Furthermore, the storage rack is also a telescopic rack with a telescopic mechanism, allowing users to flexibly adjust its size according to their needs, thus enhancing its versatility.

[0010] The specific structure of the telescopic mechanism is improved. The storage rack is a rectangular frame. The telescopic mechanism includes hollow columns located at the four corners of the upper frame and support columns located at the four corners of the lower frame. Each support column is inserted into each hollow column, and each support column can move synchronously on each hollow column.

[0011] The above technical solution has the following advantages or beneficial effects:

[0012] The lower frame can move synchronously within the hollow columns of the upper frame via various support columns, allowing the lower frame to contract or expand on the upper frame, thereby adjusting the volume of the storage shelf.

[0013] In one embodiment, the hollow column is provided with a plurality of adjustment holes, which are arranged in an orderly manner along the length of the hollow column; the support column is provided with elastic buckles for selectively engaging with the adjustment holes.

[0014] The above technical solution has the following advantages or beneficial effects:

[0021] The simple structure effectively ensures the structural strength of the upper frame and allows the suction cups on the four hollow columns at the corners of the upper frame to be simultaneously attached to the mounting carrier, effectively ensuring the installation stability of the storage rack.

[0022] The structure of the lower frame is improved. The lower frame includes a second back rail, two second side rails on both sides, and a base plate. The four corners of the base plate are connected to the support columns. The second back rail is offset from the first back rail on the upper frame. The two second side rails on both sides are offset from the first side rails on both sides of the upper frame.

[0023] The above technical solution has the following advantages or beneficial effects:

[0024] The back rails and side rails of the upper and lower frames can avoid each other, allowing the lower frame to move smoothly in and out of the upper frame, thus flexibly adjusting the overall size of the storage rack.

[0025] In one embodiment, the second back rail and the second side rail are both vertically connected to the base plate, and the lengths of the second back rail and the second side rail are respectively less than the distance between two adjacent hollow columns on the upper frame.

[0026] The above technical solution has the following advantages or beneficial effects:

[0027] The second back panel of the lower frame and the second side panels on both sides are designed to avoid interfering with the position of the hollow column of the upper frame, ensuring the operability of adjusting the size of the storage shelf.

[0028] In one embodiment, the two ends of the second back rail and the two ends of the second side rail are respectively connected to the adjacent support columns, and each of the hollow columns of the upper frame is provided with a groove for the second back rail or the second side rail to slide into.

[0029] The above technical solution has the following advantages or beneficial effects:

[0030] The second back panel and second side panel, connected to the support columns, can slide into the grooves of the hollow columns of the upper frame. This ensures the operability of adjusting the size of the storage shelf, while also utilizing the grooves on the hollow columns to guide and improve the accuracy of the adjustment operation.

[0031] The structure of the suction cup is improved by including a hook, which is mounted on the suction cup via a pivot and can be flipped outward to fasten to the shelf.

[0032] The above technical solution has the following advantages or beneficial effects:

[0033] By adding movable hooks to the suction cups, the storage rack can be simultaneously secured to the shelf using the hooks, thus increasing the auxiliary fixing structure and effectively improving the fixing effect of the storage rack.

[0034] In one embodiment, the edge of the shelf is provided with a binding edge for the hook to fasten, and the shape of the binding edge matches the hook.

[0035] The above technical solution has the following advantages or beneficial effects:

[0036] For shelves with smooth surfaces, which affect the stability of the hooks, adding edging to the edges of the shelves can improve the fixing effect of the hooks.

[0037] In a second embodiment, this application also provides a refrigerator, comprising:

[0038] The container has a compartment with an opening for taking out and putting in.

