Abstract

The utility model belongs to the field of fastening pieces, and discloses a bolt with a cone. The bolt with the cone comprises a bolt rod and a hexagonal bolt head, wherein the bolt rod is arranged at the lower end of the hexagonal bolt head; and the bolt is characterized in that the upper end surface of the hexagonal bolt head is connected with an iron cylinder; the upper end surface of the iron cylinder is connected with the bottom surface of the iron cone, and a circular arc groove is formed in the connecting part of the iron cylinder and the iron cone; and axis lines of the bolt rod, the iron cylinder and the iron cone are in the same straight line. The bolt with the cone has the benefits that as the iron cone structure is additionally added on the bolt with the cone, the iron cone at the other end of the bolt can be movably connected with other matched parts while the bolt is mounted, fixed and connected to a machine.

Description

A kind of band cone bolt

Technical field

The utility model relates to a kind of fastener areas, specifically is meant to relate to a kind of band cone bolt.

Background technique

Bolt as a kind of installation and fixedly the fastening piece of section bar be extensive use of by people, the kind that uses bolt in the existing assembly process is a lot, but be the structural design that adopts the bolt standard piece in general mostly, that is to say that each bolt in the section bar installation all is to use with the form of standard piece, in real life, the design that it is found that this bolt standard piece has the following disadvantages: on the machine tool mechanical when using plain bolt to install and fix to connect, often the other end of bolt also needs with the cone of tapering the component that other match to be flexibly connected, and lacks a kind of band cone bolt.

Summary of the invention

For shortcoming and the deficiency that overcomes background technique, the purpose of this utility model is to provide a kind of band cone bolt, solve on the existing machine tool mechanical when using plain bolt to install and fix to connect, often the other end of bolt also needs with the cone of tapering the component that other match to be flexibly connected, and lacks a kind of problem with the cone bolt.

The purpose of this utility model is to realize by following technical solution:

The technical solution of the utility model is: a kind of band cone bolt, comprise described screw rod and hexagonal spiral shell head, described screw rod is arranged at hexagonal spiral shell head lower end, the upper-end surface of described hexagonal spiral shell head is connected with the iron prop body, described iron prop body upper-end surface is connected with the bottom surface of iron cone and the link position place of iron prop body and iron cone has arc groove, and the shaft axis of the shaft axis of described screw rod and iron prop body and the shaft axis of iron cone are in same straight line.

Preferably, described iron prop body length is of a size of 1/2nd of hexagonal spiral shell head thickness size.

The utility model compared with prior art has following beneficial effect:

The utility model has increased the structure of iron cone on the spiral shell head of bolt, realize that bolt installs and fixes when being connected mechanically, can also flexibly connect other component that match on the iron cone of bolt other end.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is a kind of structural representation with the cone bolt of the utility model.

The number in the figure explanation:

The 1-screw rod, 2-hexagonal spiral shell head, 3-iron cone, 4-arc groove, 5-iron prop body.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.

Contrast accompanying drawing 1 as can be known, a kind of band cone bolt, comprise described screw rod 1 and hexagonal spiral shell head 2, described screw rod 1 is arranged at hexagonal spiral shell head 2 lower ends, the upper-end surface of described hexagonal spiral shell head 2 is connected with iron prop body 5, described iron prop body 5 upper-end surfaces are connected with the bottom surface of iron cone 3 and the link position place of iron prop body 5 and iron cone 3 has arc groove 4, and the shaft axis of the shaft axis of described screw rod 1 and iron prop body 5 and the shaft axis of iron cone 3 are in same straight line.

Further, described iron prop body 5 length dimensions are 1/2nd of hexagonal spiral shell head 2 thickness sizes.

This bolt installs and fixes when being connected mechanically, can also flexibly connect other component that match on the iron cone 3 of bolt other end.

Need to prove; below schematically the utility model and mode of execution thereof are described; this description does not have restricted; described in the accompanying drawing also is one of mode of execution of the present utility model; practical structure is not limited thereto; if generally speaking those of ordinary skill in the art is enlightened by it; under the situation that does not break away from the utility model creation aim; without creationary mode of structure and the embodiment who knows each other with this technological scheme that design, all should belong within the protection domain of the present utility model.

Claims
