[0044] The realization of the purpose, functional features and advantages of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0045] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0046] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0047] In addition, if there are descriptions such as "first" and "second" in the embodiments of the present utility model, the descriptions of "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution where A and B are satisfied simultaneously. In addition, the technical solutions between the embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0048] In the prior art, the shelf is installed on the door liner of the refrigerator door through an installation structure, and the opposite sides of the shelf are movably clamped on the inner side wall of the refrigerator door to achieve lifting adjustment on the refrigerator door. However, in the current installation structure of the shelf, it usually includes a user-controlled handle and a locking member clamped on the refrigerator door. The handle and the locking member are driven by an elastic member, and the locking member is then controlled to reset by another elastic member. Thus, there are many transmission structures between the handle and the locking member, and the sensitivity is low. When the user controls the movement of the handle, the movement amplitude of the locking member is low or even there is a movement delay, resulting in that when the user adjusts the position of the shelf, he needs to deliberately pay attention to the clamping relationship between the locking member and the door liner of the refrigerator to avoid problems such as insufficient unlocking and increased movement difficulty or insufficient locking and unstable clamping, thereby increasing the operation burden of the user.

[0049] The present utility model provides a refrigerator.

[0050] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the refrigerator includes:

[0051] A clamping member 100, which is arranged on the installation wall of the refrigerator;

[0052] A shelf 300, with the side of the shelf 300 opposite to the clamping member 100; and

[0053] A plug member 400 and an adjusting member 500, the plug member 400 is movably arranged on the shelf 300 along a first direction, and the adjusting member 500 is movably arranged on the shelf 300 along a second direction to have a locking state and an unlocking state. The first direction and the second direction intersect. One of the plug member 400 and the adjusting member 500 is provided with a driving wall 410, and the one provided with the driving wall 410 can push the other to move through the driving wall 410;

[0054] Wherein, in the locking state, the plug member 400 extends out of the shelf 300 and is clamped on the clamping member 100. In the unlocking state, the plug member 400 retracts into the shelf 300, and the shelf 300 can move along the extending direction of the clamping member 100.

[0055] The technical solution of the present utility model is to provide a clamping member 100 on the installation wall of the refrigerator, and a plug member 400 and an adjusting member 500 on the shelf 300. The user controls the adjusting member 500 and the plug member 400 to switch between the locked state and the unlocked state, so as to change the connection state between the shelf 300 and the clamping member 100, and the shelf 300 can be adjusted to different positions relative to the clamping member 100 to meet the space requirements for placing items. Among them, when the user controls the adjusting member 500 to move, power is transmitted between the adjusting member 500 and the plug member 400 through a driving wall 410, so that the adjusting member 500 moving along the second direction drives the plug member 400 to extend or retract into the shelf 300 along the first direction, thereby simplifying the commutation transmission structure between the plug member 400 and the adjusting member 500, making the power transmission between the plug member 400 and the adjusting member 500 more sensitive. When the user controls the shelf 300 to switch between the unlocked state and the locked state, the connection relationship between the shelf 300 and the clamping member 100 meets the user's operation expectation, thus providing good operation feedback to the user and improving the operation convenience of the user for adjusting the position of the shelf 300.

