Abstract
The utility model discloses a bolt with supplementary spiral shell head, including spiral shell head, supplementary spiral shell head, screw rod, the spiral shell head be regular hexagon's hexagonal drive head for the cross section, spiral shell head bottom connect fixedly supplementary spiral shell head, supplementary spiral shell head bottom fixed connection the screw rod, the screw rod be the cylinder structure, be provided with the screw thread on the screw rod surface, spiral shell head, supplementary spiral shell head, screw rod vertical the central axis point -blank, wherein, supplementary spiral shell head be hexagonal drive head, the size is less than the spiral shell head. In this way, the utility model provides a wrong atress is pulled in the supplementary spiral shell head dispersion of bolt accessible, pulls in wrong at luo touchu, utilizes supplementary spiral shell head assist the wrong work of pulling, makes to pull and twists the atress dispersion, pulls wrongly lighter, and the practicality is strong.
Description
Technical field
This utility model relates to fixing member arts, particularly relates to a kind of bolt with auxiliary screw head.
Background technology
Bolt is the one of machine components, the threaded securing member of cylinder of adapted nut, by a head and screw rod class securing member dimerous, need and nut screw connection, for being fastenedly connected two parts with through hole, at present, bolt arrangement on market is similar to, mostly being solid construction, twisting mode is all screw head to be clamped by spanner, then screws, twisting mode is single, and twisting is very painstaking, spanner stress point in screw head is few, operates the lightest.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of bolt with auxiliary screw head, it is possible to by auxiliary screw head dispersion twisting stress, while carrying out twisting at screw head, auxiliary screw head is utilized to carry out assisting twisting work, making twisting force dispersion, twisting is lighter, practical.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of bolt with auxiliary screw head, it is characterized in that, including: screw head, auxiliary screw head, screw rod, described screw head be cross section be orthohexagonal hexagonal screw head, fixing described auxiliary screw head is connected bottom described screw head, the screw rod described in connecting is fixed bottom described auxiliary screw head, described screw rod is cylindrical structure, it is provided with screw thread on screw rod outer surface, described screw head, auxiliary screw head, the vertical central axis of screw rod is point-blank, wherein, described auxiliary screw head is hexagonal screw head, size is less than screw head.
In one preferred embodiment of this utility model, described screw head, auxiliary screw head, screw rod material are carbon steel.
In one preferred embodiment of this utility model, in the regular hexagon of described auxiliary screw head cross section, it is connected to the circle of screw rod cross section.
In one preferred embodiment of this utility model, the height of described auxiliary screw head is identical with the height of described screw head.
The beneficial effects of the utility model are: bolt provided by the utility model can be by auxiliary screw head dispersion twisting stress, while carrying out twisting, utilize auxiliary screw head to carry out assisting twisting work, make twisting force dispersion at screw head, and twisting is lighter, practical.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of bolt one preferred embodiment with auxiliary screw head of this utility model；
In accompanying drawing, the labelling of each parts is as follows: 1-screw head, 2-assist screw head, 3-screw rod.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, this utility model embodiment includes:
A kind of bolt with auxiliary screw head, it is characterized in that, including: screw head 1, auxiliary screw head 2, screw rod 3, described screw head 1 is orthohexagonal hexagonal screw head for cross section, fixing described auxiliary screw head 2 is connected bottom described screw head 1, the screw rod 3 described in connecting is fixed bottom described auxiliary screw head 2, described screw rod 3 is cylindrical structure, it is provided with screw thread on screw rod 3 outer surface, described screw head 1, auxiliary screw head 2, screw rod 3 vertical central axis point-blank, wherein, described auxiliary screw head 2 is hexagonal screw head, and size is less than screw head 1.
Described screw head 1, auxiliary screw head 2, screw rod 3 material are carbon steel.
Being connected to the circle of screw rod 3 cross section in the regular hexagon of described auxiliary screw head 2 cross section, do not affect the normal use of screw rod, the spanner meeting different size carries out twisting.
The height of described auxiliary screw head 2 is identical with the height of described screw head 1.
Bolt provided by the utility model can be by auxiliary screw head dispersion twisting stress, while carrying out twisting, utilizes auxiliary screw head to carry out assisting twisting work, makes twisting force dispersion at screw head, and twisting is lighter, practical.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
