A heat preservation room for a mining transportable-type rescue-capsule constant-temperature testing apparatus provided by the utility model belongs to the technology field of integration protection performance tests of the mining transportable-type rescue capsule. The technical problems to be solved in the utility model are providing the heat preservation room for the mining transportable-type rescue-capsule constant-temperature testing apparatus and the heat preservation room is simple in structure, reliable in seal and low in cost. The adopted technology scheme is that the heat preservation room for the mining transportable-type rescue-capsule constant-temperature testing apparatus comprises a room body and two guide rails and two lighting devices; a double door is opened on a side surface of the room body. The structure of the room body is that a heat preservation layer is paved outside of a cuboid steel structure rack body, a shackle is mounted on the top of the room body, guide rails are disposed on a base plate in the room body and the lighting device is arranged on the top in the room body. The heat preservation room is used for the mining transportable-type rescue-capsule constant-temperature test.
