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.

Embodiment 1

[0023] like Figure 1 As shown, a convenient and stable thread structure is applied to the complete thread part of the external thread and the internal thread, which includes external thread 1, internal thread 7 and thread 2, thread 3, thread 4, thread 5, thread 6. The thread height of thread 2 is slightly less than the thread height of thread 3, the thread height of thread 3 is slightly less than the thread height of thread 4, the thread height of thread 4 is slightly less than the thread height of thread 5, the thread height of thread 5 is equal to the thread height of thread 6 . At the same time, the thread 2, thread 3, thread 4, thread 5, and thread 6 can adopt any thread type and thread thickness respectively. Thread 2, thread 3, thread 4, thread 5 are variable pitch threads, and thread 6 is equal pitch thread. The problem of rotation progress caused by different tooth thickness and tooth shape is solved by the difference of variable pitch thread and number of teeth.

Embodiment 2

[0026] like Figure II As shown, a convenient and stable thread structure is applied to the bottle caps of mineral water and beverages. It includes internal thread 1, internal thread 2 and external thread 3, external thread 4. The tooth height of the internal thread 1 is slightly larger than that of the internal thread 2, and the tooth height of the external thread 4 is slightly larger than that of the external thread 3. Its internal thread is integrally matched with the teeth of the complete thread on the external thread. The tooth shape of the inner thread 1, the inner thread 2, the outer thread 3, and the outer thread 4 can be the thread shape of the ordinary mineral water and beverage bottle caps.

[0027] When using, press the bottle cap into the bottle mouth, and then rotate 90°~180° to tighten.

Embodiment 3

[0029] like Figure 3 As shown, a convenient and stable thread structure is applied to the bottle caps of mineral water and beverages. It includes internal thread 1, internal thread 2, internal thread snap 3 and external thread 4, external thread 5, and external thread snap 6. The tooth height of the internal thread 1 is slightly larger than that of the internal thread 2, and the tooth height of the external thread 4 is slightly larger than that of the external thread 3. Its internal thread is integrally matched with the teeth of the complete thread on the external thread. After the meshing is completed, the inner thread is locked with the buckle on the outer thread. The tooth shape of the inner thread 1, the inner thread 2, the outer thread 4, and the outer thread 5 can be the thread shape of the ordinary mineral water and beverage bottle caps.

[0030] When in use, press the bottle cap into the bottle mouth, then rotate 90°~180° to tighten, and at the same time make the b...

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 thread refers to a helical continuous convex part with a specific cross-section made on the surface of a cylindrical or conical base. The traditional thread needs to rotate many times during engagement, which takes a long time, and because of the traditional Threads are usually equal-pitch threads. When the thread is subjected to an axial load, the force on the thread is uneven, which is very unfavorable for the stability of the threaded connection. In some occasions that require rapid meshing or are required 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. Using traditional threads no...
