By adopting technique scheme, bolt head is fixed by the two-sided cushion rubber of locating shim lower surface and existing adhering components, make bolt construction will not produce the phenomenon that bolt follows nut to rotate together, and locating shim is spacing with the locating groove clamping on bolt head lower surface by locating convex block, locating shim and bolt head can be separately manufactured, reasonable in design, simple in construction, easy to assembly, location is reliable, greatly reduces difficulty of construction；And enhancement Layer can improve the intensity of screw rod, thus extending the service life of bolt, practicality is good.
This utility model is further arranged to: described bolt head and screw rod are made by No. 45 steel, and described enhancement Layer is welded by high strength titanium alloy material.By this setting, high strength titanium alloy material the enhancement Layer intensity made is high, corrosion resistance is good, thermostability is high so that bolt longer service life.
This utility model is further arranged to: described nut locating part includes the rustless steel latch mated with described connecting hole and the rustless steel shell fragment being welded on rustless steel latch one end, described rustless steel latch and connecting hole grafting are fixed, and rustless steel shell fragment withstands the locking nut lower surface of top.By this setting, nut locating part simple in construction, low cost of manufacture.
This utility model is further arranged to: described locating shim is made by 304 stainless steel materials, and the thickness of locating shim adopts 2mm.By this setting, locating shim thickness is arranged rationally, and will not get rusty, long service life.
This utility model is further arranged to: the thickness of described enhancement Layer is 1-4mm.By this setting, enhancement Layer thickness arranges rationally, and intensity is good.
The utility model has the advantages that: compared with prior art, it is more reasonable that this utility model structure is arranged, bolt head is fixed by the two-sided cushion rubber of locating shim lower surface and existing adhering components, make bolt construction will not produce the phenomenon that bolt follows nut to rotate together, and locating shim is spacing with the locating groove clamping on bolt head lower surface by locating convex block, locating shim and bolt head can be separately manufactured, reasonable in design, simple in construction, easy to assembly, location is reliable, greatly reduces difficulty of construction；And enhancement Layer can improve the intensity of screw rod, thus extending the service life of bolt, practicality is good.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
