Description
【Technical field】
The utility model patent is related to cable channel field of sealing technology, and especially a kind of expanding reducing cable channel is blocked up
Plug.
【Background technology】
It is that extrusion pressing type is blocked mostly that cable channel, which is blocked, in existing technology, and traditional extrusion pressing type is blocked to be squeezed by screw completely
Pressure apron expands in itself, and apron bears all extruding forces, but apron has the elastic fatigue phase, so as to slowly follow the string, therefore
When running into hydraulic pressure, the blocking gradually followed the string will come off, and the diameter blocked using this extrusion pressing type expansion pattern is variable
Footpath scope is smaller, the maximum expansible 1mm~5mm of internal orifice of blocking, and is difficult the deviation for the deviation and cable for adapting to internal diameter of the pipeline,
When being expressed to maximum variable footpath because the friction area reduction with tube wall, the ability to bear of hydraulic pressure decline, cause sealing effectiveness
Decline, water is entered in pipeline, do not reach the effect of closure, seam crossing when docking due to producing when two pieces of rubber stopper docking
Gap, sealing effectiveness is declined again, earthworm, mouse, snake and termite is entered pipeline and cable bad in pipeline, this
Kind of mode structure is complex, causes assembling difficult to workmen, improves construction man-hour, and enterprise production cost compared with
It is high.
【The content of the invention】
In order to solve the above technical problems, the utility model proposes a kind of blocking of expanding reducing cable channel, including
Body, described body is provided with seam, and described seam crossing is provided with sealing rod, described body and is additionally provided with leather sheath；Institute
The body stated also includes apron, and described apron is to be provided with angle on inside and outside two aprons, described apron, in two,
The centre of outer apron is provided at both ends with two annular cones, two described annular cones and is provided with screw rod, described screw rod
Two annular cones are connected, two described annular cones are by tie-rod, and two described annular cones pass through screw rod
Two aprons are driven inwardly to expand outwardly after tension.
It is further preferred, described apron, angle and this body by integral forming；The angle of inclination of angle is on the apron
60~150 degree, described annular cone for ABS materials annular cone or SMC materials annular cone or PA materials annular cone or
The materials such as alloying metal.
Further preferred, the outside expansible 10mm~20mm of the apron can be applicable the reducing of more pipelines；Institute
State apron inwardly expansible 10mm~15mm, the cable of applicable more diameter models；Described screw rod is provided with 6~14,
Described sealing rod is fire-type sealing rod, described fire-type sealing rod water-swellable.
The utility model patent, annular cone is installed by the two ends in the middle of two aprons, recycles screw rod by annular
Cone is connected, and drives two annular cones to be moved to relative direction when screw rod steps up, annular cone is borrowed while motion
External force strut apron, make the inside and outside expansion of apron；Meanwhile, when running into inner pipe water pressure, due to the active force of inner pipe water pressure, on the contrary
Promote two annular cones to be moved to relative direction, annular cone and whole blocking is pressed tighter and tighter, the bigger pressure of hydraulic pressure is more
Tightly, and reach two annular cones step up again and again borrow annular cone external force strut apron, make apron inwardly, extend out
；So will not cause to come off, therefore whole blocking, by using fire-type sealing rod in seam crossing, can be made with long-term seal
Waterproof sealing effect improve again；Adapt it in pipeline mounting construction because the internal diameter of the pipeline of each pipeline factory offer is inclined
Difference, interior diameter expansion can make the cable that any model is applicable when installation.
The utility model patent structure is simple, easy for installation to be known a priori by the accurate internal diameter of pipeline for workmen
Products scheme is done with the accurate external diameter of cable, construction man-hour is reduced, strengthens sealing effectiveness, is that enterprise reduces and is produced into
This.

Fig. 1 is the unexpanded pre-structure schematic diagram of the utility model diameter；
Fig. 2 is structural representation after the utility model expanded in diameter；
Fig. 3 is the unexpanded preceding overall structure diagram of the utility model；
Fig. 4 is overall structure diagram after the utility model expansion；
Indicated in figure：1- bodies, 2- aprons, 3- angles, 4- annular cones, 5- screw rods, 6- seams, 7- leather sheaths.
【Embodiment】
It is described the utility model proposes a kind of blocking of expanding reducing cable channel, including body 1 refering to Fig. 1~4
Body be provided with seam 6, be provided with sealing rod, described body 1 at described seam 6 and be additionally provided with leather sheath 7；Described sheet
Body also includes being provided with angle 3 on apron 2, described apron 2, and two rings are provided at both ends with the centre of two inside and outside aprons
Screw rod 5 is provided with shape cone 4, two described annular cones 4, described screw rod 5 connects two annular cones 4, described
Two annular cones 4 tensed by screw rod 5, described two annular cones 4, which pass through after screw rod 5 is tensed, drives two aprons 2
Inwardly expand outwardly.Further preferably the angle of inclination of angle 3 on the apron 2 is 60~150 degree, described annular cone
Body 4 is ABS materials annular cone or the material such as SMC materials annular cone or PA materials annular cone or alloying metal；Wherein, institute
Apron, angle and this body by integral forming stated；The outside expansible 10mm~20mm of the apron 2, can be applicable more pipelines
Reducing；The inside expansible 10mm~15mm of the apron 2, the cable of applicable more diameter models；Described screw rod is set
There are 6~14, described sealing rod is fire-type sealing rod, described fire-type sealing rod water-swellable.
The utility model patent, annular cone 4 is installed by the two ends in the middle of two aprons 2, recycles screw rod by ring
Shape cone 4 is connected, and drives two annular cones 4 to be moved to relative direction when screw rod 5 steps up, and annular is borrowed while motion
The external force of cone 4 struts apron, makes that apron 2 is inside, outer expansion；Meanwhile, when running into inner pipe water pressure, due to the effect of inner pipe water pressure
Power, promotes two annular cones 4 to be moved to relative direction on the contrary, annular cone 4 and whole blocking is pressed tighter and tighter, hydraulic pressure is got over
That presses greatly is tighter, and borrows the external force of annular cone 4 again and strut apron and apron 2 is expanded again to inside and outside；So will not lead
Cause comes off, therefore, by using fire-type sealing rod in the seam crossing of body 1, can make the anti-watertight entirely blocked with long-term seal
Envelope effect is improved again；The internal diameter of the pipeline deviation provided in pipeline mounting construction by each pipeline factory, interior diameter are provided
Expansion can make the cable that any model is applicable when installation.
The utility model patent structure is simple, easy for installation to be known a priori by the accurate internal diameter of pipeline for workmen
Products scheme is done with the accurate external diameter of cable, construction man-hour is reduced, strengthens sealing effectiveness, is that enterprise reduces and is produced into
This.
It, to explanation of the present utility model, is limited of the present utility model that above-described embodiment, which is, any new to this practicality
Scheme after type simple transformation belongs to protection domain of the present utility model.
