Abstract
Description
Technical Field
[0001] This application relates to the field of refrigerator technology, and more particularly to a shelf and a refrigerator. Background Technology
[0002] Refrigerators typically have multiple shelves inside to maximize the utilization of storage space. These shelves are usually height-adjustable, allowing for adjustments to the upper shelf space to accommodate items of varying sizes.
[0003] In the prior art, in order to adjust the height of the shelves, the inner wall of the refrigerator is generally provided with multiple insertion grooves of different heights. When adjusting the height of the shelves, the items on the shelves need to be removed first, the shelves need to be pulled out from the insertion grooves of the original height, and then the shelves need to be inserted into the insertion grooves of another height to complete the height adjustment of the shelves.
[0004] It is evident that adjusting the height of the existing shelves is cumbersome. Summary of the Invention

[0012] The sliding member and the rotating member are provided with a guide groove, and the other member is provided with a guide post that cooperates with the guide groove.
[0013] The sliding member is provided with the guide groove;
[0014] The slider includes a first extension and a second extension. One end of the first extension and the second extension are both connected to the first protruding end. The first extension, the second extension, and the first protruding end form the guide groove. The other end of the first extension forms the second protruding end. There is a gap between the other end of the second extension and the first extension.
[0015] The shelf body and the sliding member are provided with a guide hole, and the other is provided with a guide post that cooperates with the guide hole.
[0016] The rotating component has a first state and a second state. The sliding component is used to control the rotating component to switch between the first state and the second state. In the first state, the rotating component is used to prevent the support portion from entering the first slide rail from the connection between the first slide rail and the second slide rail. In the second state, the rotating component is used to prevent the support portion from entering the second slide rail from the connection between the first slide rail and the second slide rail.
[0017] The shelf also includes:
[0018] An elastic element is disposed between the sliding element and the shelf body, for positioning the rotating element in the first state by the sliding element.
[0019] The rotating component has a first limiting surface and a second limiting surface. The first limiting surface is used to cooperate with the side wall of the first slide when the rotating component is in the first state.

[0024] Any shelf as described above is disposed within the storage cavity, and the support portion is embedded in the first or second slide rail of the shelf.
[0025] The beneficial effects of the embodiments of this application are as follows: This application provides a shelf, which is applied to a storage device, and the storage device is provided with a support. The shelf includes a shelf body, a rotating member, and a sliding member. The shelf body is provided with a first slide rail and a second slide rail. One end of the first slide rail and the second slide rail are connected to each other, and the other end is connected through a slide groove. The first slide rail extends obliquely upward from the connection point with the second slide rail, and the second slide rail extends obliquely downward from the connection point with the first slide rail. The rotating member is rotatably disposed on the shelf body. The sliding member is slidably disposed in the slide groove. The sliding member is used to control the rotation of the rotating member. In a first state, the rotating member is used to prevent the support from entering the first slide rail from the second end. In a second state, the rotating member is used to prevent the support from entering the second slide rail from the third end. The sliding member has a first protruding end and a second protruding end. The first protruding end is used to cooperate with the support in the second slide rail to move the sliding member. The second protruding end forms a snap-fit structure. The snap-fit structure is used to cooperate with the shelf body. The snap-fit structure includes a first guide surface. The first guide surface is used to cooperate with the support part in the first slide rail to disengage the snap-fit structure from the shelf body. The shelf provided in this application, by providing a first slide rail and a second slide rail on the shelf body, allows the shelf to be slidably mounted on the storage device by cooperating with the support part on the storage device to be used. Since one end of the first slide rail and the second slide rail are connected, the support part can slide between the first and second slide rails by pushing and pulling the shelf. Because the first slide rail extends upward at an angle from its connection point with the second slide rail, and the second slide rail extends downward at an angle from its connection point with the first slide rail, with the first slide rail having a high end and the second slide rail having a low end, the height of the shelf can be adjusted by switching the support part between the high end of the first slide rail and the low end of the second slide rail. It is evident that the shelf provided in this application only requires pushing and pulling the shelf to adjust its height during the entire adjustment process. Compared to the prior art, which involves pulling the shelf out of the original height's insertion groove and then inserting it into the insertion groove of another height, this effectively simplifies the shelf adjustment operation.

