Inserting connection piece and prefabricated part combination assembly
The invention discloses an inserting connection piece and a prefabricated part combination body. The inserting connection piece comprises an outer sleeve body, a stopping piece, an inserting column and a wedging body, wherein an inserting cavity is formed in the outer sleeve body, the stop piece is arranged at one end of the outer sleeve body, a reverse stop face with the inner diameter gradually increased in the direction away from the outer end is formed at the inner end of the stop piece, the inserting column is provided with a first reducing part and a second reducing part, an anti-falling clamping surface is formed on the outer surface of the first reducing part, the wedging body is arranged in the outer sleeve body, and the difference value delta R between the inner radius R1 of an inserting cavity and the maximum outer radius R2 of the inserting end is larger than the radial maximum width value W of the wedging body and smaller than the axial maximum height value H of the wedging body. The wedging body of the inserting connection piece is not prone to toppling or falling in the plug-in process, and therefore the inserting success rate and the connection reliability after inserting can be remarkably improved.
本发明公开了一种插接连接件及预制构件组合体，所述插接连接件包括：外套体、止挡件、插柱和楔入体，所述外套体内部形成有插接腔；所述止挡件设于所述外套体的一端，其内端上形成沿远离外端方向内径逐渐增大的逆向止挡面；所述插柱具有第一变径部和第二变径部，所述第一变径部的外表面形成有防脱卡接面；所述楔入体内置于所述外套体；所述插接腔的内半径R1和所述插接端的最大外半径R2的差值△R大于所述楔入体的径向最大宽度值W且小于所述楔入体的轴向最大高度值H。该插接连接件的楔入体在插接过程中不易出现倾倒或掉落现象，从而可显著提高插接的成功率和插接后的连接可靠性。