[0056] It should be noted that the driving wall 410 can be arranged on the adjusting member 500 or the plug member 400. The driving wall 410 has an extension amount in the first direction and an extension amount in the second direction. When the driving wall 410 is arranged on the adjusting member 500, there is a part on the plug member 400 that slidably abuts against the driving wall 410. During the process of the adjusting member 500 moving in the second direction, the driving wall 410 will occupy the space of the plug member 400 in the first direction, thereby pushing the plug member 400 to move in the first direction. Among them, driving walls 410 can be arranged on both sides of the adjusting member 500 along the first direction. The plug member 400 respectively has parts that relatively abut against the two driving walls 410 along the first direction, but the plug member 400 will not hinder the movement of the adjusting member 500 in the second direction, so that the adjusting member 500 can drive the plug member 400 to move back and forth in the first direction. Or, the adjusting member 500 can also be provided with a driving wall 410 on one side along the first direction. The plug member 400 has a part that relatively slidably abuts against the driving wall 410. At the same time, a reset member is also arranged on the plug member 400. The reset member drives the plug member 400 to move in the direction away from the direction in which the driving wall 410 pushes the plug member 400, so as to realize the unilateral movement of the adjusting member 500 driving the plug member 400 in the first direction. The reset member drives the plug member 400 to move on the other side in the first direction and drives the adjusting member 500 to reset in the second direction. For the driving wall 410 arranged on the plug member 400, the cooperation relationship between the plug member 400 and the adjusting member 500 can be adaptively adjusted with reference to the above description of the driving wall 410 arranged on the adjusting member 500. Without loss of generality, the plug member 400 needs to be maintained in the locked state more often, that is, the plug member 400 needs to be in a steady state when it extends out of the shelf 300 and is clamped to the clamping member 100. Here, when the adjusting member 500 or the plug member 400 is in the locked state, it can be clamped to the shelf 300 to be in a stable state. Or, the reset member is used to make the adjusting member 500 or the plug member 400 have a tendency to maintain in the locked state. The operation required by the user is: controlling the adjusting member 500 to switch from the locked state to the unlocked state or from the unlocked state to the locked state.

[0057] It can be understood that for the driving wall 410 having extension components in both the first direction and the second direction, the driving wall 410 can be configured as a straight inclined wall or an arc-shaped wall. Referring to Figure 2 , in the embodiments of the present invention, the first direction and the second direction are used to explain in such as Figure 2The relative positional relationship, movement conditions, etc. of the plug member 400 and the adjusting member 500 in the posture. If the specific posture of the refrigerator changes, the directional indication also changes accordingly. In addition, the installation wall of the refrigerator can be a single side wall body, that is, the plug member 400 and the adjusting member 500 are set in a single group. Or, the installation wall is configured as two opposite wall bodies, and the opposite sides of the shelf 300 are respectively opposite to the engaging members 100 on the two installation walls. Correspondingly, the plug members 400 on the shelf 300 are also set in two groups, and the adjusting member 500 can also be set in two groups to realize the individual control of the two plug members 400. Or, the adjusting member 500 can also be set as one component to realize the unified control of the two plug members 400. At this time, the user can adjust the position of the shelf 300 with a single hand operation, which can free the other hand of the user, giving the user more operating space and improving the operation convenience of the user to adjust the position of the shelf 300. Of course, for the relatively simplified transmission structure of this solution, compared with the relatively complex transmission structure in the prior art, this solution reduces the occupied space, can improve the space utilization rate of the refrigerator, and at the same time, reduces the possibility of failures occurring during the transmission of the adjusting member 500 and the plug member 400, thereby reducing the maintenance cost.

[0058] In one embodiment, please refer to Figure 2 and Figure 3 , the driving wall 410 extends obliquely relative to both the first direction and the second direction. It can be understood that the driving wall 410 is configured as a straight inclined wall and has an extension component along the first direction and an extension component along the second direction, and at the same time, it is not parallel to the first direction and the second direction. In this way, the driving wall 410 enables the transmission force line between the adjusting member 500 and the plug member 400 to be transmitted along a straight line or a path close to a straight line, reducing the dispersion and deviation of the transmission force, and helping to ensure that the interaction between the plug member 400 and the adjusting member 500 is more direct and efficient. At the same time, the user can feel a stable and uniform feedback during the operation process, making it easier to control the height adjustment of the shelf 300. Of course, in other embodiments, the driving wall 410 can also be set as an arc wall, so that the transmission force between the adjusting member 500 and the plug member 400 can gradually transition during the transmission process, reducing the sudden change and impact of the force, helping to reduce mechanical wear and noise, and improving the durability and comfort of the system.

