[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a common household product that keeps food or other items at a constant low temperature.

[0003] In existing technologies, refrigerators are often transported using either a fixed structure or a roller structure.

[0004] Fixed structures not only cause difficulties and time-consuming handling during transportation, but also pose safety threats to the personnel handling the refrigerator, risk damage to the refrigerator itself, and leave scratches and other marks in the transportation environment.

[0005] The roller structure simplifies handling time and saves effort by installing rollers at the bottom of the refrigerator. However, if the rollers are always at the bottom of the refrigerator, it will cause the refrigerator to be unstable in position. Removing the rollers will add more steps to the disassembly process, which is time-consuming and laborious.

[0006] Therefore, there is an urgent need to provide a new solution to address the defects and shortcomings of the existing technologies. Utility Model Content

[0031] [First Embodiment]

[0032] like Figure 1-5The image shows a spherical refrigerator base provided in the first embodiment of this utility model, including a base plate 1 fixedly connected to the bottom of the refrigerator. A roller assembly 2 is movably mounted on one side of the bottom of the base plate 1, and a ball assembly 3 is movably mounted on the other side of the bottom of the base plate 2. The extension height of the ball assembly 3 at the bottom of the base plate 1 is adjustable. This allows the refrigerator to be moved and its position adjusted by simply adjusting and decreasing the extension height of the ball assembly so that the ball assembly is no longer in contact with the ground. When the refrigerator needs to be positioned, the extension height of the ball assembly is increased accordingly so that the ball assembly is in contact with the ground, thus achieving the positioning effect of the refrigerator at the current position.

[0033] like Figure 2 As shown, in this embodiment, the substrate 1 has several fixing holes 11 inside that are fixedly connected to the bottom of the refrigerator. The fixing member passes through the fixing holes 11 to fix the substrate 1 to the bottom of the refrigerator. The substrate 1 has roller holes 12 corresponding to the position of roller assembly 2 and roller holes 13 corresponding to the position of ball assembly 3 inside. The inner wall of the ball hole 13 is provided with internal threads. The roller hole 12 provides an observation window and deformation space for roller assembly 2, while the ball hole 13 is used to achieve a threaded connection with the ball assembly 3 to achieve a fixed connection between the ball assembly 3 and the substrate 1.

[0034] like Figure 1 and Figure 3-4 As shown, the two sides of the substrate 1 are fixedly connected to the side edges 14, which cover the outer edge of the roller assembly 2 and the outer edge of the ball assembly 3. A pivot hole 141 is provided inside the side edge 12, so as to provide mounting support for the roller assembly 2 and facilitate the operation and adjustment of the ball assembly 3.

[0035] like Figure 5 As shown, the roller assembly 2 in this embodiment includes a rotating shaft 21 and a roller 22. The rotating shaft 21 is fixed inside the rotating shaft hole 141, and the roller 22 is movably sleeved on the outer periphery of the rotating shaft 21, thereby enabling the roller 22 to rotate relative to the outer periphery of the rotating shaft 21.

[0036] In this embodiment, the ball assembly 3 includes an adjusting member 31. The top of the adjusting member 31 is fixedly connected to the ball hole 13. An operating member 32 is threadedly connected to the outside of the adjusting member 31. A ball 33 is housed inside the adjusting member 31. The height position of the operating member 32 on the outside of the adjusting member 31 can be adjusted by manipulating the operating member 32 on the threaded outside of the adjusting member 31.

[0037] like Figure 5As shown, the adjusting member 31 in this embodiment includes an upper small-diameter portion 311 and a lower large-diameter portion 312 formed as one piece. The outer wall of the small-diameter portion 311 is provided with a small-diameter external thread that engages with the internal thread of the inner wall of the ball bearing hole 13, so as to fix the adjusting member 31 inside the ball bearing hole 13. The outer wall of the large-diameter portion 312 is provided with a large-diameter external thread that engages with the operating member 32, so as to adjust the height position of the operating member 32 on the outside of the adjusting member 31.

[0038] To further facilitate the thread adjustment effect, the operating part 32 is fixed with an internal thread part 321, and the inner wall of the internal thread part 321 is provided with an internal thread that mates with the large-diameter external thread.

[0039] As a further preferred embodiment, a limiting part 34 is provided at the bottom of the adjusting member 31 to limit the rolling ball 33, thereby ensuring that the rolling ball 33 is confined within the inner cavity of the adjusting member 31 when it rolls. Furthermore, a ball bearing 35 is filled between the outer edge of the rolling ball 33 and the inner cavity of the adjusting member 31, thereby further improving the rolling smoothness and fluidity of the rolling ball 33.

[0040] The specific working process of this embodiment is as follows:

[0041] When it is necessary to move the refrigerator, simply adjust the height of the operating part 32 on the outside of the adjusting part 31 by means of the threaded connection, so that the operating part 32 rises on the outside of the adjusting part 31 until it is in the high position, thereby making the roller assembly 3 disengage from the ground. At this time, the movement and position adjustment of the refrigerator can be achieved by means of the roller assembly 2 and the ball assembly 3.

[0042] When the refrigerator needs to be positioned, the height of the operating part 32 on the outside of the adjusting part 31 needs to be adjusted by threaded connection, so that the operating part 32 is lowered on the outside of the adjusting part 31 until it is in a low position, so that the roller assembly 3 is in direct contact with the ground. At this time, due to the large friction between the operating part 32 and the ground, the movement and position adjustment of the refrigerator cannot be achieved by the roller assembly 2, thus achieving the positioning of the refrigerator in the current position.

[0043] To further increase the service life of the operating component 32 and reduce its manufacturing cost, the operating component 32 is preferably made of wear-resistant plastic material, and has textured surfaces on its outer side to facilitate user operation.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
