Such as, Chinese patent discloses a kind of expansion bolt, application number
[201220561622.8], its expanding screw that only just can take out completely from one end of bolt hole
Bolt, described expansion bolt includes screw rod, expansion sleeve and nut, packing ring, one end of screw rod
For the external thread section with nut screw connection, the other end of screw rod is and expansion sleeve cone match
Round platform, is provided with sleeve pipe at screw jacket, and the two ends of sleeve pipe bear against in packing ring and expansion
Putting, during expansion sleeve distending, the end face of expansion sleeve is beyond the end face of screw rod, and its connection can
Lean on, detachably, be especially suitable for being rigidly connected temporarily.
Although above-mentioned scheme has many advantages, but, this bolt its most at least
There is techniques below problem: after expansion sleeve is extruded expansion, its outer wall is smooth table
Face, or there is the caducous technical problem of appearance.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that a kind of design is more reasonable,
It can be avoided that the modified form expansion bolt assembly come off.
For reaching above-mentioned purpose, this utility model have employed following technical proposal: this improvement
Type expansion bolt assembly includes bolt, is cased with pad, expansion tube and cone on bolt successively
Shape nut, expansion tube one end is resisted against on pad, and the other end acts on tapered cup nut,
In the middle part of expansion tube, it is provided with the bar hole of some even circumferentials distribution, acts at expansion tube
One end on tapered cup nut has fluting and the phase that some with described bar hole connects one by one
Form deformation sheet between two adjacent flutings, be respectively provided with arc every deformation sheet outer end
Lug, is respectively provided with the first outwardly reinforcement projection on each arc lug,
It is convex that one end that every deformation sheet is provided with arc lug also has the second outwardly reinforcement
Rise, the height that the second described reinforcement height of projection is protruding more than the first reinforcement.
