Description

Technical Field

[0001] This invention relates to the field of sink technology, and more specifically to a shelf assembly and sink for use in sinks. Background Technology

[0002] With the widespread use of sinks in modern kitchens, various types of sink racks and fruit and vegetable baskets have been designed to match them. Some sink racks only have the functions of draining water and holding fruits and vegetables. Since the surface of the sink rack is often wet, it will cause dampness and mold in the cabinet when it is stored, requiring special air drying. Currently, sink racks are usually large and cannot be folded, taking up a lot of space no matter where they are placed, which is very inconvenient.

[0003] To address the aforementioned issues, Chinese invention patent application CN202110271761.0 (publication number CN115067780A) discloses a folding vegetable basket and washing machine for a sink. In this folding vegetable basket for a sink, a secondary basket is connected to the first opening or the first base plate of the main basket. When the main basket is in its first usage state, the secondary basket is connected to the first opening of the main basket, so that the main basket and the secondary basket meet at the opening, and the first and second placement sections join to form an upward-facing storage compartment. When the main basket is in its second usage state, the secondary basket is at least partially located below the first base plate of the main basket, providing support for the main basket. This folding vegetable basket design, with its main and secondary baskets working together to switch states, effectively utilizes the folded state of the basket while meeting the usage requirements of a conventional fruit and vegetable basket. It not only avoids the space occupied by storing items and the fruit and vegetable basket separately, but also ensures stable support in the folded state thanks to the secondary basket, making it very convenient and practical.

[0004] Although this folding basket can be folded to reduce space usage, when it is not folded, the main basket and the secondary basket are only positioned by rotating the pivot and connecting part. The relative stability of the two baskets is poor, especially when the items in the folding basket are heavy, the two baskets are prone to relative rotation, and the items cannot be held well. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a shelf assembly for a water tank with good relative stability between the two baskets in the unfolded state, in light of the current state of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a water tank that uses the above-mentioned shelf assembly, in view of the current state of the prior art.

[0007] The technical solution adopted by the present invention to solve the first technical problem mentioned above is as follows: a shelf assembly for a sink, comprising two baskets, each basket having a drain hole, each basket comprising a bottom plate and a side plate extending upward from a partial periphery of the bottom plate, such that each basket has an upward-facing first opening and a side-facing second opening, the side of the bottom plate of the basket located at the second opening is called the first side, the first side of the two baskets are rotatably connected by a rotating structure, the rotation axis of the rotating structure extending along the length direction of the first side, so that the shelf assembly has a first use state and a second use state;

[0008] When the shelf assembly is in its first use state, the second openings of the two baskets are joined together, and the placement areas of the two baskets are combined to form an upward-facing storage slot.

[0009] When the shelving assembly is in its second use state, one basket is located below the other basket;

[0010] The shelf assembly is characterized in that it further includes a positioning mechanism, the positioning mechanism comprising:

[0011] The first positioning block is located on one of the baskets;

[0012] The second positioning block is provided on another basket. When the shelf is in the first use state, the second positioning block can be detachably bound together with the first positioning block. When the shelf is in the second use state, the first positioning block and the second positioning block are separated.

[0013] An unlocking structure, located on one of the baskets, is used to release the constraints between the first positioning block and the second positioning block.

[0014] In the above scheme, the wall surface of the side plate of the basket located at the second opening is called the mating surface, the two baskets are called the first basket and the second basket, the first positioning block is provided on the first basket, and the second positioning block is provided on the second basket.

[0015] A limiting groove is provided on the side plate of the first basket near the second opening. The limiting groove has a first groove and a second groove, and the first groove passes through the mating surface of the side plate.

[0016] The second positioning block can extend into or exit the limiting groove from the first slot, and the first positioning block is disposed in the limiting groove and can move toward or away from the second positioning block;

[0017] The unlocking structure can have various structural forms, including...

[0018] The unlocking rod is movable toward or away from the limiting groove. The first end of the unlocking rod can extend into the limiting groove from the second groove opening and be detachably connected to the first positioning block. In this state, the second positioning block is pressed by the first positioning block to abut against the wall of the limiting groove.

[0019] The first elastic element acts on the first positioning block, causing the first positioning block to maintain a tendency to move away from the second positioning block;

[0020] The drive rod can abut against the second end of the unlocking rod and push the unlocking rod toward the limiting groove;

[0021] The second elastic element acts on the unlocking lever, causing the unlocking lever to maintain a tendency to move away from the limiting groove.

