[0027] For convenience of describing this embodiment, as shown in Fig. 1, the left-right direction is the length direction of the shelf, namely the first direction, and the front-rear direction is as shown in Fig. 1.

[0028] With reference to Figs. 1 to 9, an embodiment of the present disclosure provides a shelf assembly, the shelf assembly including: a shelf 10, a support member 20, a first telescopic member 30, a second telescopic member 40 and an operating portion 50. The shelf 10 is provided with a guide portion 11 extending along a length direction of the shelf 10, and the guide portion 11 may be a slide groove or a slide block; the support member 20 is disposed on the shelf 10; the first telescopic member 30 is movably connected to the support member 20 and the first telescopic member 30 is slidably connected to the guide portion 11; the second telescopic member 40 is slidably connected to the guide portion 11, and along the first direction, the first telescopic member 30 and the second telescopic member 40 are respectively disposed at both ends of the support member 20.

[0029] The shelf assembly further includes an operating portion 50 disposed on the support member 20, the operating portion 50 is operably movable along a second direction, the second direction intersects with the first direction, and the second direction is a movement direction of the operating portion 50; with movement of the operating portion 50, the first telescopic member 30 and the second telescopic member 40 move toward each other along the first direction to cause the first telescopic member 30 and the second telescopic member 40 to retract into the shelf 10; or with movement of the operating portion 50, the first telescopic member 30 and the second telescopic member 40 move away from each other along the first direction to cause the first telescopic member 30 and the second telescopic member 40 to extend from the shelf 10.

[0030] Optionally, the operating portion 50 is movably connected to the support member 20, the first telescopic member 30 is provided with a first slide channel 31, and the first slide channel 31 extends obliquely along the length direction of the shelf 10. The second telescopic member 40 is partially nested in the first telescopic member 30, the second telescopic member 40 is provided with a second slide channel 41, the second slide channel 41 extends obliquely along the length direction of the shelf 10 and is inclined in a same direction as the first slide channel 31, and the second slide channel 41 and the first slide channel 31 are arranged in partial overlapping arrangement. The operating portion 50 extends through the first slide channel 31 and the second slide channel 41. A movement direction of the operating portion 50 intersects with the length direction of the shelf 10. When the operating portion 50 moves along the second direction, the first telescopic member 30 and the second telescopic member 40 simultaneously extend and retract along the length direction of the shelf 10 under driving of the operating portion 50.

[0031] By adopting the embodiments of the present disclosure, by providing the guide portion 11 extending along the length direction of the shelf 10 on the shelf 10, and arranging both the first telescopic member 30 and the second telescopic member 40 to be slidably connected to the guide portion 11, under limitation of the guide portion 11, the first telescopic member 30 and the second telescopic member 40 can only move along the length direction of the shelf 10, so that the first telescopic member 30 and the second telescopic member 40 can extend from or retract into the shelf 10, wherein the length direction of the shelf 10 is also the left-right direction in Fig. 1.

[0032] By providing the support member 20 and movably connecting the first telescopic member 30 to the support member 20, the support member 20 can support the first telescopic member 30, and the first telescopic member 30 can move relative to the support member 20 along the left-right direction. By providing the second telescopic member 40 and arranging the second telescopic member 40 to be partially nested with the first telescopic member 30, the first telescopic member 30 can support the second telescopic member 40, and the second telescopic member 40 can move relative to the first telescopic member 30 along the left-right direction. By movably connecting the operating portion 50 to the support member 20, the support member 20 can support the operating portion 50 and the operating portion 50 can move relative to the support member 20.

