Get loose easily.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
The structural representation of the high-strength bolt that Fig. 1 provides for this utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained all other embodiments, broadly fall into the scope of this utility model protection.
Such as Fig. 1, this utility model embodiment provides a kind of high-strength bolt, including metal bolts 1 be sheathed on described gold
Belonging to the nonmetal external member 2 outside bolt 1, described nonmetal external member 2 is insulator, by phenolic resin and the group of high-strength structureal adhesives
Compound is fabricated by so that described high-strength bolt can apply in electrolysis bath, it is not necessary to additionally uses insulation tube, can be effective
Reduce maintenance cost and Master Cost.
Such as Fig. 1, described metal bolts 1 includes bolt head 11 and the shank of bolt 12 being connected with described bolt head 11, described non-
