Full-thread screw with female hole square flange head

带母孔方凸缘头的全螺纹螺丝

Abstract

The utility model discloses a full-thread screw with a female hole square flange head. The full-thread screw comprises a screw body, wherein the screw body is provided with a rod part body and a tailend part body which are integrally molded, continuous external thread bodies with outwardly concave convex tooth space structures are radially manufactured at the head end of the rod part body, and the thread axial length of each external screw body is equal to the length of the rod part body; continuous internal thread bodies with inwardly concave convex tooth space female hole structures are axially manufactured at the tail end of the screw body, the length of each internal screw body is at least equal to that of the tail end part body, and the screw body is an eighth structure with a squareflange head shape; since inwardly concave thread holes are manufactured at the tail part, the structure is novel, and the manufacture is convenient; the apertures of the inwardly concave thread holesare moderate, a new rear output connection method is added when the performance of the original screw body is retained, and the structural strength of the original screw body is not affected; and therequirements of different connection methods can be further met by manufacturing the thread holes into threads with different specifications.
本实用新型公开了带母孔方凸缘头的全螺纹螺丝,包括螺丝本体,该螺丝本体具有一体成型的杆部体和尾端部体,杆部体头端径向制有连续的外凹凸齿槽结构的外螺纹体,并且该外螺纹体的螺纹轴向长度等于杆部体长度;螺丝本体尾端轴向制有连续的内凹凸齿槽母孔结构的内螺纹体,并且该内螺纹体的长度至少等于尾端部体的长度值,螺丝本体为方形凸椽头形状体的第八结构体;采用在尾部制有内凹的螺纹孔,其结构新颖,制作便捷;内凹的螺纹孔其孔径适中,在保持原螺丝体性能的同时,增加了新的后部输出连接方式,且也不会影响原螺丝体的结构强度;将该螺纹孔制成不同规格的螺纹方式,进而可以满足不同的连接方式。
