Abstract

本实用新型公开了一种防油缸活塞松脱装置,包括活塞和活塞杆,活塞套装在活塞杆的头端,活塞上设有密封件;其要点是所述活塞杆的头端由内到外依次呈两阶缩径结构,两阶缩径结构上分别设有右旋螺母和左旋螺母。本实用新型结构简单制作方便,由于活塞杆的头端呈两阶缩径结构,两阶缩径结构上分别设有右旋螺母和左旋螺母,将活塞牢牢紧固在活塞杆,解决了现有技术存在活塞易脱落的技术问题。

Description

一种防油缸活塞松脱装置
技术领域  本实用新型属于油缸活塞技术领域,涉及一种防油缸活塞松脱装置。
背景技术  现有技术的油缸活塞,包括活塞和活塞杆,活塞套装在活塞杆的头端。使用时,将活塞套在活塞杆上,用锁紧螺钉将活塞紧固,固定时,锁紧螺钉与活塞杆是点接触,接触面积小,只承受径向力,承力强度低,存在活塞易脱落的技术问题。
发明内容  本实用新型的目的是解决现有技术存在活塞易脱落的技术问题,提供一种防油缸活塞松脱装置,从而克服现有技术的不足。
为实现上述目的,本实用新型防油缸活塞松脱装置,包括活塞和活塞杆,活塞套装在活塞杆的头端,活塞上设有密封件;其要点是所述活塞杆的头端由内到外依次呈两阶缩径结构,两阶缩径结构上分别设有右旋螺母和左旋螺母。
本实用新型结构简单制作方便,由于活塞杆的头端呈两阶缩径结构,两阶缩径结构上分别设有右旋螺母和左旋螺母,两螺母受预紧力贴实,呈互相锁紧趋势,将活塞牢牢紧固在活塞杆,解决了现有技术存在活塞易脱落的技术问题。
附图说明  附图是本实用新型结构示意图。
具体实施方式  根据附图,本实用新型它包括活塞4和活塞杆5,活塞4套装在活塞杆5的头端,活塞4上设有密封件3;活塞杆5的头端由内到外依次呈两阶缩径结构,两阶缩径结构上分别设有右旋螺母2和左旋螺母1。
