Technical problem to be solved in the utility model is to provide a kind of screw threads for fastening component, comprises body, and external screw thread is arranged on described body, and wherein, described externally threaded pitch radius is less than or equal to the length of action of the female thread engaged with described external screw thread.
Above-mentioned screw threads for fastening component, wherein, described externally threaded pitch radius is different.
Above-mentioned screw threads for fastening component, wherein, described externally threaded middle line is more than or equal to the 5% of described externally threaded pitch radius and less than the 10% of described externally threaded pitch radius with the difference of the middle line of described female thread.
Above-mentioned screw threads for fastening component, wherein, the difference of the middle line of described externally threaded middle line and described female thread is more than or equal to the 5% of the pitch radius of described female thread and 10% of the pitch radius less than described female thread.
Above-mentioned screw threads for fastening component, wherein, described difference is different.
Above-mentioned screw threads for fastening component, wherein, described difference is that inverted cone is arranged vertically.
Above-mentioned screw threads for fastening component, wherein, comprises brim part, is arranged at one end of described body and is connected to described body, maximum near the described difference of described brim part.
Above-mentioned screw threads for fastening component, wherein, the externally threaded thread near described brim part all contacts with the groove of the described female thread of engagement.
Above-mentioned screw threads for fastening component, wherein, also comprises annular element, is sheathed on the junction of described brim part and described body.
Above-mentioned screw threads for fastening component, wherein, described annular element is elastomeric material.
Screw threads for fastening component of the present utility model is directed to its effect of prior art and is, by arranging the external screw thread of screw threads for fastening component of the present utility model so that screw threads for fastening component more fastens with engaging of female thread.

Detailed description of the invention
Hereby illustrate about detailed content of the present utility model and technology, be now described further with a preferred embodiment, but be not necessarily to be construed as the restriction that this utility model is implemented.
Refer to Fig. 3-5, Fig. 3 is this utility model screw threads for fastening element structure schematic diagram；Fig. 4 is the threaded schematic diagram of Fig. 3；Fig. 5 is the partial enlarged drawing of Y in Fig. 4.As in Figure 3-5, screw threads for fastening component of the present utility model as a example by plug screw, this plug screw threaded for body, but this utility model is not limited thereto, and the component being such as screwed all can use helicitic texture of the present utility model.The body 211 of screw threads for fastening component, brim part 212 and annular element 22；External screw thread 2111 it is provided with on body 211；Cap
Eaves portion 212 is connected to one end of body 211；Annular element 22 is elastomeric material, and is sheathed on the junction of brim part 212 and body 211；The pitch radius of external screw thread 2111 is less than or equal to the length of action engaged with female thread 231；The pitch radius of external screw thread 2111 is different；When body 211 is screwed into the screwed hole of body 13, external screw thread 2111 is engaged with female thread 231.
Further, the difference △ R of the middle line N of the middle line W of external screw thread 2111 and female thread 231 more than or equal to external screw thread 2111 pitch radius 5% and less than external screw thread 2111 pitch radius 10% or external screw thread 2111 middle line W and the middle line N of female thread 231 difference △ R more than or equal to the pitch radius of female thread 231 5% and pitch radius less than female thread 231 10%.
Yet further, difference △ R is different, and arranged vertically in inverted cone, maximum near the difference △ R of brim part 212.
Further, fit tightly as it is shown in figure 5, all contact with the groove 231 of female thread 231 of engagement near the thread 2112 of the external screw thread 2111 of brim part 212 at mouth so that thread 2112 is the effect of voussoir, get loose to plug screw cap and bring the biggest resistance such that it is able to prevent from getting loose.
Above are only preferred embodiment of the present utility model; not it is used for limiting the scope that this utility model is implemented; in the case of without departing substantially from this utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and deformation according to this utility model, but these change accordingly and deformation all should belong to the scope of the claims appended by this utility model.
