The invention discloses a dual-ball lead screw lifting mechanism. The dual-ball lead screw lifting mechanism comprises a connecting assembly, a first ball lead screw assembly, a second ball lead screwassembly and a base, wherein the connecting assembly comprises a lifting base and a first rotary shaft; the first rotary shaft is rotatably connected to the lifting base; a rotary driver is arrangedon the lifting base; the first ball lead screw assembly comprises a first lead screw and a first ball nut; the first rotary shaft sleeves outside the first lead screw; the second ball lead screw assembly comprises a second lead screw and a second ball nut; the second lead screw and the first lead screw are reverse in rotation directions; the second lead screw sleeves outside the first lead screw;a second tube body is fixedly arranged on the second ball nut; the second tube body sleeves outside the second lead screw; and the first lead screw is fixedly arranged on the base or one of the secondtube body and the second lead screw is fixedly arranged on the base. While the rotary driver drives the first rotary shaft to rotate, the first lead screw and an external connector can get away fromthe lifting base or get close to the lifting base simultaneously; and a lifting platform is arranged on one of the first lead screw and the external connector, and the other one is fixedly arranged onthe base, so that the lifting stroke of the lifting platform is greater.

    本发明公开了一种双滚珠丝杠升降机构,包括:连接组件,包括升降座和第一转轴,第一转轴与升降座转动连接,升降座上设有旋转驱动器;第一滚珠丝杠组件,包括第一丝杆和第一滚珠螺母,第一转轴套于第一丝杆外侧;第二滚珠丝杠组件,包括第二丝杆和第二滚珠螺母,第二丝杆与第一丝杆旋向相反,第二丝杆套于第一丝杆外侧,第二滚珠螺母上固设有第二管体,第二管体套于第二丝杆外侧;底座,第一丝杆固设于底座上或第二管体和第二丝杆其中之一固设于底座上。旋转驱动器驱动第一转轴转动时,第一丝杆和外连接件能同时远离或同时靠近升降座;把升降平台设置在第一丝杆和外连接件其中之一上,另一固定设置在底座上,则升降平台的升降行程较大。
