inserting the temperature measuring device with the measuring rod (10) and the supporting rod (12) in a folded state into the gas cylinder (16), screwing the cylinder opening plug (7), and screwing the cylinder opening plug (7) into the cylinder opening of the gas cylinder (16) so that the base (13) is abutted against the inner bottom of the gas cylinder (16); the bottle mouth plug (7) is continuously screwed in, the spring (14) of the spring seat (15) is compressed by the bottom plate (17) of the threading pipe (9), and the temperature measuring rods (10) in the bottommost group are opened under the supporting force of the supporting rods (12); under the action of the transmission rod (11), the other temperature measuring rods (10) are also opened; the temperature sensor patch at the tail end of the measuring rod (10) is in contact with the inner wall surface of the gas cylinder (16) so as to measure the temperature conveniently; the cap (1) is screwed down, the sealing element (2) is pressed, gas is filled into the gas filling port (722) on the bottle mouth plug (7), and the temperature measurement is started.
8. Use according to claim 7 for measuring the temperature inside a high-pressure gas cylinder, characterized in that:
after the temperature is measured, gas in the gas cylinder (16) is completely discharged through the charging port (722), the cylinder opening plug (7) is screwed out, the base (13) and the threading pipe (9) are relatively displaced under the action of elastic force of the spring (14) of the spring seat (15), and the measuring rod (10) and the supporting rod (12) are folded; the entire temperature measuring device is then pulled out of the gas cylinder (16).
