The limit block 330 and the limit switching mechanism 300 can be switched between a locked state and an unlocked state in a controlled manner; wherein, in the locked state, the inner sleeve assembly 310 is clamped with the outer sleeve assembly 320, and the limit block 330 abuts against the limit groove 15 on the limit clamping strip 14 to fix the shelf body 200; when the inner sleeve assembly 310 and the outer sleeve assembly 320 are released from the clamping and move along their own axial direction, the limit block 330 can be driven to rotate and disengage from the limit groove 15 to switch to the unlocked state.
[0047] Optionally, the refrigerator includes an inner tank 10, and the front side of the inner tank 10, that is, the first side facing the user, is set to be open, so as to form an open storage space. The inner tank 10 includes a back plate 13 and a first side wall 11 and a second side wall 12 that are arranged opposite to each other and extend in the vertical direction, wherein the inner side wall surfaces of the first side wall 11 and the second side wall 12 are provided with supporting ribs that are arranged opposite to each other, and the supporting ribs at the same height form a group of supporting ribs, and the shelf body 200 can be installed on a group of supporting ribs to separate the space in the inner tank 10, so that food or other items can be stored on the shelf body 200. Optionally, a plurality of supporting ribs are arranged at intervals along the height direction of the first side wall 11, and a plurality of supporting ribs are also arranged at intervals along the height direction of the second side wall 12 corresponding to the first side wall 11, so as to form a plurality of groups of supporting ribs, so as to adjust the height of the shelf body 200.
[0048] Optionally, the limit switching mechanism 300 is disposed below the shelf body 200 to avoid occupying the space above the shelf body, thereby facilitating improving the space utilization above the shelf body 200 .
[0049] Optionally, the limit clamping strip 14 extends vertically, that is, extends along the height direction of the first side wall 11 or the second side wall 12, and is arranged between two adjacent support ribs. In this way, the limit switching mechanism 300 arranged below the shelf body 200 is conveniently clamped in the limit groove 15.
[0050] Optionally, the limiting groove 15 is arranged on the side wall of the limiting clip 14 facing the back plate 13 of the inner liner 10 to prevent the connecting corners of the side wall of the limiting groove 15 from scratching the user.
[0051] Optionally, the limit switching mechanism 300 is respectively disposed on the first side 210 and the second side 220 to limit the two side edges of the shelf body 200 respectively, so as to improve the stability of limiting the shelf body 200.

The outer sleeve assembly 320 is fixedly connected to the shelf body 200, and the inner sleeve assembly 310 can move relative to the outer sleeve assembly 320 along its own axis. The outer sleeve assembly 320 has a limit block 330 slidably connected to the inner sleeve assembly 310, and the limit switching mechanism 300 can be controlled to switch between a locked state and an unlocked state. When the inner sleeve assembly 310 moves along its own axial direction relative to the outer sleeve assembly 320 toward the back plate 13, the limit block 330 can be driven to rotate along the circumferential direction of the outer sleeve assembly 320, so that the limit block 330 rotates into the limit groove 15 and abuts against the side wall of the limit groove 15. At this time, the inner sleeve assembly 310 is clamped with the outer sleeve assembly 320 to improve the stability of the limit switching mechanism 300 when it is in the locked state; when the inner sleeve assembly 310 is in contact and clamped with the outer sleeve assembly 320, the inner sleeve assembly 310 moves along its own axial direction relative to the outer sleeve assembly 320 toward the direction away from the back plate 13, which can drive the limit block 330 to rotate in the opposite direction along the circumferential direction of the outer sleeve assembly 320, so that the limit block 330 is rotated out of the limit groove 15, so that the limit switching mechanism 300 is switched to the unlocked state.
[0053] The shelf for refrigerator provided by the embodiment of the present disclosure can be locked or unlocked by the limit switch mechanism arranged on the first side and the second side of the shelf body. By controlling the rotation of the outer sleeve assembly relative to the inner sleeve assembly, the limit block can be driven to rotate, so that the outer sleeve assembly is rotated and switched to a locked state, so that the inner sleeve assembly is clamped with the outer sleeve assembly, and the limit block abuts against the limit groove on the limit clamping strip, thereby locking the first side of the shelf body with the first side wall of the inner liner, and locking the second side of the shelf body with the second side wall of the inner liner, so that the stability and firmness of the shelf body can be improved, and the shelf can be prevented from falling due to the movement or shaking of the refrigerator or the storage device; in addition, when the shelf body needs to be removed, the outer sleeve assembly can be rotated relative to the inner sleeve assembly by releasing the clamping of the inner sleeve assembly and the outer sleeve assembly, so as to drive the limit block to rotate, so that the outer sleeve assembly is rotated and switched to an unlocked state, so as to drive the limit block to rotate and disengage from the limit groove.

In this way, the structure of the limit switching mechanism 300 can be ensured to be more compact.
