Abstract

The utility model discloses a full thread screw with a female hole and a straight square head structure, which comprises a screw main body, wherein the screw main body comprises a rod part body and a tail end part body which are integrally formed; the head end of the rod part body is radially provided with an external thread body with a continuous external concave-convex gear groove structure, and the axial length of the thread of the external thread body is equal to that of the rod part body; the tail end of the screw main body is axially provided with an internal screw body with a continuous internal concave-convex gear groove female hole structure, and the length of the internal thread body is at least equal to that of the tail end part body; and the screw main body is a straight square head-shaped first structure body. As the tail part is provided with the concave thread hole, the screw is novel in structure and convenient in manufacture; as the diameter of the concave thread hole is proper, the screw keeps the original performance of the screw body, increases a new rear part output connection mode, and can not influence the structure intensity of the original screw body; and as the thread hole is designed to be thread modes with different specifications, the screw can satisfy different connection modes.

Description

Full thread screw with female hole one word square toes structure

Technical field

The utility model relates to the technical field of hardware fastening, particularly with the full thread screw of female hole one word square toes 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 full thread screw of structural strength jail and the female hole of band one word square toes structure 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 one word square toes 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 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 a word square toes shape body.

The measure of taking also comprises:

The first above-mentioned structure front end is shaped on the first bar portion body; The first bar portion body tail end is the first tail end body, and is shaped on a word translot of indent in the middle of the afterbody of this first tail end body; 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 central position of the first 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 the screw body is first structure of a word square toes 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 one word square toes 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 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 a word square toes shape body.

The utility model embodiment, shown in Fig. 1, Fig. 1 a and Fig. 1 b, 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 is shaped on a word translot 11c of indent in the middle of the afterbody of this first tail end body 11b; 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 central position of the first tail end body 11b.

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.
