Description

Technical Field

[0001] This invention relates to the field of logistics and transportation technology, specifically a cold chain intelligent logistics transportation box. Background Technology

[0002] Cold chain logistics transport boxes are mainly used to provide a relatively stable low-temperature environment for fresh products during transportation, turnover, and temporary storage. For fresh fruits such as lychees, which are easily affected by mechanical forces, in addition to temperature conditions, compression, collisions, and repeated vibrations during transportation can also affect the integrity of the fruit. When transported in ordinary boxes, the fruit is usually placed together in the same area. During vehicle vibration, stacking, and loading and unloading, the fruit is prone to relative movement and localized pressure, which increases the possibility of damage to the peel or compression of the flesh.

[0003] Existing cold chain packaging typically cools goods by placing ice packs, cold storage media, or other cold sources inside the container. However, the cold source structure and the cargo-bearing structure are often separate. For fresh fruit that needs to be individually supported, simply setting up a low-temperature cold source cannot solve the problem of the fruit being squeezed together, while using only a partition structure makes it difficult to ensure heat exchange between the cold source and the fruit. In addition, when the cooling medium is lifted and unloaded along with the loading components, it increases the operational load; after the coolant is transferred between different storage areas, its liquid level and effective occupied space change, which may also affect the working condition of local heat exchange structures. Summary of the Invention

[0004] The purpose of this invention is to provide a cold chain intelligent logistics transport box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A cold chain intelligent logistics transport box includes a bottom plate, a horizontal plate, and a storage cylinder. A storage space is formed between the bottom plate and the horizontal plate. A through hole communicating with the storage space is opened on the horizontal plate. The storage cylinder is movably inserted through the through hole. The storage cylinder is provided with a liquid storage space for containing coolant and a cylindrical block. A first annular plate is provided on the outer periphery of the cylindrical block. A loading groove is provided on the first annular plate. A cavity is formed inside the cylindrical block, and a protective plate is movably disposed inside the cavity. A through hole is opened on the cylindrical block that communicates with the cavity and allows the protective plate to pass through. The protective plate can move between a first position where it is housed in the cavity and a second position where it extends through the through hole to the top of the loading trough.

[0006] Specifically, a storage box is provided at the through hole of the horizontal plate, the storage box is fixedly connected to the horizontal plate, and the liquid storage space is connected to the storage box through a flexible telescopic tube.

[0007] Specifically, a U-shaped plate is fixedly connected to the storage box, a groove is provided in the U-shaped plate, a sliding plate is slidably connected in the groove, and the first support rod is fixedly connected to the sliding plate; An adjusting bolt is rotatably connected to the sliding plate, and the adjusting bolt is threadedly connected to the U-shaped plate; A limiting groove is formed in the first bearing rod, and a limiting block is connected to the second bearing rod. The limiting block is movably disposed in the limiting groove.

[0008] Specifically, the first support rod is provided with a shock-absorbing column; the second support rod is provided with a groove, and a shock-absorbing spring is provided in the groove. The shock-absorbing spring is connected to a support plate, and the support plate extends at least partially out of the groove.

[0009] Specifically, the first annular plate is detachably connected to the cylindrical block; The first annular plate has a receiving groove on its side wall, and a spring and a insert plate are provided in the receiving groove. The spring acts on the insert plate, and the insert plate can be inserted into the cylindrical block. A connecting plate is provided on the cylindrical block, and the connecting plate, the insert plate, and the first annular plate are connected by fixing bolts.

[0010] Specifically, a circular plate is rotatably disposed inside the cavity, a second annular plate is disposed on the outer periphery of the circular plate, a slide rail is disposed on the second annular plate, and a slider is slidably connected on the slide rail; The slider is connected to the circular plate by a connecting rod, and the slider is connected to the protective plate by a connecting rod. The circular plate is connected to the rotating rod, and the rotating rod is provided with a rotating block for driving the circular plate to rotate.

[0011] Specifically, a heat-conducting plate is provided on the side of the protective plate facing the loading trough, and a heat-conducting block is provided on the heat-conducting plate.

