Embodiment 1

[0038] The refrigerator shelf of the present invention comprises: a movable shelf 1, a shelf 12 placed above the movable shelf 1, a base 2 positioned below the movable shelf 1, a lead screw 4, such as Figure 4The first pole 31 and the second pole 32 shown, wherein, the lower bottom surface of the movable shelf 1 is provided with a first chute; The position from the first end of the polished rod 43 to the first end of the polished rod 43 is provided with a first thread 41, the first thread 41 is a left-handed double-thread structure, and a first nut 71 with a right-hand double-thread structure is sleeved on it, along the A second thread 42 is provided at the position from the second end of the lead screw 4 to the second end of the polished rod 43. The second thread 42 is a right-handed double-thread structure, and a second nut with a right-hand double-thread structure is sleeved on it. 72. On the outer wall of the first nut 71 and on the outer wall of the second nut 72, first ...

Embodiment 2

[0042] Such as Figure 5 As shown, the structure of the refrigerator shelf of this embodiment is similar to that of Embodiment 1, the only difference being that the first pole 31 and the second pole 32 do not intersect each other.

[0043] The refrigerator shelf of the present invention not only has the advantages of the structure in the first embodiment, but also has no cooperation between the first pole 31 and the second pole 32, so the friction loss between each other is reduced, and the movable shelf can be adjusted 1 height is more labor-saving.

Embodiment 3

[0045] Such as Figure 6 As shown, the difference between the structure of the refrigerator shelf of this embodiment and the first embodiment is that the middle part of the base 2 close to the first end is provided with a second sliding groove 21 along the horizontal direction, and the middle part near the second end of the base 2 is provided along the horizontal direction. The third chute 22 is provided in the direction, and the second chute 21 and the third chute 22 are arranged symmetrically with respect to the central position of the base 2; the middle part of the first pole 31 and the middle part of the second pole 32 Next, the lower end of the first pole 31 is slidably pivoted to the second slide slot 21 , and the lower end of the second strut 32 is slidably pivoted to the third slide slot 22 .

[0046] When the present invention is in use, the shelf 12 is placed on the movable shelf 1. When the dial 61 is moved, the synchronous belt 6 will be driven with the movement of...

Abstract

The invention provides a refrigerator shelf and a refrigerator comprising the same. The refrigerator shelf comprises a movable shelf and a lifting structure which is movably arranged below the movable shelf, wherein the lifting structure comprises a first horizontal connecting piece, a second horizontal connecting piece and a supporting rod, and two ends of the supporting rod are pivoted with the first horizontal connecting piece and the second horizontal connecting piece respectively; at least one of the first horizontal connecting piece and the second horizontal comprises a lead screw and a nut, and the lead screw is sleeved with the nut; threads matched with the nut are formed in the lead screw; and the lead screw is pivoted with the supporting rod through the nut. According to the refrigerator shelf and the refrigerator comprising the same, the distance between the movable shelf and a space below the movable shelf can be freely adjusted, the adjusting range is wide, the position can be adjusted at random, effective self-lock can be achieved, and the lead screw is sleeved with the nut, so that a tripping phenomenon cannot happen to the lead screw. The refrigerator shelf and the refrigerator comprising the same can be operated simply, and are safe and reliable.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a refrigerator shelf and a refrigerator including the shelf. Background technique [0002] The refrigerator shelves on the market are roughly divided into the following three types: [0003] Non-adjustable type, when the space under the shelf is not large enough, you need to take out the things on the shelf and then take the shelf down and put it on the upper bracket, and then put the things on it, this structure brings convenience to the user There was a lot of inconvenience and trouble. [0004] Adjustable type, this kind of form divides the shelf into two parts, the front part is adjusted and placed under the second half of the shelf, and the shelf is folded and reliable on the back wall of the refrigerator. This method can adjust a certain space under the shelf , but the adjustment space is limited and cannot be lifted. [0005] Liftable, liftable shelves, such as the patent C...
