Description

Technical Field

[0001] The utility model relates to the field of refrigerator design, in particular to a foot and a refrigerator having the foot. Background Art

[0002] When using household appliances, in order to ensure their normal operation, the bottom of the entire device must be in the same horizontal plane. However, since the ground in the actual use environment is often uneven, all or part of the feet of household appliances must have an adjustment function to adapt to the ground at different heights to ensure the normal use of household appliances on uneven ground.

[0003] Take the refrigerator as an example. If the refrigerator body is not level or the feet are suspended, it will cause unnecessary noise and vibration during operation. In order to solve this problem, the feet of the refrigerator need to be leveled. At present, the feet of the refrigerator are usually adjusted by rotating the support base to adjust the depth of the bolts screwed into the bottom plate of the refrigerator, thereby changing the height of the refrigerator. However, there are some problems with this adjustment method. Since the support base of the foot is usually in direct contact with the ground, it is often laborious to rotate it; especially when the rear foot (usually the foot on the side against the wall) needs to be adjusted, the adjustment process will be more difficult.

[0004] Therefore, in order to improve user experience and reduce problems during use, we need to explore some new foot design structures to meet the needs of more efficient and convenient adjustment. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] refer to Figure 8As shown, the utility model relates to a refrigerator, which includes a box body 400, and the bottom of the box body 400 is also fixed with feet to support the box body 400. It can be understood that in some embodiments of the utility model, the bottom of the box body 400 can be provided with a foot at each of the four corners; in other embodiments of the utility model, other numbers of feet can also be provided at the bottom of the box body 400.

[0029] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the footing involved in the utility model includes a support seat 100, a mounting seat 200 and a connecting rod adjustment assembly 300. Among them, the support seat 100 has a support guide rod 11 that slides with the mounting seat 200 in the vertical direction, and the connecting rod adjustment assembly 300 acts between the support guide rod 11 and the mounting seat 200 to adjust and lock the height position of the mounting seat 200 relative to the support seat 100.

[0030] exist Figure 8 In the specific application scenario of the refrigerator shown, the foot is connected and fixed to the bottom of the box body 400 through the mounting base 200, and supported on the ground by the support base 100. In this way, the horizontality of the refrigerator can be adjusted by adjusting the height position of the mounting base 200 relative to the support base 100.

[0031] The present invention provides a foot structure that is different from the related art. The height position of the mounting base 200 relative to the support base 100 can be adjusted through the connecting rod adjustment assembly 300. When used in household appliances such as refrigerators, users can easily raise or lower the foot, which can overcome the problem of difficulty in adjusting the height of the rotating support base in the related art, thereby ensuring that the household appliances can operate smoothly under various ground conditions.

[0032] In order to better understand the present invention, some specific implementation structures of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0033] Combination Figure 1-Figure 4 As shown, in this embodiment, the link adjustment assembly 300 includes a rotating link 31, a sliding link 32 and an adjusting member. Among them, one end of the rotating link 31 is rotatably connected to the support guide rod 11 through a first horizontal axis 301; the lower end of the sliding link 32 is rotatably connected to the other end of the rotating link 31 through a second horizontal axis 302, and the upper end 320 of the sliding link 32 is abutted against the mounting seat 200, wherein the extension direction of the second horizontal axis 302 is parallel to the extension direction of the first horizontal axis 301. The adjusting member acts between the support guide rod 11 and the sliding link 32 to change the distance between the two in the horizontal direction, and cooperates with the rotating link 31 to adjust the height of the upper end of the sliding link 32.

[0034] Figure 1-Figure 4 In the illustrated embodiment, based on the cooperation between the connecting rod adjustment assembly 300 and the supporting guide rod 11, the height of the upper end of the sliding link 32 can be adjusted by changing the distance between the supporting guide rod 11 and the sliding link 32 in the horizontal direction through the adjusting member, thereby realizing the adjustment of the height of the mounting seat 200 supported by the upper end of the sliding link 32.

[0035] To ensure smooth operation of the connecting rod adjustment assembly, in the specific implementation process, the support guide rod 11 is formed with a clearance groove (not marked in the figure) at the setting position of the first horizontal axis 301. One end of the rotating connecting rod 31 is fitted in the clearance groove and is rotatably connected to the support guide rod 11 through the first horizontal axis 301. During the rotation of the rotating connecting rod 31, the clearance groove ensures that the support guide rod 11 will not interfere with the rotation of the rotating connecting rod 31. Figure 4 As shown, in this specific embodiment, the clearance groove is formed through the supporting guide rod 11 in the horizontal direction perpendicular to the extending direction of the first horizontal axis 301 .

