Abstract
The utility model provides a 90-degree bend rapidly-locked two-dimensional hinge joint assembling component. A main body of the 90-degree bend rapidly-locked two-dimensional hinge joint assembling component is composed of a pair of bend hinge joint blocks, wherein the side edges of the bend hinge joint blocks are provided with cross meshed hinge teeth which are bent by 90 degrees. An upper conic through hole and a lower conic through hole are formed between the meshed hinge teeth symmetrically, an upper conic sleeve shaft and a lower conic sleeve shaft are matched with the interiors of the conic through holes, a flat bottom head cap screw penetrates through the conic sleeve shafts, one end of the flat bottom head cap screw is connected with a fork wrench, the other end of the flat bottom head cap screw is connected with the lower conic sleeve shaft, and the position, close to the lower side of the handle, of the fork wrench is provided with an eccentric protrusion. Through the structure, the fork wrench is pressed down so that the hinge joint assembling component can be locked rapidly. The side edges of the left bend hinge joint block and the right bend hinge joint block are respectively provided with an end so that two metal tubes can be connected. The 90-degree bend rapidly-locked two-dimensional hinge joint assembling component has the advantages that the conic sleeve shafts can generate large static friction force in the axial direction and the radial direction at the same time, and the left bend hinge joint block and the right bend hinge joint block which are bent by 90 degrees enable the connected metal tubes to be positioned at the included angle ranging from 0 degree to 180 degrees.
