Abstract
The present invention relates to closure in a kind of cable channel.In the cable that purpose is to provide, closure should have good airproof performance, easy for installation, the feature of simple in construction.Technical scheme is: closure in a kind of cable channel, including annular flexible seals, be separately positioned on the pressure ring at flexible seals two ends, two pressure rings and flexible seals connected as one and can clamp pressure ring with the some connectors forcing flexible seals to deform；It is characterized in that: on described flexible seals, be shaped with the toroidal cavity extended in a circumferential direction.
Description
Technical field
The present invention relates to field of cables, closure in specifically a kind of cable channel.
Background technology
Closure is a kind of sealing device being arranged in cable channel in cable channel, has simple in construction, easy for installation
Feature.But closure mostly is rubber structure in existing cable, exists and the cable outer wall untight defect of laminating, have impact on
Sealing effect and reduce service life of cable, is further improved.
Summary of the invention
It is an object of the invention to overcome the deficiency in above-mentioned background technology, it is provided that closure in a kind of cable, envelope in this cable
Stifled should have good airproof performance, easy for installation, the feature of simple in construction.
The technical scheme is that
Closure in a kind of cable channel, including annular flexible seals, be separately positioned on the pressure at flexible seals two ends
Ring, two pressure rings connect as one with flexible seals and can clamp pressure ring some it is connected with force that flexible seals deforms
Part；It is characterized in that: on described flexible seals, be shaped with the toroidal cavity extended in a circumferential direction.
Described flexible seals includes inner seal ring and is set in the outer seal ring outside inner seal ring；Described interior sealing
The outer circumference surface of ring is shaped with the interior annular groove extended in a circumferential direction, and the inner peripheral surface of outer seal ring is shaped with at circumferencial direction
The annular external groove of upper extension, inner groovy mutually fastens the described cavity of formation with external groove.
Opening all it is shaped with on described inner seal ring and outer seal ring.
The two ends of described outer seal ring are shaped with the flange wrapping inner seal ring end face.
Described each pressure ring is a pair arc tabletting mutually locked by connector.
Described connector is to pass through two pressure rings and the bolt of flexible seals and the nut for fitted bolt.
The invention has the beneficial effects as follows:
Being provided with cavity in the flexible seals of the present invention, when flexible seals pressurized, two sidewalls of cavity will be outside
Bloating and be tightly fitted on inner-walls of duct and cable outer wall, especially inner seal ring can significantly expand toward conduit axis direction
(expansion distance increase than existing product 2-3 times), thus reliably card nips cable and realizes effectively blocking, it is ensured that good
Sealing effectiveness；Meanwhile, the present invention's is relatively simple for structure, and installation is convenient to.

Detailed description of the invention
Below in conjunction with Figure of description, the invention will be further described, but the invention is not limited in following example.
Closure in cable channel as shown in Figure 1, including flexible seals, two pressure rings 1 and some connections of annular
Part 2.Said two pressure ring is separately positioned on flexible seals two ends, and connector passes through two pressure rings and will press after flexible seals
Ring connects as one with flexible seals.Described connector is bolts and nuts.
Described each pressure ring includes a pair arc tabletting, and each tabletting is all shaped with some installing holes interted for connector
11；As shown in Figure 6, each tabletting arranging three installing holes, these three installing hole lays respectively at middle part and the both sides of tabletting
End；The end of two tablettings of juxtaposition also makes two installing holes of end position coincide with the upper and lower, then is inserted by connector
Installing hole locks the two tabletting, so that it may tabletting is assembled into pressure ring.
Described flexible seals includes inner seal ring 3 and outer seal ring 4；Described inner seal ring 3 coaxially sets with outer seal ring
Put and outer seal ring is set in the outside of inner seal ring；The outer circumference surface of described inner seal ring is shaped with and extends in a circumferential direction
Interior annular groove；The inner peripheral surface of described outer seal ring is shaped with the annular external groove extended in a circumferential direction, and the closeest
The two ends of seal ring are shaped with the flange 41 stretched toward center；Also it is shaped with on described inner seal ring and outer seal ring and is easy to be set on cable
Upper shed C and some through holes interted for connector, described opening prolongs on the generatrix direction of inner seal ring or outer seal ring
Stretch.
When inner seal ring is set-located with outer seal ring, the flange of outer seal ring wraps two end faces of inner seal ring
Inner seal ring is embedded in the inner peripheral surface of outer seal ring, and inner groovy mutually fastens formation one in flexibility with external groove
On sealing member circumferencial direction extend toroidal cavity 5, this cavity can make flexible seals when pressurized its inside and outside circle side face all to
Bloat outward.
Described tabletting is that nylon is made, and described inner seal ring and outer seal ring are that rubber is made.
The installation method of the present invention is as follows:
First by flexible seals and pressing plate encapsulation on cable, then by connector by flexible seals with pressing plate even
Connect fixing, and flexible seals and pressing plate entirety are pushed in pipeline, more gradually tighten the nut of connector so that pressure ring is continuous
Ground clamping flexible seals, flexible seals deforms upon under pressure, and the inner peripheral surface of flexible seals is adjacent at electricity
Cable outer wall, the outer circumference surface of flexible seals is adjacent at inner-walls of duct, thus is formed inside and outside pipeline and seal.
