Abstract

The utility model discloses a kind of high strength rubber seal, described high strength rubber seal comprises: jacket layer, this jacket layer has the sealing surface portion that the flat bottom surface sections of outer surface and outer surface are cambered surface, and this jacket layer has hollow cavity, simultaneously, this bottom surface is provided with the dovetail card article that trend is same as the trend of this jacket layer, and this jacket layer adopts rubber-plastics material preparation; Packed layer, this packed layer is filled in this hollow cavity, and this packed layer is bipeltate preparation.The utility model has the advantages that: sealing effect is better, tensile strength is larger, and be easy to fix.

Description

High strength rubber seal
Technical field
The present invention relates to Sealing technical field, especially relate to a kind of high strength rubber seal.
Background technique
Rubber seal is as modal Sealing, its rubber-plastics materials that adopt are prepared as solid strip more, thereby slightly inadequate in intensity, and on sealing effect, also have deficiency, then when assembling, very easily there is situation about breaking, be in use easy to occur poorly sealed situation.Meanwhile, sealing bar adopts the mode of extruding to fix more, comparatively inconvenience.
Summary of the invention
The object of this invention is to provide a kind of high strength rubber seal, it has, and sealing effect is better, tensile strength is larger, and is easy to fixing feature.
The technical solution adopted in the present invention is: high strength rubber seal, and described high strength rubber seal comprises:
---jacket layer, this jacket layer has the sealing surface portion that the flat bottom surface sections of outer surface and outer surface are cambered surface, and this jacket layer has hollow cavity, simultaneously, this bottom surface is provided with the dovetail card article that trend is same as the trend of this jacket layer, and this jacket layer adopts rubber-plastics material preparation;
---packed layer, this packed layer is filled in this hollow cavity, and this packed layer is bipeltate preparation.
The material of preparing of described jacket layer is a kind of in EPDM, CR, EVA, SBR, NBR.
In described bottom surface sections, be penetrated with the steel wire that trend is same as the trend of this jacket layer.
The advantage that the present invention has is: sealing effect is better, tensile strength is larger, and is easy to fix.The fine and close rubber and plastic of high strength rubber-plastic sealing strip adoption of the present invention, as skin, makes it have higher tensile strength; Adopt bipeltate to fill as inside, make it have good elasticity and then there is good sealing effect; Adopt dovetail card article and need installation position to engage, being then convenient to fix.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the master of embodiments of the invention looks sectional view.
In figure: 10, jacket layer, 11, bottom surface sections, 12, sealing surface portion, 13, hollow cavity, 14, dovetail card article; 20, packed layer; 30, steel wire.
Embodiment
Embodiment, as shown in Figure 1: high strength rubber seal, comprises jacket layer 10 and packed layer 20.Wherein:
This jacket layer 10 has the sealing surface portion 12 that outer surface flat bottom surface sections 11 and outer surface are cambered surface, and this jacket layer 10 has hollow cavity 13.Meanwhile, this bottom surface 11 is provided with the dovetail card article 14 that trend is same as the trend of this jacket layer 10.So-called dovetail card article 14 refers to the card article that section is dovetail.Certainly, use the dovetail draw-in groove that position must be provided with and this dovetail card article 14 matches of sealing bar.In use, only need this dovetail card article 14 to be stuck in this dovetail draw-in groove and to have realized fixing of sealing bar, very convenient.And this jacket layer 10 adopts rubber-plastics material preparation.This rubber-plastics material can be a kind of in EPDM, CR, EVA, SBR, NBR.These rubber-plastics materials have good elasticity and compactness, have then increased to a certain extent the tensile strength of sealing bar.
This packed layer 20 is filled in this hollow cavity 13, and this packed layer 20 is bipeltate preparation.Like this, make the outer surface of sealing face 12 remain good original shape, increased the sealing effect of sealing bar.
Further say, in this bottom surface sections 11, be penetrated with at least 1 steel wire 30 that trend is same as the trend of this jacket layer 10.Like this, the tensile strength of sealing bar is had been further upgraded.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
