The invention comprises a support plate; a side of the support plate is fixed with a limit guide rail; one side of the limit guide rail is provided with a lifting frame for installing a refrigerator shelf; the lift frame slides along the vertical direction of the support plate; There is a rectangular plate; one surface of the rectangular plate is provided with a waist-shaped hole; the surface of the waist-shaped hole is provided with teeth side by side along the length direction; a transmission gear meshing with the teeth is built in the waist-shaped hole; A through hole is provided; a positioning rod is interspersed in the through hole; one end of the positioning rod is fixed on the rectangular plate; the other end of the positioning rod is fixed with a boss; The invention drives the lifting frame to move up and down through the rectangular plate through the transmission gear, so as to realize the purpose of lifting the shelf of the refrigerator, and has the advantages of simple and reasonable structural design, convenient use and the like.
Description
technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a circulating lifting device for a refrigerator shelf. Background technique [0002] At present, the height of the refrigerator shelf is often fixed, or only adjusted in a limited number of positions, and the height is fixed, which is not conducive to the random adjustment of space. Adjusting in a limited number of positions often requires removing the food on the shelf to make adjustments, which is troublesome and time-consuming. The height adjustment of the refrigerator shelf is inconvenient, resulting in a low utilization rate of the refrigerator space, which cannot meet the needs of the people. This situation needs to be urgently changed. [0003] For the problem of adjusting the position of the refrigerator shelf, relevant technical personnel have given corresponding solutions. For example, the invention patent application with the patent publication numb...
