A cabinet framework, comprising:

• a front door frame;
• a rear door frame;
• depth components;
• wherein the front door frame and the rear door frame are arranged oppositely;
• the depth components are connected between the front door frame and the rear door frame;
• the front door frame comprises four first section bars connected end to end, and the first section bars are connected by two-way components comprising two sockets with insertion directions perpendicular to each other;
• the first section bar comprises a rectangular hollow beam formed by folding a rectangular sheet and is connected to the two-way component by insertion at the socket
• the rectangular sheet comprises a first edge and a second edge connected together, the first edge wraps around the second edge to form a flange extending along an axial direction of the first section bar, and the flange has multiple rectangular through holes arranged along the first section bar, with the rectangular through holes comprising step holes;
• the diameter of the rectangular through holes on the first edge is greater than the diameter of the rectangular through holes on the second edge;
• the front door frame and the rear door frame have the same structure;
• and
• wherein the depth component comprises one bottom plate, two reinforcing columns, and two supporting pieces;
• the bottom plate is rectangular;
• the two sides of the bottom plate that extend along a longitudinal direction comprise two accommodating cavities that extend along the longitudinal direction;
• the two reinforcing columns are respectively accommodated in the two accommodating cavities along the longitudinal direction of the bottom plate;
• pin holes are respectively arranged at the two ends of one of the reinforcing columns;
• a positioning cylinder working with the pin hole is fixed on the two-way component;
• the two supporting pieces are respectively arranged at the two ends of the bottom plate along the longitudinal direction;
• the supporting pieces are clamped between the two accommodating cavities;
• one trimming positioning pin and one screw hole are arranged on one side of the supporting piece that is far from the bottom plate;
• the trimming positioning pin is inserted in the rectangular through hole;
• and the screw hole is connected to the corresponding rectangular through hole on the flange by using a screw.
