The invention discloses a wedge block cabin connection device. At first, an airtight anchor nut is riveted on a designated position on the inner surface of a rear cabin through a rivet; when a front cabin is sleevedly connected to the rear cabin, a first wedge block, a second wedge block, a third wedge block, and a fourth wedge block are installed into the cavity through a press cover groove, wherein the first wedge block and second wedge block are pushed in to the cavity in a clockwise direction, the third wedge block and the fourth wedge block are pushed into the cavity in a counter-clockwise direction, the wedge blocks radially move to the designated positions, and through the contact slopes between the wedge blocks, two cabins are tightly pressed. A press cover is fixed on the press cover groove, the flatness of the outer surface can be guaranteed, and finally a screw is screwed into the anchor nut. The provided wedge block cabin connecting device has the advantages of large force-transmission contact area, simpleness, reliability, and simple and convenient assembly technology. The wedge blocks can be conveniently disassembled by a screw-driver groove in the wedge blocks after the screw is unscrewed.