[0022] In order to enable the unlocking rod to be detachably connected to the first positioning block, the first positioning block is provided with a slot, and the first end of the unlocking rod is detachably inserted into the slot, wherein the extension direction of the unlocking rod is perpendicular to the movement direction of the first positioning block.

[0023] Preferably, the portion of the side panel of the first basket facing the second opening is referred to as the first sidewall. The drive rod is located on the outside of the first sidewall and is rotatably connected to the first basket via a connecting rod. The drive rod can be in a first position and a second position. In the first position, the connecting rod extends vertically, the drive rod is located at the bottom of the connecting rod and abuts against the unlocking rod, and the drive rod is against the first sidewall of the first basket. In the second position, the connecting rod extends laterally away from the first basket. The drive rod and the connecting rod together form a hanging rack for hanging items. The drive rod can not only drive the unlocking rod to move, but can also be used to hang items such as rags, making it a multi-purpose device.

[0024] To ensure proper coordination between the unlocking lever, the first positioning block, and the second positioning block, the limiting groove includes a connected vertical section and a horizontal section. The vertical section extends vertically, and the horizontal section extends horizontally. One end of the horizontal section is connected to the vertical section, and the other end is open and called the first groove. The vertical section is provided with a second groove. The first positioning block is movably positioned in the vertical section of the limiting groove, and the second positioning block can extend into or retract from the horizontal section.

[0025] To facilitate the entry and exit of the second positioning block into the transverse section of the limiting groove, preferably, the transverse section of the limiting groove is tapered with a gradually narrowing diameter along the direction in which the second positioning block is inserted. The tapered structure not only guides the second positioning block into the limiting groove but also facilitates its entry and exit.

[0026] In the above scheme, when the shelf assembly is in the first use state, the drive rod is in the first position. At this time, the drive rod is close to the first side wall of the first basket and will not affect the placement of the shelf assembly in the water tank. When the shelf assembly is in the second use state, the drive rod is in the second position. At this time, the drive rod is away from the first side wall of the first basket and can hang items.

[0027] To position the drive rod when it is in the first and second positions, one end of the connecting rod is called a connecting part. The first basket body has a mounting shaft, and the connecting part is rotatably mounted on the mounting shaft. A limiting member is also provided on the side plate of the first basket body. The connecting part and the limiting member are detachably bound together by a locking block and a locking groove. When the drive rod is in the first or second position, the connecting part and the limiting member are connected. When the drive rod needs to switch positions, the connecting part and the limiting member disengage, allowing the connecting rod to rotate.

[0028] Because the second positioning block extends out of the second basket in order to fit into the limiting groove, when the shelf assembly switches to the second use state, the second positioning block will interfere with the side wall of the groove, affecting the folding of the second basket. Therefore, the second positioning block and the second basket are rotatably connected. When the shelf assembly is in the second use state, the second positioning block extends vertically to avoid interference between the second positioning block and the first basket.

[0029] To enable the second positioning block to rotate, the second basket is provided with a vertically extending linkage rod. This linkage rod can move vertically relative to the second basket. At least a portion of the linkage rod along its length has at least two first teeth. The portion of the second positioning block connected to the second basket has a first gear that meshes with the first teeth. The vertical movement of the linkage rod drives the first gear to rotate, causing the second positioning block to rotate synchronously.

[0030] To improve the stability of the shelf assembly placed in the tank, the second basket is provided with a plate located outside the side plate. In the first use state of the shelf assembly, the plate extends horizontally, and in the second use state of the shelf assembly, the plate extends vertically. The plate serves as a shelf for placing on the support part of the tank body.

[0031] To prevent interference between the shelf assembly and the first basket when the shelf assembly is in its second use state, thus affecting the folding of the second basket, a vertically extending rod is provided on the second basket. This rod is vertically movable relative to the second basket. At least a portion of the rod has at least two second teeth along its length, and the shelf assembly has a second gear that meshes with these teeth. The vertical movement of the rod drives the second gear to rotate, causing the shelf assembly to rotate accordingly.

[0032] Drive mechanisms could be set separately for the vertical rod and the linkage rod, but this would involve more components. Therefore, the vertical rod and the linkage rod are fixedly connected by a connecting rod, so that only the vertical rod or the linkage rod needs to be driven.

