The first chuck surface abuts against any of the gear teeth at the limiting position; the second chuck surface is disposed opposite to the first chuck surface, and the second chuck surface and the first chuck surface are arranged sequentially along the direction in which the shelf is pulled and the rotating wheel is rotated; wherein, the second chuck surface is provided with a first guide slope, and the gear teeth drive the first guide slope to move, so as to drive the chuck to move in the direction of disengaging from the gear teeth.

[0011] In some embodiments, there are multiple locking components, including a first locking component and a second locking component located on the same side of the shelf. The number of the rotating wheels is equal to the number of the locking components and corresponds one-to-one. The multiple rotating wheels include a first rotating wheel that cooperates with the first locking component and a second rotating wheel that cooperates with the second locking component. The first locking component and the second locking component are disposed between the first rotating wheel and the second rotating wheel, and are arranged sequentially along the rotation direction of the rotating wheels driven by the shelf.

[0012] In some embodiments, the gear teeth are elastic gear teeth, and the engaging assembly includes a locking plate with claw grooves; the elastic gear teeth engage with or disengage from the claw grooves to allow the engaging assembly to switch between the limiting position and the disengaging position.

[0013] In some embodiments, the elastic gear tooth includes: a first connecting portion, a second connecting portion, and a locking portion. The first connecting portion is connected to the rotating wheel; one end of the second connecting portion is connected to the first connecting portion and the connection point forms an angle; the locking portion is disposed at the other end of the second connecting portion, and at the limiting position, the locking portion engages with the claw groove.

[0014] In some embodiments, the engaging portion includes a first sidewall and a second sidewall disposed opposite to each other, and the first sidewall and the second sidewall are arranged sequentially along the rotation direction of the shelf driving the rotating wheel; along the rotation direction of the shelf driving the rotating wheel, the second sidewall is inclined toward the rotation center of the rotating wheel where the second sidewall is located to form a second guide slope, and the claw groove is provided with a third guide slope that is adapted to the second guide slope.

[0015] In some embodiments, the shelf further includes a side panel with an opening, and the caster is located within the opening and is rotatable relative to the opening.

[0016] The second aspect of the present invention provides a refrigerator, including the shelf as described in the above embodiments.

[0017] In some embodiments, the refrigerator includes an inner liner and side panels embedded in the inner liner.

[0018] The shelves and refrigerators provided in this disclosure can achieve the following technical effects:

[0019] The shelf is connected to the casters. When using the shelf, pulling the shelf moves the casters, whose teeth engage with a locking mechanism. The locking mechanism sometimes abuts against the teeth and sometimes disengages. When the locking mechanism abuts against the teeth, the shelf is fixed in place; when it disengages, the shelf's height can be adjusted. Thus, simply pulling the shelf allows it to be adjusted to multiple height positions, accommodating items of different sizes and heights, making operation simple and convenient.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0039] Combination Figure 1 As shown, this embodiment of the present disclosure provides a shelf, including a locking assembly 1, a rotating wheel 2, and a shelf 4. The rotating wheel 2 corresponds to the locking assembly 1 and can rotate relative to the locking assembly 1 around its own rotation center. The rotating wheel 2 has multiple teeth 3, which are located on the same circumference with the rotation center as the center. The teeth 3 are elastic teeth 3 and / or the locking assembly 1 is an elastic locking assembly 1, so that the locking assembly 1 can switch between a limited position and a disengaged position that is disengaged from the teeth 3. In the limited position, the locking assembly 1 abuts against any tooth 3 to restrict the tooth 3 from continuing to move. The shelf 4 is connected to the non-rotation center position of the rotating wheel 2. Pulling the shelf 4 causes the rotating wheel 2 to rotate relative to the locking assembly 1 around its rotation center.

[0040] The shelf provided in this embodiment has a shelf panel 4 connected to a rotating wheel 2. When using the shelf, pulling the shelf panel 4 causes it to move the rotating wheel 2. The gear teeth 3 of the rotating wheel 2 engage with the engaging component 1. The engaging component 1 sometimes abuts against the gear teeth 3 and sometimes disengages from them. When the engaging component 1 abuts against the gear teeth 3, the shelf panel 4 is fixed. When the engaging component 1 disengages from the gear teeth 3, the shelf panel 4 can be adjusted in height. Thus, by simply pulling the shelf panel 4, it can be adjusted to multiple height positions to accommodate items of different sizes and heights, making operation simple and convenient.

[0041] Optionally, combined Figure 2As shown, the engaging assembly 1 is an elastic engaging assembly 1, which includes a jaw 101 and an elastic element 102. The jaw 101 can abut against any tooth 3 in the limiting position and disengage from any tooth 3 in the disengagement position; the elastic element 102 is connected to the jaw 101, and when the jaw 101 disengages from any tooth 3, the elastic element 102 undergoes elastic deformation to drive the jaw 101 back to the limiting position.

[0042] A spring can be selected as the elastic element 102. The elastic element 102 is connected to the claw 101, so that the engaging assembly 1 can extend and retract.

