[0002] The controlled atmosphere box for fruit and vegetable storage is a commonly used device for fruit and vegetable preservation. By precisely regulating the temperature, humidity, and gas environment, the storage period can be effectively extended and the quality can be maintained. In the existing controlled atmosphere box, the internal storage space is mostly a single chamber or divided into multiple chambers by partitions. When storing fruits and vegetables, they are often placed inside in a scattered manner or after being simply packaged. A large number of fruit and vegetable items are stacked and stored inside. When taking them out later, it is rather troublesome. It is difficult to accurately find the required items, and it requires multiple long-time turnovers to search. The search efficiency is low, and the box body is opened for a long time, resulting in the internal storage environment being in contact with the external environment for a long time, affecting the preservation effect of fruits and vegetables.

One end of the load-carrying plate is connected to the outer wall of the main shaft. A covering component for covering the items placed on the corresponding load-carrying plate below is connected to the bottom of each load-carrying plate. The covering component is arranged to be foldable. A plurality of positioning plates are connected to both sides of the inner wall of the storage cavity from top to bottom. Two positioning plates at the same height on both sides form a group, and the two positioning plates in the same group can be used to position the storage layer at the same height.

[0005] Optionally, the main shaft includes load-bearing shaft rods at the upper and lower ends and connecting shafts connected end to end between the two load-bearing shaft rods. The bottom of the upper load-bearing shaft rod and the top of the lower load-bearing shaft rod are rotatably installed at the end of the connecting shaft connected to them through second bearings, and the ends between adjacent connecting shafts are also rotatably installed through second bearings. A storage layer is correspondingly installed on the outer walls of the load-bearing shaft rods at the upper and lower ends and the outer wall of each connecting shaft.

[0006] Optionally, pin holes are provided on the upper side above the upper bearing shaft rod, the lower side below the lower bearing shaft rod, and the sides connecting the upper and lower ends of the connecting shaft. At the connection between the upper and lower bearing shaft rods and the connecting shaft, and at the connection between the ends of adjacent two connecting shafts, clamping plates are installed by clamping. At the upper and lower ends on one side of each clamping plate, pin rods are connected. The two pin rods are respectively inserted into the pin holes at the upper and lower ends of the connection.

[0007] Optionally, jacks are provided on the side wall of the carrier plate away from the main shaft. Inside one end of the positioning plate facing the carrier plate, an installation groove is provided. Inside the installation groove, a plugging plate is slidably installed. Along the length direction on one side of the positioning plate, a moving groove is provided. The moving groove penetrates through the side wall of the positioning plate and communicates with the installation groove. One side of the plugging plate is connected with a handle. One end of the handle penetrates through the moving groove and extends to the outside. After the plugging plate moves outwards from the inside of the installation groove, it can be plugged into the jacks at corresponding positions.

[0008] Optionally, a storage cavity is provided at the bottom end of the carrier plate. The covering assembly includes a sealing frame and a covering bag. The sealing frame is installed at the bottom end of the carrier plate. A through hole is provided through the inside of the sealing frame. Between the bottom end of the carrier plate and the top end of the sealing frame, a covering bag is installed. The outer walls at the upper and lower ends of the covering bag are respectively connected with the inner wall below of the storage cavity and the inner wall above of the through hole.

[0009] Optionally, sealing magnetic strips are embedded and installed at the upper and lower edges of the sealing frame and at the upper and lower edges of the carrier plate. The sealing frame is magnetically adsorbed and connected to the carrier plate through the sealing magnetic strips.

[0010] Optionally, a limiting groove is provided on the inner side wall of the through hole. At both ends on the side close to the main shaft inside the through hole, anti - detachment strips made of rubber are connected. One end of the anti - detachment strip away from the main shaft is connected with a limiting ball. The limiting ball is slidably installed in the limiting groove on the side away from the main shaft inside the through hole.

[0011] Optionally, at the upper and lower ends of the main shaft, fixing plates are rotatably installed through first bearings. The upper and lower fixing plates inside the storage cavity are both connected to the end of the storage cavity through a plurality of bolts.

