Description

Technical Field

[0001] This invention relates to the field of fresh-keeping transportation equipment technology, and in particular to a kiwifruit fresh-keeping transportation equipment and its preservation method. Background Technology

[0002] In the cold chain logistics transportation of kiwifruit, the most commonly used preservation transportation equipment is the insulated box. The insulated box can provide a stable temperature and humidity environment, reduce the loss of moisture and microbial contamination of kiwifruit during transportation, thereby extending its shelf life.

[0003] The inventors discovered that during the preservation and transportation of kiwifruit using insulated boxes, if there are many kiwifruit, the kiwifruit at the top of the box will compress the kiwifruit at the bottom due to gravity. This may cause the kiwifruit at the bottom to be damaged during long-term transportation. When there are few kiwifruit, they cannot fill the insulated box completely, and there are large gaps between the kiwifruit. This makes the kiwifruit susceptible to vibration and other factors during transportation, causing them to collide with the inner wall of the box, which may also damage the kiwifruit and thus hinder its preservation. Summary of the Invention

[0004] This invention addresses the problem that kiwifruit may be damaged due to compression or collision with the inner wall of the preservation box when stored in a large or small quantity. It proposes a kiwifruit preservation and transportation device and its preservation method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a kiwifruit preservation and transportation device, comprising a preservation box body, a sealing cover rotatably connected to one side of the top of the preservation box body, a sealing ring fixedly connected to one edge of the sealing cover, the preservation box body and the sealing cover being made of PU material, and an auxiliary device that can be adjusted according to the specific quantity of kiwifruit and protects the kiwifruit is provided inside the preservation box body.

[0006] The effect achieved by the above-mentioned components is as follows: by setting up the auxiliary device, the auxiliary device can be adjusted differently when there are many kiwis and few kiwis. This helps to prevent the kiwis at the bottom from being squeezed and damaged when there are too many kiwis, and also prevents the kiwis from colliding with the inner wall of the preservation box and causing damage when there are few kiwis. This makes the preservation and transportation device easier to preserve kiwis.

[0007] Preferably, the auxiliary device includes a rotating shaft, on the outer surface of which a first partition and a second partition are alternately arranged, and the outer surface of the rotating shaft is rotatably connected to the inner walls of both the first and second partitions. The first and second partitions are both located inside the body of the preservation box. Slider blocks are fixedly connected to both ends of the rotating shaft. Slide rails are symmetrically arranged on both sides of the inner wall of the preservation box. The outer surface of the slider is slidably fitted to the inner wall of the slide rail. A gear is provided on the side of each slider that is close to it. A toothed plate is fixedly connected to one side of the inner wall of the slide rail. The outer surface of the gear meshes with the inner wall of the toothed plate. A first pulley is fixedly connected to one side of the gear. The first pulley and the gear are integrally formed. The outer surface of the shaft is rotatably connected to the gear and the inner wall of the first pulley. A transmission belt is provided on the outer surface of the first pulley, and a second pulley is provided on the inner wall of the transmission belt. The two second pulleys are respectively located on the side of the first partition and the second partition that are far apart. A threaded rod is fixedly connected to one end of each pulley. The outer surfaces of the two threaded rods are rotatably connected to the inner walls of the first partition and the second partition, respectively. An air chamber is provided at the bottom of both the first partition and the second partition. A push block is slidably connected to the inner wall of the air chamber. The outer surface of the threaded rod is threadedly connected to the inner wall of the push block. An air bladder is provided on the side of the top of both the first partition and the second partition that are far apart. One end of the air bladder is connected to the inner wall of one end of the air chamber.

