Specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but this utility model be not limited to
Lower embodiment.
As shown in figure 1, cable tube plugging device, including the flexible seals of annular, pressing plate 1, base plate 2, some connectors,
Air valve 7.Described pressing plate, base plate are separately positioned on the both ends of the surface of flexible seals, and connector sequentially passes through pressing plate, flexible sealing
After part and base plate, these three parts are connected as one.
Described pressing plate and base plate are circular, and pressing plate combined by a pair of arc tabletting with base plate；Each
Some spliced eyes 51 for installation connecting element are formed with tabletting, in each tabletting, the quantity of spliced eye is three, three installations
Hole is located at middle part and the two ends of tabletting respectively.Each pair tabletting passes through combination and forms pressing plate or base plate, need to press two during combination
The corresponding end spliced eye of piece is superimposed together (can be integrated two tabletting lockings when bolt passes through), therefore shape on pressing plate
Become four spliced eyes that can be for bolt insertion, and on base plate, form four to be available for accommodating the spliced eye of nut.It is combined into base plate
Two tablettings on spliced eye be hex hole.
Described flexible seals are circular, including inner sleeve 3 and outer sleeve 4；Described inner sleeve coaxial cloth with outer sleeve
Put and overcoat seal ring is set on the outside of inner sleeve.The outer circumference surface of described inner sleeve is provided with and extends simultaneously in a circumferential direction
And the interior annular groove 31 of the lopping that is connected, the inner peripheral surface of described outer sleeve is provided with and extends in a circumferential direction and head and the tail phase
The annular external groove 41 connecing.It is additionally provided with the opening 8 being easy to be set on cable and some confessions on described inner sleeve and outer sleeve
Connector intert bolt slot 52, described opening extend on the generatrix direction of inner sleeve or outer sleeve and insertion inner sleeve or
(during installation, cable may pass through opening and enters in the inner and outer collar of inner sleeve the wall portion of outer sleeve, makes inner sleeve inner and outer collar bag
Overlay on the outer circumference surface of cable), described inner sleeve two bolt slots corresponding with outer sleeve can form a complete spiral shell
Keyhole.Some blind holes 32 are additionally provided with the inner groovy of described inner sleeve, these blind holes are uniformly divided along the circumferencial direction of inner sleeve
Cloth, the shape of blind hole can be rhombus, oval or regular polygon (as shown in Fig. 5, Fig. 6, Fig. 7), may also be other shapes (such as
Shown in Fig. 8)；The length direction of each blind hole should be parallel to the bus of inner sleeve.
In described flexible seals, the inner groovy of inner sleeve is combined with the external groove of outer sleeve and is formed at flexible seals circle
The toroidal cavity extending in circumferential direction；When flexible seals are when pressurized, inner sleeve bloats toward internal diameter direction thus being adjacent to electricity
Cable surface, outer sleeve bloats to the outer diameter thus being adjacent to cable inside pipe wall, and the blind hole on inner sleeve can be remarkably reinforced
Inner peripheral surface bloat effect, thus improve the sealing effectiveness between flexible seals and cable.
The quantity of described connector is four groups, and every group of connector includes bolt 5 and nut 6.Described bolt inserts pressing plate
Spliced eye after passing through the bolt hole of flexible seals, reconnects the nut being located in base plate spliced eye.Described tabletting is nylon
Make, described inner sleeve and outer sleeve are made up of rubber.
Described air valve is arranged in pressing plate, flexible seals and base plate, and the axis direction of air valve is parallel to bolt
Axis direction.Interior valve port 71 is formed with the tabletting of described base plate, the tabletting of pressing plate is formed with outer valve port 73, flexible seals
Be formed with spiracular furrow 72 on middle inner sleeve and outer sleeve, inner sleeve two spiracular furrows corresponding with outer sleeve can form one complete
Whole valve port.The inlet end (left end of in figure 3) of described air valve is arranged in the interior valve port of base plate, the giving vent to anger of air valve
End is stretched in the outer valve port of pressing plate after passing through the valve port of flexible seals, the inlet end of air valve is with cable tube cavity even
Logical, the outlet side of air valve and ft connection.Described air valve can be with the inner and outer air pressure of balanced cable pipe, it is to avoid this utility model
Lead to seal failure because cable tube internal pressure increases to be pushed out after cable tube.