[0043] When the locking component 1 extends and the pawl 101 abuts against any of the wheel teeth 3, the locking component 1 is in a limited position, restricting the rotation of the wheel 2. At this time, the height of the shelf 4 is fixed.

[0044] When the locking assembly contracts, the pawl 101 disengages from the gear tooth 3, the locking assembly 1 is in the disengaged position, the wheel 2 can rotate, and the height of the shelf 4 can be adjusted at this time.

[0045] In this way, when the locking component 1 is an elastic locking component 1, the height of the shelf 4 can be adjusted.

[0046] Optionally, combined Figure 2 As shown, the chuck 101 includes a first chuck surface 1011 and a second chuck surface 1012. The first chuck surface 1011 abuts against any of the gear teeth 3 at a limiting position; the second chuck surface 1012 is arranged opposite to the first chuck surface 1011, and the second chuck surface 1012 and the first chuck surface 1011 are arranged sequentially along the direction in which the pull plate 4 drives the rotating wheel 2 to rotate; wherein, the second chuck surface 1012 is provided with a first guide inclined surface 10121, and the gear teeth 3 drive the first guide inclined surface 10121 to move, so as to drive the chuck 101 to move in the direction of disengaging from the gear teeth 3.

[0047] Along the direction in which the pull shelf 4 drives the rotating wheel 2 to rotate, the second claw surface 1012 and the first claw surface 1011 are arranged in sequence, and the second claw surface 1012 is provided with a first guide slope 10121.

[0048] Pull the shelf 4, and the shelf 4 will drive the rotating wheel 2 to rotate around its own rotation center. After the wheel tooth 3 contacts the first guide slope 10121, it will apply force to the first guide slope 10121. The pawl 101 and the elastic element 102 will retract under the force. At this time, the pawl 101 will disengage from the wheel tooth 3.

[0049] Next, the elastic element 102 undergoes elastic deformation and rebounds, and the claw 101 extends under the action of the elastic element 102, so that the engaging assembly 1 is in a limited position, restricting the rotation of the rotating wheel 2.

[0050] In this way, the claw 101 cooperates with the wheel 2 under the action of the elastic force of the elastic element 102, so that the wheel 2 is suspended at each position, thereby controlling the height of the shelf 4 and making the shelf have multiple adjustable positions.

[0051] Optionally, combined Figure 2 As shown, there are multiple locking components 1, including a first locking component 11 and a second locking component 12 located on the same side of the shelf. The number of rotating wheels 2 is equal to the number of locking components 1 and corresponds one-to-one. The multiple rotating wheels 2 include a first rotating wheel 21 that cooperates with the first locking component 11 and a second rotating wheel 22 that cooperates with the second locking component 12. The first locking component 11 and the second locking component 12 are located between the first rotating wheel 21 and the second rotating wheel 22, and are arranged sequentially along the rotation direction of the rotating wheels 2 driven by the shelf 4.

[0052] The first rotating wheel 21 cooperates with the first engaging component 11, and the second rotating wheel 22 cooperates with the second engaging component 12. The first engaging component 11 and the second engaging component 12 are located between the first rotating wheel 21 and the second rotating wheel 22. Thus, the layout on the same side is: the first rotating wheel 21, the first engaging component 11, the second engaging component 12 and the second rotating wheel 22.

[0053] The first engaging assembly 11 and the second engaging assembly 12 are arranged sequentially along the rotation direction of the rotating wheel 2 driven by the shelf 4.

[0054] In this way, when the shelf is pulled, the first locking assembly 11 and the second locking assembly 12 extend and retract synchronously, preventing the rotating wheel 2 from reversing, thus ensuring that the first rotating wheel 21 and the second rotating wheel 22 rotate synchronously in the same direction. As a result, the shelf 4 can always maintain a horizontal translational state when its height is adjusted.

[0055] Optionally, combined Figure 3 As shown, the gear tooth 3 is an elastic gear tooth 3, and the engaging assembly 1 includes a locking plate 111, on which a claw groove 1111 is provided; the elastic gear tooth 3 engages with the claw groove 1111 or disengages from the claw groove 1111 so that the engaging assembly 1 switches between a limiting position and a disengaged position.

[0056] The elastic tooth 3 engages with the claw groove 1111, and the engaging component 1 is in the limiting position, restricting the rotation of the rotating wheel 2. At this time, the height of the shelf 4 is fixed.

[0057] The elastic tooth 3 disengages from the claw groove 1111, the engaging assembly 1 is in the disengaged position, the rotating wheel 2 can rotate, and the height of the shelf 4 can be adjusted at this time.

[0058] In this way, when the gear tooth 3 is an elastic gear tooth 3, the height of the shelf 4 can be adjusted.

[0059] Optionally, combined Figure 3As shown, the elastic gear tooth 3 includes a first connecting part 31, a second connecting part 32, and a locking part 33. The first connecting part 31 is connected to the rotating wheel 2; one end of the second connecting part 32 is connected to the first connecting part 31 and the connection point forms an angle 34; the locking part 33 is provided at the other end of the second connecting part 32, and in the limiting position, the locking part 33 is engaged in the claw groove 1111.