[0008] The aforementioned components achieve the following effects: By setting a first partition and a second partition, both of which can rotate on the outer surface of the rotating shaft, when there are many kiwis, rotating the first or second partition and placing kiwis at the bottom of the first or second partition, while also placing kiwis above the first and second partitions, can divide a large number of kiwis into upper and lower parts. The slider can slide on the inner wall of the slide rail, facilitating the adjustment of the position of the first and second partitions according to the actual size of the bottom kiwis. This allows the first and second partitions to bear the weight of the top kiwis without squeezing the bottom kiwis, thus reducing the pressure on the bottom kiwis and minimizing damage when there are many kiwis. When there are few kiwis, placing them directly on top of the first and second partitions and pushing them downwards... The first and second partitions move the kiwifruit towards the bottom of the inner wall of the refrigerator body. Simultaneously, they move the slider downwards along the inner wall of the slide rail. A rotating shaft drives two gears downwards, which rotate continuously under the action of a toothed plate. A first pulley connected to the gears drives a transmission belt, which in turn drives a second pulley. The second pulley drives a threaded rod, which in turn drives a pusher block to slide along the inner wall of the air chamber. The air chamber is made of rigid material. When the pusher block pushes, it pushes air from the air chamber into the air bladder, causing the air bladder to inflate. The further the first and second partitions move downwards, the larger the air bladder inflates. The inflated air bladder reduces the kiwifruit's movement range and protects it from damage when it impacts the air bladder, preventing damage when the kiwifruit is small.

[0009] Preferably, the top of the first partition and the second partition are evenly provided with a plurality of through slots.

[0010] The effect achieved by the above-mentioned components is that by setting the through groove, the space between the first partition and the second partition can be connected, preventing the air inside the refrigerator body from not circulating, reducing the growth of bacteria, and reducing the weight of the first partition and the second partition, thereby reducing the fixing pressure on the first partition and the second partition.

[0011] Preferably, the inner wall of the slider is threaded with a threaded pin, one end of which is fixedly connected to an operating block, and the outer surface of the operating block is provided with a protrusion.

[0012] The effects achieved by the above components are as follows: By setting the threaded pin, under the action of the operating block, rotating the operating block will drive the threaded pin to rotate. The threaded pin will extend and retract on the inner wall of the slider until one end of the threaded pin abuts against one side of the inner wall of the slide rail. Then, the threaded pin can fix the slider and the slide rail under the action of friction, thereby fixing the first partition and the second partition. This helps to prevent the first partition and the second partition from moving downward under their own weight and pressing down on the kiwi fruit at the bottom. The outer surface of the operating block is provided with protrusions, which can increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the threaded pin.

[0013] Preferably, a hidden groove is provided on one side of the operating block, and the threaded pin is disposed inside the hidden groove.

[0014] The effect achieved by the above-mentioned components is as follows: by setting a hidden groove, when one end of the threaded pin abuts against the inner wall of the slide rail, the operating block just fully enters the inner wall of the hidden groove. At this time, the operating block will not protrude from one side of the slider, thus not obstructing the storage of kiwifruit. In addition, the operating block is also provided with a regular hexagonal groove, which makes it easy to adjust the operating block with a hexagonal wrench after the operating block enters the inner wall of the hidden groove.

[0015] Preferably, a rubber strip is adhered to one side of the inner wall of the slide rail, and the rubber strip is disposed at one end of the threaded pin.

[0016] The effect achieved by the above components is as follows: by setting the rubber strip, one side of the slide rail can be used to abut against one end of the threaded pin, which helps to prevent the threaded pin from damaging the inner wall of the food storage box. At the same time, the rubber strip can increase the friction between the threaded pin and the inner wall of the slide rail, thereby making it less likely for the threaded pin to loosen its fixation on the first and second partitions.

[0017] Preferably, a limiting plate is fixedly connected to the top of both the first partition and the second partition on opposite sides. One side of the limiting plate abuts against one side of the inner wall of the food storage box, and the outer surface of the airbag is fixedly connected to the other side of the limiting plate.

[0018] The effect achieved by the above-mentioned components is as follows: by setting the limiting plates, which are respectively set on both sides of the first partition and the second partition, the first partition and the second partition can be limited to the inner wall of the refrigerator body, so that the first partition and the second partition can be kept horizontal under normal conditions, which is convenient for placing kiwifruit.