[0012] A method for transporting and storing fruits and vegetables, which is used for the above - mentioned storage box, and this storage method further includes the following steps: Step 1: Install multiple clamping plates at multiple rotating connection points on the main shaft. The main shaft is an integral whole. All the plugging plates are disengaged from the jacks. Place storage items on the carrier plate, and then close the door panel. The storage cavity is closed, and the items stored inside the storage cavity can be stored. Step 2: If the items inside the storage cavity need to be taken out or some items need to be found, rotate one of the storage layers, driving the main shaft to rotate. The items on each storage layer rotate accordingly. The staff can find the required items and then quickly take them out. Step 3: If the stored items include items that affect other items, place them separately on the same storage layer and wrap them with a wrapping bag to reduce their impact on other items. When using the wrapping bag for wrapping, pull down the corresponding plugging frame and move the anti-detachment strips inside the through holes to both sides, keeping the through holes open. The plugging frame moves downward and is magnetically adsorbed to the sealing magnetic strip above the load-bearing plate at the corresponding position below. The items on the load-bearing plate pass through the through holes, and the wrapping bag is pulled down and unfolded to wrap the items on the load-bearing plate. Step 4: When large-sized items need to be stored inside the storage cavity, disassemble the main shaft together with the storage layer and place the items to be stored in the storage cavity for storage.

[0013] Advantages of the present invention: Larger-sized items and smaller-sized items can be stored in this storage box. Moreover, the storage device can also be adjusted according to the properties of different items to avoid interference and influence among multiple stored items.

[0014] Furthermore, the storage layer is rotatably arranged. When the items inside the storage cavity need to be taken out or some items need to be found, one of the storage layers can be rotated, thereby causing the main shaft to rotate and driving all the storage layers to rotate simultaneously. The items on each storage layer can be fully seen by the staff as they rotate, so that the required items can be quickly found and taken out. This enables the stacked and stored items to be quickly searched and taken out, improving work efficiency. At the same time, during the storage and transportation of items, when the staff checks the items, checking in a rotating manner is more thorough, avoiding the situation where only some scattered items on the outside are seen and the storage situation of the internal items cannot be known in time, and fully checking the storage situation of the items, which is convenient for timely adjusting the storage environment of the items to ensure the freshness and integrity of the items.

Detailed implementation manners

[0027] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0028] Please refer to Figures 1-10 As shown, a fruit and vegetable transportation and storage box body includes a box body 1 and a door panel 2 rotatably installed on its side. A storage cavity 4 is arranged inside the box body 1, and a storage component is rotatably installed inside the storage cavity 4. The storage component includes a main shaft vertically rotatably installed inside the storage cavity 4, and a plurality of storage layers are arranged on the outer part of the main shaft from top to bottom. Each storage layer includes a plurality of load-carrying boards 6. One end of the load-carrying board 6 is connected to the outer wall of the main shaft. A covering component for covering the items placed on the corresponding load-carrying board 6 below is connected to the bottom of each load-carrying board 6. The covering component is arranged to be foldable. A plurality of positioning plates 8 are connected to both sides of the inner wall of the storage cavity 4 from top to bottom. Two positioning plates 8 at the same height on both sides are in a group, and the two positioning plates 8 in the same group can be used to position the storage layer at the same height.

[0029] As a technical optimization solution of the present invention, the main shaft includes load-bearing shaft rods 3 at both the upper and lower ends and a connecting shaft 5 connected end to end between the two load-bearing shaft rods 3. The bottom of the upper load-bearing shaft rod 3 and the top of the lower load-bearing shaft rod 3 are rotatably installed at the ends of the connecting shaft 5 connected thereto through second bearings, and the ends of adjacent two connecting shafts 5 are also rotatably installed through second bearings. A storage layer is correspondingly installed on the outer walls of the load-bearing shaft rods 3 at both the upper and lower ends and the outer wall of each connecting shaft 5. So that the multiple connecting shafts 5 on the main shaft and the load-bearing shaft rods 3 at both ends can rotate independently, and then the storage layers outside them can rotate independently to meet different usage requirements.

[0030] As a technical optimization solution of the present invention, pin holes 10 are provided on one side above the upper load-bearing shaft rod 3, one side below the lower load-bearing shaft rod 3, and one side of the upper and lower ends of the connecting shaft 5. Clamping plates 9 are clamped and installed on the outer walls at the connection positions of the upper and lower load-bearing shaft rods 3 and the connecting shaft 5 and at the connection positions of the ends of adjacent two connecting shafts 5. At the upper and lower ends on one side of the clamping plate 9, there are connecting pin rods 24, and the two pin rods 24 are respectively inserted into the pin holes 10 at the upper and lower ends of the connection position. Through the insertion and installation of the pin rods 24 and the pin holes 10, the clamping plate 9 is convenient for installation and disassembly during use. It can not only make the main shaft be used as a whole, but also make each part rotate independently for use.