[0059] In one embodiment, please refer to Figure 2 and Figure 3, the driving wall 410 is arranged on the latch member 400, and the adjusting member 500 is slidably abutted against the driving wall 410. It can be understood that the adjusting member 500 controls the extension or retraction of the latch member 400 by sliding against the driving wall 410, which reduces the intermediate links, improves the transmission efficiency, and makes the height adjustment of the shelf 300 more rapid and accurate. As for the assembly method, it is only necessary to install the latch member 400 and the driving wall 410 as a whole on the shelf 300, and then connect the adjusting member 500 with the driving wall 410, which simplifies the assembly process, reduces the assembly difficulty, and improves the production efficiency. In addition, the adjusting member 500 acts on the driving wall 410 arranged on the latch member 400, and the driving wall 410 obtains the force from the adjusting member 500 and directly feeds back to the activity of the latch member 400, which reduces the deviation of the latch member 400 during the reversing transmission process and improves the accuracy of the activity of the latch member 400 along the first direction. Of course, in other embodiments, the driving wall 410 may also be disposed on the adjusting member 500 , and the latch member 400 relatively avoids the adjusting member 500 along the second direction and has a portion that can slidably abut against the driving wall 410 to obtain transmission force from the driving wall 410 .

[0060] Further, in this embodiment, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7, the adjusting member 500 includes a pulling portion 510 and a transmission portion 520 connected to each other. The driving wall 410 is disposed on the side of the plug member 400 away from the pulling portion 510. The transmission portion 520 straddles the plug member 400 and abuts against the driving wall 410. It can be understood that during the process of the transmission portion 520 pushing against the driving wall 410, the adjusting member 500 moves away from the plug member 400. Thus, when the user pulls the pulling portion 510, it prompts the transmission portion 520 to push against the driving wall 410, and further drives the plug member 400 to move in the first direction. Generally speaking, when the transmission portion 520 pushes against the driving portion, the plug member 400 retracts onto the shelf 300, that is, switches from the locked state to the unlocked state, and then adjusts the position of the shelf 300 to adapt to the user's hand force application habit. Moreover, after the user pulls the pulling portion 510, it also has the function of supporting and holding the shelf 300 downward, facilitating the adjustment of the position of the shelf 300 along the clamping strip. For the plug member 400 and the adjusting member 500 to return from the unlocked state to the locked state, a driving wall 410 can be added to the plug member 400. When the adjusting member 500 moves in the direction close to the plug member 400, the transmission portion 520 can slide and push against the driving wall 410, so that the plug member 400 extends out of the shelf 300 again and is clamped in the clamping member 100. After the plug member 400 is stably clamped in the clamping member 100, at least one of the adjusting member 500 and the plug member 400 is clamped in the shelf 300 to be in a stable state, ensuring the stability of the shelf 300 on the installation wall. Of course, in other embodiments, the driving wall 410 can also be disposed on the side of the plug member 400 facing the adjusting member 500, and act on the driving wall 410 in the way of pushing the adjusting member 500, so as to control the movement of the plug member 400 in the first direction.

[0061] Specifically, in this embodiment, please refer to Figure 3, the transmission part 520 includes a transmission body and an abutting convex part 521. The transmission body is connected to the pulling part 510 and straddles the pin part 400. The abutting convex part 521 protrudes from the transmission body toward the pin part 400 and abuts against the driving wall 410 relatively. The corner part of the abutting convex part 521 abutting against the driving wall 410 is configured as a rounded corner. It can be understood that the rounded corner makes the contact surface between the abutting convex part 521 and the driving wall 410 smoother, thereby reducing the friction coefficient between the two, helping to reduce the heat and wear generated by friction during the adjustment process, and extending the service life of the components. At the same time, the rounded corner can disperse the pressure of the abutting convex part 521 on the driving wall 410, making the pressure distribution on the contact surface more uniform, and helping to prevent material deformation or damage caused by excessive local pressure. Similarly, the rounded corner reduces the sharp corners or uneven surfaces that the abutting convex part 521 may encounter during the sliding process, thereby reducing the risk of jamming, making the adjusting part 500 slide more smoothly during the sliding process, and improving the user experience. In addition, for the reset part provided on the pin part 400 to make the pin part 400 and the adjusting part 500 automatically reset from the unlocked state to the locked state, the corner part of the abutting convex part 521 abutting against the driving wall 410 is configured as a rounded corner. During the reset process of the pin part 400 and the adjusting part 500, the driving wall 410 pushes against the abutting convex part 521, and can be as smooth as the abutting convex part 521 pushing against the driving wall 410, so as to facilitate the reset of the pin part 400 and the adjusting part 500 from the unlocked state to the locked state.