[0039] Shelves, which are removable from the box, are used to divide the compartment into multiple storage spaces;

[0043] The beneficial effects of the storage rack and refrigerator provided in this application are as follows: Compared with the prior art, the refrigerator of this application adds an easily detachable storage rack. Users can selectively suspend the storage rack on the refrigerator shelf or the inner top wall of the refrigerator compartment according to their usage, thereby improving the space utilization rate of the refrigerator compartment. Specifically, the storage rack of this application consists of an upper frame and a lower frame, with a telescopic mechanism between the upper and lower frames for easy adjustment of the storage rack's size. This allows users to flexibly adjust the volume of the storage rack according to actual usage, effectively improving its adaptability. Attached Figure Description

[0070] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0071] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0072] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0073] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0074] Common household refrigerators typically have multiple glass shelves, which users can selectively place at different heights within the refrigerator compartment according to their needs. This divides the refrigerator compartment into multiple spaces, making it convenient to place refrigerated items in each space.

[0075] In practical applications, the space occupied by refrigerated items stored in the aforementioned spaces is limited. The height or quantity of refrigerated items in each space cannot fill the entire space, resulting in a large amount of unused space above the refrigerated items and between the shelves, leading to wasted space. Specifically, for example... Figure 1 As shown, multiple shelves are installed in the refrigerator compartment, giving the compartment multiple storage spaces M. In these storage spaces, such as the space below each shelf M2 or the space below the top shelf and the interior ceiling M1, there is often unused space.

[0076] Therefore, this application provides a storage rack and a refrigerator. In view of the above-mentioned unused space inside the refrigerator, the internal components of the refrigerator are redesigned, and an easily detachable storage container that can be selectively installed in the above-mentioned unused space is considered. In this way, these unused spaces are used to store refrigerated items, effectively solving the problem of low space utilization in the refrigerator compartment of traditional refrigerators. The following is a detailed description of the invention.

[0077] Please refer to the following: Figure 2 , Figure 3 and Figure 4 The refrigerator includes a cabinet 100, a shelf 200, and a storage rack 300 as described in this application.

[0078] like Figure 2 As shown, the cabinet 100 is constructed with a compartment 101 having an access port. Multiple removable shelves 200 are provided in the compartment 101 of the cabinet 100. These shelves 200 can preferably be made of glass and can be selectively set at different heights of the compartment 101 by the user, thereby dividing the refrigerator compartment 101 into multiple storage spaces, making it convenient for the user to classify and store refrigerated items.

[0079] The storage rack 300 can preferably be made of metal, such as stainless steel, or preferably molded from plastic. The storage rack 300 can be selectively installed by the user between adjacent shelves 200, or between the inner top wall of the refrigerator compartment 101 and the top shelf 200, depending on the actual usage.

[0080] like Figure 3 and Figure 4 As shown, the storage rack 300 includes an upper frame 1 and a lower frame 2. The upper frame 1 is provided with multiple suction cups 3 for fixing to the shelf 200 or the inner top wall of the compartment 101. These suction cups 3 can preferably be vacuum suction cups. Utilizing the adsorption properties of their output surfaces, the suction cups 3 can adhere to the glass shelf 200 or the inner top wall of the metal compartment 101. In this way, the storage rack 300 is suspended from the bottom of the shelf 200 or the inner top wall of the refrigerator compartment 101.

[0081] Regarding the specific structure of the storage shelf 300, such as Figure 3 and Figure 4 As shown, the upper frame 1 and the lower frame 2 form a frame with at least one side opening. A telescopic mechanism 400 is provided between the upper frame 1 and the lower frame 2, allowing the lower frame 2 to extend and retract on the upper frame 1, thereby adjusting the volume of the frame. This allows users to adjust the size of the storage shelf 300 according to actual usage, thus improving its adaptability.

[0082] Compared with the prior art, the refrigerator provided in this application embodiment adds an easily detachable storage shelf 300. Users can selectively hang the storage shelf 300 on the refrigerator shelf 200 or on the inner top wall of the refrigerator compartment 101 according to their usage, thereby improving the space utilization of the refrigerator compartment 101.

