Specific embodiment
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 device as shown in FIG. 1 to FIG. 3, for being plugged in the porthole of construction wall；The expanding screw
Spike devices include a screw 1, sleeve 2, nut 3 and lantern ring 4；One end of the screw 1 is provided with one and has first tiltedly
The ring-shaped step head 5 in face, the other end is threadedly coupled after passing through sleeve 2 and nut 3 with nut 3, towards ring-shaped step head in sleeve 2
To be provided with 8 with sleeve 2 be uniformly distributed the first notch 6 of axle center annular for one end, form one between two neighboring first notch 6
First expansion piece 7, first expansion piece 7 are contacted with the first inclined-plane 14 of ring-shaped step head 5；
The periphery of the screw 1 is provided with the uniformly distributed and raised baffle 8 of 8 annulars, the periphery setting of the sleeve 2
The periphery of the perforation 9 for having 8 annulars uniformly distributed and coaxial baffle ring 10, the baffle ring 10 is the second inclined-plane 11, and the baffle 8 is worn
It crosses perforation 9 to contact with lantern ring 4, one end in the lantern ring 4 towards nut direction is provided with 8 and is evenly distributed with sleeve 2 for axle center annular
The second notch 12, form second expansion piece 13 between two neighboring second notch 12, second expansion piece 13 and the
The cooperation contact of two inclined-planes 11, the baffle 8 contact after passing through perforation 9 with lantern ring 4.
When installation, swell fixture device is inserted into porthole, then screw 1 is displaced outwardly, the ring-shaped step head 5
