[0027] Reference Figures 1 to 6 The adjustable foot structure shown can be connected to the bottom of a household appliance to adjust the height or level the household appliance. This article takes a refrigerator as an example to explain the structure and function of the adjustable foot structure in detail.

[0028] The adjustable foot structure includes: a base plate 100, a limiter 200, and an adjustment bolt 300 for adjusting the support height.

[0029] The base plate 100 is used to connect with the refrigerator, and may be a bottom plate of the refrigerator, or may be an independent structure connected with the bottom of the refrigerator.

[0030] The base plate 100 includes a bottom plate 101 and a connecting plate 102, wherein the connecting plate 102 is fixedly mounted on the top of the bottom plate 101, and the two can be fixed by welding or bolting. The stopper 200 is connected to the bottom of the bottom plate 101, and the adjusting bolt 300 is threadedly connected to the connecting plate 102, and the height adjustment is achieved by rotating the adjusting bolt 300.

[0031] In this embodiment, a first threaded hole is formed on the bottom plate 101, and a second threaded hole is formed on the connecting plate 102. The centers of the first threaded hole and the second threaded hole are located on the same axis. The stopper 200 is threadedly connected to the first threaded hole, and the adjusting bolt 300 passes through the stopper 200 and is threadedly connected to the second threaded hole.

[0032] The limiting member 200 is used to limit the displacement of the adjusting bolt 300 in the height direction. A limiting cavity 201 is provided inside the limiting member 200. A limiting portion 301 is provided outside the adjusting bolt 300. The limiting portion 301 is located inside the limiting cavity 201. When the adjusting bolt 300 is rotated, the limiting portion 301 moves along the height direction inside the limiting cavity 201. When the limiting portion 301 moves to the top of the limiting cavity 201, the adjusting bolt 300 cannot continue to rotate upward; when the limiting portion 301 moves to the bottom of the limiting cavity 201, the adjusting bolt 300 cannot continue to rotate downward.

[0033] Furthermore, the limiting member 200 includes a first limiting block 202 and a second limiting block 203. The first limiting block 202 and the second limiting block 203 are semicircular in shape. The first limiting block 202 has a first groove 202a in the middle, and a semicircular ring is dug out of the first limiting block 202 to form the first groove 202a. The second limiting block 203 has a second groove 203a in the middle, and a semicircular ring is dug out of the second limiting block 203 to form the second groove 203a.

[0034] The first limit block 202 and the second limit block 203 are assembled together to form a circular ring, the inner diameter of which is larger than the outer diameter of the adjusting bolt 300, and the adjusting bolt 300 passes through the circular ring and is threadedly connected to the connecting plate 102; the first groove 202a and the second groove 203a are assembled together to form the limit cavity 201, and the limit cavity 201 is circular, the diameter of which is larger than the inner diameter of the circular ring, and the limit portion 301 is located in the limit cavity 201 and can only move up and down in the limit cavity 201.

[0035] The first limiting block 202 includes a first limiting portion 202b and a first threaded connection portion 202c located at the top of the first limiting portion 202b, and the first groove 202a is opened in the first limiting portion 202a; the second limiting block 203 includes a second limiting portion 203b and a second threaded connection portion 203c located at the top of the second limiting portion 203b, the second groove 203b is opened in the second limiting portion 203b, and the first threaded connection portion 202c and the second threaded connection portion 203c are provided with external threads.

[0036] When the first limiting block 202 and the second limiting block 203 are assembled together, the first limiting portion 202b and the second limiting portion 203b are aligned to form a limiting portion, and the limiting cavity 201 is formed inside the two; the first threaded connection portion 202c and the second threaded connection portion 203c are aligned, and the external thread of the first threaded connection portion 202c and the external thread of the second threaded connection portion 203c maintain continuity to form a complete threaded connection portion, and the limiting member 200 is threadedly connected to the bottom of the base plate 101 through the threaded connection portion.

