Abstract

The utility model discloses a half-thread screw with a nut-hole octagonal flanged head, which comprises a screw body. The screw body is provided with a stem body and a tail end body which are molded integrally, the head end of the stem body is radially equipped with a continuous external thread body with an external concave-convex tooth slot structure, thread axial length of the external thread body is no more than 2/3 of the length of the stem body, the tail end of the screw body is axially equipped with a continuous internal thread body with an internal concave-convex tooth slot nut hole structure, the length of the internal thread body is at least equal to that of the tail end body, and the screw body is a sixth structure body of an octagonal flanged head shaped body. The half-thread screw is novel in structure and fast in manufacturing by arranging a concave thread hole at the tail end, the concave thread hole is moderate in aperture, a new rear output connecting form is added, structural strength of the original screw body can not be affected on the basis of keeping properties of the original screw body, and the thread hole is manufactured into threads with different specifications, such as metric threads, inch threads and standard screw threads, thereby meeting requirements of different connecting modes.

Description

Partial thread screw with the anistree collar head in female hole

Technical field

The utility model relates to the technical field of fastening piece in the five metals element, particularly with the partial thread screw of the anistree collar head in female hole.

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 partial thread screw of structural strength jail and the anistree collar head in the female hole of band 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 the anistree collar head in female hole, 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 anistree protruding rafter 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, the 5th spanner edge of Octagon layouts such as rear end, the 6th tail end body border is shaped on, and the 6th tail end body border front end also is shaped on the first protruding rafter anchor ring; 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 shaft core position of the 6th tail end body; The 6th tapped hole nominal diameter value equals 1/3rd of the 6th 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, 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 anistree protruding rafter 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 the anistree collar head in female hole, 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 16 of anistree protruding rafter head shapes body.

The utility model embodiment, shown in Fig. 1, Fig. 1 a, Fig. 1 b, the screw body is the 6th structure 16 of anistree protruding rafter head shapes body, 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, the 5th spanner edge 16c of Octagon layouts such as rear end, the 6th tail end body 16b border is shaped on, and the 6th tail end body 16b border front end also is shaped on the first protruding rafter anchor ring 16e; 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 shaft core position of the 6th tail end body 16a; The 6th tapped hole 16d nominal diameter value equals 1/3rd of the 6th body 16a of 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.
