Summary of the invention
The object of the present invention is to provide a kind of simple in structure, more piece screw elevator structure that productive costs is lower.
The object of the present invention is achieved like this:
More piece screw elevator structure of the present invention, comprise base, motor, transmission device, pipe box, screw rod, terminal pad, it is characterized in that: pipe box comprises driving pipe box and leading screw pipe box mechanism, motor, transmission device and driving pipe box are installed on the base, motor links to each other with transmission device, and transmission device links to each other with the driving pipe box, and leading screw pipe box mechanism is installed in driving tube and puts, screw rod is installed in the leading screw pipe box mechanism, the top captive joint dish of screw rod.
More piece screw elevator structure of the present invention can also comprise:
1, described leading screw pipe box mechanism is made up of two or more leading screw pipe boxes.
2, described base is that a left-right symmetric is installed positioning plate with the axis of screw rod, and the upper end of positioning plate links to each other with terminal pad.
Advantage of the present invention is: improved the rising height of the body of rod greatly, can regulate height continuously, reduced working accuracy than like product, and lifting is steady, speed is fast, strength and stiffness are good, and load-carrying capacity is bigger, and is simple in structure, set up conveniently operation and easy to maintenance.
