Rotary table with liftable rotary disc
Technical Field
The invention relates to the technical field of dining tables with turntables, in particular to a turntable liftable and rotatable dining table.
Background
The dining table that has the carousel of current use is mostly adding a carousel on ordinary circular dining table, and such dining table carousel manual rotation, safe and reliable, though the cost is lower, but has many drawbacks: the first rotating disc is higher than the table top of the dining table, and once the dish basin is turned upside down, the soup can directly flow to the diner; when the second turntable rotates, articles such as bowls or beverage bottles beside the second turntable are easy to be knocked over; thirdly, the user needs to extend the hand into the dining table to rotate the turntable, so that the user is inconvenient and is easy to turn over articles such as bowls or beverage bottles; the fourth rotary table is easy to rotate and cannot rotate due to the factors of uneven stress and the like.
In recent years, electric dining tables have been raised at home and abroad, the turntables of the electric rotary dining tables are adopted, manpower is not needed, and the electric dining tables look very tall and big, but have many defects: the price ratio is higher, and the power consumption has the electric leakage potential safety hazard for 240 volts, and control switch only has an inconvenient use, and the rotation that does not stop is also not favorable to the dish of pressing from both sides, and is heavier to dismantle transport inconvenient, etc..
Disclosure of Invention
