The use of "first" and "second" in the description is merely for distinguishing technical features and does not indicate the quantity of indicated technical features or implicitly indicate the order of the indicated technical features.

[0045] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0046] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the shelf assembly includes a support 100 and a shelf 200, the shelf 200 being mounted on the support 100. See also... Figure 3 and Figure 4The shelf assembly also includes a lifting mechanism 300, which includes a fixed base 310, a transmission component 320, and a lifting rod 330. The fixed base 310 is fixedly installed, for example, on the inner wall of the refrigerator. The lifting rod 330 is screwed to the fixed base 310, and can rise or fall relative to the fixed base 310 when the lifting rod 330 rotates. The upper end of the lifting rod 330 abuts against the support member 100, thereby supporting the support member 100, and the lifting rod 330 can rotate relative to the support member 100. The lifting rod 330 can drive the support member 100 to rise or fall, which in turn drives the shelf 200 to rise or fall.

[0047] It should be noted that the outer wall of the lifting rod 330 is threaded, and the fixed seat 310 is provided with a screw hole. The lifting rod 330 is screwed into the screw hole of the fixed seat 310. As the lifting rod 330 rotates, it can rise or fall relative to the fixed seat 310. The transmission component 320 is engaged with the lifting rod 330. The transmission component 320 can drive the lifting rod 330 to rotate, thereby causing the lifting rod 330 to drive the support component 100 to rise or fall relative to the fixed seat 310.

[0048] Refer to Figure 5 The shelf assembly also includes an actuating mechanism 400, which is slidably mounted on the support member 100. By pushing or pulling the actuating mechanism 400, the user can move the transmission member 320, thereby rotating the lifting rod 330. This causes the lifting rod 330 to rise or fall relative to the fixed base 310, thus causing the support member 100 to rise or fall relative to the fixed base 310. (See also...) Figure 6 and Figure 7 The actuating mechanism 400 can clamp or release the transmission component 320. Figure 6 This is a schematic diagram of the actuating mechanism 400 releasing the transmission member 320. When the actuating mechanism 400 releases the transmission member 320, the actuating mechanism 400 slides on the support member 100 to adjust the position of the actuating mechanism 400. At this time, the movement of the actuating mechanism 400 will not cause the transmission member 320 to rotate. Figure 7 This is a schematic diagram showing the actuating mechanism 400 clamping the transmission component 320. When the actuating mechanism 400 clamps the transmission component 320, it slides on the support component 100, causing the transmission component 320 to rotate. This causes the lifting rod 330 to rotate, raising or lowering the support component 100, thereby adjusting the height of the shelf 200. Therefore, by adjusting the height of the support component 100 through reciprocating movement, the actuating mechanism 400 can achieve a larger range of height adjustment within a smaller range of movement, making the adjustment of the shelf assembly more convenient.

[0049] Refer to Figure 8 and Figure 9The actuating mechanism 400 includes a base 410 and a clamping member 420. The base 410 is slidably mounted on the support member 100. The clamping member 420 is movably mounted on the base 410, and the base 410 has a stop portion 411. The clamping member 420 can cooperate with the stop portion 411 to clamp or release the transmission member 320. Figure 5 The support member 100 is provided with a guide hole 110, and the base 410 is slidably installed in the guide hole 110 and can slide along the length direction of the guide hole 110. The two ends of the guide hole 110 are respectively set as the first limit position 111 and the second limit position 112. When the actuating mechanism 400 clamps the transmission member 320, when the user actuates the actuating mechanism 400 along the direction from the first limit position 111 to the second limit position 112, the actuating mechanism 400 drives the transmission member 320 to move, thereby driving the lifting rod 330 to rotate, so that the lifting rod 330 drives the support member 100 to rise relative to the fixed seat 310, thereby adjusting the shelf 200 to rise. If it is necessary to adjust the shelf 200 to continue to rise, the actuating mechanism 400 can be released from the transmission member 320, and then the actuating mechanism 400 can be moved towards the first limit position 111. Then the actuating mechanism 400 can be clamped by the transmission member 320 and moved towards the second limit position 112. By repeating this adjustment step, the shelf 200 can be adjusted to a suitable height.

