Description

Technical Field

[0001] This utility model belongs to the technical field of household appliance accessories, specifically relating to a columnar refrigerator base. Background Technology

[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

[0007] In order to overcome the defects and shortcomings of the existing technology, this utility model provides a columnar refrigerator base.

[0008] The technical solution provided by this utility model is as follows:

[0009] A columnar refrigerator foot includes a base plate fixedly connected to the bottom of the refrigerator. A roller assembly is movably mounted on one side of the bottom of the base plate, and a roller assembly is movably mounted on the other side of the bottom of the base plate. The working state of the roller assembly at the bottom of the base plate is adjustable. When the roller assembly is unlocked, the refrigerator foot can move; when the roller assembly is locked, the refrigerator foot cannot move.

[0034] [First Embodiment]

[0035] like Figure 1-6 The image shown is a columnar refrigerator base provided in the first embodiment of this utility model, as follows: Figure 1 As shown, the system includes 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 roller assembly 3 is movably mounted on the other side of the bottom of the base plate 1. The working state of the roller assembly 3 at the bottom of the base plate 1 is adjustable. When the roller assembly 3 is unlocked, the refrigerator feet can move; when the roller assembly 3 is locked, the refrigerator feet cannot move. Thus, when it is necessary to move the refrigerator, simply adjust the roller assembly to the unlocked state to move and adjust the position of the refrigerator. When it is necessary to position the refrigerator, adjust the roller assembly to the locked state accordingly to achieve the positioning effect of the refrigerator at the current position.

[0036] like Figure 2-4 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 the roller assembly 2 and roller holes 13 corresponding to the position of the roller assembly 3 inside. The roller holes 13 and roller assembly 3 are engaged and matched. The roller holes 12 provide an observation window and deformation space for the roller assembly 2, while the roller holes 13 are used to realize the fixed connection between the roller assembly 3 and the substrate 1.

[0037] like Figure 2 As shown, side edges 14 are fixedly extended downward on both sides of the base plate 1. The side edges cover the outer edge of the roller assembly 2 and the side edges partially cover the outer edge of the roller assembly 3. This provides mounting support for the roller assembly 2 and facilitates operation and adjustment of the roller assembly 3. A pivot hole 141 is provided inside the side edge 12 to facilitate the installation of the pivot 21 inside it.

[0038] like Figure 2As shown, the roller assembly 2 in this embodiment includes a rotating shaft 21 and a roller 22. The rotating shaft 21 is fixedly inserted 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 rotating shaft 21 on the outer periphery of the rotating shaft 21.

[0039] like Figure 2 and Figure 5-6 As shown, the roller assembly 3 in this embodiment includes an adjusting member 31. The top of the adjusting member 31 is fixedly engaged with the roller hole 13. An operating member 32 is threadedly connected to the outer side of the adjusting member 31. A column shaft 33 passes through the inside of the adjusting member 31. The roller 34 is movably disposed inside the adjusting member 31 and is movably sleeved on the outer periphery of the column shaft 33. A gap 35 is provided between the outer edge of the roller 34 and the inner cavity of the adjusting member 31 to facilitate the rotation of the roller 34 in the inner cavity of the adjusting member 31.

[0040] In this embodiment, the adjusting member 31 includes an upper small-diameter portion 311 and a lower large-diameter portion 312 formed as one piece. The small-diameter portion 311 is engaged with the roller hole 13 to achieve a fixed connection with the base plate 1. The outer wall of the large-diameter portion 312 is provided with an external thread that engages with the operating member 32. The operating member 32 is fixed with an internal thread portion 321. The inner wall of the internal thread portion 321 is provided with an internal thread that engages with the external thread on the outer wall of the large-diameter portion 312. Thus, the operating member 32 can move up and down on the outside of the adjusting member 31 through the thread engagement, thereby achieving the locking and unlocking of the refrigerator feet.

[0041] When the operating member 32 rotates on the outside of the adjusting member 31 through the threaded engagement until it is in the low position, the operating member 32 contacts the ground, thereby locking the roller assembly 3 at the bottom of the base plate 1, and the refrigerator feet cannot move at this time.

[0042] When the operating member 32 rotates on the outside of the adjusting member 31 through the threaded engagement until it reaches the high position, the operating member 32 disengages from the ground, thereby making the roller assembly 3 unlocked at the bottom of the base plate 1, at which time the refrigerator feet can move.

[0043] The specific working process of this embodiment is as follows:

[0044] When the refrigerator needs to be moved, the operating part 32 is rotated on the outside of the adjusting part 31 through the threaded engagement until it is in the low position. When the operating part 32 contacts the ground, the roller assembly 3 is locked at the bottom of the base plate 1. At this time, the roller assembly 2 is unable to move because the friction between the operating part 32 and the ground is large.

[0045] When the refrigerator needs to be positioned, the operating member 32 is rotated on the outside of the adjusting member 31 through the threaded engagement until it is in the high position. The operating member 32 is then disengaged from the ground, thereby unlocking the roller assembly 3 at the bottom of the base plate 1. At this time, the roller assembly 2 can move because the friction between the operating member 32 and the ground disappears.

[0046] As a further preferred option, in order to extend the service life of the operating component 32 and reduce assembly costs, the operating component 32 is preferably made of wear-resistant plastic material, and has textured surfaces on its outer side to facilitate user operation.

[0047] 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.
