Closing, sealing effectiveness is not good and constructs and more bothers again, is badly in need of improving further.
Utility model content
The purpose of this utility model is to overcome the shortcomings of in above-mentioned background technology, provides a kind of cable tube plugging device, should
Device should have good sealing effect and the simple feature of structure.
The technical solution of the utility model is：
A kind of cable tube plugging device, including the flexible seals of annular, is separately positioned on flexible seals both ends of the surface
Annular pressing plate connects as one thus forcing some connections of flexible seals deformation with annular bottom plate and by pressing plate and base plate
Part；Described flexible seals include the inner sleeve and the outer sleeve being located at outer layer positioned at internal layer, described inner sleeve outer circumference surface
On interior annular groove and outer sleeve inner peripheral surface on annular external groove be combined into extension on flexible seals circumferencial direction
Toroidal cavity；It is characterized in that：The inner groovy of described inner sleeve is provided with some circumferentially equally distributed blind holes.
Described blind hole be shaped as rhombus, oval or regular polygon.
Described connector is bolt and the spiral shell for fitted bolt passing through pressing plate, flexible seals and base plate successively
Female.
Described pressing plate is formed by the two arc tablettings being locked by connector with base plate.
It is equipped with parallel to axis on described inner sleeve and outer sleeve and insertion entirely covers the opening of rampart portion.
The beneficial effects of the utility model are：
Inner sleeve of the present utility model is provided with some blind holes, in these blind holes can be lifted when flexible seals deform
The deformation effect of the collar is it is ensured that inner sleeve fits tightly on cable surface so that obtaining between cable tube and inspection shaft effectively
Isolation；Additionally, overall structure of the present utility model is simple, dismounting is very convenient.

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, a kind of cable tube plugging device, if including the flexible seals of annular, pressing plate 1, base plate 2 involvement
Fitting.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 seals
And after base plate, these three parts are connected as one.
Described pressing plate and base plate are circular and pressing plate and are combined by a pair of arc tabletting with base plate, each pressure
Some spliced eyes 51 for installation connecting element are formed with piece, in each tabletting, the quantity of spliced eye is three, three installing holes
It 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 be by two tablettings during combination
Corresponding end spliced eye is superimposed together (can be integrated two tabletting lockings when bolt passes through), is formed therefore on pressing plate
Four spliced eyes that can be for bolt insertion, and four spliced eyes being available for receiving nut are formed on base plate.It is combined into base plate
Spliced eye on two tablettings is 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 end to end interior annular groove 31, the inner peripheral surface of described outer sleeve is provided with and extends in a circumferential direction and be connected to
The annular external groove 41 of circle.It is additionally provided with described inner sleeve and outer sleeve and be easy to be set on cable upper shed 8 and some companies of confession
The bolt slot 52 that fitting interts, described opening extends and insertion inner sleeve or outer on the generatrix direction of inner sleeve or outer sleeve
(during installation, cable may pass through opening and enters in the inner and outer collar of inner sleeve the wall portion of the collar, so that the inner and outer collar of inner sleeve is coated
Outer circumference surface in cable), described inner sleeve two bolt slots corresponding with outer sleeve can form a complete bolt
Hole.Some blind holes 32 are additionally provided with the inner groovy of described inner sleeve, these blind holes are uniformly distributed along the circumferencial direction of inner sleeve,
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 (as Fig. 8
Shown)；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 pressurized, inner sleeve bloats toward internal diameter direction thus being adjacent to cable
Surface, outer sleeve bloats to the outer diameter thus being adjacent to cable inside pipe wall, and in the blind hole on inner sleeve can be remarkably reinforced
Periphery bloat effect, thus improve the sealing effectiveness between flexible seals and cable.
The quantity of described connector is 4 groups, and every group of connector includes bolt 5 and nut 6.Described bolt inserts inserting of pressing plate
After connecing hole and passing through the bolt hole of flexible seals, reconnect the nut being located in base plate spliced eye.Described tabletting is nylon system
Become, described inner sleeve and outer sleeve are made up of rubber.
Installation method of the present utility model is as follows：
First by pressing plate, base plate and flexible seals encapsulation on cable (one end of base plate is near the mouth of pipe of cable tube) make
With connector, these three parts groups are integrally formed, then integrally push this utility model in cable tube, finally tighten connection
The bolt of part forces flexible seals to deform, and the inner peripheral surface of flexible seals is adjacent to outside cable surface flexible seals
Periphery is adjacent in cable inside pipe wall, thus forming sealing inside and outside cable tube, so that cable tube is isolated with inspection shaft.
