Abstract

The utility model discloses a plastic wrapping column structure which comprises a hollow circular metal tube. A plastic outer shell with a square end face wraps the outside of the circular metal tube. The plastic outer shell is formed by clamping two U-shaped plastic sleeves which are completely the same in structure. The U-shaped plastic sleeves are formed in an integrated extrusion molding mode. Each U-shaped plastic sleeve comprises a long wall and two short walls which are vertically connected at two ends of the long wall and on the same side. A plug connector is arranged at one end of one short wall, and an inserted connection groove matched with the plug connector is arranged at one end of another short wall. The circular metal tube and the plastic outer shell outside the circular metal tube are matched with each other to form the wrapping column. On the basis that enough mechanical strength is provided, the extrusion formed plastic outer shell is adopted, so that the wrapping column is enabled to be low in the whole cost, and convenient to produce, machine, and install.