[0031] As a technical optimization solution of the present invention, insertion holes 12 are provided on the side wall of the carrier plate 6 away from the main shaft. An installation groove 16 is provided inside one end of the positioning plate 8 facing the carrier plate 6. A plug-in plate 17 is slidably installed inside the installation groove 16. A moving groove 15 is provided along the length direction on one side of the positioning plate 8, and the moving groove 15 penetrates through the side wall of the positioning plate 8 and communicates with the installation groove 16. One side of the plug-in plate 17 is connected with a handle 18, and one end of the handle 18 penetrates through the moving groove 15 and extends to the outside. After the plug-in plate 17 moves outwards from the inside of the installation groove 16, it can be inserted into the insertion hole 12 at the corresponding position. By pushing the handle 18 to move inside the moving groove 15, the plug-in plate 17 can be driven to move inside the installation groove 16. When the plug-in plate 17 is inserted into the corresponding insertion hole 12, the storage layer of this layer can be limited from rotating, so that it cannot rotate and maintains a stable position.

[0032] As a technical optimization solution of the present invention, a storage cavity 19 is provided at the bottom end of the load-bearing plate 6. The covering component includes a blocking frame 7 and a covering bag 11. The blocking frame 7 is installed at the bottom end of the load-bearing plate 6. A through hole 25 is penetrated through the inside of the blocking frame 7. A covering bag 11 is installed between the bottom end of the load-bearing plate 6 and the top end of the blocking frame 7. The outer walls of the upper and lower ends of the covering bag 11 are respectively connected to the lower inner wall of the storage cavity 19 and the upper inner wall of the through hole 25. Sealing magnetic strips 20 are embedded and installed at the edges of the upper and lower ends of the blocking frame 7 and the edges of the upper and lower ends of the load-bearing plate 6. The blocking frame 7 is magnetically adsorbed and connected to the load-bearing plate 6 through the sealing magnetic strips 20. A limiting groove 22 is opened on the inner side wall of the through hole 25. Both ends of the side close to the main shaft inside the through hole 25 are connected with anti-detachment strips 21 made of rubber. One end of the anti-detachment strip 21 away from the main shaft is connected with a limiting ball 23. The limiting ball 23 is slidably installed in the limiting groove 22 on the side away from the main shaft inside the through hole 25.

[0033] The blocking frame 7 is magnetically adsorbed by using the sealing magnetic strip 20, which is convenient for disassembly and installation during use, and thus convenient for the unfolding and storage of the covering bag 11. Pulling downwards can make the covering bag 11 unfold, and pushing the blocking frame 7 upwards can store and place the covering bag 11.

[0034] As a technical optimization solution of the present invention, fixing plates 14 are rotatably installed at the upper and lower ends of the main shaft through first bearings 13. The upper and lower two fixing plates 14 are both connected to the ends of the storage cavity 4 through a plurality of bolts inside the storage cavity 4. The setting of the fixing plates 14 is convenient for the installation and disassembly of the main shaft and the storage cavity 4, and thus the inside of the storage cavity 4 can adapt to the placement and storage of items of different sizes.

[0035] A method for transporting and storing fruits and vegetables, which is used for the above storage box body, and the storage method further includes the following steps: Step 1: Install a plurality of clamping plates 9 at multiple rotating connection points on the main shaft. The main shaft is an integral body, and all the plugging plates 17 are disengaged from the jacks 12. Place storage items on the load-bearing plate 6, and then close the door panel 2. The storage cavity 4 is closed, and the items stored inside the storage cavity 4 can be stored; Step 2: If the items inside the storage cavity 4 need to be taken out or some items need to be searched, rotate one of the storage layers to drive the main shaft to rotate. The items on each storage layer rotate accordingly. The staff can find the required items and then take them out quickly; Step 3: If the stored items include items that affect other items, place them separately on the same storage layer and wrap them with the wrapping bag 11 to reduce their impact on other items. When using the wrapping bag 11 for wrapping, pull down the corresponding blocking frame 7 and move the anti-detachment strips 21 inside the through holes 25 to both sides, so that the through holes 25 remain open. The blocking frame 7 moves downward and is magnetically adsorbed to the sealing magnetic strip 20 above the carrier plate 6 at the corresponding position below. The items on the carrier plate 6 pass through the through holes 25, and the wrapping bag 11 is pulled down and unfolded to wrap the items on the carrier plate 6. Step 4: When large-sized items need to be stored inside the storage cavity 4, remove the main shaft together with the storage layer, and place the items to be stored in the storage cavity 4 for storage.

