Abstract

本实用新型的目的是要提供一种改进了的自复 位液压千斤顶,它可以有效地节省人力和时间。
本实用新型的目的是这样达到的:在液压千斤顶 的顶壁和顶杆之间加一只弹簧,使用时,顶杆上升,弹 簧被压缩。当用完后,只需打开油路阀门,在弹簧的 作用下,顶杆便会被压回。从而节省了人力和时间。
本实用新型因只需在液压千斤顶的顶壁和顶杆 之间加一只弹簧,所以结构特别简单和容易实现。

Description

本实用新型涉及一种起重工具,特别是液压千斤顶。
液压千斤顶在使用完毕后,需打开油路阀门,然后用人力踩回伸出的顶杆。这样做一方面费力;一方面浪费时间。
本实用新型的目的是要提供一种改进了的自复位液压千斤顶,它可以有效地节省人力和时间。
本实用新型的目的是这样实现的:在液压千斤顶的顶壁和顶杆之间加一只弹簧,当使用中,顶杆上升时,弹簧即被压缩。当用完后,只需将油路阀门打开,在弹簧的作用下,顶杆便会被压回。从而节省了人力和时间。
本实用新型只需在液压千斤顶的顶壁和顶杆之间加一只弹簧,所以结构特别简单和容易实现。
本实用新型的具体结构由其附图给出。

Claims (2)

1、起重工具,特别是液压千斤顶,其特征是在顶壁和顶杆之间有一只弹簧,当油路阀门打开时,即对顶杆产生作用力,使其退回。
2、根据权利要求1所述的千斤顶,其特征是顶壁和顶杆有一只弹簧。