[0033] By arranging the movement direction of the operating portion 50 to intersect with the length direction of the shelf 10, that is to say, the movement direction of the operating portion 50 does not move along the left-right direction. By providing the first slide channel 31 on the first telescopic member 30 and the second slide channel 41 on the second telescopic member 40, and arranging the operating portion 50 to extend through the first slide channel 31 and the second slide channel 41, the operating portion 50 can be connected to both the first slide channel 31 and the second slide channel 41. When the operating portion 50 moves, under limitation of the guide portion 11 of the shelf 10 and the first slide channel 31 and the second slide channel 41, the first telescopic member 30 or the second telescopic member 40 will not move along the movement direction of the operating portion 50, and under limitation of the first slide channel 31 and the second slide channel 41, the movement of the operating portion 50 can be converted into movement along the left-right direction, so that the first telescopic member 30 and the second telescopic member 40 simultaneously perform telescopic movement along the left-right direction under driving of the operating portion 50. That is to say, when the operating portion 50 moves, the first telescopic member 30 and the second telescopic member 40 can move toward each other or move away from each other, so that the first telescopic member 30 and the second telescopic member 40 retract into or extend from the shelf 10. When an end of the first slide channel 31 facing toward the second slide channel 41 coincides with an end of the second slide channel 41 facing toward the first slide channel 31, the first telescopic member 30 and the second telescopic member 40 are in an extended position; when an end of the first slide channel 31 facing away from the second slide channel 41 coincides with an end of the second slide channel 41 facing away from the first slide channel 31, the first telescopic member 30 and the second telescopic member 40 are in a retracted position, and the first telescopic member 30 and the second telescopic member 40 can move between the extended position and the retracted position under driving of the operating portion 50. Compared with the adjustment method in the related technology, this embodiment only needs to adjust the position of the operating portion 50 to make the first telescopic member 30 and the second telescopic member 40 simultaneously extend or retract, which can effectively improve the convenience of user operation.

[0034] In some embodiments, as shown in Figs. 1 and 3, the shelf 10 has two slide grooves 11 extending along the left-right direction, the slide grooves 11 include a first slide groove and a second slide groove, the first slide groove corresponds to the first telescopic member 30, the first telescopic member 30 is provided with a first slide block adapted to the first slide groove, the second slide groove corresponds to the second telescopic member 40, and the second telescopic member 40 is provided with a second slide block adapted to the second slide groove.

[0035] Optionally, a dimension of the first slide groove along the length direction of the shelf 10 is equal to a distance between a first end of the first slide channel 31 and a second end of the first slide channel 31.

[0036] In this way, the first slide groove and the first slide block, as well as the operating portion 50 and the first slide channel 31, can jointly limit the moving distance of the first telescopic member 30, avoiding situations where the operating portion 50 and the first slide channel 31 are subjected to excessive force leading to fracture or damage.

[0037] Optionally, both ends of the first slide groove are provided with buffer members.

[0038] In this way, by providing buffer members, the impact between the first telescopic member 30 and the first slide groove of the shelf 10 can be mitigated, reducing impact noise.

[0039] Optionally, a dimension of the second slide groove along the length direction of the shelf 10 is equal to a distance between a first end of the second slide channel 41 and a second end of the second slide channel 41.

[0040] In this way, the second slide groove and the second slide block, as well as the operating portion 50 and the second slide channel 41, can jointly limit the moving distance of the second telescopic member 40, avoiding situations where the operating portion 50 and the second slide channel 41 are subjected to excessive force leading to fracture or damage.

[0041] Optionally, both ends of the second slide groove are provided with buffer members.

[0042] In this way, by providing buffer members, the impact between the second telescopic member 40 and the second slide groove of the shelf 10 can be mitigated, reducing impact noise.

[0043] In some embodiments, the buffer members may be rubber pads or silicone pads. It can be understood that the specific form of the buffer members is not unique.

[0044] Optionally, an angle between the movement direction of the operating portion 50, namely the second direction, and the length direction of the shelf 10 is 90 degrees.

[0045] In this way, by designing the first slide channel 31 and the second slide channel 41 symmetrically about the operating portion 50, when the operating portion 50 rotates, the first telescopic member 30 and the second telescopic member 40 can move the same distance.

