The scissor rod lifting platform comprises a base, a lifting platform body and a scissor lifting assembly connected between the base and the lifting platform body, the scissor lifting assembly comprises a first X-shaped movable frame, a second X-shaped movable frame and a driving rod, the middles of the first X-shaped movable frame and the second X-shaped movable frame are hinged, and a mounting transverse frame is arranged on the lower side of each X-shaped movable frame; the upper end and the lower end of the driving rod are rotationally connected with the bottom of the lifting table and the mounting transverse frame correspondingly, a jacking transverse frame located above the mounting transverse frame is arranged on the upper side of the second X-shaped movable frame, an arc-shaped block is arranged on the lower side face of the jacking transverse frame, and a crank rod is arranged in the middle of the mounting transverse frame. According to the lifting platform, a lever pushing structure is additionally arranged, and conversion of pushing force when the lifting platform is in a low position is achieved through the rocker arm, so that the lifting platform can descend to a position low enough during descending, the application range of the lifting platform is widened, and the service life of the lifting platform is prolonged.

    本发明公开了一种剪刀杆升降台,包括底座、升降台以及连接于底座与升降台之间的剪刀升降组件,剪刀升降组件包括中部铰接连接的X型活动架一和X型活动架二以及一驱动杆,X型活动架的下侧设置有一安装横架,驱动杆的上下两端分别与升降台底部以及安装横架可转动连接,X型活动架二的上侧设置有一位于安装横架上方位置的顶升横架,顶升横架的下侧面设置有一弧形块,安装横架中部设置有一曲柄杆,曲柄杆的中部通过转轴转动连接于安装横架上,曲柄杆的下端与驱动杆转动连接,本发明通过增设杠杆推动结构,通过摇臂实现升降台低处时的推力的转换,使得升降台在下降时能够下降至足够低位置,提高升降台适用范围以及使用寿命。