[0033] It's possible to set up a motor to drive the vertical rod or linkage rod to move, but this involves more components. Therefore, one end of the vertical rod extends out of the bottom plate of the second basket. When the shelf assembly is in the second use state, the vertical rod abuts against the bottom plate of the first basket and moves downwards, while the vertical rod maintains an upward tendency under the action of the third elastic element. Thus, when the shelf assembly switches to the second use state, the vertical rod abuts against the bottom plate of the first basket and moves downwards. When the shelf assembly switches from the second use state to the first use state, the vertical rod disengages from the bottom plate of the first basket, and the vertical rod moves in the opposite direction under the action of the third elastic element. In this way, no driving component is needed to drive the vertical rod to move up and down, and the linkage rod moves up and down synchronously.

[0034] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: a water tank, characterized in that: it includes a tank body and the above-mentioned shelf assembly, the top of the tank body is open, and the shelf assembly is placed in the tank body.

[0035] Preferably, the tank is provided with a spray element located below the shelf assembly, and the spray element has spray holes facing the shelf assembly to clean the items in the shelf assembly.

[0036] Compared with the prior art, the advantages of the present invention are as follows: By setting a positioning mechanism, when the shelf assembly is in the first use state, the two baskets are relatively fixed together by the positioning mechanism, which has good stability and solves the problem of poor relative stability between the two baskets affecting the placement of items; when the shelf assembly needs to switch to the second use state, the positioning mechanism can release the relative fixation of the two baskets without affecting the folding of the two baskets; when there are many items to be placed, the shelf assembly is in the first use state, and when there are few items to be placed, the shelf assembly is in the second use state, which occupies little space.

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0048] like Figures 1-10 As shown, the water tank in this preferred embodiment includes a tank body 1 and a shelf assembly. The top of the tank body 1 is open, and the shelf assembly is placed in the tank body 1. The shelf assembly A includes a positioning mechanism and two baskets.

[0049] like Figure 4 As shown, each basket has a drain hole 21. Each basket includes a bottom plate 22 and a side plate 23 extending upward from a partial periphery of the bottom plate 22, so that each basket has an upward first opening 24 and a side opening 25. The bottom plate 22 and the side plate 23 form a placement area 26 for placing items. Tableware, pots and pans, fruits and vegetables and other items can be placed in the basket.

[0050] The side of the bottom plate 22 of the basket located at the second opening 25 is called the first side. In this embodiment, the bottom plate 22 is square and includes four sides, namely the first side, the second side, the third side and the fourth side. The first side and the fourth side are arranged opposite each other, and the second side and the third side are arranged opposite each other. The first side, the second side, the fourth side and the third side are connected end to end in sequence. The part of the side plate 23 corresponding to the fourth side is called the first sidewall. That is, the part of the side plate 23 of the basket facing the second opening 25 is called the first sidewall, and the part of the side plate 23 corresponding to the second side and the third side is called the second sidewall.

[0051] The first sides of the two baskets are rotatably connected by a rotating structure, allowing the shelving assembly to have a first usage state and a second usage state. In the first usage state, as... Figure 4 As shown, the second openings 25 of the two baskets are joined together, and the placement sections 26 of the two baskets are combined to form an upward-facing storage slot; when the shelf assembly is in its second use state, as... Figure 9 As shown, one basket is located below the other, which is equivalent to the two baskets being folded together.

[0052] The sink can be a regular sink, or it can have a spray unit 27 installed in it. The spray unit 27 is located below the shelf assembly and has spray holes that spray towards the shelf assembly to clean the items in the shelf assembly. In this case, the sink is used as a functional compartment of the dishwasher. The spray unit 27 can adopt the structure of an existing spray arm.

[0053] In this embodiment, there are two water tanks. Figure 1 The water tank on the left is a regular water tank. Figure 1 The sink on the right is the dishwasher's functional compartment. The shelf assembly, in its first-use state, can be placed in either a regular sink or the dishwasher's functional compartment, such as... Figure 2 , 3 As shown; Figure 1 The rear of the water tank 1 on the left side has a recessed area with a rearward groove to form a drain area 11. The shelf assembly in the second use state can be placed in the drain area 11, such as... Figure 1 As shown.

[0054] To ensure the shelf assembly is stably placed in the trough 1, at least one of the baskets' side plates 23 is provided with a shelf, and the trough 1 is provided with a support portion 12 for placing the shelf. The support portion 12 can be disposed on the inner wall surface of the circumferential wall of the trough 1, or it can be disposed on the top wall surface of the trough 1; in this embodiment, Figure 1 The shelf 12 on the left side of the trough 1 is the top wall of the trough 1. The shelf assembly in the trough 1 is mainly used to place items that need to drain. Figure 1 The shelf 12 of the tank 1 on the right side is set on the inner wall of the peripheral wall of the tank 1. The shelf assembly is mainly used to place items that need to be cleaned.