[0037] Please see Figure 1 , Figure 1 This is a structural schematic diagram of the shelf provided in this application applied to a refrigerator. This application provides a shelf. The shelf 100 can be applied to storage devices. The storage device can be a refrigerator 1000, a cupboard, or a display rack, etc., but is not limited to these.
[0038] Please refer to the following: Figures 2 to 3 , Figure 2 This is a schematic diagram of the structure of the shelf provided in this application, with the first slide rail and the second slide rail on one side and the support part located at the first end. Figure 3This is a schematic diagram of the shelf provided in this application, showing one side with the first and second slide rails and the support portion located at the fourth end. The shelf 100 is used in a storage device, which has a support portion 201 for supporting the shelf 100. The shelf 100 includes a shelf body 10, a rotating member 20, and a sliding member 30. The shelf body 10 has a first slide rail 11 and a second slide rail 12. The first slide rail 11 and the second slide rail 12 are used to cooperate with the support portion 201 on the storage device. One end of the first slide rail 11 and the second slide rail 12 are connected to each other, and the other end is connected through a slide groove 15. The first slide rail 11 extends obliquely upward from the connection with the second slide rail 12, and the second slide rail 12 extends obliquely downward from the connection with the first slide rail 11. The rotating member 20 is rotatably disposed in the slide groove 15. The sliding member 30 is slidably disposed on the shelf body 10. The sliding member 30 is used to control the rotation of the rotating member 20. The sliding member 30 has a first protruding end 33 and a second protruding end 311. The first protruding end 33 is used to cooperate with the support portion 201 in the second slide rail 12 to move the sliding member 30. The second protruding end 311 forms a snap-fit structure. The snap-fit structure is used to cooperate with the shelf body 10, and the snap-fit mechanism includes a first guide surface 311a. The first guide surface 311a is used to cooperate with the support portion 201 in the first slide rail 11 to disengage the snap-fit mechanism from the shelf body 10.
[0039] The shelf body 10 is primarily used to support items. This application does not limit the specific structure of the shelf body 10. In some embodiments, the shelf body 10 may include a loading plate 151 and side plates 152. There are two side plates 152. The side plates 152 are disposed on opposite sides of the loading plate 151. The loading plate 151 is used to load items. The side plates 152 cooperate with the support portion 201 on the storage device to support the loading plate 151. The first slide rail 11 and the second slide rail 12 on the shelf body 10 may be formed on the side plates 152. When the shelf 100 is applied in a storage device, with the loading plate 151 horizontal and the two side plates 152 vertical, the support portion 201 may be disposed on opposite side walls of the storage device to cooperate with the first slide rail 11 and the second slide rail 12 on the side plates 152.
[0040] This application does not limit the specific mating structure between the support portion 201 and the first slide rail 11 and the second slide rail 12. In some embodiments, the first slide rail 11 and the second slide rail 12 can be a groove 15 provided on the side plate 152, and the support portion 201 can be a support shaft that mates with the groove 15, with the end of the support shaft embedded in the groove 15. The support shaft can be fixedly provided on the side wall of the storage device or rotatably provided on the side wall of the storage device. To reduce the friction between the support portion 201 and the first slide rail 11 and the second slide rail 12, when the support portion 201 is fixedly provided on the side wall of the storage device, a roller can be provided at the end of the support portion 201. When the support portion 201 slides along the first slide rail 11 and the second slide rail 12, the roller rolls along the side wall of the first slide rail 11 and the second slide rail 12.
