Description
Technical field
This utility model is related to a kind of back of the body bolt, especially a kind of detachable back for being mainly used in stone material finishing processing industry
Bolt, belongs to stone material finishing processing handware technical field.
Background technology
At present, detachable back-bolt commonly used in stone material finishing processing industry, but according to the applicant understood, using existing
Detachable back-bolt, when back of the body bolt jacking drilling and being allowed to expand, it occur frequently that crossing top phenomenon, as a result causes stone material by back of the body bolt top
Wear and damage.Occurred push up phenomenon mainly due to back of the body bolt jacking drilling in distance cannot obtain limit caused by.
Content of the invention
The purpose of this utility model is：For the shortcoming that above prior art is present, propose a kind of simple structure and
The detachable back-bolt for pushing up and destroying stone material can be prevented.
In order to reach object above, detachable back-bolt of the present utility model includes making female anchor set and is formed with outer spiral shell
Stricture of vagina the anchor pole with anchor set threaded engagement, anchor are set on one end of anchor pole, be formed with least one and crack on the anchor set bottom,
Be improved by, anchor set is outer to be cased with anti-vibration sleeve and crash roll, and anti-vibration sleeve is fixedly connected with crash roll, the free end of the crash roll to
Interior curling is simultaneously connected to the root that anchor covers.
When using, when anchor pole is tightened in place, crash roll is contacted with metope and gives a buffering this utility model, with
When due to crimp crash roll the hole that anchor set is stretched into all is covered, its by anchor set completely cut off with the external world, extend back of the body bolt
Service life.
The perfect of detachable back-bolt of the present utility model is to arrange hex bolts, the length root of anchor pole on described anchor pole
Some scale lengths are made in advance according to the depth in institute's diamond material hole.So when using, from the removable of corresponding drilling depth
Back of the body bolt, by anchor set and anchor pole head into drilling and on fasten back of the body bolt, after jacking certain distance, hex bolts and anti-vibration sleeve and shockproof
Pad is in close contact, and then covers close contact with anchor and stop that anchor pole continues jacking, so as to avoid anchor pole from causing stone because crossing screw-in
The destruction of material.
Further improving for detachable back-bolt of the present utility model is that the bottom of the anchor set arranges outside convex edge
Edge.
Further improving for detachable back-bolt of the present utility model is that the other end of the anchor pole is formed with hexagonal spanner or interior
Hexagon ring, so that carry out precession from spanner or inner hexagon spanner to anchor pole according to practical situation.

Specific embodiment
This utility model is described in further detail with reference to Figure of description：
Embodiment one：
The detachable back-bolt of the present embodiment is as shown in figure 1, main body includes that anchor set 1 and anchor pole 2, anchor set 1 are formed with female thread, anchor
Cover to be formed with the side wall of 1 bottom and crack 3, the bottom of anchor set 1 is formed with convex edge 5 simultaneously；Anchor pole 2 is formed with external screw thread, its one end
Spanner 6 is formed with, the other end is screwed in anchor set 1, arranges hex bolts 4 thereon；The cross section of spanner 6 is hexagon；Anchor pole 2 with
Anchor covers 1 threaded engagement.The outer surface of anchor set 1 is set with anti-vibration sleeve 8, and crash roll 9, anti-vibration sleeve 8 is fixedly installed in 8 lower end of anti-vibration sleeve
On be formed with one and crack, anti-vibration sleeve 8 and crash roll 9 are all made using rubber, the free end inward curl of crash roll 9, and clamping
Root at the convex edge of anchor set 1.
Using the present embodiment detachable back-bolt when, the Kong Bingtuo for being first drilled desired depth on stone material is drilled well, then
Choose and there is the detachable back bolt assembly for being adapted to substantially anchor pole 2 with drilling depth, now anchor pole 2 is in hex bolts 4 and anti-vibration sleeve 8
Between a segment length be substantially equal to drilling depth, by anchor set 1 be formed with 5 one end of convex edge be lowered into drilling in, use spanner card
Firmly anchor pole 2 is screwed in anchor set 1 by spanner 6 expands anchor set 1.When 2 length of anchor pole for screwing in anchor set 1 is close to drilling depth, hexagonal
Anti-vibration sleeve 8 encountered by bolt 4, due to crash roll 9 because the deformation that curling is produced has arrived at the limit, prevents naturally spanner from going again
The screw-in anchor of anchor pole 2 set 1 is pulled, when anchor set 1 is screwed in so as to avoid anchor pole 2 from continuing, because the top of anchor pole 2 exceeds the convex of anchor set 1
The thin-walled of stone material drill hole is extruded behind edge 5, damages stone material.
Embodiment two：
The detachable back-bolt of the present embodiment as shown in Fig. 2 its structure is essentially identical with embodiment one, except that anchor pole
2 one end does not have spanner 6, but is formed with inner hexagonal hole 7 in the end.So, when by anchor set 1 and 2 jacking stone material of anchor pole drilling
When, anchor pole 2 is screwed in anchor set 1 by pulling insertion inner hexagonal hole 7 with interior hexagonal expands anchor set 1.
In addition to the implementation, this utility model can also have other embodiment.All employing equivalents or equivalent change
The technical scheme to be formed is changed, the protection domain of this utility model requirement is all fallen within.
