The invention is applicable to the field of refrigerators and discloses a connecting seat, a supporting component, a drawer type door body and a refrigerator. The connecting seat comprises a base plate, a seat body connected with a drawer guide rail and at least two plug boards connected with a door frame in a card-inserting manner; the seat body is convexly arranged on one side of the base plate in the thickness direction of the base plate; the plug boards are arranged and distributed at one end of the base plate in the length direction of one edge of the base plate at intervals; the at least two plug boards are arranged in a mutually-staggered manner in the thickness direction of the base plate. When the connecting seat and the door frame are assembled, only the plug boards of the connecting seat are required to be connected with the door frame in a card-inserting manner, and the assembly operation is very simple and convenient. As the connecting seat is only connected with a frame bar of the door frame, the assembly of the connecting seat is not affected by the height of the door frame, and the connecting seat can be applicable to drawer type door bodies with different heights. In addition, as the at least two plug boards are subjected to reverse pre-pressure in the thickness direction of the base plate, the stability and the reliability of connection between the connecting seat and the door frame are fully guaranteed.
