Abstract

本实用新型涉及易更换的盘根,缩短更换时间。它是在环状盘根1的一侧平面制出孔槽2,可制出椭圆形孔槽。更换时,可在电工螺丝刀3的端头上制出钩子4,伸入孔槽再转动某一角度可诸个起出。

Description

易更换的盘根
本实用新型涉及一种易更换的盘根。
一般在上下(转动)杆的配合处都加装盘根,用以密封。在油田抽油机井抽油杆与井配合处用盘根密封,由于盘根数量多,而且安装紧,经磨损后要经常更换。目前,采用的是环状盘根,相互间夹的很紧,要把已磨损的盘根取下既费力又费时,更换盘根是一项艰苦的事情。
本实用新型的目的在于避免目前技术中存在的不足之处,而提供一种易更换的盘根,可缩短更换时间。
本实用新型的目的可以通过以下技术方案来达到:在环状盘根一侧上制有孔槽。更换时间用端头上带钩子螺丝刀伸入孔中,可勾出旧盘根。
在上述方案中,可采椭圆形孔槽,螺丝刀端头上钩子易伸入此孔,伸入后再动某一角度,可方便取出。
本实用新型与上述目前环状盘根相比较可具有如下优点:由于在每个环状盘根上形成孔槽,采用相应的工具易诸个勾出更换的旧盘根,省时省力,提高工作效率。
附图1、2是本实用新型的主、俯视图;
附国3、4是图1、2上环状盘根采用的工具主、左视图。
下面结合附图将对本实用新型作进一步的说明:
由附图1、2所示,在环状盘根1一侧平面上制出孔槽2。更换旧盘根时,可采用电工螺丝刀3,在该刀子端头制出向上钩子4,用此工具伸入孔槽2,可诸个勾出。
在上述方案中,可采用椭圆形孔槽2,不用制成透槽。椭圆形孔槽易使头端带钩子4的螺丝刀插入,而后再转动某一角度,可勾出更换的旧盘根。

Claims (2)

1、一种易更换的盘根,是在环状盘根(1)上构成的,其特征在于:在环状盘根(1)的一侧上制孔槽(2)
2、根据权利要求1所述的盘根,其特征在于:可采用椭圆形孔槽(2)。
