[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0041] like Figures 1-10As shown, the adjustable foot structure provided by this utility model includes a first foot assembly 100, a fixing member 200, and a drive rod 300. The first foot assembly 100 and the fixing member 200 are spaced apart. The drive rod 300 extends from the first foot assembly 100 and connects to the fixing member 200, and the support height of the first foot assembly 100 is adjusted by the drive rod 300.

[0042] The first foot assembly 100 includes a base 101, a support leg 102 movably connected to the base 101 in the height direction, and a drive component 103 mounted on the base 101 and used to drive the support leg 102 to move in the height direction.

[0043] The base 101 is fixed to the bottom of the object to be supported, thereby supporting and bearing the object. The support leg 102 is supported on the bearing surface. When the support leg 102 moves in the height direction, it drives the base 101 to move closer to or further away from the bearing surface, so as to adjust the distance between the base 101 and the bearing surface.

[0044] The support leg 102 includes a support portion 102a for supporting on the bearing surface and a stud 102b connected to the support portion 101a and extending upward. The driving component 103 includes a nut 103a threadedly engaged with the stud 102b and a driving member for driving the nut 103a to rotate. The nut 103a is configured to rotate relative to the base 101, that is, the nut 103a will not move up and down relative to the base 101. Therefore, when the nut 103a rotates and drives the support leg 102 to move up and down, the nut 103a and the base 101 move up and down synchronously relative to the support leg 102 to adjust the distance between the base 101 and the bearing surface.

[0045] Specifically, the stud 102b has a non-circular cross-section, and the through hole 101a on the base 101 through which the stud 102b passes is a non-circular through hole adapted to the stud 102b. Therefore, when the nut 103a rotates, the engagement of the stud 102b with the non-circular through hole restricts the rotation of the stud 102b, allowing it to move only vertically relative to the nut 103a and the base 101, thereby adjusting the height of the base 101.

[0046] In one specific embodiment, a notch is provided on one side of the stud 102b along its circumference, so that the cross-section of the stud 102b is non-circular. Of course, this is not a limitation; in other embodiments, the cross-section of the stud 102b can also be set to an oblong shape or other shapes, as long as it can cooperate with the through hole 101a to restrict the rotation of the stud 102b relative to the base 101.

[0047] The base 101 is recessed downwards and has a first mounting cavity 101b for mounting the nut 103a, a second mounting cavity 101c for mounting the drive component and communicating with the first mounting cavity 101b, and a cover 101d for covering the first mounting cavity 101b. The upper and lower sides of the nut 103a abut against the cover 101d and the side of the first mounting cavity 101b opposite to the cover 101d, respectively, thereby restricting the vertical movement of the nut 103a relative to the base 101. When the support leg 102 moves up and down, the nut 103a and the base 101 move up and down synchronously relative to the support leg 102.

[0048] Specifically, the cover 101d is a sheet metal cover, which improves the stability of the connection between the cover 101d and the base 101. Of course, it is not limited to this.

[0049] The cover 101d has a spring piece 101d-1 on its circumference, and the base 101 has a locking block 101e that cooperates with the spring piece 101d-1. The connection between the cover 101d and the base 101 is achieved through the engagement between the spring piece 101d-1 and the locking block 101e. The structure is simple and easy to assemble and disassemble quickly.

[0050] The cover 101d is also provided with a non-circular hole 101d-2 through which the stud 102b passes and which is adapted to the cross-section of the stud 102b. The stud 102b passes through both the through hole 101a on the base 101 and the non-circular hole 101d-2 on the cover 101d, which can simultaneously restrict the rotation of the stud 102b relative to the base 101 from multiple parts, thereby enhancing the stability of the support leg 102 and thus enhancing the reliability of the adjustment of the first foot assembly 100.

[0051] The driving component includes a first gear 103b sleeved on the outside of the nut 103a and an operating component 103c that meshes with the first gear 103b to drive the first gear 103b to rotate. The nut 103a rotates synchronously with the first gear 103b. The nut 103a is driven to rotate by the meshing first gear 103b and the operating component 103c.

[0052] It is understood that the nut 103a is embedded in the middle of the first gear 103b, so that the nut 103a can rotate synchronously with the first gear 103b. Meanwhile, in embodiments with the first gear 103b, the first gear 103b is also housed within the first mounting cavity 101b, and the opposite sides of the first gear 103b are also configured to abut against the cover 101d and the side of the first mounting cavity 101b opposite to the cover 101d, which can prevent the first gear 103b from shifting under force and enhance the stability of the drive component 103.