[0019] Preferably, the top of the limiting plate is symmetrically fixedly connected with a locking block, and the inner wall of the two locking blocks is fitted with the same rectangular plate.

[0020] The effect achieved by the above components is as follows: by setting a rectangular plate and inserting the rectangular plate into the inner wall of the two locking blocks, the locking blocks can limit the rectangular plate, and the rectangular plate can limit the space between the two limiting plates. This helps to prevent the first and second partitions from bending inward under the influence of vibration during transportation, which would cause damage to the kiwifruit.

[0021] Preferably, an extension plate is fixedly connected to the bottom of the rectangular rod, the bottom of the extension plate abuts against the top of the first partition and the second partition, and a sponge plate is fixedly connected to the side of the two extension plates that are close to each other.

[0022] The effect achieved by the above components is as follows: by setting the limiting plates, the two sides between the two limiting plates can be limited, which can prevent the kiwi fruit from hitting the gears and other components. At the same time, the sponge plate on one side of the limiting plate can further buffer and protect the side where the two limiting plates are close together, which helps to prevent the kiwi fruit that hits the limiting plate from being damaged.

[0023] Preferably, first, place an appropriate amount of ice packs inside the refrigerator body. The refrigerator body is made entirely of PU, or polyurethane, which has strong heat insulation properties. After placing the ice and kiwis inside the refrigerator body, tighten the sealing lid. The sealing lid, under the action of the sealing ring, will seal the refrigerator body. When there are many kiwis, rotate the first or second partition and place kiwis and ice packs at the bottom of the first or second partition. At the same time, kiwis and ice packs can also be placed above the first and second partitions. This can divide a large number of kiwis into upper and lower parts, and the slider can slide on the inner wall of the slide rail, which makes it easier to select the bottom part. The actual size of the kiwifruit is used to adjust the positions of the first and second partitions, ensuring they support the weight of the top kiwifruit without compressing the bottom ones. Rotating the operating block then drives the threaded pin to rotate. The threaded pin extends and retracts within the slider until one end abuts against the rubber strip on one side of the slide rail, and the operating block is fully inserted into the hidden groove. At this point, the threaded pin, under friction, secures the slider and slide rail, thus fixing the first and second partitions in place. This prevents the first and second partitions from shifting downwards under their own weight and pressing down on the bottom kiwifruit. Finally, the rectangular plate is inserted into the two locking blocks. The inner wall features a locking mechanism that limits the rectangular plate, which in turn limits the space between the two limiting plates. Together, these plates secure the first and second partitions, reducing pressure on the bottom kiwis and minimizing damage when there are many kiwis. When there are fewer kiwis, placing them and an ice pack directly on top of the first and second partitions and pushing them downwards moves the kiwis towards the bottom of the inner wall of the refrigerator. Simultaneously, this moves the slider downwards along the inner wall of the slide rail, and the rotating shaft drives two gears downwards. As the gear moves downwards, it rotates continuously under the action of the gear plate. The first pulley connected to the gear drives the transmission belt to move, which in turn drives the second pulley to rotate. The second pulley drives the threaded rod to rotate, and the threaded rod drives the pusher block to slide against the inner wall of the air chamber. The air chamber is made of rigid material. When the pusher block pushes, it pushes the air in the air chamber into the air bladder, causing the air bladder to inflate. The more the first and second partitions move downwards, the larger the air bladder inflates. The inflated air bladder reduces the range of movement of the kiwi fruit and protects the kiwi fruit when it hits the air bladder, thus preventing damage when there are few kiwi fruits.

