Description

Shelf assembly for refrigeration equipment and refrigeration equipment

[0001] This application is based on the Chinese patent application with application number 202311560911.5 and application date of November 22, 2023, and the Chinese patent application with application number 202311560916.8 and application date of November 22, 2023, and claims the priority of these two Chinese patent applications. The entire contents of the above patent applications are hereby introduced into this application as a reference. Technical Field

[0002] The present application relates to the technical field of household appliances, for example, to a shelf assembly for a refrigeration device and the refrigeration device. Background Art

[0003] A refrigerator is a refrigeration device that maintains a constant low temperature. It's also a consumer product designed to keep food and other items at a constant low temperature. Refrigerators are a necessity in modern families, especially in the summer, where food needs to be stored to prevent spoilage. To accommodate this need, refrigerators have shelves within their storage compartments.

[0004] At present, the shelves in the storage compartment of the refrigerator are generally supported and fixed by the ribs on the inner surface of the inner tank. Since the shelves in the existing refrigerator are fixed without upper and lower limits and front and back limits, the shelves are prone to shaking, resulting in the risk of the shelves falling out during packaging and transportation. In order to prevent the shelves from being damaged by up and down vibration during transportation, an improvement plan is proposed.

[0005] A related art discloses a refrigerator shelf, comprising a storage plate and a limiting assembly. The limiting assembly comprises a clip bar and a locking pin. The clip bar is disposed at the front end of the storage plate, and the locking pins are retractably disposed on either side of the clip bar. A clamping groove is provided at the rear end of the clip bar, into which the front end of the storage plate is inserted, and the clamping groove and the storage plate form an interference fit. A receiving groove is provided on the bottom surface of the clip bar along its length, with a first limiting portion and a second limiting portion provided at each end of the receiving groove. A catch is provided in the middle of the locking pin, which passes through the first and second limiting portions, and the catch is located between the first and second limiting portions.

[0006] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0007] In the prior art, shelves are secured with clips and locking pins, with the locking pins located on either side of the clips. To remove or secure the shelf, users must pull the clips on either side to extend or retract the clips, making it inconvenient. This is especially true when the limiter assembly is located at the rear end of the shelf.

[0008] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0009] The reference to any prior art in the specification is not an acknowledgement or suggestion that the prior art forms part of the common general knowledge in any jurisdiction, or that it could reasonably be expected that the person skilled in the art would understand, consider relevant and / or combine with other prior art.

[0054] For the convenience of describing this embodiment, as shown in FIG1 , the left-right direction is the length direction of the shelf, ie, the first direction, and the front-back direction is as shown in FIG1 .

[0055] 1 to 9 , an embodiment of the present disclosure provides a shelf assembly, which includes: 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 the length direction of the shelf 10, and the guide portion 11 may be a slide groove or a slider; the support member 20 is provided 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 provided at both ends of the support member 20.

[0056] The shelf assembly also includes an operating part 50, which is arranged on the support member 20. The operating part 50 is operable to move along a second direction, which intersects with the first direction, and the second direction is the movement direction of the operating part 50; as the operating part 50 moves, the first telescopic member 30 and the second telescopic member 40 move toward each other along the first direction, so that the first telescopic member 30 and the second telescopic member 40 are retracted into the shelf 10; or as the operating part 50 moves, the first telescopic member 30 and the second telescopic member 40 move away from each other along the first direction, so that the first telescopic member 30 and the second telescopic member 40 are extended out of the shelf 10.

[0057] Optionally, the operating part 50 is movably connected to the support member 20, and the first telescopic member 30 is provided with a first slide 31, which extends obliquely along the length direction of the shelf 10. The second telescopic member 40 is partially nested in the first telescopic member 30, and the second telescopic member 40 is provided with a second slide 41, which is inclined along the length direction of the shelf 10 and is inclined in the same direction as the first slide 31, and the second slide 41 is partially overlapped with the first slide 31. The operating part 50 passes through the first slide 31 and the second slide 41. The movement direction of the operating part 50 intersects with the length direction of the shelf 10. When the operating part 50 moves along the second direction, the first telescopic member 30 and the second telescopic member 40 are simultaneously extended and retracted along the length direction of the shelf 10 driven by the operating part 50.

[0058] According to the embodiment of the present disclosure, a guide portion 11 extending along the length direction of the shelf 10 is provided on the shelf 10, and the first telescopic member 30 and the second telescopic member 40 are both slidably connected to the guide portion 11. Under the 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 be extended or retracted into the shelf 10, wherein the length direction of the shelf 10 is the left and right direction in Figure 1.

[0059] 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 in the left-right direction relative to the support member 20. By providing the second telescopic member 40 and partially nesting the second telescopic member 40 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 in the left-right direction relative to the first telescopic member 30. 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.

[0060] By arranging the movement direction of the operating portion 50 to intersect with the length direction of the shelf 10, that is, the movement direction of the operating portion 50 does not move in the left-right direction. By arranging the first slide 31 on the first telescopic member 30 and the second slide 41 on the second telescopic member 40, and arranging the operating portion 50 to pass through the first slide 31 and the second slide 41, the operating portion 50 can be connected to both the first slide 31 and the second slide 41. In this way, when the operating portion 50 moves, under the limitation of the guide portion 11 of the shelf 10 and the first slide 31 and the second slide 41, the first telescopic member 30 or the second telescopic member 40 will not move in the movement direction of the operating portion 50, and under the limitation of the first slide 31 and the second slide 41, the movement of the operating portion 50 can be converted into movement in the left-right direction, so that the first telescopic member 30 and the second telescopic member 40 simultaneously perform telescopic movement in the left-right direction under the drive 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 or away from each other, so that the first telescopic member 30 and the second telescopic member 40 can be retracted or extended from the shelf 10. When the end of the first slide 31 toward the second slide 41 coincides with the end of the second slide 41 toward the first slide 31, the first telescopic member 30 and the second telescopic member 40 are in the extended position; when the end of the first slide 31 away from the second slide 41 coincides with the end of the second slide 41 away from the first slide 31, the first telescopic member 30 and the second telescopic member 40 are in the 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 the drive of the operating portion 50. Compared with the adjustment method in the related art, 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 extend or retract at the same time, which can effectively improve the convenience of user operation.

