Abstract
The utility model discloses a biconic eccentric expansion bolt assembly, which comprises a screw bolt body with a tapered cap, an expansion casing sheathed with the screw bolt body and a screw nut matched with the screw bolt. Wherein, the screw bolt body is a reduced eccentric cylinder. The biconic eccentric expansion bolt assembly has the advantages that the structure is simple, the distance and the height between two screw bolts can be adjusted, the deflection of the dangler is effectively prevented, the use is easy, the installation is firm and reliable, and the construction quality is effectively improved.
Description
Technical field
The utility model is a kind of bipyramid eccentric expansion bolt assembly.
Summary of the invention
At present, setscrew commonly used generally is by bolt, expansion sleeve, and nuts and washers is formed.During use, need put into the expansion sleeve of strap bolt behind the hole of getting certain depth and diameter on the building, fastening nut, the bolt of band tapering cap can the dilating expansion covers, and setscrew is fixed on the building firmly.Adopt the bolt of said structure, when the wall epidermis of building is hard material such as ceramic tile, the inclined to one side phenomenon of basic hole drill often occurs,, will cause the deflection of hanger even can't hang sometimes because of the deviation slightly of the distance between two setscrews.
The utility model is at the existing in prior technology problem, and provide have simple in structure, easy to use, can adjust between two bolts distance and the height, effectively prevent the technological scheme of the bipyramid eccentric expansion bolt assembly of hanger deflection, it is the reducing eccentric cylinder that this scheme adopts the body of bolt.
The utility model is realized by following technical measures: it comprises the body of bolt that has tapered cap, is enclosed within the expansion sleeve on the body of bolt, with body of bolt nut engaged, it is characterized in that: the described body of bolt is the reducing eccentric cylinder.The concrete characteristics of this programme also have: described reducing eccentric cylinder comprise the ganoid thick cylinder that has tapered cap with this cylinder disalignment and the fine thread post of fixedlying connected, the screw column tail end is provided with anti-collision body.Tapered pad, packing ring are installed between expansion sleeve and nut on the described body of bolt in turn.Described packing ring comprises: plain washer and elastic washer.Described expansion sleeve two ends are provided with expansion joint (E.J.).Described expansion joint (E.J.) is axially, and each end has three, and wherein one length is identical with the length of expansion sleeve, and they are distributed on the same circumferential surface.The described body of bolt is provided with a through hole near an end of tapered cap, and passing an expansion joint (E.J.) has a locating stud and through hole interference fit.
The beneficial effect of this programme can be learnt according to the narration to such scheme, the described body of bolt is the reducing eccentric cylinder, can utilize eccentric screw column partly to adjust distance and height between two bolts, effectively prevents the hanger deflection, easy to use, can effectively improve construction quality; Described screw column tail end is provided with anti-collision body, and is simple in structure, and easily processing can reduce the extrusion-deformation that bolt tail is caused by knocking; Tapered pad, packing ring are installed between expansion sleeve and nut on the described body of bolt in turn, and the tapered pad structure of setting up has increased the thermal expansion of expansion sleeve, has strengthened the area of contact of expansion sleeve and body of wall, makes it in conjunction with firmly, is difficult for loosening; The described body of bolt is provided with a through hole near an end of tapered cap, and passing an expansion joint (E.J.) has a locating stud and through hole interference fit, prevents the normally spinning in and out of nut of trackslipping in expansion sleeve and causing owing to the body of bolt.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
