<p>A pipe element fast connection structure is disclosed, in which an inner pipe element (3) is inserted in an outer pipe element (6) and two pipe elements are fixed each other; the connection element comprises a sleeve pipe (1) and an annular spring element (2) with an open end, and the open end of the spring element (2) bends inward and forms a pair of plug (5); the sleeve pipe (1) is provided fixedly around the up end of the inner pipe element (3), and both of the inner pipe element (3) and the sleeve pipe (1) are inserted in the outer pipe (6); a pair of through holes (4) are provided on the outer pipe (6), and at least a concave groove is provided on the side wall of the sleeve pipe (5), corresponding to the through holes (4); the pair of plugs (5) of the spring element (2) plug into a pair of through holes (4) of the outer pipe (6), and when the spring element (2) is turned around the through holes (4) of the outer pipe (6), at least two steady state which form two working positions can be formed: a locking working position and an unlocking working position. The combined structure of the sleeve pipe (1) and the spring element (2) of the invention realize the fast locking and fast disassemble between pipes, and the structure is convenience, safe and reliable in use.</p> |
