Abstract
The invention discloses a kind of double thread three-stage swell fixture component, including dilate bar, dilate nut and expansion sleeve described in expansion sleeve be socketed in and dilate on bar；Described one end for dilating bar is provided with screw thread, and the other end is provided with circular cone, dilates the middle part of bar uniformly provided with two sections of convex stupefied I；Provided with two sections of convex stupefied II being engaged with convex stupefied I inside the expansion sleeve；It is described dilate nut and be arranged on dilate and set on bar threaded one end.Described dilate is disposed with annular groove in nut bottom, the inside of annular groove is provided with internal thread；One end of the expansion sleeve is provided with annular groove with individual male, and the surface of the male is provided with external screw thread.Beneficial effects of the present invention：When inverted cone is entered inside expansion sleeve, nut be threadedly coupled by the internal thread of annular groove with the external screw thread of male so that nut forms secondary fixation and is difficult to slide, it is ensured that swell fixture component it is firm.
Description
Technical field
It is used to hang on wall the invention belongs to one kind or fixed object, more particularly to a kind of swollen screw of the three-stage of bulk expansion
Component.
Background technology
Existing swell fixture digs an elongated hole matched with the diameter and length of expansion sleeve on wall when in use, first, so
Afterwards toward being put into swell fixture component in elongated hole, and it is rotated further by nut thereon；The instant pushing tow expansion sleeve of rotation of nut is moved to the left,
When expansion sleeve touches the inverted cone of screw rod, section where the notch of expansion sleeve starts expansion, and with expansion sleeve left lateral without
Disconnected expansion, until swell fixture is fastened in wall.Existing swell fixture also has following shortcoming：Though it can on wall
By fixation, for people it is safe to use, but it cannot be unloaded when people are not required to it, unless its revealed section amputated；
Otherwise the screw rod revealed section of swell fixture continues to be deposited on wall, has both made wall out-of-flatness clean and tidy, and for fear of the daily of people
Action, while existing swell fixture is all that afterbody expansion fixed effect is not good enough, lacks a kind of swollen screw assembly of bulk expansion,
To improve fixed effect.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of convenience and dismantle, firmly install and using the swell fixture component of safety.
To solve the above problems, the technical scheme is that：A kind of double thread three-stage swell fixture component, including dilate bar,
Expansion sleeve described in dilating nut and expansion sleeve, which is socketed in, to be dilated on bar；Described one end for dilating bar is provided with screw thread, and the other end is provided with
Circular cone, dilates the middle part of bar uniformly provided with two sections of convex stupefied I；It is convex stupefied provided with two sections be engaged with convex stupefied I inside the expansion sleeve
II；It is described dilate nut and be arranged on dilate and set on bar threaded one end.Described dilate is disposed with annular groove in nut bottom, ring
The inside of shape groove is provided with internal thread；One end of the expansion sleeve is provided with annular groove with individual male, and the surface of the male is provided with
External screw thread.
Further, described dilate is provided with packing ring between nut and expansion sleeve.
Further, the expansion sleeve is uniformly provided with some tooth form non-slip process.
Beneficial effects of the present invention：Because the middle part for dilating bar is uniformly provided with and convex stupefied I provided with two sections of convex stupefied I and expansion sleeve inside
Two sections of convex stupefied II being engaged, the middle part of expansion sleeve can also expand during installation so that swell fixture bulk expansion, it is to avoid existing
There was only afterbody expansion in technology and influence the situation of fixed effect.Dilate and annular groove is disposed with nut bottom, the inside of annular groove
Provided with internal thread；One end of the expansion sleeve is provided with annular groove with individual male, and the surface of the male is provided with external screw thread.When
When inverted cone is entered inside expansion sleeve, nut is threadedly coupled by the internal thread of annular groove with the external screw thread of male so that nut
Formed secondary fixation be difficult landing, it is ensured that swell fixture component it is firm.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Embodiment
The invention will be further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of double thread three-stage swell fixture component, including dilate bar 1, dilate nut 2 and expansion sleeve 3
The expansion sleeve 3, which is socketed in, to be dilated on bar 1；Described one end for dilating bar 1 be provided with screw thread, the other end be provided with circular cone, dilate
The middle part of bar 1 is uniformly provided with two sections of convex stupefied I 1.1；The inside of expansion sleeve 3 is convex stupefied provided with two sections be engaged with convex stupefied I 1.1
II 3.1；It is described dilate nut 2 and be arranged on dilate threaded one end set on bar 1.When swell fixture is installed, is twisted and expanded with spanner
Expansion nut 2, dilates bar 1 and above carries, and circular cone dilates the afterbody of expansion sleeve 3, and convex stupefied I 1.1 and convex stupefied II 3.1 dilates expansion sleeve 3
Middle part, realize the bulk expansion of swell fixture, it is to avoid only afterbody expansion, expansion sleeve 3 non-homogeneous expansion is even in mounting hole
Situation about easily rocking so that swell fixture is more firmly mounted.
Dilate and annular groove 2.1 is disposed with the bottom surface of nut 2, the inside of annular groove 2.1 is provided with internal thread；The one of the expansion sleeve 3
End is provided with annular groove 2.1 with individual male 3.2, and the surface of the male 3.2 is provided with external screw thread.When inverted cone enters expansion
When covering 3 inside, dilate nut 2 and be threadedly coupled by the internal thread of annular groove 2.1 with the external screw thread of male 3.2 so that dilate spiral shell
Mother 2 forms secondary fixation and is difficult to slide, it is ensured that swell fixture component it is firm.
Described dilates be provided with packing ring between nut 2 and expansion sleeve 3.It is anti-skidding that the expansion sleeve 3 is uniformly provided with some tooth forms
Projection, ensure that expansion sleeve 3 has installation surface to fix more firm.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in the original that reader understands the present invention
Reason, it should be understood that protection scope of the present invention is not limited to such especially statement and embodiment.The ordinary skill of this area
Personnel can be made according to these technical inspirations disclosed by the invention the various other various specific deformations for not departing from essence of the invention and
Combination, these deformations and combination are still within the scope of the present invention.
