| 摘要 |
<p>The invention relates to a push-in plug (1) made from plastics and having at least one shank (2) to be introduced into a drilled hole, on which shank (2) there are located expansion segments (4) lying opposite one another in pairs, which are braced against and wedge against the wall of the drilled hole when a tensile force acts on the shank (2). For improvement of the holding force, the expansion segment (4) is formed by a wedge element (5), which is held on the outer surface (3) of the shank (2) so as to be axially displaceable and which is displaced, when the push-in plug (1) is pushed into the drilled hole, into a position lying in front of an inclined surface (6) formed on the shank (2), which inclined surface (6) rises towards the insertion end (14) of the push-in plug (1).</p> |
