Title:
FASTENING PIECE WITH MALE THREAD AND THREAD FASTENING COMPONENT
Document Type and Number:
WIPO Patent Application WO/2012/079299
Kind Code:
A1
Abstract:
A fastening piece with a male thread and thread fastening components are disclosed. The fastening piece fits with a fastening piece with a female thread by the interaction between the male thread and the female thread. Each tooth shape of the male thread comprises a leading flank and a following flank, and the male thread also comprises a slant extending between the leading flank and the following flank; comparing the joining of the slant of the male thread and the leading flank with the joining of the slant of the male thread and the following flank, the former is more far away from the axis of the male thread; and the slant of the male thread and the slant of the female thread are fitting together. Thus by using the cooperation of the male thread of the invention and the female thread of the Spiralock, the contact surfaces between the male thread and the female thread are not easy to be stripped, the axial force of the male thread can be maintained in the process of the use of the fastening piece, and the clamping force of the fastening piece with the female thread can be maintained.