[0055] like Figure 8 As shown, the rotating structure includes a pin 28 on one of the baskets and a shaft hole 29 on the other basket. The pin 28 extends along the length of the first side and is rotatably inserted into the shaft hole 29 about its axis. Since displacement between the two baskets is easily generated when the shelf assembly is in its first use state, relying solely on the cooperation of the pin 28 and the shaft hole 29, a positioning mechanism is also provided. The positioning mechanism includes a first positioning block 31, a second positioning block 32, and an unlocking structure.

[0056] The first positioning block 31 is disposed on one of the baskets, and the second positioning block 32 is disposed on the other basket. When the shelf is in the first use state, the second positioning block 32 can be detachably bound together with the first positioning block 31. When the shelf is in the second use state, the first positioning block 31 and the second positioning block 32 are separated. The unlocking structure is disposed on one of the baskets and is used to release the constraint between the first positioning block 31 and the second positioning block 32.

[0057] The wall surface of the side plate 23 of the basket located at the second opening 25 is called the mating surface, that is, the side wall surface of the second side wall located at the second opening 25 is the mating surface.

[0058] The two baskets are referred to as the first basket 2a and the second basket 2b, respectively. In the second use state of the shelf assembly, the second basket 2b is located below the first basket 2a. A first positioning block 31 is provided on the first basket 2a, and a second positioning block 32 is provided on the second basket 2b.

[0059] like Figure 5 , 6 As shown in Figure 7, a limiting groove 33 is provided on the side plate 23 of the first basket 2a near the second opening 25. The limiting groove 33 has a first slot 331 and a second slot 332. The first slot 331 penetrates the mating surface of the side plate 23. In this embodiment, the limiting groove 33 includes a connected vertical section 333 and a horizontal section 334. The vertical section 333 extends vertically, and the horizontal section 334 extends horizontally. One end of the horizontal section 334 is connected to the upper end of the vertical section 333, and the other end is open and called the first slot 331. The vertical section 333 is provided with the second slot 332. The second positioning block 32 can extend into or out of the horizontal section 334 from the first slot 331. In order to facilitate the second positioning block 32 to enter or exit the horizontal section 334 of the limiting groove 33, preferably, the horizontal section 334 of the limiting groove 33 is tapered with a gradually narrowing diameter along the direction in which the second positioning block 32 is inserted into the horizontal section 334.

[0060] The first positioning block 31 is movably disposed in the vertical section 333 of the limiting groove 33, so as to move toward or away from the second positioning block 32. The first positioning block 31 can press the second positioning block 32, so that the second positioning block 32 abuts against the top wall surface of the horizontal section 334, thereby positioning the second positioning block 32 in the limiting groove 33.

[0061] The unlocking structure includes a first elastic element 341, an unlocking lever 34, a drive lever 35, and a second elastic element 351.

[0062] The unlocking rod 34 can move toward or away from the limiting groove 33. The first end of the unlocking rod 34 can extend into the limiting groove 33 from the second slot 332. The extension direction of the unlocking rod 34 is perpendicular to the moving direction of the first positioning block 31. The first positioning block 31 is provided with a slot 311. The first end of the unlocking rod 34 can be detachably inserted into the slot 311 so that the unlocking rod 34 and the first positioning block 31 can be detachably connected. When the unlocking rod 34 and the first positioning block 31 are connected, the first positioning block 31 presses the second positioning block 32 so that the second positioning block 32 abuts against the wall of the limiting groove 33.

[0063] The first elastic element 341 acts on the first positioning block 31, causing the first positioning block 31 to maintain a tendency to move away from the second positioning block 32. The first elastic element 341 is a spring, with one end abutting against the bottom wall of the limiting groove 33 and the other end abutting against the first positioning block 31.

[0064] The second elastic element 351 acts on the unlocking rod 34, causing the unlocking rod 34 to maintain a tendency to move away from the limiting groove 33. A first guide groove 201 extending horizontally is provided on the second side wall of the first basket 2a. The unlocking rod 34 is disposed in the first guide groove 201 and can move along the length of the first guide groove 201 to guide the movement trajectory of the unlocking rod 34. The second elastic element 351 is a spring, with one end abutting against the unlocking rod 34 and the other end abutting against the wall of the first guide groove 201.

