[0053] Figure 1 A three-dimensional structural diagram of the storage rack provided in an embodiment of the present invention is illustrated. Figure 2 An exploded structural diagram of the shelf provided in an embodiment of the present invention is illustrated; as follows: Figure 1 and Figure 2 As shown, the storage rack includes a base 10, a first locking component 20, and a second locking component 50. The first locking component 20 is connected to the base 10 and is adapted to switch between an extended state and a retracted state. The second locking component 50 is connected to the first locking component 20. In the extended state, the second locking component 50 locks the first locking component 20, and the base 10 is adapted to be locked to the storage cabinet by the first locking component 20. In the retracted state, the second locking component 50 releases the lock on the first locking component 20, and the first locking component 20 releases the lock on the base 10.

[0054] According to an embodiment of the present invention, by retracting the first locking component 20, the first locking component 20 can be released from locking the base, allowing the position of the shelf to be adjusted as needed, thus enhancing the user experience. By extending the first locking component 20, the base can be locked to the storage cabinet via the first locking component 20, and the first locking component 50 can lock the first locking component 20, achieving a secondary locking function and preventing the shelf from sliding down due to the weight of the items. The shelf of the present invention has the advantages of good stability, simple structure, low production cost, convenient installation and disassembly, and easy operation.

[0055] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the second locking component 50 includes a locking handle 51, which is connected to the first locking component 20. A first positioning part 53 is provided at the bottom of the base 10. In the extended state, the locking handle 51 is adapted to connect with the first positioning part 53. Because the locking handle 51 is connected to the first positioning part 53, the first locking component 20 is locked by the second locking component 50, preventing the first locking component 20 from moving. Therefore, the shelf cannot move, effectively preventing the shelf from sliding down due to the weight of the items. In the retracted state, the locking handle 51 separates from the first positioning part 53. At this time, the second locking component 50 releases its lock on the first locking component 20. Furthermore, by releasing the first locking component 20 from locking the base 10, the installation position of the shelf can be adjusted as needed.

[0056] In an embodiment of the present invention, the second locking component 50 further includes a first elastic member 52. A first side of the locking handle 51 is rotatably connected to the first locking component 20. A second side of the locking handle 51 is provided with a locking portion 54 adapted to engage with the first positioning portion 53. A first end of the first elastic member 52 is connected to the first locking component 20, and a second end of the first elastic member 52 is connected to the locking handle 51. Compared to other connection methods, the engagement of the first positioning portion 53 and the locking portion 54 facilitates the separation of the locking portion 54 from the first positioning portion 53, making operation simpler.

[0057] In an embodiment of the present invention, the first positioning part 53 is a protruding ridge, and the locking part 54 is a locking tongue. In the extended state, the locking tongue locks the protruding ridge. When it is necessary to separate the locking tongue from the protruding ridge, simply rotate the locking handle 51 away from the protruding ridge by a predetermined angle to achieve separation. Of course, the specific structure of the first positioning part 53 and the locking part 54 is not limited to this; the first positioning part 53 can also be a positioning groove, and the locking part 54 can also be a positioning post 26.

[0058] In an embodiment of the present invention, Figure 3A schematic diagram illustrating the connection relationship between the handle 21, the connector 23, and the lug 24 provided in an embodiment of the present invention is shown, as follows: Figure 2 and Figure 3 As shown, the first locking assembly 20 includes a handle 21, a second elastic element 22, a connector 23, and a hook 24. The handle 21 is used by the user for gripping. A first guide component is provided at the bottom of the base 10, and the handle 21 slides in cooperation with the first guide component. The second elastic element 22 provides elastic force to the handle 21, allowing the handle 21 to automatically return from a second position to a first position. Here, the first position is the position of the second elastic element 22 when it is not subjected to external force, and the second position is the position when the handle 21 drives the hook 24 to retract into the receiving cavity 11. The first end of the second elastic element 22 is connected to the base 10, and the second end of the second elastic element 22 is connected to the handle 21.

[0059] The first end of the connector 23 is connected to the handle 21. There are two connectors 23, which are used to connect the handle 21 and the hanging ear 24. The connector 23 and the handle 21 are integrally formed, which simplifies the structure of the shelf, reduces the number of parts, and lowers production costs. Both the connector 23 and the handle 21 are made of soft materials such as PP or PE. The base 10 is provided with a receiving cavity 11, and there are also two receiving cavities 11. The two receiving cavities 11 are respectively provided at both ends of the bottom of the base 10, and the receiving cavity 11 is provided with a first opening suitable for the hanging ear 24 to pass through.

