Description

抽油杆空心导向器
技术领域
本实用新型提供的是机械领域的石油机具,具体地说是抽油杆空心导向器。
背景技术
在本实用新型提出以前,油田所用的抽油杆导向器通常为实心结构。由于抽油杆导向器内为实心结构,生产时耗用材料多,成本高,且容易变形,加工难度大。
发明内容
为了克服现有技术的缺点,本实用新型提供一种抽油杆空心导向器。该导向器通过在导向器内部设计成为空心结构解决节省材料、降低成本和提高强度的技术问题。
本实用新型解决技术问题所采用的方案是:在导向器体内依次通过压盖、挡片、密封圈及防尘挡盖安装有万向轴,两个万向轴分别与各自导管相连接,在导管内设有导管孔,两个万向轴方向相反对称安装在导向器体内。
本实用新型的导向器制造材料省、成本低及强度高,并且所设的导管孔可以穿接电缆。适宜抽油杆的导向连接应用。
附图说明
图1为本实用新型结构图
图中,1.导向器体,2.万向轴,2.1.导管,  3.压盖,4.挡片,5.密封圈,6.防尘挡盖,7.导管孔。
具体实施方式
据图1所示,在导向器体1内依次通过压盖3、挡片4、密封圈5及防尘挡盖6安装有万向轴2,两个万向轴分别与各自导管2.1相连接,在导管内设有导管孔7,两个万向轴及导管方向相反对称安装在导向器体内。
