[0010] In one of the embodiments, the first limiting unit further includes an elastic abutment, the elastic abutment is limited in the first limiting bracket, and the elastic abutment is used to apply a force on the positioning slide toward the second limiting unit.

[0011] In one embodiment, the first limiting unit further includes a positioning shaft extending along the first direction, one end of the positioning shaft is limited to the first limiting bracket, and the other end of the positioning shaft is telescopically connected to the positioning slider.

[0012] In one embodiment, the elastic supporting member is sleeved outside the positioning shaft, and two ends of the elastic supporting member are respectively supported by the first limiting bracket and the positioning slider.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a refrigerator 100 for refrigerating or freezing food or other items. The refrigerator 100 includes a box body 10 and an inner liner structure accommodated in the box body 10. The inner liner structure includes an inner liner body 20 having a receiving cavity 21 for food. The receiving cavity 21 has an open end and a closed end arranged opposite to each other in a first direction. A user can take food in and out through the open end.

[0036] Furthermore, in order to achieve the layered placement of food to increase the storage capacity of the accommodating cavity 21, the refrigerator 100 further includes at least one shelf 50 for placing food, and the inner tank structure further includes at least one set of shelf limiting components for installing the shelf 50. Specifically, a set of shelf limiting components includes two fixed ribs 40, and the two fixed ribs 40 are spaced apart and arranged on both sides of the cavity wall of the accommodating cavity 21 in a second direction perpendicular to the first direction, and each fixed rib 40 extends from an open end to a closed end along the first direction, and the opposite side edges of the shelf 50 in the second direction can be respectively limited on the two fixed ribs 40 of the same shelf limiting component.

[0037] Preferably, a plurality of groups of shelf limiting components are provided in the inner tank body 20, and the plurality of groups of shelf limiting components are arranged at intervals in a third direction which is perpendicular to both the first direction and the second direction. The refrigerator 100 also includes a plurality of shelves 50, and each shelf 50 is limited on a group of shelf limiting components.

[0038] In the present application, the first direction is the front-to-back direction of the refrigerator 100 (i.e. Figure 1 The second direction is the left-right direction of the refrigerator 100 (i.e. Figure 1 The third direction is the height direction of the refrigerator 100 (i.e. Figure 1 The front end of the shelf 50 refers to an end of the shelf 50 close to the closed end of the accommodating cavity 21, and the rear end of the shelf 50 refers to an end of the shelf 50 close to the open end of the accommodating cavity 21.

[0039] As described in the background technology, one end of the existing fixed rib is provided with a limiting groove, and one end of the shelf is formed with a limiting protrusion protruding downward, and the limiting protrusion is limited in the limiting groove, so that the movement of the shelf in the first direction can be limited. However, with the above-mentioned assembly method, a space for the limiting protrusion to move along the first direction needs to be reserved on the fixed rib to avoid interfering with the assembly of the shelf, and the setting of the moving space causes the gap of the slot for the shelf to be inserted in the third direction to be too large, so that the shelf after assembly has a large gap in the first direction, which is easy to cause the shelf to warp or shake during use, and even cause the food on the shelf to fall off, which is inconvenient for users to use.

[0040] Moreover, as large-volume refrigerators become more popular, the weight of refrigerators increases, and the resulting transportation problems are increasing. In order to prevent the shelves from being damaged during the violent handling and transportation of the refrigerator, it is usually necessary to add additional protective parts to the shelves, such as adding buffer foam to the front and back ends of the shelves, or using buffer foam for protection while fixing the left and right sides of the shelves with tape, which significantly increases unnecessary material costs and labor costs, and makes the packaging process more complicated and cumbersome, reducing packaging efficiency.

[0041] like Figure 3 and Figure 4 As shown, in order to solve the above-mentioned problem, two fixed ribs in the same group of fixed ribs 40 are symmetrically arranged, and each fixed rib 40 is constructed to form a limiting gap extending from the open end of the accommodating cavity to the closed end along the first direction. The length of the limiting gap in the first direction can be changed under the action of external force, and the shelves 50 installed in a group of shelf limiting assemblies are limited in the two side edges in the second direction respectively.

