Abstract

一种扳扣式磁卡销。主要解决现有锁销易从吊卡上脱落的问题。其特征在于:销杆(2)上端活动连接有矩形的锁环(1),销杆(2)下部镶嵌有磁环(3)。该扳扣式磁卡销具有不易从吊卡上脱落的特点。

Description

扳扣式磁卡销
技术领域:
本实用新型涉及油田钻井领域吊卡所用的锁销,尤其是扳扣式磁卡销。
背景技术:
在油田钻井领域,接钻杆时,需要用吊卡将钻杆吊起。吊卡吊钻杆时需要锁销将吊卡锁住。而现有吊卡锁销由于结构原因存在易从吊卡上脱落的问题,影响钻井安全。
实用新型内容:
为了解决现有锁销易从吊卡上脱落的问题。本实用新型提供一种扳扣式磁卡销。该扳扣式磁卡销具有不易从吊卡上脱落的特点。
本实用新型的技术方案是:该扳扣式磁卡销包括销杆以及锁环。销杆上端活动连接有矩形的锁环,销杆下部镶嵌有磁环。
本实用新型具有如下有益效果:该扳扣式磁卡销由于采用销杆上端活动连接有矩形的锁环,销杆下部镶嵌有磁环的结构。利用锁环卡套在吊卡上,再由磁环将锁环吸附在销杆,进而有效防止从吊卡上脱落现象产生,保证钻井安全性。所以说该扳扣式磁卡销具有不易从吊卡上脱落的特点。
附图说明:
附图1是本实用新型结构示意图。
图中1-锁环,2-销杆,3-磁环。
具体实施方式:
下面结合附图对本实用新型作进一步说明:
如图所示,该扳扣式磁卡销包括销杆2以及锁环1。销杆2上端活动连接有矩形的锁环1,销杆2下部镶嵌有磁环3,由矩形的锁环1向下套于吊卡上,再销杆2的磁环3吸附,因而有效防止从吊卡上脱落现象产生。
