CN106321823A - Solid-core hole straight bar - Google Patents

Abstract

The invention discloses a solid-core hole straight bar. The solid-core hole straight bar comprises a teflon body. The body comprises a first body with the forward trapezoid section and a second body which stretches to the upper side of the first body in a convex mode. The second body is provided with a horizontal top face and side faces which protrude towards the left side and the right side and are provided with arc-shaped surfaces. A vacant cavity with the elliptic section is formed in the middle of the second body. The solid-core hole 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 straight bar in real core hole

Technical field

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

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 the straight bar in a kind of real core hole, 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 the straight bar in a kind of real core hole, including politef body, described Body includes that cross section is the first noumenon of trapezoid and convexedly stretches in second above described the first noumenon Body, described second body have level end face and the most to the left and right both sides protruding there is arc table The side in face, the middle part of described second body offers the hole of ellipsoidal cross section.

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

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

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

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

Preferably, in the above-mentioned straight bar in real core hole, the outside cladding of described politef body There is rubber epidermis.

Preferably, in the above-mentioned straight bar in real core hole, described rubber epidermis and described politef Glue-line is passed through bonding between body.

Preferably, in the above-mentioned straight bar in real core hole, the width of described politef body and height Ratio is 60:65.

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 straight bar in real core hole.

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 straight bar in real core hole include politef body 1, body 1 include cross section in The first noumenon 11 of trapezoid and convexedly stretch in the second body 12 above the first noumenon 11, second Body 12 has the end face 121 of level and both sides are protruding the most to the left and right the side with curved surfaces 122, the middle part of the second body offers the hole 123 of ellipsoidal cross section.

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

The elastic space of sealing strip in the vertical direction can be improved by hole in the middle part of the second body.

The surface by arc, the both sides of the second body, can reduce the compressive stress in compression process, improves The service life of sealing strip.

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 outside of politef body is coated with rubber epidermis.

Further, bonding by glue-line between rubber epidermis with politef body.

Further, the width of described politef body is 60:65 with height ratio.
