Description

钢套钢塑弹性体保护器
本实用新型钢套钢塑弹性体保护器,用于石油套管和各种管材的端部外螺纹的保护。
目前国内外同类产品有全钢体保护环或钢塑体保护环,全钢体保护环具有硬度强,容易对所保护的螺纹造成损坏,并且成本高,加工难度大。钢塑体保护环是将金属件夹在塑料体的中间,因外部是塑料体,抗冲击能力较差,特别是对气候条件恶劣,温差大的中东一些国家和我国新疆等地区的适应能力较差。
本实用新型的目的是提供一种钢套钢塑弹性体保护器,采用了钢套与塑料体燕尾状连接,一次注塑成型,加强抗冲击能力,降低产品成本。
本实用新型钢套钢塑弹性体保护器,发明的目的是这样实现的,保护环钢套厚为4毫米至10毫米之间,并在钢套内璧设有燕尾槽五道,钢套两端面设子口燕尾槽(5)各一道,增加钢塑附着力,使注塑体与钢套形成整体,注塑体外壁上并带有螺纹,与各种管材端部内螺纹相符合。
本实用新型钢套钢塑弹性体保护器,优点在于:柔钢结合,即有效地保护了管体端部的螺纹,又具有很强的抗冲击能力,适用于各种气候环境地区。
本实用新型钢套钢塑弹性体保护器有以下示图及实施例给出。
图1为本实用新型钢套钢塑弹性体保护器的主视图带半剖。
图2为本实用新型钢套钢塑弹性体保护器的俯视图。
本实用新型钢套钢塑弹性体保护器,是由钢套(1)、注塑体(2)构成,钢套(1)内璧设有五道燕尾槽(3),注塑体(2)内壁上带有螺纹(4)、上部内设环形筋(6)一道,钢套(1)与注塑体(2)、螺纹(4)、环形筋(6)为一次注塑成型。