[0012] Specifically, the inner wall of the storage cylinder is provided with heat dissipation holes, and an arc-shaped heat-conducting plate is provided at the heat dissipation holes; A first elastic rubber column is connected to the arc-shaped heat-conducting plate, and a movable plate is connected to the first elastic rubber column. A blocking block is provided on the movable plate, and the blocking block cooperates with the heat dissipation hole. The heat-conducting block is disposed opposite to the blocking block, and can push the blocking block to change its position relative to the heat dissipation hole as the protective plate moves.

[0013] Specifically, the side wall of the liquid storage space is provided with a liquid volume compensation component, which includes a movable plate, an elastic reset member, and a liquid pushing part disposed on the movable plate; The movable plate is sealed and movable with the liquid storage space. The elastic reset member is used to apply a reset force to the movable plate, so that the movable plate drives the liquid pushing part to move, thereby changing the effective volume of the liquid storage space.

[0014] Specifically, the side wall of the liquid storage space is provided with a storage groove, and the movable plate is slidably connected to the storage groove in a sealed manner; The elastic reset component is a second elastic rubber column disposed in the storage groove, with one end of the second elastic rubber column connected to the storage groove and the other end connected to the movable plate; The liquid-pushing part is a liquid-pushing block that is fixedly connected to the movable plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting up a separating load-bearing structure and a movable protective structure, allows fruits to be placed separately and restrained, reducing relative displacement and mutual compression caused by vibration during transportation. Simultaneously, the flow of coolant between different storage areas achieves cooling during transportation and reduces the load weight during loading or lifting. The protective structure and heat exchange structure work together to form corresponding heat exchange pathways at the protected locations, and automatic reset is achieved through an elastic reset structure. The volume compensation structure set in the storage area can adjust the effective volume according to changes in the coolant state, keeping the coolant in a relatively stable working state. Furthermore, the detachable fruit-bearing structure facilitates loading, unloading, and cleaning, and, together with the support and shock-absorbing structures, further improves stability and protective effect during transportation.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-12 As shown in the embodiment of the present invention, a cold chain intelligent logistics transport box includes a base plate 1 and a horizontal plate 2 disposed above the base plate 1; a storage space 3 is reserved between the base plate 1 and the horizontal plate 2, a through hole is provided on the horizontal plate 2, a liquid storage box 4 is fixedly connected in the through hole, a U-shaped support frame 5 is fixedly connected on the liquid storage box 4, a first support rod 6 is adjustablely connected in the U-shaped support frame 5, and a second support rod 7 is movably connected in the first support rod 6.

[0020] Furthermore, a fruit receiving cylinder 8 is movably installed inside the through hole. A coolant cavity 9 is opened inside the fruit receiving cylinder 8, which is connected to the liquid storage box 4. A central support column 47 is installed inside the fruit receiving cylinder 8. An annular support plate 10 is detachably connected to the outer circumferential wall of the central support column 47. A fruit receiving groove 11 is opened on the upper surface of the annular support plate 10 facing downward. A cavity is opened inside the central support column 47. A limiting protective plate 12 is movably connected inside the cavity. The limiting protective plate 12 cooperates with the fruit receiving groove 11.

[0021] In the above embodiment, the base plate 1 and the horizontal plate 2 are fixedly connected by a support block 13, which enables the horizontal plate 2 to be fixedly connected above the base plate 1.

[0022] Specifically, a sliding groove 14 is provided inside the U-shaped support frame 5, and a sliding plate 15 is slidably connected inside the sliding groove 14. The sliding plate 15 is fixedly connected to the first support rod 6. An adjusting bolt 16 is rotatably connected to the side wall of the sliding plate 15. The adjusting bolt 16 is threadedly connected to the U-shaped support frame 5. The operator manually rotates the adjusting bolt 16, and the sliding plate 15 moves during the rotation of the adjusting bolt 16, thereby adjusting the position of the first support rod 6.

