Abstract

本实用新型公开了一种固定式防偏磨接箍,包括接箍本体,其特点是在接箍本体的中部固定有耐磨套,在耐磨套上间隔90°角设置有防磨凸棱。本实用新型结构简单,设计新颖,能有效避免接箍与井下油管线之间的磨损。

Description

固定式防偏磨接箍
一、技术领域:本实用新型涉及一种油田用抽油杆接箍,特别涉及一种固定式防偏磨接箍。
二、背景技术:目前,现有接箍在油管内随着抽油杆上下往复工作时,会和油管内壁发生强烈的磨擦,导致接箍磨损严重,甚至出现断杆、抽油管壁磨损等现象。
  三、发明内容:本实用新型的目的就在于提供一种能防止接箍和抽油管壁磨损的接箍——固定式防偏磨接箍。本实用新型的技术解决方案是:所述接箍主要包括接箍本体,在接箍本体的中部固定有耐磨套,在耐磨套上设置有防磨凸棱;防磨凸棱间隔90°角设置在耐磨套上。本实用新型结构简单,设计新颖,耐磨,有效地减轻了接箍与井下油管线的磨损,避免了断杆及抽油管壁磨损的现象,延长了油管的使用寿命。
四、附图说明:图1是本实用新型实施例主视结构剖视示意图;
    图2是图1中A-A剖视结构示意图。
五、具体实施方式:参照附图,本实用新型主要包括接箍本体1,在接箍本体1沿长度方向的中部处固定有耐磨套2,在耐磨套2上间隔90°角设置有四个防磨凸棱3。耐磨套2和防磨凸棱3采用聚乙烯耐磨材料制成,避免了接箍与井下油管线钢件间的磨擦,防止了抽油管壁和接箍的磨损。