[0050] It should be noted that, referring to Figure 11 and Figure 12 The base 410 also has a second connecting portion 416, which passes through the guide hole 110, and one end of the second connecting portion 416 is connected to the abutment portion 411. This allows the base 410 to drive the abutment portion 411 to slide along the length direction of the guide hole 110. Simultaneously, the abutment portion 411 has a larger width than the guide hole 110; that is, the length of the abutment portion 411 along the width of the guide hole 110 is greater than the width of the guide hole 110, thus allowing the base 410 to be stably engaged in the guide hole 110. During installation, the guide hole 110 is stretched along its width direction to deform it, creating a larger opening so that the abutment portion 411 can extend from one end of the guide hole 110 to the other, thereby engaging the base 410 in the guide hole 110. Alternatively, the abutment portion 411 can also be engaged with the base 410 or detachably connected to the base 410 using screws or other fasteners.

[0051] The actuating mechanism 400 clamps the transmission component 320. When the user moves the actuating mechanism 400 along the direction from the second limit position 112 to the first limit position 111, the actuating mechanism 400 drives the transmission component 320 to move, thereby driving the lifting rod 330 to rotate. This causes the lifting rod 330 to lower the support component 100 relative to the fixed seat 310, thus adjusting the shelf 200 to descend. If further adjustment of the shelf 200 is needed, the actuating mechanism 400 can be released from the transmission component 320, and then moved towards the second limit position 112. Then, the actuating mechanism 400 clamps the transmission component 320 again and moves towards the first limit position 111. By repeating this adjustment step, the shelf 200 can be adjusted to a suitable height. In this application's shelf assembly, the length of the guide hole 110 can be set relatively small, allowing the actuating mechanism 400 to move back and forth within a small range, thus increasing the range of adjustable shelf height and improving the convenience of shelf 200 adjustment. Furthermore, after adjusting the shelf 200 to the appropriate position, the actuating mechanism 400 releases the transmission component 320, and then the actuating mechanism 400 is moved along the guide hole 110 to the appropriate position to prevent the actuating mechanism 400 from blocking the placement of items.

[0052] It should be noted that when the actuating mechanism 400 clamps the transmission component 320 and slides it from the first limit position 111 to the second limit position 112, it can also drive the shelf 200 to descend, and when it slides from the second limit position 112 to the first limit position 111, it can drive the shelf 200 to rise. The specific implementation can be determined according to the actual situation, and no specific limitation is made here.

[0053] Refer to Figure 4 and Figure 8 The base 410 is provided with a first handle 414. The first handle 414 is located on the side of the base 410 opposite to the second connecting part 416, that is, at the bottom end of the support member 100, or it can be located on the side of the support member 100. The user can move the actuating mechanism 400 by moving the first handle 414. By providing the first handle 414, it is more convenient for the user to move the actuating mechanism 400 from the first extreme position 111 to the second extreme position 112, or from the second extreme position 112 to the first extreme position 111. It should be noted that the first extreme position 111 and the second extreme position 112 can also be located in the middle of the guide hole 110. That is, when the shelf assembly is installed in the inner cavity of the refrigerator, and items are placed on the lower side of the shelf assembly, the end of the guide hole 110 may be blocked, making it impossible to move the actuating mechanism 400 to the end of the guide hole 110. In this case, the first extreme position 111 and the second extreme position 112 can be adjusted according to the actual situation.

[0054] In some embodiments of the present invention, the actuating mechanism 400 further includes a first elastic element 430, which may be a spring. One end of the first elastic element 430 abuts against the clamping member 420, and the other end abuts against the base 410. That is, when the first elastic element 430 is in a compressed state, it pushes the clamping member 420, causing the clamping member 420 to move towards the blocking portion 411, thereby enabling it to cooperate with the blocking portion 411 to clamp the transmission member 320. By providing the first elastic element 430, the actuating mechanism 400 can automatically clamp the transmission member 320 without requiring the user to manually push the clamping member 420, thus improving the convenience of using the shelf assembly.

[0055] In some embodiments of the present invention, reference is made to... Figure 7 to Figure 9 The clamping member 420 is further provided with a first connecting portion 423 and a clamping portion 421. The abutting portion 411 is provided with a through hole to form a hollow portion 4111, which is used to avoid the first connecting portion 423. The first connecting portion 423 passes through the hollow portion 4111. The actuating mechanism 400 also includes a first baffle 422, which is engaged on the side of the first connecting portion 423 away from the clamping portion 421. That is, the first baffle 422 and the clamping portion 421 are located on opposite sides of the abutting portion 411. One end of the first elastic member 430 abuts against the first baffle 422, and the other end abuts against the abutting portion 411. The first elastic member 430 pushes the first baffle 422, thereby pushing the clamping member 420 to move, so that the clamping portion 421 moves toward the abutting portion 411, thereby cooperating with the abutting portion 411 to clamp the transmission member 320. By inserting the first connecting portion 423 of the clamping member 420 into the hollow portion 4111 of the blocking portion 411, the inner wall of the hollow portion 4111 can play a guiding role, thereby making the structure of the actuating mechanism 400 more compact and stable.