[0023] Furthermore, a limiting groove 17 is provided in the first support rod 6, and a limiting block 18 is movably connected in the limiting groove 17. The limiting block 18 is fixedly connected to the second support rod 7. The limiting groove 17 facilitates the movement of the limiting block 18 within the first support rod 6, thereby enabling the extension and retraction of the second support rod 7 relative to the first support rod 6.

[0024] In one optional embodiment, a shock-absorbing column 19 is fixedly connected to the first support rod 6. The shock-absorbing column 19 is made of rubber elastic material. When the bottom end of the fruit container 8 is located on the shock-absorbing column 19, the shock-absorbing column 19 realizes the shock absorption effect on the fruit container 8.

[0025] Furthermore, a groove is provided on the second support rod 7, and a shock-absorbing spring 20 is fixedly connected in the groove. A support plate 21 is fixedly connected to the upper end of the shock-absorbing spring 20. The upper end of the support plate 21 passes through the groove and is located above the second support rod 7. When the fruit container 8 is located above the second support rod 7 and the support plate 21 is located below the fruit container 8, the shock-absorbing spring 20 is used to dampen the shock of the fruit container 8.

[0026] In the above embodiment, the coolant chamber 9 and the coolant reservoir 4 are connected by a flexible telescopic tube 22, which facilitates the mutual flow of coolant in the coolant chamber 9 and coolant in the coolant reservoir 4.

[0027] Specifically, a receiving groove is provided on the side wall of the annular bearing plate 10, and a spring 23 is fixedly connected in the receiving groove. One end of the spring 23 is fixedly connected to an insert plate 24, and one end of the insert plate 24 is inserted into the central support column 47. A connecting plate 25 is fixedly connected to the central support column 47, and the connecting plate 25, the insert plate 24 and the annular bearing plate 10 are connected by fixing bolts 26.

[0028] Based on the above structure, when it is necessary to remove the annular bearing plate 10 from the central support column 47, the operator manually rotates the fixing bolt 26. When the fixing bolt 26 is detached from the connecting plate 25, the insert plate 24, and the annular bearing plate 10, the operator manually pushes the insert plate 24 to move the insert plate 24. Then, the annular bearing plate 10 is moved upward to detach it from the central support column 47. When it is necessary to install the annular bearing plate 10 on the central support column 47, the operator manually pushes the insert plate 24 and then places the annular bearing plate 10 into the central support column 47 from top to bottom. The operator manually loosens the insert plate 24. When one end of the insert plate 24 is inserted into the central support column 47, the operator then manually rotates the fixing bolt 26 to thread one end of the fixing bolt 26 onto the connecting plate 25, the insert plate 24, and the annular bearing plate 10, thus achieving the connection between the annular bearing plate 10 and the central support column 47.

[0029] Furthermore, a circular plate 27 is rotatably connected inside the cavity, and a second annular plate 28 is fixedly connected to the outer circumference of the circular plate 27. A slide rail 29 is fixedly connected to the second annular plate 28, and a slider 30 is slidably connected inside the slide rail 29. The slider 30 is connected to the circular plate 27 through a connecting rod 31, and the slider 30 is fixedly connected to the limiting protective plate 12 through a push-pull rod 32.

[0030] In the above embodiment, during the rotation of the circular plate 27, the slider 30 moves via the connecting rod 31, the push-pull rod 32 moves during the movement of the slider 30, the limiting protective plate 12 moves during the movement of the push-pull rod 32, and the position of the limiting protective plate 12 is adjusted during the movement of the limiting protective plate 12.

[0031] Specifically, the side wall of the cavity is provided with a guide hole 33 for the limit protection plate 12 to pass through. The guide hole 33 facilitates the limit protection plate 12 to pass through the side wall of the cavity.

[0032] Furthermore, the circular plates 27 are fixedly connected by a rotating rod 45. An operating knob 46 is fixedly connected to the top of the upper rotating rod 45. The operating knob 46 facilitates the rotation of the rotating rod 45, and the circular plates 27 rotate during the rotation of the rotating rod 45.

[0033] In one optional embodiment, a heat-conducting plate 34 is fixedly connected to the inner sidewall of the limiting protective plate 12, and a heat-conducting block 35 is fixedly connected to the heat-conducting plate 34.

