[0027] Reference Figures 1 to 7 As shown, the adjustable foot assembly of the present invention includes a fixing plate 100 , a first supporting foot 200 , an adjusting screw 300 and a telescopic member 400 .

[0028] The first supporting foot 200 is located below the fixing plate 100, the adjusting screw 300 is threadedly connected to the fixing plate 100, the adjusting screw 300 extends from the top of the fixing plate 100 to the first supporting foot 200, the adjusting screw 300 is rotatably connected to the first supporting foot 200, and the adjusting screw 300 or the first supporting foot 200 is provided with a limiter for limiting the axial movement of the first supporting foot 200 along the adjusting screw 300; or, the bottom end of the adjusting screw 300 abuts against the first supporting foot 200, and the fixing plate 100 and the first supporting foot 200 are connected through a telescopic member 400. When it is necessary to adjust the height of the adjustable foot assembly, the adjusting screw 300 is rotated to make it move up and down along the fixing plate 100, so as to adjust the distance between the fixing plate 100 and the first supporting foot 200, and the telescopic member 400 is synchronously telescoped with the change of the distance between the fixing plate 100 and the first supporting foot 200, thereby realizing the height adjustment of the adjustable foot assembly.

[0029] Among them, the fixing plate 100 is provided with a through hole 101 and a fixing nut 102 coaxial with the through hole 101. The fixing nut 102 is fixed under the fixing plate 100 to hide the fixing nut 102. The adjusting screw 300 passes through the through hole 101 and is threadedly connected to the fixing nut 102. By adding the fixing nut 102, there is no need to open a screw hole on the fixing plate 100, thereby effectively reducing the thickness of the fixing plate 100.

[0030] The first supporting foot 200 includes a top plate 201, side plates 202 extending downward from two sides of the top plate 201 that are opposite to each other, and a bottom wheel 203 rotatably installed between the side plates 202. The bottom wheel 203 is rotatably installed between the two side plates 202 via a pin shaft. The bottom wheel 203 is provided to facilitate the movement of the adjustable foot assembly.

[0031] Reference Figure 1 and Figure 2 In one type of embodiment, the adjusting screw 300 is rotatably connected to the first supporting foot 200 , and the connection and spacing adjustment between the fixing plate 100 and the first supporting foot 200 are achieved through the adjusting screw 300 .

[0032] The adjusting screw 300 passes through the through hole 101 and is threadedly connected to the fixing nut 102. The adjusting screw 300 is rotatably connected to the top plate 201 of the first supporting foot 200. The top plate 201 is provided with a rotating hole, and the adjusting screw 300 passes through the rotating hole. The limiting member is a limiting disc 301 provided on the adjusting screw 300. There are two groups of limiting discs 301. The top plate 201 is located between the two groups of limiting discs 301, and the diameter of the limiting disc 301 is greater than the diameter of the rotating hole. Rotating the adjusting screw 300 causes the adjusting screw 300 to move up and down along the fixing nut 102, thereby driving the first supporting foot 200 to move up and down, and the distance between the fixing plate 100 and the first supporting foot 200 increases or decreases, thereby realizing the support height adjustment of the adjustable foot assembly.

[0033] In order to facilitate the rotation of the adjusting screw 300 , a non-circular rotation hole is opened at the top of the adjusting screw 300 , and the adjusting screw 300 is rotated by using an external tool such as a wrench.

[0034] Specifically, when the adjustable foot assembly needs to be raised, the adjusting screw 300 is rotated so that the adjusting screw 300 moves downward along the fixing nut 102, thereby driving the first supporting foot 200 to move in a direction away from the fixing plate 100, and the distance between the fixing plate 100 and the first supporting foot 200 increases, and the supporting height of the adjustable foot assembly increases;

[0035] When the adjustable base assembly needs to be lowered, the adjusting screw 300 is rotated so that the adjusting screw 300 moves upward along the fixing nut 102, thereby driving the first supporting foot 200 to move toward the fixing plate 100, and the distance between the fixing plate 100 and the first supporting foot 200 is reduced, and the supporting height of the adjustable base assembly is reduced.

[0036] Reference Figures 3 to 5 In another embodiment, the bottom end of the adjusting screw 300 abuts against the first supporting foot 200, and the distance between the fixing plate 100 and the first supporting foot 200 is adjusted by the adjusting screw 300, and the connection between the fixing plate 100 and the first supporting foot 200 is achieved by the telescopic member 400, thereby facilitating the disassembly and replacement of the adjusting screw 300 and at the same time helping to increase the stability of the adjustable foot assembly.

[0037] The adjusting screw 300 passes through the through hole 101 and is threadedly connected to the fixing nut 102. The bottom end of the adjusting screw 300 abuts against the top of the top plate 201 of the first supporting foot 200. The telescopic member 400 is provided with two groups. The adjusting screw 300 is located between the two groups of telescopic members 400. When the adjusting screw 300 is rotated to adjust the distance between the fixing plate 100 and the first supporting foot 200, the telescopic member 400 is synchronously extended and retracted.