[0056] The following description is based on the example that the limit switch mechanism 300 is located at the first side edge 210. Pushing the connecting push rod 340 to move toward the back plate 13 can drive the inner sleeve assembly 310 to move along its own axial direction relative to the outer sleeve assembly 320, and drive the limit block 330 to rotate relative to the outer sleeve assembly 320 along the first direction toward the first side wall 11. When the limit block 330 abuts against the limit groove 15, the inner sleeve assembly 310 and the outer sleeve assembly 320 are clamped and fixed, thereby switching the limit switch mechanism 300 to a locked state; after contacting the clamping connection between the inner sleeve assembly 310 and the outer sleeve assembly 320, the connecting push rod 340 moves in a direction away from the back plate 13, thereby driving the limit block 330 to rotate in a second direction and move out of the limit groove 15, thereby switching the limit switch mechanism 300 to an unlocked state. The second direction is opposite to the first direction. When the first side wall 11 is the left side wall, the first direction is counterclockwise.

[0061] Optionally, a first slide groove extending in the axial direction is provided on the outer wall of the first inner cylinder 311, and a first sliding block cooperating with the first slide groove is provided on the inner wall of the first outer cylinder 321, thereby improving the sliding properties of the first inner cylinder 311 and the first outer cylinder 321; a second slide groove extending in the axial direction is provided on the outer wall of the second inner cylinder 312, and a second sliding block cooperating with the second slide groove is provided on the inner wall of the second outer cylinder 322, thereby improving the sliding properties of the second inner cylinder 312 and the second outer cylinder 322.
[0062] Optionally, the length of the first inner cylinder 311 is smaller than that of the first outer cylinder 321 , so that the first inner cylinder 311 can move inside the first outer cylinder 321 ; the length of the second inner cylinder 312 is smaller than that of the second outer cylinder 322 , so that the second inner cylinder 312 can move inside the second outer cylinder 322 .
[0063] Optionally, a buckle 351 is provided on the first end edge 3111 of the first inner cylinder 311, and a slot 352 matching the buckle 351 is provided on the second end edge 3211 of the first outer cylinder 321. The buckle 351 and the slot 352 have simple structures, which are convenient for processing and operation. In addition, the buckle 351 and the slot 352 are arranged on the first inner cylinder 311 and the first outer cylinder 321, which is closer to the user, so that the user can manually unlock the buckle 351 and the slot 352.

When the limit switch mechanism 300 is in the unlocked state, the fifth end edge 3112 is close to the sixth end edge 3212. When the limit switch mechanism 300 needs to be switched to the locked state, the connecting push rod 340 is pushed to drive the first inner cylinder 311 to slide relative to the first outer cylinder 321 until the first end edge 3111 is flush with the second end edge 3211. At this time, the buckle 351 is automatically snapped into the slot 352. At the same time, the second inner cylinder 312 slides relative to the second outer cylinder 322 and drives the limit collar 323 to rotate, so that the limit block 330 rotates along the first direction, that is, rotates toward the limit groove 15. When the buckle 351 is snapped into the slot 352, the limit block 330 is snapped into the limit groove 15.
[0065] When it is necessary to switch the limit switching mechanism 300 to the unlocked state, since the claw of the buckle 351 is facing the user, the buckle 351 can be manually pushed to release the buckle 351 from the locking state with the slot 352. Further, pulling the connecting push rod 340 can drive the first inner cylinder 311 and the second inner cylinder 312 to slide in the direction away from the back plate 13, thereby driving the limit ring 323 to rotate, so that the limit block 330 rotates in the second direction, that is, away from the limit groove 15. When the limit block 330 is disengaged from the limit groove 15, the limit switching mechanism 300 is switched to the unlocked state, and the user can freely take the shelf body.
[0066] Optionally, the first outer cylinder 321 is fixedly connected to the shelf body 200 through at least two connecting rods, and the second outer cylinder 322 is fixedly connected to the shelf body 200 through at least two connecting rods, so that the stability of the connection between the limit switching mechanism 300 and the shelf body 200 can be ensured.
[0067] Optionally, the limiting collar 323 is disposed at a middle position on the axis of the second outer cylinder 322 , which can improve the structural symmetry and stability of the second outer cylinder 322 .
[0068] Optionally, the outer side wall of the second outer cylinder 322 is provided with two extended side walls spaced apart along the axial direction thereof, and a mounting groove is formed between the extended side walls to facilitate stable mounting of the limiting collar 323 .
[0069] Optionally, the buckle 351 has a guide slope, which is used to abut against the slot 352. By setting the side where the buckle 351 abuts against the slot 352 as an inclined guide slope, when the buckle 351 is disengaged from the slot 352, it is beneficial for the buckle 351 to leave the slot 352 along the guide slope to achieve a disengagement effect.
