Abstract

本实用新型涉及一种杠杆式管钳,是一种管道装卸工具。解决了管道钳方便使用的问题。技术方案为手柄6头部开有圆孔,孔内装有半圆垫圈2,该垫圈滑动套联于主钳杆1上,并装置有锁紧螺母3,在手柄6的头部用铆钉4联接有副钳口5。本实用新型产品主要用于管道的装卸。

Description

杠杆式管钳
一、技术领域
本实用新型提供一种管道钳,具体地是一种杠杆式管钳。
二、背景技术
管道钳是一种安装、拆卸管道的专用工具,目前,市面上有很多种式样的管钳在销售。用得最多的是夹紧和松开都通过锁紧螺母控制的管钳,这种管钳夹紧和松开都很吃力,使用不是非常方便。
为改进管钳,许多发明人进行了发明创造,并且申请了许多专利技术,如申请号为02259580的“一种管扳大力钳”,申请号为02220422的“管子钳”,均可为证。虽然设计各有巧妙之处,但便不是说就再不可能改变和变革了。
本实用新型的目的就是提供一种使夹紧和松开都变得轻松,使工作效率得到极大提高的杠杆式管钳。
三、发明内容
实现本实用新型的技术方案是这样的:由手柄6,钳口组成的管钳,手柄6为槽形,在头部开有圆孔,圆孔内装有半圆垫圈2,该半圆垫圈滑动套联于主钳杆1上,在主钳杆1上设有螺纹,并装置有锁紧螺母3,在主钳杆的头部设有钳口,在手柄6的头部用铆钉4联接有副钳口5。主钳杆1设置于手柄6的槽内。
本实用新型的有益效果在于:由于增加了手部夹持的加力杠杆,使夹紧和松开都变得轻松。实践证明,比现有管钳轻便灵活,不易打滑;手柄上的副钳口为圆周运动,不必准确调整钳口尺寸;单手即可操作,大大提高了工作效率,该管钳在外径为Φ10mm~Φ70mm的范围内是非常实用的。
四、附图说明
图1是本实用新型的整体结构示意图。
五、具体实施方式
下面结合附图对本实用新型的具体实施方式说明如下:
由手柄6,钳口组成的管钳,手柄6为槽形,在头部开有圆孔,圆孔内装有半圆垫圈2,该半圆垫圈滑动套联于主钳杆1上,在主钳杆1上设有螺纹,并装置有锁紧螺母3,在主钳杆的头部设有钳口,在手柄6的头部用铆钉4联接有副钳口5。主钳杆1设置于手柄6的槽内。
使用时转动销紧螺母3可调节钳口的开度和提供夹持力。由于主杆钳1可在半圆垫圈的支承下作圆周运动,用手握紧时还提供了杠杆力,从而实现了本实用新型的发明创造目的。
