Abstract
This utility model one double step flat head bolt, relates to Hardware fitting field, including stepped bolt body;Described body is divided into butt end, the first ladder, the second ladder and the end of thread;The boss of multiple radial direction it is provided with in the junction of described first ladder and the second ladder;The described end of thread is provided with metric thread;The axial direction of the described end of thread is provided with mating holes;The inwall of described mating holes is provided with mounting groove;It is additionally provided with butt hole on described butt end.It is more accurate that this double step flat head bolt makes to coordinate with screw connection structure by location structure, connects the most firm.And eliminate stress concentration point by stress relieving hole, make whole bolt play stably fixing effect.
Description
Technical field
This utility model relates to Hardware fitting field, particularly relates to a kind of double step flat head bolt.
Background technology
Known flat head bolt typically comprises the main body in the space being bonded on an edge.This flat head bolt farther includes bar, and bar is connected to bolt block and makes bar make bolt block be located in extended position or retracted position relative to the movement of main body.This connected mode, although connector is simple, assembling easily, but often takies substantial amounts of space, in the occasion having space to limit, tends not to meet design requirement.Especially between sheet material, but current flat head bolt can not quickly finish location and fixing, and fixing after device adjust cumbersome, be unfavorable for producing.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of double step flat head bolt, and it is reasonable in design, simple in construction, solves the problem that connecting portion the most easily produces displacement.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is to provide a kind of double step flat head bolt, including stepped bolt body;Described body is divided into butt end, the first ladder, the second ladder and the end of thread;The boss of multiple radial direction it is provided with in the junction of described first ladder and the second ladder;The described end of thread is provided with metric thread;The axial direction of the described end of thread is provided with mating holes;The inwall of described mating holes is provided with mounting groove;It is additionally provided with butt hole on described butt end.
Preferably, described boss is provided with three;Three bosses are evenly distributed on the rotary surface of the second ladder.
Preferably, described mounting groove is provided with three;Described butt hole also is provided with three;Mounting groove and butt hole are all evenly distributed in revolution circumference.
The beneficial effects of the utility model are: provide a kind of double step flat head bolt, and it is more accurate to make to coordinate with screw connection structure by location structure, connects the most firm.And eliminate stress concentration point by stress relieving hole, make whole bolt play stably fixing effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of double step flat head bolt;
In accompanying drawing, the labelling of each parts is as follows: 1, butt end;2, the first ladder;3, the second ladder;4, the end of thread;5, boss;6, mating holes;7, mounting groove;8, butt hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Referring to accompanying drawing 1, this utility model embodiment includes:
A kind of double step flat head bolt, including stepped bolt body;Described body is divided into butt end the 1, first ladder the 2, second ladder 3 and the end of thread 4, a diameter of 14mm of butt end, a diameter of 10mm of the first ladder 2, a diameter of 8mm of the second ladder 3, and the end of thread 4 is processed the screw thread of M6;The boss 5 of multiple radial direction it is provided with in the junction of described first ladder 2 and the second ladder 3, this boss can not only increase axial intensity, and the cooperation that can carry out, it is when corresponding installing component coordinates to improve mating capability, prevents the structural damage caused because of interference fit;The described end of thread 4 is provided with metric thread;The axial direction of the described end of thread 4 is provided with mating holes 6;The inwall of described mating holes 6 is provided with mounting groove 7;It is additionally provided with butt hole 8 on described butt end 1.Described boss 5 is provided with three;Three bosses 5 are evenly distributed on the rotary surface of the second ladder 3.Described mounting groove 7 is provided with three;Described butt hole 8 also is provided with three;Mounting groove 7 and butt hole 8 are all evenly distributed in revolution circumference.It is more accurate that this double step flat head bolt makes to coordinate with screw connection structure by location structure, connects the most firm.And eliminate stress concentration point by stress relieving hole, make whole bolt play stably fixing effect.
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 fields, the most in like manner it is included in scope of patent protection of the present utility model.