[0056] It should be noted that the transmission component 320 can be a synchronous belt or synchronous chain. The clamping part 421 has teeth on the side facing the abutment part 411 that mesh with the transmission component 320. The teeth of the clamping part mesh with the teeth of the transmission component 320, and the clamping part 421 can press the transmission component 320 towards the abutment part 411. One side of the transmission component 320 abuts against the abutment part 411, and the opposite side is engaged with the clamping part 421, thus clamping the transmission component 320 and enabling it to move. It should be noted that the teeth of the clamping part have multiple teeth to stably clamp the transmission component 320. That is, five, six, seven, or eight teeth can be provided, or other numbers can be used, depending on the actual situation, and no specific limitation is made here. It should be noted that the structure of the teeth of the clamping part can be set according to the type of transmission component 320 to be able to clamp the transmission component 320.

[0057] It should be noted that a snap-fit ​​hole is provided on one side of the first connecting part 423, and a protrusion is provided at one end of the first baffle 422. The protrusion can be inserted into the snap-fit ​​hole, thereby snapping into the first connecting part 423. T-shaped protrusions are also provided at both ends of the first connecting part 423 located at the snap-fit ​​hole. The corresponding ends of the first baffle 422 can be inserted into the T-shaped protrusions, thereby making the first baffle 422 more stable and improving the overall stability of the actuating mechanism 400.

[0058] It should also be noted that one end of the first elastic member 430 can also abut against the side of the clamping part 421 away from the teeth. An abutment position is provided on the base 410, and the other end of the first elastic member 430 abuts against the abutment position of the base 410, thereby pushing the clamping part 421 toward the blocking part 411 to cooperate with the blocking part 411 to clamp the transmission member 320.

[0059] In some embodiments of the present invention, reference is made to... Figure 8 and Figure 9 The blocking part 411 is also provided with a second baffle 4112. One end of the first elastic member 430 abuts against the second baffle 4112, and the other end abuts against the first baffle 422. Multiple first elastic members 430 are provided to increase the pushing force on the clamping part 421, enabling the clamping part 421 to stably hold the transmission member 320, preventing the transmission member 320 from loosening when the actuating mechanism 400 drives the transmission member 320 to move. Multiple partition plates 4113 are provided on the side of the first baffle 422 facing the first elastic member 430 to separate the multiple springs and prevent them from affecting each other. Two or three first elastic members 430 can be provided, depending on the actual situation, and are not specifically limited here.

[0060] It should be noted that the second baffle 4112 is integrally formed with the abutment portion 411 and is located on the side of the abutment portion 411 facing the clamping portion 421. The first elastic member 430 can extend into the abutment portion 411 and abut against the second baffle 4112. Combined with the partition plate 4113, this effectively limits the movement of the first elastic member 430, improving its stability. Alternatively, the second baffle 4112 can also be snapped onto the abutment portion 411. The snapping method is the same as that of the first baffle 422, and will not be described further here.

[0061] In some embodiments of the present invention, the actuating mechanism 400 further includes an adjusting member 440, which is slidably mounted on the base 410. The adjusting member 440 can slide to push the clamping member 420, thereby causing the clamping part 421 to move toward or away from the blocking part 411. When the adjusting member 440 pushes the clamping member 420 toward the blocking part 411, the clamping part 421 can cooperate with the blocking part 411 to clamp the transmission member 320, thereby causing the transmission member 320 to move to adjust the height of the shelf 200. When the adjusting member 440 pushes the clamping member 420 away from the blocking part 411, the clamping part 421 can release the transmission member 320 to adjust the position of the actuating mechanism 400.

