Abstract

The utility model discloses a hexagonal full-thread screw with a female hole, which 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 rod part body, and the thread axial length ofeach 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 thetail 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 first structure with a hexagon 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 outputconnection 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 such as international threads, British standard threads, American standard threads, and thelike.

Description

Full thread screw with female hole hexagonal configuration

Technical field

The utility model relates to the technical field of fastening piece in the five metals element, particularly with the full thread screw of female hole hexagonal configuration.

Background technique

Fastening pieces such as general screw, 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 full thread screw of structural strength jail and the female hole of band hexagonal configuration applied widely.

The utility model solves the problems of the technologies described above the technological scheme that is adopted: with the full thread screw of female hole hexagonal configuration, 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 the screw body is first structure of hexagon head shape body.

The measure of taking also comprises:

The first above-mentioned structure front end is shaped on the first bar portion body, and the first bar portion body tail end is the first tail end body, and this first tail end body border such as is shaped at the first spanner edge of hexagonal arrangement; The interior shaggy tooth cell body that the first structure tail end is shaped on is first tapped hole, and this first tapped hole is positioned at the shaft core position of the first tail end body; The first tapped hole nominal diameter value equals 1/3rd of the first bar portion body diameter value at least.

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 the screw body is first structure of hexagon 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, full thread screw with female hole hexagonal configuration, 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 the screw body is first structure 11 of hexagon head shape body.

The utility model embodiment, shown in Fig. 1, Fig. 1 a, Fig. 1 b, the screw body is first structure 11 of hexagon head shape body, these first structure, 11 front ends are shaped on the first body 11a of bar portion, the first bar portion body 11a tail end is the first tail end body 11b, and this first tail end body 11b border such as is shaped at the first spanner edge 11c of hexagonal arrangement; The interior shaggy tooth cell body that first structure, 11 tail ends are shaped on is the first tapped hole 11d, and this first tapped hole 11d is positioned at the shaft core position of the first tail end body 11a; The first tapped hole 11d nominal diameter value equals 1/3rd of the first body 11a of the bar portion diameter value at least.

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.
