A parabolic cylinder deployable mechanism composed of deployable units is formed by combining a plurality of deployable units; each deployable unit comprises a first isosceles trapezoid piece, a second isosceles trapezoid piece, a first right trapezoid piece, a second right trapezoid piece, a third isosceles trapezoid piece, a fourth isosceles trapezoid piece, a first rectangular piece, a second rectangular piece, a first hinge, a second hinge, a third hinge and a fourth hinge; the two deployable units form the one-layer parabolic cylinder deployable mechanism in a manner of sharing a component, and the sharing component comprises the first isosceles trapezoid piece and the second isosceles trapezoid piece; the plurality of parabolic cylinder deployable mechanisms with the layer number of 1 are sequentially connected through a fifth hinge to obtain the parabolic cylinder deployable mechanism; and the parabolic cylinder deployable mechanism has the advantages of single-degree-of-freedom movement, large folding and unfolding ratio, good mechanism rigidity, stable unfolding and folding processes and good practicability.
