooperate with each other. When the transfer box is unfolded, the long side panel 3 is first rotated 90 degrees to be in a vertical state with the bottom plate 1, and then the short side panel 2 is rotated. While rotating, the inclined fixing blocks 25 of the short side panel 2 are inserted into the inclined fixing grooves 33 of the wedge-shaped block 31 to fix the short side panel 2 and the long side panel 3.

[0044] In this embodiment, the top of the wedge-shaped groove 21 is an inclined surface, and the top of the wedge block 31 is provided with a chamfer to match the inclined surface of the wedge-shaped groove 21, so that the short side plate 2 and the long side plate 3 can be better fixed and the stability of the connection can be increased.

[0045] In this embodiment, there are four inclined fixing blocks 25 of the wedge groove 21 and four inclined fixing grooves 33 of the wedge block 31, two of which are inclined downward and two are inclined upward, and are arranged symmetrically. Through the different inclination directions of the inclined fixing blocks 25, the force direction thereof can be adjusted to avoid separation due to unidirectional force.

[0046] In one embodiment of the present application, as shown in the attached Figure 1 and attached Figure 3 As shown, a plurality of first connecting grooves 34 are arranged on the top of the long side plate 3, and the first connecting grooves 34 penetrate the side walls of the long side plate 3. A double rotating shaft connecting member 4 is rotatably arranged in the first connecting grooves 34, and a cover plate 5 is rotatably arranged on one end of the double rotating shaft connecting member 4 away from the long side plate 3, and the cover plate 5 can cover the top opening of the transfer box through the double rotating shaft connecting member 4.

[0047] In this embodiment, as shown in the attached Figure 6 As shown, rounded corners are provided at both ends of the dual-rotation axis connector 4 to facilitate the rotation of the dual-rotation axis connector 4 and the first connection groove 34 and the cover plate 5; specifically, a second connection groove 55 is provided on one side of the cover plate 5, and the dual-rotation axis connector 4 rotates with the second connection groove 55.

[0048] Furthermore, a support block is provided on the inner side of the bottom of the double-rotating-axis connector 4, and the bottom wall of the support block is a horizontal plane, so as to limit the rotation angle of the double-rotating-axis connector 4 in the first connecting groove 34 toward the inside of the transfer box, so as to avoid the double-rotating-axis connector 4 from rotating too much, causing extrusion and damage to the cover plate 5, the long side plate 3 and the short side plate 2.

[0049] Furthermore, a rotating shaft is provided in the second connecting groove 55, and the rotating shaft is rotatably arranged with the rotating hole of the double rotating shaft connecting member 4. Specifically, the diameter of the rotating shaft is smaller than the diameter of the rotating hole, so that the cover plate 5 can be pulled upwards and a certain gap appears with the top of the long side plate 3, which is convenient for the cover plate 5 to rotate. The inner side of the bottom of the cover plate 5 is a right angle, and no rounded corners are set, which is also for the convenience of sealing the opening of the transfer box.

[0050] In this embodiment, as shown in the attached Figure 1 As shown, a Z-shaped groove 51 and a Z-shaped block 52 are respectively provided on the opposite sides of the two cover plates 5; when the transfer box is in an unfolded state and the opening needs to be closed, the two cover plates 5 can be rotated to the top of the opening and the Z-shaped block 52 can be snapped into the Z-shaped groove 51, so that the two cover plates 5 can be fixed and the opening of the transfer box can be closed.

[0051] In this embodiment, two recessed grooves 53 are provided on the opposite sides of the two cover plates 5, and the two recessed grooves 53 are respectively located at the lateral ends of the cover plates 5, and the two recessed grooves 53 on the same side of the two cover plates 5 cooperate with each other to form buckle grooves, and buckles 6 are rotatably provided on the opposite sides of the two short side plates 2, and the buckles 6 cooperate with the buckle grooves. The two cover plates 5 can be fixed to the corresponding short side plates 2 through the buckles 6 to prevent the two cover plates 5 from being separated due to external force, causing the opening of the transfer box to open and causing damage to the agricultural products inside.

