Description

一种内螺纹保护帽
技术领域
本发明主要用于石油套管及各类管材端部的保护,使保护帽与钢管很好的结合,避免松动。
背景技术
钢管在运输过程中,极易对管端头外螺纹造成损害,为了对管头外螺纹进行保护,一般在管端头套装管帽,也即保护器。过去大都使用全钢管帽,虽然结实耐用,但加工精度要求高,否则无法配套使用。并且重量大成本高,使用不方便。
发明内容
本发明正是为了解决上述问题,提供了一种内螺纹保护帽,有效的保护钢管端面,并且拆除容易。
为了达到上述目的,本发明采取的技术方案是:
一种内螺纹保护帽,其特征是:包括钢制的支撑体,支撑体一端设有拆装槽,与拆装槽相对的另一端设有塑料连接体,该连接体底部开口形成空腔,连接体外壁靠近支撑体的一段设有外螺纹,靠近空腔开口一段为过渡段,所述的外螺纹与过渡段之间的比例为4/1~3/1。
本发明的有益效果是,采用本发明方案后,不但支撑体对帽体起到了很好的支撑作用,提高了整体强度,而且拆装方便。
附图说明
图1为本发明结构示意图。
图中:1.拆装槽;2.支撑体;3.连接体;4.外螺纹;5.过渡段。
具体实施方式
由附图1可知,本发明包括钢制的支撑体2,支撑体2一端设有拆装槽1,与拆装槽1相对的另一端设有塑料连接体3,该连接体3底部开口形成空腔,连接体3外壁靠近支撑体2的一段设有外螺纹4,靠近空腔开口一段为过渡段5,所述的外螺纹4与过渡段5之间的比例为4/1~3/1。本发明的连接体3采用注塑方式与支撑体2固接在一起,连接体3整体采用塑料材料,重量轻、塑性大,其外设外螺纹4后,可以很好的与钢管内螺纹衔接。为了与钢管内螺纹更好的衔接,方便拆装,本发明连接体3从外螺纹4一端到底部开口逐步向内缩进,使底部的开口端的直径小于顶部。同时,开口一端设有过渡段5,并未设有外螺纹,使过渡段5先放入钢管管口内再进行旋进,使其安装更加容易。