[0061] In some embodiments, in combination with what is shown in Figure 1 and Figure 3, the shelf 10 has two slide grooves 11 extending in the left and right directions, and the slide groove 11 includes a first slide groove and a second slide groove, the first slide groove corresponds to the first telescopic member 30, and the first telescopic member 30 is provided with a first slider adapted to the first slide groove, and the second slide groove corresponds to the second telescopic member 40, and the second telescopic member 40 is provided with a second slider adapted to the second slide groove.

[0062] Optionally, a dimension of the first sliding groove along the length direction of the shelf 10 is equal to a distance between a first end of the first slide track 31 and a second end of the first slide track 31 .

[0063] In this way, the first slide groove and the first slider, as well as the operating part 50 and the first slide 31 can be used to jointly limit the moving distance of the first telescopic member 30, thereby preventing the operating part 50 and the first slide 31 from being broken or damaged due to excessive force.

[0064] Optionally, buffer members are provided at both ends of the first sliding groove.

[0065] In this way, by providing the buffer member, the collision between the first telescopic member 30 and the first sliding groove of the shelf 10 can be slowed down, thereby reducing the collision noise.

[0066] Optionally, a dimension of the second sliding 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 .

[0067] In this way, the second slide groove and the second slider, as well as the operating part 50 and the second slide 41 can be used to jointly limit the moving distance of the second telescopic member 40, thereby preventing the operating part 50 and the second slide 41 from being broken or damaged due to excessive force.

[0068] Optionally, buffer members are provided at both ends of the second chute.

[0069] In this way, by providing the buffer member, the collision between the second telescopic member 40 and the second sliding groove of the shelf 10 can be slowed down, thereby reducing the collision noise.

[0070] In some embodiments, the buffer member may be a rubber pad or a silicone pad. It is understood that the specific form of the buffer member is not unique.

[0071] Optionally, the angle between the movement direction of the operating portion 50 , ie, the second direction, and the length direction of the shelf 10 is 90 degrees.

[0072] In this way, by designing the first slideway 31 and the second slideway 41 symmetrically with respect to the operating portion 50 , the first telescopic member 30 and the second telescopic member 40 can move the same distance when the operating portion 50 rotates.

[0073] Optionally, the first telescopic member 30 is a cylindrical structure, the second telescopic member 40 is a cylindrical structure, and the outer wall of the second telescopic member 40 abuts against the inner wall of the first telescopic member 30; wherein, the first slide 31 and the second slide 41 are both spiral, and the spirals of the first slide 31 and the second slide 41 are both less than one circle.

[0074] According to the embodiment of the present disclosure, by configuring the first telescopic member 30 and the second telescopic member 40 as a cylindrical structure, it is not only easier to connect the second telescopic member 40 to the first telescopic member 30, but also possible to reduce the production costs of the first telescopic member 30 and the second telescopic member 40. By abutting the outer wall of the second telescopic member 40 against the inner wall of the first telescopic member 30, the second telescopic member 40 can be embedded in the first telescopic member 30, and the first telescopic member 30 can be used to support the second telescopic member 40, thereby preventing the second telescopic member 40 from increasing movement resistance when connected to the shelf 10.

[0075] By configuring the first slide 31 and the second slide 41 to have a spiral structure with less than one turn, the first telescopic member 30 and the second telescopic member 40 can only move in the left-right direction due to the limitation of the slide groove 11 of the shelf 10. Therefore, the first slide 31 and the second slide 41 can only move in the left-right direction, and the operating portion 50 rotates relative to the first telescopic member 30. By configuring the spiral structure with less than one turn, the first telescopic member 30 and the second telescopic member 40 can be retracted or extended without rotating the operating portion 50 one or more turns, thereby quickly retracting or extending the first telescopic member 30 and the second telescopic member 40, thereby improving user convenience.

[0076] It should be noted that the first telescopic member 30 and the second telescopic member 40 can be a square structure, the first slide 31 is provided on the upper surface of the first telescopic member 30, and the second slide 41 is provided on the upper surface of the second telescopic member 40. It is 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.

[0077] Optionally, an angle between a line connecting the first end of the first slideway 31 and the axis of the first telescopic member 30 and a line connecting the second end of the first slideway 31 and the axis of the first telescopic member 30 is greater than 30 degrees and less than 180 degrees.

[0078] When the angle is less than 30 degrees, the user encounters a large resistance when turning the operating portion 50 , making it difficult for the user to turn the operating portion 50 ; when the angle is greater than 180 degrees, the user encounters a large resistance when turning the operating portion 50 , making it inconvenient for the user to use.

[0079] Optionally, an angle between a line connecting the first end of the second slideway 41 and the axis of the second telescopic member 40 and a line connecting the second end of the second slideway 41 and the axis of the second telescopic member 40 is greater than 30 degrees and less than 180 degrees.

[0080] Thus, when the angle is less than 30 degrees, the user encounters a large resistance to rotating the operating portion 50, making it difficult for the user to rotate the operating portion 50; when the angle is greater than 180 degrees, the angle at which the user rotates the operating portion 50 is too large, making it inconvenient for the user to use.

[0081] Optionally, the angle between the first line and the second line is 90 degrees, the first line is the line connecting the first end of the first slide 31 and the axis of the first telescopic member 30, and the second line is the line connecting the second end of the first slide 31 and the axis of the first telescopic member 30; and the angle between the third line and the fourth line is 90 degrees, the third line is the line connecting the first end of the second slide 41 and the axis of the second telescopic member 40, and the fourth line is the line connecting the second end of the second slide 41 and the axis of the second telescopic member 40.

[0082] In this way, not only can the problem of the angle being too small causing the user to have a large resistance to rotation and being difficult to rotate be avoided, but also the problem of the angle being too large causing the user to have a large rotation angle and being difficult for the user to operate be avoided.