[0062] Further, in this embodiment, please refer to Figure 2 , Figure 4 and Figure 8 , the shelf 300 has an opening, and the pulling part 510 has a part exposed in the opening. It can be understood that when the user controls the pulling part 510, the user can act on the pulling part 510 at the opening. In this way, the user only needs to simply stretch out a finger or a palm to easily grasp the pulling part 510 and perform the adjustment operation, and it is not easy to have misoperation or misjudgment during the operation, reducing the user's learning cost and usage difficulty. At the same time, the part of the pulling part 510 exposed in the opening enables the user to directly see and touch the pulling part 510 without moving other items, thereby greatly improving the convenience of the user's operation. Without loss of generality, the design of the pulling part 510 usually takes into account the ergonomic principle to ensure that the user can hold and adjust comfortably. The part exposed in the opening enables the user to approach the pulling part 510 more naturally, thereby obtaining a better holding experience.

[0063] In an embodiment, please refer to Figure 4, a first guiding groove 322 is provided in the shelf 300. The first guiding groove 322 extends along the second direction, and the adjusting member 500 is slidably disposed in the first guiding groove 322. It can be understood that the first guiding groove 322 provides a clear movement trajectory for the adjusting member 500, which helps to ensure that the adjusting member 500 moves in a straight line during movement, avoiding deviation or distortion, thereby improving the accuracy and reliability of adjustment. At the same time, the guiding groove can reduce the direct contact between the adjusting member 500 and other parts of the shelf 300 during movement, thereby reducing friction and wear. This not only helps to extend the service life of the adjusting member 500 and the shelf 300, but also reduces the noise and vibration generated by friction. Of course, in other embodiments, it may also be that guiding ridges are provided on the shelf 300 and guide rails are provided on the adjusting member 500. The guiding ridges extend along the second direction and are slidably inserted into the guide rails.

[0064] Further, in this embodiment, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 , the adjusting member 500 includes a pulling part 510 and a balancing part 530 which are connected. The balancing part 530 is located on the side of the pulling part 510 away from the plug member 400. The balancing part 530 extends along the second direction and slidably abuts against the groove wall of the first guiding groove 322 in the first direction. Referring to the force transmission between the transmission part 520 of the adjusting member 500 and the plug member 400 above, when the user operates the adjusting member 500 through the pulling part 510, a force in the first direction will be generated between the adjusting member 500 and the plug member 400. If only the transmission part 520 bears this force, it may cause local stress concentration, and there is a certain distance between the connection part of the pulling part 510 and the transmission part 520 and the plug member 400, so that the stress borne by the pulling part 510 is relatively large. Thus, with the connection part of the pulling part 510 and the transmission part 520 as the fulcrum, on the side away from the plug member 400, the adjusting member 500 is further provided with a balancing part 530, which can effectively disperse this part of the stress, so that the force can be more evenly distributed on the adjusting member 500, thereby improving the stability and service life of the adjusting member 500. In addition, the balancing part 530 extends along the second direction and slidably abuts against the groove wall of the first guiding groove 322 in the first direction, which not only provides support for balancing the adjusting member 500, but also enhances its stability during operation. Specifically, the supporting part is connected to the transmission part 520, and the pulling part 510 is connected to the connection part of the supporting part and the transmission part 520, forming a lever force with the pulling part 510 as the fulcrum, thereby improving the stability of the adjusting member 500.

