[0045] like Figure 1-10As shown, an embodiment of the present application provides a protective device applied to a storage device, wherein a multi-layer shelf 2 is movably arranged in a box 1 of the storage device along a first direction X; the protective device includes: a plurality of support units 3 and a connection unit 4.

[0046] Multiple support units 3 are spaced apart along the first direction X. Each support unit 3 is provided with a limiting portion 31 for limiting the position of the shelf 2. Specifically, the limiting portion 31 may be provided on the support unit 3 to limit the position of the shelf 2, or the limiting portion 31 may not be provided, that is, the support unit 3 only serves to increase the length of the protective device in the first direction X.

[0047] Two ends of the connection unit 4 along the first direction X are respectively connected to two adjacent support units 3 , and the length of the connection unit 4 along the first direction X is adjustable.

[0048] In the present application, the distance between two adjacent support units 3 is adjusted by adjusting the length of the connecting unit 4 along the first direction X, so that the limiting portion 31 on different support units 3 can limit the shelves 2 with different spacings in the first direction X, which can be applicable to refrigerators of different sizes and specifications, thereby improving versatility.

[0049] Specifically, the storage device in the present application can be a refrigerator, or other storage device with multiple layers of shelves 2 inside, and the shelves 2 need to be protected, such as a multi-layer movable support plate for a storage box, which can also be packaged and fixed by the protective device in the present application.

[0050] The first direction X in this application is the vertical direction, because the shelves 2 in the refrigerator are spaced apart in the vertical direction and the shelves 2 slide in the slides in the refrigerator body 1, and there is a gap between the shelves 2 and the slides. During transportation, the shelves 2 may bump against the slides due to bumps and shaking, which may easily cause damage to the shelves 2.

[0051] Optionally, the first direction X in the present application can also be other directions. For some storage devices, the shelf 2 is inserted vertically into the box body 1 or inserted obliquely downward into the box body 1. The shelf 2 can also be packaged and fixed by the protective device in the present application.

[0052] In the related art, the protective devices for the shelves 2 during transportation of refrigerators are currently designed for specific refrigerators. However, refrigerators have different sizes and specifications, which results in differences in the spacing between the shelves 2. The existing protective devices can only package and fix the shelves 2 with the same spacing, resulting in poor versatility.

[0053] In the embodiment of the present application, the spacing between the support units 3 can be adjusted by adjusting the length of the connecting unit 4 according to the specific spacing between the shelves 2, and then the spacing of the limiting parts 31 on different supporting panels can be adjusted, so that the limiting parts 31 on different support units 3 can provide limited support for shelves 2 with different spacings, which can be applicable to shelves 2 with different spacings and refrigerators of different sizes, thereby improving applicability.

[0054] In some embodiments, the connecting unit 4 includes: an extending portion 41, the two ends of the extending portion 41 are respectively connected to two adjacent support units 3, and the extending portion 41 can be extended and retracted along the first direction X; and a fixing portion 42, one end of the fixing portion 42 is detachably connected to one of the two adjacent support units 3, and the other end is movably connected or detachably connected to the other of the two adjacent support units 3, for fixing the length of the connecting unit 4 along the first direction X.

[0055] In the present application, the two ends of the extending portion 41 connect two adjacent support units 3. By extending and retracting, the distance between the two adjacent support units 3 is changed. Furthermore, the protective device is limited in the first direction X, so that the protective device can only be extended and retracted along the first direction X, thereby ensuring the structural stability of the protective device and its ability to secure the shelf 2. After the length of the extending portion 41 is adjusted, the fixing portion 42 effectively connects the two adjacent support units 3, thereby fixing the length of the connecting unit 4 and ensuring that the protective device effectively secures the shelves 2 at different spacings.

[0056] In a specific embodiment, one end of the fixing portion 42 is detachably connected to one of the two adjacent support units 3, and the other end is movably connected to the other of the two adjacent support units 3. The fixing portion 42 can be bent or rotated through the movably connected end, and is connected to the support unit 3 through the detachable end to achieve length locking of the connecting unit 4.