[0038] Reference Figure 3 In one embodiment, the telescopic member 400 is a telescopic rod 401 connected between the fixed plate 100 and the first supporting leg 200, the top end of the telescopic rod 401 is fixed to the bottom of the fixed plate 100, and the bottom end of the telescopic rod 401 is fixed to the top of the top plate 201, and the telescopic rod 401 includes an inner rod and an outer rod, and the inner rod is sleeved in the outer rod.

[0039] When the adjustable foot assembly needs to be raised, the adjusting screw 300 is rotated so that the adjusting screw 300 moves downward along the fixing nut 102, thereby pushing the first supporting foot 200 to move in a direction away from the fixing plate 100, the inner rod extends from the outer rod, the distance between the fixing plate 100 and the first supporting foot 200, and the length of the telescopic rod 401 increase synchronously, and the supporting height of the adjustable foot assembly increases;

[0040] When the adjustable foot assembly needs to be lowered, the adjusting screw 300 is rotated so that the adjusting screw 300 moves upward along the fixing nut 102, and the first supporting foot 200 synchronously moves upward under pressure to maintain abutment with the adjusting screw 300, the inner rod is retracted into the outer rod, and the distance between the fixing plate 100 and the first supporting foot 200 and the length of the telescopic rod 401 are synchronously reduced, and the supporting height of the adjustable foot assembly is reduced.

[0041] Reference Figure 4 and Figure 5 In another embodiment, the telescopic member 400 is a hinge member 402 hinged between the fixed plate 100 and the first supporting leg 200, and the hinge member 402 includes a first hinge plate 402a and a second hinge plate 402b, one end of the first hinge plate 402a is hinged to the fixed plate 100, and the other end is hinged to the second hinge plate 402b, and one end of the second hinge plate 402b away from the first hinge plate 402a is hinged to the first supporting leg 200.

[0042] Specifically, the first hinge plate 402a is H-shaped and has four hinge parts. The first hinge plate 402a and the second hinge plate 402b have the same structure. The first mounting plates 103 are extended downward on the two opposite sides of the fixed plate 100. The two hinge parts located at the top of the first hinge plate 402a are hinged between the first mounting plates 103 through hinge shafts. The two hinge parts located at the bottom of the first hinge plate 402a are hinged to the two hinge parts located at the top of the second hinge plate 402b through hinge shafts. The second mounting plates 204 are extended upward on the two opposite sides of the top plate 201. The two hinge parts located at the bottom of the second hinge plate 402b are hinged between the second mounting plates 204 through hinge shafts.

[0043] When the adjusting screw 300 is rotated so that the adjusting screw 300 moves up and down along the fixing nut 102, the first supporting leg 200 is displaced synchronously, and the first hinge plate 402a and the second hinge plate 402b are rotated synchronously with the movement of the first supporting leg 200, and the first hinge plate 402a and the second hinge plate 402b are folded or unfolded.

[0044] Furthermore, the adjustable base assembly also includes a second supporting foot 500 located on the side of the fixing plate 100 away from the first supporting foot 200, and the second supporting foot 500 includes a base stud 501 fixed on the fixing plate 100 and a base 502 threadedly connected to the bottom end of the base stud 501.

[0045] After the first support leg 200 is adjusted to the right position, the base leg 502 can be rotated for secondary adjustment and positioning. When the first support leg 200 contacts the bearing surface (such as the ground), it is convenient for the object carried thereon to move; when the second support leg 500 contacts the bearing surface (such as the ground), the object carried thereon is fixed to prevent it from moving again after leveling. The height of the first support leg 200 is adjustable, and the adjustment range of the base leg assembly is not restricted by the first support leg 200, so as to meet the height adjustment of different bearing surfaces.

[0046] The first fixing plate 100 further includes a connecting plate 104 located on the top thereof. The connecting plate 104 is provided with fixing holes. The adjustable foot assembly is installed at the bottom of the object to be carried through the connecting plate 104 .

[0047] The present invention also provides a refrigerator, which includes the above-mentioned adjustable foot assembly. In this embodiment, the adjustable foot assembly is fixed to the front side of the refrigerator through a connecting plate 104, thereby solving the leveling problem when the bearing surface is higher in the front and lower in the back, preventing the refrigerator from tilting backward and affecting the normal use of the user.

[0048] In summary, the present invention realizes height adjustment of the first supporting foot 200 by means of the adjusting screw 300 threadedly connected to the fixing plate 100, so that the adjustment range of the adjustable base assembly is not restricted by the inherent height of the first supporting foot 200, so as to adapt to the leveling installation of different bearing surfaces, and realize the movement and fixation of the refrigerator in combination with the second supporting foot 300.