[0024] In summary, the beneficial effects of this invention are as follows: By incorporating auxiliary devices, the system can be adjusted to accommodate different quantities of kiwifruit, including a large quantity and a small quantity. These devices separate and protect the kiwifruit through a first partition, a second partition, and an airbag. This helps prevent damage to the bottom kiwifruit from being squeezed when there are too many kiwifruit, and also prevents damage from collisions between the kiwifruit and the inner wall of the preservation box when there are fewer kiwifruit. This makes the preservation and transportation device easier to use for storing kiwifruit. Attached Figure Description

[0026] Reference Figures 1-9As shown, this embodiment discloses a food storage box body 1, characterized in that: a sealing cover 2 is rotatably connected to one side of the top of the food storage box body 1, and a sealing ring 3 is fixedly connected to the edge of one side of the sealing cover 2. Both the food storage box body 1 and the sealing cover 2 are made of PU material. An auxiliary device 4 is provided inside the food storage box body 1, which can be adjusted according to the specific quantity of kiwifruit and protect the kiwifruit. The auxiliary device 4 includes a rotating shaft 41, and a first partition 42 and a second partition 43 are alternately arranged on the outer surface of the rotating shaft 41. The outer surface of the rotating shaft 41 is rotatably connected to the inner walls of the first partition 42 and the second partition 43. The first partition 42 and the second partition 43 are both located inside the food storage box body 1, and both ends of the rotating shaft 41 are fixedly connected to... The container has sliders 45 and slide rails 46 symmetrically arranged on both sides of the inner wall of the main body 1. The outer surface of the sliders 45 is slidably fitted to the inner wall of the slide rails 46. Gears 47 are provided on the side of the two sliders 45 that are close to each other. A toothed plate 48 is fixedly connected to one side of the inner wall of the slide rails 46. The outer surface of the gears 47 meshes with the inner wall of the toothed plate 48. A first pulley 49 is fixedly connected to one side of the gears 47. The first pulley 49 and the gears 47 are integrally formed. The outer surface of the rotating shaft 41 is rotatably connected to the inner wall of both the gears 47 and the first pulley 49. A drive belt 410 is provided on the outer surface of the first pulley 49. A second pulley 411 is provided on the inner wall of the drive belt 410. The two second pulleys 411 are respectively located on... On the side of the first partition 42 and the second partition 43 that are far apart, one end of the pulley is fixedly connected to a threaded rod 412. The outer surfaces of the two threaded rods 412 are rotatably connected to the inner walls of the first partition 42 and the second partition 43, respectively. An air chamber 413 is provided at the bottom of both the first partition 42 and the second partition 43. A push block 414 is slidably connected to the inner wall of the air chamber 413. The outer surface of the threaded rod 412 is threadedly connected to the inner wall of the push block 414. An air bladder 415 is provided on the side of the top of both the first partition 42 and the second partition 43 that are far apart. One end of the air bladder 415 is connected to the inner wall of one end of the air chamber 413. By setting the first partition 42 and the second partition 43, both the first partition 42 and the second partition 43 can be rotated outside the shaft 41. The surface is rotated. When there are many kiwis, the first partition 42 or the second partition 43 is rotated, and kiwis are placed at the bottom of the first partition 42 and the second partition 43. At the same time, kiwis can also be placed above the first partition 42 and the second partition 43. This can divide a large number of kiwis into upper and lower parts. The slider 45 can slide on the inner wall of the slide rail 46, which makes it easy to adjust the position of the first partition 42 and the second partition 43 according to the actual size of the bottom kiwis. This allows the first partition 42 and the second partition 43 to bear the weight of the top kiwis without squeezing the bottom kiwis. This can reduce the pressure on the bottom kiwis and reduce damage to the kiwis when there are many kiwis.When there are few kiwis, place them directly on top of the first partition 42 and the second partition 43, and push the first partition 42 and the second partition 43 downwards. The first partition 42 and the second partition 43 will move the kiwis towards the bottom of the inner wall of the refrigerator body 1. At the same time, they will move the slider 45 downwards along the inner wall of the slide rail 46. Simultaneously, the rotating shaft 41 will drive the two gears 47 downwards. As the gears 47 move downwards, they will rotate continuously under the action of the toothed plate 48. The first pulley 49 connected to the gear 47 will drive the transmission belt 410 to move, and the transmission belt 410 will then drive the second... When the pulley 411 rotates, the second pulley 411 drives the threaded rod 412 to rotate. The threaded rod 412 drives the pusher block 414 to slide against the inner wall of the air chamber 413. The air chamber 413 is made of rigid material. When the pusher block 414 pushes, it pushes the air in the air chamber 413 into the air bladder 415, causing the air bladder 415 to inflate. The more the first partition 42 and the second partition 43 move downwards, the larger the air bladder 415 inflates. The inflated air bladder 415 reduces the movement range of the kiwi fruit and protects it when it hits the air bladder 415, thus preventing damage when the kiwi fruit is small.