[0046] Optionally, the first telescopic member 30 has a cylindrical structure, the second telescopic member 40 has a cylindrical structure, and an outer wall of the second telescopic member 40 abuts against an inner wall of the first telescopic member 30; wherein the first slide channel 31 and the second slide channel 41 are both helical, and the helical structures of the first slide channel 31 and the second slide channel 41 are each less than one complete turn.

[0047] By adopting the embodiments of the present disclosure, by configuring the first telescopic member 30 as a cylindrical structure and the second telescopic member 40 as a cylindrical structure, not only is it convenient to connect the second telescopic member 40 to the first telescopic member 30, but the production cost of the first telescopic member 30 and the second telescopic member 40 can also be reduced. By having the outer wall of the second telescopic member 40 abut against the inner wall of the first telescopic member 30, the second telescopic member 40 can be nested within the first telescopic member 30, utilizing the first telescopic member 30 to support the second telescopic member 40, avoiding increased movement resistance from connecting the second telescopic member 40 to the shelf 10.

[0048] By configuring the first slide channel 31 and the second slide channel 41 as helical structures with less than one complete turn, since under limitation of the slide groove 11 of the shelf 10, the first telescopic member 30 and the second telescopic member 40 can only move along the left-right direction, the first slide channel 31 and the second slide channel 41 can also only move along the left-right direction, and the operating portion 50 rotates relative to the first telescopic member 30. By setting the helical structure to less than one complete turn, the first telescopic member 30 and the second telescopic member 40 can complete retraction or extension without requiring the operating portion 50 to rotate one complete turn or multiple turns, thereby enabling the first telescopic member 30 and the second telescopic member 40 to quickly retract or extend, improving the convenience of user operation.

[0049] It should be noted that the first telescopic member 30 and the second telescopic member 40 may have square structures, with the first slide channel 31 disposed on an upper surface of the first telescopic member 30 and the second slide channel 41 disposed on an upper surface of the second telescopic member 40. It can be understood that the specific structural shapes of the first telescopic member 30 and the second telescopic member 40 are not unique, including but not limited to cylindrical structures.

[0050] Optionally, an angle between a connecting line from a first end of the first slide channel 31 to an axis of the first telescopic member 30 and a connecting line from a second end of the first slide channel 31 to the axis of the first telescopic member 30 is greater than 30 degrees and less than 180 degrees.

[0051] By adopting the embodiments of the present disclosure, when the angle is less than 30 degrees, the resistance for the user to rotate the operating portion 50 is large, making it difficult for the user to rotate the operating portion 50; when the angle is greater than 180 degrees, the angle through which the user needs to rotate the operating portion 50 is too large, making it inconvenient for the user to use.

[0052] Optionally, an angle between a connecting line from a first end of the second slide channel 41 to an axis of the second telescopic member 40 and a connecting line from a second end of the second slide channel 41 to the axis of the second telescopic member 40 is greater than 30 degrees and less than 180 degrees.

[0053] In this way, when the angle is less than 30 degrees, the resistance for the user to rotate the operating portion 50 is large, making it difficult for the user to rotate the operating portion 50; when the angle is greater than 180 degrees, the angle through which the user needs to rotate the operating portion 50 is too large, making it inconvenient for the user to use.

[0054] Optionally, an angle between a first connecting line and a second connecting line is 90 degrees, the first connecting line being a connecting line from a first end of the first slide channel 31 to an axis of the first telescopic member 30, and the second connecting line being a connecting line from a second end of the first slide channel 31 to the axis of the first telescopic member 30; and an angle between a third connecting line and a fourth connecting line is 90 degrees, the third connecting line being a connecting line from a first end of the second slide channel 41 to an axis of the second telescopic member 40, and the fourth connecting line being a connecting line from a second end of the second slide channel 41 to the axis of the second telescopic member 40.

[0055] In this way, not only can the problem of the angle being too small, causing the user to encounter large rotational resistance making it difficult to rotate, be avoided, but also the problem of the angle being too large, requiring the user to rotate through a large angle, making it difficult for the user to operate, can be avoided.

