Description

钢球锁紧式管道快速接头
技术领域
本实用新型涉及管道快速接头,特别是涉及钢球锁紧式管道快速接头。 
背景技术
在管道安装时,为了使管道安装方便,提高管道安装效率,人们设计了快速接头,已有快速接头的结构大多包括接头本体,在接头本体内设置呈环状分布倾斜向内的倒齿片,在倒齿片位于接头本体口部一侧设置卸套,安装水管时,由水管往里推使倒齿片张开,拔出时由于倒齿片卡在水管外壁,不能拔出,达到快速连接的目的,万一要将水管拔出,利用管径大于水管的卸套往里压,通过卸套使倒齿片张开失去对管壁的卡紧力,从而将水管拔出,该结构存在的缺点是:倒齿片仅能卡住硬度较低材料所制成的水管,而不锈钢管、铁管等硬度高的水管则不能适用,并且倒齿片容易划伤水管表面,影响水管的密封性。 
发明内容
本实用新型的目的是为了克服已有技术存在的缺点,提供一种结构简单,卡紧可靠,拆卸方便,不划伤水管表面,适用于不同硬度的水管的钢球锁紧式管道快速接头。 
本实用新型钢球锁紧式管道快速接头的技术方案是:其特征在于包括接管,在接管上制有外凸的锥形接头,锥形接头与接管相连的一头内径大,锥形接头往口部的一端内径逐渐缩小,在口部制有向内弯的圆环,在锥形接头内设置密封圈、钢球保持器和卸套,在钢球保持器中设置不锈钢球,不锈钢球和密封圈与水管的外壁相接触,卸套一端制有拉钩,拉钩分别与钢球保持器或锥形接头口部的圆环相接触,卸套的另一端伸出锥形接头外。 
本实用新型公开了一种钢球锁紧式管道快速接头,通过在接管上制有外凸的锥形接头,锥形接头的口部内径小,与接管相连的一头内径大,在锥形接头内设有密封圈、钢球保持器和卸套,当水管从接管的口部往里插接时,水管带动不锈钢球和钢球保持器往锥形接头内径大的一头移动,使水管能顺利***接管中,若要拔出水管,水管带动不锈钢球和钢球保持器往锥形接头内径小的一头移动,不锈钢球和钢球保持器与锥形接头内壁的锥面相接触,通过锥面使不锈钢球和钢球保持器对水管越夹越紧,从而使水管无法拔出,而利用工具(即一块开口的压板),将卸套往里压,通过卸套的拉钩往将不锈钢球和钢球保持器推至锥形接头内径大的一头,不锈钢球与水管之间配合便不紧密了,水管就能轻易拔出。本方案钢球锁紧式管道快速接头,采用锥形接头内壁的锥面与不锈钢球配合,结构简单,***轻松,卡紧可靠,拆卸方便,不锈钢球与水管表面接触不会划伤水管表面,保证其与密封圈接触的密封性,并且可适用于不同硬度的水管,通用性好。 
附图说明
图1是本实用新型钢球锁紧式管道快速接头的结构示意图; 
图2是钢球锁紧式管道快速接头与水管配合状态结构示意图。
具体实施方式
本实用新型涉及一种钢球锁紧式管道快速接头,如图1—图2所示,其特征在于:包括接管1,在接管上制有外凸的锥形接头2,锥形接头与接管相连的一头内径大,锥形接头往口部的一端内径逐渐缩小,在口部制有向内弯的圆环3,在锥形接头2内设置密封圈4、钢球保持器5和卸套6,在钢球保持器中设置不锈钢球7,不锈钢球和密封圈与水管8的外壁相接触,卸套一端制有拉钩9,拉钩分别与钢球保持器5或锥形接头2口部的圆环3相接触,卸套6的另一端伸出锥形接头外。通过在接管1上制有外凸的锥形接头2,锥形接头的口部内径小,与接管1相连的一头内径大,在锥形接头内设有密封圈4、钢球保持器5和卸套6,当水管8从接管1的口部往里插接时,水管带动不锈钢球7和钢球保持器5往锥形接头2内径大的一头移动,使水管8能顺利***接管1中,若要拔出水管,水管带动不锈钢球7和钢球保持器5往锥形接头2内径小的一头移动,不锈钢球和钢球保持器与锥形接头内壁的锥面相接触,通过锥面使不锈钢球和钢球保持器对水管越夹越紧,从而使水管无法拔出,而利用工具(即一块开口的压板),将卸套6往里压,通过卸套的拉钩9往将不锈钢球7和钢球保持器5推至锥形接头2内径大的一头,不锈钢球7与水管8之间配合便不紧密了,水管8就能轻易拔出。本方案钢球锁紧式管道快速接头,采用锥形接头2内壁的锥面与不锈钢球7配合,结构简单,***轻松,卡紧可靠,拆卸方便,不锈钢球与水管8表面接触不会划伤水管表面,保证其与密封圈4接触的密封性,并且可适用于不同硬度的水管,通用性好。
