Abstract
The utility model discloses a half-thread screw with a female screw hole crossed round header structure, which comprises a screw body. The screw body is provided with an integrally formed rod part body and a tail end part body, wherein an external thread body with a continuous external concave-convex alveolus structure is radially formed at the head end of the rod part body, and the axial length of the thread of the external thread body is at most two-thirds of the length of the rod part body; and an internal thread body with a continuous internal concave-convex alveolus female screw hole structure is axially formed at the tail end of the screw body, the length of the internal thread body is at least equal to that of the tail end part body, and the screw body adopts a sixth structural element of a crossed round header shaped body. The inner concave tap holes formed at the tail part are adopted, thereby resulting in novel structure and convenient manufacture; the pore diameter of the inner concave tap holes are moderate, and a new back part output connection method is added without changing the performance of the original screw body or affecting the structural strength thereof; andthe tap holes are made into thread manners with different specifications, thereby satisfying different connection methods, such as metric threads, inch system threads, U.S. standard threads, etc.
Description
Technical field
The utility model relates to the technical field of hardware fastening, particularly with the partial thread screw of female hole cross round platform header structure.
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, the partial thread screw of structural strength jail and the female hole of band cross round platform header structure applied widely.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: with the partial thread screw of female hole cross round platform header structure, 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 2/3rds of bar portion body length at the most; 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 the screw body is the 6th structure of cross round platform head shapes 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, 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 2/3rds of bar portion body length at the most; 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 the screw body is the 6th structure of cross round platform head shapes 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, partial thread screw with female hole cross round platform header structure, 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 2/3rds of bar portion body length at the most; 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 the screw body is the 6th structure 16 of cross round platform head shapes body.
The utility model embodiment, shown in Fig. 1, Fig. 1 a and Fig. 1 b, the 6th structure 16 front ends 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.