[0057] In another specific embodiment, the two ends of the fixing portion 42 are detachably connected to the two adjacent support units 3, that is, after adjusting the length of the extending portion 41, the two ends of the fixing portion 42 are respectively connected to the two adjacent support units 3 to provide a supporting effect, thereby completing the locking of the length of the connecting unit 4.

[0058] Optionally, multiple support units 3 adopt a split design, and the connecting unit 4 is detachably connected to the support unit 3. Two adjacent support units 3 are connected through the connecting unit 4, and the distance between the two adjacent support units 3 is adjusted by adjusting the connection position. For example, multiple connecting parts connected to the connecting unit 4 are provided on the support unit 3, and the multiple connecting parts are arranged at intervals along the first direction X. By connecting one end of the connecting unit 4 to a connecting part of one of the two support units 3 and the other end of the connecting unit 4 to the first connecting part of the other of the two support units 3, an effective connection of the two support units 3 is achieved, and the distance between the two support units 3 can be adjusted by selecting to connect the connecting unit 4 to different connecting parts.

[0059] Optionally, multiple support units 3 adopt a split design, with one end of each connecting unit 4 being movably connected to one of two adjacent support units 3 and the other end being detachably connected to the other of the two adjacent support units 3. The end of the connecting unit 4 detachably connected to the support unit 3 serves to adjust the length of the connecting unit 4. Unlike the above-mentioned embodiment, the connecting unit 4 in the present application may not have an extending portion 41, but only a fixing portion 42. For example, multiple connecting portions may be provided on the support unit 3, and the multiple connecting portions may be spaced apart along the first direction X. By connecting the fixing portion 42 of the connecting unit 4 to different connecting portions, the effective length of the connecting unit 4 connected to the protective device can be adjusted.

[0060] In some embodiments, the extending portion 41 and the fixing portion 42 are spaced apart around the circumference of the connecting unit 4 .

[0061] In the present application, the extending portion 41 ensures that the connecting unit 4 can only be extended and retracted along the first direction X, and the fixing portion 42 is used to lock the length of the connecting unit 4 in the first direction X. By arranging the extending portion 41 and the fixing portion 42 at circumferential intervals around the connecting unit 4, the stability and supporting strength of the connecting unit 4 structure are ensured, thereby ensuring the packaging fixing effect of the shelf 2.

[0062] Specifically, the cross section of the connecting unit 4 can be a hexagonal structure, wherein three faces are extended portions 41 and the other three faces are fixed portions 42, and the three extended portions 41 and the three fixed portions 42 are arranged at intervals. Alternatively, the cross section of the connecting unit 4 can also be an octagonal structure, a quadrilateral structure, etc.

[0063] In a specific embodiment, the connecting unit 4 includes two extending portions 41 and two fixing portions 42 . The two extending portions 41 are disposed opposite to each other, and the two fixing portions 42 are disposed opposite to each other.

[0064] In this application, the cross-section of the connecting unit 4 is a quadrilateral structure. By arranging the two extending parts 41 relative to each other and the two fixing parts 42 relative to each other, the connecting unit 4 is subjected to force more evenly and the force is balanced along the first direction X, thereby further improving the stability and support strength of the connecting unit 4 structure.

[0065] Optionally, the extension portion 41 can also be a telescopic sleeve. The telescopic sleeve is an outer tube and an inner tube that are nested with each other. The inner tube can slide along the axial direction of the outer surface and is limited when it slides to the maximum length. The outer tube has a socket for inserting the inner tube. The end of the outer tube away from the socket is connected to one of the two adjacent support units 3. The inner tube has an insertion end inserted into the above-mentioned socket. The end of the inner tube away from the insertion end is connected to the other of the two adjacent support units 3. By adjusting the length of the inner tube in the outer tube, the overall length of the connecting unit 4 is adjusted, and thus the distance between the two adjacent support units 3 is adjusted. In addition, the form of the telescopic sleeve can ensure that the protective device can only be extended and retracted along the first direction X, thereby ensuring the stability of the protective device structure. After the length of the connecting unit 4 is adjusted, the two adjacent support units 3 are locked by the fixing portion 42, so that the entire protective device becomes a three-dimensional structure with a stable structure.

