Abstract
The utility model relates to screw field, particularly relate to a kind of swell fixture, comprise screw, rate taper nut, be sheathed on tapered expansion cover outside rate taper nut, described tapered expansion is overlapped the inner and is offered several notch, the conical surface of described rate taper nut is provided with block, described block is arranged in notch, owing to being provided with said structure, and the utility model convenient disassembly, can reuse, improve bearing capacity, reduce user cost, 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 swell fixture.
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 swell fixture, and this swell fixture can be reused, and bearing capacity is high, and the installation that can be used for stone slab is fixed.
A kind of swell fixture, comprise screw, rate taper nut, be sheathed on tapered expansion cover outside rate taper nut, described tapered expansion is overlapped the inner and is offered several notch, and the conical surface of described rate taper nut is provided with block, and described block is arranged in notch.
The tapering of described rate taper nut is greater than the tapering of tapered expansion cover inner conical surface, and described depth of rebate is greater than the height of block.
Described screw is counterbore screw, and described tapered expansion cover is in petal-shaped, and described notch is interior narrow outer wide.
Owing to being provided with said structure, the utility model convenient disassembly, can reuse, improve bearing capacity, and reduce user cost, easy for installation, the installation that can be used for stone slab is fixed.
Accompanying drawing explanation
Fig. 1 is the structure dissection schematic diagram of a kind of swell fixture of the utility model.
Fig. 2 is the structural representation of rate taper nut.
Fig. 3 is the structural representation of tapered expansion cover.
Fig. 4 is the using state reference drawing of a kind of swell fixture of the utility model.
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 swell fixture, comprise screw 1, rate taper nut 2, be sheathed on outside rate taper nut 2 tapered expansion cover 3, described tapered expansion is overlapped 3 the inners and is offered several notch 31, the conical surface of described rate taper nut 2 is provided with block 21, and described block 21 is arranged in notch 31, prevents rate taper nut 2 from dallying, the tapering of described rate taper nut is greater than the tapering of tapered expansion cover inner conical surface, and described depth of rebate is greater than the height of block.Described screw 1 is counterbore screw, and described tapered expansion cover is in petal-shaped, and described notch is interior narrow outer wide.During use, tapered expansion cover 3 and rate taper nut 2 are placed in the button hole of stone slab 4 by special device by swell fixture, tighten counterbore screw rate taper nut 2, rate taper nut 2 walks toward outside and tapered expansion is overlapped 3 motionless, tapered expansion overlaps 3 distendings, make the whole hole of its turgor, with this, stone slab 4 is fixed on suspension member 5.
