High-strength quake-proof cabinet

The utility model discloses a high-strength quake-proof cabinet, which relates to the storing field of electric equipment. The high-strength quake-proof cabinet comprises a cuboid frame body, a top plate and a base, wherein the cuboid frame body is used for accommodating the equipment; the top plate and the base are respectively arranged the upper end and the lower end of the frame body; the frame body consists of two opposite side frames and a beam used for connecting the two side frames; each of the side frames comprises two parallel columns and a reinforced column, wherein the reinforced column is arranged between the two parallel columns, the parallel columns are fixed with the reinforced column by a rectangular side beam; and the beam is connected with the columns arranged at one side of each of the two side frames and the middle reinforced column. The cabinet designed by the scheme can ensure that only 0.5-degree deformation of the cabinet is caused when in an earthquake, the cabinet can protect internal equipment well, and the whole frame eliminates other auxiliary reinforced structures, so that the installation of the cabinet and the disassembly/assembly of the internal equipment are convenient, the utilization rate of the inner space of the cabinet is improved, and the natural frequency of the whole frame in the scheme in three directions can be over 21Hz after experiment.
