Positioning structure and oxygen control device

The utility model relates to the technical field of oxygen control devices, in particular to a positioning structure and an oxygen control device. The positioning structure comprises a fixing plate, an oxygen control box body, a positioning hole, a limiting block, a limiting hole, a positioning block, a positioning plate, a fixing hole, a positioning shell, an anti-falling plate, a guide rod, a spring, a traction rope and a positioning rod. The oxygen control box has the beneficial effects that the positioning plate is fixed on the surface of a wall through the fixing hole, the traction rope is pulled to drive the positioning rod to move upwards, and then the fixing plate is hung on the positioning block, so that the end part of the positioning block is inserted into the positioning hole to pre-position the oxygen control box body; then the traction rope is loosened, so that the positioning rod moves downwards through elastic jacking of the spring and is inserted into the limiting hole, positioning installati