[0027] Reference Figures 2-5 As shown, this embodiment discloses that the top of the first partition 42 and the second partition 43 are evenly provided with a plurality of through grooves 44. By providing through grooves 44, the space between the first partition 42 and the second partition 43 can be connected, preventing the air inside the refrigerator body 1 from not circulating, reducing the growth of bacteria, and reducing the weight of the first partition 42 and the second partition 43, thereby reducing the fixing pressure on the first partition 42 and the second partition 43; the inner wall of the slider 45 is threaded with a threaded pin 416, one end of the threaded pin 416 is fixedly connected to an operating block 417, and the outer surface of the operating block 417 is provided with a protrusion. By providing the threaded pin 416, under the action of the operating block 417, Rotating the operating block 417 causes the threaded pin 416 to rotate, which in turn extends and retracts along the inner wall of the slider 45 until one end of the threaded pin 416 abuts against one side of the inner wall of the slide rail 46. This allows the threaded pin 416 to fix the slider 45 and the slide rail 46 under frictional force, thereby fixing the first partition 42 and the second partition 43. This helps prevent the first partition 42 and the second partition 43 from moving downwards under their own weight and pressing down on the kiwi fruit at the bottom. The outer surface of the operating block 417 has protrusions, which increase the frictional force on the outer surface of the operating block 417, providing an anti-slip effect when rotating the threaded pin 416.

[0028] Reference Figure 4 and Figure 5As shown, this embodiment discloses that a hidden groove 418 is provided on one side of the operating block 417, and a threaded pin 416 is disposed inside the hidden groove 418. By providing the hidden groove 418, when one end of the threaded pin 416 abuts against the inner wall of the slide rail 46, the operating block 417 just completely enters the inner wall of the hidden groove 418. At this time, the operating block 417 will not protrude from one side of the slider 45, thus not obstructing the storage of kiwifruit. In addition, the operating block 417 is also provided with a regular hexagonal groove, which facilitates the operation of the operating block 417 after it enters the inner wall of the hidden groove 418. The operating block 417 is adjusted using a hex wrench; a rubber strip 419 is bonded to one side of the inner wall of the slide rail 46. The rubber strip 419 is set at one end of the threaded pin 416. By setting the rubber strip 419, it can replace one side of the slide rail 46 to abut against one end of the threaded pin 416, which helps to prevent the threaded pin 416 from damaging the inner wall of the refrigerator body 1. At the same time, the rubber strip 419 can increase the friction between the threaded pin 416 and the inner wall of the slide rail 46, thereby making it less likely for the threaded pin 416 to loosen its fixation on the first partition 42 and the second partition 43.

[0029] Reference Figure 2 and Figure 3 as well as Figure 8 As shown in the figure, this embodiment discloses that a limiting plate 420 is fixedly connected to the side of the top of the first partition 42 and the second partition 43 that is far apart from each other. One side of the limiting plate 420 abuts against one side of the inner wall of the preservation box body 1, and the outer surface of the airbag 415 is fixedly connected to the other side of the limiting plate 420. By setting the limiting plate 420, which is respectively set on both sides of the first partition 42 and the second partition 43, the first partition 42 and the second partition 43 can be limited to the inner wall of the preservation box body 1, so that the first partition 42 and the second partition 43 can be kept horizontal under normal conditions, which is convenient for placing kiwifruit.

