The invention provides a lifting stand column with a small installation distance. The lifting stand column comprises a driving device, a lifting pipe and a transmission assembly. The lifting pipe comprises a first pipe, a second pipe, a third pipe, a fourth pipe and a fifth pipe. The lower end of the fifth pipe is fixed to the driving device. The transmission assembly comprises a first screw rod,a second screw rod, a third screw rod and a fourth screw rod. The output end of the driving device is in transmission fit with the first screw rod and can drive the first screw rod to rotate. The lower end of the second screw rod is provided with a first nut in threaded transmission connection with the first screw rod. The lower end of the third screw rod is provided with a second nut in threadedtransmission connection with the second screw rod. The lower end of the fourth screw rod is provided with a third nut in threaded transmission connection with the third screw rod. The lower end of thefirst pipe is provided with a fourth nut in threaded transmission connection with the fourth screw rod. The adjacent screw rods are in threaded transmission connection, in addition, each nut is located between the corresponding two adjacent screw rods, the transmission assembly can be more compact in the axial direction and the radial direction, and the small installation distance and the large stroke of the lifting stand column are achieved.
本发明提供一种低安装距的升降立柱,包括驱动装置、升降管及传动总成,升降管包括第一管、第二管、第三管、第四管和第五管,第五管的下端固定于驱动装置上,传动总成包括第一丝杆、第二丝杆、第三丝杆和第四丝杆,驱动装置的输出端与第一丝杆传动配合且可驱动第一丝杆旋转,第二丝杆的下端设有与第一丝杆螺纹传动连接的第一螺母,第三丝杆的下端设有与第二丝杆螺纹传动连接的第二螺母,第四丝杆的下端设有与第三丝杆螺纹传动连接的第三螺母,第一管的下端设有与第四丝杆螺纹传动连接的第四螺母,相邻丝杆通过螺纹传动连接,且螺母位于相邻两个丝杆之间,使得传动总成的轴向和径向都更加紧凑,实现升降立柱的低安装距大行程。
