Abstract
The utility model a convenient and stable thread structure, which comprises an internal thread and an external thread, wherein heights of teeth of a complete thread on the external thread are decreased progressively as a whole from one end to the other end of the thread structure, but one or more than one part of the tooth heights of the complete thread on the external thread of the thread structure is equal in height, and the internal thread and the external thread of the thread structure are paired as a whole. The teeth of the complete thread on the external thread are divided into one or more than one part, and arbitrary thread tooth profiles are respectively and simultaneously adopted by the teeth of each part. The teeth of the complete thread on the external thread are divided into one or more part, and tooth thicknesses are respectively and simultaneously adopted by the teeth of each part. One or more than one buckle is arranged at one end of the internal thread, one or more than one buckle is arranged at the other end of the external thread, and the buckles on the internal thread and the external thread of the thread structure are clamped after the internal thread and the external thread are engaged. One or more than one part of the complete thread on the external thread can be a uniform pitch thread and a varying pitch thread. The thread structure has the advantages that the engagement time is short, the axial bearing capacity is high, the threads can be good in effect, the twisting resistance is good, and the thread structure is more stable.
Description
Technical field
The utility model relates to a kind of worm structure, is specifically related to a kind of convenient stable worm structure.
Background technique
Traditional screw thread refers to the spiral yarn shaped continuous convex portion with particular cross section of making on cylinder or circular cone parent surface, traditional screw thread need to rotate a lot of circles when meshing, will take a long time like this, and due to conventional threads equal pitch thread normally, when screw thread bears after thrust load, the stressed of screw thread is inhomogeneous, the stability that double thread connects is like this very unfavorable, at some, need engagement fast or requirement can bear the occasion of certain axial force, or some the conventional parts in daily life have been wasted a large amount of man power and materials in assembling process.As: assembling and other daily living articles, the furniture etc. of mineral water bottle cap, beverage bottle cap, pen.Adopt conventional threads not only engagement time long, and a little less than bearing the ability of axial force, the while is unstable.But now also do not have to substitute can meshing fast of conventional threads, can bear certain axial force again, simultaneously stable worm structure also.
Summary of the invention

The purpose of this utility model is achieved through the following technical solutions:
A convenient stable worm structure, is characterized in that: Ya Gaocongqi one end to the other end of the tooth of the complete thread on described outside thread tapers off on the whole, and the tooth of the complete thread on its internal thread and outside thread matches on the whole.The high deviation of tooth of the tooth by the complete thread on internal thread and outside thread, outside thread can directly insert in internal thread, then, according to the concrete condition of screw thread, rotates to an angle, and tightens and can complete engagement.
Complete thread Yi Chuhuo many places on outside thread are equal pitch thread and variable pitch screw.
The tooth of the complete thread on outside thread is divided into one or more parts, and the tooth of each part adopts respectively tooth form arbitrarily simultaneously.
The tooth of the complete thread on outside thread is divided into one or more parts, and the tooth of each part adopts respectively that tooth is thick arbitrarily simultaneously.
One end of internal thread is provided with one or more buckles, and the externally threaded the other end is also provided with one or more buckles, and after engagement, its internal thread blocks mutually with the buckle on outside thread.
The utility model has the advantage of:
1. the high deviation of tooth of the tooth by the complete thread on internal thread and outside thread, outside thread can directly insert in internal thread, and then according to the concrete condition of screw thread, rotating to an angle to tighten to complete engagement, and engagement time is short.
2. the utility model adopts different teeth thick simultaneously, has stronger axial ability to bear.
3. the tooth of the complete thread on outside thread of the present utility model is divided into one or more parts, and the tooth of each part adopts tooth form arbitrarily simultaneously, allows it in conjunction with the advantage of multiple tooth form, make screw thread have better effect.
4. the one end by internal thread is provided with one or more buckles, and the externally threaded the other end is also provided with one or more buckles, and after engagement, its internal thread blocks mutually with the buckle on outside thread.Reach torsion proof effect, make it more stable.
