Specific embodiment
With reference to the accompanying drawings, the utility model is further described below.
The utility model discloses a kind of anchor bolts detachably reused, and are different from the prior art and are：Including spiral shell
Bolt 1, the shank of bolt outer wall of 1 one end of bolt are equipped with external screw thread, a washer 2, bolt are socketed on the shank of bolt of 1 other end of bolt
A step expansion sleeve 3 is socketed on 1 shank of bolt, a type conical bench nut 4, step are screwed with outside the shank of bolt of 1 one end of bolt
Expansion sleeve 3 is on the shank of bolt between type conical bench nut 4 and washer 2, and type conical bench nut 4 is by being located at the circular cone of one end
Mesa-shaped tube body 5 and the straight tube-like tube body 6 positioned at the other end are formed, and one end of straight tube-like tube body 6 and circular cone shape tube body 5 are another
End is in integral structure, and the interior cavity wall of straight tube-like tube body 6 is equipped with the internal thread coordinated with above-mentioned external screw thread, straight tube-like tube body 6
The other end is located in the tube body of above-mentioned 3 one end of step expansion sleeve, and step expansion sleeve 3 offers on the casing wall of one end
Cross groove milling 7 forms at the outer rim of above-mentioned 6 other end of straight tube-like tube body and raised is outward affiliated to step 8, step expansion sleeve
3 inner wall is equipped with the above-mentioned reverse limit step 9 for being affiliated to the cooperation of step 8, the interior cavity wall upper edge of step expansion sleeve 3
Step expansion sleeve 3, which moves towards to be formed, is affiliated to step sliding groove 15, and above-mentioned step 8 of being affiliated to is being affiliated to front and rear cunning in step sliding groove 15
It is dynamic.
In the specific implementation, the step expansion sleeve 3 offers clamp hole 10 on the tube wall of the other end.
In the specific implementation, the step expansion sleeve 3 forms several anti-skidding kerves of circle on the tube wall of one end
11。
In the specific implementation.1 other end of bolt forms hexagonal bolt head 12.
In the specific implementation, one end diameter of circular cone shape tube body 5 is more than the diameter of the other end, circular cone shape tube body 5
One end diameter is more than 3 one end diameter of step expansion sleeve, and circular arc chamfering face 13 is formed at the outer rim of 5 one end of circular cone shape tube body,
Circular cone shape tube body one end outer wall forms oblique slope surface 14 to circular cone shape tube body other end outer wall.
In the specific implementation, thickness will be done as possible by being affiliated to the thickness of tube wall at step, be not destroyed and become when being pulled out with guarantee
Shape.