[0056] Optionally, the shelf assembly further includes: a first elastic member 60, the first elastic member 60 is disposed within the first telescopic member 30, one end of the first elastic member 60 is connected to the first telescopic member 30, and another end of the first elastic member 60 is connected to the second telescopic member 40; wherein when the first telescopic member 30 and the second telescopic member 40 move toward each other, the first elastic member 60 is compressed.

[0057] By adopting the embodiments of the present disclosure, by providing the first elastic member 60, the first elastic member 60 can drive the second telescopic member 40 to move in a direction away from the first telescopic member 30, that is to say, the first elastic member 60 can cause the second telescopic member 40 and the first telescopic member 30 to move away from each other. In this way, the first elastic member 60 can cause the first telescopic member 30 and the second telescopic member 40 to automatically extend. When the first telescopic member 30 and the second telescopic member 40 move toward each other, by setting the first elastic member 60 to be compressed, that is to say, the first elastic member 60 can drive the second telescopic member 40 and the first telescopic member 30 to both move to the extended position, ensuring that the second telescopic member 40 and the first telescopic member 30 are always positioned in the extended position, avoiding situations where the first telescopic member 30 and the second telescopic member 40 retract due to vibration or other reasons, which would cause the shelf 10 to be unable to be fixed. In addition, when the first telescopic member 30 and the second telescopic member 40 move toward each other, by setting the first elastic member 60 to be compressed, that is to say, when the second telescopic member 40 is positioned at the retracted position, the compression amount of the first elastic member 60 reaches maximum, which can avoid situations where the user rotates the operating portion 50 too quickly, causing the operating portion 50 to collide with an end of the corresponding slide groove 11, leading to damage or fracture.

[0058] It should be noted that the first elastic member 60 may be a spring, or may be a polyurethane elastomer, or may be a rubber elastomer, etc. It can be understood that the specific form of the first elastic member 60 is not unique.

[0059] Optionally, the support member 20 includes: a support base 21, a middle part of the support base 21 defines a mounting opening 211, the mounting opening 211 is adapted to the first telescopic member 30, so that the support base 21 nests the first telescopic member 30.

[0060] By adopting the embodiments of the present disclosure, by providing the support base 21 and defining the mounting opening 211 adapted to the first telescopic member 30 in the middle part of the support member 20, the first telescopic member 30 can be inserted into the support base 21 through the mounting opening 211, so that the support base 21 nests the first telescopic member 30 and supports the first telescopic member 30.

[0061] In some embodiments, the mounting opening 211 extends along the left-right direction, enabling the first telescopic member 30 to extend into the support base 21 relative to the support base 21 along the left-right direction.

[0062] Optionally, the support member 20 is disposed on an upper end surface of the shelf 10 and located at a rear part of the shelf 10.

[0063] In this way, by disposing the support member 20 at the rear part of the shelf 10, the first telescopic member 30 and the second telescopic member 40 are also disposed at the rear part of the shelf 10, which can avoid the first telescopic member 30 and the second telescopic member 40 from blocking users from placing items, ensuring convenience for users to place items on the shelf 10. Moreover, compared with the arrangement in the related technology, when the device in the related technology is disposed at the rear part of the shelf 10, it is very inconvenient for users to operate. The arrangement position of this embodiment facilitates user operation of the operating portion 50 connected to the support member 20, improving the convenience of user use.

[0064] Optionally, the support member 20 is disposed at a front end of the shelf 10.

[0065] In this way, it can facilitate user operation of the operating portion 50, improving the convenience for users to use the shelf assembly.

[0066] Optionally, both sides of the support base 21 are respectively provided with a first track 212 and a second track, the first track 212 and the second track both extend along a wall surface of the first telescopic member 30; the support member 20 further includes: a connecting frame 22 defining a through hole 221, the through hole 221 is adapted to the operating portion and is slidably connected to both the first track 212 and the second track, so that the operating portion is slidably connected to the support base 21.