[0062] In some embodiments of the present invention, see also Figure 8 and Figure 9 The adjusting member 440 is provided with an abutment rod 441, and the clamping member 420 is provided with an inclined hole 425. The abutment rod 441 is slidably installed in the inclined hole 425, so that the moving direction of the adjusting member 440 is perpendicular to the moving direction of the clamping member 420. That is, the back-and-forth movement of the adjusting member 440 can drive the clamping member 420 to move left and right. One end of the abutment rod 441 passes through the inclined hole 425 and can slide along the length of the inclined hole 425. The inner wall of the inclined hole 425 forms an abutment portion 424, and the side wall of the abutment rod 441 abuts against the abutment portion 424. The adjusting member 440 slides toward the blocking portion 411, and the abutment rod 441 can drive the clamping member 420 to move and cause the clamping portion 421 to move away from the blocking portion 411, so as to release the transmission member 320. When the adjusting member 440 slides away from the blocking part 411, the abutting rod 441 can drive the clamping member 420 to move, and cause the clamping part 421 to move towards the blocking part 411 to clamp the transmission member 320. The clamping member 420 is provided with an inclined hole 425, and the abutting rod 441 passes through the inclined hole 425, with the side wall of the abutting rod 441 abutting against the inner wall of the inclined hole 425 to push the clamping member 420 to move. The inclined hole 425 can limit the adjustment member 440.

[0063] It should be noted that the inclined hole 425 has a certain angle with the sliding direction of the abutment part 424 toward the blocking part 411. This angle is greater than 0° and less than 90°, such as 45° or 60°, or other angles, so that when the adjusting member 440 slides, the abutment rod 441 can abut against the inner wall of the inclined hole 425, thereby pushing the clamping member 420 to move. The specific size of the angle can be determined according to the actual situation and is not specifically limited here. It should be noted that the moving direction of the adjusting member 440 and the moving direction of the clamping member 420 can be 90°, so that the adjusting member 440 can push the clamping member 420, thereby causing the clamping part 421 to move toward or away from the blocking part 411. Of course, other angles are also possible to adapt to the actual situation.

[0064] It should also be noted that the abutment rod 441 can be cylindrical to reduce the contact area with the abutment part 424, thereby reducing friction and allowing the abutment rod 441 to slide more smoothly along the length of the inclined hole 425. Of course, the abutment rod 441 can also adopt other shapes, such as a polygonal prism shape. The shape of the abutment rod 441 can be selected according to the specific situation, and no specific limitation is made here.

[0065] It should also be noted that the adjusting component 440 is provided with a mounting hole 513, and the abutment rod 441 is connected to the mounting hole 513 by an interference fit. Alternatively, the mounting hole 513 can also be a threaded hole, with the outer wall of the abutment rod 441 having threads, and the abutment rod 441 is screwed into the threaded hole. Of course, the abutment rod 441 can also be integrally formed with the adjusting component 440. The specific choice depends on the actual situation and is not specifically limited here.

[0066] In some embodiments of the present invention, a guide groove 412 is further provided on one side of the base 410, and an adjusting member 440 is slidably mounted in the guide groove 412. The adjusting member 440 can slide along the guide groove 412 to push the clamping member 420, thereby causing the clamping part 421 to move toward or away from the blocking part 411. (See reference...) Figure 7 and Figure 8 When the adjusting member 440 slides along the guide groove 412 from the inside to the outside, the abutting rod 441 can push the clamping member 420 to move, so that the clamping part 421 moves toward the blocking part 411 to clamp the transmission member 320. When the adjusting member 440 slides along the guide groove 412 from the outside to the inside, the abutting rod 441 can push the clamping member 420 to move, so that the clamping part 421 moves away from the blocking part 411 to release the transmission member 320.

[0067] In some embodiments of the present invention, the inner wall of the guide groove 412 is provided with a limiting groove 415, and the adjusting member 440 is provided with a limiting block 442. The limiting block 442 is disposed within the limiting groove 415 and can slide along the limiting groove 415. The limiting groove 415 is located on both sides of the inner wall of the guide groove 412, and two limiting blocks 442 are correspondingly provided on both sides of the adjusting member 440. The limiting blocks 442 can be inserted into the limiting groove 415 and can slide within the limiting groove 415. By providing the limiting blocks 442 and correspondingly providing the limiting groove 415 on the inner wall of the guide hole 110, the stability of the adjusting member 440 during operation can be improved.

