Abstract

一种涉及常规管材连接的多曲面自锁式管钳。 它由手柄3、钳头1和二者连接件2组成。其中手柄 3上钳口端为凸轮4,其上有多曲面板牙,凸轮与钳头 1用轴销2构成相互转动体,且钳头上有供凸轮转动 时通过的槽口5。本管钳随转动手柄使钳口愈来愈 小可卡牢物件,无打滑现象。

Description

一种用于油田常规管材接、卸的多曲面自锁式管钳。
管钳经使用一个时期后,由于钳牙有磨损出现打滑现象;根据管径不同要随时调节,有时经多次调节,这对于在寒冷季节操作人员来说,也不方便,影响工作效率。
本实用新型的目的在于避免上述现有技术中不足之处,而提供一种不需要调节钳口的多曲面自锁式管钳,随着转动手柄使夹持物愈来愈紧,无打滑现象。
本实用新型的目的可通过以下技术方案来达到:手柄上钳口端为多曲面板牙的凸轮,它与钳头用轴销构成相互转动体,且钳头上有供凸轮转动时通过的槽口。
本实用新型的目的还可以通过以下技术方案来达到:上述凸轮的轮廓为多曲面偏心形。
本实用新型相比现有技术具有如下效果:由于手柄上钳口端为多曲面偏心轮廓,其上有直径不一的带牙弧面,随着转动手柄钳口由大变小,使夹持物(管件)愈来愈紧,无打滑现象。
图1是本实用新型主视示图;
图2是图1上钳头部分俯视图。
由附图1、2所示,手柄3上钳口端加工或焊接凸轮4,其上有多曲面板牙,可与凸轮一体或易换接的;它与带板牙钳头1用轴销2构成相互转体,且钳头上有供凸轮转动时通过的槽口5;凸轮4的轮廓为多曲面偏心形。当管材置于钳口中时,通过转动手柄使钳口愈来愈小,可卡牢物件。本管钳可制成系列产品,以适应管径变化的需要。

Claims (2)

1、一种多曲面自锁式管钳,它由手柄3、钳头1和二者连接件2组成,其特征是:手柄3上钳口端为多曲牙面的凸轮4,它与钳头1用轴销2构成相互转动体,且钳头上有供凸轮转动时通过的槽口5。
2、如权利要求1所述的多曲面自锁式管钳,其特征是:凸轮4的轮廓为多曲面偏心形。