[0067] By adopting the embodiments of the present disclosure, by providing the first track 212 and the second track on the support base 21, and slidably connecting the connecting frame 22 to the first track 212 and the second track, the connecting frame 22 can slide relative to the support base 21 along the first track 212 and the second track. By disposing the first track 212 and the second track on both sides of the support base 21, the connection reliability between the connecting frame 22 and the support base 21 can be ensured.

[0079] In this way, since the interior of the refrigeration device is in a low temperature environment for a long time, due to condensation, internal items will have a certain adhesion force, making them difficult to move. By setting the helical angle of the first slide segment 311 to be smaller than the helical angle of the second slide segment 312, when the operating portion 50 moves along the first slide segment 311, compared to the operating portion 50 sliding along the second slide segment 312, when the operating portion 50 rotates through the same angle, the distance moved by the first telescopic member 30 is smaller, that is to say, the retraction distance of the first telescopic member 30 is shorter. When the user initially rotates the operating portion 50, the first telescopic member 30 can have a larger acceleration, and the user can drive the first telescopic member 30 to extend and retract with less force, improving the convenience of user operation. In addition, when the first telescopic member 30 is extending, when the operating portion 50 moves from the second slide segment 312 to the first slide segment 311, the extension speed of the first telescopic member 30 can be reduced, reminding the user that the first telescopic member 30 is about to reach the extended position, avoiding the following problems: the user rotates the operating portion 50 too quickly, or the first elastic member 60 drives the first telescopic member 30 to automatically extend at too high a rate, causing the operating portion 50 to impact the end of the first slide channel 31, resulting in fracture of the operating portion 50 or damage to the first slide channel 31.

When the first telescopic member 30 is extending, the first telescopic member 30 can have a larger acceleration, facilitating driving the first telescopic member 30 to move, and even when the driving force of the first elastic member 60 continuously decreases, the operating portion 50 can still slide to the first slide segment 311 under the elastic force of the first elastic member 60, enabling the first telescopic member 30 to extend a sufficient distance.

[0082] Optionally, the second slide channel 41 includes a fourth slide segment 411 and a fifth slide segment 412, the fourth slide segment 411 is located at an end of the second slide channel 41 facing toward the first telescopic member 30, the fourth slide segment 411 is connected to the fifth slide segment 412, wherein an angle of a helical angle of the fourth slide segment 411 is smaller than an angle of a helical angle of the fifth slide segment 412.

[0083] In this way, since the interior of the refrigeration device is in a low temperature environment for a long time, due to condensation, internal items will have a certain adhesion force, making them difficult to move. By setting the helical angle of the fourth slide segment 411 to be smaller than the helical angle of the fifth slide segment 412, when the operating portion 50 moves along the fourth slide segment 411, compared to the operating portion 50 sliding along the fifth slide segment 412, when the operating portion 50 rotates through the same angle, the distance moved by the second telescopic member 40 is smaller, that is to say, the retraction distance of the second telescopic member 40 is shorter. When the user initially rotates the operating portion 50, the second telescopic member 40 can have a larger acceleration, and the user can drive the second telescopic member 40 to extend and retract with less force, improving the convenience of user operation. In addition, when the second telescopic member 40 is extending, when the operating portion 50 moves from the fifth slide segment 412 to the fourth slide segment 411, the extension speed of the second telescopic member 40 can be reduced, reminding the user that the second telescopic member 40 is about to reach the extended position, avoiding the following problems: the user rotates the operating portion 50 too quickly, or the first elastic member 60 drives the second telescopic member 40 to automatically extend at too high a rate, causing the operating portion 50 to impact the end of the second slide channel 41, resulting in fracture of the operating portion 50 or damage to the second slide channel 41.

