Lifting table-on-table

Abstract

A lifting table-on-table comprises an upper panel, a lower panel, a bracket component and a base. A plurality of slide rails are symmetrically arranged at the lower side of the upper panel; the base comprises first bottom rods and second bottom rods arranged in parallel; a plurality of slide rails are symmetrically arranged at the inner sides of the first bottom rods; the bracket component comprises two pairs of first brackets and second brackets in an X shape; transmission shafts provided with slide blocks on both ends are installed between the top ends of the first brackets and the second brackets; the slide blocks are installed at the bottom ends of the first brackets and the second brackets through rotating shafts; the bracket component is movably connected between the upper panel and the base through the matching of the slide blocks and the slide rails; and a lifting mechanism is installed between the second brackets and the transmission shaft below the upper panel. Compared with the prior art, in the table-on-table, by arranging the lifting mechanism matched with the handle on the upper panel, the height of the table-on-table can be adjusted quickly and smoothly. By arranging the X-shaped bracket component, the strengthening arms and the supporting rod, the stability of the bracket component is enhanced and the height of the entire bracket component is collaboratively adjusted to simplify the structure of the table-on-table.
