Abstract

本实用新型无方接箍扳手，包括壳体，壳体设有中孔为圆形接箍套入孔，在套入孔圆周方向上于壳体内通过销轴均布安装有两个滚轮和一个偏心轮，滚轮和偏心轮外沿与壳体中孔相切，偏心轮连接手把。提起手把，偏心轮最小半径向下，圆弧面处在最高位置，接箍通过壳体中孔，扳手套在接箍上；压下手把，偏心轮圆弧逐渐接触接箍外圆表面，按顺时针方向转动，接箍上扣旋紧到抽油杆上；按逆时针方向转动，接箍卸扣从抽油杆上卸下。本实用新型能将无(扳手)方接箍装配到抽油杆上或从抽油杆上卸下。其特点是轻捷、方便，不伤接箍表面。

Description

无方接箍扳手
技术领域
本实用新型涉及一种扳手，特别涉及一种油井抽油杆产品与无方接箍装配用的无方接箍扳手。
背景技术
抽油杆产品装配中，无(扳手)方接箍在与抽油杆装配或拆卸中不象有(扳手)方接箍一样可以用普通扳手旋紧和拆卸。无扳手方接箍的上、卸扣，无专门工具，用普通管子钳旋紧和拆卸又会磕伤接箍。
发明内容
本实用新型所要解决的技术问题是提供一种无方接箍扳手，使用轻捷、方便，不伤接箍表面。
本实用新型无方接箍扳手，其特征在于包括壳体，壳体设有中孔为圆形接箍套入孔，在套入孔圆周方向上于壳体内通过销轴均布安装有两个滚轮和一个偏心轮，滚轮和偏心轮外沿与壳体中孔相切，偏心轮连接手把。
其工作原理为：提起手把，偏心轮最小半径向下，圆弧面处在最高位置，接箍通过壳体中孔，扳手套在接箍(接箍已套在抽油杆上)上；压下手把，偏心轮圆弧逐渐接触接箍外圆表面，按顺时针方向转动，接箍上扣旋紧到抽油杆上；按逆时针方向转动，接箍卸扣从抽油杆上卸下。
本实用新型的优点：
本使用新型能将无(扳手)方接箍装配到抽油杆上或从抽油杆上卸下。其特点是轻捷、方便，不伤接箍表面。

图2为壳体侧视图。
图中：1 壳体  2 销轴  3 滚轮  4 偏心轮  5 手把  6 接箍
具体实施方式
如图所示，本实用新型的无方接箍扳手，包括壳体1，壳体1设有中孔为圆形接箍套入孔，在套入孔圆周方向上于壳体内通过销轴2均布安装有两个滚轮3和一个偏心轮4，滚轮3和偏心轮4外沿与套入孔相切，偏心轮4连接手把5。滚轮3的作用主要是起支撑作用。
提起手把5，偏心轮4最小半径向下，圆弧面处在最高位置，接箍6通过壳体中孔，扳手套在接箍6上(也即接箍套在壳体中孔内)，接箍是套在抽油杆上。压下手把5，偏心轮4圆弧逐渐接触接箍6外圆表面，按顺时针方向转动，接箍上扣旋紧到抽油杆上；按逆时针方向转动，接箍卸扣从抽油杆上卸下。
