Lifting device for shelves as well as shelf component and refrigerator

Abstract

The invention provides a lifting device for shelves as well as a shelf component and a refrigerator. The lifting device for the shelves comprises first rod bodies, second rod bodies, third rod bodies and sliding locking members, wherein the first rod bodies and the second rod bodies are rotabablely connected; the first rod bodies are provided with first transfer parts; the second rod bodies are provided with second transfer parts; at least one of the first transfer parts and the second transfer parts is used for being rotatablely connected with the shelves; the third rod bodies are rotatablely connected with the first rod bodies; the third rod bodies are provided with the sliding locking members which can rotate relative to the third rod bodies; the sliding locking members are arranged on the second rod bodies in a cooperation manner; and further, the sliding locking members can slide along the second rod bodies or be tightly locked with the second rod bodies. The lifting device for the shelves, which is provided by the invention, can be unfolded to support the shelves or folded to be convenient to store; moreover, the heights of the positions of the shelves can be regulated through regulating the sliding locking members; and the lifting device is simple in composition structure, and has the advantage that a spatial volume is small in both unfolding and folding states.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a lifting device for a shelf, a shelf assembly and a refrigerator. Background technique [0002] The glass shelves in the existing refrigerators are generally placed in three or four pieces, which need to be placed many times during on-site assembly, which is inconvenient to assemble, and multiple structures need to be installed on the tank to place the glass shelves; For the purpose of adjusting the position of the shelf, in the prior art, the placement structure is generally improved on the side wall of the refrigerator. However, such a structure has the problem of a large size after being folded, resulting in a large amount of space occupied by the structure. Of course, some The product uses the deformation principle of parallelogram to realize the adjustment of the glass shelf, but the adjustment in this scheme will make the glass shelf move back and forth, and the extra space ca...

[0002] The glass shelves in the existing refrigerators are generally placed in three or four pieces, which need to be placed many times during on-site assembly, which is inconvenient to assemble, and multiple structures need to be installed on the tank to place the glass shelves; For the purpose of adjusting the position of the shelf, in the prior art, the placement structure is generally improved on the side wall of the refrigerator. However, such a structure has the problem of a large size after being folded, resulting in a large amount of space occupied by the structure. Of course, some The product uses the deformation principle of parallelogram to realize the adjustment of the glass shelf, but the adjustment in this scheme will make the glass shelf move back and forth, and the extra space cannot be used, resulting in a waste of space, which is also not conducive to the optimization of the product structure
