Description

Technical Field

[0001] This application relates to the technical field of household appliances, for example, to a shelf and a refrigeration device. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature and is also a civilian product that keeps food or other items in a constant low temperature state. A refrigerator is one of the necessities of family life in modern society. Especially in summer, in order to ensure that food does not spoil in a short time, the food needs to be placed in the refrigerator for storage. In order to meet the user's need to store items, a shelf for holding items is provided in the storage compartment of the refrigerator.

[0003] Currently, the shelf in the storage compartment of a refrigerator is generally supported and fixed by the rib on the inner surface of the inner liner. Due to the lack of upper and lower limits and front and rear limits of the shelf in the existing fixing method of the refrigerator shelf, the shelf is prone to shaking, resulting in the risk of the shelf coming out and falling during packaging and transportation. In order to avoid damage caused by the up and down vibration of the shelf during transportation, an improvement scheme is proposed for it.

[0004] A related technology discloses a refrigerator shelf. The refrigerator shelf includes a placement board and a limiting component. The limiting component includes a clamping strip and a locking pin. The clamping strip is arranged at the front end of the placement board, and the locking pin is telescopically arranged on both sides of the clamping strip. A clamping groove is provided at the rear end of the clamping strip, and the front end of the placement board is inserted into the clamping groove, and the clamping groove and the placement board are in interference fit. A receiving groove is provided on the bottom surface of the clamping strip along the length direction of the clamping strip, and a first limiting portion and a second limiting portion are provided at both ends of the receiving groove; a handle is provided in the middle of the locking pin, and the locking pin passes through the first limiting portion and the second limiting portion, and the handle is located between the first limiting portion and the second limiting portion.

[0005] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related technology:

[0006] In the related technology, the shelf is fixed by a clamping strip and a locking pin. The locking pins are arranged on both sides of the clamping strip. When the user disassembles or fixes the shelf, the user needs to respectively pull the handles on both sides to make the clamping strip extend or contract, which is not convenient to use. Especially when the limiting component is arranged at the rear end of the shelf, it is even more inconvenient for the user.

[0007] It should be noted that the information disclosed in the above background art section is only used to strengthen the understanding of the background of this application, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0048] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other.

[0049] For the convenience of describing this embodiment, as Figure 1 shown in the figure, the left-right direction is the length direction of the shelf, and the front-back direction is as Figure 1 shown in the figure.

[0050] Combined with Figures 1 to 9 shown in the figure, the embodiment of the present disclosure provides a storage rack, which includes: a shelf 10, a support part 20, a first telescopic member 30, a second telescopic member 40, and a connecting member 50. The shelf 10 is provided with a chute 11 or a slider extending along the length direction of the shelf 10; the support part 20 is arranged on the shelf 10; the first telescopic member 30 is movably connected to the support part 20 and the first telescopic member 30 is slidably connected to the chute 11 or the slider. The first telescopic member 30 is provided with a first slideway 31, and the first slideway 31 extends obliquely along the length direction of the shelf 10; a part of the second telescopic member 40 is nested in the first telescopic member 30, and the second telescopic member 40 is slidably connected to the chute 11 or the slider. The second telescopic member 40 is provided with a second slideway 41, and the second slideway 41 extends obliquely along the length direction of the shelf 10 and is inclined in the same direction as the first slideway 31. The second slideway 41 and the first slideway 31 are partially overlapped; the connecting member 50 is movably connected to the support part 20, and the connecting member 50 penetrates through the first slideway 31 and the second slideway 41; the movement direction of the connecting member 50 intersects with the length direction of the shelf 10. When the connecting member 50 moves, the first telescopic member 30 and the second telescopic member 40 simultaneously expand and contract along the length direction of the shelf 10 under the drive of the connecting member 50.

[0051] By adopting the embodiment of the present disclosure, by providing a chute 11 or a slider extending along the length direction of the shelf 10 on the shelf 10, and both the first telescopic member 30 and the second telescopic member 40 are arranged to be slidably connected to the chute 11 or the slider. Under the limitation of the chute 11 or the slider, 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 out of or retract into the shelf 10, where the length direction of the shelf 10 is also Figure 1 the left-right direction in the figure.

[0052] By providing the support portion 20 and movably connecting the first telescopic member 30 with the support portion 20, the support portion 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 portion 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 connecting member with the support portion, the support portion can support the connecting member and the connecting member can move relative to the support portion.