[0053] The operating component 103c has an operating part 103c-1 for user operation. It is understood that those skilled in the art can, as needed, design the operating part 103c-1 as a prism with a non-circular cross-section, such as a hexagonal prism, to facilitate operation by the operator. Of course, this is not a limitation; those skilled in the art can also, as needed, design the operating part 331 as any other feasible structure with a non-circular cross-section, such as a triangular prism, elliptical prism, quadrilateral prism, etc.

[0054] In addition, those skilled in the art can, as needed, configure the operating part 103c-1 to have a non-circular cross-section trough, such as a hexagonal trough, a triangular trough, an elliptical trough, a rectangular trough, a cross-shaped trough, etc.

[0055] The operating part 103c-1 is exposed from the side of the seat 101 toward the fixing member 200, so that the drive rod 300 is connected to the operating part 103c-1 to realize the adjustment of the support leg 102.

[0056] In this embodiment, the first gear 103b is a bevel gear, and the operating member 103c includes a first bevel gear 103c-2 that meshes with the first gear 103b. The operating part 103c-1 is connected to the first bevel gear 103c-2, and the operating part 103c-1 and the first bevel gear 103c-2 are coaxially arranged. By operating the operating part 103c-1, the first bevel gear 103c-2 is driven to rotate, thereby driving the first gear 103b to rotate, which in turn causes the nut 103a to rotate, causing the support leg 102 to move up and down to adjust the height of the first base assembly 100.

[0057] In the embodiment where the operating part 103c-1 is exposed from the side of the seat 101 toward the fixing member 200, the second mounting cavity 101c is located on the side of the first mounting cavity 101b toward the fixing member 200, and the first bevel gear 103c-2 is located within the second mounting cavity 101c. The second mounting cavity 101c has an opening on the side toward the fixing member 200, thereby exposing the operating part 103c-1.

[0058] The first foot assembly 100 further includes a first roller 104 connected to the base 101, and the arrangement direction of the foot 102 and the first roller 104 forms an angle with the extension direction of the drive rod 300.

[0059] The first roller 104 facilitates the movement of the object to be supported on the first foot assembly 100. After the object is moved to the placement position, it is supported by the foot 102, thereby preventing the object from moving. Preferably, the arrangement direction of the foot 102 and the first roller 104 is perpendicular to the extension direction of the drive rod 300.

[0060] The fixing member 200 is spaced apart from the first foot assembly 100. The fixing member 200 has a slot 201, and the drive rod 300 is connected to the slot 201. One end of the drive rod 300 away from the fixing member 200 is connected to the operating part 103c-1. That is, one end of the drive rod 300 is connected to the operating part 103c-1, and the portion of the drive rod 300 closer to its other end is located in the slot 201, thus enabling the assembly of the drive rod 300. Therefore, by rotating the drive rod 300 at the position of the fixing member 200, the operating part 103c-1 is rotated via the drive rod 300, thereby adjusting the height of the foot 102.

[0061] The fixing member 200 includes a base plate 202 and an arc-shaped block 203 connected to the bottom of the base plate 202. The base plate 202 and the arc-shaped block 203 surround and form the slot 201. Specifically, the base plate 202 is used to fix the bottom of the object to be supported. A semi-circular groove is provided at the bottom of the base plate 202 to form the upper half of the slot 201. The arc-shaped block 203 surrounds and forms the lower half of the slot 201.

[0062] A U-shaped groove 202a is provided on the side of the substrate 202 away from the first foot assembly 100, and the U-shaped groove 202a is connected to the slot 201. After the drive rod 300 is inserted into the slot 201, the end of the drive rod 300 away from the operating part 103c-1 is located in the U-shaped groove 202a, thereby allowing the drive rod 300 to be operated on the side of the fixing member 200 away from the first foot assembly 100.

[0063] The arc-shaped block 203 is made of an elastic material, and it has a notch 203a for the drive rod 300 to enter the slot 201. When installing the drive rod 300, first connect one end of the drive rod 300 to the operating part 103c-1, and then insert the drive rod 300 into the slot 201 through the notch 203a. This allows for convenient assembly of the drive rod 300.