[0060] There are two hanging ears 24, each disposed within a corresponding receiving cavity 11. Each hanging ear 24 is connected to the second end of a corresponding connector 23. In the extended state, the hanging ear 24 extends from the receiving cavity 11 and is adapted to connect with the storage cabinet. At this time, the handle 21 is in the first position, and the base 10 is locked to the storage cabinet via the hanging ear 24. The second locking component 50 locks the first locking component 20. In the retracted state, the hanging ear 24 is adapted to separate from the storage cabinet and retracts into the receiving cavity 11. The second locking component 50 releases the lock on the first locking component 20. At this time, the handle 21 is in the second position, and the hanging ear 24 is released from locking the base 10.

[0061] When the height of the shelf needs to be adjusted, the second locking component 50 releases the lock on the first locking component 20. Then, by retracting the first locking component 20, it releases the lock on the base. Users can adjust the shelf position according to the height of the items to be placed, enhancing the user experience and improving refrigerator space utilization. After the shelf position is adjusted, extending the first locking component 20 locks it to the cabinet. The second locking component 50 then locks the first locking component 20, achieving a secondary locking function to prevent the shelf from sliding down due to the weight of the items. It should be noted that the connector 23 needs a certain degree of elasticity to allow for deformation during movement with the handle 21. Furthermore, the connector 23 needs a certain degree of rigidity to push the hanging ear 24 out of the receiving cavity 11 as the handle 21 returns from the second position to the first position. The connector 23 can be a connecting piece, a steel wire, or a steel sheet.

[0062] In embodiments of the present invention, the second elastic element 22 can be in at least the following forms, which are described below:

[0063] Format 1:

[0064] like Figure 2 and Figure 3 As shown, the second elastic element 22 is a second compression spring. To facilitate the installation of the second compression spring, a boss 28 is provided at the bottom of the base 10, and the boss 28 has a spring insertion hole. A spring positioning post 27 corresponding to the spring insertion hole is provided on the upper part of the handle 21. One end of the second compression spring is inserted into the spring insertion hole, and the other end is sleeved on the spring positioning post 27. When the handle 21 is pulled by hand, the second compression spring is compressed, and the handle 21 drives the hanging ear 24 to retract into the receiving cavity 11 through the connecting member 23. When the handle 21 is released, the second compression spring pushes the handle 21 to the first position, and the handle 21 drives the hanging ear 24 to extend out of the receiving cavity 11 through the connecting member 23. The boss 28 has two functions: first, it can restrain the second elastic element 22; second, it can limit the position of the handle 21.

[0065] Form Two:

[0066] The second elastic element 22 is a tension spring. One end of the tension spring is inserted into or hooked onto the boss 28, and the other end is hooked onto the spring positioning post 27. When the handle 21 is pulled by hand, the tension spring is stretched, and the handle 21 drives the hanging ear 24 to retract into the receiving cavity 11 through the connector 23. When the handle 21 is released, the tension spring drives the handle 21 to move to the first position, and the handle 21 drives the hanging ear 24 to extend out of the receiving cavity 11 through the connector 23.

[0067] Form 3:

[0068] The second elastic element 22 is a V-shaped spring. The first end of the V-shaped spring is engaged with the boss 28, and the other end is engaged with the spring positioning post 27. The working method of the V-shaped spring is the same as that of the second compression spring.

[0069] In an embodiment of the present invention, a first guide component is provided at the bottom of the base 10, and the first guide component is connected to the handle 21 via a sliding connection structure. The sliding connection between the first guide component and the handle 21 allows the handle 21 to move along a predetermined trajectory and ensures smoother movement.

[0070] In an embodiment of the present invention, the first guide component includes a first guide groove 12 disposed at the bottom of the base 10. The first guide groove 12 is located between two receiving cavities 11. The width of the first guide groove 12 is adapted to the width of the handle 21. The boss 28 is located within the first guide groove 12. The handle 21 is disposed within the first guide groove 12 and can slide along the first guide groove 12.

[0071] A sliding connection structure includes a sliding groove and a positioning protrusion. The positioning protrusion engages with the sliding groove and slides in cooperation with it. Sliding connection structures can be at least the following types; the following describes several forms of sliding connection structures:

[0072] Formation Method 1:

[0073] The slide groove is formed on the groove wall of the first guide groove 12, and the positions of the slide grooves on the two groove walls correspond. The positioning protrusion is formed on the side of the handle 21, and the positions of the positioning protrusions on the two sides correspond. The positioning protrusion can be slidably inserted into the slide groove.

[0074] Formation Method Two:

[0075] The sliding groove is formed on the side of the handle 21, and the positions of the sliding grooves on the two sides correspond. The positioning protrusion is formed on the groove wall of the first guide groove 12, and the positions of the positioning protrusions on the two groove walls correspond. The positioning protrusion can be slidably inserted into the sliding groove.

