[specific embodiment]
Refering to fig. 1 to Fig. 6, a kind of Fast Installation type expansion bolt of the present invention, including casing 1 and bolt 2, the bolt 2
Including screw rod 22 and positioned at 22 both ends of screw rod screw head 21 and rise first 23, it is described rise first 23 as reverse frustoconic, it is described to rise first 23
Outer surface is equipped with the first grooving of several annulars, forms the first platform 231, the casing 1 between first grooving
Perforation is equipped with through-hole in sleeve body 12 including bottom plate 11 and positioned at 11 bottom of bottom plate, the bottom plate 11 and sleeve body 12
13, the through-hole 13 includes the first rank hole 131 and second-order hole 132, and first rank hole 131 is the spiral shell being adapted with screw rod 22
Pit and diameter are greater than second-order hole 132, and the inner wall in the second-order hole 132 is equipped with annular corresponding with the first grooving
Second grooving, forms the second platform 1321 between second grooving, and the lower end of described sleeve pipe ontology 12 is equipped with several extensions
To the third grooving 121 through tube wall of bottom end, described sleeve pipe ontology 12 is hexagonal cylindricality, the bottom plate 11 and sleeve body
12 are structure as a whole, and the outer diameter of the bottom plate 11 is greater than the outer diameter of described sleeve pipe ontology 12, and the bottom surface of the bottom plate 11 is surround
Sleeve body 12 be equipped with several spines 111, the screw head 21, screw rod 22 and rising first 23 is structure as a whole, the head that rises
The outer diameter at 23 tops is identical as the diameter of screw rod 22, and the outer diameter of first 23 bottom of rising is slightly larger than the diameter in second-order hole 132, institute
The start position for stating third grooving 121 is lower than the junction in the first rank hole 131 and second-order hole 132, first grooving and the
The retaining direction of two groovings is opposite with the screw-in direction of 2 sleeve pipe 1 of bolt.
The course of work of the present invention:
A kind of Fast Installation type expansion bolt of the present invention during the work time, firstly, by casing 2 to have third grooving
It is then, the through-hole alignment of part to be fixed is preset in the preset holes of 121 one end direction insertion ground directed downwardly or metope
Hole, then be directly inserted into bolt 1 into the through-hole 13 of casing 2 to be equipped with the first 23 one end direction directed downwardly of rising.With bolt 1
Precession, rising first 23 gradually screws in the second-order hole 132 of casing 2 and makes casing 2 along the gradually spreading of third grooving 121.
The present invention passes through the cylindrical sleeve body of hexagonal and the bottom plate that spine is provided in sleeve body, avoids casing
As the precession of bolt is spinned in hole, the tightness of expansion bolt ensure that, make casing along second by the precession for the head that rises