[0066] In another optional embodiment, the connecting unit 4 may not have the extending portion 41, and the connection and distance adjustment between two adjacent support units 3 may be achieved through the four fixing portions 42 on the periphery. For example, each of the four fixing portions 42 may be connected to a support unit 3 at one end and detachably connected to another support unit 3 at the other end. By adjusting the position of the detachable connection between the fixing portion 42 and the support unit 3, the distance between two adjacent support units 3 can be adjusted.

[0067] In some embodiments, a plurality of slots 32 are provided along the first direction X at one end of the support unit 3 adjacent to the connection unit 4 . One end of the fixing portion 42 is connected to one of the two adjacent support units 3 , and the other end is plugged into one of the slots 32 .

[0068] In the present application, multiple slots 32 are provided on the support unit 3, and the multiple slots 32 are spaced apart along the first direction X. By plugging the ends of the fixing portion 42 into different slots 32, the lengths of the connecting units 4 of different lengths can be locked. This plug-in connection method facilitates the connection between the fixing portion 42 and the support unit 3 and ensures the reliability of subsequent connections.

[0069] Specifically, the spacing and number of the slots 32 are set according to the spacing of the existing shelves 2, that is, the spacing of the shelves 2 in the existing refrigerator is several specific levels, and the slots 32 are designed with several levels, and the several levels correspond to the spacing of the shelves 2 of several levels.

[0070] Optionally, a plurality of fixing grooves may be provided on the fixing portion 42 along the first direction X, and an inserting portion may be provided on the supporting unit 3. By inserting the inserting portion into different fixing grooves, the lengths of the connecting units 4 of different lengths can also be locked.

[0071] In another optional embodiment, the fixing portion 42 and the support unit 3 are detachably connected via fasteners. For example, the support unit 3 is provided with multiple adjustment holes spaced apart along the first direction X. The fixing portion 42 is connected to different adjustment holes via fasteners, thereby locking the length of the connection unit 4 at different lengths, thereby ensuring the stability of the three-dimensional structure of the protective device. Specifically, the fasteners may be screws, press buckles, etc.

[0072] In another optional embodiment, the fixing portion 42 and the support unit 3 are detachably connected by a snap-fit. For example, a plurality of first snap-fit portions are provided on the support unit 3, and the plurality of first snap-fit portions are spaced apart along the first direction X. A second snap-fit portion is provided on the fixing portion 42. By snapping the second snap-fit portion on the fixing portion 42 with different first snap-fit portions, the length locking of the connection units 4 that are not in different length states is achieved, thereby ensuring the stability of the three-dimensional structure of the protective device.

[0073] In another optional embodiment, the fixing portion 42 and the support unit 3 can also be detachably connected by a fastening bolt. Specifically, a strip hole extending along the first direction X is provided on the support unit 3. The fastening bolt is provided on the fixing portion 42 and can be locked with the strip hole. When the length of the connecting unit 4 needs to be adjusted, the fastening bolt is loosened so that the fixing portion 42 can slide along the strip hole. After adjusting to the desired position, the fastening bolt is tightened so that the fastening bolt is fastened to the strip hole portion of the support unit 3. Continuous adjustment of the length of the connecting unit 4 can be achieved, and shelves 2 with more spacing conditions can be packaged and fixed, which can further improve applicability.

[0074] In some embodiments, the width of the fixing portion 42 is gradually reduced in a direction toward the slot 32 , the narrowest width of the fixing portion 42 is smaller than the width of the slot 32 , and the widest width of the fixing portion 42 is larger than the width of the slot 32 .

[0075] In the present application, the narrowest width of the fixing portion 42 is smaller than the width of the slot 32, so that the end of the fixing portion 42 can be inserted into the slot 32. As the depth of the end of the fixing portion 42 inserted into the slot 32 increases, the portion where the width of the fixing portion 42 is equal to the width of the slot 32 can complete the clamping of the fixing portion 42, thereby completing the locking of the distance between two adjacent support units 3.

