Description

Extensible conference table

Technical Field

The invention belongs to the technical field of office supplies, and particularly relates to an extensible conference table.

Background

The table is one of the well-known indispensable tools in daily household life, workplaces and entertainment places. If the desk is applied to office places, the desk can be an office desk or a conference desk; particularly, the conference table is used as an office appliance with a relatively fixed placement, the size of the table top of the conference table is generally fixed, and the table with a proper size is generally selected according to the number of conference participants or the size of a field during use. When the use place is relatively compact, people often only can select small-sized conference tables, but when the number of people is large, the conference tables are obviously not suitable. In order to provide better flexibility to the conference table during use, a stretchable and expandable conference table is also available in the market, and the structure of the stretchable and expandable conference table is that movable plates are additionally arranged at two ends or four sides of a table top, and the size of the table top is adjusted by unfolding or folding the movable plates. However, in practical use, the movable plates are arranged at the edge of the table, which easily affects the movement of the legs of the user, and the movable plates are positioned at the edge of the table during folding, which also affects the beauty of the conference table. Or the extensible auxiliary table plate is arranged in or below the main table surface, when the using area of the conference table needs to be enlarged, the auxiliary table plate only needs to be extended out of or below the main table surface, and the conference table adopting the technical scheme has the problems of inconsistent table surface height (uneven table surface) or inconsistent table surface width when in use, so that the convenience and the attractiveness of the table are influenced; a space saving conference table as disclosed in utility model application No. 201621464618.4 and a home retractable table as disclosed in invention patent application No. 201810525630.0.