[0068] In some embodiments of the present invention, reference is made to... Figure 8 and Figure 9The actuating mechanism 400 also includes a second elastic element 450, which can be a spring. One end of the second elastic element 450 abuts against the base 410, and the other end abuts against the adjusting member 440. The second elastic element 450 can push the adjusting member 440, thereby causing the adjusting member 440 to push the clamping part 421 towards the blocking part 411, so that the clamping part 421 cooperates with the blocking part 411 to clamp the transmission member 320. By having the second elastic element 450 push the adjusting member 440, causing the adjusting member 440 to push the clamping part 421 towards the blocking part 411, thus clamping the transmission member 320, the user does not need to manually push the clamping part 421 to clamp the transmission member 320, improving the convenience for the user when adjusting the shelf assembly.

[0069] It should be noted that the base 410 is provided with a limiting hole 413, and the second elastic element 450 is partially inserted into the limiting hole 413, and then refer to Figure 10 It should be noted that the adjusting member 440 is also provided with a first limiting rod 444, and one end of the second elastic member 450 is sleeved on the first limiting rod 444 and abuts against the adjusting member 440. By providing the first limiting rod 444 and the limiting hole 413 of the base 410, the stability of the second elastic member 450 can be improved, thereby improving the stability of the adjusting member 440 when sliding.

[0070] In some embodiments of the present invention, the clamping member 420 is provided with two inclined holes 425, which are symmetrically arranged on both sides of the clamping member 420. Correspondingly, two adjusting members 440 are also provided, located on both sides of the base 410 and cooperating with the inclined holes 425. The two adjusting members 440 can move towards each other to drive the clamping part 421 away from the blocking part 411. The two adjusting members 440 can also move in opposite directions to drive the clamping part 421 towards the blocking part 411. It should be noted that the adjusting member 440 is also provided with a second handle 443, which protrudes downward and is located at the bottom end of the support member 100. Of course, the second handle 443 can also be provided on the side of the support member 100, so as to facilitate pushing the adjusting member 440.

[0071] Understandably, combined with Figure 4 When the user needs to adjust the position of the toggle mechanism 400, they can simultaneously squeeze the second handles 443 of the adjusting members 440 on both sides of the base 410. By squeezing, the two adjusting members can simultaneously push the clamping member 420 to move, thereby moving the clamping part 421 away from the blocking part 411, thus releasing the transmission member 320, and then pushing the toggle mechanism 400 to move it to the appropriate position. After the toggle mechanism 400 has moved to the appropriate position, the user can release the second handles 443 on both sides, and the clamping part 421 can then move towards the blocking part 411 again to cooperate with the blocking part 411 to clamp the transmission member 320.

[0072] In some embodiments of the present invention, see also Figure 2 to Figure 4 The support member 100 has a first side 160, a second side 170, and a third side 180. One end of the first side 160 is connected to one end of the third side 180, and one end of the second side 170 is connected to one end of the third side 180, forming an opening between the first side 160 and the second side 170. Four lifting rods 330 are provided, respectively located at both ends of the first side 160 and the second side 170, and tension wheels 120 are located at both ends of the third side 180. A transmission member 320 is sequentially wound around the lifting rods 330 and the tension wheels 120 to form a closed loop. It should be noted that the upper end of the lifting rod 330 abuts against the support member 100 and is rotatable relative to it. The rotation of the transmission member 320 drives the four lifting rods 330 to rotate, causing the support member 100 to rise or fall relative to the fixed seat 310, thereby adjusting the rise or fall of the shelf 200. In the technical solution of this application, since the front ends of the first side 160 and the second side 170 have openings, when a user places items under the shelf assembly, the front side of the support member 100 will not obstruct the placement of items into the refrigerator. For example, when items are tall, there is no need to tilt them before placing or removing them, thus enabling the placement of taller items. Therefore, by designing the support member 100 with a three-sided structure, the front end of the support member 100 can avoid obstructing items, making it convenient for users to place and retrieve items, and saving space inside the refrigerator cavity to accommodate taller items, thereby improving the user experience.

[0073] In some embodiments of the present invention, reference is made to... Figure 2 The shelf assembly also includes a first cover plate 130, a second cover plate 140, and a third cover plate 150. Two first cover plates 130 and two second cover plates 140 are provided, with the two first cover plates 130 respectively covering the upper sides of the first side 160 and the second side 170. Two second cover plates 140 are respectively covering the first side 160 and the second side 170, and are located above the first cover plates 130. The second cover plates 140 are snapped into the support member 100. The third cover plate 150 is also snapped into the support member 100 and covers the third side 180.