[0042] In this way, when installing the shelf 50, the shelf 50 can be inserted into the limiting gap by increasing the length of the limiting gap in the first direction. After the shelf 50 is inserted into the limiting gap, the length of the limiting gap in the first direction can be reduced until the length of the limiting gap matches the length of the shelf 50 in the first direction, thereby preventing the shelf 50 from detaching from the shelf limiting assembly.

[0043] Compared with the technical solution in the prior art that requires setting a limiting protrusion on the shelf 50, the shelf limiting assembly of the present application does not need to reserve a space for the limiting protrusion of the shelf 50 to move, thereby avoiding a large gap in the third direction of the assembled shelf 50, thereby preventing the shelf 50 from warping or shaking during use. Moreover, during the transportation of the refrigerator 100, there is no need to set up other protective parts to provide additional protection for the shelf 50, thereby reducing the packaging cost of the refrigerator 100.

[0044] like Figure 1 and Figure 2 As shown, specifically, the shelf 50 is roughly a rectangular flat plate structure. In some other embodiments, the shelf 50 may also be a fully wrapped structure, or an assembled structure with extruded strips at the front and rear ends. There is no need to set a raised limiting structure on the shelf 50 to mate with the fixed component.

[0045] Each fixed rib 40 includes a rib body 41, a first limiting unit 43, and a second limiting unit 45. The rib body 41 is integrally formed on the cavity wall of the accommodating cavity 21 and extends from the open end to the closed end of the accommodating cavity 21 along the first direction. The cross section of the rib body 41 perpendicular to the first direction is substantially rectangular. The first limiting unit 43 and the second limiting unit 45 are spaced apart at opposite ends of the rib body 41 in the first direction, and a limiting gap for limiting the shelf 50 is defined between the first limiting unit 43 and the second limiting unit 45.

[0046] See also Figure 5 and Figure 6 The first limiting unit 43 includes a first limiting bracket 432, a positioning slider 434, a positioning shaft 436 and an elastic supporting member 438. The positioning slider 434, the positioning shaft 436 and the elastic supporting member 438 are all assembled in the first limiting bracket 432 to realize the length adjustment of the limiting gap.

[0047] Specifically, the first limiting bracket 432 is a hollow shell structure, having a bottom wall and a side wall extending from the edge of the bottom wall in the same direction, and the side wall surrounds the bottom wall along the circumferential direction to form a limiting space with one end open. When the first limiting bracket 432 is installed on the fixing rib 40, the side of the side wall of the first limiting bracket 432 away from the bottom wall is in contact with the cavity wall of the accommodating cavity 21.

[0048] Furthermore, the first limiting bracket 432 includes a first limiting portion 4321, a second limiting portion 4323 and a third limiting portion 4325 which are arranged in sequence in the third direction, and the side walls of the first limiting portion 4321, the second limiting portion 4323 and the third limiting portion 4325 on one side in the first direction are flush, and the length of the first limiting portion 4321 in the first direction is greater than the length of the second limiting portion 4323 in the first direction and is less than the length of the third limiting portion 4325 in the second direction.

[0049] A first limiting groove 4327 is defined between the first limiting portion 4321 and the third limiting portion 4325 and faces the second limiting unit 45. A connecting hole 4323a is provided on one side wall of the second limiting portion 4323 in the first direction, which is connected to the first limiting groove 4327, and the connecting hole 4323a is connected to the end face of the side wall away from the bottom wall. A positioning shaft limiting groove 4323b is provided on the other side wall of the second limiting portion 4323 in the first direction, and the positioning shaft limiting groove 4323b is arranged opposite to the connecting hole 4323a in the first direction, and the positioning shaft limiting groove 4323b is connected to the end face of the side wall away from the bottom wall.

[0050] The third limiting portion 4325 is provided with a limiting slot 4325a for matching with the rib body 41, the limiting slot 4325a extends along the first direction and passes through a side wall of the third limiting portion 4325 close to the second limiting unit 45. The third limiting portion 4325 is further provided with a threaded mounting hole 4325e on a side away from the second limiting unit 45, the central axis direction of the threaded mounting hole 4325e extends along the second direction, and the first limiting bracket 432 is fixedly connected to the inner container body 20 through the threaded mounting hole 4325e.

