Fastening devices for explosion-proof enclosures

摘要

A fastening device for fastening a cover to a body of an explosion-proof enclosure can include a bracket having a back side mechanically coupled to a bottom side at a first angle and to a top side at a second angle, where the top side includes an engagement portion, where the first angle is substantially parallel to an under side of the body flange, and where the second angle is substantially parallel to a top side of the cover flange. The fastening device can also include a cam fixedly coupled to an outer surface of the cover flange and hingedly coupled to the engagement portion. The fastening device can further include a lever fixedly coupled to the cam and having a closed position and an open position.
