Abstract
The utility model provides an embedded nut which comprises an inner thread hole and a cylindrical periphery, and also comprises a first arc surface and a first plane, wherein the first arc surface extends radially from the cylindrical periphery and the first plane is connected with the beginning and the end of the first arc surface, and the cylindrical periphery and the arc surface are both provided with circumferentially distributed spline teeth. Compared with the traditional embedded nut singly using the spline teeth, the embedded nut has higher connecting strength. The utility model also provides a plastic member with the embedded nut.
Description
Technical field
The utility model relates to a kind of embedded nut and has the working of plastics of embedded nut.
Background technique
In product design process, we are handlebar plastic part and other products situation about linking together with screw usually, but situations such as existing plastic part intensity is lower, may rupture in the process of screw-driving, creep.In order to reach better fastening effect, the technician need inlay a metal nuts usually in plastic part, remedy the deficiency of the intensity of plastic part with the intensity of metallic article.
Traditional embedded nut comprises threaded interior hole and columniform periphery, and has spline tooth in columniform periphery, between nut and nonmetallic material, transmit torsion by spline tooth, when tightening screw, nut is difficult for circumferentially rotating, but this structure still can circumferentially be rotated when being subjected to bigger torsion under the situation that join strength is had relatively high expectations, and therefore needs a kind of fixing more firm embedded nut and the working of plastics that has this embedded nut.
The model utility content
The technical problems to be solved in the utility model is the technical problem that existing embedded nut can't carry strong torsion; Provide following technological scheme for solving described technical problem the utility model:
A kind of embedded nut, comprise interior threaded hole and cylindrical peripheral, also comprise by radially extended first arc surface of described cylindrical peripheral, and with first plane that described first arc surface is connected from beginning to end, be equipped with the spline tooth of circumferentially arranging on the described cylindrical peripheral and first arc surface.
Further, described cylindrical peripheral is provided with groove.
Further, the cross section of described spline tooth can be triangle, rectangle or half round post.
Further, be provided with from the inwardly radially extended annular boss of hole wall bottom the described interior threaded hole.
Further, between described first plane and cylindrical peripheral, also be connected with second plane.
For solving problems of the prior art, the utility model also provides following technological scheme:
A kind of embedded nut, comprise interior threaded hole and cylindrical peripheral, it is characterized in that: also comprise by the radially extended a plurality of arc surfaces of described cylindrical peripheral, and, be equipped with the spline tooth of circumferentially arranging on described cylindrical peripheral and a plurality of arc surface with a plurality of planes that described a plurality of arc surfaces connect in turn from beginning to end.
Further, described cylindrical peripheral is provided with groove.
Further, the cross section of described spline tooth can be triangle, rectangle or half round post.
Further, be provided with from the inwardly radially extended annular boss of hole wall bottom the described interior threaded hole.
For solving problems of the prior art, the utility model also provides a kind of working of plastics that has above-mentioned embedded nut.
Compared with prior art the utlity model has following technique effect: the embedded nut that the utility model provides comprises interior threaded hole and cylindrical peripheral, also comprise by radially extended first arc surface of described cylindrical peripheral, and first plane that is connected from beginning to end with described first arc surface, be equipped with the spline tooth of circumferentially arranging on described cylindrical peripheral and the arc surface, compare with the embedded nut of existing simple practical spline tooth and to have higher join strength, the utility model also provides a kind of working of plastics that has above-mentioned embedded nut.