[0064] The notch 203a is angled α with respect to the vertical direction, meaning the notch 203a is tilted. This angle effectively prevents the drive rod 300 from falling out of the slot 201 after it is engaged with the notch 203a. Preferably, the angle α is between 30 and 60 degrees; more preferably, the angle α is 45 degrees.

[0065] Of course, the size of the notch 203a can also be set to be smaller than the diameter of the drive rod 300. Since the arc block 203 is made of elastic material, the drive rod 300 can squeeze the notch 203a to enter the slot 201, and can also effectively prevent the drive rod 300 from falling out of the slot 201.

[0066] The drive rod 300 extends from the first foot assembly 100 and connects to the fixing member 200. The first end of the drive rod 300 is connected to the operating part 103c-1, and the second end of the drive rod 300 is located within the U-shaped groove 202a. Rotating the second end of the drive rod 300 causes the operating part 103c-1 to rotate, thereby adjusting the height of the first foot assembly 100.

[0067] In one specific embodiment, the operating part 103c-1 has a rectangular or cross-shaped recess, and the first end of the drive rod 300 has a plug 303 for insertion into the recess of the operating part 103c-1. The operating part 103c-1 and the drive rod 300 rotate synchronously through the recess and the plug 303 adapted to it. Of course, this is not a limitation. It is understood that when the operating part 103c-1 is a non-circular cylinder, the plug 303 can be configured to have a recess adapted to the non-circular cylinder, as long as the plug 303 cooperates with the operating part 103c-1 to enable the operating part 103c-1 and the drive rod 300 to rotate synchronously.

[0068] The second end of the drive rod 300 is provided with an auxiliary operation part 302, which is located within the U-shaped groove 202a, meaning that the auxiliary operation part 302 is exposed from the side of the fixing member 200 away from the first base assembly 100. It is understood that the structure of the auxiliary operation part 302 can be configured to be the same as that of the operation part 103c-1, allowing the operator to operate the auxiliary operation part 302 using a wrench or screwdriver. However, this is not a limitation.

[0069] The drive rod 300 also includes a rod body 304 located between the auxiliary operation part 302 and the insertion block 303, and a limiting part 301 provided on the rod body 304. The limiting part 301 abuts against the arc-shaped block 203 to restrict the drive rod 300 from moving in the direction of the fixing member 200, thereby preventing the insertion block 303 from disengaging from the operation part 103c-1 and enhancing the stability of the connection between the drive rod 300 and the operation part 103c-1.

[0070] In this embodiment, the limiting part 301 is an annular baffle, and the diameter of the annular baffle 301 is larger than the diameter of the slot 201 so as to abut against the arc-shaped block 203. Of course, this is not a limitation, and the limiting part 301 may also be provided with at least two plate-shaped baffles spaced apart along the circumference of the drive rod 300.

[0071] When installing the drive rod 300, insert the insert block 303 into the operating part 103c-1, and then move the drive rod 300 so that the drive rod 300 is inserted into the slot 201 from the notch 203a, thereby allowing the auxiliary operating part 302 to enter the U-shaped groove 202a, and the limiting part 301 abuts against the arc-shaped block 203.

[0072] The limiting part 301 abuts against the arc-shaped block 203 to restrict the movement of the drive rod 300 in the direction of the fixing member 200, thereby preventing the insert block 303 from disengaging from the operating part 103c-1 and enhancing the stability of the connection between the drive rod 300 and the operating part 103c-1. The auxiliary operating part 302 enters the U-shaped groove 202a, thereby enabling the operation of the drive rod 300 on the side of the fixing member 200 away from the first base assembly 100. At the same time, the rod body 304 located between the limiting part 301 and the auxiliary operating part 302 is confined within the slot 201, preventing the drive rod 300 from moving radially thereafter and enhancing the stability of the drive rod 300.

[0073] In one embodiment, the fastener 200 is directly fixed to the bottom of the object to be supported by the base plate 202.

[0074] In another embodiment, the adjustable foot structure further includes a second foot assembly 400, through which the fastener 200 is fixed to the bottom of the object to be supported.

[0075] The second foot assembly 400 is spaced apart from the first foot assembly 100. The structure of the second foot assembly 400 can be the same as that of the first foot assembly 100, or it can adopt other foot structures. This article does not impose any specific restrictions on this.

[0076] In one specific embodiment, the second foot assembly 400 includes a fixed plate 401, an adjustable foot 402 connected to the fixed plate 401, and a second roller 403. The fixed plate 401 is used to fix to the bottom of the object to be supported, thereby bearing and supporting the object. The adjustable foot 402 is used to adjust the support height of the second foot assembly 400, and the adjustable foot 402 can adopt an existing foot structure. The second roller 403 facilitates the movement of the object to be supported on the second foot assembly 400.

