Abstract
The utility model discloses a bolt assembly capable of being installed in one direction. The bolt assembly comprises a component provided with a mounting hole, a bolt, a special-shaped nut which can be in threaded connection and fit with the bolt and can penetrate through the mounting hole, and a swing piece which can penetrate through the mounting hole and can abut against the lower side of the mounting hole. The swing piece is connected on the special-shaped nut in a rotating mode. The special-shaped nut is connected on the bolt through threads. The bolt penetrates through the mounting hole so that the swing piece and the special-shaped nut are enabled to penetrate through the mounting hole and be located on the lower side of the mounting hole. The bolt is lifted to enable the swing piece to abut against the lower side of the mounting hole, and then the bolt is rotated until the bolt and the special-shaped nut are tightly screwed. The bolt assembly capable of being installed in one direction is simple in structure, low in cost, convenient to use and install and suitable for any component which can be installed only in one direction, for example, a toilet bowl, and has few parts.
