Abstract
The invention discloses a screw thread fastening component, which comprises a body, wherein external screw threads are arranged on the body; the screw pitch radius of the external screw threads is smaller than or equal to the engaging length of internal screw threads engaged with the external screw threads. Through the arrangement of the external screw threads of the screw thread fastening component, the engagement of the screw thread fastening element and the internal screw threads is tighter.
Description
Technical field
The present invention relates to a kind of screw threads for fastening component, specifically, relate to a kind of externally threaded screw threads for fastening component having and engaging better effects if with female thread.
Background technology
Refer to the screw threads for fastening component schematic diagram that Fig. 1-2, Fig. 1 are prior art, Fig. 2 is the partial enlarged drawing of Z in Fig. 1.As shown in Figure 1-2, the screw threads for fastening component in Fig. 1-2 is plug screw, comprises body 111 and brim part 112；Body 11 is provided with external screw thread 1111；O 12 is sheathed on body 111；Body 111 is threadedly connected to the screwed hole of body 13, and body 13 is provided with female thread 131.When plug screw is tightened against the screwed hole of body 13, owing to effective length of action of threaded portion is short, ridge polishes gradually, cause that plug screw easily gets loose, female thread 131 and external screw thread 1111 are one flank gearing simultaneously, so external force etc. are once make plug screw get loose, plug screw will be threaded off.Therefore develop a kind of screw threads for fastening component overcoming drawbacks described above and become a urgent problem.
Summary of the invention
The technical problem to be solved is in that 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, the difference of the middle line of described externally threaded middle line and described female thread is be more than or equal to the 5% of described externally threaded pitch radius and less than the 10% of described externally threaded pitch radius.
Above-mentioned screw threads for fastening component, wherein, the difference of the middle line of described externally threaded middle line and described female thread be more than or equal to the pitch radius of described female thread 5% and pitch radius less than described female thread 10%.
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.
The screw threads for fastening component of the present invention is directed to its effect of prior art and is in that, by arranging the external screw thread of the screw threads for fastening component of the present invention so that screw threads for fastening component fastens more with engaging of female thread.

Detailed description of the invention
Hereby detailed content for the present invention and technology illustrate, are now described further with a preferred embodiment, but are not necessarily to be construed as restriction of the invention process.
Refer to Fig. 3-5, Fig. 3 is screw threads for fastening element structure schematic diagram of the present invention；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, the screw threads for fastening component of the present invention is for plug screw, and this plug screw threaded is body, but the present invention is not limited thereto, and the component being such as screwed all can use the helicitic texture of the present invention.The body 211 of screw threads for fastening component, brim part 212 and annular element 22；Body 211 is provided with external screw thread 2111；Brim part 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 and female thread 231 are engaged.
Further, the difference △ R of the middle line N of the middle line W of external screw thread 2111 and female thread 231 be 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 be 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 very big resistance such that it is able to prevent from getting loose.
Above are only presently preferred embodiments of the present invention; not it is used for limiting scope of the invention process; when without departing substantially from present invention spirit and essence thereof; those of ordinary skill in the art are when can make various corresponding change and deformation according to the present invention, but these change accordingly and deformation all should belong to the scope of the claims appended by the present invention.
