The invention discloses a screw buckling structure for stabilizing a cabinet door. The screw buckling structure for stabilizing the cabinet door comprises two cabinet body assemblies which are symmetrically arranged, wherein each cabinet body assembly comprises a door board and a side surface cabinet board which are connected through a screw buckling assembly; each screw buckling assembly comprises a screw sleeve and a screw body; the screw sleeves are arranged on the side surface cabinet boards, and circular arc shaped slots are formed in the screw sleeves; the rear end of each screw body is arranged on the corresponding door board, and the front part of the each screw body is circular arc shaped and is matched with the corresponding circular arc shaped slot in the corresponding screw sleeve; a first magnet body is arranged at the front end of each screw body; a second magnet body is arranged at the deepest part of each circular arc shaped slot; a third magnet body is arranged on one side, close to each other, of each of the door boards; when the door boards are opened, the screw bodies can be driven by the door boards to extend deep in the corresponding circular arc shaped slots, thus the first magnet bodies and the second magnet bodies can be close to each other and attract each other, and as a result, the door boards can be positioned, and goods can be conveniently picked; when the door boards are closed, the third magnet bodies on the two door boards can attract each other, so that an inner space of the whole cabinet body can be closed. The whole screw buckling structure is simple, convenient to use, low in manufacturing cost, and wide in applicable scope.
