Abstract

The invention provides a unidirectionally-assembled fastening bolt used for fastening connecting between thin plates, and relates to the field of bolt connecting. The unidirectionally-assembled fastening bolt used for fastening connecting between the thin plates comprises a bolt and a clamp. The bolt comprises a screw cap. A boss is arranged at the top of the screw cap. The upper surface of the boss is fixedly connected with a screw. A first through hole is formed in the outer surface of the screw. A second through hole is formed in the position, close to the top, of the outer surface of the screw. The outer surface of the screw is in threaded connection with a nut. A gasket is arranged between the nut and the screw cap. Through structural reasonable design on the clamp and the bolt, the structure is simple, and use is convenient; and through simple operation, bolt fastening under the half-sealed situation can be completed, and the problems that under the half-sealed situation, the bolt cannot be mounted in, one end of the bolt cannot be fixed, and consequently the bolt and the nut rotate at the same time are solved.

Description

technical field [0001] The invention relates to the technical field of bolt connection, in particular to a unidirectional assembly fastening bolt used for fastening connection between thin plates. Background technique [0002] In the installation process of sheet metal or thin plate, it is necessary to use bolts and nuts to fasten the two connected parts. When performing fastening operations, it is generally necessary to fix the bolts (nuts) and then use a wrench to tighten the nuts (bolts), but When one side of the connected part is closed, because the outer diameter of the bolt head is larger than the outer diameter of the threaded rod, the bolt cannot be installed. Even if the bolt is installed, the purpose of fixing the bolt or nut cannot be easily achieved. At this time, the bolt and nut It will rotate at the same time when tightening, and the fastening effect cannot be achieved. At this time, a bolt that can be put in and tightened in a semi-closed situation is needed ...
