Patent ID: 8069632

Claim:
An integrally assembled changeable framework connector used for a spatial structure, comprising: a) a framework, formed by an axial rod including a predetermined quantity of protruded connecting bases and a predetermined quantity of positioning elements at an intermediate position thereof, wherein the framework is in a predetermined shape and acts a main body of the whole connector; the protruded connecting base includes a base body having a ring body sleeved onto the framework, and a protruding body extended radially outward from a surface of the framework and having a plurality of levels provided for connections in different directions, and the protruding bodies including bodies in a same shape or different shapes; and b) at least two positioning elements, installed to upper and lower ends of the framework axially and respectively, such that the upper and lower ends of the framework constitute an axial coupling portion, and two upper and lower positioning elements fix the protruded connecting base onto the framework, and the three constitute a connector, and the axial coupling portion and radially extended protruding bodies of different directions, positions, and angles between corresponding connectors are assembled by axial pipes and lateral connecting elements to form a spatial structure in a predetermined shape.