[0030] Reference Figures 8-11As shown, this embodiment discloses that the top of the limiting plate 420 is symmetrically fixedly connected with locking blocks 421. The inner walls of the two locking blocks 421 are fitted with the same rectangular plate 422. By setting the rectangular plate 422 and inserting it into the inner walls of the two locking blocks 421, the locking blocks 421 can limit the rectangular plate 422, and the rectangular plate 422 can limit the distance between the two limiting plates 420. This helps to prevent the first partition 42 and the second partition 43 from bending inward under the influence of vibration during transportation, which would cause damage to the kiwifruit. The bottom of the rectangular rod is fixed. An extension plate 423 is connected, with its bottom abutting against the top of the first partition 42 and the second partition 43. A sponge plate 424 is fixedly connected to the side of the two extension plates 423 that are close to each other. By setting a limiting plate 420, the two sides between the two limiting plates 420 can be limited, which can prevent the kiwi fruit from hitting the gear 47 and other components. At the same time, the sponge plate 424 on one side of the limiting plate 420 can further buffer and protect the side of the two limiting plates 420 that are close to each other, which is conducive to preventing the kiwi fruit that hits the limiting plate 420 from being damaged.

[0031] The working principle is as follows: First, an appropriate amount of ice packs needs to be placed inside the main body 1 of the food storage box. The main body 1 is made of PU, i.e., polyurethane, which has strong heat insulation properties. After placing ice and kiwis inside the main body 1, the sealing lid 2 is then tightly closed. The sealing lid 2, under the action of the sealing ring 3, will seal the main body 1. When there are many kiwis, rotate the first partition 42 or the second partition 43, and place kiwis and ice packs at the bottom of the first partition 42 and the second partition 43. At the same time, kiwis and ice packs can also be placed above the first partition 42 and the second partition 43. This can divide a large number of kiwis into upper and lower parts, and the slider 45 can slide on the inner wall of the slide rail 46. This makes it easy to adjust the position of the first partition 42 and the second partition 43 according to the actual size of the bottom kiwis, so that the first partition 42 and the second partition 43 can bear the weight of the top kiwis without squeezing the bottom kiwis. At this time, rotate the operating block 417. The threaded pin 416 rotates, and the threaded pin 416 extends and retracts on the inner wall of the slider 45 until one end of the threaded pin 416 abuts against the rubber strip 419 on one side of the inner wall of the slide rail 46 and the operating block 417 is fully inserted into the inner wall of the hidden groove 418. Then, the threaded pin 416 can fix the slider 45 and the slide rail 46 under the action of friction, and thus fix the first partition 42 and the second partition 43. This helps to prevent the first partition 42 and the second partition 43 from moving downward under their own weight and pressing down on the bottom kiwi. Then, the rectangular plate 422 is inserted into the inner wall of the two locking blocks 421. The locking blocks 421 can limit the rectangular plate 422, and the rectangular plate 422 can limit the two limiting plates 420. Under the joint action of the limiting plates 420, the first partition 42 and the second partition 43 can be fixed, which can reduce the pressure on the bottom kiwi when there are many kiwis and reduce the damage to the kiwi.When there are few kiwis, place the kiwis and ice packs directly on top of the first partition 42 and the second partition 43, and push the first partition 42 and the second partition 43 downwards. The first partition 42 and the second partition 43 will move the kiwis towards the bottom of the inner wall of the refrigerator body 1, and at the same time, they will move the slider 45 downwards along the inner wall of the slide rail 46. Meanwhile, the rotating shaft 41 will drive the two gears 47 downwards. As the gears 47 move downwards, they will rotate continuously under the action of the toothed plate 48. The first pulley 49 connected to the gear 47 will drive the transmission belt 410 to move, and the transmission belt 410 will in turn drive the second... The rotation of the second pulley 411 drives the threaded rod 412 to rotate, which in turn drives the pusher block 414 to slide against the inner wall of the air chamber 413. The air chamber 413 is made of rigid material. When the pusher block 414 pushes, it pushes the air in the air chamber 413 into the air bladder 415, causing the air bladder 415 to inflate. The further the first partition 42 and the second partition 43 move downwards, the larger the air bladder 415 inflates. The inflated air bladder 415 reduces the movement range of the kiwi fruit and protects it from damage when it impacts the air bladder 415, thus preventing damage when the kiwi fruit is small.