[0065] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7, the refrigerator further includes an elastic member 600. The elastic member 600 is clamped between the shelf 300 and the latch member 400 and has a tendency of elastic deformation in the first direction. It can be understood that when the elastic member 600 elastically deforms in the first direction, it has a tendency to push the latch member 400 to move in the first direction. After the adjusting member 500 acts on the driving wall 410 to control the movement of the latch member 400, the elastic member 600 increases its elastic potential energy. Thus, after the acting force of the adjusting member 500 on the latch member 400 is removed, the elastic member 600 will automatically return to its original state by using its elastic force, thereby driving the latch member 400 and the adjusting member 500 to reset to the locked state, so that the user does not need to manually reset the latch member 400 after completing the adjustment of the shelf 300, thus improving the convenience and comfort of use. Specifically, the elastic member 600 can be located at the front side where the latch member 400 extends outward from the shelf 300 and is configured as a tension spring. Correspondingly, when the adjusting member 500 acts on the driving wall 410, it controls the latch member 400 to switch from the locked state to the unlocked state. At this time, the elastic member 600 has a tendency of elastic contraction. Once the adjusting member 500 removes the acting force on the driving wall 410, the elastic member 600 directly drives the latch member 400 to snap outward into the engaging member 100. At the same time, the adjusting member 500 is urged to reset in the second direction through the driving wall 410, so that the latch member 400 and the adjusting member 500 return to the locked state and keep the latch member 400 stably clamped in the engaging member 100, ensuring the installation stability of the shelf 300 in the refrigerator. Similarly, in another embodiment, the elastic member 600 can also be located at the front side where the latch member 400 retracts into the shelf 300. At this time, the elastic member 600 is configured as a compression spring. Referring to the above action process, it uses elastic thrust to urge the latch member 400 to be stably clamped in the engaging member 100 to achieve automatic reset. Of course, in other embodiments, two opposite driving walls 410 can also be provided on the latch member 400. The adjusting member 500 has portions that respectively abut against the two driving walls 410 in the first direction, and when these portions move in the second direction, they move synchronously in the first direction to achieve the adjusting member 500 to control the back-and-forth movement of the latch member 400 in the first direction.

[0066] Further, in this embodiment, please refer to Figures 2 to 4 , Figure 6 and Figure 7, the shelf 300 is provided with a second guiding groove 326323 extending along the first direction. An avoidance opening 324 communicating with the second guiding groove 326323 is formed in the side portion of the shelf 300. The latch member 400 is slidably disposed in the second guiding groove 326323 and can extend out of the avoidance opening 324. The elastic member 600 abuts against one end of the latch member 400 away from the avoidance opening 324 and has a tendency of elastic elongation. It can be understood that when the latch member 400 is in the unlocked state, during the process of returning to the locked state, the elastic member 600 will continuously apply a forward thrust to the latch member 400, pushing the latch member 400 to slide along the second guiding groove 326323 until it extends out of the avoidance opening 324 and inserts into the engaging member 100 that cooperates with it, thereby ensuring that the shelf 300 can be stably maintained in the locked state without being actively unlocked. At the same time, due to the continuous thrust provided by the elastic member 600, the latch member 400 will be subjected to an additional pressure when in the locked position, thereby enhancing the contact tightness and stability with the locking hole, helping to prevent the latch member 400 from loosening or falling off due to external factors such as vibration and temperature changes, and further improving the safety and stability of the shelf 300. Of course, when unlocking is required, the user only needs to apply a force in the opposite direction to the latch member 400 through the adjusting member 500 to overcome the thrust of the elastic member 600 and pull the latch member 400 back into the avoidance opening 324, realizing the unlocking of the shelf 300, simplifying the unlocking process, and improving the operation convenience. In addition, the second guiding groove 326323 also limits the movement of the latch member 400 only in the first direction, thereby ensuring the stability of the latch member 400 when switching between the locked state and the unlocked state.

[0067] In one embodiment, please refer to Figure 6 and Figure 7, the elastic member 600 and the latch member 400 are on the same straight line, and the portion of the adjusting member 500 abutting against the driving wall 410 is arranged close to the elastic member 600. Since the elastic member 600 and the latch member 400 are on the same straight line, the thrust generated by the elastic member 600 can be directly and efficiently transmitted to the latch member 400, thereby reducing the dispersion and loss of force, enabling the latch member 400 to slide more stably along the second guiding groove 326323 and smoothly extend out of the avoidance opening 324 to be stably clamped to the clamping member 100. At the same time, the layout of the elastic member 600, the latch member 400 and the avoidance opening 324 on the same straight line makes the thrust direction of the elastic member 600 on the latch member 400 clear and stable. This stability helps to prevent the latch member 400 from shifting or shaking during the sliding process, thus ensuring that the latch member 400 can accurately insert into the clamping member 100 to achieve the stable locking of the shelf 300. In addition, the portion of the adjusting member 500 abutting against the driving wall 410 is arranged close to the elastic member 600, enabling the user to more effectively transmit force to the elastic member 600 when operating the adjusting member 500, so as to ensure the effect of increasing the elastic potential energy of the elastic member 600, thereby improving the stability and efficiency of the automatic reset of the latch member 400 and the adjusting member 500. Of course, in other embodiments, the straight line where the elastic member 600 is located and the straight line where the latch member 400 faces the avoidance opening 324 can also be arranged in parallel.

