Fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present invention. Fig. 2 is a schematic structural view of an adjustment foot 300 and a roller mechanism 200 according to an embodiment of the invention.

Referring to fig. 1 and 2, the refrigerator provided in this embodiment includes a refrigeration box 100, and the refrigeration box 100 is provided therein with a compressor, a condenser, an evaporator, and other components to implement a refrigeration function thereof.

A plurality of roller mechanisms 200 and a plurality of adjustment feet 300 are provided at the bottom of the refrigeration cabinet 100. The moving function of the refrigerating cabinet 100 is realized by the contact of the roller mechanism 200 with the ground, and the supporting function of the refrigerating cabinet 100 is realized by the contact of the bottom of the adjusting foot 300 with the ground.

Specifically, in some embodiments, four roller mechanisms 200 may be provided, which are respectively installed at four corners of the bottom of the refrigeration cabinet 100, two roller mechanisms 200 at the front side may be provided as universal rollers, which are rotatably connected to the bottom of the refrigeration cabinet 100 by vertically distributed rotating shafts to perform horizontal rotation, so as to change the advancing direction of the refrigeration cabinet 100, and two roller mechanisms 200 at the rear side may be provided as fixed rollers, which are fixedly connected to the bottom of the refrigeration cabinet 100 and roll along with the advancing of the refrigeration cabinet 100; through with universal gyro wheel and fixed gyro wheel complex mode, simplify the structure of device, reduce the manufacturing cost of refrigerator.

Of course, four adjusting feet 300 may be provided and installed at four corners of the bottom of the refrigeration box 100, so that the heights of the four corners can be adjusted, which is not limited herein.

Moreover, in other embodiments, adjustment foot 300 and roller mechanism 200 may be integrated (as shown in fig. 2); so as to reduce the volume, save the space of the bottom of the refrigerator and improve the convenience of push-pull movement and height adjustment of people.

Fig. 2 is a schematic structural view of an adjustment foot 300 and a roller mechanism 200 according to an embodiment of the invention. Fig. 3 is a side view of fig. 2.

Referring to fig. 2 and 3, the adjusting foot 300 includes a fixing plate 3 installed at the bottom of the refrigeration case 100, a supporting member 4 located below the fixing plate 3, a telescopic mechanism 5 having upper and lower ends respectively connected to the fixing plate 3 and the supporting member 4, and a swing mechanism 6 having upper and lower ends respectively hinged to the fixing plate 3 and the supporting member 4.

The fixing plate 3 serves as a mounting base for mounting the entire adjusting foot 300 on the bottom surface of the refrigeration cabinet 100, as by means of a fixing hole 31 provided in the fixing plate 3, in cooperation with a screw for reliable fixing.

The bottom of the support 4 is provided with a support surface by which it is supported in contact with the ground.

The telescopic mechanism 5 comprises a telescopic assembly 51 which can be extended and retracted up and down and an adjusting assembly 52 which is connected with and drives the telescopic assembly 51 to extend and retract.

Wherein, the upper and lower both ends of flexible subassembly 51 are connected fixed plate 3 and support piece 4 respectively, and in the in-process that flexible subassembly 51 goes on stretching out and drawing back from top to bottom, support piece 4 can move up and down for the bottom surface of fixed plate 3 or refrigeration box 100, changes and adjusts the relative height of support piece 4 for refrigeration box 100, realizes the regulation of height from top to bottom. Meanwhile, in the process that the supporting piece 4 moves up and down, the relative height between the supporting surface and the bottom surface of the roller mechanism 200 can be adjusted, so that the supporting surface is higher or lower than the bottom surface of the roller mechanism 200; when the height of the supporting surface is lower than the height of the bottom surface of the roller mechanism 200, the roller mechanism 200 is suspended, and the refrigeration box 100 realizes the supporting function through the supporting surface of the supporting piece 4; when the height of the supporting surface is higher than the height of the bottom surface of the roller mechanism 200, the supporting member 4 is suspended and the roller mechanism 200 is grounded, so that the refrigeration box 100 can move through the roller mechanism 200.

The adjusting assembly 52 is connected to the telescopic assembly 51, and can adopt electric control, physical transmission and other modes to provide power for the telescopic assembly 51 and drive and control the telescopic assembly 51 to extend and retract up and down.

Meanwhile, in the process that the support member 4 moves up and down, the support member 4 rotates and swings by taking the swing mechanism 6 as a swing arm, the motion track of the support member 4 is limited, namely the motion of the support member 4 is guided by the swing mechanism 6, so that the motion of the support member 4 is more stable.

When adjusting footing 300 and realizing the support function to in-process adjusting the relative height of support piece 4 for refrigeration box 100 bottom surface, the holding surface of support piece 4 bottom supports all the time and leans on subaerial, does not take place relative slip with ground, consequently can not lead to the fact wearing and tearing to ground and support piece 4 itself, thereby be different from the tradition and adopt the rotatory adjusting screw mode, provide a different regulation structure, solved the easy problem on ground that wears out of refrigerator footing when rotatory.

in the refrigerator, the height adjusting and moving functions are realized by matching the adjusting bottom feet 300 with the roller mechanism 200; wherein the adjusting foot 300 comprises a fixing plate 3, a supporting member 4, a telescopic mechanism 5 and a swinging mechanism 6; is connected to the bottom of the refrigeration box body 100 through a fixing plate 3 and is supported by the contact of the supporting surface of a supporting piece 4 and the ground; in the telescopic mechanism 5, a telescopic component 51 is respectively connected with the fixed plate 3 and the support member 4, and an adjusting component 52 drives the telescopic component 51 to extend and retract up and down, so that the support member 4 extends and retracts up and down relative to the refrigeration box 100, thereby changing the height of the support member 4 and realizing the height adjusting function; two ends of the swing mechanism 6 are respectively hinged with the fixed plate 3 and the support piece 4, and the swing mechanism 6 is used as a swing arm to perform rotary swing in the process of up-and-down stretching of the support piece 4, so that the movement of the support piece 4 is guided and is more stable; the height of the supporting surface of the supporting member 4 can be adjusted between a height higher and a height lower than the bottom end of the roller mechanism 200 within the rotation range of the supporting member 4, thereby achieving a moving function in cooperation with the roller mechanism 200. Meanwhile, the support piece 4 mechanically supports the fixed plate 3 and the refrigeration box body 100 through the swing mechanism 6 and the telescopic mechanism 5 respectively, so that the support stability of the support piece 4 on the refrigeration box body 100 is improved. When the supporting member 4 is adjusted up and down relative to the refrigerating box 100, the supporting surface is always in contact with the ground and does not need to slide relatively, so that friction is not generated, the supporting member 4 and the ground are not abraded, and the problem that the ground is easily abraded when the feet of the refrigerator rotate is solved.
