In order to achieve the above objectives, a kind of the technical solution adopted by the present invention are as follows: inner lining body for shrinkage part, comprising: tool
There is the elastic piece of thickness, the two sides of the elastic piece is respectively the inner surface and the outer surface, which is characterized in that is set on the inner surface
Several V-grooves are equipped with, described elastic piece a side end face is equipped with recessed arc groove, and another lateral end panel of elastic piece is set
Have the arc of protrusion convex stupefied, the arc it is convex it is stupefied in set through-hole, filling silk is provided in the through-hole；
Convex stupefied, the described through-hole of the arc, the arc groove and the axis of the V-groove are mutually parallel.
In a preferred embodiment of the present invention, the inner surface and the outer surface close to arc groove is provided with hard baffle.
In a preferred embodiment of the present invention, it is arcwall face that the convex stupefied elastic piece end face of the arc, which is arranged,.
In a preferred embodiment of the present invention, the convex stupefied cross-sectional shape of arc is the circular arc that radian is greater than 240 °
Shape.
In a preferred embodiment of the present invention, the curved slot arrangement and the convex stupefied structure of the arc are coincide, and the arc
Shape is convex stupefied to be capable of the snapping onto the arc groove of size interference.
In a preferred embodiment of the present invention, several V-grooves are equidistantly arranged on the internal surface.
In a preferred embodiment of the present invention, elastic piece described in bending make the arc it is convex it is stupefied snap onto the arc groove,
It is circular cylinder that elastic piece, which forms cross section, at this time.
In a preferred embodiment of the present invention, at least three filling silks are provided in the through-hole.
In a preferred embodiment of the present invention, the filling silk is wire.
The invention solves the defect existing in the background technology, the present invention have it is following the utility model has the advantages that
(1) by the convex stupefied mating structure with arc groove of setting arc, guarantee that elastic piece can form tubular by bending
Or column construction, such silicon rubber shrinkage part can be softened in the column construction periphery that elastic piece is formed.
(2) several V-grooves are set, and in this way in bending process, the meeting nature inner surface of elastic piece forms curved bend
Song, just cross section easy to form is circular structure to elastic piece, and V-groove has curved guiding performance.
(3) through-hole through arc it is convex stupefied, by arc it is convex it is stupefied snap onto arc groove or taken apart from arc groove when, through-hole
It is inside first not filled with wire, is easy deformation in this way and is easy that the arc squeezed is convex stupefied can easily to enter or be detached from arc groove；To
Arc it is convex it is stupefied snap onto arc groove after, elastic piece is formed when needing stable cylindrical supports, and the convex stupefied comparison of arc is stiffening, no
It is easy to be detached from out of arc groove, when needing to remove supporting element, as long as gradually extracting the wire in through-hole out, through-hole loses metal
After silk support is deflated, the convex stupefied entirety of arc also loses support, and structure becomes soft, and elastic piece can be easily from support silicon rubber at this time
It is removed in glue shrinkage part.
(4) hard baffle can guarantee that arc groove peripheral structure intensity is relatively high, and arc is convex stupefied can be stuck in by stable
In arc groove.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples；
Fig. 1 is the flowage structure figure of the bending of the preferred embodiment of the present invention；
In figure: 1, elastic piece；2, inner surface；3, outer surface；4, arc groove；5, arc is convex stupefied；6, V-groove；7, through-hole；8,
Wire；9, hard baffle.
Specific embodiment
Presently in connection with drawings and examples, the present invention is described in further detail, these attached drawings are simplified signal
Figure, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
As shown in Figure 1, a kind of inner lining body for shrinkage part, comprising: the elastic piece with thickness, the two of the elastic piece
Face is respectively the inner surface and the outer surface, several V-grooves are provided on inner surface, and described elastic piece a side end face is equipped with recessed
Arc groove, the arc that another lateral end panel of elastic piece is equipped with protrusion is convex stupefied, the arc it is convex it is stupefied in set through-hole, it is described logical
Three one metal wires are provided in hole.
Through-hole is convex stupefied through arc, by arc it is convex it is stupefied snap onto arc groove or taken apart from arc groove when, in through-hole
It is first not filled with wire, is easy deformation in this way and is easy that the arc squeezed is convex stupefied can easily to enter or be detached from arc groove；To arc
Shape it is convex it is stupefied snap onto arc groove after, elastic piece is formed when needing stable cylindrical supports, and the convex stupefied comparison of arc is stiffening, does not allow
It is easily detached from out of arc groove, when needing to remove supporting element, as long as gradually extracting the wire in through-hole out, through-hole loses wire
Support it is deflated after, the convex stupefied entirety of arc also loses support, and structure becomes soft, and elastic piece can be cold from silicon rubber easily at this time
It is removed in contracting part.
Convex stupefied, the described through-hole of arc, the arc groove and the axis of the V-groove are mutually parallel.By the way that arc is arranged
Convex stupefied and arc groove mating structure guarantees that elastic piece can form tubular or column construction by bending, and such silicon rubber is cold
Contracting part can be softened in the column construction periphery that elastic piece is formed.
The inner surface and the outer surface close to arc groove is provided with hard baffle.Hard baffle can guarantee arc groove periphery
Structural strength is relatively high, and arc is convex stupefied can be stuck in arc groove by stable.
It is arcwall face that the convex stupefied elastic piece end face of the arc, which is arranged,.
The convex stupefied cross-sectional shape of arc is that radian is arc-shaped greater than 240 °, curved slot arrangement and the convex stupefied knot of the arc
Structure coincide, and the arc is convex stupefied is capable of the snapping onto the arc groove of size interference.
Several V-grooves are equidistantly arranged on the internal surface.Several V-grooves are set, in this way in bending
Cheng Zhong, the meeting nature inner surface of elastic piece form arc-shaped bend, and just cross section easy to form is circular structure, V to elastic piece
Type groove has curved guiding performance.
Elastic piece described in bending make the arc it is convex it is stupefied snap onto the arc groove, at this time elastic piece formed cross section be circle
The cylinder of shape.
Bending elastic piece make arc it is convex it is stupefied snap onto arc groove, at this time elastic piece formed cross section be rectangle cylinder.
Filler or inflated airbag can be filled in the inner cavity of cylinder, in this way in external force, cylinder will not be deflated.
Based on the above description of the preferred embodiments of the present invention, through the above description, related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
It is not limited to the contents of the specification, it is necessary to determine the technical scope according to the scope of the claims.