[0041] It should be noted that the first slide rail 11 has a first end 111 and a second end 112. The second slide rail 12 has a third end 121 and a fourth end 122. The first end 111 and the third end 121 overlap, enabling communication between the first slide rail 11 and the second slide rail 12. The first end 111 and the fourth end 122 are spaced apart along the height adjustment direction of the shelf 100. The first end 111 is used to position the shelf 100 at a first height. The fourth end 122 is used to position the shelf 100 at a second height. Since the first slide rail 11 extends upward at an angle and the second slide rail 12 extends downward at an angle, the first height is higher than the second height. The second end 112 of the first slide rail 11 overlaps with the third end 121 of the second slide rail 12. It should be understood that the second end 112 of the first slide rail 11 and the third end 121 of the second slide rail 12 share the same end slot; that is, in the height adjustment direction of the shelf 100, the second end 112 of the first slide rail 11 and the third end 121 of the second slide rail 12 are at the same height. The first end 111 of the first slide rail 11 and the fourth end 122 of the second slide rail 12 are spaced apart in the height adjustment direction of the shelf 100. It should be understood that the first end 111 of the first slide rail 11 and the fourth end 122 of the second slide rail 12 are at different heights in the height adjustment direction of the shelf 100.
[0042] Since both the first slide rail 11 and the second slide rail 12 extend at an angle, when the shelf 100 is adjusted from a low position to a high position, the support part 201 moves along the inclined slide rail, making pushing and pulling easier. This application does not limit the specific inclination angle of the first slide rail 11 and the second slide rail 12. Let G be the total weight of the shelf 100 and the items on it, X be the inclination angle of the first slide rail 11 and the second slide rail 12, μ be the coefficient of rolling friction between the support part 201 and the first slide rail 11 and the second slide rail 12, and F be the pushing and pulling force when adjusting the shelf 100 from a low position to a high position. Then F = G(μ + tanX) / (1 - μtanX). It can be seen that the smaller the inclination angle of the first slide rail 11 and the second slide rail 12, the less effort the user needs to exert when pushing and pulling the shelf 100. Specifically, the design can be based on the adjustable height of the shelf 100 and the horizontal dimensions of the side panel 152.
[0043] Please refer to the following: Figure 4 , Figure 4 This is a schematic diagram of the structure of a shelf 100 provided in another embodiment of this application, on one side where the first slide rail 11 and the second slide rail 12 are provided. Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 The first slide 11 and the second slide 12 with two different tilt angles are shown. Figure 3 neutralization Figure 4 The height adjustment of the middle shelf 100 is the same, and the setting is... Figure 3 and Figure 4 The height of the middle shelf 100 is adjustable by 6cm. Figure 3 The inclination angle of the first slide 11 and the second slide 12 is 24.3°. Figure 4 The inclination angle of the first slide 11 and the second slide 12 is 13.5°, which is obvious. Figure 4 The shelf 100 in the middle is easier to adjust from the low position to the high position.
[0044] like Figures 2 to 4As shown, in some embodiments, to ensure the stability of the shelf 100 during the pushing and pulling process, a third slide rail 161 and a fourth slide rail 162 may be provided on the side plate 152 of the shelf body 10. One end of the third slide rail 161 overlaps with one end of the fourth slide rail 162, and the other ends of the third slide rail 161 and the other ends of the fourth slide rail 162 are spaced apart along the height adjustment direction of the shelf 100. It should be understood that when the side plate 152 of the shelf body 10 is also provided with a third slide rail 161 and a fourth slide rail 162, two support parts 201 should be provided on each side wall of the storage device that cooperates with the side plate 152. One support part 201 cooperates with the first slide rail 11 and the second slide rail 12, and the other support part 201 cooperates with the third slide rail 161 and the fourth slide rail 162. In addition, it should be understood that the third slide rail 161 and the fourth slide rail 162 may also be provided with a rotating member 20 and a sliding member 30 respectively. Figure 2 and Figure 3 The rotating component 20 and sliding component 30 corresponding to the third slide rail 161 and the fourth slide rail 162 are not shown.
[0045] like Figure 4 As shown, in some embodiments, to ensure that the support part 201 can stably support the shelf 100 when the shelf 100 is in a high position, the fourth end 122 of the second slide rail 12 is also provided with a locking groove 124. After the support part 201 slides to the fourth end 122 of the second slide rail 12, it enters the locking groove 124 and cooperates with the locking groove 124. When the storage device on which the shelf 100 is used is shaken by external force or when the user takes or puts items from the shelf 100, the shelf 100 may be subjected to an outward pulling force, thereby detaching from the fourth end 122 and sliding towards the third end 121. The locking groove 124 can prevent the support part 201 from detaching from the fourth end 122. It should be noted that when the fourth end 122 of the second slide rail 12 is provided with a locking groove 124, when adjusting the shelf 100 from the high position to the low position, the shelf 100 needs to be lifted slightly upwards first so that the support part 201 disengages from the locking groove 124, and then the shelf 100 is pulled so that the support part 201 slides from the fourth end 122 of the second slide rail 12 to the third end 121.