[0052] In this embodiment, as shown in the attached Figure 1As shown, the buckle 6 is a prior art, and the buckle 6 includes a first rotating plate and a second rotating plate. The first rotating plate is rotatably set on the short side plate 2, and one end of the first rotating plate is rotatably connected to the second rotating plate. The rotating axis of the second rotating plate is located in the middle position of the side wall of the first rotating plate, and a notch is provided at one end of the second rotating plate away from the first rotating plate. The length of the first rotating plate and the second rotating plate is greater than the distance between the rotating axis of the first rotating plate and the top wall of the cover plate 5; specifically, the first rotating plate can be rotated to rotate the notch of the second rotating plate to the top of the buckle groove, and then the first rotating plate can be pressed to make the second rotating plate move downward and be clamped on the buckle groove for fixing.

[0053] In this embodiment, as shown in the attached Figure 3 As shown, two placement grooves 35 are provided on the opposite sides of the two long side panels 3, and the two placement grooves 35 are respectively located at the two ends of the long side panels 3 in the horizontal direction. The two placement grooves 35 on the same side of the two long side panels 3 can cooperate with each other to form a square groove, and the square groove cooperates with the buckle 6; specifically, when the transfer box is folded, the two long side panels 3 rotate in the opposite directions until the top walls of the two long side panels 3 abut against each other and cover the surface of the short side panel 2. At this time, the two placement grooves 35 on the same side of the two long side panels 3 correspond to each other, and the two placement grooves 35 cooperate to form a groove body with an opening;

[0054] Two buckles 6 are provided on the opposite sides of the short side panels 2, and the buckles 6 protrude from the surface of the short side panels 2. When the short side panels 2 are rotated and folded, the buckles 6 will also protrude from the surface of the short side panels 2. If the long side panels 3 are directly folded, the side walls of the long side panels 3 will be supported on the buckles 6, thereby forming a gap between the side walls of the long side panels 3 and the side walls of the short side panels 2, resulting in a smaller folding ratio of the transfer box; and the present application provides placement grooves 35 on the side walls of the two long side panels 3, and when folded, the corresponding two placement grooves 35 cooperate with each other to form a square groove for wrapping the buckles 6, so that the side walls of the long side panels 3 are not affected by the buckles 6, but directly abut against the surface of the short side panels 2, thereby ensuring the maximum folding ratio of the transfer box.

[0055] In one embodiment of the present application, an opening groove 54 is provided on one side of the cover plate 5 facing the interior of the transfer box, and the opening groove 54 is used to install a sensor; specifically, the sensor can be a temperature and humidity sensor, a positioning sensor or a Bluetooth communication sensor, or a combination of multiple sensors, for temperature and humidity detection, positioning and communication of the transfer box.

[0056] In one embodiment of the present application, as shown in the attached Figure 1 and attached Figure 2As shown, Z-shaped positioning blocks 26 are respectively provided at the two longitudinal ends of the top of the two short side panels 2, and Z-shaped positioning grooves 56 are respectively provided at the two lateral ends of the cover plate 5. When the two cover plates 5 block the opening of the transfer box, the Z-shaped positioning grooves 56 cooperate with the Z-shaped positioning blocks 26 to position and limit the cover plate 5, and also increase the stability and sealing between the short side panels 2 and the cover plate 5.

[0057] In one embodiment of the present application, raised support plates 14 are respectively provided at both longitudinal ends of the bottom plate 1, and the two ends of the two support plates 14 are respectively connected to the baffle 13, so that the surface of the bottom plate 1 is enclosed into a cavity with an opening facing upward, and the height of the support plate 14 is higher than the height of the baffle 13, and a plurality of third connecting grooves 15 are opened on the top of the support plate 14, and a third rotating block 36 is provided at the bottom of the long side plate 3, and the third rotating block 36 is rotatably set in the third connecting groove 15, and the long side plate 3 can be folded by rotating the third rotating block 36 in the third connecting groove 15.

[0058] In this embodiment, a rounded corner is provided on the inner side of the top of the support plate 14, and a rounded corner is also provided on the inner side of the bottom of the third rotating block 36. When the long side panel 3 is folded, the bottom wall of the long side panel 3 can rotate along the rounded corner of the support plate 14, and the rounded corner of the bottom of the third rotating block 36 can rotate in the third connecting groove 15.

