Abstract
The utility model discloses a Full-thread screw with a female hole cross-shaped raised countersunk head. The full-thread screw comprises a screw body, wherein the screw body is provided with a rod part body and a tail end 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 rodpart body, and the thread axial length of each external screw body is equal to the length of the rod part body; and 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 a sixth structure with a cross-shaped raised countersunk 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 holes are 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 the requirements of different connection methods can be further met by manufacturing the thread holes into threads with different specifications.
Description
Technical field
The utility model relates to the technical field of hardware fastening, particularly is with female hole cross half countersunk full thread screw.
Background technique
General fastening pieces such as screw traditionally, it mainly utilizes, and a body of the screw thread of bar portion and afterbody is realized unidirectionally tightening, and tight etc. being fastenedly connected, so inherent characteristic according to these fastening pieces, we know that its ways of connecting is unidirectional, and if realize the secondary pairing of afterbody, or secondary connects, and it structurally is difficult to reach, as carrying out the secondary pairing of fastening piece afterbody really, must carry out hole processing or rod member welding operation to original fastening piece; When the actual production line was operated, it had inconvenience more like this, and working efficiency is also comparatively low.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of novel structure, making is convenient, switching performance increases, structural strength jail and the female hole of band cross half countersunk full thread screw applied widely.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: be with female hole cross half countersunk full thread screw, comprise the screw body, this screw body has integrated bar portion's body and tail end body, bar portion body head end radially is shaped on the outside thread body of continuous outer concavo-convex teeth groove structure, and the screw thread axial length of this outside thread body equals bar portion body length; Screw body tail end axially is shaped on the internal thread body of the female hole structure of continuous interior shaggy tooth groove, and the length of this internal thread body equals the length value of tail end body at least, and described screw body is the 6th structure of cross countersunk raised head shape body.
The measure of taking also comprises:
The 6th above-mentioned structure front end is shaped on the 6th bar portion body; The 6th bar portion body tail end is the 6th tail end body, and is shaped on the criss-crossing groove of indent in the middle of the afterbody of the 6th tail end body; The interior shaggy tooth cell body that the 6th structure tail end is shaped on is the 6th tapped hole, and the 6th tapped hole is positioned at the central position of the 6th tail end body.
Compared with prior art, the utility model comprises the screw body, this screw body has integrated bar portion's body and tail end body, and bar portion body head end radially is shaped on the outside thread body of continuous outer concavo-convex teeth groove structure, and the screw thread axial length of this outside thread body equals bar portion body length; Screw body tail end axially is shaped on the internal thread body of the female hole structure of continuous interior shaggy tooth groove, and the length of this internal thread body equals the length value of tail end body at least, and described screw body is the 6th structure of cross countersunk raised head shape body.Advantage of the present utility model is: adopts and is shaped on concave screw hole at afterbody, and its novel structure, it is convenient to make; Its aperture of concave screw hole is moderate, when keeping former screw body performance, has increased new rear portion output Placement, and also can not influence the structural strength of former screw body; This tapped hole is made the engage thread of different size, and then can satisfy different Placements, as metric thread, inch screw thread, U.S. standard screw thread etc.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
The utility model embodiment, be with female hole cross half countersunk full thread screw, comprise the screw body, the screw body has integrated bar portion's body and tail end body, bar portion body head end radially is shaped on the outside thread body of continuous outer concavo-convex teeth groove structure, and the screw thread axial length of this outside thread body equals bar portion body length; Screw body tail end axially is shaped on the internal thread body of the female hole structure of continuous interior shaggy tooth groove, and the length of this internal thread body equals the length value of tail end body at least, and described screw body is the 6th structure 16 of cross countersunk raised head shape body.
The utility model embodiment, shown in Fig. 1, Fig. 1 a, Fig. 1 b, the screw body is that the 6th structure 16, the six structures 16 front ends of cross countersunk raised head shape body are shaped on the 6th body 16a of bar portion; The 6th bar portion body 16a tail end is the 6th tail end body 16b, and is shaped on the criss-crossing groove 16c of indent in the middle of the afterbody of the 6th tail end body 16b; The interior shaggy tooth cell body that the 6th structure 16 tail ends are shaped on is the 6th tapped hole 16d, and the 6th tapped hole 16d is positioned at the central position of the 6th tail end body 16b.
Advantage of the present utility model is: adopts and is shaped on concave screw hole at afterbody, and its novel structure, it is convenient to make; Its aperture of concave screw hole is moderate, when keeping former screw body performance, has increased new rear portion output Placement, and also can not influence the structural strength of former screw body; This tapped hole is made the engage thread of different size, and then can satisfy different Placements, as metric thread, inch screw thread, U.S. standard screw thread etc.
Most preferred embodiment of the present utility model is illustrated, and various variations or the remodeling made by those of ordinary skills can not break away from scope of the present utility model.
