Abstract
The invention discloses a lifting lead screw. The lifting lead screw comprises a lead screw portion, wherein the lead screw portion is a cylinder; a thread is arranged on the peripheral surface of the lead screw portion; a first shaft end and a second shaft end are arranged at the two ends of the lead screw portion respectively; the widths or diameters of the first shaft end and the second shaft end are smaller than the diameter of the lead screw portion; the outer end of the second shaft end is connected with a disc portion; the disc portion and the second shaft end are coaxial. The lifting lead screw is simple in structure and can meet the requirement of driving objects to lift.
Description
Technical field
The present invention relates to a kind of elevating screw.
Background technology
Elevator is a kind of operating equipment for article lifting, uses screw mandrel sometimes in its structure.The rotation of screw mandrel can driven object up-down, and the screw mandrel of Rational structure is the important component part in jacking equipment.
Summary of the invention