[0076] In one embodiment of the present invention, the first guide component includes a first guide groove 12 disposed at the bottom of the base 10, and a positioning protrusion disposed on the upper surface of the handle 21. The upper surface of the handle 21 is fitted with the lower surface of the base 10, and the positioning protrusion is slidably engaged in the first guide groove 12. A boss 28 is disposed at the bottom of the base 10, and a spring insertion hole corresponding to the boss 28 is disposed at one end of the handle 21. One end of the second compression spring is inserted into the spring insertion hole, and the other end is sleeved on the spring positioning post 27.

[0077] In an embodiment of the present invention, a second guide component is provided at the bottom of the base 10, and the connector 23 is slidably disposed within the second guide component. The second guide component serves two purposes: first, to guide the connector 23; and second, to prevent the connector 23 from bending as it pushes the lug 24 out of the receiving cavity 11.

[0078] In one embodiment of the present invention, the second guide component includes two second guide grooves 13. The second guide grooves 13 are disposed at the bottom of the base 10. The second guide groove 13 is an arc-shaped groove. The connector 23 is inserted into the second guide groove 13 and slides in cooperation with the second guide groove 13.

[0079] In one embodiment of the present invention, the second guide component includes two guide tubes, which are disposed at the bottom of the base 10. Each guide tube is an arc-shaped tube, and the connector 23 is inserted into the guide tube and slides in cooperation with it.

[0080] In an embodiment of the present invention, a cavity is formed inside the handle 21, and a locking handle 51 is disposed within the cavity. The first side of the locking handle 51 is rotatably connected to the handle 21, and the side of the handle 21 facing the base 10 has a first opening 55 for the latching part 54 to extend out. In the extended state, the latching part 54 extends out from the first opening 55 and latches with the first positioning part 53. When the second side of the handle 21 rotates away from the base 10, the latching part 54 enters the cavity from the first opening 55, thereby separating from the first positioning part 53.

[0081] In an embodiment of the present invention, Figure 5 One of the cross-sectional structural schematic diagrams of the storage rack provided in the embodiment of the present invention is illustrated. Figure 6 A second cross-sectional structural schematic diagram of the storage rack provided in an embodiment of the present invention is shown, as follows: Figure 5 and Figure 6 As shown, the handle 21 has a second opening 56 on the side opposite to the base 10. The locking handle 51 includes a first plate 57, a second plate 58, and a third plate 59 connected in sequence. The first plate 57 and the third plate 59 are parallel, and the first plate 57 is rotatably connected to the handle 21 via a pin. The second opening 56 facilitates the movement of the handle 21 and also controls the locking handle 51, thereby controlling the second locking component 50 to lock and unlock the first locking component 20.

[0082] The second opening 56 corresponds to a gap between the edge of the first plate 57 and the first plate 57. There are two forms of the gap, which will be described below:

[0083] Formation Method 1:

[0084] The inner side of the edge of the second opening 56 corresponding to the first plate 57 is a slope 60. Because the inner side of this edge is a slope 60, in the extended state, the slope 60 cannot fit against the first plate 57, thus forming a gap between the slope 60 and the first plate 57, providing room for the rotation of the locking handle 51. At the same time, the slope 60 also limits the first plate 57, restricting the maximum angle of rotation of the locking handle 51.

[0085] Formation Method Two:

[0086] The first plate 57 and the edge are installed with a predetermined gap, which also provides room for the rotation of the locking handle 51.

[0087] The first elastic element 52 is a first compression spring, which provides elastic force for the locking handle 51 to reset. The second plate 58 is perpendicular to both the first plate 57 and the third plate 59. A spring positioning post 27 is provided on the side of the second plate 58 facing the first compression spring. A boss 28 is provided on the inner wall of the cavity, and the boss 28 has a spring insertion hole. The position of the spring insertion hole corresponds to the position of the spring positioning post 27. The first end of the second compression spring is sleeved on the spring positioning post 27, and the second end is inserted into the spring insertion hole. A latch is provided on the side of the third plate 59 facing the base 10, and the length of the latch is adapted to the length of the third plate 59.

[0088] In an embodiment of the present invention, the second end of the connector 23 is detachably connected to the ear 24. The connector 23 and the ear 24 are detachably connected, which facilitates the installation and removal of the ear 24.

[0089] In an embodiment of the present invention, Figure 4 Example Figure 3 A magnified view of the local structure at point A, as shown below. Figure 4 As shown, the second end of the connector 23 is provided with a positioning groove, the edge of which is provided with a limit block 25, and a positioning post 26 is provided inside the positioning groove. The lug 24 is provided with a positioning hole. The lug 24 is inserted into the positioning groove, and the positioning post 26 is inserted into the positioning hole. The limit block 25 is provided to prevent the lug 24 from separating from the positioning groove and to improve the reliability of the assembly of the connector 23 and the lug 24.

[0090] In one embodiment of the present invention, the second end of the connector 23 is provided with a latch, and the hanging ear 24 is provided with a buckle, the latch being engaged in the buckle.