[0076] The maximum width of the fixing portion 42 is equal to the width of the support unit 3 , and the connection length between the fixing portion 42 and the support unit 3 is increased as much as possible to ensure the reliability of the connection between the fixing portion 42 and the support unit 3 .

[0077] Specifically, the first direction X in this application is the vertical direction, the shelf 2 is arranged horizontally, and the protective device is provided on one side of the multi-layer shelf 2. The support unit 3 primarily supports the shelf 2, thereby preventing the shelf 2 from colliding with the relatively hard refrigerator housing 1 due to bumps and shakes during transportation. Moreover, after the fixing portion 42 is plugged into the slot 32, friction prevents the fixing portion 42 from separating from the slot 32, thereby limiting the position of the shelf 2 from both the upper and lower directions, further ensuring the packaging and fixing effect of the shelf 2.

[0078] like Figure 7 As shown, in another embodiment, the fixing portion 42 can also be designed to be of equal width, and tooth structures 423 are provided at both ends of the fixing portion 42 in the width direction. When the fixing portion 42 is inserted into the slot 32, the tooth structure 423 and the slot 32 are used to limit the connection unit 4, so that the connection unit 4 can be stably maintained at a specific length. Moreover, the tooth structure 423 can also realize continuous adjustment of the effective length of the connection unit 4, and can package and fix shelves 2 with more spacing conditions, which can further improve applicability.

[0079] like Figure 8 As shown, in another embodiment, the fixing portion 42 is designed to be of equal width, and a toothed structure 423 is provided on the outer surface of the fixing portion 42, and an engaging tooth 35 cooperating with the toothed structure 423 is provided on the inner side of the slot 32. The engaging tooth 35 is located on the inner side wall of the support unit 3 and adjacent to the slot 32. The fixing portion 42 causes the toothed structure 423 to engage with the engaging tooth 35 under the action of its own elastic force. When it is necessary to continue to adjust the length of the connecting unit 4, the fixing portion 42 is pressed inward through the slot 32 to separate the toothed structure 423 from the engaging tooth 35, and then the length of the fixing portion 42 inserted into the slot 32 can be continued to be adjusted. After adjusting to the desired position, the fixing portion 42 is released, and the fixing portion 42 is reset under its own elastic force, so that the toothed structure 423 engages with the engaging tooth 35 again, completing the locking of the length of the connecting unit 4.

[0080] like Figure 9 As shown, in another embodiment, a plug 421 is provided on the fixing portion 42 , and the plug 421 is used to be inserted into the slot 32 to keep the connecting unit 4 at a current length.

[0081] In the present application, a plug 421 can be provided at the end of the fixing portion 42, or a plug 421 can be provided somewhere on the fixing portion 42. The plug 421 is provided perpendicular to the surface where the fixing portion 42 is located, and the plug 421 is inserted into the slot 32 in the horizontal direction, thereby playing a supporting and limiting role. The shelf 2 can be limited in both the upper and lower directions, thereby ensuring the packaging fixing effect of the shelf 2.

[0082] Specifically, the plug 421 and the fixing portion 42 here need to be configured in a fixed connection form to ensure that the plug 421 can effectively resist the gravity of the shelf 2 in the vertical direction after being inserted into the slot 32.

[0083] In some embodiments, the extending portion 41 includes at least two folding plates 411 connected in sequence along the first direction X, and the two ends of the at least two folding plates 411 along the first direction X are movably connected to the two adjacent support units 3 respectively, and the two adjacent folding plates 411 are movably connected to each other.

[0084] In the present application, the extension portion 41 includes multiple folding plates 411 connected in sequence. The top folding plate 411 is movably connected to the support unit 3 above it, and the bottom folding plate 411 is movably connected to the support unit 3 below it. The two adjacent folding plates 411 are movably connected, so that the folding plates 411 can be bent along the movable connection, thereby realizing the adjustment of the length of the extension portion 41. The extension portion 41 can limit the protective device so that the protective device can only be extended and retracted along the first direction X.

