Abstract
The utility model belongs to the field of a fastening piece and discloses a bolt with double-ended screw rods. The bolt with the double-ended screw rods disclosed by the utility model is characterized in that a first screw rod is arranged at the lower end of an outer hexagonal screw head and a second screw rod is arranged on the upper end of the outer hexagonal screw head; and the axis of the first screw rod and the axis of the second screw rod are on a same straight line. The bolt with the double-ended screw rods disclosed by the utility model has the beneficial effects that the structure of the bolt is improved and one screw rod is added to the common outer hexagonal screw head, so that when the bolt is fixedly mounted on a mechanical article, a nut matched with the bolt can be arranged on the screw rod at the other end of the outer hexagonal screw head; and the diameters of the double-ended screw rods are different, and the bolt can be suitably mounted and fixed in threaded holes with different sizes, so that the practical function of the bolt is wider.
Description
Technical field
The utility model relates to a kind of fastener areas, specifically is meant to relate to a kind of bolt with double threaded screw.
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: common standard part bolt is on being fixed on instruments and articles the time, have only an end screw rod, and the nut that matches can't be installed on the bolt that has installed and fixed again.
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 bolt with double threaded screw, solve existing common standard part bolt on being fixed on instruments and articles the time, have only an end screw rod, and the problem of the nut that matches can't be installed on the bolt that has installed and fixed again.
The purpose of this utility model is to realize by following technical solution:
The technical solution of the utility model is: a kind of bolt with double threaded screw, comprise that described first screw rod is arranged at the lower end of outer-hexagonal spiral shell head, described second screw rod is arranged at the upper end of outer-hexagonal spiral shell head, same the straight line in the shaft axis place of the shaft axis of described first screw rod and second screw rod.
Preferably, the diameter of described first screw rod is greater than the diameter of second screw rod.
The utility model compared with prior art has following beneficial effect:
The utility model improves on the structure of bolt, on common outer-hexagonal bolt, increased by a screw rod again, when making bolt on being fixed on instruments and articles, the nut that matches can also be installed on the screw rod of the bolt the other end again, and two screw diameter of this bolt varies in size and can be fit to be fixed in the different big or small tapped holes, makes that the utility function of this bolt is wider.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is a kind of bolt arrangement schematic representation with double threaded screw of the utility model.
The number in the figure explanation:
1-outer-hexagonal spiral shell head, 21-first screw rod, 22-second screw rod.
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 bolt with double threaded screw, comprise that described first screw rod 21 is arranged at the lower end of outer-hexagonal spiral shell head 1, described second screw rod 22 is arranged at the upper end of outer-hexagonal spiral shell head 1, same straight line in shaft axis place of the shaft axis of described first screw rod 21 and second screw rod 22.
Further, the diameter of described first screw rod 21 is greater than the diameter of second screw rod 22.
This bolt on being fixed on instruments and articles in, the nut that matches can also be installed on the screw rod of the bolt the other end again, and two screw diameter of this bolt varies in size and can be fit to be fixed in the different big or small tapped holes, makes that the utility function of this bolt is wider.
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.
