Title:
CONNECTION STRUCTURE OF INTERNAL THREAD AND TRADITIONAL THREAD WITH ASYMMETRICAL BIDIRECTIONAL CONICAL THREAD HAVING DUMBBELL-LIKE SHAPE
Document Type and Number:
WIPO Patent Application WO/2019/192576
Kind Code:
A9
Abstract:
Disclosed is a connection structure of an internal thread and a traditional thread with an asymmetrical bidirectional conical thread having a dumbbell-like shape. The internal thread (6) is a dumbbell-like shape (94) bidirectional conical hole (41) in an inner surface of a tubular matrix (2) in the form of a spiral, has a complete unit thread with a left-side taper (95) larger than and/or smaller than a right-side taper (96), and has the ability to assimilate the traditional external thread (9); and after assimilation, the external thread (9) is a specialized conical body (7) in an outer surface of a columnar matrix (3) in the form of a spiral. The internal and external threads form a series of circular conical pairs with the bidirectional conical hole and the specialized conical body by means of a cone hole containing a cone to form a thread pair (10) until the circular conical surfaces of inner and outer circular cones in the form of spirals are in sizing cooperation or sizing interference to realize a thread connection function, thereby improving the self-positioning ability and self-locking of threads.