[0085] Specifically, there are two folding plates 411, one of which is connected to the upper support unit 3, and the other is connected to the lower support unit 3, with the two folding plates 411 being movably connected. The two folding plates 411 are integrally structured, with a folding line 412 provided between the two folding plates 411. The two folding plates 411 can be folded along the folding line 412, which is perpendicular to the first direction X. The folding line 412 also allows folding between the folding plates 411 and the support unit 3.

[0086] In some embodiments, the limiting portion 31 is a slot 311 for one side of the shelf 2 to be inserted into.

[0087] In the present application, one side of the shelf 2 is inserted into the card slot 311, thereby completing the limitation of this side of the shelf 2. Specifically, the shelf 2 is placed in the refrigerator body 1, and the rear of the shelf 2 is fixed by the slide groove in the refrigerator body 1, and the protective device fixes the front side of the shelf 2.

[0088] Specifically, the number of protective devices can be one or more. For a shelf 2 with a smaller horizontal length, one protective device can be set in the middle of the shelf 2. For a shelf 2 with a larger horizontal length, two or more protective devices can be set on the front side of the shelf 2.

[0089] The width of the slot 311 along the first direction X is consistent with the thickness of the shelf 2. When one side of the shelf 2 is inserted into the slot 311, the upper and lower surfaces of the slot 311 fully conform to the upper and lower surfaces of the shelf 2, thereby effectively securing the shelf 2. Specifically, the protective device can be made of a material with a certain cushioning property, such as cardboard. The width of the slot 311 can be set to be slightly smaller than the thickness of the shelf 2, allowing the side of the shelf 2 to be inserted into the slot 311 by squeezing.

[0090] Optionally, a protective rubber strip may be provided in the slot 311, and the protective rubber strip may be attached to the upper and lower surfaces of the shelf 2 to further enhance the protection effect on the shelf 2. The protective rubber strip may be a sponge or a rubber strip.

[0091] In some embodiments, a drawer 5 and an inner wall opposite to the drawer 5 are provided in the box body 1, and an insert plate 6 and an abutment plate 7 are respectively provided at both ends of the protective device along the first direction X. The insert plate 6 is used to be inserted into the gap of the drawer 5, and the abutment plate 7 is used to abut the inner wall to fix the protective device in the box body 1.

[0092] In this application, a drawer 5 is provided in the refrigerator body 1, and the drawer 5 is located below the multi-layer shelf 2. When installing the protective device, the plug plate 6 at the bottom of the protective device is inserted into the gap of the drawer 5 to fix the bottom of the protective device. The top of the protective device is abutted against the inner wall of the box body 1 through the abutment plate 7 to fix the top of the protective device, thereby ensuring that the position of the protective device in the box body 1 is fixed, and further ensuring that the protective device can effectively support and limit the shelf 2.

[0093] Specifically, when connecting the inserting plate 6 to the drawer 5, the drawer 5 needs to be pulled out to form a gap, the inserting plate 6 is then inserted into the gap, and the drawer 5 is closed to complete the fixing of the inserting plate 6. By adjusting the length of the connecting unit 4 so that the height of the entire protective device is equal to the distance between the drawer 5 and the inner wall, the protective device can be effectively fixed in the box body 1, thereby limiting the vertical position of the shelf 2.

[0094] Specifically, the abutment plate 7 is the top plane of the protective device, and after being fitted with the inner wall of the box body 1 , it can ensure the stability of the protective device being fixed in the box body 1 .

[0095] Optionally, the bottom of the protective device can also directly abut against the inner bottom wall of the box body 1, and the top of the protective device can abut against the inner top wall of the box body 1, thereby completing the fixation of the protective device in the box body 1, and allowing the protective device to effectively limit the shelf 2.

[0096] In some embodiments, a bottom cover 8 is provided at one end of the protective device adjacent to the inserting plate 6 , and the bottom cover 8 is used to abut against a side of the drawer 5 away from the inserting plate 6 .

