Abstract

The invention discloses a movable terrace classroom, and belongs to the field of teaching equipment. The terrace classroom comprises multiple layers of telescopic steps, a plurality of foldable tables and a plurality of chairs, wherein the multiple layers of steps comprise a top layer step, a bottom layer step and at least one middle layer step between the top layer step and the bottom layer step; guide rail sliding chutes are formed in adjacent steps; ball screw nuts are arranged at the bottoms of the top layer step and the middle layer step; lead screws are fixed on upper steps in adjacent steps, and nuts are fixed on lower steps; intervals are formed between adjacent steps; table legs of the tables are hinged to the steps; chair legs of the chairs are hinged to the steps; the tables and the chairs are uniformly arranged on each layer of step; the tables and the chairs can be accommodated in the intervals between adjacent contracted steps after being folded. According to the movable terrace classroom, the steps expand by extending out of the tables and the chairs on a flat ground to form the terrace classroom. When the terrace classroom is taken as a flat ground classroom, the tables and the chairs are folded, the steps retract, and the tables and the chairs can be used detachably.