[0097] Optionally, the shelf assembly further includes: a sleeve 131, a fixing base 32 and a connecting rod 33, one end of the sleeve 131 is disposed within the shaft cylinder and is slidably connected to the shaft cylinder, another end of the sleeve 131 extends toward a direction away from the shaft cylinder, an outer wall of the another end of the sleeve 131 is provided with a sliding portion 12; the fixing base 32 is disposed within the sleeve 131; the connecting rod 33 is disposed within the fixing base 32 and extends outside the sleeve 131 and is located within the slide groove 121, so that the connecting rod 33 is connected to the slide groove 121 of the shaft cylinder; wherein the shelf 10 is provided with a guide portion 11 adapted to the sliding portion 12, the sleeve 131 has an extended position and a retracted position, by rotating the shaft cylinder, the two sleeves 131 move between the extended position and the retracted position along an extending direction of the shaft cylinder, so that the sleeve 131 extends from the shelf 10 or retracts into the shelf 10.

[0098] By adopting the shelf assembly for a refrigeration device of the embodiments of the present disclosure, by providing the sliding portion 12 on the sleeve 131 and providing the guide portion 11 adapted to the sliding portion 12 on the shelf 10, the guide portion 11 can not only slidably connect the sleeve 131 to the shelf 10, but also prevent the sleeve 131 from rotating relative to the shaft cylinder, thereby enabling the sleeve 131 to be rotatably connected to the shaft cylinder, and when the shaft cylinder rotates, the sleeve 131 will not be driven to rotate.

[0099] By providing the connecting rod 33 and extending the connecting rod 33 into the slide groove 121, the sleeve 131 can be slidably connected to the slide groove 121 of the shaft cylinder, so that when the shaft cylinder rotates, the connecting rod 33 moves along the extending direction of the shaft cylinder under limitation of the slide groove 121, thereby causing the sleeve 131 to move between the extended position and the retracted position, so that the sleeve 131 extends from the shelf 10 to be adapted to connect with the refrigeration device or retracts into the shelf 10 to disconnect from the refrigeration device.

[0100] Optionally, the helical structure of the slide groove 121 is less than one complete turn, an angle between two connecting lines is greater than 30 degrees and less than 180 degrees, wherein one connecting line is a connecting line from a first end of the slide groove 121 to an axis of the shaft cylinder, and another connecting line is a connecting line from a second end of the slide groove 121 to the axis of the shaft cylinder.

In this way, the sleeve 131 can complete retraction without requiring the shaft cylinder to rotate one complete turn or multiple turns, thereby enabling the sleeve 131 to quickly retract or extend, improving the convenience of user operation. By setting the angle between the above two connecting lines to be greater than 30 degrees and less than 180 degrees, when the angle is less than 30 degrees, the resistance for the user to rotate the shaft cylinder is large, making it difficult for the user to rotate the shaft cylinder; when the angle is greater than 180 degrees, the angle through which the user needs to rotate the shaft cylinder is too large, making it inconvenient for the user to rotate the shaft cylinder.

[0102] Preferably, an angle between the two connecting lines is 90 degrees, wherein one connecting line is a connecting line from a first end of the slide groove 121 to an axis of the shaft cylinder, and another connecting line is a connecting line from a second end of the slide groove 121 to the axis of the shaft cylinder.

By setting the second elastic member 140 to be compressed when the sleeve 131 moves toward the shaft cylinder, that is to say, the second elastic member 140 can drive the sleeve 131 to move to the extended position, ensuring that the sleeve 131 is always positioned at the extended position, avoiding situations where the sleeve 131 retracts due to vibration or other reasons, which would cause the shelf 10 to be unable to be fixed. In addition, by setting the second elastic member 140 to be compressed when the sleeve 131 moves toward the shaft cylinder, that is to say, when the sleeve 131 is positioned at the retracted position, the compression amount of the second elastic member 140 reaches maximum, which can avoid situations where the user rotates the operating portion 50 too quickly, causing the connecting rod 33 to collide with an end of the slide groove 121, leading to damage or fracture.