[0034] Furthermore, a heat exchange hole 36 is provided on the inner wall of the fruit container 8. An arc-shaped heat-conducting plate 37 is fixedly connected inside the heat exchange hole 36. A first elastic reset member 38 is fixedly connected to the arc-shaped heat-conducting plate 37. A sealing drive plate 39 is fixedly connected to one end of the first elastic reset member 38. A sealing member 40 is fixedly connected to the sealing drive plate 39. The sealing member 40 cooperates with the small end of the heat exchange hole 36.

[0035] In the above embodiment, the heat-conducting block 35 cooperates with the sealing member 40. When the heat-conducting block 35 abuts against the sealing member 40, the sealing member 40 moves. During the movement of the sealing member 40, the cool air of the coolant in the fruit container 8 is transferred from the heat exchange hole 36 to the heat-conducting block 35, and then transferred to the heat-conducting plate 34 through the heat-conducting block 35 to achieve heat dissipation.

[0036] Furthermore, a compensation groove 41 is provided on the side wall of the coolant chamber 9. A second elastic reset member 42 is fixedly connected in the compensation groove 41. A sealing movable plate 43 is fixedly connected to the second elastic reset member 42. The sealing movable plate 43 is movably connected in the compensation groove 41. A volume compensation part 44 is fixedly connected to the sealing movable plate 43.

[0037] In the above structure, when the coolant in the coolant chamber 9 decreases, the second elastic reset member 42 moves. During the movement of the second elastic reset member 42, the sealing movable plate 43 moves. Since the sealing movable plate 43 is sealed and movablely connected to the compensation groove 41, the volume compensation part 44 moves during the movement of the sealing movable plate 43, which facilitates the movement of coolant in the coolant chamber 9.

[0038] In actual use, when lychees need to be stored and transported in the fruit receiving trough 11 of the annular support plate 10, the staff manually rotates the adjusting bolt 16. During the rotation of the adjusting bolt 16, the sliding plate 15 moves, adjusting the position of the first support rod 6 and the second support rod 7. Then, the staff manually pulls the fruit receiving cylinder 8 upward to move it upward. Afterward, the staff manually rotates the adjusting bolt 16 in the opposite direction, moving the sliding plate 15 during the rotation of the adjusting bolt 16. This positions the first support rod 6 and the second support rod 7 below the fruit receiving cylinder 8, thus providing support for the fruit receiving cylinder 8.

[0039] During the above operation, when the fruit container 8 is moved above the horizontal plate 2, the coolant in the coolant chamber 9 flows into the storage box 4, reducing the weight of the fruit container 8 and the supporting effect of the first support rod 6 and the second support rod 7.

[0040] Furthermore, the staff manually pulls the operating knob 46 upward to remove the central support column 47 and the annular support plate 10 from the fruit container 8. Then, the lychees that need to be transported are placed in the fruit container slot 11 of the annular support plate 10. After the fruit container slot 11 of the annular support plate 10 is filled with lychees, the annular support plate 10 and the central support column 47 are placed in the fruit container 8.

[0041] During the loading process, since the operating knob 46 is placed at the top opening of the fruit container 8, a sealing effect is achieved when the operating knob 46 is placed inside the fruit container 8. The operator manually rotates the adjusting bolt 16, and the slide plate 15 moves during the rotation of the adjusting bolt 16. During the movement of the slide plate 15, the positions of the first support rod 6 and the second support rod 7 are adjusted.

[0042] Furthermore, when the first support rod 6 and the second support rod 7 are located within the U-shaped support frame 5, the staff places the fruit container 8 within the receiving space 3. Simultaneously, the staff manually rotates the adjusting bolt 16 in the opposite direction. During the rotation of the adjusting bolt 16, the sliding plate 15 moves, thereby positioning the first support rod 6 and the second support rod 7 above the fruit container 8. The first support rod 6 and the second support rod 7 provide protection, and the fruit container 8 is positioned within the through hole in the middle of the liquid storage box 4, thus limiting the position of the fruit container 8.