[0046] The rotating member 20 is rotatably mounted on the shelf body 10. The rotating member 20 has a first state and a second state. The sliding member 30 controls the rotation of the rotating member 20, i.e., controls the switching of the rotating member 20 between the first and second states. When the rotating member 20 rotates to the first state, it prevents the support part 201 from entering the first slide rail 11 from the connection between the first slide rail 11 and the second slide rail 12, that is, prevents the support part 201 from entering the first slide rail 11 from the second end 112. Figure 2 As shown; when rotated to the second state, it prevents the support part 201 from entering the second slide 12 from the connection between the first slide 11 and the second slide 12, that is, prevents the support part 201 from entering the second slide 12 from the third end 121, as shown. Figure 3 As shown, the rotation axis of the rotating member 20 can be disposed between the first slide rail 11 and the second slide rail 12. This application does not limit the specific structure of the rotating member 20. For example, in some embodiments, the rotating member 20 may include a first rotating arm 21 and a second rotating arm 22, with the rotation axis of the rotating member 20 located between the first rotating arm 21 and the second rotating arm 22. The first rotating arm 21 is used to cooperate with the first slide rail 11 and the second slide rail 12, and the second rotating arm 22 is used to cooperate with the sliding member 30.
[0047] To prevent the support portion 201 from entering the first slide rail 11 from the second end 112 when the rotating arm is in the first state and to prevent the support portion 201 from entering the second slide rail 12 from the third end 121 when the rotating arm is in the second state, in some embodiments, the rotating member 20 has a first limiting surface 23 and a second limiting surface 24. It should be understood that both the first limiting surface 23 and the second limiting surface 24 are formed on the first rotating arm 21 of the rotating member 20. The first limiting surface 23 is used to engage with the side wall of the first slide rail 11 when the rotating member 20 is in the first state. When the support portion 201 slides from the second end 112 toward the first slide rail 11, it will squeeze the rotating member 20, thereby causing the first limiting surface 23 to press tightly against the side wall of the first slide rail 11 and preventing the rotating member 20 from rotating, thus preventing the support portion 201 from entering the first slide rail 11 from the second end 112. It should be noted that when the rotating component 20 is provided with a second limiting surface 24, the side wall of the second slide rail 12 is correspondingly provided with a limiting groove 123. When the rotating component 20 is in the second state, the end of the first rotating arm 21 extends into the limiting groove 123. At the same time, the second limiting surface 24 of the rotating component 20 abuts against the side wall of the limiting groove 123. This means that the side wall of the limiting groove 123 supports the first rotating arm 21, preventing the rotating component 20 from rotating to the side facing the second limiting surface 24. When the support part 201 slides from the third end 121 to the second slide rail 12, the support part 201 squeezes the first rotating arm 21 but cannot push the rotating component 20 to rotate, thereby preventing the support part 201 from entering the second slide rail 12 from the third end 121.
