Abstract:
1. A system for fastening a cover to a body of an explosion-proof enclosure using a plurality of fastening devices, wherein each fastening device of the plurality of fastening devices comprises: a first load distributing member disposed on a first flange of the explosion-proof enclosure; a second load distributing member disposed on a second flange of the explosion-proof enclosure, wherein the first flange abuts the second flange when the cover of the explosion-proof enclosure is coupled to the body of the explosion-proof enclosure; a securing member comprising a top end disposed on the first load distributing member and a bottom end disposed on the second load distributing member, and a cam rotatably coupled to the top end of the securing member and positioned atop the first load distributing member, wherein the cam has a closed position and an open position, wherein the cam, when in the closed position, pushes the top end of the securing member with a first force against a top surface of the first load distributing member and pulls the bottom end of the securing member with a second force against a bottom surface of the second load distributing member, wherein the first load distributing member distributes the first force along its length to result in a first distributed force, wherein the second load distributing member distributes the second force along its length to result in a second distributed force, and wherein the first distributed force is applied by the first load distributing member to the first flange, wherein the second distributed force is applied by the second load distributing member to the second flange, and wherein the first distributed force and the second distributed force are used to fasten the cover to the body of the explosion-proof enclosure and to provide a flame path between the first flange and the second flange of the explosion-proof enclosure.
