Specific embodiment
In order to describe the technical content, the structural feature, the achieved object and the effect of this invention in detail, below in conjunction with embodiment
And attached drawing is cooperated to be explained in detail.
Fig. 1 and Fig. 2 are please referred to, supporting structure of the present invention is used for the support of shrinkage fingerstall, including cross section is in arc-shaped
Two hard structure bulk-breakings 10, two hard structure bulk-breakings 10 correspond to nested encryptions by side edge and form cylindrical shape.
In the present embodiment, the side edge of two hard structure bulk-breakings 10 is respectively equipped with groove 11, shape between adjacent grooves 11
At double wedge 12, the groove 11 of the side edge of one hard structure bulk-breaking 10, double wedge 12 and another hard structure bulk-breaking double wedge 12,
Groove 11 respectively corresponds nested encryptions.
Preferably, two hard structure bulk-breakings, 10 size of supporting structure is identical, and certainly, two hard structure bulk-breakings 10 can also
With small one and large one, if two-by-two hard structure bulk-breaking 10 can nested encryptions form cylindrical shape.
Preferably, the supporting structure is rigid plastics part.
Preferably, the outside diameter of cylinder of described two hard structure bulk-breakings, 10 one end for forming supporting structure is greater than the other end
Outside diameter of cylinder.When being applied to shrinkage fingerstall, two hard structure bulk-breakings 10 are assembled into the lesser one end of outside diameter of cylinder from it and support
Into the big opening end of shrinkage fingerstall.
Fig. 3, Fig. 4 and Fig. 5 are please referred to, when supporting structure of the present invention is applied to the installation of shrinkage fingerstall, shrinkage fingerstall 20
One end is big opening end 21, and the other end has several osculum ends 22, and the application method of supporting structure is as follows: firstly, referring to shrinkage
20 expansion of set and the big opening end 21 that shrinkage fingerstall 20 is supported with supporting structure, with the osculum end of support bar support shrinkage fingerstall 20
22, it after shrinkage fingerstall 20 is placed into 50 designated position of cable, first extracts osculum end support bar out, chooses the big of shrinkage fingerstall 20
Any hard structure bulk-breaking 10 at mouth end 21, radial pinching hard structure bulk-breaking 10 inside are slightly distorted it, use simultaneously
External force releases hard structure bulk-breaking 10 and takes out, similarly then release other one side hard structure bulk-breaking 10 and take out.
Preferably, the big opening end 21 of shrinkage fingerstall 20 is turned down from inside to outside in advance before the expansion of shrinkage fingerstall 20 certain
Distance, such as turned down at P line.
Preferably, when being turned down before the expansion of shrinkage fingerstall 20, on two 20 contact surfaces of shrinkage fingerstall equably
Smear talcum powder.
As further improvement of this embodiment, formed the outside diameter of cylinder of two hard structure bulk-breakings 10 of supporting structure compared with
Big one end is formed with boss 13, which is equipped with engaging hole 131, and engaging hole 131 can be threaded hole.Choose shrinkage
Any one side of something of 21 supporting structure of big opening end of fingerstall 20, radial wherein a hard structure bulk-breaking 10 makes it slightly to pinching inside
Deformation, while cooperating engaging hole to release hard structure bulk-breaking 10 using extension bar 40 and taking out, it similarly then releases in addition on one side
Hard structure bulk-breaking 10 simultaneously takes out.
As further improvement of this embodiment, shrinkage fingerstall is put when expanding support in supporting structure internal cavities
A support bar equal with cavity inside diameter is set, causes to prop up by the fabricated structure of enclasping force and structural member when preventing support
The dislocation of support structure part and unstable, the removal before shrinkage fingerstall is installed.
In conclusion supporting structure of the present invention includes the two hard structure bulk-breakings 10 that cross section is in arc-shaped, two hard
Structure bulk-breaking 10 corresponds to nested encryptions by side edge and forms cylindrical shape, is being applied to shrinkage fingerstall 20 and from shrinkage fingerstall 20
When big opening end 21 takes out, by radial direction, wherein it is slightly distorted in a hard structure bulk-breaking 10 to pinching inside, while using external force
It releases hard structure bulk-breaking 20 and takes out, similarly then release other one side hard structure bulk-breaking 10 and take out, needed with tradition
It is enough can operating space extraction helical plastic support bar compare, need lesser taking-up space, can adapt to that cable is limited can
The environment of the tight working spaces of operating space or cable periphery.
The invention is not limited to above-mentioned specific embodiment, those skilled in the art can also make a variety of accordingly
Variation, but any be equal or similar variation should all be covered within the scope of the claims with of the invention.
