M285650 _#正. , 1 Case No. 94211 Logic __^月日3, Creation Description (1) [Technical field of new type] This creation is about a hub structure for pipe jointing, especially for point double fast positioning and The design of the two-circle pipe members can be designed to achieve the desired angle form or to save space, and the quick-locking position can be adjusted for the adjusted structure. That is, [previous technique] The conventional hub joint structure of the round pipe joint adopts a simple thread principle, but the thread lock is limited by the friction force, and the solid force is limited, if the two round pipe members are pivotally connected to each other. The friction coefficient caused by 'heavy, long-term wear and tear or the amount of uncertainty = strong, may cause looseness and affect the positioning of the structure and the safety of use. [New content]

Looking at the positioning stability of the conventional round pipe jointing structure: in the use of the pivotal pipe members that are connected to each other, the dangers that may occur when the J is rotated are often formed. And the creation of the moon: the main purpose is to improve the traditional pivot joints: "The stability of the position, in addition to the original angle of production: the stability of the overall structure has also been greatly improved. "It's just for this, for:: Another: the purpose is to improve the locking convenience of the traditional round pipe jointing structure, so that the locking action is more ingenious than the traditional round pipe joint two = 5 can In addition, the most specific refinement is that it provides the degree of phase, m, and m, and the degree of influence of the ^^^ on the structure and