[0068] Further, in this embodiment, please refer to Figure 6 and Figure 7 , the elastic member 600 is configured as a compression spring, and the latch member 400 and the shelf 300 are provided with limiting convex portions 420, and the limiting convex portions 420 are inserted into the ends of the compression spring. It can be understood that the ends of the compression spring are firmly inserted by the limiting convex portions 420, preventing the compression spring from shifting or falling off when subjected to an external force. In this way, the limiting convex portions 420 can ensure that the position of the compression spring remains relatively stable when it is compressed or released, thereby ensuring the stability and reliability of the switching between the unlocking state and the locking state of the latch member 400 and the adjusting member 500. At the same time, when the refrigerator is running or the user operates the shelf 300, certain vibrations may occur. The limiting convex portions 420 reduce the shaking of the compression spring caused by the vibration by fixing the position of the compression spring, further improving the stability of the switching between the unlocking state and the locking state of the latch member 400 and the adjusting member 500. Without loss of generality, the two limiting convex portions 420 face each other and have a certain distance. In this way, the limiting convex portions 420 limit the deformation range of the compression spring, so that the compression spring will not be overly deformed when compressed, thus avoiding performance degradation or damage caused by excessive deformation. Of course, in other embodiments, limiting blind holes are provided on the groove side wall of the second guiding groove 326323 and the side portion of the latch member 400, and the two ends of the compression spring are inserted into the limiting blind holes.

[0069] In one embodiment, please refer to Figure 2 、Figure 6 and Figure 7 , the shelf 300 includes a base and a shelf body 310. The base includes a shell part 321 and a cover part 329 that are joined together. The plug-in member 400 and the adjusting member 500 are movably disposed in the shell part 321, and the cover part 329 abuts against the shelf body 310. It can be understood that the base is divided into two half-shells, namely the shell part 321 and the cover part 329. Technicians only need to install components such as the plug-in member 400 and the adjusting member 500 into the shell part 321, and then join the cover part 329 with the shell part 321 to assemble the base, without complex positioning and fixing steps, making the assembly process more intuitive and simple. At the same time, first the base is assembled, and then the base and the shelf body 310 are connected to support the shelf body 310, so that the installation of the shelf 300 is in the form of module joining, which can reduce the installation time, improve the production efficiency and user satisfaction. Of course, in other embodiments, a part for installing the plug-in member 400 and the adjusting member 500 can also be directly provided at the bottom plate of the shelf 300, that is, the plug-in member 400 and the adjusting member 500 are directly installed on the shelf 300.

[0070] Further, in this embodiment, please refer to Figure 2 and Figure 4 , at least one of the shell part 321 and the cover part 329 is provided with a first rib 325. The first rib 325 extends along the moving direction of the adjusting member 500 and slidably abuts against the adjusting member 500. It should be noted that the adjusting member 500 contacts the first rib 325 during the sliding process. The shape and distribution of the first rib 325 can effectively disperse the pressure on the contact surface, thereby helping to reduce the friction force per unit area, making the movement of the adjusting member 500 smoother and reducing the operation difficulty of the user. In addition, the first rib 325 extends along the moving direction of the adjusting member 500, providing a clear sliding path for the adjusting member 500, which helps to ensure the linearity and stability of the adjusting member 500 during the movement process, and reduces the additional friction force caused by deviation or shaking. Without loss of generality, a lubricant (such as lubricating oil or grease) may be applied to the contact surface between the first rib 325 and the adjusting member 500. Here, the presence of the first rib 325 can further promote the uniform distribution and retention of the lubricant, thereby enhancing the lubrication effect and further reducing the friction force.

