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

[0027] Such as Figure 1 As shown, a convenient and stable thread structure, which is applied to the complete threaded part of external thread and internal thread, includes external thread 1, internal thread 7 and thread 2, thread 3, thread 4, thread 5, and thread 6. The thread height of thread 2 is slightly smaller than that of thread 3, the thread height of thread 3 is slightly smaller than that of thread 4, the thread height of thread 4 is slightly smaller than that of thread 5, and the thread height of thread 5 is equal to that of thread 6 . At the same time, the tooth profiles of thread 2, thread 3, thread 4, thread 5, and thread 6 can respectively adopt any tooth profile and tooth thickness. Thread 2, thread 3, thread 4, thread 5 are variable pitch threads, and thread 6 is equal pitch threads. The problem of rotation progress caused by different tooth thickness and tooth type is solved by the difference of variable pitch thread and tooth number.

Embodiment 2

[0030] Such as Figure II As shown, a convenient and stable thread structure, which 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 tooth of internal thread 1 is slightly greater than the tooth height of internal thread 2, and the tooth height of the tooth of external thread 4 is slightly greater than external thread 3. Its internal thread is integrally mated with the teeth of the complete thread on the external thread. Internal thread 1, internal thread 2, external thread 3, the profile of profile of external thread 4 can adopt the profile of the thread of common mineral water, beverage bottle cap.

[0031] When using, press the bottle cap into the mouth of the bottle, then rotate 90°~180° and tighten it.

Embodiment 3

[0033] Such as Figure three As shown, a convenient and stable thread structure, which is applied to the bottle caps of mineral water and beverages. It includes internal thread 1, internal thread 2, internal thread buckle 3 and external thread 4, external thread 5, external thread buckle 6. The tooth height of the tooth of internal thread 1 is slightly greater than the tooth height of internal thread 2, and the tooth height of the tooth of external thread 4 is slightly greater than external thread 3. Its internal thread is integrally mated with the teeth of the complete thread on the external thread. After the meshing is completed, the internal thread is engaged with the buckle on the external thread. Internal thread 1, internal thread 2, external thread 4, the profile of profile of external thread 5 can adopt the profile of the thread of common mineral water, beverage bottle cap.

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...
