Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and particularly to a refrigerator height adjustment structure and a refrigerator thereof. Background Art

[0002] With the development of technology, social economy and the improvement of people's living standards, refrigerators have become essential household appliances for every family, used for storing food materials.

[0003] During the installation of a refrigerator, if the ground is uneven, the bottom surface of the refrigerator will be uneven, causing the refrigerator to tilt. The current adjustment method is usually to adjust the feet of the refrigerator or add shims to adjust the refrigerator to be flush with the cabinet. For example, after finding the unevenness, it is necessary to move the refrigerator, then add shims under the position of the support roller unit of the refrigerator to raise it, and then push the refrigerator to the corresponding position, which is troublesome and laborious to operate. Summary of the Invention

[0004] In view of the above technical problems, the present invention provides a refrigerator height adjustment structure.

[0005] A refrigerator height adjustment structure is installed at the bottom of the refrigerator, and includes: a fixed component fixedly connected to the bottom of the refrigerator; a driving component including a screw rod and a mating block, the screw rod passes through the fixed component and the mating block and can rotate around the axis, the mating block is slidably connected to the fixed component and is in threaded cooperation with the screw rod, and can move along the axial direction of the screw rod in response to the rotation of the screw rod; an adjustment component for abutting against the ground, and one end of the adjustment component is connected to the fixed component, the other end is connected to the mating block, and rises or falls in the vertical direction as the mating block moves.

[0006] With such a setting, the fixed component is fixedly connected to the bottom of the refrigerator, and its position remains relatively fixed. The screw rod is in threaded cooperation with the mating block. Therefore, when the screw rod rotates around its axis, it will drive the mating block to slide relative to the fixed component. While the mating block moves, it drives the adjustment component to move, and the adjustment component moves in the vertical direction in response to the movement of the mating block. When the adjustment component descends, that is, the distance between the adjustment component and the bottom of the refrigerator increases. Also, because the adjustment component abuts against the ground and its lowest position will not change, the descent of the adjustment component relative to the bottom of the refrigerator actually means that the refrigerator rises relative to the adjustment component, that is, the function of raising the refrigerator is realized. Similarly, the rise of the adjustment component means the relative position of the refrigerator drops.

[0007] In one embodiment, the adjusting assembly includes a connecting rod unit and a roller unit. One end of the connecting rod unit is connected to the fixing assembly, and the other end is connected to the mating block. The roller unit is connected to the connecting rod unit.

The two fourth connecting holes are coaxially arranged and are both rotatably connected to the support shaft.

[0015] In one embodiment, the two first connecting plates and the second connecting plates are arranged alternately along the axial direction of the roller unit, and one first connecting plate is located between the two second connecting plates.

[0016] In one embodiment, the first connecting plate includes a first connecting portion and second connecting portions located at both ends of the first connecting portion.

The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.

[0034] The present invention provides a refrigerator height adjustment structure 101, which can drive the mating block 22 to move through the drive assembly 20, so that the adjustment assembly 30 is raised or lowered, thereby realizing the height adjustment of the refrigerator 100 and simplifying the steps of adjusting the height of the refrigerator 100.

[0035] Please refer to Figures 1-6, the refrigerator height adjustment structure 101 is installed at the bottom of the refrigerator 100 and is used to adjust the height of the refrigerator 100 without moving the refrigerator 100. It includes a fixed component 10, a driving component 20, and an adjustment component 30. The fixed component 10 is fixedly connected to the bottom of the refrigerator 100; the driving component 20 includes a screw rod 21 and a mating block 22. The screw rod 21 passes through the fixed component 10 and the mating block 22 and can rotate around its axis. The mating block 22 is slidably connected to the fixed component 10, is in threaded cooperation with the screw rod 21, and can move along the axial direction of the screw rod 21 in response to the rotation of the screw rod 21; the adjustment component 30 is used to abut against the ground, and one end of the adjustment component 30 is connected to the fixed component 10, and the other end is connected to the mating block 22, and rises or falls in the vertical direction as the mating block 22 moves. In this way, the fixed component 10 is fixedly connected to the bottom of the refrigerator 100, and its position remains relatively fixed. The screw rod 21 is in threaded cooperation with the mating block 22. Therefore, when the screw rod 21 rotates around its axis, it will drive the mating block 22 to slide relative to the fixed component 10. While the mating block 22 moves, it drives the adjustment component 30 to move, and the adjustment component 30 moves in the vertical direction in response to the movement of the mating block 22. When the adjustment component 30 descends, that is, the distance between the adjustment component 30 and the bottom of the refrigerator 100 increases. Also, because the adjustment component 30 abuts against the ground, its lowest position will not change. Therefore, the descent of the adjustment component 30 relative to the bottom of the refrigerator 100 is actually the rise of the refrigerator 100 relative to the adjustment component 30, that is, the function of raising the refrigerator 100 is realized. Similarly, the rise of the adjustment component 30 is the relative position descent of the refrigerator 100.

