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 a plurality of first apertures traversing therethrough;
- an opposing flange that abuts the flange, wherein the opposing flange comprises a plurality of cavities traversing therethrough;
- and
- a plurality of fastening devices, wherein each fastening device of the plurality of fastening devices comprises:
- a fastener receiver disposed in a cavity of the plurality of cavities disposed in the opposing flange, wherein the fastener receiver comprises a second aperture that traverses a height of the fastener receiver;
- and
- a fastener comprising a head, a base, and a stem, wherein the head is mechanically coupled to a first end of the stem, wherein the base is mechanically coupled to a second end of the stem, wherein the head abuts against the flange, wherein the stem traverses a first aperture of the plurality of first apertures and the second aperture of the fastener receiver, and wherein the base abuts against an outer surface of the fastener receiver.
A system for fastening a cover to a body of an enclosure, comprising:
- a flange comprising a plurality of first apertures traversing therethrough;
- an opposing flange that abuts the flange, wherein the opposing flange comprises a plurality of second apertures traversing therethrough and a plurality of cam features;
- and
- a plurality of fastening devices, wherein each fastening device of the plurality of fastening devices comprises:
- a stem;
- a head, wherein the head is mechanically coupled to a first end of the stem;
- and
- a base, wherein the base is mechanically coupled to a second end of the stem,
- wherein the head abuts against the flange, wherein the stem traverses a first aperture of the plurality of first apertures and a second aperture of the plurality of second apertures, and wherein the base abuts against an end of a cam feature of the plurality of cam features.
A fastening device comprising:
- a stem;
- a head, wherein the head is mechanically coupled to a first end of the stem;
- and
- a base, wherein the base is mechanically coupled to a second end of the stem,
- wherein the head is configured to abut against an opposing flange of an enclosure, wherein the stem is configured to traverse a first aperture of a plurality of first apertures disposed in the flange, wherein the stem is further configured to traverse a second aperture of a plurality of apertures disposed in an opposing flange of the enclosure, and wherein the base is configured to be coupled to an outer surface of the opposing flange of the enclosure.
