Abstract

一种整杆固定式扶正器。主要解决现有插接式扶正器易脱落的问题。其特征在于:在抽油杆(1)接箍附近固化有内带钢骨架(2)的尼龙扶正体(3),扶正体(3)外均布有4个凸棱(4)。该整杆固定式扶正器具有固定性好、不易脱落的特点。

Description

整杆固定式扶正器
技术领域:
本实用新型涉及油田采油领域中抽油杆上所用的扶正器,尤其是整杆固定式扶正器。
背景技术:
在油田采油过程中,抽油机采油在油田普遍应用,为了防止抽油杆与油管偏磨,通常在抽油杆上加装扶正器,而目前的扶正器有多种,为了便于安装,常用相互插接的分体式扶正器,由于扶正器后插接在抽油杆的,在使用过程中受磨损后易脱落。
实用新型内容:
为了克服现有插接式扶正器易脱落的不足,本实用新型提供一种整杆固定式扶正器,该整杆固定式扶正器具有固定性好、不易脱落的特点。
本实用新型的技术方案是:该整杆固定式扶正器包包括抽油杆,在抽油杆接箍附近固化内带有钢骨架的尼龙扶正体,扶正体外均布有4个凸棱。
上述的钢骨架为半圆形。
本实用新型具有如下有益效果:该整杆固定式扶正器由于采取上述方案,在尼龙扶正体内加有钢骨架,增加了扶正器的强度,而且扶正器与抽油杆固化成一体,加强扶正器坚固性和抱紧力,解决了扶正器窜位的问题,从而起到了防脱落的目的,还有效的保护了接箍不被磨损。
附图说明:
附图1是本实用新型的结构剖视图。
图中1-抽油杆,2-钢骨架,3-扶正体,4-凸棱。
具体实施方式:
下面结合附图对本实用新型作进一步说明:
由图1所示,该整杆固定式扶正器包括抽油杆1,在抽油杆1接箍附近固化尼龙扶正体3,扶正体3内带有钢骨架2,钢骨架2为半圆形。扶正体3外均布有4个凸棱4。在尼龙扶正体3内加有钢骨架2,增加了扶正器的强度,而且扶正体与抽油杆1固化成一体,加强扶正器坚固性和抱紧力,解决了扶正器窜位的问题,从而起到了防脱落的目的,还有效的保护了接箍不被磨损。
