The invention discloses a counterweight mechanism. The counterweight mechanism comprises a counterweight assembly, a switching assembly, a mounting assembly and a hoisting assembly, according to the counterweight mechanism, the structure that a rotating shaft and a locking screw rod are used in cooperation is adopted, two-dimensional adjustment of the included angle and the distance between the door body and the balance weight mechanism is achieved, the gradienter is arranged, and the counterweight precision can be accurately controlled. The invention further discloses a zero-gravity expansion experiment device which comprises the counterweight mechanism, a hanging mechanism, a sliding rail mechanism and a frame body mechanism. The sliding rail mechanism comprises at least two longitudinal sliding rail assemblies parallel to each other and a transverse sliding rail assembly, the transverse sliding rail assembly is perpendicular to the two longitudinal sliding rail assemblies, and the upper portion of the sliding rail mechanism is fixedly installed on the frame body mechanism. The invention provides a two-dimensional guiding, multi-stage adjustable, large-span, high-precision and zero-gravity expansion experiment device according to the unfolding motion track requirement of a large door body mechanism, and can realize hanging and unloading at any position in an unfolding range of a large door body.