[0048] Please refer to the following: Figure 5 , Figure 5 yes Figure 3Enlarged view at point A. The slider 30 is slidably disposed in the slide groove 15, and the slide groove 15 communicates with the first slide rail 11 and the second slide rail 12. The slider 30 has a first protruding end 33 and a second protruding end 311. The first protruding end 33 is used to cooperate with the support portion 201 in the second slide rail 12 to move the slider 30. That is, when the first protruding end 33 protrudes into the second slide rail 12, when the support portion 201 moves in the second slide rail 12, the support portion 201 can press the slider 30 by cooperating with the first protruding end 33, causing the slider 30 to move along the slide groove 15. To enable the support portion 201 to drive the slider 30 to move when cooperating with the first protruding end 33, the first protruding end 33 can be provided with a second guide surface 331. The second guide surface 331 can be an arc-shaped surface or include two inclined surfaces, one of which faces the fourth end 122, and the other inclined surface faces the third end 121. The first guide surface 311a of the second protruding end 311 is used to cooperate with the support part 201 in the first slide rail 11 to disengage the snap-fit structure from the shelf body 10. That is, when the first protruding end 33 protrudes into the first slide rail 11, when the support part 201 moves in the first slide rail 11, the support part 201 can squeeze the snap-fit structure by cooperating with the first guide surface 311a, thereby disengaging the snap-fit structure from the shelf body 10. It should be noted that the sliding member 30 is slidably disposed on the shelf body 10, having a first position when the first protruding end 33 protrudes into the second slide rail 12, and a second position when the second protruding end 311 protrudes into the first slide rail 11. The sliding member 30 controls the rotating member 20 to switch between a first state and a second state by switching between the first position and the second position. This application uses the example of the sliding member 30 being in the first position and the corresponding control of the rotating member 20 to be in the first state, and the sliding member 30 being in the second position and the corresponding control of the rotating member 20 to be in the second state, to illustrate this.
[0049] When the snap-fit structure protrudes into the first slide rail 11, it engages with the shelf body 10 to hold the sliding member 30 in the second position. This application does not limit the specific structure of the snap-fit structure at the second protruding end 311. In some embodiments, the snap-fit structure may further include an overlapping surface 311b, which, along with the first guide surface 311a, forms a triangular protrusion. Correspondingly, the shelf body 10 is provided with a support surface 13 that engages with the overlapping surface 311b. When the sliding member 30 is in the second position, the support portion 201 engages with the second protruding end 311 of the sliding member 30 to drive the sliding member 30 to move. The overlapping surface 311b of the snap-fit structure moves from below the support surface 13 to above it, thereby engaging with the support surface 13 to hold the sliding member 30 in the second position. When the slider 30 is in the second position, the first guide surface 311a protrudes into the first slide rail 11. When the support part 201 cooperates with the first guide surface 311a, the support part 201 can squeeze the first guide surface 311a to make the overlapping surface 311b and the support surface 13 move relative to each other until the overlapping surface 311b and the support surface 13 disengage. Then the slider 30 can return to the first position under the action of gravity or the elastic force of the elastic member 40, thereby realizing the switching of the slider 30 between the first position and the second position.
[0050] To ensure that the sliding member 30 can drive the rotating member 20 from the second state to the first state during the process of switching from the second position to the first position, in some embodiments, the shelf 100 further includes an elastic member 40. The elastic member 40 is disposed between the sliding member 30 and the shelf body 10. The elastic member 40 is used to position the rotating member 20 in the first state by the sliding member 30, that is, to return the sliding member 30 to the first position. The elastic member 40 can be a spring. This application does not limit the specific arrangement structure of the elastic member 40 on the shelf 100. For example, in some embodiments, one of the shelf body 10 and the sliding member 30 is provided with a guide hole, and the other is provided with a guide post 35 that cooperates with the guide hole. This application uses the example of the shelf body 10 being provided with a guide hole and the sliding member 30 being provided with a guide post 35 for description. When the elastic member 40 is a spring, the elastic member 40 can be sleeved on the guide post 35.
[0051] The slider 30 is used to control the rotation member 20 to switch between a first state and a second state, and can cooperate with the second rotating arm 22 of the rotation member 20. This application does not limit the specific cooperation structure between the slider 30 and the second rotating arm 22. For example, one of the slider 30 and the rotation member 20 may be provided with a guide groove 34, and the other may be provided with a guide post that cooperates with the guide groove 34. When the slider 30 slides along the slide groove 15, the rotation member 20 is driven to switch between the first state and the second state through the cooperation of the guide groove 34 and the guide post.