[0083] Optionally, the shelf assembly also includes: a first elastic member 60, the first elastic member 60 is arranged in the first telescopic member 30, one end of the first elastic member 60 is connected to the first telescopic member 30, and the other 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.

[0084] According to the embodiment 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, the first elastic member 60 can cause the second telescopic member 40 to move away from the first telescopic member 30. In this way, the first elastic member 60 can automatically extend the first telescopic member 30 and the second telescopic member 40. 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, the first elastic member 60 can drive the second telescopic member 40 and the first telescopic member 30 to move to the extended position, ensuring that the second telescopic member 40 and the first telescopic member 30 are always in the extended position, avoiding the first telescopic member 30 and the second telescopic member 40 from shrinking due to other reasons such as vibration, which may 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, when the second telescopic member 40 is in the retracted position, the compression amount of the first elastic member 60 reaches the maximum, which can prevent the user from rotating the operating part 50 too fast, causing the operating part 50 to collide with the end of the corresponding slide groove 11, resulting in damage or breakage.

[0085] It should be noted that the first elastic member 60 may be a spring, a polyurethane elastomer, a rubber elastomer, etc. It is understandable that the specific form of the first elastic member 60 is not unique.

[0086] Optionally, the support member 20 includes a support seat 21 , a mounting opening 211 is defined in the middle of the support seat 21 , and the mounting opening 211 is adapted to fit the first telescopic member 30 so that the support seat 21 is nested in the first telescopic member 30 .

[0087] According to the embodiment of the present disclosure, by providing a support seat 21 and defining a mounting opening 211 adapted to the first telescopic member 30 in the middle of the support member 20, the first telescopic member 30 can be extended into the support seat 21 along the mounting opening 211, so that the support seat 21 is nested with the first telescopic member 30, supporting the first telescopic member 30.

[0088] In some embodiments, the installation opening 211 is extended in the left-right direction, so that the first telescopic member 30 can extend into the support base 21 in the left-right direction relative to the support base 21 .

[0089] Optionally, the support member 20 is provided on the upper end surface of the shelf 10 and is located at the rear of the shelf 10 .

[0090] Thus, by arranging the support member 20 at the rear of the shelf 10, the first telescopic member 30 and the second telescopic member 40 are also arranged at the rear of the shelf 10, thereby preventing the first telescopic member 30 and the second telescopic member 40 from blocking the user from placing items, thereby ensuring the convenience of the user in placing items on the shelf 10. In addition, compared with the arrangement in the related art, when the device in the related art is arranged at the rear of the shelf 10, it is very inconvenient for the user to operate. The arrangement position of this embodiment makes it easier for the user to operate the operating portion 50 connected to the support member 20, thereby improving user convenience.

[0091] Optionally, the support member 20 is provided at the front end of the shelf 10 .

[0092] In this way, it is convenient for the user to operate the operating portion 50, thereby improving the convenience of the user in using the shelf assembly.

[0093] Optionally, a first track 212 and a second track are respectively provided on both sides of the support seat 21, and the first track 212 and the second track are both extended along the wall surface of the first telescopic member 30; the support member 20 also includes: a connecting frame 22, which defines a through hole 221, and the through hole 221 is adapted to the operating part, and is slidably connected to the first track 212 and the second track, so that the operating part is slidably connected to the support seat 21.

[0094] According to the embodiment of the present disclosure, by providing a first track 212 and a 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 along the first track 212 and the second track relative to the support base 21. By providing 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. By providing a through hole 221 in the connecting frame 22 that is compatible with the operating portion 50, the operating portion 50 can be connected to the connecting frame 22, so that the operating portion 50 is driven by the connecting frame 22 to slide relative to the support base 21.

[0095] In some embodiments, the support seat 21 includes a first support and a second support, and the first support and the second support are spaced apart along the length direction of the shelf 10. The first support and the second support form a gap, and the gap is set corresponding to the through hole 221. The width of the gap is adapted to the operating part 50 so that the operating part 50 passes through the gap and is connected to the first slide groove 31 and the second slide groove 41.

[0096] In this way, it is easy to position and install the first telescopic member 30 and the support base 21, thereby improving the convenience of installation for users.

[0097] Optionally, the middle protrusion of the operating part 50 forms a snap-fitting part 51, and the connecting frame 22 is provided with a snap-fitting space 222 having a snap-fitting interface, the snap-fitting space 222 is communicated with the through hole 221, and the snap-fitting interface is adapted to the snap-fitting part 51; wherein, when the snap-fitting part 51 is located in the snap-fitting space 222, the operating part has a first position and a second position, and the operating part 50 can rotate between the first position and the second position, and when the operating part 50 is located in the second position, the operating part 50 is fixedly connected to the connecting frame 22.

[0098] In the disclosed embodiment, by providing a snap-fit ​​portion 51 on the operating portion 50 and a snap-fit ​​space 222 on the connecting frame 22, the operating portion 50 can be snap-fitted to the connecting frame 22. The operating portion 50 can be inserted through the connecting frame 22 through the through-hole 221 until the snap-fit ​​portion 51 moves from the snap-fit ​​interface into the snap-fit ​​space 222. The operating portion 50 can then be fixed to the connecting frame 22 by rotating it. This not only ensures a secure connection between the operating portion 50 and the connecting frame 22, but also facilitates removal of the operating portion 50 from the connecting frame 22, making it easier for the user to repair or replace the operating portion 50.

[0099] Optionally, the snap-fit ​​space 222 includes a first accommodating cavity 2221 and a second accommodating cavity 2222, and the first accommodating cavity 2221 is connected to the second accommodating cavity 2222. When the operating part 50 is in the first position, the snap-fit ​​portion 51 is located in the first accommodating cavity 2221, and when the operating part 50 is in the second position, the snap-fit ​​portion 51 is located in the second accommodating cavity 2222, wherein the second distance between the upper wall and the lower wall of the second accommodating cavity 2222 is smaller than the first distance between the upper wall and the lower wall of the first accommodating cavity 2221.

