摘要： A blind rivet is injection molden from plastic material. It comprises a female member molded about a male member. The female member is comprised of a flexible tubular wall and a flange about the upper end thereof, the wall defining a stepped portion in the axial bore thereof at the upper end and a plurality of elongate perforations about the wall. The male member is comprised of a shank in the axial bore and axially movable in relation to the tubular wall, an enlarged head at one end in intimate contact and engagement with the lower end of the female member, and a head portion at the other end and protruding from the upper end of the female member. The head portion is shaped to be gripped by a tool for pulling the shank axially through the bore and the shank has a series of peripheral claws each forming a shoulder facing the lower end so that, upon pulling, the perforated flexible tubular wall collapses and expands radially and successive claws snap their respective shoulders into engagement with the shoulder of the stepped portion, the engagement of the shoulders maintaining the tubular wall of the female member radially expanded and locking the male member against axial movement towards the lower end of the female member.
摘要翻译：盲铆钉是由塑料材料注塑成型的。它包括模制在男性构件上的女性构件。阴构件由柔性管状壁和围绕其上端的凸缘构成，该壁在其上端在其轴向孔中限定了阶梯部分，以及围绕壁的多个细长穿孔。阳构件包括轴向孔中的柄部并且可相对于管状壁轴向移动，一端的扩大头部与阴构件的下端紧密接触并接合，另一端的头部部分并从阴构件的上端突出。头部被成形为被工具夹持，用于将柄轴向地穿过孔，并且柄具有一系列周向爪，每个周向爪形成面向下端的肩部，使得在拉动时，穿孔柔性管状壁塌缩并膨胀径向和连续的爪将其各自的肩部卡扣与阶梯部分的肩部接合，保持阴构件的管状壁的肩部的接合径向膨胀并且锁定阳构件以抵抗朝向阴构件的下端的轴向运动。