[0036] It should be noted that the above-mentioned screw rod 21 refers to a long rod structure with threads provided on its outer peripheral wall. Optionally, the above-mentioned screw rod 21 can be set to have external threads provided from one end to the other end, or can be set to have external threads for threaded connection with the mating block 22 only at the end close to the mating block 22. Preferably, in this embodiment, the external threads on the screw rod 21 extend along the axial direction of the screw rod 21, and the length of its extension is the preset moving distance of the mating block 22 in the embodiment.

[0037] In addition, the above-mentioned upper or lower in the vertical direction refers to the upper and lower in the direction of gravity when the refrigerator 100 is in a normal working state placed on a horizontal ground.

[0038] The adjusting assembly 30 includes a connecting rod unit 31 and a roller unit 32. One end of the connecting rod unit 31 is connected to the fixing assembly 10, and the other end is connected to the mating block 22. The roller unit 32 is connected to the connecting rod unit 31. As the mating block 22 moves, the connecting rod unit 31 can protrude away from the bottom of the refrigerator 100 and drive the roller unit 32 to move away from the bottom of the refrigerator 100. In this way, the adjusting assembly 30 is configured in the form of a connecting rod and a roller 321. The roller 321 facilitates the pushing and pulling movement of the refrigerator 100, while the connecting rod can easily protrude downward in response to the movement of the mating block 22. When the connecting rod unit 31 protrudes downward, it is supported on the roller 321 and supports the entire refrigerator 100.

[0039] Understandably, in other embodiments, the adjusting unit can also be configured as other structures that can be lifted and lowered. For example, a vertically extending threaded rod and a roller 321 are provided. A threaded hole is formed in the base of the roller 321 to be threadedly engaged with the threaded rod to achieve lifting and lowering. The rotation of the threaded rod can be driven by a motor, and the motor is triggered by the mating block 22, etc. In this embodiment, the above-described connecting rod unit 31 is adopted.

[0040] The adjusting assembly 30 further includes a support shaft 33. The support shaft 33 passes through the roller unit 32 and is coaxially arranged with the roller unit 32. The connecting rod unit 31 at least includes a first connecting rod 311 and a second connecting rod 312. One end of the first connecting rod 311 is connected to the fixing assembly 10, and the other end is movably connected to the support shaft 33. One end of the second connecting rod 312 is connected to the mating block 22, and the other end is movably connected to the support shaft 33. In this way, when the mating block 22 moves, one end of the second connecting rod 312 is driven by the mating block 22 and moves toward the first connecting rod 311. Since the length of the second connecting rod 312 remains unchanged, the second connecting rod 312 drives the roller unit 32 to move downward.

[0041] In other embodiments, the adjusting assembly 30 can also add connecting rods to improve the support strength and structural strength of the connecting rod unit 31.

[0042] Optionally, the support shaft 33 is provided with a connecting rod unit 31 at both ends. That is to say, a connecting rod unit 31 is provided on each side of the roller unit 32. The two connecting rod units 31 have the same structure and can support the roller unit 32 on both sides of the roller unit 32 to prevent the roller unit 32 from being inclined due to unilateral force, thereby improving the stability of the refrigerator height adjustment structure 101.

[0043] Furthermore, in this embodiment, the roller unit 32 includes two rollers 321. The two rollers 321 are coaxial and spaced apart, thereby further improving the stability of the roller unit 32 when it is supported on the ground. And in this embodiment, the sides of the two rollers 321 facing away from each other are set as planes, reducing interference with other structures in the vertical direction, thereby improving the height adjustment ability and having a larger adjustment range.