[0077] The fixing member 200 is fixed to the bottom of the fixing plate 401, and the fixing member 200 is located between the adjustable foot 402 and the second roller 403.

[0078] The substrate 202 is provided with a fixing part 202b, and a fixing screw hole is provided in the fixing part 202b; a screw 401a is provided on the fixing plate 401, which connects to the fixing screw hole, and the fixing plate 200 is fixed to the fixing plate 401 through the fixing screw hole and the screw 401a. The fixing part 202b is columnar and perpendicular to the substrate 202, and there are two fixing parts 202b. The slot 201 is located between the two fixing parts 202b, thereby enhancing the fixing reliability of the fastener 200.

[0079] An insertion part 202c is provided on the side of the substrate 202 away from the first foot assembly 100, and an insertion groove 401b is provided on the fixing plate 401. The insertion part 202c is inserted into the insertion groove 401b, thereby positioning the installation of the fixing member 200.

[0080] The insertion portion 202c extends from the substrate 202 in a direction away from the first foot assembly 100. Two insertion portions 202c are provided, and the two insertion portions 202c and the substrate 202 together form the U-shaped groove 202a. The fixing plate 401 has an opening 401d on the side away from the first foot assembly 100, and the insertion groove 401b is provided on both sides of the opening 401d. When the insertion portion 202c is inserted into the insertion groove 401b, the U-shaped groove 202a is located within the opening 401d, thereby exposing the auxiliary operation portion 302 from the opening 401d for operator access.

[0081] The top of the substrate 202 is also provided with a positioning post 202d, and the fixing plate 401 is provided with a positioning hole 401c corresponding to the positioning post 202d. The positioning post 202d is inserted into the positioning hole 401c, thereby positioning the installation of the fixing member 200.

[0082] like Figure 11 As shown, this utility model also provides a household appliance. The adjustable foot structure is fixed to the bottom of the household appliance to place it on a supporting surface. The level of the household appliance can be adjusted by adjusting the height of the adjustable foot structure, thereby avoiding the tilting problem caused by the flatness of the supporting surface, achieving horizontal placement, which is safe and reliable.

[0083] The household appliances mentioned include, but are not limited to, refrigerators, freezers, freezers, washing machines, dryers, and washer-dryer combos. The following explanation uses refrigerators as an example, but it is not a limitation.

[0084] The adjustable foot structure is fixed to the bottom of the refrigerator, that is, the first foot assembly 100 and the fixing member 200 are spaced apart at the bottom of the refrigerator, with the fixing member 200 located on the front side of the refrigerator. Thus, even if the first foot assembly 100 is located on the rear side of the refrigerator, since the drive rod 300 extends from the first foot assembly 100 and connects to the fixing member 200, the height of the first foot assembly 100 can be adjusted by operating the drive rod 300 on the side where the fixing member 200 is located. In other words, the height of the first foot assembly 100 can be adjusted from the front side of the refrigerator, which is convenient and quick. The length of the drive rod 300 can be adaptively adjusted according to the distance of the first foot assembly 100 from the front side of the refrigerator.

[0085] When the fixing member 200 is fixed to the second foot assembly 400, it can be understood that the first foot assembly 100 is the rear foot of the refrigerator, and the second foot assembly 400 is the front foot of the refrigerator. Both the first foot assembly 100 and the second foot assembly 400 can be adjusted from the front of the refrigerator. The adjustable foot structure has two sets, located on the left and right sides of the refrigerator, thereby enabling height adjustment of the four corners of the refrigerator, which facilitates quick leveling of the refrigerator.

[0086] In summary, this invention configures the drive rod 300 to extend from the first foot assembly 100 and connect to the fixing member 200, thereby enabling the adjustment of the drive rod 300 at the location of the fixing member 200 to achieve height adjustment of the first foot assembly 100, i.e., enabling long-distance adjustment of the first foot assembly 100. Thus, when this adjustable foot structure is installed at the bottom of the refrigerator, only the fixing member 200 needs to be positioned on the front side of the refrigerator; even if the first foot assembly 100 is far from the front side of the refrigerator, its height can still be adjusted from the front side of the refrigerator, providing convenience and ease.

[0087] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0088] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
