Description
Technical field
This utility model relates to bolt technical field, is specially a kind of high intensity flat head bolt.
Background technology
Traditional bolt is in use, easily there is crack in junction between shank of bolt and bolt head, the service life causing bolt shortens, simultaneously, traditional bolt is in use, because of design reason, its force part, mainly in the junction of bolt head Yu shank of bolt, causes the junction between shank of bolt and bolt head crack easily occur.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide the flat head bolt of a kind of high intensity.
For achieving the above object, this utility model provides following technical scheme: a kind of high intensity flat head bolt, including the bolt head being connected and shank of bolt, described shank of bolt is connected by rib with bolt head, being additionally provided with forced section on described shank of bolt, the distance between described forced section and rib is 1mm, and described bolt head is provided with several reinforcements around rib, one end of each reinforcement is connected with rib respectively, and the other end is provided with chamfering.
Further, described forced section includes that the first side and the second side, the first side are provided with the first ring-type transition cambered surface with the outer surface of shank of bolt, and the second side is provided with the second ring-type transition cambered surface with the outer surface of shank of bolt.
Further, described rib is provided with the 3rd ring-type transition cambered surface with the junction of shank of bolt.
Further, described rib is cylindrical shape, and the exterior contour of forced section is cylindrical shape, and the diameter of described rib is more than the diameter of forced section, and the diameter of forced section is more than the diameter of shank of bolt.
Further, the bar number of described reinforcement is six, and the angle between two reinforcements of arbitrary neighborhood is identical, and is 60 degree.
Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that this utility model provides is brought: the 1. shank of bolt described in is connected by rib with bolt head, described bolt head is provided with several reinforcements around rib, one end of each reinforcement is connected with rib respectively, the other end is provided with chamfering, by the design of reinforcement, rib is made to form an entirety with bolt head, add the structural strength of rib, and the junction of rib and shank of bolt is provided with the 3rd ring-type transition cambered surface, designed by the 3rd ring-type transition cambered surface, add the surface stress of shank of bolt and rib junction, and then enhance the structural strength of shank of bolt and rib junction, the phenomenon in crack occurs effectively to prevent shank of bolt and rib junction from occurring.2. it is additionally provided with forced section on shank of bolt, make bolt in use, stress is on shank of bolt, rather than in the junction of shank of bolt Yu bolt head, there is the phenomenon in crack in the junction effectively preventing shank of bolt and bolt head, and described forced section includes the first side and the second side, first side is provided with the first ring-type transition cambered surface with the outer surface of shank of bolt, second side is provided with the second ring-type transition cambered surface with the outer surface of shank of bolt, design by the first ring-type transition cambered surface Yu the second ring-type transition cambered surface, add the surface stress of forced section and shank of bolt junction, add structural strength, there is the phenomenon in crack in the junction effectively preventing forced section and shank of bolt.3. the bar number of reinforcement described in is six, and the angle between two reinforcements of arbitrary neighborhood is identical, and is 60 degree, by above design, make bolt head during stress, each reinforcement can carrying bolt head uniformly, the phenomenon of deformation occurs to prevent bolt head from occurring.

Detailed description of the invention
With reference to Fig. 1-Fig. 3, this utility model is described further.
A kind of high intensity flat head bolt, including the bolt head 1 being connected and shank of bolt 2, described shank of bolt 2 is connected by rib 3 with bolt head 1, it is additionally provided with forced section 4 on described shank of bolt 2, distance between described forced section 4 and rib 3 is 1mm, described bolt head 1 is provided with several reinforcements 5 around rib 3, and one end of each reinforcement 5 is connected with rib 3 respectively, and the other end is provided with chamfering 51.
Described shank of bolt 2 is connected by rib 3 with bolt head 1, described bolt head 1 is provided with several reinforcements 5 around rib 3, one end of each reinforcement 5 is connected with rib 3 respectively, the other end is provided with chamfering 51, design by reinforcement 5, rib 3 and bolt head 1 is made to form an entirety, add the structural strength of rib 3, and the junction of rib 3 and shank of bolt 2 is provided with the 3rd ring-type transition cambered surface 63, designed by the 3rd ring-type transition cambered surface 63, add the surface stress of shank of bolt 2 and rib 3 junction, and then enhance the structural strength of shank of bolt 2 and rib 3 junction, the phenomenon in crack occurs effectively to prevent shank of bolt 2 and rib 3 junction from occurring.
Forced section 4 it is additionally provided with on shank of bolt 2, make bolt in use, stress is on shank of bolt 2, rather than in the junction of shank of bolt 2 with bolt head 1, there is the phenomenon in crack in the junction effectively preventing shank of bolt 2 and bolt head 1, and described forced section 4 includes the first side 41 and the second side 42, first side 41 is provided with the first ring-type transition cambered surface 61 with the outer surface of shank of bolt 2, second side 42 is provided with the second ring-type transition cambered surface 62 with the outer surface of shank of bolt 2, by the first ring-type transition cambered surface 61 and design of the second ring-type transition cambered surface 62, add the surface stress of forced section 4 and shank of bolt 2 junction, add structural strength, there is the phenomenon in crack in the junction effectively preventing forced section 4 and shank of bolt 2.
Further, described rib 3 is in cylindrical shape, and the exterior contour of forced section 4 is cylindrical shape, and the diameter of described rib 3 is more than the diameter of forced section 4, and the diameter of forced section 4 is more than the diameter of shank of bolt 2.
The bar number of described reinforcement 5 is six, and the angle between two reinforcements 5 of arbitrary neighborhood is identical, and is 60 degree, by above design, make bolt head 1 during stress, each reinforcement 5 can carrying bolt head 1 uniformly, the phenomenon of deformation occurs to prevent bolt head 1 from occurring.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, those skilled in the art carries out common variations and alternatives in the range of technical solutions of the utility model and should be included in protection domain of the present utility model.
