Description

The detachable cable rubber seal of a kind of multilayer

Technical field

The utility model relates to a kind of cable sealing device, relates in particular to the detachable cable rubber seal of a kind of multilayer.

Background technology

The main in the market cable sealing device of using is simple in structure, each sealing device only limits to the cable of same external diameter, flexibility is relatively poor, and, contain harmful substances such as halogen mostly in the used material of traditional cable sealing device, simultaneously, the anti-knock properties of traditional cable sealing device, anti-aging and radiation resistance is all poor, also can ftracture, thereby reduce the sealing of cable crossing position, the situation of leaking, leaking gas consequently occur along with variation of temperature.In addition, traditional cable sealing device can not be reused, thereby has increased entreprise cost.

The utility model content

The purpose of this utility model provides the detachable cable rubber seal of a kind of multilayer, and the existing cable sealing device is poorly sealed to overcome, very flexible, easy season cracking and can't reusable defective.

The purpose of this utility model is to be achieved through the following technical solutions:

The detachable cable rubber seal of a kind of multilayer comprises high-quality mild steel or acid-resistant stainless steel framework, hold down gag and module, and described module is installed in the framework, and described hold down gag compresses described module; It is that raw material is made that described framework adopts high-quality mild steel or acid-resistant stainless steel, and resistance to pressure is stronger, and framework is cuboid, is provided with a square through hole in the framework; The following rubber half block that adds peelable sandwich layer that described module comprises the rubber half block that can add peelable sandwich layer and is connected in the rubber half block below that can add peelable sandwich layer, can add the rubber half block of peelable sandwich layer on described, can add down all has multilayer to add to peel off sandwich layer on the rubber half block of peelable sandwich layer, two surfaces that sandwich layer is peeled off in every layer of interpolation evenly are provided with groove and raised item, the width of described groove and raised item is identical, and the degree of depth of groove is identical with the height of raised item, adjacent two layers adds groove and the raised item of peeling off sandwich layer and interconnects, on can add the rubber half block of peelable sandwich layer, can add down in the rubber half block of peelable sandwich layer a semi-circular recesses is arranged all so that on can add the rubber half block of peelable sandwich layer, when being connected, the rubber half block that can add peelable sandwich layer down just forms a manhole in inside, but the usefulness that this through hole current supply cable passes through, simultaneously, in order to satisfy the demand of various outer diameter cable, the described sandwich layer of peeling off can add or peel off one or more layers interpolation and peel off sandwich layer to reach the external diameter of complete Adapter Cable for to form through the high pressure technique pressing when needing; Described hold down gag is positioned at the top of module, and hold down gag is furnished with two bolts, can compression module by this bolt; Described hold down gag and module are raw material with halogen rubber all.

The beneficial effect of the detachable cable rubber seal of multilayer described in the utility model is: versatile and flexible, need not learn the concrete specification of cable in advance, take multiple scheme combination also can use the sealing of this product, and individual module can seal cables with different diameters; Reusable, make enterprise save cost; Good sealing effect; Compression resistance, heat-resistingization can be resisted most of chemical corrosions, and anti-aging is good, radioresistance, explosion-proof, vibratility are strong, even out of doors also can be by rodent, and ant and other insects are destroyed.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the detachable cable rubber seal of the described multilayer of a utility model embodiment dismounting schematic diagram;

Fig. 2 is the transverse sectional view of module 3 among Fig. 1;

Fig. 3 is the longitudinal sectional view of module 3 among Fig. 1.

Among the figure:

1, framework; 2, hold down gag; 3, module; 4, bolt; 5, can add the rubber half block of peelable sandwich layer on; 6, can add the rubber half block of peelable sandwich layer down; 7, sandwich layer is peeled off in interpolation; 8, groove; 9, raised item.

Embodiment

As Figure 1-3, the detachable cable rubber seal of the described multilayer of the utility model embodiment, constitute by framework 1 and the hold down gag 2, the module 3 that are embedded in the framework 1, it is raw material that described framework 1 adopts high-quality mild steel or acid-resistant stainless steel, resistance to pressure is stronger, framework 1 is cuboid, is provided with a square through hole in the framework 1; The following rubber half block 6 that adds peelable sandwich layer that described module 3 comprises the rubber half block 5 that can add peelable sandwich layer and is connected in rubber half block 5 belows that can add peelable sandwich layer, can add the rubber half block 5 of peelable sandwich layer on described, can add down all has multilayer to add to peel off sandwich layer 7 on the rubber half block 6 of peelable sandwich layer, two surfaces that sandwich layer 7 is peeled off in every layer of interpolation evenly are provided with groove 8 and raised item 9, described groove 8 is identical with the width of raised item 9, and the degree of depth of groove 8 is identical with the height of raised item 9, adjacent two layers adds groove 8 and the raised item 9 of peeling off sandwich layer 7 and interconnects, on can add the rubber half block 5 of peelable sandwich layer, can add down in the rubber half block 6 of peelable sandwich layer a semi-circular recesses is arranged all so that on can add the rubber half block 5 of peelable sandwich layer, when being connected, the rubber half block 6 that can add peelable sandwich layer down just forms a manhole in inside, but the usefulness that this through hole current supply cable passes through, simultaneously, in order to satisfy the demand of various outer diameter cable, described interpolation is peeled off sandwich layer 7 for to form through the high pressure technique pressing, can add or peel off one or more layers interpolation when needing and peel off sandwich layer 7 to reach the external diameter of complete Adapter Cable; Described hold down gag 2 is positioned at the top of module 3, and hold down gag 2 is furnished with two bolts 4, can compression module 3 by this bolt 4; Described hold down gag 2 is a raw material with halogen rubber all with module 3.

During use, earlier framework 1 is connected on body of wall or other barrier structures by welding, cast or with bolt, make it form unified integral body, the framework 1 of again module 3 being packed into, and module 3 is compressed with hold down gag 2, because hold down gag 2 all is raw material with the elastic caoutchouc with module 3, has fabulous sealing effectiveness after therefore exerting pressure by 2 pairs of modules 3 of hold down gag; Simultaneously, if the external diameter that the through-hole aperture of module 3 can not appropriate cable, if with on can add the rubber half block 5 of peelable sandwich layer, the interpolation that can add the rubber half block 6 of peelable sandwich layer down peels off sandwich layer 7 and adds or remove one or more layers so that described through-hole aperture reaches the external diameter of complete Adapter Cable; And after hold down gag 2 unloaded, module 3 can be recovered its original shape automatically in order to reusing.

The design of groove 8 and raised item 9 connected modes makes adjacent two layers add to peel off being connected of sandwich layer 7 tightr, is difficult for sliding, and has improved the anti-knock properties and the anti-shake performance of module whole, has also improved performances such as module waterproof, gas-tight, fire prevention simultaneously.