[0065] The drive rod 35 abuts against the second end of the unlocking rod 34 and pushes the unlocking rod 34 toward the limiting groove 33. The drive rod 35 is located on the outer side of the first side wall of the first basket 2a, and is rotatably connected to the first basket 2a via the connecting rod 352. The drive rod 35 can be in a first position and a second position. In the first position, the connecting rod 352 extends vertically, the drive rod 35 is located at the bottom of the connecting rod 352 and abuts against the unlocking rod 34, and the drive rod 35 is against the first side wall of the first basket 2a. In the second position, the connecting rod 352 extends laterally away from the first basket 2a. The drive rod 35 and the connecting rod 352 together form a hanging rack for hanging items. The drive rod 35 can not only drive the unlocking rod 34 to move, but can also be used to hang items such as rags, making it a multi-purpose device.

[0066] When the shelf assembly is in the first use state, the drive rod 35 is in the first position. At this time, the drive rod 35 is close to the first side wall of the first basket 2a. The drive rod 35 will not interfere with the tank 1 and will not affect the placement of the shelf assembly in the tank 1 of the water tank. When the shelf assembly is in the second use state, the drive rod 35 is in the second position. At this time, the drive rod 35 is away from the first side wall of the first basket 2a and can hang items.

[0067] One end of the connecting rod 352 is called the connecting part 353. A mounting shaft 202 is provided on the second side wall of the first basket 2a. The connecting part 353 is rotatably mounted on the mounting shaft 202. A limiting member 4 is also provided on the second side wall of the first basket 2a. The connecting part 353 and the limiting member 4 are detachably constrained together by a locking block 354 and a locking groove 41. When the drive rod 35 is in the first or second position, the connecting part 353 and the limiting member 4 are connected together. When the drive rod 35 needs to switch positions, the connecting part 353 and the limiting member 4 disengage, allowing the connecting rod 352 to rotate. In this embodiment, the locking groove 41 is provided on the connecting part 353, and the locking block 354 is provided on the limiting member 4. The locking block 354 is a cone shape that gradually narrows in diameter away from the connecting part 353. The locking groove 41 is a cone shape adapted to the locking block 354. Under external force, the locking block 354 can disengage from the locking groove 41.

[0068] Because the second positioning block 32 extends laterally out of the second basket 2b in order to be able to extend into the limiting groove 33, when the shelf assembly switches to the second use state, the second positioning block 32 will interfere with the first basket 2a, affecting the folding of the second basket 2b. Therefore, the second positioning block 32 and the second basket 2b can be rotatably connected. When the shelf assembly is in the second use state, the second positioning block 32 extends vertically to avoid interference between the second positioning block 32 and the side wall of the groove 1.

[0069] like Figure 7 , 10 As shown, the second basket 2b is provided with a vertically extending linkage rod 51. The linkage rod 51 can move vertically relative to the second basket 2b. At least a portion of the linkage rod 51 has at least two first teeth 511 along its length. The part of the second positioning block 32 connected to the second basket 2b is provided with a first gear 321 that meshes with the first teeth 511. The vertical movement of the linkage rod 51 drives the first gear 321 to rotate, and the second positioning block 32 rotates synchronously.

[0070] The first basket 2a is provided with a shelf 203, which can be placed on the resting part 12 of the tank 1 to position the shelf assembly. However, when the shelf assembly is in the first use state, it can hold a lot of items and is relatively heavy. The positioning effect of the shelf 203 on the first basket 2a alone is not good. Therefore, in order to improve the stability of the shelf assembly placed in the tank 1, the second basket 2b is provided with a plate 204 located outside the side plate 23. When the shelf assembly is in the first use state, the plate 204 extends horizontally. At this time, the plate 204 serves as a shelf for placing on the resting part 12 of the tank 1. When the shelf assembly is in the second use state, the plate 204 extends vertically and will not interfere with the side wall of the tank 1.

[0071] The second basket 2b is also provided with a vertically extending vertical rod 52, which can move vertically relative to the second basket 2b. At least a portion of the vertical rod 52 has at least two second teeth 521 along its length. The plate 204 is provided with a second gear 205 that meshes with the second teeth 521. The vertical movement of the vertical rod 52 drives the second gear 205 to rotate, and the plate 204 rotates accordingly.

