Abstract

本实用新型公开了一种膨胀自锁式管路连接件, 管接头体套在管路外径的凹槽上,在管接头端部的圆 锥形轴向孔里置于有弹性密封圈、膨胀圈和锁紧圈, 这种不采用螺纹连接的管路连接件可用于各种规格、 形状和各种材质的管路连接,它可极为方便地连接管 路,并提高施工效率,延长管路使用寿命。

Description

本实用新型涉及一种膨胀自锁式管路连接件,适用于各种规格、形状和各种材质的管路连接件,并可用于与管子相连的其它零部件。
现有的膨胀式管路连接件,它有一管接头体,其端部有一向外收口的截头圆锥形的轴向孔,孔内置一弹性密封圈和一可膨胀变形的压紧圈构件,压紧圈构件包括第一压紧圈和第二压紧圈。其缺点是:管接头体与管路连接时,管接头在管路上易滑动,影响安装效率,而且压紧圈需第一压紧和第二压紧,浪费原材料。
本实用新型针对上述缺点,提出一种管接头体与管路连接时,管接头在管路上不易滑动,提高安装效率,而且压紧圈不需第二次压紧,节约原材料的膨胀自锁式管路连接件。
本实用新型的任务是这样完成的,它有一管接头体,其端部有一向外收口的截头圆锥形轴向孔,孔内置一弹性密封圈,其不同特点是:管子外径的凹槽上置于有膨胀圈和锁紧圈。膨胀圈是可膨胀变形的,同时又能起到压紧。
本实用新型具有以下效果:这种不采用螺纹连接的管路连接件可用于各种规格,各种形状和各种材质的管路连接,它可极为方便地连通管路,并提高施工效率,减轻劳动强度,提高管路的抗振性和抗泄漏性,并延长管路使用寿命。
附图1是本使用新型的结构示意图;
结合以上附图详细描述实施例,管子1的外径上开有凹槽2,管接头体6的端部有向外收口的截头圆锥形轴向孔,把管接头体6套在管子1的外径上,管子1上的凹槽2与管接头体6配合,故不易滑动,弹性密封圈5和锁紧圈4膨胀圈3置于管接头体6轴向孔内,用专用工具压紧即可。