[0100] In this way, by setting the second distance of the second accommodating cavity 2222 to be smaller than the first distance of the first accommodating cavity 2221, when the clamping part 51 is rotated to the second position, the friction resistance between the wall of the clamping space 222 and the clamping part 51 can be increased, thereby preventing the clamping part 51 from detaching from the second accommodating cavity 2222, and ensuring the connection reliability between the operating part 50 and the connecting frame 22.

[0101] Optionally, the clamping portion 51 includes an upper wall surface and a lower wall surface, and the distance between the upper wall surface and the lower wall surface is gradually reduced in a direction toward the operating portion.

[0102] In this way, the contact area between the clamping portion 51 and the clamping space 222 can be increased, thereby increasing the friction resistance and further improving the connection reliability between the operating portion 50 and the connecting frame 22 .

[0103] In some embodiments, as shown in FIG. 4 , the clamping portion 51 is a fan-shaped structure, and there are two clamping portions 51 . The two clamping portions 51 are evenly spaced apart and arranged on the operating portion 50 .

[0104] In this way, the connection stability between the operating portion 50 and the connecting frame 22 can be ensured.

[0105] Optionally, the first slide 31 includes a first slide section 311 and a second slide section 312, the first slide section 311 is located at the end of the first slide 31 facing the second telescopic member 40, and the second slide section 312 is connected to the first slide section 311, wherein the helix angle of the first slide section 311 is smaller than the helix angle of the second slide section 312.

[0106] In this way, since the interior of the refrigeration equipment is in a low-temperature environment for a long time, due to the effect of condensation, the internal items will have a certain adhesion force, making it difficult to move. By setting the spiral angle of the first slide section 311 to be smaller than the spiral angle of the second slide section 312, when the operating portion 50 moves along the first slide section 311, the distance moved by the first telescopic member 30 is smaller than when the operating portion 50 slides along the second slide section 312 when the operating portion 50 rotates the same angle, that is, the contraction distance of the first telescopic member 30 is shorter. When the user starts to rotate the operating portion 50, the first telescopic member 30 can have a large acceleration, and the user can use less force to drive the first telescopic member 30 to expand and contract, thereby improving the user's operational convenience. In addition, when the first telescopic member 30 is extended, when the operating part 50 moves from the second slide section 312 to the first slide section 311, the extension speed of the first telescopic member 30 can be slowed down, 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 part 50 too fast, or the first elastic member 60 drives the first telescopic member 30 to automatically extend too fast, and the operating part 50 hits the end of the first slide 31, causing the operating part 50 to break or the first slide 31 to be damaged.

[0107] Optionally, the first slide 31 also includes: a third slide section 313, the third slide section 313 is located at the end of the first slide 31 away from the second telescopic member 40, the third slide section 313 is connected to the second slide section 312, wherein the helix angle of the third slide section 313 is smaller than the helix angle of the second slide section 312.

[0108] 312, operating part 50 is provided with the first telescopic member 30 of the embodiment of the present invention.Like this, by the helical angle of the 3rd sliding section 313 being less than the helical angle of the second sliding section 312 being provided, when operating part 50 moves along the 3rd sliding section 313, compared to operating part 50 sliding along the second sliding section 312, the distance that operating part 50 rotates the same angle first telescopic member 30 and moves is littler, that is to say, the moving distance of first telescopic member 30 is shorter.When first telescopic member 30 is shrinking, can slow down the contraction speed of first telescopic member 30, remind the user first telescopic member 30 and be about to arrive the retracted position, avoid following problem to occur: user rotates operating part 50 too fast, operating part 50 hits the end of the first slideway 31, causes operating part 50 fractures or the first slideway 31 damage.When first telescopic member 30 is stretching out, can make first telescopic member 30 have bigger acceleration, be convenient to drive first telescopic member 30 motions, even when the driving force of first elastic member 60 constantly reduces, also can make operating part 50 slide to first sliding section 311 under the effect of the elastic force of the first elastic member 60, make first telescopic member 30 stretch out enough distances.

[0109] Optionally, the second slide 41 includes a fourth slide section 411 and a fifth slide section 412, the fourth slide section 411 is located at the end of the second slide 41 facing the first telescopic member 30, and the fourth slide section 411 is connected to the fifth slide section 412, wherein the helix angle of the fourth slide section 411 is smaller than the helix angle of the fifth slide section 412.

[0110] In this way, since the interior of the refrigeration equipment is in a low-temperature environment for a long time, due to the effect of condensation, the internal items will have a certain adhesion force, making it difficult to move. By setting the spiral angle of the fourth slide 411 to be smaller than the spiral angle of the fifth slide 412, when the operating part 50 moves along the fourth slide 411, compared to when the operating part 50 slides along the fifth slide 412, the distance moved by the second telescopic member 40 when the operating part 50 rotates the same angle is smaller, that is, the contraction distance of the second telescopic member 40 is shorter. When the user starts to rotate the operating part 50, the second telescopic member 40 can have a larger acceleration, and the user can use less force to drive the second telescopic member 40 to expand and contract, thereby improving the user's operational convenience. In addition, when the second telescopic member 40 is extended, when the operating part 50 moves from the fifth slide section 412 to the fourth slide section 411, the extension speed of the second telescopic member 40 can be slowed down, 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 part 50 too fast, or the first elastic member 60 drives the second telescopic member 40 to automatically extend too fast, and the operating part 50 hits the end of the second slide 41, causing the operating part 50 to break or the second slide 41 to be damaged.

[0111] Optionally, the second slide 41 also includes: a sixth slide section 413, the sixth slide section 413 is located at the end of the second slide 41 away from the first telescopic member 30, the sixth slide section 413 is connected to the fifth slide section 412, wherein the helix angle of the sixth slide section 413 is smaller than the helix angle of the fifth slide section 412.

