Abstract
The utility model relates to screw field, particularly relate to a kind of stacked EXPANSION ANCHOR BOLTS, comprise T-shaped bolt, the nut be located on T-shaped bolt, the several frustum expansion sleeves be sheathed on T-shaped bolt, be located at spacer ring between frustum expansion sleeve, be located at cascade nylon sleeve outside frustum expansion sleeve, owing to being provided with said structure, it is strong and stable that this EXPANSION ANCHOR BOLTS installs fastening force, Gu Liqiang, and installation precision is high, can not swing, easy for installation, the installation that can be used for stone slab is fixed.
Description
Technical field
The utility model relates to screw field, particularly relates to a kind of stacked EXPANSION ANCHOR BOLTS.
Background technique
Swell fixture is for object is fixed on body of wall or plate body, and its principle utilizes wedge shape gradient to impel expansion, reaches fixing effect.Existing swell fixture, be made up of screw, nut, expansion sleeve, screw has cone-shaped end, expansion sleeve one end has narrow slit notch, first on wall or plate body, mounting hole is bored during use, then expansion tube and screw rod are thrown in mounting hole, then equipment mounting hole is enclosed within fall the head threads end of bar, finally to screw on nut at rod head threaded end, make equipment be fixed on wall, in the process of fastening nut, screw rod walks toward outside and expansion tube is motionless, the round table-like expansion tube distending of screw rod tail, makes the whole hole of its turgor, reaches fixing with this; Swell fixture of the prior art is because the expansion tube that the diameter in the hole beaten on stone slab has the degree of error, nut screwing clamping difference etc. reason to there will be swell fixture can not expand completely, making can be more much smaller than what estimate with active force between the walls under tight condition, thus cause the stone slab be arranged on suspension member to be easy to the situation occurring loosening, well can not realize the effect of fixing.Due to structural reason dismounting trouble, can not recycle; And bearing capacity is little.
Summary of the invention
The purpose of this utility model is to provide a kind of stacked EXPANSION ANCHOR BOLTS, and this EXPANSION ANCHOR BOLTS fastening force is strong, and installation precision is high.
A kind of stacked EXPANSION ANCHOR BOLTS, comprises T-shaped bolt, the nut be located on T-shaped bolt, the several frustum expansion sleeves be sheathed on T-shaped bolt, is located at spacer ring between frustum expansion sleeve, is located at cascade nylon sleeve outside frustum expansion sleeve.
Going to the bottom of described frustum expansion sleeve offers several notch, form several pieces to hack, described cascade nylon sleeve the inner is provided with bulge loop, the external diameter of described bulge loop is equal with the external diameter of spacer ring, the external diameter of described cascade nylon sleeve is roughly the same with mounting hole, cascade nylon sleeve sinks in mounting hole, the external diameter of going to the bottom of described frustum expansion sleeve is greater than the external diameter of cascade nylon sleeve, during installation, frustum expansion sleeve is bent outwardly for hacking of fulcrum frustum expansion sleeve with spacer ring and bulge loop outer, is headed in mounting hole by cascade nylon sleeve.
Owing to being provided with said structure, it is strong and stable that this EXPANSION ANCHOR BOLTS installs fastening force, Gu Liqiang, and installation precision is high, can not swing, easy for installation, and the installation that can be used for stone slab is fixed.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of stacked EXPANSION ANCHOR BOLTS, comprises T-shaped bolt 1, the nut 2 be located on T-shaped bolt 1, the several frustum expansion sleeves 3 be sheathed on T-shaped bolt 1, is located at spacer ring 4 between frustum expansion sleeve 3, is located at cascade nylon sleeve 5 outside frustum expansion sleeve 3.Described going to the bottom of cover of frustum expansion 3 offer several notch 31, form several pieces and hack 32, described cascade nylon sleeve 5 the inner is provided with bulge loop 51, the external diameter of described bulge loop 51 is equal with the external diameter of spacer ring 4, the external diameter of described cascade nylon sleeve 5 is roughly the same with mounting hole 6, cascade nylon sleeve 5 sinks in mounting hole 6, the external diameter of going to the bottom of described frustum expansion sleeve 3 is greater than the external diameter of cascade nylon sleeve 5, during installation, frustum expansion sleeve 3 is bent outwardly to be fulcrum frustum expansion sleeve 3 hack 32 spacer ring 4 and bulge loop 51 outer, head in mounting hole 6 by cascade nylon jacket 5, spacer ring 4 also makes frustum expansion 3 be spaced apart, prevent frustum from expanding 3 superimposed, increase the bending force of frustum expansion sleeve 3 outer, and EXPANSION ANCHOR BOLTS is placed in mounting hole.During use, to fold in EXPANSION ANCHOR BOLTS press-in mounting hole 6, T-shaped bolt 1 outer end is through suspension member 7, screw on nut 2, T-shaped bolt 1 is outwards walked, and frustum expansion sleeve 3 outer is stuck in mounting hole inwall again, frustum expansion sleeve 3 is column shape distending under the effect of T-shaped bolt 1, make the whole hole of its turgor, suspension member 7 is fixed on body of wall 8, then stone slab 4 is fixed on suspension member 7.
