Abstract

The application discloses real core hole sealing strip of cabin cover, including the polytetrafluoroethylene body, the top of body is stretched to the epirelief and is had first bellying, and this first bellying has curved surface, the left and right sides of body is stretched to the evagination respectively and is had second bellying and third bellying, second bellying and third bellying symmetry set up, just second bellying and third bellying have curved surface, the body is equipped with a cross -section along its extending direction and is the circular shape hole, the body still has a horizontally bottom surface. The utility model discloses a teflon seal material, polytetrafluoroethylene have extremely superior chemical stability and very low coefficient of friction, especially pack polytetrafluoroethylene, owing to add the filler reinforcement material, make it on keeping the basis of original premium properties, and physical -mechanical properties obtains further improvement.

Description

Hatchcover real core hole weather strip

Technical field

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

Background technology

In macromolecular material, rubber is owing to having good mechanical property and high resilience, and modulus of elasticity is very little, is therefore widely used in anti-vibration article.But on the whole, the mechanical strength of elastomeric material is on the low side, and abrasion resistance is poor, the frictional resistance produced during motion is large, in media-resistant, also have certain limitation.

On existing freighter, many places need to use rubber part to play the effects such as damping, and existing rubber part for cargo ship, cause aliquation to bubble or harden embrittlement and aging in surface because salt fog resistance performance is not good, form great potential safety hazard.

Utility model content

The purpose of this utility model is to provide a kind of hatchcover real core hole weather strip, to overcome deficiency of the prior art.

For achieving the above object, the utility model provides following technical scheme:

The embodiment of the present application discloses a kind of hatchcover real core hole weather strip, comprise polytetrafluoroethylene (PTFE) body, the top of described body has upwards protruded out the first lug boss, this the first lug boss has the surface of arc, the left and right sides of described body is respectively to having protruded out the second lug boss and the 3rd lug boss outward, described second lug boss and the 3rd lug boss are symmetrical arranged, and described second lug boss and the 3rd lug boss have the surface of arc, described body is provided with rounded hole, a cross section along its bearing of trend, and described body also has the bottom surface of a level.

Preferably, in the weather strip of above-mentioned hatchcover real core hole, the outside of described polytetrafluoroethylene (PTFE) body is also coated with rubber epidermis.

Preferably, in the weather strip of above-mentioned hatchcover real core hole, the bottom surface indentation of described body.

Preferably, in the weather strip of above-mentioned hatchcover real core hole, described body is embedded with magnet near one end of its bottom surface.

Compared with prior art, the utility model has the advantage of: the utility model adopts PTFE stuffing materials, polytetrafluoroethylene (PTFE) has extremely superior chemical stability and low-down friction factor, particularly filled polytetrafluoroethylene, owing to adding filler reinforcement material, make it on the basis keeping original premium properties, physical and mechanical properties is further enhanced, and the index request making product hot strength significantly exceed routine >=10Mpa reaches about 13.4Mpa.

Accompanying drawing explanation

In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Figure 1 shows that the structural representation of hatchcover real core hole weather strip in the utility model specific embodiment.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be described in detail the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.

Shown in ginseng Fig. 1, hatchcover real core hole weather strip comprises polytetrafluoroethylene (PTFE) body 1, the top of body has upwards protruded out the first lug boss 11, this first lug boss has the surface 111 of arc, the left and right sides of body is respectively to having protruded out the second lug boss 12 and the 3rd lug boss 13 outward, second lug boss and the 3rd lug boss are symmetrical arranged, and the second lug boss and the 3rd lug boss have the surface of arc, body is provided with rounded hole 14, a cross section along its bearing of trend, and body also has the bottom surface 15 of a level.

In this technical scheme, body adopts polytetrafluoroethylmaterial material, can greatly improve its mechanical performance.And effectively can improve friction factor, effectively pre-preventing water leakage.

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

The curved surface, top of weather strip, linearly can contact with being formed between hatchcover, effectively improves sealing effectiveness.

The weather strip left and right sides has curved surfaces, can and the sidewall of draw-in groove between formed and linearly contact, effectively improve sealing effectiveness.

Further, the outside of polytetrafluoroethylene (PTFE) body is also coated with rubber epidermis.

Further, the bottom surface indentation of body.

In this technical scheme, designed by hackly surface, the sealing between weather strip and draw-in groove can be improved, avoid leaking.

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

In this technical scheme, by arranging magnet in weather strip, weather strip directly can be adsorbed on mounting groove, improves and installs convenience.

It should be noted that, in this article, the such as relational terms of first and second grades and so on is only used for an entity or operation to separate with another entity or operating space, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially.And, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising described key element and also there is other identical element.

The above is only the detailed description of the invention of the application; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the application's principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection domain of the application.