[0112] 412, and second telescopic member 40 is stretched out.When second telescopic member 40 is stretched out, second telescopic member 40 is stretched out, and second telescopic member 40 is stretched out.When second telescopic member 40 is stretched out, second telescopic member 40 is stretched out, and second telescopic member 40 is stretched out.When second telescopic member 40 is stretched out, second telescopic member 40 is stretched out, and second telescopic member 40 is stretched out.When second telescopic member 40 is stretched out, second telescopic member 40 is stretched out, and second telescopic member 40 is stretched out.When second telescopic member 40 is stretched out, second telescopic member 40 is stretched out, and second telescopic member 40 is stretched out.

[0113] 10 to 16 , an embodiment of the present disclosure provides another shelf assembly for refrigeration equipment, the shelf assembly for refrigeration equipment comprising: a shelf 10, a support member 20, a first telescopic member 30 and a second telescopic member 40, the shelf 10 being provided with a guide portion 11, the guide portion 11 being one of a slide rail or a slider, the guide portion 11 or the sliding portion 12 extending along the length direction of the shelf 10; the support member 20 being provided on the shelf 10; the first telescopic member 30 being movably connected to the support member 20 and the first telescopic member 30 being slidably connected to the guide portion 11; the second telescopic member 40 being slidably connected to the guide portion 11, and along the first direction, the first telescopic member 30 and the second telescopic member 40 being respectively provided at both ends of the support member 20.

[0114] The shelf assembly also includes an operating part 50, which is arranged on the support part 20. The operating part 50 is operable to move along a second direction, which intersects with the first direction. The second direction is the movement direction of the operating part 50. The first telescopic part 30 and the second telescopic part 40 move toward each other along the first direction as the operating part 50 moves, so that the first telescopic part 30 and the second telescopic part 40 are retracted into the shelf 10; or the first telescopic part 30 and the second telescopic part 40 move away from each other along the first direction as the operating part 50 moves, so that the first telescopic part 30 and the second telescopic part 40 are extended out of the shelf 10.

[0115] The support member 20 is configured as a shaft cylinder, which is extended along the length direction of the shelf 10 and is rotatably connected to the shelf 10 . The shaft cylinder is provided with a slide groove 121, which is spiral; the first telescopic member 30 and the second telescopic member 40 are respectively nested in the shaft cylinder, and the first telescopic member 30 and the second telescopic member 40 are respectively slidably connected with the slide groove 121 of the shaft cylinder, and the first telescopic member 30 and the second telescopic member 40 are provided with a sliding portion 12, which can be another one of a slide rail or a slider, and the sliding portion 12 is adapted to the guide portion 11 so that the first telescopic member 30 and the second telescopic member 40 are slidably connected with the shelf 10; wherein the first telescopic member 30 and the second telescopic member 40 are respectively provided at both ends of the shaft cylinder, and the number of the slide groove 121 and the guide portion 11 are both two and are respectively provided with the first telescopic member 30 and the second telescopic member 40. When the shaft cylinder rotates, it drives the first telescopic member 30 and the second telescopic member 40 to extend and retract along the extension direction of the shaft cylinder, so that the first telescopic member 30 and the second telescopic member 40 extend out of the shelf 10 or retract the shelf 10.

[0116] With the shelf assembly for refrigeration equipment according to the embodiment of the present disclosure, by providing one of a slide rail or a slider on the shelf 10, and providing a slider adapted to the slide rail or a slide rail adapted to the slider on the first telescopic member 30 and the second telescopic member 40, the first telescopic member 30 and the second telescopic member 40 can be slidably connected to the shelf 10, and the first telescopic member 30 and the second telescopic member 40 can slide along the length direction of the shelf 10. The length direction of the shelf 10 is the left-right direction in FIG.

[0117] By providing a shaft cylinder and rotatably connecting the shaft cylinder, the shelf 10 can support the shaft cylinder and the shaft cylinder can rotate relative to the shelf 10. By providing a spiral groove 121 on the shaft cylinder and slidingly connecting the first telescopic member 30 and the second telescopic member 40 to the groove 121, when the user rotates the shaft cylinder, the first telescopic member 30 and the second telescopic member 40 are driven by the groove 121 and limited by the guide portion 11 to extend and retract along the extension direction of the shaft cylinder.

[0118] By providing the first telescopic member 30 and the second telescopic member 40 at both ends of the shaft cylinder and providing two slide grooves 121 on the shaft cylinder, the first telescopic member 30 and the second telescopic member 40 can be driven to perform telescopic movements simultaneously when the shaft cylinder rotates. In other words, the first telescopic member 30 and the second telescopic member 40 can be moved toward or away from each other when the shaft cylinder rotates, so that the first telescopic member 30 and the second telescopic member 40 can be retracted or extended from the shelf 10. Compared with the adjustment method in the related art, this embodiment can extend or retract the first telescopic member 30 and the second telescopic member 40 on both sides by simply rotating the shaft cylinder, which can effectively improve the convenience of user operation.

[0119] In some embodiments, as shown in Figures 10 and 11, the spiral direction of the slide groove 121 is set in a clockwise direction. When the user rotates the shaft cylinder in the forward direction, the first telescopic member 30 and the second telescopic member 40 can be retracted. When the user rotates the shaft cylinder in the reverse direction, the first telescopic member 30 and the second telescopic member 40 can be extended.

[0120] Optionally, the shaft cylinder is arranged at the front end of the shelf 10 .

[0121] In this way, it is easy for users to operate the shaft cylinder, thereby improving the convenience of user operation.

[0122] Optionally, the shaft cylinder is arranged at the rear of the shelf 10 .

[0123] In this way, by setting the shaft tube at the rear of the shelf 10, the first telescopic member 30 and the second telescopic member 40 are also set at the rear of the shelf 10, which can reduce the space occupied by the shelf 10, avoid the first telescopic member 30 and the second telescopic member 40 blocking the user from placing items, and improve the convenience of user use.