[0051] As a preferred embodiment, the third limiting portion 4325 forms a side wall of the first limiting groove 4327, which has a first limiting surface 4325b, a second limiting surface 4325c and a third limiting surface 4325d which are sequentially connected along the first direction, and the first limiting surface 4325b is located on the side of the second limiting surface 4325c close to the second limiting unit 45. In this way, the shelf 50 can enter the first limiting groove 4327 along the first limiting surface 4325b, the second limiting surface 4325c and the third limiting surface 4325d. The second limiting surface 4325c forms a side groove wall of the first limiting groove 4327, and the second limiting surface 4325c extends obliquely from the side connected to the first limiting surface 4325b to the side connected to the third limiting surface 4325d in a direction away from the first limiting portion 4321, thereby avoiding interference with the shelf 50 inserted into the first limiting groove 4327 and affecting the movement of the shelf 50.

[0052] The positioning slider 434 includes a slider body 4341, a slider abutment 4343, and a slider connection 4345. The slider body 4341 is a cubic structure, the slider abutment 4343 is connected to one end of the slider body 4341, and the outer diameter of the slider abutment 4343 is greater than the outer diameter of the slider body 4341. The slider connection 4345 is connected to one end of the slider abutment 4343 away from the slider body 4341, and the slider connection 4345 is a cylindrical structure with a central axis extending along the first direction, and a slider connection hole extending along the axial direction is provided at the center of the slider connection 4345.

[0053] In this way, the slider body 4341 of the positioning slider 434 can pass through the connecting hole 4323a of the second limiting portion 4323 of the first limiting bracket 432 and extend into the first limiting groove 4327, the slider connecting portion 4345 is accommodated in the second limiting portion 4323, and the slider supporting portion 4343 is accommodated in the second limiting portion 4323, and can be supported on the side wall of the second limiting portion 4323 facing the first limiting groove 4327 with 4323a.

[0054] like Figure 7 As shown in the figure, as a preferred embodiment, the outer surface of the positioning slider 434 is provided with a plurality of sliding parts 4347, each of which is in the shape of a long strip extending along the first direction, and the cross section of the sliding part 4347 perpendicular to the first direction is semicircular. In this way, the positioning slider 434 contacts the first limiting bracket 432 through the sliding part 4347, thereby reducing the friction between the two.

[0055] Please continue reading Figure 5 and Figure 6The positioning shaft 436 includes a positioning shaft body 4361 and a positioning shaft stopper 4363. The positioning shaft body 4361 is cylindrical and extends in the first direction, and the diameter of the positioning shaft body 4361 is smaller than the diameter of the slider connection hole provided on the slider connection part 4345. The positioning shaft stopper 4363 is connected to one end of the positioning shaft body 4361 in the axial direction, the outer diameter of the positioning shaft stopper 4363 is larger than the outer diameter of the positioning shaft body 4361, and the shape of the positioning shaft stopper 4363 matches the positioning shaft stopper groove 4323b of the second stopper 4323.

[0056] In this way, the positioning shaft limiting portion 4363 is limited in the positioning shaft limiting groove 4323b of the second limiting portion 4323, and the end of the positioning shaft 436 away from the positioning shaft limiting portion 4363 is inserted into the slider connecting portion 4345 of the positioning slider 434, and can reciprocate and extend relative to the slider connecting portion 4345.

[0057] The elastic abutment 438 is formed by a spring, and is sleeved outside the positioning shaft 436. The two ends of the elastic abutment 438 respectively abut against the first limiting bracket 432 and the slider abutment 4343 of the positioning slider 434. The elastic abutment 438 can be used to apply a force to the slider abutment 4343, so that the positioning slider 434 has a tendency to move toward the second limiting unit 45.

[0058] In this way, the positioning slider 434 can reciprocate in the first direction under the action of external force to change the length of the limiting gap in the first direction, thereby matching the length of the shelf 50 in the first direction to clamp the shelf 50.

