Liftable folding dining table and working method thereof

Abstract

The invention relates to a liftable folding dining table and a working method thereof. The liftable folding dining table comprises table legs and a tabletop board. Each table leg comprises a lower table leg and an upper table leg slidably sleeving the upper end of the lower table leg in the vertical direction, wherein the lower table leg is in screw joint with a vertical lifting screw, and the upper table leg is provided with a power mechanism A for driving the lifting screw to rotate. The tabletop board comprises a fixed table board fixedly connected to the top of the upper table leg and folding table boards arranged on the two sides of the fixed table board. Each folding table board comprises a first-stage folding table board and a second-stage folding table board, wherein the first-stage folding table board is located between the fixed table board and the second-stage folding table board, the first-stage folding table board is hinged to the fixed table board through hinges, and folding telescopic lever mechanisms driven by power mechanisms B are arranged between the second-stage folding table board and the upper table legs. The liftable folding dining table is reasonable in structural design and convenient to operate, integrates folding and lifting and has the automatic telescopic function of an ordinary telescopic table; besides, folding and unfolding of the two folding table boards are realized, and thus the liftable folding dining table has a larger tabletop area.

Description

[0001] Technical field: [0002] The invention relates to a liftable folding dining table and a working method thereof. [0003] Background technique: [0004] With the improvement of modern living standards, people have a great demand for the function and taste of furniture. People's use of furniture is not limited to its practical functions, but puts forward more and higher requirements for furniture, such as richness of furniture functions, convenience of use, and aesthetics. People's needs for furniture use are mainly divided into the following aspects: richer and more integrated use functions, simpler and more automatic use methods, more beautiful and more humanized appearance design. [0005] At present, there are two main forms of folding dining tables: [0006] 1. Folding type, each table body part is independent of each other, and the table body is assembled manually mainly through hinges, suction cups, etc. as connectors. Although this folding method minimizes the ...

AI Technical Summary

Problems solved by technology

The screw type lifting mainly uses the relative movement of the screw and the slider to realize the lifting of the table body. It has a large bearing capacity and is widely used; the worm type lifting mainly uses the relative movement of two worm pairs to realize the lifting of the table body. Its bearing capacity is Among the three methods, the bearing capacity is the largest, but it is far greater than the ordinary force of the desktop in daily life. Secondly, the processing difficulty and cost of the worm and the worm pair are not suitable for use in real life; the lever type lifting is mainly realized by the cooperation of the lever and the hinge. Lifting, its structural design is simple and the cost is the lowest, but when the lever is used as the table leg, the tabletop is unstable, so it is not suitable for the lifting of the medium-sized dining table, only suitable for small desks on the bed

To sum up, the three lifting methods mainly rely on manpower as the driving force, so as to realize the lifting and unfolding of the table, and the operation is complicated