[0097] In the present application, the bottom cover 8 is used to seal the bottom opening of the protective device on the one hand, thereby ensuring the structural strength of the bottom of the protective device. On the other hand, the bottom cover 8 can also abut against the side of the drawer 5 away from the insert plate 6. The bottom cover 8 and the insert plate 6 sandwich the side wall of the drawer 5 in the middle, thereby effectively fixing the bottom of the protective device to the drawer 5, further ensuring the reliability of the connection between the protective device and the drawer 5.

[0098] In some embodiments, the protective device is formed by folding a one-piece plate into a hollow cylindrical structure.

[0099] In this application, the protective device is a hollow cylindrical structure, which saves raw materials and reduces production costs while ensuring its own structural strength. The protective device is formed by folding a single piece of sheet material into a hollow cylindrical structure, which is convenient for processing and assembly. It only needs to process the required fold lines 412, openings, etc. on the flat sheet material, and then fold the sheet material into shape.

[0100] Specifically, the protective device is a hollow quadrangular prism structure. A slot 311 is provided on one side of the support unit 3 for one side of the shelf 2 to be inserted into. Two opposite sides of the connecting unit 4 are extending parts 41, and the other two opposite sides are fixing parts 42.

[0101] In a specific embodiment, the protective device is made of cardboard. The folding plate 411 of the connecting unit 4 and the support unit 3, as well as between two adjacent folding plates 411, are folded by pre-stressed folding lines 412. One end of the fixing portion 42 is folded with the support unit 3 by the pre-stressed folding line 412, and the other end is connected to the support unit 3 by a tear line 422. During assembly, the fixing portion 42 can be torn along the tear line 422 to separate the fixing portion 42 from the support unit 3, and then the end of the fixing portion 42 can be inserted into the required slot 32. In actual use, if the height of the protective device is just right, the tear line 422 does not need to be torn. The two ends of the fixing portion 42 are respectively connected to the two adjacent support units 3 to form a whole. The protective device is fixed in the box body 1, and then the slot 311 on the support unit 3 is used to limit the position of one side of the shelf 2. If the height of the protective device is not appropriate, the spacing between the shelf 2 and the top of the refrigerator inner tank, the spacing between adjacent shelves 2, and the distance between the shelf 2 and the bottom of the refrigerator changes, it is necessary to tear the corresponding tear line 422, insert the end of the fixing part 42 into the appropriate slot 32, and adjust the effective length of the connecting unit 4. The length adjustment is achieved by folding the folding plate 411 inward along the folding line 412 to achieve the effect of lowering the height. When it is lowered to the required position, the bottom end of the fixing part 42 is inserted from the outside to the inside into the appropriate slot 32 to complete the adjustment of the overall height of the protective device and the position of each limiting part 31, so that the protective device can be just installed in the refrigerator body 1, and multiple limiting parts 31 can limit multiple shelves 2 respectively.

[0102] Specifically, when the cardboard is in the unfolded state, the slots 32 are strip-shaped grooves distributed on the sides of the three support units 3. The strip-shaped grooves extend in the horizontal direction. After the cardboard is assembled, a slot 32 with a certain depth is formed to ensure that one side of the shelf 2 can be inserted into the slot 32 to a certain depth, thereby ensuring the limiting effect of the shelf 2.

[0103] In another specific embodiment, the protective device can also be a plastic sheet. The plastic sheet has a certain supporting strength. The folding plate 411 of the connecting unit 4 and the supporting unit 3 and the two adjacent folding plates 411 are folded by a folding line 412. One end of the fixing portion 42 is folded with the supporting unit 3 by the folding line 412, and the other end is directly cut into a form separated from the supporting unit 3. During assembly, the end of the fixing portion 42 can be inserted into the required slot 32.

[0104] In some embodiments, a lock buckle 33 and a lock opening 34 are provided on the side wall of the support unit 3 , and the protective device is plugged into the lock buckle 33 and the lock opening 34 to form a hollow columnar structure.

