Description

A folding table and chair

technical field

The utility model relates to a table and chair, in particular to a foldable table and chair.

Background technique

At present, most of the desks and chairs in the market are simple back chairs, swivel back chairs or backless chairs, but the current desks and chairs are all fixed. This structure takes up a lot of space and is not easy to carry. There is a table and chair device with folding function, and its structure is mainly folding, sliding rod, hinge, cross support, etc.; Chinese patent application number 200820020788.2 introduces an integrated portable table and chair, which is hinged with the chair through folding branches. This kind of folding tables and chairs occupies a large amount of space, has an old-fashioned structure, and the hinged tables and chairs are also damaged. Although the height of the desktop is adjustable, the structure is rigid, too many hinges, the style is complicated, and the comfort is also poor.

Utility model content

The utility model aims at the deficiencies of the above problems, and provides a folding table and chair, which is convenient to open or fold the table and chair. After opening, the table top is circular, and the seat surface is fan-shaped, which can be used by four people, and the volume becomes smaller when folded. The table and chair device saves space and is easy to carry. The table and chair device is simple and is suitable for occasions such as home and field trips.

In order to solve the above problems, the utility model provides a technical solution as follows: a folding table and chair, which is composed of a table board, a support shaft and four chairs, and the table board with a ring is socketed on the support provided with a table board tray. On the shaft, the lower end of the support shaft is provided with a base, and the support shaft between the table tray and the base is provided with a telescopic support, and the chair is connected with the connecting plate on the telescopic support through a telescopic rod.

The supporting shaft is a stepped shaft structure, which is composed of a top cover, a table tray, an upper chuck, a lower chuck and a base.

The table top is formed into a circle by four fan-shaped board surfaces, rings are arranged on the inner circular arcs of the four board surfaces, and grooves and convex clamping blocks are respectively provided on the two straight edges of the board surface.

A chair leg slot is arranged on the back of the chair surface, and the chair leg of the chair is hinged to one end of the chair leg slot.

Beneficial effects of the utility model:

In the utility model, the grooves on the table board and the locking of the clamping blocks maintain the horizontal structure of the table top when in use, avoiding the use of metal devices in the previous technology, which not only ensures the beauty of the table top but also reduces the weight of the table and chairs ,reduce manufacturing cost.

The folding table and chair device in the utility model is fan-shaped after being folded, and is designed by combining geometric curves and straight lines. the