[0052] In some embodiments, the slider 30 is provided with a guide groove 34, and the second rotating arm 22 of the rotating member 20 is provided with a guide post that cooperates with the guide groove 34. The slider 30 may include a first extension 31 and a second extension 32. The first extension 31 and the second extension 32 are both connected to a first protruding end 33, and the first extension 31, the second extension 32 and the first protruding end 33 form the guide groove 34. The other end of the first extension 31 forms a second protruding end 311, and a gap is left between the other end of the second extension 32 and the first extension 31. When the first guide surface 311a cooperates with the support 201, the support 201 can deform by pressing the first extension 31, so that the overlapping surface 311b disengages from the support surface 13. The gap between the other end of the second extension 32 and the first extension 31 can reserve space for the deformation of the first extension 31.
[0053] It should be noted that, to facilitate the sliding of the slider 30 in the slide groove 15 of the shelf body 10, the slide groove 15 can be a groove formed on the surface of the side plate 152 of the shelf body 10. To prevent the slider from disengaging from the slide groove 15, a baffle 16 can also be provided on the surface of the side plate 152.
[0054] The following example illustrates the adjustment process of the shelf 100, with the first end 111 of the first slide rail 11 being higher than the fourth end 122 of the second slide rail 12, and the loading plate 151 of the shelf body 10 being connected to the side plate 152 near the end of the first slide rail 11:
[0055] like Figure 2 As shown, when the support 201 is located at the first end 111 of the first slide rail 11, the shelf 100 is positioned at the first height and is in a low position. When the shelf 100 is in the low position, the slider 30 is in the first position. Under the action of the elastic member 40, the first protruding end 33 of the slider 30 protrudes into the second slide rail 12. The guide post of the rotating member 20 cooperates with the uppermost end of the guide groove 34 of the slider 30. This is equivalent to the slider 30 pressing one end of the rotating member to a lower position, so the other end of the rotating member 20 is in a higher position. At this time, the first limiting surface 23 of the other end of the rotating member 20 abuts against the upper side wall of the first slide rail 11, and the rotating member 20 is in the first state.
[0056] When the shelf 100 is adjusted from a low position to a high position, pulling the shelf 100 causes the support part 201 to slide along the first slide rail 11 from the first end 111 to the second end 112. When the support part 201 abuts against the rotating part 20, under the user's pulling force, the support part 201 drives the rotating part 20 to rotate until the support part 201 disengages from the rotating part 20 and enters the second end 112. During the rotation of the rotating part 20, the guide post of the rotating part 20 will drive the sliding part 30 to move upward through the compression elastic element 40. After the support part 201 disengages from the rotating part 20, the sliding part 30 returns to the first position under the action of the elastic element 40. Since the second end 112 and the third end 121 overlap, when the support part 201 enters the second end 112 of the first slide rail 11, it is equivalent to the support part 201 entering the third end 121 of the second slide rail 12. Then, when the user pushes the shelf 100 back, since the rotating part 20 is still in the first state, when the user pushes the shelf 100, the rotating part 20 will prevent the support part 201 from entering the first slide rail 11. Therefore, when the user pushes the shelf 100, the support part 201 slides from the third end 121 into the second slide rail 12 towards the fourth end 122. At this time, the sliding part 30 is in the first position, and the first protruding end 33 protrudes into the second slide rail 12. The support part 201 and the second guide surface 331 of the first protruding end 33 cooperate to squeeze the sliding part 30 to move upward to avoid the second slide rail 12, so that the support part 201 enters the fourth end 122, and the shelf 100 is adjusted to the high position. Figure 3 As shown.
[0057] When the sliding member 30 moves upward, when the overlapping surface 311b of the second protruding end 311 is above the supporting surface 13, the snap-fit structure of the second protruding end 311 cooperates with the shelf body 10, and the sliding member 30 will remain in the second position. At this time, the weight of the first rotating arm 21 end of the rotating member 20 can be greater than the weight of the second rotating arm 22 end, so that the rotating member 20 can be held in the second state under the action of gravity. Of course, in some embodiments, the rotating member 20 can also be held in the second state by a tension spring. When the rotating member 20 is in the second state, the second limiting surface 24 of the rotating member 20 abuts against the lower side wall of the limiting groove 123.
