  The object of the present invention is to overcome the above-mentioned drawbacks existing in the prior art, and to provide a table plate and a portable folding table with a rational structure design, a large adjustment range of the table plate area, and a high unity of the table plate. There is to do.

  The technical solution that the present invention adopts to solve the above problems is as follows.

  A portable folding table comprising a table plate and a support leg frame for providing the table plate, the table plate comprising several panels and a connecting piece for connecting adjacent panels, Both the front and rear ends of the panel are provided with slide grooves, the panels of the table plate are provided one by one from left to right, and both ends of the connecting piece connect two adjacent panels, One end of the connecting piece is mounted in one slide groove of the panel so that the connecting piece slides with respect to the slide groove of one panel and can be rotated around one end of the connecting piece, The other end of the connecting piece is hinged to the end of the other panel so that the connecting piece can be rotated around the other end of the connecting piece, or the other end of the connecting piece is other By being mounted in the slide groove at the end of one panel, the connecting piece can slide with respect to the slide groove of the other one panel and can be rotated around the other end of the connecting piece. When the distance between the panels is small, the length of the table plate is correspondingly short, so the area of the table plate is small, and after the panels on both sides of the table plate are moved, the connecting piece slides against the slide groove. Portable folding, characterized in that the distance between the panels increases, the area of the table plate increases accordingly, and a cover plate is fixed on the panel to cover the gap between adjacent panels It is a table. As a result, when the distance between the panels increases, the cover plate can also cover the gap between adjacent panel bodies all the time, so there is not always a gap in the entire table surface in the process of changing the area of the table surface. .
