Abstract
The present invention discloses a blind bolt fastening device, and belongs to the technical field of bolts. The blind bolt fastening device includes Z-shaped gaskets, a fixed plate, elastic hinges, a screw cap, a nut, an integrated gasket and the like. The top end of the screw cap is connected to the fixed plate in a spot welding manner. A plurality of elastic hinges is uniformly mounted on the fixed plate. One end of each elastic hinge is rotatably fixed on the fixed plate. Connection points of the elastic hinges and the fixed plate do not exceed the outer edge of the fixed plate. The other end of each elastic hinge is connected to one Z-shaped gasket in a spot welding manner. In an initial state, the plurality of Z-shaped gaskets are uniformly distributed and fitted onto the outer wall of the screw cap along a circumferential direction. When needing to pass through amounting hole, the plurality of Z-shaped gaskets may be folded through the elastic hinges to the top end of the screw cap and form elastic potential energy for rebounding. The present invention realizes simple and quick single side installation of a bolt and may be widely applied to civil and architectural engineering…