[0053] By intersecting the movement direction of the connecting member 50 with the length direction of the shelf 10, that is, the movement direction of the connecting member 50 does not move in the left-right direction. By arranging the first slideway 31 on the first telescopic member 30 and the second slideway 41 on the second telescopic member 40, and the connecting member passing through the first slideway 31 and the second slideway 41, the connecting member can be connected to both the first slideway 31 and the second slideway 41. In this way, when the connecting member moves, under the limitation of the slide groove 11 or the slider of the shelf 10 and the first slideway 31 and the second slideway 41, the first telescopic member 30 or the second telescopic member 40 will not move along the movement direction of the connecting member, and under the limitation of the first slideway 31 and the second slideway 41, the movement of the connecting member 50 can be converted into the movement in the left-right direction, so that the first telescopic member 30 and the second telescopic member 40 can be driven by the connecting member 50 to perform telescopic movement in the left-right direction at the same time, that is, when the connecting member 50 moves, the first telescopic member 30 and the second telescopic member 40 can be moved toward or away from each other, so that the first telescopic member 30 and the second telescopic member 40 can be retracted or extended out of the shelf. 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 connecting member 50. Compared with the adjustment method in the related art, this embodiment only needs to adjust the position of the connecting member 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.

[0054] Specifically, combined Figure 1 and Figure 3 As shown in the figure, 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 sliding 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 sliding block adapted to the second slide groove.

[0055] Optionally, the dimension of the first chute along the length direction of the shelf 10 is equal to the distance between the first end and the second end of the first slideway 31.

[0056] In this way, the moving distance of the first telescopic member 30 can be jointly defined by the first chute, the first slider, the connecting member 50 and the first slideway 31, avoiding the situation that the connecting member 50 and the first slideway 31 are overstressed and broken or damaged.

[0057] Optionally, buffer members are provided at both ends of the first chute.

[0058] In this way, by providing the buffer members, the impact between the first telescopic member 30 and the first chute of the shelf 10 can be slowed down, reducing the impact noise.

[0059] Optionally, the dimension of the second chute along the length direction of the shelf 10 is equal to the distance between the first end and the second end of the second slideway 41.

[0060] In this way, the moving distance of the second telescopic member 40 can be jointly defined by the second chute, the second slider, the connecting member 50 and the second slideway 41, avoiding the situation that the connecting member 50 and the second slideway 41 are overstressed and broken or damaged.

[0061] Optionally, buffer members are provided at both ends of the second chute.

[0062] In this way, by providing the buffer members, the impact between the second telescopic member 40 and the second chute of the shelf 10 can be slowed down, reducing the impact noise.

[0063] Specifically, the buffer member can be a rubber pad or a silica gel pad. It can be understood that the specific form of the buffer member is not unique.

[0064] Optionally, the included angle between the moving direction of the connecting member 50 and the length direction of the shelf 10 is 90 degrees.

[0065] In this way, by symmetrically designing the first slideway 31 and the second slideway 41 with respect to the connecting member 50, the first telescopic member 30 and the second telescopic member 40 can move the same distance when the connecting member 50 rotates.

[0066] 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, both the first slideway 31 and the second slideway 41 are spiral, and the spirals of the first slideway 31 and the second slideway 41 are less than one turn.

[0067] By adopting the embodiments of the present disclosure, by setting the first telescopic member 30 as a cylindrical structure and setting the second telescopic member 40 as a cylindrical structure, it is not only convenient to connect the second telescopic member 40 to the first telescopic member 30, but also can 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 is used to support the second telescopic member 40, avoiding an increase in the movement resistance due to the connection between the second telescopic member 40 and the shelf 10.

[0068] By setting the first slideway 31 and the second slideway 41 as a spiral structure less than one turn, since the first telescopic member 30 and the second telescopic member 40 can only move in the left-right direction under the limitation of the chute 11 of the shelf 10, the first slideway 31 and the second slideway 41 can also only move in the left-right direction, and the connecting member 50 rotates relative to the first telescopic member 30. By setting the spiral to be less than one turn, in this way, it is not necessary to rotate the connecting member 50 for one turn or multiple turns to complete the contraction or extension of the first telescopic member 30 and the second telescopic member 40, thereby enabling the first telescopic member 30 and the second telescopic member 40 to quickly contract or extend, improving the convenience of user operation.

[0069] It should be noted that the first telescopic member 30 and the second telescopic member 40 can be square structures, the first slideway 31 is arranged on the upper surface of the first telescopic member 30, and the second slideway 41 is arranged on the 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.

