FIELD: methods of explosion protection.
SUBSTANCE: invention relates to explosion-proof housing (10) with housing opening (11), which limits inner cavity (13) and has housing opening (14). Housing opening (14) can be closed by cover (17). In the closed position of cover (17) between housing element (11) and, first of all, between housing flange (15) of housing element (11) and cover (17), gap (18) which is safe with respect to flame breakthrough is formed. Housing element (11) has several body walls (12), which have such a small wall thickness s that body walls (12) would not withstand the explosion pressure in inner cavity (13). Therefore, housing element (11) is reinforced by means of reinforcing frame (30) located outside inner cavity (13). Reinforcing frame (30) has an annular frame part (31) located near housing opening (14) and completely enclosing housing element (11). First of all, annular frame part (31) is directly adjacent to housing flange (15).
EFFECT: disclosed is an explosion-proof housing with a reinforcing frame.