[0074] It should be noted that the shelf 200 is placed on top of the second cover plate 140 and the third cover plate 150, and is fixed to the support member 100 by a movable buckle. At the same time, the third side 180 is provided with a snap-fit ​​part 181, which is groove-shaped. One side of the shelf 200 is inserted into the snap-fit ​​part 181 to limit the shelf 200.

[0075] It should also be noted that, described in terms of the orientation of the shelf assembly after it is installed inside the refrigerator cavity, the third side 180 is located at the rear of the refrigerator cavity, the first side 160 is located on the left side of the refrigerator cavity, and the second side 170 is located on the right side of the refrigerator cavity. By placing the third side 180 at the rear, the space on the front is not occupied by the side of the shelf assembly, thus saving some space.

[0076] It should also be noted that the actuating mechanism 400 is installed on the first side 160, and the first side 160 is provided with a guide hole 110. When the actuating mechanism 400 clamps the transmission member 320, pushing the actuating mechanism 400 from front to back can adjust the shelf 200 to rise, and pushing it from back to front can adjust the shelf 200 to fall. Of course, the actuating mechanism 400 can also be set on the second side 170 or the third side 180. When set on the third side 180, it moves left or right along the third side 180 to drive the transmission member 320 to move.

[0077] In some embodiments of the present invention, see also Figure 3 The shelving assembly also includes a tensioning assembly 500, located on the third side 180, for tensioning the transmission component 320, enabling the transmission component 320 to rotate smoothly and drive the lifting rod 330 to rotate. (See also...) Figure 13 and Figure 14 The tensioning assembly 500 includes a first tensioning member 510 and a second tensioning member 520, which are elastically connected. One end of the transmission member 320 is connected to the first tensioning member 510, and the other end is connected to the second tensioning member 520 to tension the transmission member 320, thereby putting the transmission member 320 in a tensioned state.

[0078] The first tensioning member 510 includes a mounting groove 512. A second tensioning member 520 is disposed within the mounting groove 512 and is slidable within it. The side wall of the mounting groove 512 has a mounting hole 513. The second tensioning member 520 has a second limiting rod 523, which passes through the mounting hole 513 and is slidable along the axial direction of the mounting hole 513. A third elastic member 522 is sleeved on the second limiting rod 523. One end of the third elastic member 522 abuts against the inner wall of the mounting groove 512, and the other end abuts against the second tensioning member 520. The third elastic member 522 can be a spring.

[0079] It should be noted that the first tensioning member 510 has a first locking tooth portion 511, which has locking teeth for engaging with the transmission member 320. Multiple locking teeth are provided, such as five, six, seven, or other numbers. One end of the transmission member 320 is engaged with multiple locking teeth, and the tension of the transmission member 320 can be adjusted according to the number of locking teeth engaged. The second tensioning member 520 has a second locking tooth portion 521, which has locking teeth for engaging with the transmission member 320. Multiple locking teeth are provided, such as five, six, seven, or other numbers. One end of the transmission member 320 is engaged with multiple locking teeth, and the tension of the transmission member 320 can be adjusted according to the number of locking teeth engaged.

[0080] A refrigerator according to a second aspect of the present invention includes a shelf assembly according to the first aspect embodiment. The shelf assembly is disposed within the refrigerator's interior cavity; that is, the shelf assembly can be fixedly installed on the inner wall of the refrigerator's interior cavity via a fixing seat 310. Shelves 200 are used to place items, and a support member 100 can raise or lower the shelves 200 to adjust their height, thereby improving the utilization rate of the refrigerator's interior cavity or facilitating the placement or retrieval of items. Furthermore, the shelf assembly divides the refrigerator's interior cavity, improving its utilization rate. By adjusting the height of the shelves 200, it can accommodate items of different heights, improving the convenience of using the refrigerator. Simultaneously, the refrigerator also possesses at least all the beneficial effects of the shelf assembly described in the first aspect embodiment, which will not be elaborated upon here.

[0081] It should be noted that multiple shelf assemblies can be installed in the refrigerator cavity, that is, two, three or four, etc., depending on the specific circumstances, and no specific limitation is made here.

[0082] It should also be noted that shelving assemblies can also be installed within the cavities of other devices to divide those cavities. That is, they can be installed in cabinets or storage units, as well as other devices that require cavities to be divided using shelving assemblies, thereby improving the utilization rate of the cavities within cabinets or storage units and facilitating the storage or retrieval of items.
