In above-mentioned swell fixture mechanism, the shape of the double wedge is triangle.
Further include shackle member in above-mentioned swell fixture mechanism, the ring-shaped step head include there are one and ring-shaped step
The vertical through-hole of head axial line, the interior setting of the through-hole is there are one shaft, and one end of the ring-shaped step head is provided with torsional spring, institute
The intermediate ends for stating torsional spring are socketed in shaft, and both ends contact after passing through through-hole with the hole wall of porthole.
In above-mentioned swell fixture mechanism, the shape of the torsional spring is V-type, and the opening direction of V-type is towards nut direction.
In above-mentioned swell fixture mechanism, the axial direction of the through-hole is provided at both ends with a block, and the block setting exists
The rear side at torsional spring both ends, and contacted with torsional spring.
(3) advantageous effect
The swell fixture mechanism of the utility model, can be embedded into the hole wall of porthole by double wedge, improve expansion in this way
The contact force of piece and porthole, more secured to make swell fixture mechanism connect with porthole, in addition double wedge is rolled over by expansion piece
It is curved to form, so making is very convenient, without being formed by die casting, to reduce cost.
Description of the drawings
Fig. 1 is that the swell fixture mechanism of the utility model is mounted on the structural schematic diagram on construction wall；
Fig. 2 is the sectional view of A-A in Fig. 1；
1 it is screw in figure, 2 be sleeve, 3 be nut, 4 be ring-shaped step head, 5 be notch, 6 be expansion piece, 7 is bending
End, 8 be double wedge, 9 be through-hole, 10 be porthole, 11 be shaft, 12 be torsional spring, 13 be block.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
A kind of swell fixture mechanism as depicted in figs. 1 and 2, for being plugged in the porthole 10 of construction wall.It is described swollen
Swollen screw mechanism includes a screw 1, sleeve 2 and nut 3；There are one with bevelled ring for one end setting of the screw 1
Shape step head 4, the other end is threadedly coupled after passing through sleeve 2 and nut 3 with nut 3, towards the one of ring-shaped step head 4 in sleeve 2
It is the uniformly distributed notch 5 of axle center annular that end, which is provided with several with sleeve 2, and an expansion piece 6 is formed between two neighboring notch 5,
One end of the contact of incline plane of the expansion piece 6 and ring-shaped step head 4, the expansion piece towards 1 sagittal plane direction bending of screw and is formed
Bending end 7 is provided with the double wedge 8 that can be contacted with the hole wall of porthole 10 at the top of the bending end, can be embedded by double wedge 8
In the hole wall of porthole 10, the contact force of expansion piece 6 and porthole 10 is improved in this way, to make swell fixture mechanism and porthole 10 connect
More securely, in addition double wedge 8 is formed by expansion piece bending, so making is very convenient, without being formed by die casting,
To reduce cost.
The shape of above-mentioned double wedge 8 is triangle.
The utility model further includes shackle member, and the ring-shaped step head 4 includes that there are one hang down with 4 axial line of ring-shaped step head
Straight through-hole 9, there are one shafts 11 for the interior setting of the through-hole 9, and one end of the ring-shaped step head 4 is provided with torsional spring 12, described
