Description
Technical field
The utility model belongs to building fastener areas, specifically, more particularly to a kind of stable type swell fixture.
Background technology
Traditional expanding screw nail piece, some are used for connecting building wall and the fastener for connecting glass curtain.The stabilization
Type swell fixture includes screw, sleeve and nut, is rotated by nut and screw movement, screw is driven to be driven while mobile
Sleeve expansion, to make sleeve withstand porthole to achieve a fixed connection, since nut can drive screw and set when rotation
Cylinder rotation to make sleeve expansion, therefore installs inconvenience, and installation is insecure.
Utility model content
(1) technical problems to be solved
The technical problems to be solved in the utility model is that swell fixture to be solved leads to the problem of rotation.
(2) technical solution
In order to solve the above technical problems, technical solution used by the utility model is：A kind of stable type swell fixture is used
In being plugged in the porthole of construction wall；Include a screw, sleeve, nut and cement steel nail；One end of the screw is set
It sets there are one with bevelled ring-shaped step head, the other end is connect after passing through sleeve and nut with nut thread, direction in sleeve
One end of ring-shaped step head is provided with several using the sleeve notch uniformly distributed as axle center annular, and one is formed between two neighboring notch
A expansion piece, the contact of incline plane of the expansion piece and ring-shaped step head, the screw include that there are one axis hole, the cement steel nails
One end pass through and axis hole and hammer into wall；The cross section of the axis hole and cement steel nail is polygon.
In above-mentioned stable type swell fixture, the cross section of the axis hole and cement steel nail is hexagon.
In above-mentioned stable type swell fixture, the periphery of the screw and sleeve is respectively arranged with first through hole and second
The both sides of through-hole, the first through hole are connected to axis hole and the second through-hole respectively, and second through-hole is connected to porthole.
In above-mentioned stable type swell fixture, first through hole annular on the periphery of screw is uniformly distributed, and described second
Through-hole annular on sleeve is uniformly distributed.
In above-mentioned stable type swell fixture, the material of the cement steel nail is 40# -45# medium carbon steel.
(3) advantageous effect
The stable type swell fixture of the utility model, cement steel nail follow closely in wall, by polygonized structure make screw without
Method rotates, and to screw be driven to rotate when tightening nut, therefore avoid screw makes expansion piece can not because of rotation
The problem of expansion, therefore assemble very convenient and again secured.
Description of the drawings
Fig. 1 is that the stable type swell fixture 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 cement steel nail, 5 be ring-shaped step head, 6 be notch, 7 is expansion
Piece, 8 be axis hole, 9 be first through hole, 10 be the second through-hole, 20 be porthole.
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 stable type swell fixture as depicted in figs. 1 and 2, for being plugged in the porthole 20 of construction wall；Including
It is the cement steel nail 4 of 40# -45# medium carbon steel to have a screw 1, sleeve 2, nut 3 and material；One end of the screw 1 is arranged
There are one with bevelled ring-shaped step head 5, the other end is threadedly coupled after passing through sleeve 2 and nut 3 with nut 3, court in sleeve 2
Several are provided with sleeve 2 for the uniformly distributed notch 6 of axle center annular, between two neighboring notch 6 to one end of ring-shaped step head 5
One expansion piece 7 of formation, the contact of incline plane of the expansion piece 7 and ring-shaped step head 5, the axis hole 8 comprising there are one of the screw 1,
One end of the cement steel nail 4 passes through axis hole 8 and hammers into wall；The cross section of the axis hole 8 and cement steel nail 4 is polygon
Shape.
Specifically, the cross section of axis hole 8 and cement steel nail 4 is hexagon.
The periphery of the screw 1 and sleeve 2 is respectively arranged with first through hole 9 and the second through-hole 10, the first through hole 9
Both sides be connected to respectively with axis hole 8 and the second through-hole 10, second through-hole is connected to porthole 20.
Above-mentioned first through hole 9 annular on the periphery of screw 1 is uniformly distributed, and second through-hole 10 is annular on sleeve 2
It is uniformly distributed.
When assembly, first screw and sleeve 2 are sent to together in porthole 20, the cement steel nail 4 passes through axis hole 8 and hammers into
Into wall, nut is then tightened, since the cross section of axis hole 8 and cement steel nail 4 is polygon, so cement steel nail 4 can
To limit the rotation of screw 1, nut will not drive screw 1 when tightening, to not interfere with the movement of ring-shaped step head 5,
Therefore expansion piece 7 can normal expansion, so do not interfere with the connection effect of swell fixture and wall, assembly is more very convenient.Most
After cement steel nail 4 can be taken out, glue is injected in the axis hole 8, the glue is distributed along first through hole 9 and the second through-hole 10
In to the gap of porthole 20 and swell fixture, so connection is more secured.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
