"The Ring belt safety explosion-proof" seems to protect to the "utility model" refers to the production of personal protective equipment, namely the design of safety belts explosion-proof. The problem of the proposed utility model - perform security requirements GOST 51330.13-99 (IEC 60079-96) classes for zones 1, 2, indoor and outdoor installations with category 2A explosive mixture when using explosion-proof safety belts, providing strength and reliability when used as directed. Technical result is achieved by the "explosion-proof safety belt ring" is made of circular section steel core which is placed in a copper tube, a replacement cover. The application of a copper pipe as a coating, the thickness of the protective layer is equal to the thickness of the tube wall, will be 800-1000 microns. In the first embodiment, "explosion-proof safety belt ring" is made of steel of circular cross section of the core, which is placed in a copper pipe, wherein the ring is oval. In the second embodiment, "explosion-proof safety belt ring" is made of steel of circular cross section of the core, which is placed in a copper pipe, wherein the ring formed D-shaped core and the ends are welded to the straight part of the ring. The presence of circular section steel core provides strength. design "ring belts safety flameproof". Copper tube prevents sparking that allows the use of a ring in explosive environments, ensuring safety of the structure of the claimed utility model. Welded steel core 2 embodiment enables the use of the power ring as the fastening element for attaching a cable thereto, ensuring reliability.