[0044] In another embodiment, the roller unit 32 can also be set as a single roller 321, and the roller 321 has two spaced-apart wheel bodies, and an arc-shaped convex portion is provided on the side of the two wheel bodies facing away from each other to improve its structural strength.

[0045] The fixing component 10 includes a fixing base 11 and a fixing block 12. The fixing base 11 is connected to the bottom of the refrigerator 100, the fixing block 12 is connected to the fixing base 11, and the screw 21 passes through the fixing base 11 and is in threaded cooperation with the fixing base 11; a guiding groove 111 is formed in the fixing base 11, a cooperating convex column 221 protrudes from the cooperating block 22, and a part of the cooperating convex column 221 passes through the guiding groove 111 and abuts against the groove side wall of the guiding groove 111. In this way, the guiding groove 111 on the fixing base 11 can abut against the cooperating convex column 221, limit the movement of the cooperating convex column 221, guide the guiding direction of the cooperating convex column 221, and thus guide the movement direction of the cooperating block 22. And the fixing block 12 is also connected to the link unit 31, playing a role in supporting the link unit 31.

[0046] The fixing component 10 is divided into a fixing base 11 and a fixing block 12. The two can be processed separately and then connected together, reducing the process difficulty and improving the overall structural strength after the two are assembled. The guiding groove 111 formed in the fixing base 11 will not affect the structural strength of the fixing block 12.

[0047] Furthermore, the fixing base 11 includes two spaced-apart side plates 112, guiding grooves 111 are formed in both of the two side plates 112, and cooperating convex columns 221 protrude from both ends of the cooperating block 22. The two cooperating convex columns 221 are respectively in sliding cooperation with the guiding grooves 111 on the two side plates 112. In this way, both sides of the cooperating block 22 are limited, and its movement will be more stable.

[0048] Fixing convex columns 121 are provided on both sides of the fixing block 12, and fixing holes for cooperating with the fixing convex columns 121 are also formed in the two side plates 112 of the fixing base 11, thereby facilitating the connection between the fixing block 12 and the fixing base 11. After the fixing convex columns 121 extend into the fixing holes, the position of the fixing block 12 remains unchanged relative to the fixing base 11.

[0049] Understandably, in another embodiment, two guiding grooves 111 are provided, and the fixing convex columns 121 at both ends of the fixing block 12 can also extend into the guiding grooves 111 additionally formed on the two side plates 112 respectively. That is to say, while the engaging block 22 and the first connecting rod 311 move, the fixing block 12 and the second connecting rod 312 can also move correspondingly, so as to make the height adjustment action smoother. In this embodiment, it is equivalent to having two engaging blocks 22 moving towards each other. Correspondingly, external threads also need to be provided at the corresponding positions of the screw rod 21.

[0050] After both the fixing convex column 121 and the engaging convex column 221 extend into the guiding groove 111, both the fixing convex column 121 and the engaging convex column 221 can be connected to the bolt 50. The bolt 50 is screwed into the fixing convex column 121 and / or the engaging convex column 221, and the bolt head of the bolt 50 protrudes outside the guiding groove 111, and the bolt head abuts against the two side plates 112 of the fixing seat 11, so as to prevent the fixing convex column 121 and the engaging convex column 221 from disengaging from the guiding groove 111.

[0051] One end of the second connecting rod 312 away from the first connecting rod 311 is rotatably connected to the engaging convex column 221, and the other end is rotatably connected to the support shaft 33. One end of the second connecting rod 312 is rotatably connected to the fixing block 12, and the other end of the second connecting rod 312 is rotatably connected to the support shaft 33.

