[0002] Worm gear screw lift, also known as QWL lift, is widely used in machinery, metallurgy, construction, water conservancy equipment and other industries. It has many functions such as lifting, lowering, pushing with the help of auxiliary parts, flipping and various height position adjustments. SWL worm gear screw lift is a basic lifting component with many advantages such as compact structure, small size, light weight, wide power source, no noise, easy installation, flexible use, multiple functions, multiple supporting forms, high reliability and long service life.

[0003] At present, in the actual application of worm gear screw lifts, the movable seat slides with the surface of the screw under the driving action of the screw, so as to achieve the height adjustment of the movable seat and the support thereon. However, since the screw is mostly directly exposed to the outside during the rotation drive process, the thread groove thereon is easy to accumulate dust particles. Over time, it is easy to cause wear and tear when the thread is matched with the movable seat, which easily reduces its service life. Therefore, we make improvements to this and propose a worm gear screw lift. Utility Model Content