[0124] Optionally, the shelf assembly also includes: a sleeve 131, a fixing seat 32 and a connecting rod 33, one end of the sleeve 131 is arranged in the shaft cylinder and is slidably connected to the shaft cylinder, the other end of the sleeve 131 extends in the direction away from the shaft cylinder, and the outer wall of the other end of the sleeve 131 is provided with a sliding portion 12; the fixing seat 32 is arranged in the sleeve 131; the connecting rod 33 is arranged in the fixing seat 32 and extends to the outside of the sleeve 131 and is located in 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, and by rotating the shaft cylinder, the two sleeves 131 move between the extended position and the retracted position along the extension direction of the shaft cylinder, so that the sleeve 131 extends out of the shelf 10 or retracts the shelf 10.

[0125] The shelf assembly for refrigeration equipment according to the embodiment of the present disclosure is adopted. By arranging a sliding portion 12 on the sleeve 131 and arranging a guide portion 11 compatible with the sliding portion 12 on the shelf 10, the guide portion 11 can not only make the sleeve 131 slidably connected to the shelf 10, but also prevent the sleeve 131 from rotating relative to the shaft cylinder, thereby making the sleeve 131 rotatably connected to the shaft cylinder, and the rotation of the shaft cylinder will not drive the sleeve 131 to rotate.

[0126] By setting a 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. In this way, when the shaft cylinder rotates, the connecting rod 33 moves along the extension direction of the shaft cylinder under the 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 out of the shelf 10 and is suitable for connecting to the refrigeration equipment or retracting the shelf 10 to disconnect from the refrigeration equipment.

[0127] Optionally, the spiral of the slide groove 121 is less than one turn, and the angle between the two connecting lines is greater than 30 degrees and less than 180 degrees, where one connecting line is the line connecting the first end of the slide groove 121 and the axis of the shaft cylinder, and the other connecting line is the line connecting the second end of the slide groove 121 and the axis of the shaft cylinder.

[0128] The shelf assembly for refrigeration equipment using the embodiment of the present disclosure is configured such that the spiral of the slide groove 121 is less than one turn. In this way, the sleeve 131 can be quickly retracted or extended without rotating the shaft cylinder one or more times, thereby improving the convenience of user operation. By configuring the angle between the two connecting lines to be greater than 30 degrees and less than 180 degrees, when the angle is less than 30 degrees, the user faces greater resistance to rotating the shaft cylinder, making it difficult for the user to rotate the shaft cylinder; and when the angle is greater than 180 degrees, the angle at which the user rotates the shaft cylinder is too large, making it inconvenient for the user to rotate the shaft cylinder.

[0129] Preferably, the angle between the two connecting lines is 90 degrees, wherein one connecting line is a line connecting the first end of the slide groove 121 and the axis of the shaft cylinder, and the other connecting line is a line connecting the second end of the slide groove 121 and the axis of the shaft cylinder.

[0130] In this way, not only can the problem of the angle being too small causing the user to have a large resistance to rotation and being difficult to rotate be avoided, but also the problem of the angle being too large causing the user to have a large rotation angle and being difficult for the user to operate be avoided.

[0131] Optionally, the length of the guide portion 11 is equal to the distance between the first end of the sliding groove 121 and the second end of the sliding groove 121 .

[0132] In this way, the guide portion 11 and the sliding portion 12 as well as the connecting rod 33 and the sliding groove 121 can be used to jointly limit the moving distance of the sleeve 131, thereby preventing the connecting rod 33 and the sliding groove 121 from being broken or damaged due to excessive force.

[0133] Optionally, buffer members are provided at both ends of the guide portion 11 .

[0134] In this way, by providing the buffer member, the impact force between the sleeve 131 and the guide portion 11 or the sliding portion 12 of the shelf 10 can be reduced, thereby reducing the impact noise.

[0135] In some embodiments, the buffer member may be a rubber pad or a silicone pad. It is understood that the specific form of the buffer member is not unique.

[0136] Optionally, the shelf assembly for the refrigeration equipment also includes: a second elastic member 140, the second elastic member 140 is arranged in the shaft cylinder, one end of the second elastic member 140 is connected to the shaft cylinder, and the other end of the second elastic member 140 is connected to the sleeve 131; wherein, when the sleeve 131 moves toward the shaft cylinder, the second elastic member 140 is compressed.

[0137] In the shelf assembly for refrigeration equipment of the present disclosure, by providing a second elastic member 140, the second elastic member 140 can drive the sleeve 131 to move away from the shaft barrel. In other words, the second elastic member 140 can cause the sleeve 131 to extend out of the shaft barrel. In this way, the second elastic member 140 can automatically extend the sleeve 131 out of the shaft barrel. By configuring the second elastic member 140 to be compressed when the sleeve 131 moves toward the shaft barrel, the second elastic member 140 can drive the sleeve 131 to the extended position, ensuring that the sleeve 131 is always in the extended position, thereby preventing the sleeve 131 from contracting due to vibration or other reasons, thereby preventing the shelf 10 from being fixed. Furthermore, by configuring the second elastic member 140 to be compressed when the sleeve 131 moves toward the shaft barrel, that is, when the sleeve 131 is in the retracted position, the second elastic member 140 reaches its maximum compression, thereby preventing the user from rotating the operating portion 50 too quickly, causing the connecting rod 33 to collide with the end of the slide slot 121, resulting in damage or breakage.

[0138] In some embodiments, a support wall is provided in the shaft cylinder, and the support wall blocks the shaft cylinder. The second elastic member 140 is a spring, one end of the spring is connected to the support wall, and the other end of the spring is connected to the sleeve 131 .

[0139] In this way, when the shaft cylinder is not subjected to external force, it can move in a direction away from the shaft cylinder under the action of the spring until the shaft cylinder moves to the extended position, thereby realizing automatic extension of the shaft cylinder.

[0140] It should be noted that the second elastic member 140 may also be a polyurethane elastomer, a rubber elastomer, etc. It is understandable that the specific form of the second elastic member 140 is not unique.

[0141] Optionally, the connecting rod 33 is telescopically connected to the fixing seat 32 , and the connecting rod 33 can extend out of the sleeve 131 or retract into the sleeve 131 to facilitate connecting the first telescopic member 30 and the second telescopic member 40 .

