Abstract

The invention discloses a table and chair for office, teaching, medical care and construction sites. The table and chair comprises a bottom plate (100), a first guide rail (200), a chair part (300) and an expansion and contraction part (400), a first motor (401) drives a screw rod (416) to enable nuts (402) to move in the axis direction of the screw rod (416), the nuts (402) enable an expansion plate (408) to move along the first guide rail (200) through a first connecting rod (406), the expansion plate (408) on the upper side is used for fixing a table plate (415), and the expansion plate (408) on the lower side is used for being in contact with a rack; and the nuts (402) drive two third connecting rods (413) through second connecting rods (411) to pull chair legs (303) to be folded and expanded. Under the driving of the second connecting rods (411) and the third connecting rods (413), the chair legs (303) can be expanded, so that people can sit on the chair conveniently; and when the table and chair is retracted, the chair legs can reduce the occupied space. In addition, the height of the table plate (415) can be adjusted by adjusting the height of the upper expansion plate (408) at will.

Description

technical field [0001] The invention relates to a tool for office, teaching, medical care and construction sites, in particular to a table and chair for office, teaching, medical care and construction sites. Background technique [0002] In daily office, teaching, medical care, and construction sites, tables and chairs are necessary tools.
