Description

Real core hole sealing strip

Technical field

The application belongs to technical field of ship transportation, particularly relates to a kind of real core hole sealing strip.

Background technology

In macromolecular material, rubber is owing to having good mechanical property and high resilience, elastic modelling quantity The least, therefore it is widely used in anti-vibration article.But on the whole, the machinery of elastomeric material is strong Spending on the low side, wearability is poor, and the frictional resistance produced during motion is big, also has certain in terms of media-resistant Limitation.

On existing freighter, many places need to use rubber part to play the effects such as damping, and rubber used by existing freighter Glue part, causes aliquation to bubble owing to salt fog resistance performance is the best or embrittlement is hardened and aging in surface, is formed Potential safety hazard greatly.

Summary of the invention

It is an object of the invention to provide a kind of real core hole sealing strip, to overcome deficiency of the prior art.

For achieving the above object, the present invention provides following technical scheme:

The embodiment of the present application discloses a kind of real core hole sealing strip, including politef body, described Body has the bottom surface of level, is positioned at two sidewalls of vertical direction and from said two sidewall top First lobe with curved surfaces raised up, the top of described first lobe also raises up Having second lobe with curved surfaces, described body extends along direction and is provided with the most disconnected First hole, the second hole and the 3rd hole, described second hole and the 3rd hole be positioned at sustained height, Described first hole is positioned at described second hole and the top in the 3rd hole.

Preferably, in above-mentioned real core hole sealing strip, described second hole and the cross section in the 3rd hole Rounded.

Preferably, in above-mentioned real core hole sealing strip, described first hole includes ellipsoidal cross section The first cavity and protrude out downwards the second tapered cavity from described first cavity bottom, described One cavity connects with described second cavity.

Preferably, in above-mentioned real core hole sealing strip, logical between sidewall and its bottom surface of described body Cross recessed inclined plane to connect.

Preferably, in above-mentioned real core hole sealing strip, the folder between described inclined plane and this body sidewall Angle is 135 °, and the angle between described inclined plane and body bottom surface is 135 °.

Preferably, in above-mentioned real core hole sealing strip, the bottom surface of described body forms zigzag.

Preferably, in above-mentioned real core hole sealing strip, described body is embedded with near one end of bottom surface Magnet.

Compared with prior art, it is an advantage of the current invention that: the present invention uses PTFE stuffing materials, Politef has the most superior chemical stability and low-down coefficient of friction, particularly fills poly- Tetrafluoroethene, owing to adding filler reinforcement material so that it is on the basis of keeping original premium properties, thing Reason mechanical performance is further enhanced so that product hot strength the most significantly exceedes routine >=10Mpa's Index request reaches about 13.4Mpa.

Accompanying drawing explanation

In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to reality Execute the required accompanying drawing used in example or description of the prior art to be briefly described, it should be apparent that below, Accompanying drawing in description is only some embodiments described in the application, for those of ordinary skill in the art From the point of view of, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 show in the specific embodiment of the invention structural representation of real core hole sealing strip.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out Detailed description, it is clear that described embodiment is only a part of embodiment of the present invention rather than complete The embodiment in portion.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation Property work on the premise of the every other embodiment that obtained, broadly fall into the scope of protection of the invention.

Shown in ginseng Fig. 1, real core hole sealing strip includes politef body 1, and body has the end of level Face 11, it is positioned at two sidewalls 12 of vertical direction and from what two sidewall tops raised up, there is arc First lobe 13 on shape surface, the top of the first lobe also raises up and one has curved surfaces Second lobe 14, body extends along direction and is provided with the 15, second hole, the most disconnected first hole 16 and the 3rd hole 17, the second hole and the 3rd hole are positioned at sustained height, and it is empty that the first hole is positioned at second Cave and the top in the 3rd hole.

In this technical scheme, body uses polytetrafluoroethylmaterial material, can be greatly improved its mechanical performance. And coefficient of friction can be effectively improved, effective pre-preventing water leakage.

Further, since body top raises up, therefore when sealing, realize between hatchcover and sealing strip Be linear contact lay so that good airproof performance, antileaking.

Further, the cross section in the second hole and the 3rd hole is rounded.

Further, the first hole includes the first cavity 151 of ellipsoidal cross section and from the first cavity Bottom protrudes out downwards the second tapered cavity 152, the first cavity and the connection of the second cavity.

Further, it is connected by recessed inclined plane 18 between the sidewall of body with its bottom surface.Inclined plane And the angle between this body sidewall is 135 °, the angle between inclined plane and body bottom surface is 135 °.

In this technical scheme, the both sides of main part set to the concave, and can press when compression seal bar with hatchcover Stress under compression is little, prevents the cracking in hole.

Further, the bottom surface of body forms zigzag.

In this technical scheme, by serrated-surface, that can improve between sealing strip and mounting groove is close Feng Xing.

Further, body is embedded with Magnet near one end of bottom surface.

In this technical scheme, by arranging Magnet in sealing strip, sealing strip can directly adsorb in peace Tankage, improves and installs convenience.
