Description

Rotatable bowl support

Technical Field

The utility model relates to a tableware dining table, in particular to a rotatable bowl support.

Background

Rotatable dining tables in the current market are very heavy in weight and are not easy to carry and move; the volume is large, the occupied space is large, and a special space needs to be found for placement; the price is expensive, and the price is several times higher than that of the common dining table. For general families, the practicability is poor. Most of the rotary dining tables appear in public places such as hotels, clubs, large gear and the like, and a few abundant urban families are also provided with the rotary dining tables. This expensive furniture is not affordable in rural areas. In the rural dining habits, the staple food is preferred to be placed in the middle of the table, and other dishes are placed along the main menu in sequence. When more dishes are available, guests sitting on the east can not clamp the dishes on the west, and the guests do not like to clamp the dishes in the space. Especially when people put wine mats in rural areas, the phenomenon of inscription and insanitation often occurs. For example, when a new dish is not placed in a place after the dishes are fully stacked in the pot, a person can directly place another dish on the ground. When the vegetables are clamped at intervals, the meat lump which is not clamped falls down just in the soup pot, and the soup is splashed everywhere.