[0052] Further, the first link 311 includes two first connecting plates 3111 and a first reinforcing plate 3112. The two first connecting plates 3111 are connected by the first reinforcing plate 3112, and the two first connecting plates 3111 extend in parallel and are spaced apart. Two first connection holes 3113 are respectively formed in the two first connecting plates 3111. The two first connection holes 3113 are coaxially arranged and are both rotatably connected to the mating convex post 221. Two second connection holes 3114 are also respectively formed in the two first connecting plates 3111. The two second connection holes 3114 are coaxially arranged and are both rotatably connected to the support shaft 33. The second link 312 includes two second connecting plates and a second reinforcing plate. The two second connecting plates are connected by the second reinforcing plate, and the two second connecting plates extend in parallel and are spaced apart. Two third connection holes are respectively formed in the two second connecting plates. The two third connection holes are coaxially arranged and are both rotatably connected to the mating convex post 221. Two fourth connection holes are also respectively formed in the two second connecting plates. The two fourth connection holes are coaxially arranged and are both rotatably connected to the support shaft 33. In this way, the two parallel and extending first connecting plates 3111 can improve the structural strength of the first link 311, increase the load it can bear and its durability. The first reinforcing plate 3112 connects the two first connecting plates 3111 to form an integral structure of the first link 311. Moreover, the first reinforcing plate 3112 enables the two first connecting plates 3111 to jointly bear the load, and the stress can be transmitted between them through the first reinforcing plate 3112, thereby further improving the structural strength of the first link 311. Similarly, in the second link 312, setting the second link 312 as two second connecting plates and a second reinforcing plate can improve the structural strength of the second link 312, which will not be elaborated here.

[0053] Furthermore, the two first connecting plates 3111 and the second connecting plates are arranged in an alternating manner along the axial direction of the roller unit 32, and one first connecting plate 3111 is located between the two second connecting plates. In this way, the space along the axial direction of the roller unit 32 can be saved, and the space utilization rate can be improved.

[0054] The first connecting plate 3111 includes a first connecting portion 31111 and second connecting portions 31112 located at both ends of the first connecting portion 31111. The outer peripheral side of the second connecting portion 31112 is provided with an arc-shaped structure. The first reinforcing plate 3112 is connected to the two first connecting portions 31111 on the two first connecting plates 3111, and the first reinforcing plate 3112 is provided with an arc-shaped structure; the second connecting plate includes a third connecting portion and fourth connecting portions located at both ends of the third connecting portion. The outer peripheral side of the fourth connecting portion is provided with an arc-shaped structure. The second reinforcing plate is connected to the two third connecting portions on the two second connecting plates, and the second reinforcing plate is provided with an arc-shaped structure. In this way, the rotation of both ends of the arc-shaped first connecting plate 3111 (i.e., the two first connecting portions 31111) will be smoother, avoiding interference with other structures, and the arc-shaped first reinforcing plate 3112 and second reinforcing plate can also improve the structural strength of the first connecting rod 311 and the second connecting rod 312.

[0055] Preferably, in this embodiment, the structures of the first connecting rod 311 and the second connecting rod 312 are the same, that is, the structures of the four connecting rods of the two connecting rod units 31 on both sides are the same, so that they can be shared and interchanged, thereby reducing the process difficulty.

[0056] Specifically, taking the first connecting rod 311 as an example, in the first connecting plate 3111, a groove 31113 is further formed between the first connecting portion 31111 and the second connecting portion 31112. The groove 31113 facilitates the forming of the first reinforcing plate 3112 and contributes to the light weight of the structure.

[0057] In addition, the refrigerator height adjustment structure 101 includes a plurality of snap rings 40. The snap rings 40 are clamped on the outer sides of the axial directions of the rotation connections between the first connecting rod 311 and the second connecting rod 312 and the support shaft 33, the fixed convex column 121, and the mating convex column 221 to prevent the first connecting rod 311 and the second connecting rod 312 from disengaging from the fixed convex column 121 and the mating convex column 221. The snap rings 40 are also applied in the roller unit 32. When the roller unit 32 is provided with two rollers 321, the snap rings 40 are clamped on the axials of the two rollers 321 to prevent the two rollers 321 from displacing axially.

[0058] The present invention also provides a refrigerator 100, including the refrigerator height adjustment structure 101 as described above.

[0059] Compared with the prior art, in the present invention, the screw 21 is in threaded cooperation with the mating block 22. When the screw 21 rotates around its axis, it drives the mating block 22 to slide relative to the fixed assembly 10. While the mating block 22 moves, it drives the adjustment assembly 30 to move. The adjustment assembly 30 moves in the vertical direction in response to the movement of the mating block 22, thereby realizing the height adjustment of the refrigerator 100.

[0060] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0061] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
