Abstract
The utility model belongs to bolt technical field, more particularly to a kind of rotating shaft screw bolt, including bolt head and the shank of bolt that is molded on bolt head, shank of bolt is centrally positioned on bolt head, shank of bolt includes threaded portion and light bar portion, and the longitudinal section of the bolt head is semicircle；The utility model has the advantage that：Bolt head uses semi-circular structure, is easier to tighten fixation in installation process, and be difficult loose or dislocation.
Description
Technical field
The utility model belongs to bolt technical field, more particularly to a kind of rotating shaft screw bolt.
Background technology
Bolt belongs to a kind of fastener, is directed to use in the middle of every field, especially using very in mechanical field
It is frequent, bolt is typically made up of bolt head and shank of bolt, existing bolt head typically all uses the bolt head of square structure, such as
Square, regular hexagon；But the bolt of this square structure bolt head is used and is subject to significant limitation, and is installed not
It is convenient, just it is difficult to tighten or unclamp in the case where the instruments such as spanner are lacked；And the bolt of this structure is encountered when mounted
Surface irregularity is to be difficult to tighten fixation, easy loose or dislocation.
Utility model content
The purpose of this utility model is to provide a kind of rotating shaft screw bolt easy for installation, being difficult loosening.
What the purpose of this utility model was realized in：
Rotating shaft screw bolt, including bolt head and the shank of bolt being molded on bolt head, shank of bolt are centrally positioned on bolt head,
Shank of bolt includes threaded portion and light bar portion, and the longitudinal section of the bolt head is semicircle.
The cambered surface of above-mentioned semicircular bolt head is located at by bolt head towards shank of bolt side, the polished rod portion on shank of bolt
Side.
The termination chamfering of above-mentioned threaded portion is set.
The cross section of above-mentioned bolt head is rectangle.
The diameter of the threaded portion on above-mentioned threaded rod and the equal diameters of light bar portion, the diameter of threaded rod are less than or equal to spiral shell
The width of bolt head.
The utility model is prominent and beneficial compared to existing technology to be had the technical effect that：
1st, the utility model bolt head uses semi-circular structure, bolt is installed more with easily tightening fixation, and be difficult pine
It is dynamic to come off.
2nd, the utility model is difficult to use or in the case of lacking the instruments such as spanner in some spanners, can also tighten by hand or
Person unclamps, easy for installation.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is dimensional structure diagram of the present utility model.
Specific embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-Fig. 3：
Rotating shaft screw bolt, including bolt head 1 and the shank of bolt 2 being molded on bolt head 1, shank of bolt 2 are centrally positioned in bolt
On head, shank of bolt 2 includes threaded portion 4 and light bar portion 3, and the longitudinal section of the bolt head 1 is rectangle for semicircle, cross section；
Using the bolt head of this semicircular structure, the fixed effect when attaching nut is tightened more preferably, and can be pulled that cannot use
Tighten by hand or unclamp in the environment of hand or in the case of lacking the instruments such as spanner；The cambered surface 5 of above-mentioned semicircular bolt head 1
Towards the side of shank of bolt 2, the light bar portion 3 on shank of bolt 2 is located at the side by bolt head 1.
The termination chamfering of above-mentioned threaded portion 4 is set, and the design of chamfering causes that the diameter of threaded portion is slightly less than the straight of threaded portion
Footpath, facilitates being screwed into for nut, and chamfering can also avoid threaded portion termination that burr is left after tapping.
The diameter of the threaded portion 4 on above-mentioned threaded rod 2 and the equal diameters of light bar portion 3, the diameter R of threaded rod 2 be less than or
Equal to the width W of bolt head 1.
Above-described embodiment is only preferred embodiment of the present utility model, and protection model of the present utility model is not limited according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by guarantor of the present utility model
Within the scope of shield.
