Description
Technical field
What be the utility model is related to is two-way setscrew.
Background technology
The now iron swell fixture various types of in the market, but be all unidirectionally to compress ringfeder using taper so as to fix article,
Because being unidirectional fixation, so as to which fixed stability and intensity are had a greatly reduced quality, particularly fixation is not static article（Such as sky
Tune, electric fan etc.）Thus have certain shortcoming, specially the axial direction of screw, radially can vibration, after causing over time
Produce and loosen and drop.
200620142494.8 a kind of expansion screw of kinds of point mode is disclosed.Expanded using two point on expansion sleeve, solve expansion
Set is fixed on the strength problem in wall hole.But because the axial direction of its body of rod is to be fixed, expansion sleeve is also very stable
Two point is fixed in hole, but what the body of rod still can radially rock.Therefore over time after, still can produce loosening and from
Dropped in hole.
Therefore need to design the setscrew that a kind of screw rod is all rigidly mounted to axial direction, radially in wall hole.
Utility model content
In view of this, in order to solve the above problems, a kind of this new two-way setscrew of offer.
Two-way setscrew, including a screwed body of rod, it is characterized in that：Screw thread one end on the body of rod is just
It is reverse thread to screw thread, the other end, that end of forward screw thread is distributed with the body of rod, is cased with left tooth ringfeder, its inner surface screw thread
Matched with forward screw thread, that end that reverse thread is distributed with is cased with right tooth ringfeder, its inner surface screw thread and is matched with reverse thread；
The left tooth ringfeder is similar with right tooth ringfeder structure, and for cylindrical shape, screw thread is distributed with inner surface, and head end surfaces externally and internally flushes,
The drum surface of aft end inner surface band taper, left tooth ringfeder and right tooth ringfeder is provided with groove vertically, and the groove penetrates inside and outside
Surface；The groove of left tooth ringfeder extends to the left end of left tooth ringfeder cylinder, i.e., the afterbody of left tooth ringfeder since drum surface middle part
Open breach is formed on end bottom, and the groove of right tooth ringfeder extends to the right-hand member of right tooth ringfeder cylinder since drum surface middle part,
Open breach is formed on i.e. right tooth ringfeder aft end bottom；Be additionally provided with 2 on the body of rod and the body of rod is integrated, it is with taper
Step, the scalene cone matching of left part step, the oblique cone of right tooth ringfeder aft end on the scalene cone and the body of rod of left tooth ringfeder aft end
The scalene cone matching of right part step on face and the body of rod；One section of body of rod is additionally provided with behind the right part step or left part step.
Further, either left part step for welding or is riveted on the body of rod right part step.
Further, the groove of left tooth ringfeder and right tooth ringfeder afterbody is symmetrical 2-8 bars.
Further, the body of rod tail end behind the right part step or left part step is arranged to square, to facilitate with tiger
The pincers rotation body of rod.
Further, the screw thread on the screw thread on the body of rod, left tooth ringfeder and right tooth ringfeder uses fine thread, is
Increase self-lock force.
Further, after left tooth ringfeder and right tooth ringfeder are set on the body of rod, the head end of left tooth ringfeder and right tooth ringfeder
It is brought into tight contact with each other.
It is put into after two-way setscrew is assembled during use in the hole accomplished fluently on wall, the rotation body of rod makes left tooth and the right side
The ringfeder of tooth moves to both sides, because the ringfeder afterbody fluting and inner surface of left tooth and right tooth be scalene cone, the scalene cone with
The scalene cone of step is mutually after extruding, the ringfeder afterbody of left tooth and right tooth along at fluting to radial dilatation.It is rotated further the body of rod,
The ringfeder of left tooth and right tooth continues to move to both sides, the ringfeder afterbody of left tooth and right tooth continue along fluting to radial dilatation until
Wall hole is fully supported, now the body of rod can not again rotate.
A kind of expansion screw of kinds of point mode disclosed in 200620142494.8, because the body of rod and nut are matched using screw thread, spiral shell
Female rigidity is again very big, thus no matter the pressure between expansion sleeve and hole（Expansion sleeve is by this pressure fixing in hole）Have more
Greatly, this pressure will not also allow nut to produce radial forces to the body of rod, thus in the hole after, the body of rod is in radial load
Under effect, vibration can be produced.
In the technical scheme of the application, step is advance and bar is integrally formed or welds together.Therefore step is fixed,
It is equal to fix screw rod.After by being arranged on upper type in hole, the inwall in hole produces pressure to expansion sleeve, causes swollen
Expansion set tail end produces pressure to step, i.e. hole inwall produces radial forces to screw rod.Now, the inwall in hole, step, one is formed
Individual entirety, so as to which screw rod can not produce vibration in radial direction.
Compared to the prior art, this programme is by rotary screw, drives left and right facing to promote in the lateral direction, so that will
Screw rod two point is fixed in hole.Screw rod is radially, axially all well fixed.This programme is using two independent mutually teeth
Set, fixes the radial and axial of screw rod respectively, above advantage, is all not have disclosed in the prior art, has and create
Property.