[0130] In this way, by setting the opening area of the end of the mounting groove 122 facing away from the shaft cylinder to gradually decrease along the retraction direction of the sleeve 131, when connecting the telescopic assembly 30 to the shaft cylinder, the connecting rod 33 can be compressed by the end of the mounting groove 122, facilitating the connecting rod 33 to extend into the fixing base 32, so as to facilitate the telescopic assembly 30 to extend into the shaft cylinder, thereby improving the convenience of connection between the telescopic assembly 30 and the shaft cylinder.

[0131] Optionally, the shelf assembly for a refrigeration device further includes: an operating portion 50, the operating portion 50 is disposed on an outer wall surface of the shaft cylinder, so as to rotate the shaft cylinder.

[0132] By adopting the shelf assembly for a refrigeration device of the embodiments of the present disclosure, by providing the operating portion 50 and disposing the operating portion 50 on the outer wall surface of the shaft cylinder, the operating portion 50 can be configured as a handle, or can be configured as the outer wall surface of the shaft cylinder. The user can drive the shaft cylinder to rotate by rotating the handle, which is more convenient for user operation compared to directly rotating the shaft cylinder, reducing the difficulty of user operation, and allowing the shaft cylinder to be driven to rotate with less force.

[0133] In some embodiments, the operating portion 50 is disposed at a middle part of the shaft cylinder and corresponds to a second end of the slide groove 121.

[0134] In this way, by disposing the operating portion 50 at the middle part of the shaft cylinder and setting the operating portion 50 to correspond to the second end of the slide groove 121, the force applied to the operating portion 50 can be evenly applied to both sides of the shaft cylinder, ensuring uniform force distribution on the shaft cylinder and improving the reliability of the device.

[0135] Optionally, the operating portion 50 has a flat plate structure and extends along an extending direction of the shaft cylinder, and a length of the operating portion 50 is slightly smaller than a distance between the two slide grooves 121.

[0136] In this way, the grippable area of the operating portion 50 can be increased, further improving the convenience of user operation.

[0137] It should be noted that the operating portion 50 may also have a cylindrical structure, and the specific structural form of the operating portion 50 is not unique, including but not limited to the specific structural form in this embodiment, and can be flexibly adjusted.

[0138] Optionally, the shelf assembly for a refrigeration device further includes: brackets 160, the brackets 160 are disposed on the shelf 10, the number of brackets 160 is two, the two brackets 160 are respectively disposed on both sides of the shaft cylinder, and both are rotatably connected to the shaft cylinder.

[0139] By adopting the shelf assembly for a refrigeration device of the embodiments of the present disclosure, by providing the brackets 160, the shaft cylinder is ensured to be firmly connected to the shelf 10, and by providing two brackets 160 and disposing the two brackets 160 on both sides of the shaft cylinder, the brackets 160 can support both sides of the shaft cylinder, enabling the shaft cylinder to remain stable.

[0140] In some embodiments, the bracket 160 is a support plate defining a mounting opening, the mounting opening is adapted to the shaft cylinder, so that the bracket 160 is fitted on the shaft cylinder, and the two are rotatably connected.

[0141] In this way, the shaft cylinder can be installed in the mounting opening, so that the shaft cylinder is rotatably connected to the bracket 160.

[0142] Optionally, the slide groove 121 includes a first groove segment 1211 and a second groove segment 1212, the first groove segment 1211 is located at an end of the slide groove 121 facing toward the sleeve 131, the second groove segment 1212 is connected to the first groove segment 1211, wherein an angle of a helical angle of the first groove segment 1211 is smaller than an angle of a helical angle of the second groove segment 1212.

