Abstract
The utility model discloses a fastening piece for anchoring, which comprises a screw rod. The utility model is characterized by further comprising an expansion piece, a sleeve cylinder and a nut which are sequentially mounted on the screw rod. Besides, one end of the screw rod is equipped with an expansion end which is in round cone shape, the expansion piece is in round cone shape, the diameter of the expansion piece close to the sleeve cylinder is smaller than that close to the expansion end, and the expansion piece is equipped with stress eliminating slots. Compared with the prior art, the utility model has the advantage of reliable connection.
Description
[technical field]
The utility model relates to a kind of securing member, relates in particular to a kind of grappling securing member in the fragile material thin plates such as stone material that is applied to.
[background technology]
At present, for object is fixed on the wall, designed a kind of expansion bolt, purpose is with bolt on the wall, and exposes outside one section screwed screw rod at body of wall, by nut object is fixed on the screw rod.This expansion bolt is provided with a sleeve, described sleeve is provided with the slit, hole on the wall during installation, expansion bolt is put into the hole, and sleeve shortens when tighting a bolt, and is extruded to strut, internal surface of hole is formed expansion tension, simultaneously screw rod is formed radially pressure, thereby this screw rod is stuck in the hole, reach fixing effect.By screw rod pressure radially being difficult to guarantee screw rod does not endwisely slip, if by screw rod pressure is radially guaranteed that screw rod does not endwisely slip, then must guarantee very big to screw rod pressure radially, be applied on bigger body of wall that can bear bigger internal stress of some thickness or the plate all right, but this kind expansion bolt is applied in the fragile material thin plates such as stone material, pottery, easily because expansion tension causes crack more greatly, the aperture is enlarged, internal surface of hole diminishes to the pressure of screw rod, screw rod may endwisely slip, and it is unreliable to connect.
[utility model content]
In order to overcome existing above-mentioned defective, the utility model provides a kind of grappling securing member.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of grappling securing member, comprise screw rod, also comprise the expansion piece, sleeve and the nut that are installed in successively on the screw rod, described screw rod one end is provided with expanding end, described expanding end is a circular cone shape, described expansion piece is the pipe shape, and the caliber of the close sleeve of described expansion piece is less than its caliber near expanding end, and described expansion piece is provided with stress and eliminates seam.
Length on described stress elimination is sewn on axially is greater than 50% of described expansion piece height.
Described stress is eliminated and is stitched to rare two.
Described stress is eliminated to be sewed with regularly and is distributed on the expansion piece.
Described stress is eliminated seam expander is divided into the arc plates that at least two tops connect, and described plates comprise the trapezoid plates and fall trapezoidal plates, described trapezoid plates and described to fall trapezoidal plates spaced.
Be provided with pad between described nut and the described sleeve.
Compared with prior art, the beneficial effects of the utility model are: the expansion piece pressurized enters the reaming of bottom, hole during grappling, when expansion piece expands in the bottom, hole when opening, expansion piece is stuck in the reaming, this moment, expansion piece was very little to internal surface of hole expansion tension radially, mainly be that expansion piece is bigger to the axial compression of reaming, and rely on expansion piece to make screw rod that axial slip not take place to the axial compression of screw rod, and the trapezoid plates that are provided with separately on the expansion piece and the trapezoidal plates that fall, expansion piece is expanded equably along expanding end preferably to be opened, make expansion piece and expanding end even, contact fully, guarantee that expansion piece has uniform axial compression to expanding end, guarantee to connect reliable.

[specific embodiment]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: as Fig. 1, Fig. 2 and shown in Figure 3, a kind of grappling securing member, comprise screw rod 6, also comprise the expansion piece 2, sleeve 3 and the nut 5 that are installed in successively on the screw rod 6, described screw rod 6 one ends are provided with expanding end 1, described expanding end 1 is a circular cone shape, described expansion piece 2 is the pipe shape, pipe thickness is even, the caliber of described expansion piece 2 close sleeves 3 is less than its caliber near expanding end, and described expansion piece 2 is provided with stress and eliminates seam 7.
The inner surface of described expansion piece 2 is a taper seat, can make expansion piece 2 evenly stressed when expanding end 1 expands, and expansion piece 2 is better fitted with expanding end 1, guarantee expansion finish after expansion piece 2 be close to expanding end 1.
As shown in Figure 2, described stress is eliminated seam 7 length in the axial direction greater than 50% of described expansion piece 2 height, so is provided with and can eliminates the swelling stress of expansion piece 2 when expanding to the full extent, reduces to install the impact force that needs.
As shown in Figure 2, described stress is eliminated the projection straight line of seam 7 and the axis of described screw rod 6 acutangulates, and the projection straight line that adjacent two described stress are eliminated seam 7 is mutually acute angle.
As shown in Figure 4, described stress elimination seam 7 has two at least.
As shown in Figure 4, described stress elimination seam 7 is distributed on the expansion piece 2 regularly.
As shown in Figure 4, described stress is eliminated seam 7 expander 2 is divided into the arc plates that at least two tops connect, described plates comprise the trapezoid plates 22 and the trapezoidal plates 21 that fall, described trapezoid plates 22 are spaced with the described trapezoidal plates 21 that fall, described trapezoid plates 22 launch similar to the trapezoid shape, describedly fall trapezoidal plates 21 and launch to trapezoidal shape is similar.
With the trapezoid plates 22 and the trapezoidal plates 21 adjacent settings of falling, the centre is eliminated seam 7 with described stress and is separated, the trapezoid plates 22 and the trapezoidal plates 21 that fall can well open along expanding end, stress is eliminated seam 7 and has well been eliminated the stress of expansion piece 2 when opening, expansion piece 2 is evenly opened along expanding end 1, and gross distortion can not take place in expansion piece 2 in the process of opening, if expansion piece 2 distortion seriously may certain a bit on many places overlapping, cause stress to concentrate, influence the reliability that screw rod 6 connects, distortion seriously also may cause expansion piece 2 fractures, influences the reliability that screw rod 6 connects.
As shown in Figure 1, be connected with pad 4 between described nut 5 and the described sleeve 3.
Need carry out the place boring of grappling at fragile material thin plates such as stone material, potteries, and in the reaming of the bottom in hole, screw rod 6 is put into the hole together with expansion piece 2 and sleeve 3, in the bottom reaming of sleeve 3 with expansion piece 2 hammer hand-holes, reach grappling, the object that will need to fix with pad 4 and nut 5 is fixed on the screw rod 6.
