Abstract
The utility model belongs to the field of fasteners and discloses a multi-purpose external hexagonal bolt, which comprises a screw. The upper end of the screw is provided with an external hexagon. The multi-purpose external hexagonal bolt is characterized in that the external hexagon is provided with an internal hexagon. The concave surface of the internal hexagon is provided with a screwdriver slot. According to the technical scheme of the utility model, the external hexagon is provided with the internal hexagon and the concave surface of the internal hexagon is provided with the screwdriver slot. In this way, when the external hexagonal bolt is incapable of being assembled or disassembled within a narrow space by means of an external hexagonal wrench, the external hexagonal bolt can still be assembled or disassembled within the narrow space by means of an internal hexagonal wrench or a screwdriver. Therefore, the external hexagonal bolt is more convenient and practical to use.
Description
Technical field
The utility model relates to a kind of fastener areas, specifically refers to relate to a kind of multipurpose outer-hexagonal 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: when the outer-hexagonal bolt will be fixedly connected in the narrow space, installing or dismounting outer-hexagonal bolt will use the outer-hexagonal spanner time, can't use the outer-hexagonal spanner owing to the restriction in space, when installing or dismantle, bring some troubles for the outer-hexagonal 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 multipurpose outer-hexagonal bolt, solving existing outer-hexagonal bolt will be fixedly connected in the narrow space, installing or dismounting outer-hexagonal bolt will use the outer-hexagonal spanner time, can't use the outer-hexagonal spanner owing to the restriction in space, the problem of when installing or dismantle, making troubles for the outer-hexagonal 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 multipurpose outer-hexagonal bolt, comprise described screw rod, and described screw rod upper end is provided with outer-hexagonal, and described outer-hexagonal is provided with interior hexagonal, and the concave surface of described interior hexagonal is provided with driver flutes.
The utility model compared with prior art has following beneficial effect:
The utility model is owing to be provided with interior hexagonal at outer-hexagonal, concave surface in interior hexagonal is provided with driver flutes, to in narrow space, install or dismantle to use the outer-hexagonal spanner time when the outer-hexagonal bolt like this, also can use inner hexagon spanner or screwdriver tool, make the more convenient practicality of outer-hexagonal bolt.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the structural representation of a kind of multipurpose outer-hexagonal of the utility model bolt.
The number in the figure explanation:
The 1-screw rod, 2-outer-hexagonal, 3-driver flutes, hexagonal in the 4-.
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 multipurpose outer-hexagonal bolt comprises described screw rod 1, and described screw rod 1 upper end is provided with outer-hexagonal 2, and described outer-hexagonal 2 is provided with interior hexagonal 4, and the concave surface of described interior hexagonal 4 is provided with driver flutes 3.
This outer-hexagonal bolt will be installed in narrow space or dismantle and can't use the outer-hexagonal spanner time, also can use inner hexagon spanner or screwdriver tool, makes the more convenient practicality of outer-hexagonal bolt.
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.
