The invention discloses a hatch cover sealing strip. The hatch cover sealing strip comprises a polytetrafluoroethylene body, wherein the body comprises a first body which has a first width, and a second body which is formed on the first body and has a second width, and the second width is greater than the first width; three holes are formed in parallel in the middle of the body in an extension direction of the body, and the section of each of the holes is rectangular; and an arc surface is formed on the edge of the bottom end of the first body, and an arc surface is formed on the edge of the top end of the second body. According to the hatch cover sealing strip disclosed by the invention, polytetrafluoroethylene sealing materials are adopted, polytetrafluoroethylene, especially filled polytetrafluoroethylene has extremely predominant chemical stability and quite low friction coefficients, and particularly stuffing reinforcing materials are added, so that on the basis of maintaining original excellent properties, physical and mechanical properties are further improved.

Description

Hatch sealing strip

Technical field

The application belongs to technical field of ship transportation, particularly relates to a kind of Hatch 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 Hatch 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 Hatch sealing strip, including politef body, described body Including there is the first noumenon of the first width and being formed at above described the first noumenon and there is the second width Second body of degree, described second width is more than described first width, and the middle part of described body extends along Three holes it are set side by side with on direction, the rectangular in cross-section in described hole, described the first noumenon bottom Edge is formed with arcwall face, and the tip edge of described second body is formed with arcwall face.

Preferably, in above-mentioned Hatch sealing strip, the sidewall of described the first noumenon and described second body Sidewall between connected by guiding face.

Preferably, in above-mentioned Hatch sealing strip, the sidewall of described guiding face and described the first noumenon it Between in 135 ° of angles.

Preferably, in above-mentioned Hatch sealing strip, the outside of described politef body is also wrapped on Rubber epidermis.

Preferably, in above-mentioned Hatch sealing strip, the upper surface of described body and/or lower surface are sawtooth Shape.

Preferably, in above-mentioned Hatch sealing strip, described body is near its upper surface one end and/or leans on Its lower surface one end nearly is embedded with 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 the structural representation of Hatch sealing strip in the specific embodiment of the invention.

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, Hatch sealing strip includes politef body 1, and body includes having the first width The first noumenon 11 and be formed at above the first noumenon and there is the second body 12 of the second width, Two width are more than the first width, and the middle part of body extends along and is set side by side with three holes 13 on direction, The rectangular in cross-section in hole, the edge of the first noumenon bottom is formed with arcwall face 111, the top of the second body Edge is formed with arcwall face 121.

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.

By being positioned at the hole in the middle of body, the sealing strip elastic space at vertical direction can be improved.

Further, connected by guiding face 14 between sidewall and the sidewall of the second body of the first noumenon. In 135 ° of angles between guiding face and the sidewall of the first noumenon.

Further, the outside of politef body is also wrapped on rubber epidermis.

Further, the upper surface of body and/or lower surface indentation.

In this technical scheme, designed by hackly surface, can improve between sealing strip and draw-in groove, And the sealing between sealing strip and hatchcover, it is to avoid leak.

Further, body is embedded with Magnet near its upper surface one end and/or its lower surface one end close.

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

It should be noted that in this article, the relational terms of such as first and second or the like is used merely to One entity or operation are separated with another entity or operating space, and not necessarily requires or imply Relation or the order of any this reality is there is between these entities or operation.And, term " includes ", " comprise " or its any other variant is intended to comprising of nonexcludability, so that include that one is The process of row key element, method, article or equipment not only include those key elements, but also include the brightest Other key elements really listed, or also include intrinsic for this process, method, article or equipment Key element.In the case of there is no more restriction, statement " including ... " key element limited, It is not precluded from there is also in including the process of described key element, method, article or equipment other identical Key element.

The above is only the detailed description of the invention of the application, it is noted that general for the art For logical technical staff, on the premise of without departing from the application principle, it is also possible to make some improvement and profit Decorations, these improvements and modifications also should be regarded as the protection domain of the application.