[0143] In this way, since the interior of the refrigeration device is in a low temperature environment for a long time, due to condensation, internal items will have a certain adhesion force, making them difficult to move. By setting the helical angle of the first groove segment 1211 to be smaller than the helical angle of the second groove segment 1212, when the connecting rod 33 moves along the first groove segment 1211, compared to the connecting rod 33 sliding along the second groove segment 1212, when the operating portion 50 rotates through the same angle, the distance moved by the connecting rod 33 is smaller, that is to say, the retraction distance of the sleeve 131 is shorter. When the user initially rotates the operating portion 50, the sleeve 131 can have a larger acceleration, and the user can drive the sleeve 131 to extend and retract with less force, improving the convenience of user operation. In addition, when the sleeve 131 is extending, when the connecting rod 33 moves from the second groove segment 1212 to the first groove segment 1211, the extension speed of the sleeve 131 can be reduced, reminding the user that the sleeve 131 is about to reach the extended position, avoiding problems where the user rotates the operating portion 50 too quickly or the second elastic member 140 drives the sleeve 131 to automatically extend at too high a rate, causing the connecting rod 33 to impact the end of the slide groove 121, resulting in fracture of the connecting rod 33 or damage to the slide groove 121.

[0144] Optionally, the slide groove 121 further includes: a third groove segment 1213, the third groove segment 1213 is located at an end of the slide groove 121 facing away from the sleeve 131, the third groove segment 1213 is connected to the second groove segment 1212, wherein an angle of a helical angle of the third groove segment 1213 is smaller than an angle of a helical angle of the second groove segment 1212.

[0145] In this way, by setting the helical angle of the third groove segment 1213 to be smaller than the helical angle of the second groove segment 1212, when the connecting rod 33 moves along the third groove segment 1213, compared to the connecting rod 33 sliding along the second groove segment 1212, when the operating portion 50 rotates through the same angle, the distance moved by the connecting rod 33 is smaller, that is to say, the moving distance of the sleeve 131 is shorter. When the sleeve 131 is retracting, the retraction speed of the sleeve 131 can be reduced, reminding the user that it is about to reach the retracted position, avoiding problems where the user rotates the operating portion 50 too quickly, causing the connecting rod 33 to impact the end of the slide groove 121, resulting in fracture of the connecting rod 33 or damage to the slide groove 121. When the sleeve 131 is extending, the sleeve 131 can have a larger acceleration, facilitating driving the sleeve 131 to move, and even when the driving force of the second elastic member 140 continuously decreases, the connecting rod 33 can still slide to the first groove segment 1211 under the elastic force of the second elastic member 140, enabling the sleeve 131 to extend a sufficient distance.

[0146] Optionally, the shaft cylinder is made of transparent material.

[0147] In this way, by making the shaft cylinder from transparent material, the user can clearly see the relative position of the connecting rod 33 and the slide groove 121, thereby intuitively determining whether the sleeve 131 is in the extended position or the retracted position, avoiding situations where the user cannot intuitively see the position of the connecting rod 33 relative to the slide groove 121 and performs incorrect operations.

[0151] In this way, by providing support ribs 71 on the inner liner 70, the support ribs 71 can support the shelf 10. By providing fixing holes and adapting the fixing holes to the first telescopic member 30 or the second telescopic member 40, when the first telescopic member 30 or the second telescopic member 40 extends from the shelf 10, the first telescopic member 30 or the second telescopic member 40 extends into the fixing hole of the corresponding side wall, which can limit the position of the shelf 10, thereby limiting the position of the shelf 10 relative to the inner liner 70.

[0152] Optionally, the number of support ribs 71 and fixing holes are both multiple, the number of fixing holes is the same as the number of support ribs 71, and the multiple support ribs 71 and multiple fixing holes are all spaced along a height direction of the inner liner 70.

[0153] In this way, the shelf 10 can be connected to any one of the multiple support ribs 71, flexibly adjusting the height position of the shelf 10 in the inner liner 70, and the shelf 10 can be connected to the fixing holes through the first telescopic member 30 and the second telescopic member 40 to limit the position of the shelf 10 relative to the inner liner 70.
