Description

One side foreskin politef is straight bar

Technical field

The application belongs to technical field of ship transportation, particularly relates to a kind of one side foreskin politef and puts down Vertical bar.

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 one side straight bar of foreskin politef, to overcome existing skill Deficiency in art.

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

The embodiment of the present application discloses a kind of one side straight bar of foreskin politef, including politef Body and be coated on the rubber epidermis of described body upper surface, described body includes that cross section is that isosceles are fallen Trapezoidal the first noumenon and to convexedly stretch in square section on described the first noumenon be second of isosceles trapezoid Body, the side of described the first noumenon and the angle of horizontal direction are 75 °, the side of described second body with The angle of horizontal direction is 45 °, and the inside of described the first noumenon extends along direction and is provided with a cross section is circle The hole of shape.

Preferably, in the above-mentioned one side straight bar of foreskin politef, the surface of described rubber epidermis Form zigzag.

Preferably, in the above-mentioned one side straight bar of foreskin politef, described rubber epidermis and poly-four It is additionally provided with Magnet between fluorothene body.

Preferably, in the above-mentioned one side straight bar of foreskin politef, described politef body It is connected by mucilage layer with between described rubber epidermis.

Compared with prior art, it is an advantage of the current invention that:

The present invention uses PTFE stuffing materials, politef to have the most superior chemically stable Property and low-down coefficient of friction, particularly filled polytetrafluoroethylene, due to add filler reinforcement material, Making it on the basis of keeping original premium properties, physical and mechanical properties is further enhanced so that produce Product hot strength the most significantly exceedes the index request of routine >=10Mpa and reaches about 13.4Mpa.

It addition, the straight bar of the politef of the present invention also has chemicals-resistant, oil resistant and resistant to elevated temperatures excellent Point.

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 cross section signal of the straight bar of one side foreskin politef in the specific embodiment of the invention Figure.

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, one side foreskin politef is straight, and bar includes politef body 1 and bag Be overlying on the rubber epidermis 2 of body upper surface, body 1 include cross section be isosceles inverted trapezoidal the first noumenon 11, And convexedly stretch in the second body 12 that square section on the first noumenon is isosceles trapezoid, the side of the first noumenon 111 is 75 ° with the angle of horizontal direction, and the side 121 of the second body with the angle of horizontal direction is 45 °, the inside of the first noumenon extends along direction and is provided with rounded hole, a cross section 13.

In this technical scheme, body uses polytetrafluoroethylmaterial material, can be greatly improved its mechanical performance And frictional behaviour.

It addition, the teflon seal bar of the present invention also has chemicals-resistant, oil resistant and resistant to elevated temperatures excellent Point.

In this technical scheme, the elastic space of compression direction can be improved by hole, improve sealing.

Further, the surface of rubber epidermis forms zigzag.

In this technical scheme, by serrated-surface, teflon seal bar and hatchcover can be improved Between sealing.

Further, it is additionally provided with Magnet between rubber epidermis and politef body.

In this technical scheme, by arranging Magnet in teflon seal bar, politef is close Strip of paper used for sealing can directly adsorb on hatchcover or draw-in groove, improves and installs convenience.

Further, it is connected by mucilage layer between politef body with rubber epidermis.

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 ...
