Description

Technical Field

[0001] The utility model relates to the technical field of radiation protection equipment, in particular to a radiation protection door curtain. Background Art

[0002] The patent name is: Radiation-proof automatic door curtain, and the publication number is: CN215804289U, a Chinese utility model patent. It uses a mounting frame, a rotating shaft, a driving motor, a guide groove, a metal mesh and a protective cover. One end of the metal mesh is fixedly connected to the rotating shaft and wound on the rotating shaft. The metal mesh can be retracted and extended by a motor drive.

[0003] The door curtain made of metal mesh is fixed on the rotating shaft by pressure strips and self-tapping screws. In the actual test process, if the fixing requirements are met, it is necessary to fix the door curtain at multiple points. When the door curtain needs to be replaced or repaired, multiple self-tapping screws need to be removed, which will increase the difficulty and complexity of maintenance. For this reason, we propose a radiation-proof door curtain. Utility Model Content
