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, and a second load distributing member disposed on a cover flange of a cover of the explosion-proof enclosure. A fastening device can also include a securing member having a top end disposed on the first load distributing member and a bottom end disposed on the second load distributing member. A fastening device can further include a cam rotatably coupled to and positioned atop the first load distributing member.
Claims20
An electrical enclosure, comprising:
- a first enclosure portion comprising a flange;
- a second enclosure portion comprising an opposing flange;
- and
- a plurality of fastening devices, wherein each fastening device of the plurality of fastening devices comprises:
- a bracket comprising a top side, a bottom side, and a back side, wherein the top side is movably coupled to a first outside portion of the flange of the first enclosure portion of the electrical enclosure, and wherein the bottom side is movably coupled to a second outside portion of the opposing flange of the second enclosure portion of the electrical enclosure, wherein the top side, the bottom side, and the back side each have an inner surface and an outer surface;
- a fastener receiver positioned between the flange and the opposing flange and coupled to the opposing flange, wherein the fastener receiver is positioned adjacent to the inner surfaces of the bracket;
- a first fastener positioned on a third outside portion of the back side of the bracket and hingedly coupled to the fastener receiver, wherein the first fastener traverses a first aperture in the bracket;
- a securing device that movably abuts against the back side of the bracket;
- and
- a cam mounted on the first enclosure portion and hingedly coupled to the securing device, wherein rotation of the cam moves the securing device relative to the back side of the bracket,
- wherein the bracket, through the first fastener and the fastener receiver, remains coupled to the second enclosure portion when the securing device does not abut against the back side of the bracket.
A system for fastening a cover to a body of an electrical enclosure using a plurality of fastening devices, wherein each fastening device of the plurality of fastening devices comprises:
- a bracket comprising a top side, a bottom side, and a back side, wherein the top side is configured to be movably coupled to a first outside portion of a flange of the electrical enclosure, and wherein the bottom side is configured to be movably coupled to a second outside portion of an opposing flange of the electrical enclosure, wherein the top side, the bottom side, and the back side each have an inner surface;
- a fastener receiver positioned between the flange and the opposing flange and configured to be coupled to the flange, wherein the fastener receiver is positioned adjacent to the inner surfaces of the bracket;
- a first fastener positioned on a third outside portion of the back side of the bracket and hingedly coupled to the fastener receiver, wherein the first fastener traverses an aperture in the bracket;
- a securing device that movably abuts against the back side of the bracket;
- and
- a cam configured to be mounted on the electrical enclosure and that is hingedly coupled to the securing device, wherein rotation of the cam moves the securing device relative to the back side of the bracket,
- wherein the bracket, through the first fastener and the fastener receiver, is configured to remain coupled to the electrical enclosure when the securing device does not abut against the back side of the bracket.
