Description

Straight angle joint

Technical field

The application belongs to technical field of ship transportation, particularly relates to a kind of straight angle joint.

Background technology

In High molecular 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 resistance to abrasion is poor, the friction drag 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.

Angle joint at present for the sealing of cargo hold lid forms by single sponge foaming.Although this sponge angle joint good springiness, lightweight, easily aging, easy compressive deformation, service life is short.

Utility model content

The purpose of this utility model is to provide a kind of straight angle joint, 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 straight angle joint, comprise L-shaped polytetrafluoroethylene sponge core and to described sponge core form that three bread cover rubber epidermis, described sponge core have rectangular in cross-section body and protrude out downwards from described body lower end in the convex extension part of isosceles inverted trapezoidal, described rubber epidermis comprise be coated on described body end face the first epidermis, be coated on the second table epidermis of described body side and be coated on the 3rd epidermis of side, described convex extension part.

Preferably, in above-mentioned straight angle joint, the angle between described 3rd epidermis and the second epidermis is 135 °.

Preferably, in above-mentioned straight angle joint, the end face of described first epidermis forms zig-zag.

Preferably, in above-mentioned straight angle joint, between described first epidermis and described sponge core, be provided with magnet.

Preferably, in above-mentioned straight angle joint, be connected by mucilage layer between described sponge core with described epidermis.

Preferably, in above-mentioned straight angle joint, by sulfur foam compound between described epidermis and sponge core.

Compared with prior art, the utility model has the advantage of:

The utility model is by rubber peel on the periphery of sponge core is coated, and under the original elastomeric prerequisite of maintenance sponge core angle joint, resistance to ag(e)ing is good, and compress variation is little, long service life.

The utility model adopts PTFE stuffing materials, polytetrafluoroethylene has extremely superior chemical inertness and low-down friction coefficient, 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 pulling strengrth 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 section drawing of straight angle joint in the utility model specific embodiment;

Figure 2 shows that the birds-eye view of straight angle joint 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 and Fig. 2, straight angle joint comprise L-shaped polytetrafluoroethylene sponge core 1 and to sponge core form that three bread cover rubber epidermis 2, sponge core have rectangular in cross-section body 11 and protrude out downwards from body lower end in the convex extension part 12 of isosceles inverted trapezoidal, rubber epidermis 2 comprise be coated on body end face the first epidermis 21, be coated on the second table epidermis 22 of body side and be coated on the 3rd epidermis 23 of side, convex extension part.

In this technical scheme, sponge core adopts polytetrafluoroethylmaterial material, can greatly improve its mechanical characteristics.

Further, the angle between the 3rd epidermis and the second epidermis is 135 °.

Further, the end face of the first epidermis forms zig-zag.

In this technical scheme, by serrated-surface, the leak tightness between sealing band and hatchcover can be improved.

Further, magnet is provided with between the first epidermis and sponge core.

In this technical scheme, by arranging magnet in sealing band, sealing band can directly be adsorbed on hatchcover, improves and installs convenience.

Further, be connected by mucilage layer between sponge core with epidermis.

Further, sulfur foam compound is passed through between epidermis and sponge core.

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 operational zone, 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 ...
