Anti-corrosion thermometer protection sleeve

The utility model discloses an anti-corrosion thermometer protective sleeve, which relates to the technical field of temperature measuring element sleeves and comprises a sleeve body and a connecting flange coaxially fixed on the upper portion of the sleeve body. The part, located below the connecting flange, of the sleeve body is a conical section with the diameter gradually reduced, and an anti-corrosion layer is laid on the surface of the conical section. A blind hole used for installing a thermometer is coaxially formed in the sleeve body, the blind hole extends to the bottom of the conical section, and the size of the blind hole is matched with the size of the thermometer; the large end of the conical section is connected with the connecting flange, so that the rigidity of the sleeve body is higher, the strength of the connecting position of the sleeve body and the connecting flange is higher, the impact resistance and the vibration resistance are higher, the anti-corrosion layer laid on the surface of t