[0058] When the shelf 100 is adjusted from the high position to the low position, the shelf 100 is pulled so that the support part 201 slides along the second slide rail 12 from the fourth end 122 to the third end 121. When the support part 201 abuts against the rotating part 20, under the action of the user's pulling force, the support part 201 drives the rotating part 20 to rotate until the support part 201 and the rotating part 20 disengage and enter the third end 121. After the support part 201 and the rotating part 20 disengage, the rotating part 20 returns to the second position under the action of gravity. Because the third end 121 overlaps with the second end 112, when the support part 201 enters the third end 121 of the second slide rail 12, it is equivalent to the support part 201 entering the third end 121 of the first slide rail 11. Then, when the user pushes the shelf 100 back, since the rotating part 20 is still in the second state, when the user pushes the shelf 100, the rotating part 20 will prevent the support part 201 from entering the second slide rail 12. Therefore, when the user pushes the shelf 100, the support part 201 slides from the second end 112 of the first slide rail 11 to the first end 111. At this time, the sliding part 30 is located at... In the second position, the second protruding end 311 protrudes into the first slide rail 11, and the first guide surface 311a of the snap-fit structure protrudes into the first slide rail 11 and faces the second end 112 of the first slide rail 11. When the support part 201 slides from the second end 112 to the first end 111, it will press the second protruding end 311 towards the first end 111 by cooperating with the first guide surface 311a, thereby causing the overlapping surface 311b of the snap-fit structure to disengage from the support surface 13. Then, the sliding member 30 returns to the first position under the action of the elastic member 40, and the rotating member 20 returns to the first state. After the support part 201 disengages from the second protruding end 311, it enters the first end 111, and the shelf 100 is adjusted to the low position.
[0059] like Figure 1 As shown, in another embodiment of this application, a refrigerator 1000 is also provided, which includes a cabinet 200 and any of the shelves 100 as described above. The cabinet 200 is used to form a storage cavity. A support portion 201 is provided on the side wall of the storage cavity. The shelf 100 is disposed in the storage cavity of the refrigerator 1000, and the support portion 201 is embedded in the first slide rail 11 or the second slide rail 12 of the shelf 100.
[0060] The refrigerator 1000 provided in this application adopts all the technical solutions of all the above-mentioned embodiments of the shelf 100, and therefore has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here.
[0061] This application provides a shelf and a refrigerator. The shelf 100 includes a shelf body 10, a rotating member 20, and a sliding member 30. The shelf body 10 is provided with a first slide rail 11 and a second slide rail 12. The first slide rail 11 and the second slide rail 12 are used to cooperate with a support part 201. The first slide rail 11 has a first end 111 and a second end 112. The second slide rail 12 has a third end 121 and a fourth end 122. The second end 112 and the third end 121 overlap, and the first end 111 and the fourth end 122 are spaced apart along the height adjustment direction of the shelf 100. The first end 111 is used to position the shelf 100 at a first height, and the fourth end 122 is used to position the shelf 100 at a second height. The rotating member 20 is rotatably disposed on the shelf body 10. The sliding member 30 is slidably disposed on the shelf body 10. The sliding member 30 is used to control the rotating member 20 to switch between a first state and a second state. In the first state, the rotating member 20 prevents the support portion 201 from entering the first slide rail 11 from the second end 112. In the second state, the rotating member 20 prevents the support portion 201 from entering the second slide rail 12 from the third end 121. The sliding member 30 has a first protruding end 33 and a second protruding end 311. The first protruding end 33 is used to cooperate with the support portion 201 in the second slide rail 12 to move the sliding member 30. The second protruding end 311 forms a snap-fit structure. The snap-fit structure is used to cooperate with the shelf body 10. The snap-fit structure includes a first guide surface 311a. The first guide surface 311a is used to cooperate with the support portion 201 in the first slide rail 11 to disengage the snap-fit structure from the shelf body 10. The shelf 100 provided in this application can be adjusted in height simply by pushing and pulling the shelf 100 during the entire adjustment process. Compared with the prior art, which requires pulling the shelf 100 out of the original height insertion groove and then inserting the shelf 100 into the insertion groove of another height, the adjustment operation of the shelf 100 is effectively simplified.
