The invention relates to a light lead screw lifting mechanism which comprises a lifting bucket module, a driving module, a lead screw module and a connecting module. The lifting bucket module comprises n lifting buckets. The driving module comprises a motor, a transmission gear I and a transmission gear II. The lead screw module comprises n lead screws; the first end of the lead screw on the innerside stretches outward from the first end of the adjacent lead screw on the outer side; except the innermost lead screw, the first ends of the rest of lead screws are provided with lead screw nuts; aguide nut is mounted at the tail end of each lead screw; and the first end of the innermost lead screw is connected to the transmission gear II; the connecting module comprises n connecting plates; except the connecting plate in the innermost lifting bucket, bearings are mounted on the connecting plates in the rest of lifting buckets; the connecting plate in the outermost lifting bucket is connected to the lead screw nut on the outermost lead screw; and except the lead screw nut on the outermost lead screw, the rest of lead screw nuts are assembled in the bearings successively. The light leadscrew lifting mechanism has the characteristics of being small in size, light in weight, large in stroke, stable and reliable to operate and the like.

    本发明涉及一种轻型丝杆升降机构,包括升降桶模块、驱动模块、丝杆模块和连接模块。升降桶模块包括n个升降桶。驱动模块包括电机、传动齿轮一和传动齿轮二。丝杆模块包括n节丝杆;位于内侧的丝杆首端从与之相邻的位于外侧的丝杆的首端向外伸出;除最内侧丝杆外,其余丝杆首端均设有一丝杆螺母;每节丝杆的末端安装有一导向螺母;最内侧丝杆首端与传动齿轮二相连。连接模块包括n块连接板;除最内侧升降桶中的连接板外,其余升降桶中的连接板上均安装有轴承;最外侧升降桶内的连接板与最外侧丝杆上的丝杆螺母相连;除最外侧丝杆上的丝杆螺母外,其余丝杆螺母依次装配在各轴承中。本发明具有尺寸小、重量轻、行程大、运行稳定可靠等特点。
