Document Type and Number:
WIPO Patent Application WO/2018/070696
Kind Code:
A1
Abstract:
The present invention relates to a bolt assembly having a non-loosening nut and, more particularly, a bolt assembly having a non-loosening nut in which a pair of non-loosening nuts that move along a male thread pitch of a bolt are prepared so that the pair of non-loosening nuts press and spread to each side a pair of adjacent male threads of the bolt, thereby restricting the rotation of the bolt to suppress the loosening of the bolt. To this end, the present invention provides the bolt assembly having the non-loosening nut, the bolt assembly comprising: a bolt including a first male thread; a first nut, which has a first female thread screw-coupled to the first male thread of the bolt, and has, on the outer circumferential surface, a second male thread formed in the direction opposite to the first male thread; and a second nut, which has a second female thread that is screw-coupled to the second male thread of the first nut, and has, in the center, a non-loosening female thread which corresponds to the first female thread and is screw-coupled to the first male thread via the first female thread. The bolt assembly having the non-loosening nut is characterized in that the groove depth of the non-loosening female thread is formed deeper than the groove depth of the first male thread, thereby forming a gap between the first male thread and the non-loosening female thread, while preventing a gap from being formed between the first female thread and the first male thread.
