Optical module high and low temperature rapid testing device

The invention relates to an optical module high and low temperature rapid testing device, and belongs to the technical field of optical communication, the optical module high and low temperature rapid testing device comprises a U-shaped transmission frame and a U-shaped conveyor belt, the U-shaped conveyor belt is installed on the U-shaped transmission frame, a plurality of clamping seats are fixedly connected to the U-shaped conveyor belt, and optical modules are clamped in the clamping seats. The U-shaped transmission frame is fixedly connected with a space temperature testing assembly, gas is injected into the inner-layer bag bodies of the heating testing bin and the refrigeration testing bin through different gas conveying pipes, so that the inner-layer bag bodies expand, under the condition that the inner-layer bag bodies expand, the outer walls at the positions of expansion openings are driven to expand, and therefore the expansion openings are closed; the interiors of the heating test bin and the refri