[0036] Correspondingly, a yielding structure may be provided at the position where the rotating link 31 and the sliding link 32 are rotatably connected to avoid interference between the two during rotation. Figure 4 In the illustrated embodiment, a clearance groove (not shown) may also be formed at the setting position of the second horizontal axis 302 of the rotating link 31 , and the lower end of the sliding link 32 extends into the clearance groove and is rotatably connected to the rotating link 31 through the second horizontal axis 302 .

[0037] In some more specific embodiments, Figure 4 , Figure 5 As shown, the adjustment member involved in this embodiment is a screw rod 33. More specifically, a strip hole 110 extending in the vertical direction is formed on the support guide rod 11, and the screw rod 33 passes through the strip hole 110 and is threadedly engaged with a threaded hole (not marked in the figure) on the sliding link 32, and the screw rod 33 has a nut 330 engaged with the side of the support guide rod 11 away from the sliding link 32.

[0038] In a specific application scenario, an adjustment portion that cooperates with a tool (such as a wrench) can be formed on the nut 330. The user can use the tool (such as a wrench) to act on the nut 330 to rotate the screw 33, thereby adjusting the distance between the support guide rod 11 and the sliding link 32, and thus changing the height of the upper end of the sliding link 32.

[0039] It can be understood that in other embodiments of the present invention, the adjusting member may not be limited to the screw 33 shown in the illustrated embodiment, but other structures that can adjust the horizontal distance between the support guide rod 11 and the sliding link 32 and thereby change the height of the upper end of the sliding link 32. The user can apply a force through the adjusting member to drive the support guide rod 11 and the sliding link 32 to move relatively closer or farther in the horizontal direction; the tool that provides the rotational force of the screw 33 is not limited to manual tools such as wrenches, but can also be components such as motors that can achieve automatic adjustment.

[0040] Combination Figure 3 , Figure 5 As shown, in this specific embodiment, the mounting seat 200 has a top wall 21 and a bottom wall 22 arranged opposite to each other, and the top wall 21 and the bottom wall 22 are respectively provided with an upper guide hole 210 and a lower guide hole 220 for the support guide rod 11 to pass through. The cooperation between the upper guide hole 210, the lower guide hole 220 and the support guide rod 11 can limit the relative movement between the mounting seat 200 and the support guide rod 11 in the vertical direction.

[0041] In order to reliably limit the relative movement between the mounting seat 200 and the support guide rod 11 in the vertical direction, the cross-sectional shape of the matching parts of the support guide rod 11 and the upper guide hole 210 and the lower guide hole 220 in the utility model are respectively consistent with the shapes of the corresponding guide holes, that is, the cross-sectional shape of the matching part of the support guide rod 11 and the upper guide hole 210 is consistent with the shape of the upper guide hole 210, and the cross-sectional shape of the matching part of the support guide rod 11 and the lower guide hole 220 is consistent with the shape of the lower guide hole 220. This can avoid shaking of the mounting seat 200 during the movement relative to the support guide rod 11.

[0042] As a preferred embodiment of the present invention, at least one of the upper guide hole 210 and the lower guide hole 220 is configured in a non-circular shape, so as to prevent the mounting seat 200 from rotating relative to the axis of the supporting guide rod 11 in the vertical direction. Figure 3 In the illustrated embodiment, the upper guide hole 210 is rectangular in shape, and the lower guide hole 220 is circular in shape; accordingly, the cross-sectional shape of the portion where the support guide rod 11 cooperates with the upper guide hole 210 is rectangular, and the cross-sectional shape of the portion where the support guide rod 11 cooperates with the lower guide hole 220 is circular. Based on the cooperation between the support guide rod 11 and the upper guide hole 210, the mounting seat 200 can be prevented from rotating relative to the axis of the support guide rod 11 in the vertical direction.

[0043] In addition, in the specific implementation process of the present utility model, combined with Figure 3 , Figure 5As shown, the bottom wall 22 extends upward from the edge of the guide hole 220 to form an annular wall (not marked in the figure), which can cooperate with the outer surface of the support guide rod 11 to ensure the reliability of the cooperation between the support guide rod 11 and the mounting seat 200.

[0044] In the present invention, based on the arrangement of the top wall 21 and the bottom wall 22, as Figure 5 As shown in , as a preferred embodiment, the connecting rod adjustment assembly 300 is located between the top wall 21 and the bottom wall 22, and the upper end 330 of the sliding connecting rod 32 abuts against the bottom of the top wall 21. In this way, when the height of the sliding connecting rod 32 is adjusted, the top wall 21 supported by the upper end 330 thereof will also change with the height adjustment of the sliding connecting rod 32, thereby achieving the height adjustment of the mounting seat 200.

