为实现上述目的，本发明提出了一种管件密封连接头，包括管接头本体、连接插头体、活接螺母、钢珠、第一密封圈和第二密封圈，所述管接头本体的外壁上设有与活接螺母配合的连接螺纹面，所述管接头本体的内壁设有第二环形卡槽，所述第二环形卡槽内设有第一密封圈，所述管接头本体的端部设有第一锥形面，所述第一锥形面内设有第一环形卡槽，所述第一环形卡槽内设有第二密封圈，所述活接螺母内嵌装有连接插头体，所述连接插头体上设有定位凸体，所述定位凸体与活接螺母的挡边相配合，所述连接插头体的左端设有插接部，所述插接部与有第一锥形面相配合，所述插接部内设有若干个钢珠，所述钢珠与管接头本体的端面相配合。
作为优选，所述插接部的外壁设有第二锥形面，所述第二锥形面与有第一锥形面相配合，所述插接部的内壁设有第三锥形面，所述第三锥形面与钢珠相配合。
作为优选，所述第一锥形面与第二锥形面的锥度相同。
作为优选，所述定位凸体为环形凸体，所述定位凸体的截面形状为矩形，所述定位凸体的右壁紧贴挡边。
作为优选，所述连接插头体右端的拐角设有圆弧过渡。
本发明的有益效果：本发明通过管管接头本体、连接插头体、活接螺母、钢珠、第一密封圈和第二密封圈的配合，利用双重密封圈提高了接头与管的连接密封性，避免连接***发生泄漏问题，利用连接插头体与钢珠配合，楔形面对钢珠具有径向的预紧力锁紧管件，避免振动引起连接的松动。
本发明的特征及优点将通过实施例结合附图进行详细说明。
【附图说明】
图1是本发明一种管件密封连接头的结构示意图。
图中：1-管接头本体、2-连接插头体、3-活接螺母、4-钢珠、5-第一密封圈、6-第二密封圈、11-第一锥形面、12-端面、13-第二环形卡槽、14-第一环形卡槽、21-插接部、22-第三锥形面、23-第二锥形面、24-圆弧过渡、25-定位凸体、31-挡边。
【具体实施方式】
参阅图1本发明一种管件密封连接头，包括管接头本体1、连接插头体2、活接螺母3、钢珠4、第一密封圈5和第二密封圈6，所述管接头本体1的外壁上设有与活接螺母3配合的连接螺纹面，所述管接头本体1的内壁设有第二环形卡槽13，所述第二环形卡槽13内设有第一密封圈5，所述管接头本体1的端部设有第一锥形面11，所述第一锥形面11内设有第一环形卡槽14，所述第一环形卡槽14内设有第二密封圈6，所述活接螺母3内嵌装有连接插头体2，所述连接插头体2上设有定位凸体25，所述定位凸体25与活接螺母3的挡边31相配合，所述连接插头体2的左端设有插接部21，所述插接部21与有第一锥形面11相配合，所述插接部21内设有若干个钢珠4，所述钢珠4与管接头本体1的端面12相配合。所述插接部21的外壁设有第二锥形面23，所述第二锥形面23与有第一锥形面11相配合，所述插接部21的内壁设有第三锥形面22，所述第三锥形面22与钢珠4相配合。所述第一锥形面11与第二锥形面23的锥度相同。所述定位凸体25为环形凸体，所述定位凸体25的截面形状为矩形，所述定位凸体25的右壁紧贴挡边31。所述连接插头体2右端的拐角设有圆弧过渡24。
本发明工作过程：
本发明一种管件密封连接头在工作过程中，将管***管接头本体1，第一密封圈5与管件的外壁紧密接触，然后旋紧活接螺母3，在旋紧的过程中，活接螺母3与连接插头体2配合，挡边31驱动定位凸体25向前移动，第二锥形面23与第一锥形面11紧密接触，此时第二密封圈6的外圈挤压第二锥形面23，双重密封圈提高了接头与管的连接密封性，避免连接***发生泄漏问题，钢珠4在端面12的驱动下移向第二锥形面22，此时第二锥形面22对钢珠4产生径向的作用力，钢珠4对管件进行锁紧，利用连接插头体与钢珠配合，楔形面对钢珠具有径向的预紧力锁紧管件，避免振动引起连接的松动。
上述实施例是对本发明的说明，不是对本发明的限定，任何对本发明简单变换后的方案均属于本发明的保护范围。