[0037] In this embodiment, the outer diameters of the first limiting portion 202b and the second limiting portion 202c are the same, the outer diameters of the first threaded connection portion 202c and the second threaded connection portion 203c are the same, and the outer diameter of the first limiting portion 202b is greater than the outer diameter of the first threaded connection portion 202c. After the first limiting block 202 and the second limiting block 203 are assembled, the outer diameter of the limiting portion is greater than the outer diameter of the threaded connection portion, and when the limiting member 200 is connected to the bottom plate 101 through the threaded connection portion, the limiting portion abuts against the bottom of the bottom plate 101.

[0038] Furthermore, a positioning block is provided on the first limit block 202, and a positioning groove is provided on the second limit block 230, and the positioning block is located in the positioning groove. Specifically, the positioning block is provided at the top of the first threaded connection part 202c, and is a protruding block facing the second threaded connection part 203c. The positioning groove is provided at the top of the second threaded connection part 203c. When the first limit block 202 and the second limit block 203 are assembled, the positioning block is inserted into the positioning groove, thereby ensuring the accuracy of the assembly of the first limit block 202 and the second limit block 203.

[0039] Of course, in other embodiments, a positioning groove may be provided on the first limit block 202, and a positioning block may be provided on the second limit block 230; or a positioning block and a positioning groove may be provided on the first limit block 202 at the same time, and a positioning groove and a positioning block matching the first limit block 202 may be provided on the second limit block 203.

[0040] The adjusting bolt 300 passes through the stopper 200 and is threadedly connected to the connecting plate 100. The adjusting bolt 300 includes a threaded portion and an adjusting portion connected to the bottom of the threaded portion. The adjusting portion is a non-circular structure, so that the adjusting bolt 300 can be easily rotated by an external tool such as a wrench to adjust the height. At the same time, the adjusting portion contacts the bearing surface (such as the ground) to provide support for the refrigerator.

[0041] Furthermore, the limiting portion 301 is located outside the threaded portion. In this embodiment, the limiting portion 301 is a limiting ring, the diameter of which is larger than the inner diameter of the circular ring and smaller than the diameter of the limiting cavity 201. When the adjusting bolt 300 is rotated, the limiting ring is limited to move up and down in the limiting cavity 201.

[0042] A reinforcing iron is further provided between the limiting member 200 and the bottom plate 101 , and the reinforcing iron is used to strengthen the supporting strength of the base plate 100 to prevent the connection between the base plate 100 and the adjusting bolt 300 from being deformed.

[0043] When installing the adjustable foot structure, the first limiting block 202 and the second limiting block 203 are placed outside the threaded portion of the adjusting bolt 300, and the limiting member 200 composed of the first limiting block 202 and the second limiting block 203 surrounds the threaded portion, and the limiting portion 301 is located in the limiting cavity 201;

[0044] The limiting member 200 is passed through the reinforcing iron, and the threaded connection portion of the limiting member 200 is rotated and installed in the first threaded hole on the bottom plate 101, and the threaded portion of the adjusting bolt 300 is rotated and installed in the second threaded hole on the connecting plate 102, until the limiting portion of the limiting member 200 abuts against the reinforcing iron;

[0045] After installation, the support height can be adjusted by rotating the adjusting bolt 300. When the adjusting bolt 300 is rotated to make the limit portion 301 move upward along the limit cavity 201, the distance between the adjusting portion and the substrate 100 is reduced, and the support height of the adjustable foot structure is reduced. The minimum support height is when the limit portion 301 moves to the top of the limit cavity 201; when the adjusting bolt 300 is rotated to make the limit portion 301 move downward along the limit cavity 201, the distance between the adjusting portion and the substrate 100 is increased, and the support height of the adjustable foot structure is increased. The maximum support height is when the limit portion 301 moves to the bottom of the limit cavity 201.

[0046] The limiting member 200 and the adjusting bolt 300 are detachably fixed to the base plate 100 , so that any one of the limiting member 200 and the adjusting bolt 300 can be easily replaced.

[0047] The utility model also provides a refrigerator, which comprises the above-mentioned adjustable foot structure. The adjustable foot structure can be installed on the front side and / or the rear side of the refrigerator to achieve horizontal adjustment of the refrigerator.

[0048] In summary, the utility model has a simple structure, low cost, and is easy to assemble and adjust. At the same time, the limiting cavity 201 in the limiting member 200 limits the adjustment range of the adjusting bolt 300 to prevent over-adjustment.