[0059] The second limiting unit 45 is formed integrally with the rib body 41, and the second limiting unit 45 is bent and extended from one end of the rib body 41 toward the direction where the second limiting unit 45 is located, thereby forming a second limiting groove arranged opposite to the first limiting groove 4327. The height of the second limiting groove in the third direction is set according to the thickness of the shelf 50.

[0060] The first limiting unit 43 is assembled as follows:

[0061] First, the elastic resisting member 438 is sleeved on the slider connecting portion 4345 of the positioning slider 434 , and at the same time, the positioning shaft body 4361 of the positioning shaft 436 passes through the elastic resisting member 438 and is inserted into the slider connecting portion 4345 of the positioning slider 434 .

[0062] Then, the positioning slider 434 and the positioning shaft 436 are pressed axially and the elastic supporting member 438 is compressed. Then, the above-mentioned components are slid as a whole into the second limiting portion 4323 of the first limiting bracket 432, and the positioning shaft limiting portion 4363 is accommodated in the positioning shaft limiting groove 4323b, and the slider body 4341 extends from the connecting hole 4323a of the second limiting portion 4323 into the first limiting groove 4327.

[0063] Finally, the assembled first limiting unit 43 is inserted into the fixed rib 40 from front to back along the first direction, and the limiting slot 4325a of the first limiting bracket 432 is plugged into the fixed rib 40. Then, fasteners such as screws are passed through the threaded mounting hole 4325e to fix the first limiting bracket 432 on the cavity wall of the inner tank body 20.

[0064] The above-mentioned shelf 50 is installed as follows:

[0065] First, insert the front end of the shelf 50 into the first limiting groove 4327 of the first limiting unit 43 of the two fixed ribs 40 of the same fixed assembly, and the rear end of the shelf 50 is freely placed on the second limiting unit 45 of the fixed rib 40. At this time, the rear end of the shelf 50 does not enter the second limiting groove.

[0066] Then, the front end of the shelf 50 is moved along the first direction away from the second limiting unit 45, and the shelf 50 is supported on the positioning slider 434 of the first limiting unit 43. The positioning slider 434 contracts inwardly under the pressure of the shelf 50, and the shelf 50 moves forward until the rear end of the shelf 50 leaves the second limiting unit 45 and falls onto the rib body 41. The two side edges of the shelf 50 are both clamped in the limiting gap, and the entire shelf 50 is in a horizontal state.

[0067] Finally, the shelf 50 is released, and the elastic abutment member 438 abuts the positioning slider 434 to slide in the direction of the second limiting unit 45, thereby pushing the positioning slider 434 to move backward and enter the second limiting groove of the second limiting unit 45. In this way, the front and rear ends of the shelf 50 are respectively limited in the first limiting groove 4327 and the second limiting groove.

[0068] The above-mentioned shelf 50 is disassembled as follows:

[0069] First, the shelf 50 is moved forward, and the shelf 50 pushes the positioning slider 434 to overcome the force of the elastic resisting member 438 and retract inward until the rear end of the shelf 50 is separated from the second limiting groove of the second limiting unit 45. Then, the rear end of the shelf 50 is lifted up to make the rear end of the shelf 50 leave the rib body 41, and finally, the forward pulling force applied to the shelf 50 is released, and the positioning slider 434 in the first limiting unit 43 is pushed by the elastic resisting member 438 to extend into the first limiting groove 4327, and finally the shelf 50 is pushed out along the first direction.

[0070] The above-mentioned inner tank structure and refrigerator 100 can firmly limit the shelf 50 in the inner tank structure through the arrangement of the first limiting unit 43 and the second limiting unit 45, thereby solving the problem that the shelf 50 is easy to warp and shake, improving the user experience and safety performance, and no additional protective materials for the shelf 50 are required during transportation, thereby minimizing the additional cost of the product and greatly improving production efficiency. In addition, the shelf 50 installed in the fixed component can be designed as a flat plate in a very simple manner without adding a limiting structure. By adjusting the spacing of the first limiting groove 4327 and the spacing of the second limiting groove, the installation of shelves 50 of different thicknesses and types can be achieved.

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
