Title:
CONNECTION STRUCTURE OF EXTERNAL THREAD AND TRADITIONAL THREAD WITH ASYMMETRICAL BIDIRECTIONAL CONICAL THREAD HAVING OLIVE-LIKE SHAPE
Document Type and Number:
WIPO Patent Application WO/2019/192561
Kind Code:
A1
Abstract:
Disclosed is a connection structure of an external thread and a traditional thread with an asymmetrical bidirectional conical thread having an olive-like shape, solving problems such as the poor self-positioning and self-locking of existing threads. The external thread (9) is an olive-like shape (93) bidirectional truncated cone body (71) in an outer surface of a columnar matrix (3) 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 internal thread (6); and after assimilation, the internal thread (6) is a specialized conical hole (4) in an inner surface of a tubular matrix (2) in the form of a spiral, and the performance mainly depends on the circular conical surfaces and taper sizes of thread bodies. The advantage is achieved as follows: the internal and external threads form a series of circular conical pairs with the specialized conical hole (4) and the bidirectional truncated cone body (71) 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.