[0083] In this embodiment, the storage rack 300 consists of an upper frame 1 and a lower frame 2, and has a frame structure with an opening on at least one side, allowing users to place refrigerated items into the storage rack 300 through the side opening without disassembling it. A telescopic mechanism 400 is also provided between the upper frame 1 and the lower frame 2, allowing the lower frame 2 to extend or retract relative to the upper frame 1, thereby adjusting the overall size of the frame. Thus, users can flexibly adjust the size of the storage rack 300 according to the available space volume in the corresponding location within the refrigerator compartment 101, effectively improving usability.

[0084] To accommodate the internal structure of the refrigerator compartment 101, the storage shelf 300 preferably adopts a rectangular frame structure, giving it a rectangular shape with four corners. Regarding the telescopic mechanism 400 on the storage shelf 300, please refer to one embodiment of this application. Figure 3 and Figure 4 The telescopic mechanism 400 includes hollow columns 4 set on the upper frame 1 and support columns 5 set on the lower frame 2. The hollow columns 4 are located at the four corners of the upper frame 1, and the support columns 5 are located at the four corners of the lower frame 2. Each support column 5 is inserted into each hollow column 4, and each support column 5 can move synchronously on each hollow column 4.

[0085] In this way, the lower frame 2 can move synchronously in the hollow columns 4 of the upper frame 1 with each support column 5, so that the lower frame 2 can retract or expand on the upper frame 1, thereby adjusting the volume of the storage rack 300.

[0086] Based on the above, please refer to the following: Figure 4 and Figure 5The hollow column 4 is provided with multiple adjustment holes 41, which are arranged in an orderly manner along the length of the hollow column 4. The support column 5 is provided with elastic buckles 51 for selectively engaging with the adjustment holes 41.

[0087] In this embodiment, when the storage rack 300 is fixed to the bottom of the shelf 200 by the suction cup 3, the hollow columns 4 of the upper frame 1 are all vertically arranged, and the hollow columns 4 have multiple adjustment holes 41 of different heights. The support column 5, which is sleeved in the hollow column 4, can move in the hollow column 4 and selectively fasten to the corresponding adjustment hole 41 using elastic buckles 51, thereby adjusting the extension and retraction range of the lower frame 2 to the upper frame 1, and realizing the stepped adjustment of the volume of the storage rack 300.

[0088] Please refer to the following: Figure 5 , Figure 6 and Figure 7 The elastic buckle 51 includes a button 511 and an elastic element 512 connected together. The elastic element 512 can preferably be a spring and is disposed inside the support column 5. A through hole (not shown in the figure) is provided on the support column 5, and the elastic element 512 is positioned corresponding to the through hole. The elastic element 512 has a force that pushes the button 511 toward the through hole. Under the force of the elastic element 512, the button 511 passes through the through hole and extends beyond the hollow column 4 through the adjustment hole 41 corresponding to the position.

[0089] In actual operation, a person presses button 511 to compress elastic element 512, causing button 511 to move from adjustment hole 41 on hollow column 4 into hollow column 4, thereby releasing the engagement with adjustment hole 41. Then, the lower frame 2 can be pushed into the upper frame 1 or pulled outward to adjust the size of storage rack 300. During this process, button 511 moves with support column 5 in the hollow column 4 of upper frame 1 and slides into another adjacent adjustment hole 41, thus automatically engaging with the adjacent adjustment hole 41.

[0090] In this way, the user can release the current fixed position by pressing button 511, and then operate the lower frame 2 to move on the upper frame 1. By using the engagement of button 511 and adjustment hole 41, the lower frame 2 can be automatically fixed in different fixed positions, thereby locking the size of the adjusted storage rack 300.

[0091] It should be noted that the above-mentioned adjustment operation of the storage rack 300 can be performed before the shelf 200 is installed in the refrigerator compartment 101. First, fix the storage rack 300 on the shelf 200, then adjust the size of the storage rack 300, and then install the shelf 200 together with the storage rack 300 in the refrigerator compartment 101.

[0092] Alternatively, the shelf 200 can be fixed inside the refrigerator compartment 101 first, then the size of the storage rack 300 can be adjusted, and then the storage rack 300 can be installed on the shelf 200.