[0070] Optionally, the included angle between the line connecting the first end of the first slideway 31 and the axis of the first telescopic member 30 and the 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.

[0071] By adopting the embodiments of the present disclosure, when the included angle is less than 30 degrees, the resistance for the user to rotate the connecting member 50 is large, and it is difficult for the user to rotate the connecting member 50; when the included angle is greater than 180 degrees, the angle for the user to rotate the connecting member 50 is too large, which is not convenient for the user to use.

[0072] Optionally, the included angle between the line connecting the first end of the second slideway 41 and the axis of the second telescopic member 40 and the 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.

[0073] In this way, when the included angle is less than 30 degrees, the resistance for the user to rotate the connecting member 50 is large, and it is difficult for the user to rotate the connecting member 50; when the included angle is greater than 180 degrees, the angle for the user to rotate the connecting member 50 is too large, which is not convenient for the user to use

[0074] Optionally, the angle between the line connecting the first end of the first slideway 31 and the axis of the first telescopic member 30 and the line connecting the second end of the first slideway 31 and the axis of the first telescopic member 30 is 90 degrees, and the angle between the line connecting the first end of the second slideway 41 and the axis of the second telescopic member 40 and the line connecting the second end of the second slideway 41 and the axis of the second telescopic member 40 is 90 degrees.

[0075] In this way, not only can the problem that the angle is too small and it is difficult for the user to rotate due to the large rotation resistance be avoided, but also the problem that the angle is too large and the user needs to rotate a large angle, resulting in difficult operation for the user, can be avoided.

[0076] Optionally, the shelf further includes: an elastic member 60, the elastic member 60 is disposed inside the first telescopic member 30, one end of the elastic member 60 is connected to the first telescopic member 30, and the other end of the 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 towards each other, the elastic member 60 is compressed.

[0077] By adopting the embodiment of the present disclosure, by providing the elastic member 60, the 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 elastic member 60 can make the second telescopic member 40 move away from the first telescopic member 30. In this way, the elastic member 60 can make the first telescopic member 30 and the second telescopic member 40 automatically extend. By setting the elastic member 60 to be compressed when the first telescopic member 30 and the second telescopic member 40 move towards each other, that is to say, the elastic member 60 can drive both 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, and avoiding the situation that the shelf 10 cannot be fixed due to the contraction of the first telescopic member 30 and the second telescopic member 40 caused by vibration or other reasons. In addition, by setting the elastic member 60 to be compressed when the first telescopic member 30 and the second telescopic member 40 move towards each other, that is to say, when the second telescopic member 40 is in the contracted position, the compression amount of the elastic member 60 reaches the maximum, which can avoid the situation that the connecting member 50 collides with the end of the corresponding chute 11 and is damaged or broken due to the user rotating the connecting member 50 too fast.

[0078] It should be noted that the elastic member 60 can be a spring, can also be a polyurethane elastomer, or can also be a rubber elastomer, etc. It can be understood that the specific form of the elastic member 60 is not unique.

[0079] Optionally, the support portion 20 includes: a support base 21, a mounting opening 211 is defined in the middle of the support base 21, and the mounting opening 211 is adapted to the first telescopic member 30 so that the support base 21 nests the first telescopic member 30.

[0080] With the embodiment of the present disclosure, by providing the support base 21 and defining an installation opening 211 adapted to the first telescopic member 30 in the middle of the support portion 20, the first telescopic member 30 can be inserted into the support base 21 along the installation opening 211, so that the support base 21 nests the first telescopic member 30 and supports the first telescopic member 30.

[0081] Specifically, the installation opening 211 extends in the left-right direction, enabling the first telescopic member 30 to be inserted into the support base 21 relative to the support base 21 in the left-right direction.

[0082] Optionally, the support portion 20 is provided on the upper end surface of the shelf 10 and at the rear of the shelf 10.

[0083] In this way, by arranging the support portion 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, which can prevent the first telescopic member 30 and the second telescopic member 40 from blocking the user from placing items, ensuring the convenience of the user to place items on the shelf 10. And compared with the setting method 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 setting position of this embodiment facilitates the user to operate the connecting member 50 connected to the support portion 20, improving the convenience of the user to use.

[0084] Optionally, the support portion 20 is provided at the front end of the shelf 10.

[0085] In this way, it is convenient for the user to operate the connecting member 50, improving the convenience of the user to use the shelf.