[0105] In the present application, the plate material that encloses the protective device includes five sides, one of which is provided with a lock buckle 33, and one of which is provided with a lock opening 34. The lock opening 34 and the lock buckle 33 are farthest apart when the plate material is in the unfolded state, and the lock buckle 33 and the lock opening 34 are provided in a one-to-one correspondence. After the plate material is folded into a hollow columnar structure, the protective device has four sides, wherein the side with the lock buckle 33 is fitted together with the side with the lock opening 34. By inserting the lock buckle 33 into the lock opening 34, the locking of the two sides is completed, so that the protective device includes maintaining a three-dimensional structure to protect the shelf 2.

[0106] Specifically, two of the five side surfaces are provided with an extension portion 41, two side surfaces are provided with a fixing portion 42, and the last side surface is provided with a locking opening 34. The side surface with the locking opening 34 is disconnected at the position of the connecting unit 4, that is, the side surface with the locking opening 34 only exists in the supporting unit 3, not in the connecting unit 4, and will not hinder the connecting unit 4 from extending and retracting.

[0107] The protective device adjusts the distance between two adjacent support units 3 by adjusting the length of the connecting unit 4 along the first direction X, so that the limiting parts 31 on different support units 3 can limit the shelves 2 with different spacings in the first direction X. It can be applied to refrigerators of different sizes and specifications, thereby improving versatility.

[0108] The connecting unit 4 includes an extending portion 41 and a fixing portion 42. The extending portion 41 is respectively connected to two adjacent support units 3 at both ends, and the extending portion 41 is extendable and retractable along a first direction X. The fixing portion 42 has one end detachably connected to one of the two adjacent support units 3 and the other end movably or detachably connected to the other of the two adjacent support units 3, thereby fixing the length of the connecting unit 4 along the first direction X. The extending portion 41 connects the two adjacent support units 3 at both ends, and by extending and retracting itself, it changes the distance between the two adjacent support units 3. It also limits the position of the protective device in the first direction X, allowing the protective device to extend and retract only along the first direction X, thereby ensuring the structural stability of the protective device and its ability to secure the shelf 2. After the length of the extending portion 41 is adjusted, the fixing portion 42 effectively connects the two adjacent support units 3, thereby fixing the length of the connecting unit 4 and ensuring that the protective device effectively secures the shelves 2 at different spacings.

[0109] Specifically, the protective device in the present application is provided with four support units 3, wherein two adjacent support units 3 among the four support units 3 form a connection, and the protective device is provided with three connection units 4, which are respectively provided at the three connection points to connect the support units 3. The two middle support units 3 are provided with limiting portions 31 to limit the two layers of shelves 2 in the box body 1. The uppermost support unit 3 and the lowermost support unit 3 are not provided with limiting portions 31, because two layers of shelves 2 are generally provided in the refrigerator, and the limiting portions can be achieved by the two middle limiting portions 31. The support units 3 at the two ends are not provided with limiting portions 31, which can further ensure the strength of the overall structure of the protective device.

[0110] Figure 11 A schematic structural diagram of a storage device provided in an embodiment of the present application is shown.

[0111] like Figure 11 As shown, an embodiment of the present application provides a storage device, comprising: a box body 1, in which a multi-layer shelf 2 is movably arranged along a first direction X; and the above-mentioned protective device.

[0112] In the present application, the storage device is a refrigerator, and the refrigerator body 1 is provided with multi-layer shelves 2. The multi-layer shelves 2 are inserted into the body 1 in a vertical direction. During transportation, the glass shelves 2 are easily bumped and swayed against the body 1, causing damage to the shelves 2. By adopting the protective device of the present application, the distance between two adjacent support units 3 can be adjusted by adjusting the length of the connecting unit 4 along the first direction X, so that the limiting parts 31 on different support units 3 can limit the shelves 2 with different spacings in the first direction X. This can be applied to refrigerators of different sizes and improves versatility.