[0142] When the shelf assembly for refrigeration equipment is used in the embodiment of the present disclosure, when the first telescopic member 30 and the second telescopic member 40 are connected to the shaft cylinder, the connecting rod 33 is retracted into the interior of the sleeve 131. When the sleeve 131 is installed in place, the connecting rod 33 extends out and extends into the slide groove 121, which can improve the reliability of the connection between the telescopic assembly 30 and the shaft cylinder.

[0143] In some embodiments, as shown in Figures 12 and 15, a through hole is opened at the bottom of the fixing seat 32, and the through hole is adapted to the bottom of the connecting rod 33. The middle part of the connecting rod 33 bulges outward to form an abutment portion 332. The spring is nested in the connecting rod 33, and one end of the spring is connected to the abutment portion 332, and the other end of the spring is connected to the fixing seat 32.

[0144] In this way, the connecting rod 33 and the fixing seat 32 can be telescopically connected, which not only reduces the cost but also ensures the reliability of the connection.

[0145] Optionally, the shelf assembly for refrigeration equipment further includes a motor, which is disposed in the shaft cylinder and drivingly connected to the connecting rod 33 , for driving the connecting rod 33 to extend or retract into the sleeve 131 .

[0146] In this way, the connecting rod 33 and the fixing seat 32 can be automatically telescopically connected, and the motor can drive the connecting rod 33 to automatically extend or retract into the sleeve 131.

[0147] It should be noted that the specific form of the telescopic connection between the connecting rod 33 and the fixing seat 32 is not unique.

[0148] Optionally, the inner wall of the shaft cylinder is partially recessed to provide a mounting groove 122 , which extends along the extension direction of the shaft cylinder to the slide groove 121 . The mounting groove 122 is adapted to the connecting rod 33 to facilitate installation of the sleeve 131 and the shaft cylinder.

[0149] The shelf assembly for refrigeration equipment according to the embodiment of the present disclosure is adopted, by setting a mounting groove 122 on the inner wall surface of the shaft cylinder and matching the mounting groove 122 with the connecting rod 33. On the one hand, the mounting groove 122 can accommodate the connecting rod 33, and on the other hand, the mounting groove 122 and the connecting rod 33 can limit the angle between the shaft cylinder and the sleeve 131 during the installation process, thereby improving the installation convenience of the sleeve 131 and the shaft cylinder.

[0150] Optionally, a mounting slope 23 is provided at the connection between the slide groove 121 and the mounting groove 122 to facilitate the installation of the connecting rod 33 and the slide groove 121 .

[0151] The shelf assembly for refrigeration equipment adopts the embodiment of the present disclosure, and a mounting bevel 23 is provided at the connection between the slide groove 121 and the mounting groove 122. The mounting bevel 23 is tilted upward along the contraction direction of the sleeve 131. When the sleeve 131 is installed into the shaft cylinder, the connecting rod 33 can extend out of the slide groove 121 along the mounting bevel 23, thereby improving the installation convenience of the sleeve 131 and the shaft cylinder.

[0152] Optionally, an anti-slip structure 331 is provided at the top end of the connecting rod 33 , and the anti-slip structure 331 is protruded along the circumference of the connecting rod 33 .

[0153] In this way, by setting an anti-slip structure 331 at the top of the connecting rod 33, the anti-slip structure 331 is set to protrude along the circumference of the connecting rod 33, which can prevent the connecting rod 33 from escaping from the sliding groove 121 and improve the stability of the connection between the connecting rod 33 and the sliding groove 121.

[0154] Optionally, the abutting portion 332 is adapted to the size of the fixing seat 32 so that the wall surface of the abutting portion 332 abuts against the inner side wall of the fixing seat 32 .

[0155] In this way, when the connecting rod 33 is located in the fixed seat 32, under the limitation of the abutment portion 332 and the fixed seat 32, the connecting rod 33 can only move relative to the fixed seat 32 in the up and down directions, which can avoid the direction of the connecting rod 33 extending out after compression being unfixed, thereby improving the convenience of connecting the connecting rod 33 with the slide groove 121.

[0156] Optionally, the opening area of ​​the end portion of the mounting groove 122 away from the shaft cylinder is gradually reduced along the direction in which the sleeve 131 contracts.

[0157] In this way, by gradually reducing the opening area of ​​the end of the mounting groove 122 away from the shaft cylinder along the direction of contraction of the sleeve 131, when the telescopic assembly 30 is connected to the shaft cylinder, the connecting rod 33 can be compressed by the end of the mounting groove 122, making it easier for the connecting rod 33 to extend into the fixed seat 32, so as to facilitate the extension of the telescopic assembly 30 into the shaft cylinder, thereby improving the convenience of connecting the telescopic assembly 30 with the shaft cylinder.

[0158] Optionally, the shelf assembly for refrigeration equipment further includes an operating portion 50 , which is provided on the outer wall surface of the shaft cylinder to facilitate the rotation of the shaft cylinder.

[0159] The shelf assembly for refrigeration equipment using the disclosed embodiment of the present invention is provided with an operating portion 50 disposed on the outer wall of the shaft cylinder. The operating portion 50 can be configured as a handle or as the outer wall of the shaft cylinder. The user can rotate the shaft cylinder by turning the handle. Compared with directly rotating the shaft cylinder, this is more convenient for the user, reduces the difficulty of the user's operation, and can cause the shaft cylinder to rotate with less force.

[0160] In some embodiments, the operating portion 50 is disposed in the middle of the shaft tube and corresponds to the second end of the sliding groove 121 .

[0161] In this way, by arranging the operating part 50 in the middle of the shaft tube and arranging the operating part 50 corresponding to the second end of the slide groove 121, the force acting on the operating part 50 can be evenly applied to both sides of the shaft tube, ensuring that the force on the shaft tube is uniform and improving the reliability of the device.

[0162] Optionally, the operating portion 50 is a flat plate structure and is extended along the extension direction of the shaft tube. The length of the operating portion 50 is slightly smaller than the distance between the two sliding grooves 121 .