[0036] When the present invention is in use, install the plurality of clamping plates 9 at the plurality of rotating connection points on the main shaft, so that the main shaft forms a whole, and all the storage layers on the main shaft can rotate simultaneously. Then push the handle 18, so that all the plug-in plates 17 are disengaged from the jacks 12, and the plug-in plates 17 enter the installation grooves 16 for storage, without affecting the normal rotation of the subsequent carrier plates 6. According to the actual item placement requirements, storage can be carried out on many carrier plates 6. The same kind of items or different kinds of items can be placed on the same storage layer. If the placed items are large in size, they can be jointly placed on two adjacent carrier plates 6 on the same storage layer. Then close the door panel 2 to seal the storage cavity 4. Since the box body 1 itself has the function of controlled atmosphere cold storage, the items stored inside the storage cavity 4 can be stored fresh.

[0037] When the items inside the storage cavity 4 need to be taken out or some items need to be searched, one of the storage layers can be rotated, so that the main shaft rotates, and at the same time, all the storage layers can be driven to rotate. The items on each storage layer can be fully seen by the staff as they rotate, so that the required items can be quickly found and taken out. This enables the stacked items to be quickly searched and taken out, improving work efficiency. At the same time, during the storage and transportation of items, when the staff checks the items, checking in a rotating manner is more thorough, avoiding the situation where only some scattered items on the surface are seen and the storage situation of the internal items cannot be known in time, and fully checking the storage situation of the items is convenient for timely adjusting the storage environment of the items to ensure the freshness and integrity of the items. If it is necessary to keep the internal storage layer stable during transportation, it can be fixed through the positioning plates 8 on both sides. Push the handle 18 to drive the plug-in plate 17 to insert into the inside of the jack 12, so that the storage layer is kept stable and the main shaft cannot rotate.

[0038] If among the many stored items there are items with strong odors or items that affect other items, they can be placed separately on the same storage layer and wrapped with the wrapping bag 11 to reduce their impact on other items. When using the wrapping bag 11 for wrapping, pull down the corresponding blocking frame 7, and move the anti-detachment strips 21 inside the through hole 25 to both sides, so that the through hole 25 can remain open. The blocking frame 7 moves downward and is magnetically adsorbed to the sealing magnetic strip 20 above the carrier plate 6 at the corresponding position below. The items on the carrier plate 6 pass through the through hole 25, and the wrapping bag 11 is pulled down and unfolded to wrap the items on the carrier plate 6. If the item with a strong odor or an item that affects other items is relatively large in size and difficult to be wrapped with the wrapping bag 11, other affected items can also be wrapped with the wrapping bag 11 to achieve the corresponding protective effect. This enables various types of items to be stored inside the storage cavity 4, and good protection can be obtained during the storage process.

[0039] When the wrapping bag 11 needs to be stored after use, pull up the corresponding blocking frame 7, and move the anti-detachment strips 21 on both sides to the middle position of the through hole 25. After the blocking frame 7 moves upward, it is magnetically adsorbed to the sealing magnetic strip 20 at the bottom of the corresponding upper carrier plate 6. The wrapping bag 11 is pressed into the storage cavity 19 at the bottom of the carrier plate 6 and is restricted by the two anti-detachment strips 21, so that the wrapping bag 11 is not easily detached from the storage cavity 19 and can be stably stored.

[0040] If the storage layers on the main shaft need to rotate independently of each other, all the clamping plates 9 on the main shaft can be pulled outwards, and the pin rods 24 are pulled out of the pin holes 10, so that the storage layers can rotate independently. And for the storage layers that do not need to rotate, they can be fixed by the positioning plates 8 on both sides. Push the handle 18 to drive the insertion plate 17 to insert into the inside of the jack 12, so that the storage layer of this layer cannot rotate and can maintain a stable placement, meeting various usage requirements. And during use, some storage layers can also be kept rotating or stable, and some adjacent two storage layers can be kept stable or rotating simultaneously. According to actual needs, remove the clamping plates 9 at the corresponding positions to achieve this.

[0041] If relatively large-sized items need to be stored inside the storage cavity 4, the main shaft together with the storage layers can be disassembled. Loosen the bolts on the fixing plate 14, and the fixing plate 14 together with parts such as the main shaft can be removed. The item to be stored can be directly placed in the storage cavity 4 for storage. Or according to the size of the item, storage partitions can be placed on the two positioning plates 8 in the same group, and then the storage cavity 4 can be divided into multiple storage spaces by multiple partitions, and corresponding items can be placed on each partition.
