Convenient and stable thread structure

Abstract

A convenient and stable thread structure comprises an inner thread and an outer thread, wherein heights of thread lines of complete threads on the outer thread are decreased progressively as a whole from one end to the other end of the thread structure, and the inner thread of the thread structure is paired with the outer thread as a whole. Heights of one or more portions of the thread lines of the complete threads on the outer thread can be equal and can be decreased progressively. The thread lines of the complete threads on the outer thread can be divided into one or more portions, and all portions of the thread lines can adopt any thread profile respectively and simultaneously. The thread lines of the complete threads on the outer thread can be divided into one or more portions, and all portions of the thread lines can adopt any thread thickness respectively and simultaneously. One or more buckles are arranged at one end of the inner thread, one or more buckles are arranged at the other end of the outer thread, and the buckles on the inner thread and the outer thread of the thread structure are clamped mutually after the inner thread is meshed with the outer thread. One or more portions of the complete threads on the outer thread can be uniform pitch threads and varying pitch threads. The thread structure has the advantages that the meshing time is short, the axial bearing capacity is high, the good effect can be achieved through the threads, the good torsion-resisting effect is achieved, and the thread structure is stable.

Description

technical field [0001] The invention relates to a thread structure, in particular to a convenient and stable thread structure. Background technique [0002] The traditional screw thread refers to a helical continuous convex part with a specific cross-section made on the surface of a cylindrical or conical parent body. The traditional screw thread needs to rotate many times when engaging, which takes a long time, and because of the traditional The threads are usually equal-pitch threads. When the threads are subjected to axial loads, the force on the threads is uneven, which is very detrimental to the stability of the threaded connection. In some occasions that require fast meshing or require the ability to withstand a certain axial force , or some commonly used parts in daily life waste a lot of manpower and material resources in the assembly process. Such as: mineral water bottle caps, beverage bottle caps, assembly of pens and other daily necessities, furniture, etc. T...

AI Technical Summary

Problems solved by technology

The use of traditional threads not only takes a long time to engage, but also has weak ability to bear axial force and is unstable at the same time

However, there is no thread structure that can replace the traditional thread that can quickly engage, withstand a certain axial force, and be stable.
