Abstract
The invention discloses a hexagonal bolt comprising a bolt head and a bolt rod which are integrally formed. The bolt head is shaped in a regular hexagon. The hexagonal bolt is characterized in that six bolt head chamfers are formed on one surface of the bolt head distant from the bolt rod at six angles of the regular hexagon, and a figure enclosed by the bolt head chamfers is shaped in an inscribed circle of the regular hexagon. The inside of the bolt rod is of hollow cylinder structure, and the bolt head and the bolt rod are connected to form a hollow cone structure inside. The hexagonal bolt has the advantages of simple structure, and a screw hole on the bolt rod provides a novel way to detach the hexagon bolt.
Description
Technical field
The present invention relates to a kind of fastening piece, particularly a kind of hex head bolt.
Background technique
Hex head bolt is a kind of common connection fastening piece, must be indispensable in industrial production and Assembling Production.Hex head bolt can only be wrenched and unclamp with hexagon wrench, and tool using is single.But be wrenched and unclamp inconvenience and hard by spanner.
Summary of the invention
Be to solve the deficiencies in the prior art, the object of the present invention is to provide a kind of screw to be located at hex head bolt on the screw rod.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
A kind of hex head bolt, comprise integrated bolt head and bolt shank, the external frame of above-mentioned bolt head is regular hexagon, it is characterized in that, above-mentioned bolt head forms six bolt head chamferings away from the one side of above-mentioned bolt shank at orthohexagonal six angles, and the figure that above-mentioned bolt head chamfering surrounds is orthohexagonal incircle; Above-mentioned bolt shank inside is the hollow cylinder structure, and the inside that above-mentioned bolt head is connected with bolt shank is formed with the hollow cone body structure.
Say that further above-mentioned bolt head and bolt shank joint are formed with ledge structure; Above-mentioned bolt shank is cylinder, and is formed with the bolt shank chamfering on its circumference away from an end of above-mentioned bolt head.
Say that further the angle of above-mentioned bolt head chamfering is 10 ° to 20 °, the angle of above-mentioned bolt shank chamfering is 30 ° to 45 °.
Say that further the length of above-mentioned bolt shank is 60 ± 0.5mm, the external diameter of above-mentioned bolt shank is 20 ± 0.5mm, and the internal diameter of above-mentioned bolt shank is 13 ± 0.5mm.
Say that further the hollow cylinder structure length of above-mentioned bolt shank inside is 61.5 ± 0.5mm, the cone angle of above-mentioned hollow cone is 100 ° to 130 °.
Usefulness of the present invention is: simple in structure, the screw on the screw rod provides new mode for the dismounting hex head bolt.
