A device for testing the airtightness and internal gas flow of a cryogenic insulation module includes an inlet / liquid inlet module, an outlet / liquid outlet module, and an insulation module. The inlet / liquid inlet module includes an inner space liquid nitrogen inlet valve, an outer space liquid nitrogen inlet valve, a low-pressure control module, an inner space high-pressure control module, an outer space high-pressure control module, a buffer tank, a pressure reducing valve, and a filter, all connected via pipes. The outlet / liquid outlet module includes a liquid nitrogen / nitrogen exhaust valve, an inner space exhaust valve, and an outer space exhaust valve, all connected via pipes. The outlet of the inlet / liquid inlet module is connected to the inlet of the insulation module, and the inlet of the outlet / liquid outlet module is connected to the outlet of the insulation module. This invention enables the airtightness testing and adaptability study of insulation modules under cryogenic and ambient temperature conditions, as well as the testing and research of internal gas flow performance.

The invention relates to the technical field of rehabilitation training, and discloses a rehabilitation training robot with joint torque feedback, which comprises a shell, a cover plate is fixedly mounted on the left side of the top of the shell, a seat assembly extending to the top of the cover plate is arranged on the inner side of the shell, and two outer boxes are fixedly mounted on the right side of the inner wall of the shell. A supporting seat is fixedly installed at the bottom of the shell, a training mechanism extending to the outer sides of the outer boxes is arranged between the inner sides of the two outer boxes, an adjusting mechanism connected with the training mechanism and extending to the right side of the shell is arranged between the two outer boxes, and a fixing mechanism is arranged at the top of the training mechanism; according to the rehabilitation training robot with the joint torque feedback function, the training mechanism and the adjusting mechanism are arranged, the supporting plate slides along the guide rail, the purpose of adjusting the training intensity is achieved, and the purpose of replacing different models is achieved by arranging the fixing mechanism.