[0070] Optionally, combined Figure 6 , Figure 7 As shown, the second inner cylinder 312 includes a third end edge 3121 and a fourth end edge 3122, and the third end edge 3121 is close to the first inner cylinder 311; the shelf also includes a first guide assembly for limiting the motion track of the limit block 330, and the first guide assembly includes a guide rail 410 and a guide slide bar 420. The guide rail 410 is spirally opened on the outer wall of the second inner cylinder 312 from the third end edge 3121 to the fourth end edge 3122, in a direction away from the first side wall 11 or the second side wall 12; the guide slide bar 420 is arranged on the inner ring side wall of the limit collar 323 and extends along the second diameter of the limit collar 323, and the guide rail 410 and the guide slide bar 420 are slidably matched, wherein the first diameter is perpendicular to the second diameter; in the locked state, the guide slide bar 420 is located at the third end edge 3121; in the unlocked state, the guide slide bar 420 is located at the fourth end edge 3122.
[0071] That is, the end of the guide rail 410 located at the third end edge 3121 is close to the first side wall 11. Optionally, the end of the guide rail 410 located at the third end edge 3121 is located in the diameter direction of the second inner cylinder 312 extending vertically, and the end of the guide rail 410 located at the fourth end edge 3122 is located in the diameter direction of the second inner cylinder 312 extending horizontally. In this way, in the locked state, the guide slide bar 420 is located at the third end edge 3121, and the limit block 330 faces the first side wall 11 and is stuck in the limit groove 15; in the unlocked state, the guide slide bar 420 is located at the fourth end edge 3122, and the limit block 330 faces upward vertically.
[0072] When the limit switch mechanism 300 needs to be switched to the locked state, the connecting push rod 340 is pushed, thereby driving the first inner cylinder 311 to slide relative to the first outer cylinder 321 until the first end edge 3111 is flush with the second end edge 3211, and the buckle 351 is automatically locked in the locking groove 352. At the same time, the second inner cylinder 312 slides relative to the second outer cylinder 322 toward the back plate 13. Due to the movement of the second inner cylinder 312, the guide rail 410 moves, thereby forcing the guide slide bar 420 located in the guide rail 410 to move relatively along the guide rail 410. In the process of the guide rail 410 moving from the fourth end edge 3122 to the third end edge 3121, the limit collar 323 is driven to rotate, so that the limit block 330 rotates toward the first side wall 11, that is, toward the limit groove 15. When the buckle 351 is locked in the locking slot 352 , the limiting block 330 is locked in the limiting groove 15 .
[0073] When it is necessary to switch the limit switching mechanism 300 to the unlocked state, the buckle 351 is disengaged from the slot 352, and the second inner cylinder 312 slides relative to the second outer cylinder 322 in the direction away from the back plate 13. Due to the movement of the second inner cylinder 312, the guide rail 410 moves, thereby forcing the guide slide bar 420 located in the guide rail 410 to move relatively along the guide rail 410. In the process of the guide rail 410 moving from the third end edge 3121 contacting the guide slide bar 420 to the fourth end edge 3122 contacting the guide slide bar 420, the limit collar 323 is driven to rotate, so that the limit block 330 rotates away from the first side wall 11 until the limit block 330 is separated from the limit groove 15.
[0074] Optionally, a stopper is provided at the end of the guide rail 410. That is, a stopper is provided at the end of the guide rail 410 located at the third end edge 3121 and the end of the guide rail 410 located at the fourth end edge 3122. When the guide slide bar 420 moves to the third end edge 3121 or the fourth end edge 3122, it abuts against the stopper to prevent the guide slide bar 420 from falling out of the guide rail 410, thereby improving the stability of the limit switching mechanism.
[0075] Optionally, combined Figure 8 As shown, the shelf further includes a second guide assembly for defining a rotation track of the guide slide bar 420, and the second guide assembly includes a second guide rail 430. The second guide rail 430 is arranged along the circumference of the second outer cylinder 322 and penetrates the side wall of the second outer cylinder 322, so that the guide slide bar 420 can pass through the second outer cylinder 322 and be slidably connected to the guide rail 410.
[0076] The provision of the second guide rail 430 is conducive to ensuring the rotational movement of the guide slide bar 420 relative to the second inner cylinder 312 when the second inner cylinder 312 moves relative to the second outer cylinder 322 .
[0077] Optionally, combined Figure 6 , Figure 7 As shown, a sealing plate 324 is provided on the side of the second outer cylinder 322 facing away from the first outer cylinder 321; the outer cylinder assembly 320 further includes an elastic member 325. The elastic member 325 is sleeved on the outer periphery of the connecting push rod 340 and is located between the second inner cylinder 312 and the sealing plate 324, wherein the sealing plate 324 is provided with a through hole 3241 for the connecting push rod 340 to extend out.
[0078] Optionally, a support plate is sleeved on the connecting push rod 340 , so that one end of the elastic member 325 is fixed to the support plate, and the other end is fixedly connected to the sealing plate 324 , so as to facilitate the fixation of the elastic member 325 .
[0079] Thus, when the limit switch mechanism 300 is in the locked state, the elastic member 325 is compressed and stores elastic force. When the buckle 351 is disengaged from the slot 352, the elastic member 325 can release the elastic force to push the connecting push rod 340 to move away from the back plate 13, so as to drive the limit switch mechanism to switch to the unlocked state, saving time and effort.