[0059] In one embodiment of the present application, a transport groove 7 is provided on the opposite side of the two short side panels 2 and the opposite side of the two long side panels 3. The transport groove 7 can be used to engage with external auxiliary equipment and manual fingers to facilitate the transport of the transfer box.

[0060] In this embodiment, the bottom wall of the base plate 1 is provided with four arcuate grooves 8, and the four arcuate grooves 8 are respectively distributed in the middle positions of the four side walls of the base plate 1. The arrangement of the arcuate grooves 8 facilitates the transportation of the transfer box in a folded state.

[0061] In this embodiment, the bottom plate 1 , the two short side plates 2 , the two long side plates 3 and the two cover plates 5 are all made of EPP material and can undergo slight elastic deformation.

[0062] In this embodiment, the length × width of the bottom plate 1 is 600mm × 500mm, and the two short sides of the bottom plate 1 are provided with a first rotating block 11, and the matching baffle 13 is in a three-layer stepped shape, and when unfolded, the baffle 13 supports and seals the bottom of the short side plate 2; the length × width of the short side plate 2 is 500mm × 330mm, and the thickness is 30mm. The bottom of the short side plate 2 is provided with a second rotating block 23, and the second rotating block 23 is in a one-layer stepped shape; the length × width of the long side plate 3 is 600mm × 330mm, and the thickness is 30mm.

[0063] Working principle:

[0064] In the initial state, if attached Figure 8 As shown, the transfer box is generally in a folded state. When the transfer box needs to be unfolded, the two cover plates 5 can be pulled to lift the two cover plates 5 and drive the third rotating block 36 of the long side plate 3 to rotate in the third connecting groove 15 until the long side plate 3 rotates 90 degrees and is in a vertical state with the bottom plate 1. At this time, the two cover plates 5 can be placed on the opposite sides of the two long side plates 3 under the action of the double rotating shaft connecting member 4 and are in a parallel state with the long side plates 3. Then, by pulling the buckle 6, the second rotating block 36 of the short side plate 2 is 23 rotates in the first connecting groove 34. As the short side plate 2 rotates, the wedge-shaped groove 21 on one side of the short side plate 2 abuts against the wedge-shaped block 31 of the long side plate 3. At the same time, as the rotation continues, the wedge-shaped groove 21 and the wedge-shaped block 31 can be clamped with each other, and the inclined fixing block 25 in the wedge-shaped groove 21 can also be clamped with the inclined fixing groove 33 in the wedge-shaped block 31, so that the short side plate 2 and the long side plate 3 are fixed to prevent the short side plate 2 or the long side plate 3 from rotating during loading. After unfolding (such as the attached Figure 1 As shown in the figure, agricultural products can be loaded. After loading, the cover plate 5 can be rotated to the open top of the transfer box and fixed under the action of the Z-shaped grooves 51 and the Z-shaped blocks 52 of the two cover plates 5. At the same time, the Z-shaped positioning blocks 26 on the short side plates 2 are also engaged with the Z-shaped positioning grooves 56 on the cover plate 5 to further strengthen the connection between the cover plate 5 and the short side plates 2. Finally, the buckle 6 can be matched with the buckle groove (as shown in the figure). Figure 7 As shown), the loading work is completed, and manual or external auxiliary equipment can be connected to the transport slot 7 for transport;

[0065] When it is needed to be recycled and reused after use, the cover plate 5 can be opened first and rotated to one side of the long side plate 3, and then the short side plate 2 can be detached from the long side plate 3. The two short side plates 2 can be rotated toward each other and the short side plates 2 can be rotated to the surface of the bottom plate 1. Then, the two long side plates 3 can be rotated toward each other so that the long side plates 3 abut against the surface of the short side plates 2. At the same time, the groove 32 on the wedge block 31 is engaged with the step 24 formed by the first rotating block 11 and the second rotating block 23, and the side wall of the wedge block 31 abuts against the baffle 13 of the bottom plate 1, so as to achieve covering and sealing of the short side plates 2.
