The invention relates to a multifunctional jack which is composed of protective rubber, n belleville springs, a buffer cover, a jack rod, a transmission nut, a nut anti-retreating cover and a jack base. The n belleville springs are installed between the jack rod and the buffering cover in a series connection mode, and the deformation buffering function, the stress locking function, the flexible supporting function and the damping and anti-loosening function between the jack and a load are achieved. The buffer cover is screwed into the jack rod through threads and pressed on the belleville springs, and the installation mode of the n belleville springs is kept. The transmission nut is screwed into the jack rod in a threaded mode and placed on the jack base, and the jack function is achieved through threaded transmission. The nut anti-retreating cover is clamped in a limiting groove of the jack base and connected to the transmission nut through a screw, and the upward freedom degree of the jack rod is limited. A screw is screwed into the jack base and inserted into the jack rod guide groove to limit the rotational degree of freedom of the jack rod; the protection rubber sheet is pasted on the upper surface of the buffer cover and the lower surface of the jack base and used for achieving the contact surface protection function.
本发明涉及一种多功能千斤顶,由保护胶皮、n个蝶形弹簧、缓冲罩、千斤顶杆、传动螺母、螺母防退盖和千斤底座组成。n个蝶形弹簧按照串联方式安装在千斤顶杆和缓冲罩之间,实现千斤顶与负载之间的变形缓冲功能、应力锁紧功能、柔性支撑功能和减震防松功能;缓冲罩通过螺纹旋入千斤顶杆,压在蝶形弹簧上,保持n个蝶形弹簧的安装方式;传动螺母螺纹旋入千斤顶杆,放置在千斤底座上,通过螺纹传动实现千斤顶功能;螺母防退盖卡在千斤底座限位槽里通过螺钉连接在传动螺母上,限制千斤顶杆向上的自由度;采用螺钉旋入千斤底座插入千斤顶杆导向槽限制千斤顶杆旋转自由度;保护胶皮粘贴在缓冲罩上表面和千斤底座的下表面,用于实现接触面保护功能。