[0086] Optionally, a first track 212 and a second track are respectively provided on both sides of the support base 21, and both the first track 212 and the second track extend along the wall surface of the first telescopic member 30; the support portion 20 further includes: a connecting frame 22, defining a through hole 221, the through hole 221 is adapted to the connecting member, and is slidably connected to both the first track 212 and the second track, so that the connecting member is slidably connected to the support base 21.

[0087] With the embodiment 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 arranging 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 the through hole 221 adapted to the connecting member on the connecting frame 22, the connecting member can be connected to the connecting frame 22, so that the connecting member slides relative to the support base 21 driven by the connecting frame 22.

[0088] Specifically, the support base 21 includes a first support and a second support. The first support and the second support are spaced apart along the length direction of the shelf 10. A gap is formed between the first support and the second support. The gap corresponds to the through hole 221. The width dimension of the gap is adapted to the connecting member, so that the connecting member 50 passes through the gap and is connected to the first sliding groove 31 and the second sliding groove 41.

[0089] In this way, it is convenient to position and install the first telescopic member 30 and the support base 21, improving the convenience of user installation.

[0090] Optionally, a middle portion of the connecting member protrudes to form a clamping portion 51. The connecting frame 22 is provided with a clamping space 222 having a clamping opening. The clamping space 222 communicates with the through hole 221. The clamping opening is adapted to the clamping portion 51. When the clamping portion 51 is located within the clamping space 222, the connecting member has a first position and a second position, and the connecting member can rotate between the first position and the second position. When the connecting member is in the second position, the connecting member is fixedly connected to the connecting frame 22.

[0091] By adopting the embodiment of the present disclosure, by providing the clamping portion 51 on the connecting member and the clamping space 222 on the connecting frame 22, the connecting member can be clamped to the connecting frame 22. The connecting member can pass through the through hole 221 and the connecting frame 22 until the clamping portion 51 moves from the clamping opening to the clamping space 222, and the connection with the connecting frame 22 is completed by rotating the connecting member. This can not only ensure the reliable connection between the connecting member and the connecting frame 22, but also facilitate the user to disassemble the connecting member from the connecting frame 22, which is convenient for maintenance and replacement of the connecting member.

[0092] Optionally, the clamping space 222 includes a first accommodating cavity 2221 and a second accommodating cavity 2222. The first accommodating cavity 2221 communicates with the second accommodating cavity 2222. When the connecting member 50 is in the first position, the clamping portion 51 is located in the first accommodating cavity 2221. When the connecting member 50 is in the second position, the clamping portion 51 is located in the second accommodating cavity 2222. The distance between the upper wall surface and the lower wall surface of the second accommodating cavity 2222 is smaller than the distance between the upper wall surface and the lower wall surface of the first accommodating cavity 2221.

[0093] In this way, by setting the distance between the upper wall surface and the lower wall surface of the second accommodating cavity 2222 to be smaller than the distance between the upper wall surface and the lower wall surface of the first accommodating cavity 2221, when the clamping portion 51 rotates to the second position, the frictional resistance between the wall surface of the clamping space 222 and the clamping portion 51 can be increased, thereby preventing the clamping portion 51 from disengaging from the second accommodating cavity 2222, and ensuring the connection reliability between the connecting member 50 and the connecting frame 22.

[0094] 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 gradually decreases in the direction towards the connecting member.

[0095] 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 connecting member 50 and the connecting frame 22 .

[0096] Specifically, combined Figure 4 As shown in , the clamping portion 51 is a fan-shaped structure, the number of the clamping portions 51 is two, and the two clamping portions 51 are evenly spaced and arranged on the connecting piece.

[0097] In this way, the connection stability between the connecting piece and the connecting seat can be ensured.

[0098] 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.

[0099] 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 smaller than the spiral angle of the second slide section 312, when the connecting member 50 moves along the first slide section 311, compared with the connecting member 50 sliding along the second slide section 312, the distance moved by the first telescopic member 30 when the connecting member 50 rotates the same angle is smaller, that is, the contraction distance of the first telescopic member 30 is shorter. When the user starts to rotate the connecting member 50, the first telescopic member 30 can have a larger acceleration, and the user can use a smaller force to drive the first telescopic member 30 to retract, thereby improving the user's operational convenience. In addition, when the first telescopic member 30 is extended, when the connecting member 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, thereby avoiding the user turning the connecting member 50 too fast or the elastic member 60 driving the first telescopic member 30 to automatically extend too fast, causing the connecting member 50 to hit the end of the first slide 31, resulting in the connecting member breaking or the first slide 31 being damaged.