[0072] The vertical rod 52 and the linkage rod 51 are fixedly connected by the connecting rod 53, so that only the vertical rod 52 or the linkage rod 51 needs to be driven to achieve synchronous movement of the two. One end of the vertical rod 52 extends out of the bottom plate 22 of the second basket 2b. When the shelf assembly is in the second use state, the vertical rod 52 abuts against the bottom plate 22 of the first basket 2a and moves downward, while the vertical rod 52 maintains an upward tendency under the action of the third elastic element 522. Thus, when the shelf assembly switches to the second use state, the vertical rod 52 abuts against the bottom plate 22 of the first basket 2a and moves downward. When the shelf assembly switches from the second use state to the first use state, the vertical rod 52 disengages from the bottom plate 22 of the first basket 2a, and the vertical rod 52 moves in the opposite direction under the action of the third elastic element 522. In this way, without the need for any driving components, the vertical rod 52 can be driven to move up and down, and the linkage rod 51 can move up and down synchronously.

[0073] In this embodiment, the second sidewall of the second basket 2b is provided with a second guide groove 206 and a third guide groove 207 that extend vertically. The linkage rod 51 is disposed in the second guide groove 206 and can move along the second guide groove 206. The vertical rod 52 is disposed in the third guide groove 207 and can move along the third guide groove 207. The third elastic member 522 is a spring, one end of which abuts against the vertical rod 52 and the other end of which abuts against the third guide groove 207.

[0074] In this embodiment, there are two sets of positioning mechanisms, which are respectively set on both sides of the second opening 25 of the two baskets.

[0075] The working process of the shelf assembly in this embodiment is as follows:

[0076] When the shelf assembly is in its first use state, the shelf assembly can be placed in... Figure 1 In the trough 1 on the left or right side, the second openings 25 of the two baskets are joined together, and the placement sections 26 of the two baskets are joined together to form an upward-facing storage trough. The second positioning block 32 is limited in the limiting groove 33. The drive rod 35 is in the first position and abuts against the unlocking rod 34. The shelf 203 on the first basket 2a and the plate 204 on the second basket 2b are placed on the placement part 12 of the trough 1.

[0077] When the shelf assembly needs to be switched to the second use state, first rotate the connecting rod 352. The drive rod 35 releases the restriction on the unlocking rod 34. Under the action of the second elastic member 351, the unlocking rod 34 moves away from the limiting groove 33, releasing the lock on the second positioning block 32. Under the action of the first elastic member 341, the second positioning block 32 moves away from the first positioning block 31, releasing the pressure on the first positioning block 31. Then, force is applied to the second basket 2b to make the pin 28 of the rotating structure rotate around the shaft hole 29. The second positioning block 32 disengages from the limiting groove 33, and the second basket 2b rotates to below the first basket 2a. The shelf assembly is in the second use state and can be placed in... Figure 1 In the draining area of ​​the trough 1, the bracket formed by the unlocking rod 34 and the connecting rod 352 can hang items such as rags; in addition, when the second basket 2b rotates to the state where the vertical rod 52 abuts against the bottom plate 22 of the first basket 2a, the second basket 2b continues to rotate, the vertical rod 52 drives the linkage rod 51 to move downward synchronously, the first gear 321 and the second gear 205 both rotate, the plate 204 extends vertically, and the second positioning block 32 extends vertically to prevent the plate 204 and the second positioning block 32 from abutting against the side wall of the trough 1;

[0078] When the shelf assembly needs to be switched back to the first use state, the second basket 2b is rotated, and the bottom plate 22 of the first basket 2a disengages from the vertical rod 52. Under the action of the third elastic element 522, the vertical rod 52 drives the linkage rod 51 to move synchronously in the opposite direction. The first gear 321 and the second gear 205 rotate, causing the second positioning block 32 to rotate towards the first basket 2a, and the plate 204 to rotate to a horizontal state. Then, the connecting rod 352 is rotated so that the drive rod 35 drives the unlocking rod 34 to move towards the limiting groove 33 until the unlocking rod 34 is inserted into the slot 311 of the first positioning block 31, thereby locking the first positioning block 31. At this time, the second positioning block 32 is inserted into the limiting groove 33 and is pressed against the wall of the limiting groove 33 by the first positioning block 31. At this time, the shelf assembly can be placed in the groove 1, and the shelf 203 on the first basket 2a and the plate 204 on the second basket 2b are both placed on the placement part 12.