[0093] Alternatively, after both the shelf 200 and the storage rack 300 are installed in the refrigerator compartment 101, the size of the storage rack 300 can be adjusted directly when it is not in use.

[0094] Therefore, users can make adjustments based on their usage or operating habits; no specific limitations are set here.

[0095] Regarding the structure of the upper frame 1, please refer to one embodiment of this application. Figure 8 The upper frame 1 includes a first back rail 11 and two first side rails 12 on both sides. The two ends of the first back rail 11 and the two ends of each of the first side rails 12 are respectively connected to the adjacent hollow columns 4. It can be seen that the structure of the entire upper frame 1 is simple and effectively ensures the structural strength of the entire upper frame 1.

[0096] Each hollow column 4 has a suction cup 3 at its top, allowing the four suction cups 3 to be simultaneously attached to the mounting carrier, such as the shelf 200 or the inner top wall of the compartment 101, effectively ensuring the installation stability of the storage rack 300.

[0097] Preferably, in this embodiment, such as Figure 8 As shown, both the first back panel 11 and the first side panel 12 preferably include multiple connecting plates, with adjacent connecting plates spaced apart, and both ends of each connecting plate are fixedly connected to the hollow column 4. This serves both to provide a surrounding barrier, preventing refrigerated items from falling from the side of the storage rack 300, and to allow airflow through the gaps between the connecting plates, enabling frozen air to enter the storage rack 300 and ensuring the refrigeration effect of the refrigerated items.

[0098] For the structure of the lower frame 2, please refer to one embodiment of this application. Figure 8 and Figure 9 The lower frame 2 includes a second back rail 21, second side rails 22 on both sides, and a base plate 23. The four corners of the base plate 23 are connected to the support columns 5 respectively.

[0099] In this embodiment, the specific structure of the second back rail 21 and the second side rails 22 on both sides is preferably the structure described above, which is composed of multiple connecting plates with a spacing of 10 ...

[0100] The second back panel 21 is offset from the first back panel 11 on the upper frame 1, and the second side panels 22 on both sides are offset from the first side panels 12 on both sides of the upper frame 1. This can be understood as follows: Figure 8As shown, as an example, the downward vertical line H1 of the second side rail 22 on the lower frame 2 does not overlap with the downward vertical line H2 of the first side rail 12 on the upper frame 1. In this way, the second side rail 22 and the first side rail 12 can avoid each other, so that the entire lower frame 2 can move in and out of the upper frame 1.

[0101] In practical applications, the four support columns 5 on the lower frame 2 are respectively connected to the four hollow columns 4 on the upper frame 1, and they need to move synchronously to adjust the size of the entire storage rack 300. However, there is a second back rail 21 or a second side rail 22 between adjacent support columns 5. The ends of the second back rail 21 and the second side rail 22 are easily blocked by the hollow columns 4, which makes it difficult for the upper frame 1 and the lower frame 2 to retract relative to each other, making it difficult to carry out the adjustment operation.

[0102] Therefore, the specific structure of the second back rail 21 and the second side rail 22 on the lower frame 2 is further optimized. In one embodiment of this application, both the second back rail 21 and the second side rail 22 are vertically connected to the base plate 23, and the lengths of the second back rail 21 and the second side rail 22 are respectively less than the distance between two adjacent hollow columns 4 on the upper frame 1. This can be understood as follows: Figure 9 As shown, as an example, the length L1 of the second side rail 22 of the lower frame 2 is less than the distance L2 between the two hollow columns 4 located on the side of the upper frame 1.

[0103] In this way, when the lower frame 2 retracts into the upper frame 1, the two ends of the second back rail 21 and the second side rail 22 can avoid each other from the position of the hollow column 4 of the upper frame 1, effectively ensuring the operability of the storage shelf size adjustment.

[0104] For the specific structure of the second back panel 21 and the second side panel 22 on the lower frame 2, please refer to another embodiment of this application. Figure 6 and Figure 10 The two ends of the second back rail 21 and the two ends of the second side rail 22 are respectively connected to the adjacent support columns 5. Each hollow column 4 of the upper frame 1 is provided with a sliding groove 42 for the second back rail 21 or the second side rail 22 to slide into.

