Abstract
The utility model discloses a metal hanging anchor-bolt, comprising a screw rod, a casing tube and a taper cap nut. Wherein, the casing tube is arranged at one end with at least two slits that is of flare shape. The screw rod's one end passes through the casing tube and is screwed up fixedly with the taper cap nut. The slit one end of the casing tube responds to the taper cap nut, while the other slit end relative to the casing tube is provided with a hex nut on the screw rod. The utility model adopts a dismountable way of integrated screw rod and taper cap nut, and is of convenient installation, repeated use and high anchoring strength.
Description
Technical field
The utility model relates to a kind of metal crab-bolt.
Background technique
Metal is hung crab-bolt and has been widely used at aspects such as buildings, but currently used crab-bolt normally crab-bolt head and leading screw is an one, and this structure anchor intensity is low, can not dismantle and reuse, can not integral installation, also need with other annex supporting during installation with it.
The model utility content
At problems of the prior art, the purpose of this utility model be to provide a kind of anchoring strength height, detachable, can reuse and metal easy for installation is hung crab-bolt.
For achieving the above object, the utility model metal is hung crab-bolt and is comprised: leading screw, sleeve pipe and tapering nut, one end of sleeve pipe has 2 above jags, being shaped as of jag is tubaeform, one end of leading screw passes described sleeve pipe and tightens fixing mutually with described tapering nut, one end of described sleeve pipe jag is relative with described tapering nut, on described leading screw hexagon nut is installed with respect to the other end of described sleeve pipe jag.
Further, a pad is installed between described hexagon nut and the described sleeve pipe.
Further, described pad has a boss, and the outside dimension of boss and described casing inner diameter are complementary.
Further, also be provided with on the described tapering nut with described sleeve pipe on the positive stop key that is complementary of jag.
Further, the surface of the jag position of described sleeve pipe also is provided with anti-skidding reticulate pattern.
The removably that the utility model adopts leading screw to combine with the tapering nut, not only easy for installation, reusable, and the anchoring strength height.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment:
As shown in drawings, one end of sleeve pipe 4 has 3 jags, being shaped as of jag is tubaeform, one end of leading screw 1 passes sleeve pipe 4 and tightens fixing mutually with tapering nut 5, one end of sleeve pipe 4 jags is relative with tapering nut 5, the other end with respect to sleeve pipe 4 jags is equipped with hexagon nut 2 on leading screw 1, installation one has the pad 3 of boss between hexagon nut 2 and the sleeve pipe 4, the internal diameter of the outside dimension of boss and sleeve pipe 4 is complementary, also be provided with on the tapering nut 5 with sleeve pipe 4 on the positive stop key that is complementary of jag, the surface of the jag position of sleeve pipe 4 also is provided with anti-skidding reticulate pattern.During use, rotating hexagon nut 2 makes tapering nut 5 snap in sleeve pipe 4, can rotation when the positive stop key on the tapering nut 5 has guaranteed that tapering nut 5 tightens and make the jag of sleeve pipe 4 to expand gradually mutually with sleeve pipe 4, anti-skidding reticulate pattern on the sleeve pipe 4 also has the effect of strengthening anchoring strength, and the pad 3 of band boss has guaranteed that sleeve pipe 4 can not rock.During dismounting, rotating threaded shaft 1 just can directly be dismantled.