[0045] In the process of the sliding link 32 approaching or moving away from the supporting guide rod 11 in the horizontal direction, the upper end 330 of the sliding link 32 is prevented from sliding and deviating relative to the top wall 21. Figure 2 and Figure 5 As shown in the figure, a slide groove 211 is provided at the bottom of the top wall 21 for the upper end 320 of the sliding link 32 to slide. At this time, when the sliding link 32 moves away from or approaches the supporting guide rod 11 in the horizontal direction, the upper end 320 of the sliding link 32 slides in the slide groove 211. In the specific implementation process, in order to make the sliding more smooth, the slide groove 211 can be coated with lubricating oil; in other embodiments not shown in the figure, an oil storage structure for storing a certain amount of lubricating oil can also be provided in conjunction with the slide groove 211.

[0046] In some specific embodiments of the present invention, the cross-sectional area of ​​the upper end 320 of the sliding link 32 is larger than the cross-sectional area of ​​the lower end thereof, so that the sliding link 32 can form a more stable support for the mounting seat 200. Figure 4 , Figure 5 As shown, the sliding link 32 involved in this specific embodiment is generally in a "T" shape.

[0047] In addition, reference Figure 1 As shown in the figure, in this specific embodiment, a fixing portion 24 is also provided on the bottom wall 22 of the mounting seat 200, and the design form of the fixing portion 24 is adapted to the object to be connected and fixed. During the assembly process of the specific refrigerator, the foot can be connected and fixed to the bottom of the box body 400 through the fixing portion 24.

[0048] In the present invention, in order to facilitate the user to adjust the adjustment member, the mounting seat 200 is provided with an adjustment window 230 for adjusting the adjustment member. Figure 1 , Figure 3As shown, in this specific embodiment, the mounting base 200 has a side wall 23 connecting the top wall 21 and the bottom wall 22, and the side wall 23 corresponds to the side where the nut 330 of the screw 33 is located. In order to facilitate the user to use a tool to rotate the screw 33, an adjustment window 230 is provided on the side wall 23. When the user needs to adjust the height of the foot, the tool can be passed through the adjustment window 230 and then cooperated with the nut 330 of the screw 33, thereby realizing the rotation of the screw 33. In this embodiment, in addition to serving as a channel for adjusting the screw 33, the adjustment window 230 can also serve as an identification structure indicating the position of the nut 330 of the adjustment screw 33. In the specific application scenario of the refrigerator, the side of the mounting base 200 with the adjustment window 230 is preferably facing the front side of the refrigerator (corresponding to the side where the refrigerator door is located).

[0049] In the illustrated embodiment, the mounting base 200 has side walls without adjustment windows 230 , which are mainly used to connect the top wall 21 and the bottom wall 22 to ensure a relatively reliable connection between the top wall 21 and the bottom wall 22 .

[0050] It can be understood that in other embodiments of the present invention, the side between the top wall 21 and the bottom wall 22 of the mounting base 200 where no side wall is set can also be directly used as an adjustment window for adjusting the adjustment member. At this time, the side where the nut 330 of the screw 33 is located corresponds to the side of the mounting base 200 where no side wall is set.

[0051] In a more preferred embodiment of the present invention, the support seat 100 further comprises a seat cushion 12 disposed on the lower side of the mounting seat 200, and the seat cushion 12 is fixed to the lower end of the support guide rod 11. In the specific application scenario of the refrigerator, its outer diameter is usually larger than the cross-sectional area of ​​the support guide rod 11, and the seat cushion 12 is used to directly contact the ground. The relatively large contact area can avoid the problem of excessive local pressure on the ground caused by the refrigerator. The seat cushion 12 can be fixedly connected to the lower end of the support guide rod 11 by means of threaded fit or interference fit.

[0052] In order to better understand the adjustment method of the foot involved in the utility model, the following Figure 6 , Figure 7 A more detailed description is given.

[0053] refer to Figure 6As shown, at this time, the foot is at the first adjustment height, and the distance between the top of the mounting base 200 and the bottom of the support base 100 is h1. When the user needs to raise the height of the foot, the user can pass one end of the tool (such as a wrench, not shown) used to rotate the screw rod 33 through the adjustment window 230 and then cooperate with the nut 330 of the screw rod 33; then, by tightening the screw 33, the sliding link 32 is moved closer to the support guide rod 11 in the horizontal direction; in this process, based on the connection relationship between the sliding link 32, the rotating link 31 and the support guide rod 11, the sliding link 32 will be raised to a certain height in the vertical direction, so that the foot is at Figure 7 The second height shown, reference Figure 7 As shown, at this time, the distance between the top of the mounting base 200 and the bottom of the supporting base 100 is h2, wherein h2 is greater than h1.

[0054] It can be understood that when the height of the base needs to be lowered, it can be achieved by operating in the above direction, that is, by tightening the screw 33 in the direction opposite to the above adjustment direction so that the sliding connecting rod 32 moves away from the supporting guide rod 11 in the horizontal direction, the height of the base can be lowered. The details are not repeated here.

[0055] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0056] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
