Clearer, below in conjunction with the present invention for the purpose making the present invention implement, technical scheme and advantage
Accompanying drawing in embodiment, is further described in more detail the technical scheme in the embodiment of the present invention.Attached
In figure, the most same or similar label represents same or similar element or has same or like
The element of function.Described embodiment is a part of embodiment of the present invention rather than whole embodiments.
The embodiment described below with reference to accompanying drawing is exemplary type, it is intended to be used for explaining the present invention, and can not
It is interpreted as limitation of the present invention.Based on the embodiment in the present invention, those of ordinary skill in the art are not having
Have and make the every other embodiment obtained under creation type work premise, broadly fall into the model of present invention protection
Enclose.Below in conjunction with the accompanying drawings embodiments of the invention are described in detail.
In describing the invention, it is to be understood that term " " center ", " longitudinally ", " laterally ",
"front", "rear", "left", "right", " vertically ", " level ", " top ", " end ",
The orientation of the instruction such as " interior ", " outward " or position relationship are to close based on orientation shown in the drawings or position
System, be for only for ease of describe the present invention and simplify describe rather than instruction or hint indication device or
Element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this
The restriction of invention protection domain.
As it is shown in figure 1, the fastening bolt device of the present invention include main body bolt the 1, first slide block 2,
Second slide block 3, jacking block 4, hold out against screw 5 and nut 6, for by upper structural member 7 and lower structural member 8
Fastening, the first slide block 2 and the second slide block 3 be placed in main body bolt 1, jacking block 4 be placed in slide block 2 and
Above slide block 3, hold out against screw 5 and be placed in above jacking block 4 and with main body bolt 1 by threaded engagement, top
Block 4 is fitted by the conical surface with the first slide block 2 and the second slide block 3, and jacking block 4 can axial along main body bolt
Sliding, the screw portion of main body bolt 1 is placed in the through hole of structural member 7 and lower structural member 8, main body
The half of screw of bolt 1 coordinates with the through hole of lower structural member 8.