[0060] The first connecting part 31, the second connecting part 32, and the engaging part 33 of the elastic gear tooth 3 are all made of elastic material.

[0061] Pulling the shelf 4 causes the engaging part 33 to deform elastically under force and disengage from the claw groove 1111, putting the engaging assembly 1 in the disengaged position, allowing the rotating wheel 2 to rotate.

[0062] When the engaging part 33 reaches the next claw groove 1111, the engaging part 33 elastically deforms and engages into the claw groove 1111, so that the engaging assembly 1 is in the limited position and the height of the shelf 4 no longer changes.

[0063] In this way, the engaging part 33 of the elastic tooth 3 engages with the claw groove 1111, causing the rotating wheel 2 to hover at each position, thereby controlling the height of the shelf 4 and giving the shelf multiple adjustable positions.

[0064] Optionally, combined Figure 3 As shown, the engaging part 33 includes a first sidewall 331 and a second sidewall 332 arranged opposite to each other, and the first sidewall 331 and the second sidewall 332 are arranged sequentially along the rotation direction of the shelf 4 driving the rotating wheel 2; along the rotation direction of the shelf 4 driving the rotating wheel 2, the second sidewall 332 is inclined toward the rotation center of the rotating wheel 2 where the second sidewall 332 is located to form a second guide slope 3321, and the claw groove 1111 is provided with a third guide slope 3322 that is adapted to the second guide slope 3321.

[0065] The third guide slope 3322 is adapted to the second guide slope 3321, and the third guide slope 3322 is adapted to the second sidewall 332. The claw groove 1111 is adapted to the engaging part 33. The second guide slope 3321 is formed by tilting towards the rotation center of the rotating wheel 2 where the second sidewall 332 is located. Therefore, the third guide slope 3322 is tilted towards the rotation center of the rotating wheel 2 where the second sidewall 332 is located. In this way, as the rotating wheel 2 rotates, the engaging part 33 of the gear tooth 3 can more easily disengage from the claw groove 1111.

[0066] Optionally, the number of claw grooves 1111 is equal to the number of gear teeth 3 and corresponds one-to-one.

[0067] In this way, when in the limit position, each tooth 3 can be engaged in the claw groove 1111, and the wheel 2 can stay stably in the limit position, increasing the reliability of the shelf.

[0068] Optionally, combined Figures 1 to 3As shown, the shelf also includes a side panel 5, which has an opening 51. The swivel wheel 2 is located inside the opening 51 and can rotate relative to the opening 51.

[0069] The side plate 5 has an opening 51, and the rotating wheel 2 is located inside the opening 51, that is, the rotating wheel 2 is embedded in the side plate 5 and can rotate inside the opening 51.

[0070] When the engaging component 1 is an elastic engaging component 1, the side plate 5 is provided with a guide groove 7, and the elastic engaging component 1 is fixed in the guide groove 7.

[0071] In this way, the side panel 5 makes the entire shelf structure more stable. The shelf can be placed on the countertop for use, or it can be installed in the refrigerator, wardrobe, etc.

[0072] Optionally, combined Figure 1 , Figure 3 and Figure 4 As shown, the non-rotation center position of the rotating wheel 2 is provided with one of the protrusions 8 or the groove 9, and the shelf 4 is provided with the other of the protrusions 8 or the groove 9. The protrusions 8 and the groove 9 cooperate to connect the rotating wheel 2 and the shelf 4.

[0073] Taking the non-rotation center position of the rotating wheel 2 as an example, the shelf 4 is provided with a groove 9. The protrusion 8 and the groove 9 cooperate to fix the shelf 4 on the rotating wheel 2.

[0074] When using the shelf, pull the shelf 4, which will cause the wheel 2 to rotate. The height of the shelf 4 can also change as the wheel 2 rotates.

[0075] Optionally, combined Figure 1 As shown, the shelf 4 has multiple curved surfaces 10.

[0076] In this way, shelf 4 can hold not only normally shaped items, but also bottled beverages such as wine. Bottled items placed on the curved surface 10 will not roll, making it convenient for storing drinks.

[0077] This disclosure provides a refrigerator that, having the shelves of any of the foregoing embodiments, possesses all the beneficial effects of the shelves of any of the foregoing embodiments, which will not be repeated here.

[0078] Optionally, combined Figure 5 and Figure 6 As shown, the refrigerator includes an inner liner 6 and a side panel 5 embedded in the inner liner 6.

[0079] The side panel 5 of the shelf is designed to be embedded in the refrigerator liner 6. The side panel 5 and the liner 6 together form a complete cavity, and the swivel wheel 2 and the locking assembly 1 are housed inside the cavity.

[0080] In this way, the side panel 5 has high support strength, and the side panel 5, the roller 2 and the elastic component are not visible from the outside. Only the shelf 4 is visible, which looks neat. Furthermore, the side panel 5 is embedded in the inner liner 6, which can increase the usable space of the refrigerator.
