Abstract: An electrical apparatus comprises a casing and a fan-fastening base. The casing has a first opening, at least one second opening and a first connecting portion. The second opening connects to a first side of the first opening. The fan-fastening base has at least one hook portion, a first surface and a second connecting portion. At least one fan is fastened to the first surface of the fan-fastening base. The hook portion buckles in the second opening. The first surface of the fan-fastening base faces to the first opening and the second connecting portion connects to the first connecting portion.

Abstract: A rack bracket structure is applied to fix at least one electronic device onto a rack housing. The rack bracket structure includes a first bracket member, a second bracket member, a pivoting member, a plurality of first locking members and a plurality of second locking members. The first bracket member has at least one first hole and a plurality of second holes. The second bracket member has at least one third hole. The first and the second bracket members are pivoted on the pivoting member. The first locking members pass through the second holes respectively and fix the first bracket member on the electronic device. The second locking members pass through the first and the third holes respectively and fix the first and the second bracket members on the rack housing.

Abstract: A rack bracket structure is applied to fix at least one electronic device onto a rack housing. The rack bracket structure includes a first bracket member, a second bracket member, a limiting member, a plurality of first locking members and a plurality of second locking members. The first bracket member has at least one first hole and a plurality of second holes. The second bracket member has at least one third hole. The first and the second bracket members are pivoted on the limiting member. The first locking members pass through the second holes respectively and fix the first bracket member on the electronic device. The second locking members pass through the first and the third holes respectively and fix the first and the second bracket members on the rack housing.
