The invention relates to the technical field of automobile maintenance equipment, and discloses a jack capable of improving lifting stability and lifting height. The jack comprises a frame body; a screw rod is rotatably connected to the middle part of the frame body; a rocker is fixedly connected to the right end of the screw rod; a fixed block is connected to the left end of the screw rod in a limiting manner; supporting rods are hinged to the upper end and the lower end of the fixed block; a lifting rod set is hinged to the middle of the frame body; and a first protruding block is fixedly connected to the left end of the lifting rod set. According to the jack capable of improving the lifting stability and the lifting height, a blocking frame is made to move towards one side of a chassisthrough rotation of a cam; a structure connected to the blocking frame provides clamping force, so that the effect of preventing a vehicle base from sideslip is achieved; the safety of equipment is improved; the lifting rod set is unfolded upwards, and the lifting height is increased through the structure of the lifting rod set; meanwhile, the supporting rods are unfolded to share gravity borne bythe lifting equipment, so that the effect of increasing the lifting height is achieved; and the equipment stability is improved.
本发明涉及汽车维修设备技术领域,且公开了一种提高举升稳定性和举升高度的千斤顶,包括架体,所述架体的中部转动连接有螺旋杆,所述螺旋杆的右端固定连接有摇杆,所述螺旋杆的左端限位连接有固定块,所述固定块的上下两端铰接有支杆,所述架体的中部铰接有举升杆组,所述举升杆组的左端固定连接有凸块一。该提高举升稳定性和举升高度的千斤顶,通过凸轮的旋转使挡架向底盘一侧移动,挡架上所连结构提供夹紧的力度,达到防止车底座发生侧滑的效果,提高设备的安全性,通过举升杆组向上展开,举升杆组的结构增加了抬升高度,同时支杆展开分担举升设备承受的重力,达到增加抬升高度的效果,增加了设备稳定性。
