Document Type and Number:
WIPO Patent Application WO/2018/090427
Kind Code:
A1
Abstract:
A fastener (10) is provided, comprising: a tightening member (1), constructed to mate with a mating screw (100) to fasten a fastened member, wherein a first joint surface is formed on a first end surface of the tightening member (1); and an annular member (2), wherein the annular member (2) and the tightening member (1) are coaxial, a first recessed portion (21) is formed on a first side of the annular member (2), and a second joint surface is formed on a bottom of the first recessed portion (21). The first joint surface is accommodated in the first recessed portion (21), and the first joint surface mates with the second joint surface, such that the tightening member (1), when loose, is prevented from being further loosened. The fastener of the present invention can fix a nut or a bolt head more stably, and hide a joint surface between the nut or the bolt head and the annular member in the annular member, thereby reducing the possibility of the performance of the fastener being affected by foreign matter entering into a space between the joint surfaces when in poor working conditions, making the fastener more stable and reliable.