[0163] In this way, the grippable area of ​​the operating portion 50 can be increased, further improving the convenience of user operation.

[0164] It should be noted that the operating portion 50 may also be a cylindrical structure. 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.

[0165] Optionally, the shelf assembly for the refrigeration equipment further includes: a bracket 160, which is arranged on the shelf 10, and there are two brackets 160. The two brackets 160 are respectively arranged on both sides of the shaft cylinder and are both rotatably connected to the shaft cylinder.

[0166] The shelf assembly for refrigeration equipment according to the embodiment of the present disclosure is used to ensure that the shaft cylinder and the shelf 10 are firmly connected by providing a bracket 160. By providing two brackets 160 and arranging the two brackets 160 on both sides of the shaft cylinder, the brackets 160 can support both sides of the shaft cylinder, thereby keeping the shaft cylinder stable.

[0167] In some embodiments, the bracket 160 is a support plate that defines a mounting opening, and the mounting opening is adapted to the shaft tube so that the bracket 160 is sleeved on the shaft tube and the two are rotatably connected.

[0168] In this way, the shaft cylinder can be installed in the installation opening so that the shaft cylinder and the bracket 160 are rotatably connected.

[0169] Optionally, the slide groove 121 includes a first groove section 1211 and a second groove section 1212, the first groove section 1211 is located at the end of the slide groove 121 facing the sleeve 131, and the second groove section 1212 is connected to the first groove section 1211, wherein the helix angle of the first groove section 1211 is smaller than the helix angle of the second groove section 1212.

[0170] In this way, since the interior of the refrigeration equipment is in a low-temperature environment for a long time, due to the effect of condensation, the internal items will have a certain degree of adhesion, making it difficult to move. By setting the spiral angle of the first groove section 1211 to be smaller than the spiral angle of the second groove section 1212, when the connecting rod 33 moves along the first groove section 1211, the distance the connecting rod 33 moves when the operating part 50 rotates the same angle is smaller than when the connecting rod 33 slides along the second groove section 1212. In other words, the contraction distance of the sleeve 131 is shorter. When the user first rotates the operating part 50, the sleeve 131 can have a larger acceleration. The user can use less force to drive the sleeve 131 to retract and retract, thereby improving the user's operating convenience. In addition, when the sleeve 131 is extended, when the connecting rod 33 moves from the second slot section 1212 to the first slot section 1211, the extension speed of the sleeve 131 can be slowed down, reminding the user that the sleeve 131 is about to reach the extended position, avoiding the user turning the operating part 50 too quickly or the second elastic member 140 driving the sleeve 131 to automatically extend too quickly, causing the connecting rod 33 to hit the end of the slide groove 121, resulting in the connecting rod 33 breaking or the slide groove 121 being damaged.

[0171] Optionally, the slide groove 121 also includes: a third groove section 1213, the third groove section 1213 is located at the end of the slide groove 121 away from the sleeve 131, the third groove section 1213 is connected to the second groove section 1212, wherein the helix angle of the third groove section 1213 is smaller than the helix angle of the second groove section 1212.

[0172] Thus, by setting the helical angle of the third slot section 1213 smaller than the helical angle of the second slot section 1212, when the connecting rod 33 moves along the third slot section 1213, the distance the connecting rod 33 moves is smaller than when the operating portion 50 rotates the same angle along the second slot section 1212. In other words, the distance the sleeve 131 moves is shorter. When the sleeve 131 retracts, the retraction speed of the sleeve 131 can be slowed down, alerting the user that the retracted position is about to be reached, and preventing the user from rotating the operating portion 50 too quickly, causing the connecting rod 33 to strike the end of the chute 121, thereby breaking the connecting rod 33 or damaging the chute 121. When the sleeve 131 extends, the sleeve 131 can have a greater acceleration, which facilitates the movement of the sleeve 131. Even if the driving force of the second elastic member 140 continues to decrease, the elastic force of the second elastic member 140 can still cause the connecting rod 33 to slide to the first slot section 1211, allowing the sleeve 131 to extend a sufficient distance.

[0173] Optionally, the barrel is made of a transparent material.

[0174] In this way, by making the shaft tube from a transparent material, the user can clearly see the relative position of the connecting rod 33 and the slide groove 121, and then intuitively judge whether the sleeve 131 is in the extended position or the retracted position, avoiding the situation where the user cannot intuitively see the position of the connecting rod 33 relative to the slide groove 121 and make an erroneous operation.

[0175] An embodiment of the present disclosure provides a refrigeration device, which includes a shelf assembly as described in any one of the above optional embodiments.

[0176] The refrigeration equipment using the embodiment of the present disclosure includes the shelf assembly of any of the above embodiments, and therefore has the beneficial effects of the shelf assembly of any of the above embodiments, which will not be described in detail here.

[0178] In this way, by providing support ribs 71 on the inner container 70, the support ribs 71 can support the shelf 10. By providing fixing holes and matching the fixing holes with the first telescopic member 30 or the second telescopic member 40, when the first telescopic member 30 or the second telescopic member 40 extends out of the shelf 10, the first telescopic member 30 or the second telescopic member 40 extends into the fixing hole of the corresponding side wall, thereby defining the position of the shelf 10 and further defining the position of the shelf 10 relative to the inner container 70.

[0179] Optionally, the number of the support ribs 71 and the number of the fixing holes are both multiple, the number of the fixing holes is the same as the number of the support ribs 71 , and the multiple support ribs 71 and the multiple fixing holes are spaced apart along the height direction of the inner liner 70 .

[0180] In this way, the shelf 10 can be connected to any one of the multiple support ribs 71 to flexibly adjust the height position of the shelf 10 in the inner pot 70, and the shelf 10 can be connected to the fixing hole through the first telescopic member 30 and the second telescopic member 40 to limit the position of the shelf 10 relative to the inner pot 70.

[0181] It should be noted that the refrigeration equipment can also be equipment such as freezers and wine cabinets. It can be understood that the refrigeration equipment includes but is not limited to refrigerators, freezers and wine cabinets.