[0105] Thus, the second back rail 21 and the second side rail 22, which are connected to the support column 5, can both cooperate with the sliding grooves 42 of each hollow column 4 of the upper frame 1. This ensures the operability of adjusting the size of the storage rack 300, and also utilizes the sliding grooves 42 on the hollow column 4 to provide guidance, thereby improving the accuracy of the adjustment operation.

[0106] In this embodiment, a structure combining the above two methods is preferred. Specifically, as shown below... Figure 9As shown, the second side rails 22 on both sides of the lower frame 2 are integrally connected to the base plate 23 and stand upright on the two side edges of the base plate 23. The length L1 of the second side rails 22 on both sides is less than the distance L2 between two adjacent hollow columns 4 at the corresponding positions of the upper frame 1, so that when the lower frame 2 is retracted into the upper frame 1, the ends of the second side rails 22 can avoid the position of the hollow columns 4. In addition, as Figure 10 As shown, both ends of the second back rail 21 of the lower frame 2 are fixedly connected to the support column 5. The hollow column 4 of the upper frame 1 has a corresponding sliding groove 42, and the sliding groove 42 has a slot at the lower end of the hollow column 4, so that when the lower frame 2 is stored in the upper frame 1, it can be inserted into the sliding groove 42 through the slot and move along the sliding groove 42, effectively ensuring the smoothness of the adjustment operation.

[0107] In practical applications, since the storage rack 300 provided in this embodiment of the application is attached to the shelf 200 by suction cups 3, and thus the storage rack 300 can be suspended from the bottom of the shelf 200, the fixing strength of the suction cups 3 is particularly important. In this application scenario, the suction cups 3 are generally vacuum suction cups 3. Vacuum suction cups 3 are vacuum adsorption components that maintain the adhesion between two objects through vacuum. Therefore, due to factors such as installation operation, usage environment, and the load-bearing capacity of the storage rack 300, relying solely on the adsorption of the suction cups 3 to achieve fixation to the shelf 200 carries the risk of loosening.

[0108] Therefore, the structure of the suction cup 3 is further improved. Please refer to one embodiment of this application. Figure 11 and Figure 12 The suction cup 3 also includes a hook 31, which is mounted on the suction cup via a pivot, allowing the hook to be flipped outward to fasten onto the shelf.

[0109] In this embodiment, the suction cup 3 is provided with a rotating seat 32 for setting the hook 31. The rotating seat 32 is provided with a rotating shaft 321. The hook 31 is connected to the rotating shaft 321 on the rotating seat 32 and can rotate on the suction cup 3, so that the hook 31 can be flipped outward and fastened to the edge of the shelf 200.

[0110] Therefore, a movable hook 31 is added to the suction cup 3. When the storage rack 300 is fixed to the shelf 200 by the suction cup 3, the hook 31 is simultaneously used to fasten and fix it to the edge of the shelf 200, thereby increasing the auxiliary fixing structure, realizing double fixing protection, and effectively improving the fixing effect of the storage rack 300.

[0111] Furthermore, since the shelf 200 is generally made of flat glass, its surface is smooth, which affects the fastening stability of the hook 31. Therefore, in one embodiment of this application, please refer to... Figure 13 and Figure 14The edge of the shelf 200 is provided with an edge band 6, the shape of which matches the hook 31 so that the hook 31 can be fastened to the edge band 6.

[0112] In this embodiment, as Figure 13 As shown, the edging 6 can preferably be a C-shaped strip sleeve, the length of which is similar to the length of the shelf 200, and is fitted onto the edge of the shelf 200. The shape of the edging 6 matches the shape of the hook 31 so that when the hook 31 is fastened onto the shelf 200, the hook 31 can be fastened onto the edging 6, effectively improving the fixing effect of the hook 31 on the shelf 200.

[0113] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
