The invention relates to the technical field of mechanical equipment, and discloses a jack with an anti-toppling structure. The jack comprises a base. First rotating shafts are movably mounted on thetwo sides of the base. The outer sides of the first rotating shafts are movably sleeved with bottom arm rods. According to the jack with the anti-toppling structure, through the combined use of a first hydraulic rod, a second hydraulic rod, a rotating shaft, the bottom arm rods and an upper arm rod, the bottom arm rods and the upper arm rod can be well supported by the structure of the first hydraulic rod and the rotating shaft after the height of the equipment is adjusted, so that a screw rod does not provide stretching resistance bearing effect; and the first hydraulic rod is communicated with the second hydraulic rod through oil pipes, so that when the first hydraulic rod performs bearing, hydraulic oil is discharged into an inner back shore of the second hydraulic rod, the local pressure value borne by the first hydraulic rod reacts on second hydraulic rod liquid, and a certain support force in the transverse direction is provided. The device can achieve the synergic effect of longitudinal and inclined support, and the stability of the device is guaranteed.

    本发明涉及机械设备技术领域,且公开了一种具有防倾倒结构的千斤顶,包括底座,所述底座的两侧活动安装有第一转轴,所述第一转轴的外侧活动套装有底部臂杆。本发明通过设有第一压杆液、第二液压杆、转动轴、底部臂杆和上臂杆的组合使用,该装置能够在设备调整高度后使得第一液压杆、转动轴的组织结构对底部臂杆和上臂杆起到较好的支撑作用,且可使丝杆不提供抗拉力承载效果,通过将第一液压杆与连第二液压杆采用油管连通,使得第一液压杆在承载时,将液压油排入第二液压杆的内部顶撑,将第一压杆液受到的局部压力值反作用于第二压杆液,使其横向具有一定的支撑力,该装置能够达到纵向与斜向支撑的协同效果,保障其稳定性。
