Abstract
The utility model discloses a multifunctional combined metal anchor bolt, comprising a sleeve and a tapered nut. The sleeve is provided with a guide groove along the length direction; the end of the guide groove is provided with a latch hook; the tapered nut comprises a rear tapered section and a front column section which is provided with a locating key; the guide groove is matched with the locating key and the locating groove can be clamped in the guide groove through the latch hook to integrate the tapered nut and the sleeve. Guiding and locating effects can be achieved by arranging the front column section on the tapered nut, the locating key on the front column section and matching the locating key and the guide groove; the elastic resistance is counteracted when the front column section and the sleeve are hung together so as to prevent the tapered nut from separating from the sleeve, thus the tapered nut and the sleeve are an integrated body during transportation and application.
Description
Technical field
The utility model relates to a kind of multipurpose combination metal crab-bolt.
Background technique
Metal is hung (drawing sudden and violent) crab-bolt and has been widely used at aspects such as buildings, and currently used crab-bolt generally includes sleeve pipe, tapering nut and annular shim, and the tapering nut is provided with positive stop key.This structure is separated from each other, and depositing, be easy to lose in the transportation process, particularly annular shim and tapering nut, and need the scene to assemble when using, very inconvenient.The applicant also once at the problems referred to above application to cross the patent No. be 200620120448.8 utility model patent, this novel crab-bolt matches with hook on the sleeve pipe by the positive stop key of tapering nut front end setting, make tapering nut and sleeve pipe be fixed, make its one-tenth as a whole, be convenient to deposit, transport.But because the surface of the tapering nut of this crab-bolt is that conical surface, sleeve pipe are the flake structure that is easy to generate elastic force, also be difficult in the actual processing guarantee that casing inner diameter is identical with the conical surface external diameter of tapering nut engaging place, thereby make that tapering nut and casing clamp are fashionable, can produce the elastic force that stops both engagings, make the fashionable instability of tapering nut and casing clamp, the easy ejection separate like this, and on conical surface, process positive stop key, its processed complex, expense height.
The model utility content
At the problem that prior art exists, the purpose of this utility model is to provide the improved multipurpose combination of a kind of structure metal crab-bolt.
For achieving the above object, a kind of multipurpose combination of the utility model metal crab-bolt comprises sleeve pipe and tapering nut, the sleeve pipe rear portion is provided with the guiding groove that extends along its length direction, be provided with hook near this guiding groove opening, the tapering nut comprises rear portion conical section and anterior cylindrical section, its middle front part cylindrical section is provided with positioning key, tapering nut cylindrical section inserts the sleeve pipe rear end, positioning key on it is positioned at described guiding groove, and match with described hook by positioning key, the tapering nut is mounted on the sleeve pipe.
Further, described sleeve pipe front end also is provided with a pad, and this pad is the T shape that is become by the radial ringed flange that cylindrical section and one end are provided with, and pad is fixed on the sleeve pipe by its cylindrical section plug-in mounting.
Further, described sleeve circumferential is evenly distributed with at least 2 described guiding grooves, and correspondingly, described tapering nut is provided with the positioning key of same quantity, and the opening of each guiding groove is all tubaeform for ease of what described positioning key was snapped in.
Further, the rear end of described positioning key has the awl section that reduces gradually along its length direction radial dimension, be pressed on the conical surface of this awl section by described hook and on the surface of the pressured described tapering nut conical section in described sleeve pipe rear end, make the relative sleeve pipe stable position of tapering nut.
Further, the root of described guiding groove is provided with stress relief hole.
Further, described sleeve pipe also is provided with anti-skidding reticulate pattern near on the outer surface of its rear end.
Further, the internal diameter of the external diameter of described anterior cylindrical section and described sleeve pipe is complementary.
The utlity model has following advantage:
1) by anterior cylindrical section is set on the tapering nut, and forwardly on the cylindrical section positioning key is set, this positioning key matches with guiding groove, play leading role, and make positioning key be mounted in the guiding groove by hook, when anterior cylindrical section and sleeve pipe are sheathed, have eliminated elastic resistance, thereby prevented that the tapering nut breaks away from from sleeve pipe; Like this no matter still in use tapering nut and sleeve pipe all are complete assemblying bodys in transportation process;
2) internal diameter of pad is slightly larger than the internal diameter of tapering nut, can prevent the leading screw double swerve like this, plays effect stable and guiding;
3) the utility model can be arbitrarily and hex head bolt, harness cord screw rod, hook bolt etc. combine, very easy to use.

Embodiment
As shown in Figure 1, a kind of multipurpose combination of the utility model metal crab-bolt comprises: sleeve pipe 4, pad 8 and tapering nut 5, tapering nut 5 comprises rear portion conical section 11 and anterior cylindrical section 10, its middle front part cylindrical section 10 upper edges circumferentially are provided with positioning key 9, sleeve pipe 4 circumferentially be evenly distributed with at least 2 guiding grooves 12, correspondingly, tapering nut 5 is provided with the positioning key 9 of same quantity, tapering nut 5 cylindrical sections insert sleeve pipe 4 rear ends, positioning key 9 on it is positioned at guiding groove 12, and the opening of each guiding groove 12 is all tubaeform for ease of what positioning key 9 was snapped in.Guiding groove 12 openings are provided with hook 6, and the width of positioning key 9 is greater than hook 6 slit, by positioning key 9 with link up with 6 and match, tapering nut 5 is mounted on the sleeve pipe 4.The rear end of positioning key 9 has the awl section that reduces gradually along its length direction radial dimension, be pressed on the conical surface of this awl section and on the surface of pressured tapering nut 5 conical sections in sleeve pipe 4 rear ends by linking up with 6, make the relative sleeve pipe stable position of tapering nut, treat loading screw 1 so that install easily when using.And the internal diameter of the external diameter of anterior cylindrical section 10 and sleeve pipe 4 is complementary, when tapering nut 5 is mounted on the sleeve pipe 4, for the face contact, reduced elastic resistance greatly between it, prevent that tapering nut 5 breaks away from from sleeve pipe 4, makes it mount structure in aggregates thereby play.
Also be provided with pad 8 on the front end of sleeve pipe 4, pad 8 is the T shape structure that is become by the radial ringed flange that cylindrical section 3 and one end are provided with, and pad is fixed on the sleeve pipe 4 by its cylindrical section 3 plug-in mountings, and cylindrical section 3 and 4 of sleeve pipes are interference fit.The internal diameter of pad 8 is slightly larger than the internal diameter of tapering nut 5, when being screwed into when treating loading screw 1, makes and treats that loading screw 1 just can pass, and prevent to treat that loading screw 1 rocks, and plays effect stable and guiding; The root of guiding groove 12 is provided with stress relief hole 7, is used for discharging when tapering nut 5 enters in the sleeve pipe 4 opening the stress that is produced by guiding groove 12.Surface near guiding groove 12 on the sleeve pipe 4 also is provided with anti-skidding reticulate pattern 13, and its other end surface also can be provided with corresponding anti-skidding reticulate pattern according to demand.
During use, as shown in Figure 2, only hexagon nut 2 need be inserted in the pad 8, will treat that again loading screw 1 passes hexagon nut 2 backs and inserts in the sleeve pipe 4, and get final product with stubborn mutually the closing of tapering nut 5.
The utility model can also be arbitrarily and hex head bolt, harness cord screw rod, hook bolt etc. combine, very easy to use.
