CN106321825A - Solid-core straight bar - Google Patents

Abstract

The invention discloses a solid-core straight bar. The solid-core straight bar comprises a teflon body. The body comprises a first body with the rectangular section and a second body which stretches to the upper side of the first body in a convex mode and has a forward isosceles trapezoid section. An included angle formed by the side edges of the second body and the horizontal direction is 45 degrees. The solid-core straight bar is made of a teflon sealing material, teflon has extremely-excellent chemical stability and low friction coefficients, and the straight bar is especially filled with the teflon. Due to the fact that a reinforced material is added and filled, the physical and mechanical properties can be further improved on the basis of keeping original good performance.

Description

The real straight bar of core

Technical field

The application belongs to technical field of ship transportation, particularly relates to a kind of real straight bar of core.

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 straight bar of core, 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 straight bar of core, including politef body, described body Including the first noumenon of rectangular in cross-section and to convexedly stretch in the cross section above described the first noumenon be positive isosceles The second trapezoidal body, the side of described second body and the angle of horizontal direction are 45 °.

Preferably, in the above-mentioned straight bar of real core, the bottom surface indentation of described the first noumenon.

Preferably, in the above-mentioned straight bar of real core, the end face indentation of described second body.

Preferably, in the above-mentioned straight bar of real core, described the first noumenon is embedded near one end of its bottom surface There is Magnet.

Preferably, in the above-mentioned straight bar of real core, described second body is embedded near one end of its end face There is Magnet.

Preferably, in the above-mentioned straight bar of real core, the width of described politef body and height ratio For 50:35.

Preferably, in the above-mentioned straight bar of real core, the middle part of described politef body offers to be cut The hole that face is rounded.

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 the real straight bar of core.

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, the real straight bar of core, including politef body 1, body 1 includes that cross section is square The first noumenon 11 of shape and to convexedly stretch in the cross section above described the first noumenon be the second of positive isosceles trapezoid Body 12, the side of described second body and the angle of horizontal direction are 45 °.

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

Further, the bottom surface indentation of the first noumenon.The end face indentation of the second body.

In this technical scheme, by serrated-surface, can improve sealing strip and hatchcover, sealing strip with Sealing between draw-in groove.

Further, the first noumenon is embedded with Magnet near one end of its bottom surface.Second body pushes up near it The one end in face is embedded with Magnet.

In this technical scheme, by arranging Magnet in sealing strip, sealing strip can directly adsorb in cabin On lid or draw-in groove, improve and convenience is installed.

Further, the width of described politef body is 50:35 with height ratio.

The middle part of described politef body offers the hole that cross section is rounded.

In this technical scheme, sealing strip can be improved perpendicular by hole in the middle part of politef body Nogata elastic space upwards.

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.
