Title:
CONNECTION STRUCTURE OF INTERNAL THREAD AND TRADITIONAL THREAD WITH SYMMETRICAL BIDIRECTIONAL CONICAL THREAD HAVING OLIVE-LIKE SHAPE
Document Type and Number:
WIPO Patent Application WO/2019/192557
Kind Code:
A1
Abstract:
Disclosed is a connection structure of an internal thread and a traditional thread with a symmetrical bidirectional conical thread having an olive-like shape, the connection structure comprising an external thread (9) and an internal thread (6) in threaded fit with each other, wherein the internal thread (6) is an olive-like shape (93) 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) being the same and/or approximately the same as 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, and the performance mainly depends on the circular conical surfaces and taper sizes of thread bodies. The internal and external threads form a series of circular conical pairs with the bidirectional conical hole (41) and the specialized conical body (7) 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. Problems such as the poor self-positioning and self-locking of existing threads are solved.