[0113] Specifically, when installing the protective device, first adjust the effective length of the connecting unit 4 connected to the protective device according to the spacing between the shelves 2, so as to adjust the spacing between the two adjacent support units 3, and the position of the limiting portion 31 on the support unit 3 is adjusted synchronously, so that the distance between the two limiting portions 31 is consistent with the distance between the shelves 2, and then fix the protective device in the vertical direction inside the box body 1, and limit one side of the shelf 2 by the limiting portion 31 on the support unit 3, thereby preventing the shelf 2 from shaking in the vertical direction, reducing or even avoiding the collision between the shelf 2 and the box body 1 due to bumps and shaking during transportation of the refrigerator, and protecting the shelf 2.

[0114] The protective device is made of cardboard. The folding plate 411 of the connecting unit 4 and the support unit 3, as well as the two adjacent folding plates 411, are folded by pre-stressed folding lines 412. One end of the fixing portion 42 is folded with the support unit 3 by the pre-stressed folding line 412, and the other end is connected to the support unit 3 by a tear line 422. During assembly, the fixing portion 42 can be torn along the tear line 422 to separate the fixing portion 42 from the support unit 3, and then the end of the fixing portion 42 can be inserted into the required slot 32. In actual use, if the height of the protective device is just right, the tear line 422 does not need to be torn. The two ends of the fixing portion 42 are respectively connected to the two adjacent support units 3 to form a whole. The protective device is fixed in the box body 1, and then the slot 311 on the support unit 3 is used to limit the position of one side of the shelf 2. If the height of the protective device is not appropriate, and the spacing between the shelf 2 and the top of the refrigerator liner, the spacing between adjacent shelves 2, or the spacing between the shelf 2 and the bottom of the refrigerator changes, it is necessary to tear the corresponding tear line 422 and insert the end of the fixing portion 42 into the appropriate slot 32 to adjust the effective length of the connecting unit 4. The length adjustment is achieved by folding the folding plate 411 inward along the folding line 412 to achieve the effect of lowering the height. When it is lowered to the required position, the bottom end of the fixing portion 42 is inserted from the outside to the inside into the appropriate slot 32 to complete the adjustment of the overall height of the protective device and the position of each limiting portion 31. This allows the protective device to be installed precisely within the refrigerator body 1 and multiple limiting portions 31 can respectively limit the position of multiple shelves 2. This can effectively reduce the material cost and assembly cost of the protective device. When it is later applied to the refrigerator, it can be adjusted according to the actual size specifications of the refrigerator to suit different refrigerators. In addition, the cardboard itself has a certain cushioning property. After one side of the shelf is inserted into the slot, the shelf can be packaged and protected by the cushioning property of the cardboard, without the need for a separate cushioning layer.

[0115] The protective device can also be made of a plastic sheet. The plastic sheet has a certain supporting strength. The folding plate 411 of the connecting unit 4 and the supporting unit 3 and the two adjacent folding plates 411 are folded by a folding line 412. One end of the fixing portion 42 is folded with the supporting unit 3 by the folding line 412, and the other end is directly cut to be separated from the supporting unit 3. During assembly, the end of the fixing portion 42 can be inserted into the required slot 32. After the plastic sheet is enclosed into a hollow columnar structure, it can be bonded to form a stable three-dimensional structure. Compared with cardboard materials, the supporting strength of plastic sheet is higher. In order to provide a protective effect for the shelf, a buffer layer can be set at the card slot. When one side of the shelf is inserted into the card slot, it fits up and down with the buffer layer to improve the buffering effect between the shelf and the shelf, thereby packaging and fixing the shelf.

[0116] Of course, the storage device can also be other storage devices with multi-layer shelves 2 inside and the shelves 2 need to be protected, such as multi-layer movable support plates placed on storage boxes, which can also be packaged and fixed by the protective device in this application.

[0117] The protective device can adjust its own height and the spacing of the supporting components to adapt to different refrigerator heights, thereby improving the versatility of the protective device and further reducing the need for designers to redesign the protective device due to differences in refrigerator heights. At the same time, the versatility also reduces a certain amount of R&D costs and has a wider range of uses.
