Description

Technical Field

[0001] The utility model relates to the technical field of mesh cover design, in particular to a metal protective mesh cover with high structural performance. Background Art

[0002] Fans are common equipment in factories. In order to ensure the normal operation and safety of fans, fan protective covers are installed on the outside of the fans. The existing mesh covers on the market include a center circle, a support frame and a mesh body. The support frame is radially fixed to the center circle, and the other end of the support frame extends out of the center circle to serve as a support and installation device for the metal mesh cover.
