Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of transport box technology, specifically to a food cold chain transport box. Background Technology
[0002] Cold chain food transportation refers to a transportation method that uses refrigeration or freezing equipment to maintain food at suitable temperatures throughout the transportation process to ensure food quality and safety. This technology is widely used in the logistics of perishable foods such as fresh food, frozen food, dairy products, meat, and seafood.
[0003] Basic transport boxes typically employ a simple box structure, with internal foam padding or ordinary partitions for basic separation. In this case, when different types of fruits and vegetables are stored and transported together in a closed space, the diffusion of ethylene gas and cross-permeation of odors are unavoidable, easily leading to cross-contamination of flavors or premature ripening of the fruits and vegetables. Some transport boxes use a layered drawer structure, which can solve the problems of cross-contamination of flavors and premature ripening. However, each drawer needs to be equipped with an independent lock, and unlocking / locking must be done layer by layer during loading and unloading, which is not only labor-intensive but also time-consuming.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: a food cold chain transport box, comprising a box body and a box lid; the box lid is detachably connected to the opening at the top of the box body by two symmetrically distributed buckles;
[0008] The box is equipped with multiple vertically arranged material loading components. Each material loading component includes a carrier plate. The outer walls of the carrier plate on both sides are provided with vertical sliding grooves. The inner wall of the box is fixedly provided with guide rails that are adapted to the sliding grooves. A material frame with an open top is fixedly installed on the top of the carrier plate. A buffer pad is provided at the open top of the material frame.
[0009] The box cover is provided with a drive mechanism, and the output end of the drive mechanism is connected to a pressure plate. The pressure plate is driven by the drive mechanism to move up and down to press down the buffer pad of the uppermost material loading assembly, thereby pressing all the stacked material loading assemblies tightly.
[0010] Furthermore, the driving mechanism includes a lead screw rotatably mounted on the box cover, the lead screw being threadedly connected to a threaded sleeve, the threaded sleeve being fixed to the center of the top of the pressure plate, and guide rods being fixed at the four corners of the top of the pressure plate, the guide rods being slidably engaged with guide holes opened at the bottom of the box cover.
[0011] Furthermore, the top center of the box cover is provided with an operating groove, and a handle is embedded in the operating groove. The handle is fixedly connected to the top of the lead screw.
[0012] Furthermore, slots are provided at the four corners of the top of the box cover, and the bottom of the box body is fixed with inserts corresponding to the number and position of the slots.
[0013] Furthermore, a sealing ring is fixedly provided at the bottom edge of the lid. When the lid is locked to the box body by the buckle, the sealing ring forms an interference fit with the inner wall at the top opening of the box body.
[0014] Furthermore, the housing includes an inner shell, an insulation layer, and an outer shell arranged sequentially from the inside out, wherein the insulation layer is a closed-cell foam material filled between the inner shell and the outer shell.
[0015] Furthermore, a cold source compartment is formed between the bottommost carrier plate and the bottom surface of the box, and several ice packs are placed inside the cold source compartment.
[0016] Furthermore, the carrier plate surface array has multiple ventilation holes, which penetrate the upper and lower surfaces of the carrier plate.
[0017] Furthermore, there is a predetermined gap between the two side walls adjacent to the material frame and the chute and the inner wall of the box, and handles are symmetrically installed thereon.
[0018] 3. Beneficial effects:
[0019] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: After the driving mechanism drives the pressure plate to descend, the pressure plate will press the buffer pad of the uppermost material loading component, thereby pressing all the stacked material loading components to keep them stable during transportation and play a buffering role.

[0031] See attached document Figure 1-5 A cold chain transport box for food includes a box body 1 and a box lid 2; the box lid 2 is detachably connected to the opening at the top of the box body 1 by two symmetrically distributed buckles 3.
[0032] The box 1 is provided with a plurality of vertically arranged material loading components 4. Each material loading component 4 includes a carrier plate 401. The outer walls of the carrier plate 401 on both sides are provided with vertical sliding grooves 402. The inner wall of the box 1 is fixedly provided with guide rails 5 adapted to the sliding grooves 402. A material frame 403 with an open top is fixedly installed on the top of the carrier plate 401. A buffer pad 404 is provided at the open top of the material frame 403.