[0071] In one embodiment, please refer to Figure 4 and Figure 7, the housing part 321 and the cover part 329 are connected by a snap structure. Without loss of generality, the snap structure includes a bayonet 328 and a snap 327. A plurality of snaps 327 are provided on the cover part 329. Correspondingly, a plurality of bayonets 328 are provided on the housing part 321. The plurality of snaps 327 and the plurality of bayonets 328 are snap-connected one by one. In this way, technicians can align the two and apply an appropriate force to achieve positioning and alignment through the snap structure while also achieving a tight connection without additional fasteners or complex operation steps, thereby improving the assembly efficiency of the chassis 320. Similarly, the snap structure is not only convenient for assembly but also for disassembly. When it is necessary to repair or replace the shelf 300 components, the user can easily disassemble the snap structure, take out the components that need to be repaired or replaced, and then reassemble them, thereby reducing the repair difficulty and cost and improving the usability and economy of the shelf 300. In addition, a plurality of positioning frames are provided on the housing part 321. The positioning frames can enclose a first guide groove 322 and a second guide groove 326323 to provide positioning for the installation of the plug-in member 400 and the adjusting member 500 and form a limit guide for the movement of the plug-in member 400 and the adjusting member 500. Among them, the snap 327 is provided on the above-mentioned positioning frame, which not only reduces the space occupied by the snap structure but also ensures the limiting effect of the positioning frame on the plug-in assembly and the adjusting member 500. Of course, in other embodiments, the housing part 321 and the cover part 329 can also be connected by means of screw attachment or riveting.

[0072] In one embodiment, please refer to Figure 5 , Figure 7 and Figure 8, a mounting groove 313 is recessed at the bottom of the shelf body 310, the base is adaptively mounted in the mounting groove 313, a relief opening 314 is formed in the groove wall of the mounting groove 313 facing the clamping member 100, and in the locked state, the bolt member 400 is clamped to the clamping member 100 through the relief opening 314. It can be understood that the design of the mounting groove 313 enables the base to be accurately and adaptively mounted at the bottom of the shelf body 310, providing a stable support foundation for the plate body of the shelf 300, ensuring that the shelf body 310 does not shake or tilt when carrying items, thereby ensuring the safety and stability of the items inside the refrigerator. At the same time, the formation of the relief opening 314 provides a space for the bolt member 400 to pass through, enabling the bolt member 400 to be clamped to the clamping member 100 through the relief opening 314 when needed, not only increasing the connection stability between the shelf body 310 and the base, but also ensuring the convenience of switching between the locked state and the unlocked state of the bolt member 400, thereby ensuring that the height or position of the shelf 300 can be flexibly adjusted according to needs to meet the storage requirements of items of different sizes and shapes. Without loss of generality, the chassis 320 is mounted in the mounting groove 313 by a clamping method. After the chassis 320 and the shelf body 310 are integrally formed, the shelf 300 can be assembled by a clamping method, making the installation and disassembly between the shelf body 310 and the base simple and fast. Users can easily complete the installation and disassembly of the shelf 300 without using complex tools or performing cumbersome operations, improving the convenience of use. In addition, a limiting protrusion (not shown in the figure) is provided at the periphery of the relief opening 314, and a third guiding groove (not shown in the figure) is correspondingly provided on the bolt member 400. The limiting protrusion is slidably clamped in the third guiding groove. During the process of the bolt member 400 switching between the locked state and the unlocked state, the guiding cooperation between the limiting protrusion and the third guiding groove ensures the stability and smoothness of the movement of the bolt member 400 in the first direction. Of course, in other embodiments, the base may also be provided with a receiving cavity, and the shelf body 310 is limited and mounted in the receiving cavity to assemble the shelf 300.