[0043] In the above embodiment, when the fruit container 8 is placed in the container space 3, the coolant in the liquid storage box 4 flows into the fruit container 8 through the flexible telescopic tube 22. When the coolant flows into the fruit container 8, the sealing movable plate 43 moves due to the action of the coolant, so that the second elastic reset member 42 is in a compressed state.

[0044] Furthermore, when the coolant in the fruit container 8 is too low due to evaporation or other phenomena, the second elastic reset member 42 resets and moves, thereby moving the sealing movable plate 43 and the volume compensation part 44, thus pushing the coolant in the liquid storage box 4 to a full state.

[0045] When protecting the fruit, the staff manually rotates the operating knob 46. As the operating knob 46 rotates, the circular plate 27 rotates, which in turn moves the slider 30 via the connecting rod 31. As the slider 30 moves, the push-pull rod 32 moves, which in turn moves the limiting protective plate 12. During the movement of the limiting protective plate 12, its position is adjusted so that it is positioned above the lychee, thus protecting the lychee.

[0046] Furthermore, when the limiting protective plate 12 moves above the lychee, the heat-conducting block 35 moves. When the heat-conducting block 35 abuts against the sealing member 40, the sealing member 40 moves. During the movement of the sealing member 40, the cool air in the fruit container 8 is transferred from the heat exchange hole 36 to the heat-conducting block 35, and then transferred to the heat-conducting plate 34 through the heat-conducting block 35, which facilitates the cooling of the coolant.

[0047] Compared to existing methods of transporting fruit by centralized stacking, this application utilizes a first annular plate 10 with a loading trough 11 around the cylindrical block 47. This allows the fruit to be transported to be placed in predetermined positions, and a protective plate 12 extending from the inside of the cylindrical block 47 provides a limit above the loading trough 11. The fruit-supporting structure and the protective structure work together to reduce large relative displacements and direct squeezing of the fruit during transport vibrations.

[0048] The storage cylinder 8 is equipped with a liquid storage space 9 and can be connected to the storage box 4 via a flexible telescopic tube 22, allowing the coolant to flow between the liquid storage space 9 and the storage box 4. When the storage cylinder 8 is loaded, lifted, or placed, the coolant can be transferred by the positional change between the two liquid storage areas, thereby reducing the liquid weight that the storage cylinder 8 needs to bear when it is in the lifted state, and providing cooling medium to the liquid storage space 9 again after the storage cylinder 8 enters the transport position.

[0049] The heat-conducting plate 34 and heat-conducting block 35 on the protective plate 12 can cooperate with the blocking block 40 on the storage cylinder 8. When the protective plate 12 moves to the protective position above the fruit, the heat-conducting block 35 acts synchronously on the blocking block 40, so that the heat exchange structure adjacent to the coolant enters the working state, thereby establishing a heat transfer path between the loading area and the coolant; when the corresponding component is disengaged, the first elastic rubber column 38 can drive the blocking block 40 to reset, so that the protective action and the heat exchange action form a structural linkage.

[0050] The movable plate 43, the second elastic rubber column 42, and the liquid pusher 44 installed on the side wall of the liquid storage space 9 together form a volume compensation structure. When the liquid occupancy state in the liquid storage space 9 changes, the second elastic rubber column 42 can drive the movable plate 43 to move, and change the effective volume of the liquid storage space 9 through the liquid pusher 44, thereby improving the situation where a large empty area appears in the liquid storage space 9 due to liquid transfer, and keeping the coolant and related heat exchange structure in a relatively stable state of cooperation.

[0051] In addition, the first annular plate 10 adopts a detachable connection method, which facilitates the loading, unloading and cleaning of fruits and related components; the first bearing rod 6, the second bearing rod 7 and the shock absorption structure can provide support and buffer during the loading, unloading and transportation of the storage cylinder 8, so that the fruit bearing, protection, cold storage and box support structure form a transportation system that works together.

[0052] In this invention, "fixed connection" means that two interconnected parts are fixed together, generally by means of welding, screws or adhesive; "rotational connection" means that two parts are connected together and can move relative to each other.

[0053] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0054] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
