Abstract
A system for fastening a cover to a body of an explosion-proof enclosure using a plurality of fastening devices. Each fastening device can include a first load distributing member disposed on a body flange of a body of the explosion-proof enclosure. Each fastening device can also include a second load distributing member disposed on a cover flange of a cover of the explosion-proof enclosure. Each fastening device can further include a fastener positioned atop the first load distributing member, where the fastener traverses the first load distributing member, the cover flange, and the body flange. Each fastening device can also include a fastener receiver positioned under the second load distributing member and mechanically coupled to the fastener.
Claims20
A system for fastening a cover to a body of an enclosure, comprising:
- a flange comprising at least one slotted aperture disposed in a distal end of the flange;
- an opposing flange comprising at least one anchor receiver, wherein the opposing flange abuts against the flange;
- and
- at least one fastening device, wherein each fastening device of the at least one fastening device comprises:
- an anchor hingedly disposed in the at least one anchor receiver of the opposing flange;
- a stem comprising a first end and a second end, wherein the first end is coupled to the anchor, and wherein the second end is movably disposed within the at least one slotted aperture of the flange;
- and
- a head movably coupled to the second end of the stem, wherein the head is coupled to an outer surface of the flange adjacent to the at least one slotted aperture when the at least one fastening device couples the flange and the opposing flange.
