The invention discloses a hydraulic jack good in stability. A hydraulic pump control switch is used for starting a hydraulic pump, the hydraulic pump is used for conveying oil in an oil storage tank into an oil cylinder through an oil pipe and a connecting pipe, the oil is used for upwards extruding a piston in the oil cylinder, and therefore a plunger on the piston is driven to move upwards to eject an upper vehicle up, and vehicle maintenance is facilitated. An electromagnetic valve control switch is used for controlling an electromagnetic valve on an oil return pipe to be opened, and the oil in the oil cylinder enters the oil storage tank from an oil return pipe. Due to the arrangement of four buffering devices, extruding force is generated downwards when the plunger ascends, the buffering devices are extruded downwards, and therefore an upper buffering plate and a buffering sleeve are driven to conduct downward extruding, a first buffering spring, a second buffering spring and a third buffering spring are extruded, upward buffering force is formed on the first buffering spring, the second buffering spring and the third buffering spring, vibration generated by work of the hydraulic pump and the plunger is conveniently relieved, the stable effect is good, wobbling is prevented, and the safety performance is high.

    本发明公开了一种稳定性好的液压千斤顶,通过液压泵控制开关启动液压泵,液压泵将储油箱内的油通过进油管、连接管运送到油缸内,油将油缸内的活塞向上挤压,从而带动活塞上的柱塞向上移动,将上方的车辆顶起,便于车辆的维修,通过电磁阀控制开关控制回油管上的电磁阀打开,油缸内的油从回油管进入到储油箱内,通过设置四个缓冲装置,柱塞上升时向下产生挤压力,对缓冲装置向下进行挤压,从而带动上缓冲板、缓冲套筒向下挤压,对第一缓冲弹簧、第二缓冲弹簧、第三缓冲弹簧进行挤压,第一缓冲弹簧、第二缓冲弹簧、第三缓冲弹簧形成一个向上的缓冲力,便于减缓液压泵、柱塞工作时产生的震动,稳定效果好,防止晃动,安全性能高。