[0100] 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.

[0101] In this way, by setting the spiral angle of the third sliding section 313 to be smaller than that of the second sliding section 312, when the connecting member 50 moves along the third sliding section 313, compared with when the connecting member 50 slides along the second sliding section 312, for the same angle of rotation of the connecting member 50, the moving distance of the first telescopic member 30 is smaller, that is to say, the moving distance of the first telescopic member 30 is shorter. When the first telescopic member 30 is contracting, the contraction 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 contraction position, and avoiding the problem that the connecting member 50 hits the end of the first slideway 31 due to the user rotating the connecting member 50 too fast, resulting in the fracture of the connecting member 50 or the damage of the first slideway 31. When the first telescopic member 30 is extending, the first telescopic member 30 can have a greater acceleration, which is convenient for driving the movement of the first telescopic member 30. Even when the driving force of the elastic member 60 is continuously decreasing, the connecting member 50 can slide to the first sliding section 311 under the action of the elastic force of the elastic member 60, so that the first telescopic member 30 extends a sufficient distance.

[0102] Optionally, the second slideway 41 includes a fourth sliding section 411 and a fifth sliding section 412. The fourth sliding section 411 is located at the end of the second slideway 41 facing the first telescopic member 30. The fourth sliding section 411 is connected to the fifth sliding section 412. Among them, the angle of the spiral angle of the fourth sliding section 411 is smaller than the angle of the spiral angle of the fifth sliding section 412.

[0103] In this way, since the interior of the refrigeration device is in a low-temperature environment for a long time, due to the action of the condensation phenomenon, there will be a certain adhesion force on the internal items, making it difficult to move. By setting the spiral angle of the fourth sliding section 411 to be smaller than that of the fifth sliding section 412, when the connecting member 50 moves along the fourth sliding section 411, compared with when the connecting member 50 slides along the fifth sliding section 412, for the same angle of rotation of the connecting member 50, the moving distance of the second telescopic member 40 is smaller, that is to say, the contraction distance of the second telescopic member 40 is shorter. When the user starts to rotate the connecting member 50, the second telescopic member 40 can have a greater acceleration, and the user can use a smaller force to drive the second telescopic member 40 to expand and contract, improving the operation convenience of the user. In addition, when the second telescopic member 40 is extending, when the connecting member 50 moves from the fifth sliding section 412 to the fourth sliding section 411, the extending 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 extending position, and avoiding the problem that the connecting member 50 hits the end of the second slideway 41 due to the user rotating the connecting member 50 too fast or the driving speed of the elastic member 60 driving the second telescopic member 40 to automatically extend too fast, resulting in the fracture of the connecting member 50 or the damage of the second slideway 41.

[0104] Optionally, the second slideway 41 further includes: a sixth slide section 413, which is located at the end of the second slideway 41 away from the first telescopic member 30, and the sixth slide section 413 is connected to the fifth slide section 412, wherein the angle of the spiral angle of the sixth slide section 413 is smaller than the angle of the spiral angle of the fifth slide section 412.

[0105] In this way, by setting the spiral angle of the sixth slide section 413 to be smaller than that of the fifth slide section 412, when the connecting member 50 moves along the sixth slide section 413, compared with the connecting member 50 sliding along the fifth slide section 412, the connecting member 50 rotates by the same angle and the second telescopic member 40 moves a shorter distance. That is to say, the moving distance of the second telescopic member 40 is shorter. When the second telescopic member 40 is contracting, the contraction 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 contraction position, and avoiding the problem that the connecting member 50 hits the end of the second slideway 41 due to the user rotating the connecting member 50 too fast, resulting in the fracture of the connecting member 50 or the damage of the second slideway 41. When the second telescopic member 40 is extending, the second telescopic member 40 can have a greater acceleration, which is convenient for driving the second telescopic member 40 to move. Even when the driving force of the elastic member 60 is continuously decreasing, the connecting member 50 can slide to the sixth slide section 413 under the action of the elastic force of the elastic member 60, so that the second telescopic member 40 extends a sufficient distance.

[0109] In this way, by providing the support ribs 71 on the inner container 70, the support ribs 71 can support the shelf 10. By providing the 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 out of the shelf 10, the first telescopic member 30 or the second telescopic member 40 extends into the fixing holes of the corresponding side wall, which can limit the position of the shelf 10, and further limit the position of the shelf 10 relative to the inner container 70.
