Description

Three crust corner coupling heads

Technical field

The application belongs to technical field of ship transportation, particularly relates to a kind of three crust corner coupling heads.

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 three crust corner coupling heads, 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 three crust corner coupling heads, comprise polytetrafluoroethylene sponge core, and the rubber epidermis that three bread cover is formed to described sponge core, described sponge core comprises straight the first noumenon, and be the second body of 120 ° of angles with described the first noumenon, the end of described the first noumenon is connected with the end of described second body, a sector space is formed between described the first noumenon and the second body, described sponge core has the main part of rectangular in cross-section, and be the convex extension part of isosceles trapezoid from the cross section that described main part protrudes out in described sector space, described rubber epidermis comprises the first epidermis being coated on described main part bottom surface, be coated on the second epidermis of described main part side, and be coated on the 3rd epidermis of side, described convex extension part.

Preferably, in three above-mentioned crust corner coupling heads, the surface of described first epidermis forms zig-zag.

Preferably, in three above-mentioned crust corner coupling heads, the surface of described second epidermis forms zig-zag.

Preferably, in three above-mentioned crust corner coupling heads, between described first epidermis and described sponge core, magnet is provided with.

Preferably, in three above-mentioned crust corner coupling heads, be connected by mucilage layer between described sponge core with described epidermis.

Preferably, in three above-mentioned crust corner coupling heads, 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 three crust corner coupling heads in the utility model specific embodiment;

Figure 2 shows that the lateral plan of three crust corner coupling heads 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, three crust corner coupling heads comprise polytetrafluoroethylene sponge core 1, and the rubber epidermis 2 that three bread cover is formed to sponge core, sponge core comprises straight the first noumenon 11, and be the second body 12 of 120 ° of angles with the first noumenon, the end of the first noumenon 11 is connected with the end of the second body 12, a sector space 13 is formed between the first noumenon 11 and the second body 12, sponge core 1 has the main part 14 of rectangular in cross-section, and the cross section that protrudes out in sector space 13 of main body is the convex extension part 15 of isosceles trapezoid, rubber epidermis 2 comprises the first epidermis 21 being coated on main part bottom surface, be coated on the second epidermis 22 of main part 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.