2. A method for preserving and transporting kiwifruit, characterized in that: Using the kiwifruit preservation and transportation equipment described in claim 1, firstly, an appropriate amount of ice packs needs to be placed inside the preservation box body (1). The preservation box body (1) is made entirely of PU, i.e., polyurethane material, which has strong heat insulation properties. After placing the ice and kiwifruit inside the preservation box body (1), the sealing cover (2) is then tightly closed. The sealing cover (2) will seal the preservation box body (1) under the action of the sealing ring (3). When there are many kiwifruit, the first partition (42) or the second partition (43) is rotated, and the first partition (42) and the second partition (43) are rotated. Kiwis and ice packs are placed at the bottom of partition 43), and kiwis and ice packs can also be placed above the first partition (42) and the second partition (43). This allows a large number of kiwis to be divided into upper and lower parts, and the slider (45) can slide on the inner wall of the slide rail (46). This makes it easy to adjust the position of the first partition (42) and the second partition (43) according to the actual size of the bottom kiwis, so that the first partition (42) and the second partition (43) can bear the weight of the top kiwis without squeezing the bottom kiwis. At this time, the operating block (4) is rotated. 17) Drive the threaded pin (416) to rotate. The threaded pin (416) will extend and retract on the inner wall of the slider (45) until one end of the threaded pin (416) abuts against the rubber strip (419) on one side of the inner wall of the slide rail (46) and the operating block (417) is completely inserted into the inner wall of the hidden groove (418). Then the threaded pin (416) can fix the slider (45) and the slide rail (46) under the action of friction, and thus fix the first partition (42) and the second partition (43), which helps to prevent the first partition (42) and the second partition (43) from being separated. 3) The kiwi moves downward under its own weight and is pressed to the bottom layer. Then, the rectangular plate (422) is inserted into the inner wall of the two blocks (421). The blocks (421) can limit the rectangular plate (422), and the rectangular plate (422) can limit the two limiting plates (420). Under the joint action of the limiting plates (420), the first partition (42) and the second partition (43) can be fixed, which can reduce the pressure on the bottom kiwi and reduce the damage to the kiwi to a certain extent when there are many kiwis.When there are few kiwis, place the kiwis and ice packs directly on top of the first partition (42) and the second partition (43), and push the first partition (42) and the second partition (43) downwards. The first partition (42) and the second partition (43) will move the kiwis to the bottom of the inner wall of the refrigerator body (1), and at the same time, they will move the slider (45) downwards on the inner wall of the slide rail (46). Meanwhile, the rotating shaft (41) will drive the two gears (47) downwards. When the gears (47) move downwards, they will rotate continuously under the action of the toothed plate (48). The first pulley (49) connected to the gears (47) will drive the transmission belt (410) to move, and the transmission belt (410) will then drive the transmission belt (410) to move. The second pulley (411) rotates, which drives the threaded rod (412) to rotate. The threaded rod (412) drives the pusher (414) to slide on the inner wall of the air chamber (413). The air chamber (413) is made of rigid material. When the pusher (414) pushes, it pushes the air in the air chamber (413) into the airbag (415), causing the airbag (415) to expand. The more the first partition (42) and the second partition (43) move downward, the larger the airbag (415) expands. The expanded airbag (415) reduces the movement range of the kiwifruit and can protect the kiwifruit when it hits the airbag (415), thus preventing damage when there are few kiwifruit.