[0033] The box cover 2 is provided with a drive mechanism 6. The output end of the drive mechanism 6 is connected to a pressure plate 7. The pressure plate 7 is driven by the drive mechanism 6 to move up and down to press down the buffer pad 404 of the uppermost material loading assembly 4, thereby pressing all the stacked material loading assemblies 4 tightly.
[0034] In this embodiment, after different kinds of fruits and vegetables are placed into the material boxes 403 of each layer, each set of material-carrying components 4 can be placed into the box body 1 in sequence by sliding the vertically extending slide 402 and the guide rail 5. Then, the box cover 2 is installed at the opening at the top of the box body 1 by the buckle 3. Then, the pressure plate 7 is driven down by the drive mechanism 6 so that the pressure plate 7 presses the buffer pad 404 of the uppermost material-carrying component 4, thereby pressing all the stacked material-carrying components 4 tightly, so that they remain stable during transportation and play a buffering role. At this time, the material box 403 is in a sealed state, which can prevent the cross-contamination of flavors and ripening of fruits and vegetables.
[0035] The driving mechanism 6 includes a lead screw 601 rotatably mounted on the cover 2. The lead screw 601 is threadedly connected to a threaded sleeve 602, which is fixed to the top center of the pressure plate 7. Guide rods 603 are fixed at the four corners of the top of the pressure plate 7. The guide rods 603 slide in conjunction with the guide holes 604 opened at the bottom of the cover 2. An operating groove 201 is provided at the top center of the cover 2. A handle 605 is embedded in the operating groove 201 and is fixedly connected to the top of the lead screw 601.
[0036] In this embodiment, after the handle 605 is rotated, the lead screw 601 rotates synchronously. With the threaded connection between the lead screw 601 and the threaded sleeve 602, the guide rod 603 can be driven to slide in the guide hole 604, thereby realizing the lifting and lowering of the pressure plate 7.
[0037] The top four corners of the box cover 2 are provided with slots 202, and the bottom of the box body 1 is fixed with inserts 104 corresponding to the number and position of the slots 202.
[0038] In this embodiment, when the device is stacked, the upper insert 104 can be inserted into the lower slot 202 to improve the stability of the stack. The handle 605 is located in the operating slot 201 and will not protrude from the top of the cover 2, thus not affecting the stacking of the device.
[0039] A sealing ring 203 is fixedly provided on the bottom edge of the box cover 2. When the box cover 2 is locked to the box body 1 by the buckle 3, the sealing ring 203 forms an interference fit sealing contact with the inner wall at the top opening of the box body 1.
[0040] In this embodiment, the sealing ring 203 is used to achieve a sealed connection between the box body 1 and the box cover 2, which is used to improve the heat preservation effect.
[0041] The housing 1 includes an inner shell 101, an insulation layer 102, and an outer shell 103 arranged sequentially from the inside to the outside. The insulation layer 102 is a closed-cell foam material filled between the inner shell 101 and the outer shell 103.
[0042] In this embodiment, the structure of the inner shell 101, the insulation layer 102, and the outer shell 103 of the box 1 not only further improves the insulation effect, but also plays a role in buffer protection.
[0043] A cold source compartment 105 is formed between the bottom carrier plate 401 and the bottom surface of the box 1, and several ice packs 8 are placed in the cold source compartment 105; a plurality of ventilation holes 405 are arrayed on the surface of the carrier plate 401, and the ventilation holes 405 penetrate the upper and lower surfaces of the carrier plate 401.
[0044] In this embodiment, a limiting part is set at the bottom of the guide rail 5, so that a cold source compartment 105 is formed between the bottommost carrier plate 401 and the bottom surface of the box 1. The ice pack 8 placed in it can reduce the temperature inside the box 1 and achieve the effect of preservation. The temperature inside the box 1 can be more uniform through the vent 405.
[0045] There is a predetermined gap between the two side walls adjacent to the material frame 403 and the chute 402 and the inner wall of the box 1, and handles 406 are symmetrically assembled thereon.
[0046] In this embodiment, the handle 406, in conjunction with the aforementioned gap, facilitates the placement of the material-carrying component 4 into or from the box 1 by the staff.
[0047] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
[0048] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art.
