Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerator shelves, and more specifically, to a refrigerator shelf with adjustable space. Background Art
[0002] Refrigerator shelves are usually used to organize and store food and drinks inside the refrigerator. They can help you use the space inside the refrigerator more efficiently and keep the food neat and orderly. Pull-out shelves are usually used in refrigerators nowadays.
[0003] After searching, the Chinese patent with publication number CN214665531U discloses a refrigerator shelf. The storage space of the existing refrigerator is divided into different functional areas by shelves, wine racks, egg racks and other components, and they are independent of each other. However, this independent separation of functional areas makes it impossible to fully utilize the effective space of the refrigerator. For example, even if there are no wine bottles on the wine rack of the refrigerator, the space will still be separated and cannot be used and is wasted. The general shelves are prone to cracking or even breaking when the pressure is too large. When placing items, it is inevitable that bumps and vibrations will occur, and the items are prone to slipping and falling. The shelf can bear heavier items. The shelf has anti-slip embossing to prevent items from falling. The main material of the shelf is tempered wired glass to prevent glass fragments from falling into the food when cracked or even broken. The limit switch and rubber improve the stability, and there is a special place to store beverages for rolling.
[0004] During the use of the refrigerator shelf, the number of refrigerator shelves is small, and the space of the shelves inside the refrigerator is inconvenient to adjust at will, and it is inconvenient to adjust the shelf space according to the height of specific stored items. At the same time, various items or foods are often placed on the shelves. During each adjustment process, the food needs to be moved down for easy adjustment, which is time-consuming and laborious to use. Utility Model Content
