Gene detection sample constant-temperature storage device

The invention relates to the technical field of gene detection, in particular to a gene detection sample constant-temperature storage device, which is characterized in that a plurality of rotating discs are arranged in a storage tanks respectively, the annular walls of the rotating discs movably abut against the inner annular wall of the storage tank, a plurality of first door bodies are hinged to an opening in the front side of the annular wall of the storage tank, and are in one-to-one correspondence with the rotating discs, a first rotating shaft is fixed in the multiple rotating discs in a penetrating mode, and the bottom end of the first rotating shaft is rotationally connected to the bottom of the storage tank through a bearing, so that containers containing gene detection samples can be kept at the same temperature and dry, uneven temperature is avoided, and when the containers containing the gene detection samples are taken, local temperature rise caused by cold air diffusion is avoided so as to preve
