The present invention is directed to a joint (10) of a supporting frame, which includes a basic unit (12) to connecting with one to six connecting units (11) at a related side plate (111). The connecting unit (11) can connect with related crossbeams (20) to assembling a supporting frame; wherein each connecting unit has provided with a folded elastic plate (112) at both ends with a related groove (113) therebetween to engage with an end of the crossbeam (20). The basic unit (12) is cubic and has one side opening, which can be sealed by a door (13) to form a complete cubic hollow unit. By use of the basic unit engaging with desired connecting units, it provides the joints with various configurations, which can be used at any position in a supporting frame. <IMAGE> |