[0073] In one embodiment, please follow Figure 1 and Figure 5, on one side of the shelf body 310 facing the clamping member 100, there is a sliding groove 311. The sliding groove 311 extends along the extending direction of the clamping member 100. The clamping member 100 is movably inserted into the sliding groove 311. In the locked state, the sliding groove 311 is clamped with the clamping member 100. It can be understood that the setting of the sliding groove 311 provides a clear track for the lifting of the shelf body 310 along the clamping member 100. Under the limiting action of the sliding groove 311, the shelf body 310 can move freely along the extending direction of the clamping member 100. Without the need for the user to use complex tools or perform cumbersome operation steps, the position adjustment of the shelf 300 can be realized, making the lifting operation of the shelf 300 intuitive and easy to control. Moreover, the relative movement of the sliding groove 311 and the clamping member 100 restricts and guides the shelf body 310, avoiding the shaking or deviation of the shelf 300 during lifting, thus ensuring the safety and stability of the items. Of course, in other embodiments, straight grooves can also be provided on the clamping member 100, and the shelf body 310 or the chassis 320 has parts slidably connected to the straight grooves to provide guiding and limiting effects on the shelf body 310 when adjusting the position of the shelf 300, improving the adjustment convenience for the user.

[0074] Further, in this embodiment, please refer to Figure 1 and Figure 5 , on the groove wall of the sliding groove 311, there are second convex ribs 312 protruding. The second convex ribs 312 are in contact with the side wall of the clamping member 100. Referring to the above description of the first convex rib 325, the design of the second convex ribs 312 enables the side wall of the clamping member 100 not to directly contact the bottom or the entire groove wall of the sliding groove 311 when the shelf body 310 slides relative to the clamping member 100, but to be in contact with the protruding second convex ribs 312, thereby effectively dispersing the pressure on the contact surface and reducing the frictional resistance during the process of adjusting the position of the shelf 300, thus improving the use convenience for the user.

[0075] In one embodiment, please refer to Figure 1 and Figure 9 , the refrigerator includes a refrigerator door 200, and the installation wall is configured as the inner wall of the refrigerator door 200. Without loss of generality, the usual installation position of the shelf 300 is the refrigerator door 200. Correspondingly, the installation wall is also configured as the inner wall of the refrigerator door 200. In this way, the space inside the refrigerator can be fully utilized, and the storage capacity of the refrigerator can be improved. Of course, in another embodiment, the installation wall can also be configured as the cavity wall in the refrigerating compartment or the freezing compartment inside the refrigerator, thus providing more diversified and convenient storage options for the user.

[0076] In one embodiment, please refer to Figure 1 , Figure 9 and Figure 10, the clamping member 100 is provided with a plurality of clamping grooves 110 facing the shelf 300. The plurality of clamping grooves 110 are distributed along the extending direction of the clamping member 100. The upper groove wall of the clamping groove 110 extends obliquely towards the adjacent clamping groove 110, and the lower groove wall of the clamping groove 110 extends horizontally. In the locked state, the plug member 400 is selectively clamped in the clamping groove 110. It can be understood that the clamping member 100 extends in the vertical direction, and the plurality of clamping grooves 110 distributed along its extending direction provide a plurality of different adjustment positions for the shelf 300. Users can, according to actual needs, insert the plug member 400 into different clamping grooves 110, so as to achieve precise adjustment of the height of the shelf 300. At the same time, the clamping grooves 110 make the adjustment operation of the shelf 300 simple and fast. The user only needs to pull out the plug member 400 from the current clamping groove 110 and then insert it into the adjacent clamping groove 110 to complete the height adjustment of the shelf 300, thereby simplifying the adjustment process. In addition, when the plug member 400 is clamped into the clamping groove 110, its top will be smoothly guided by the inclined upper groove wall and enter the inside of the clamping groove 110; once the plug member 400 reaches the bottom of the clamping groove 110, the horizontal extension of the lower groove wall will provide a stable supporting force to prevent the plug member 400 from accidentally coming out, thereby enhancing the locking effect of the plug member 400 in the clamping groove 110; similarly, the upper groove wall of the clamping groove 110 extends obliquely, and when the user adjusts the position of the shelf 300 upwards, the upper groove wall of the clamping groove 110 can also reduce the resistance to the plug member 400, thereby improving the operation convenience of the user to adjust the shelf 300 upwards. Of course, in other embodiments, a plurality of clamping holes can also be provided along the extending direction of the clamping member 100. In the locked state, the plug member 400 is selectively clamped in the clamping holes.

[0077] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
