摘要： A grommet has a female member and a male member. Each member consists of a sleeve with a flange formed at one end. The sleeve of the male member is slightly smaller than the bore of the sleeve of the female member. A locking mechanism for the grommet consists of an annular groove inscribed within the inner surface of the sleeve of the female member and a slightly-offset, matching annular lip formed upon the outer surface of the sleeve of the male member. The annular groove and annular lip are offset so that the two members remain in tension, pulling toward one another when the grommet is locked in place. The grommet is locked in place by inserting the male member into the female member and urging them together until the annular lip fits within the annular groove. The grommet may be disassembled by placing a dowel or like object against the non-flanged end of the male member and striking the male member or otherwise applying a force thereto. The flange of the male member and the flange of the female member may each have an annular indentation on their respective bottom surfaces that separates each bottom surface into an outer annular bottom surface and an inner annular bottom surface. This indentation allows each flange to flex slightly and creates a snug fit of the flanges against the side of a partition, wall or other surface through which the grommet has been placed.

摘要翻译： 索环有女性成员和男性成员。 每个构件由在一端形成有凸缘的套筒组成。 阳构件的套筒略小于阴构件的套筒的孔。 用于索环的锁定机构包括内凹在阴构件的套筒的内表面内的环形槽和形成在阳构件的套筒的外表面上的略微偏移的匹配环形唇缘。 环形槽和环形唇缘偏移，使得两个构件保持张紧，当索环被锁定就位时彼此相向拉动。 通过将阳构件插入阴构件并将其推动在一起直到环形唇缘配合在环形槽内，将索环锁定就位。 可以通过将销钉或类似物体放置在阳构件的非凸缘端部上并撞击阳构件或以其它方式向其施加力而将索环拆卸。 阳构件的凸缘和阴构件的凸缘可以在其各自的底表面上各自具有环形凹部，其将每个底表面分隔成外环形底表面和内环形底表面。 这种压痕允许每个凸缘稍微弯曲并且产生凸缘的紧贴配合在隔离物，壁或其它表面上，垫圈已经放置在该侧面上。
