Description
Technical field
The utility model relates to a kind of compound sealing strip for sealing.
Background technology
Sealing strip is for connection between object sealing, prevents leakage, realizing airtight common component.
Existing seal is typically to utilize the elasticity (such as elastic caoutchouc) of material or seal configuration design produced
Elasticity, makes seal produce elastic deformation at object linkage interface, fills out the gap of object linkage interface
Fill, block, it is achieved the purpose of sealing.
Existing seal exists following not enough: firstly, since the structure design of seal often can only produce one
Level elastic deformation, its deflection is limited, and elastic properties of materials is decided by the character of material, conventional elastic caoutchouc
Deflection is also limited, therefore, between utilizing elastic properties of materials and structural elasticity often to object linkage interface
Gap can not accomplish completely reliable filling and closure, and particularly coarse in seal interface, surface size error is relatively
Big object linkage interface, such as the linkage interface etc. of fabric structure, situation is especially true；Secondly, to even
Connect object to carry out sealing and mainly realize gas and the isolation of liquid (mainly water), for gas,
Under the state that there is not negative pressure with the external world in sealer, even if there is minim gap in seal interface, owing to sealing
There is not pressure reduction in both sides, interface, will not produce gas flowing in sealer with the external world；But, when sealer
During the affair water of seal interface, due to the effect of tension force in the table of water, the water outside seal interface can be along sealing boundary
The minim gap in face seepage in seal interface, causes seal failure., surface chi coarse for seal interface
The object linkage interface that very little error is bigger, such as the linkage interface etc. of fabric structure, uses existing seal to enter
Row seals, and the possibility producing leakage is bigger.
Utility model content
The technical problems to be solved in the utility model is, it is provided that a kind of compound sealing strip, overcomes existing compound

It is characterized in that, including the body extended along this sealing strip length direction and waterproof layer, this body is by elastic material
Material is made, and this waterproof layer is made up of water-swellable elastomeric material, and this body includes that described compound sealing strip is symmetrical
Arrange, matching surface when using in pairs and relative with this matching surface and by sealed object installation site table
The installation sealing surfaces that face coordinates；
This waterproof layer is arranged on the matching surface of this body, and is connected as an entirety with this body；
Described body includes extending along described sealing strip length direction, be arranged on it install on sealing surfaces recessed
Groove, extend along described sealing strip length direction, be arranged on its matching surface and it is installed between sealing surfaces
Through hole.
In compound sealing strip of the present utility model, described groove is two or more, along described installation enclosed watch
The width interval in face is arranged.
In compound sealing strip of the present utility model, described through hole is two or more, along described compound sealing strip
Width interval arrange.
In compound sealing strip of the present utility model, on the cross section of this compound sealing strip, described installation is close
The angle a of the two sides that envelope surface is adjacent is the obtuse angle less than or equal to 105 ° of degree.
In compound sealing strip of the present utility model, described angle a installs less than or equal to described compound sealing strip
Described by the side Self-locking angle of sealed object installation site.
In compound sealing strip of the present utility model, including being arranged on two adjacent with described installation sealing surfaces
Anticreep tongue on side, this anticreep tongue along this compound sealing strip length direction extend, its incline direction and its
The incline direction of side, place is identical.
Implementing compound sealing strip of the present utility model, compared with the prior art, it provides the benefit that:
1. the waterproof layer being made up of water-swellable elastomeric material by setting, and in the peace of weatherstrip body
Groove is set on dress sealing surfaces, sets between the matching surface and installation sealing surfaces of body
Put through hole, when making sealing strip pressurized, its structure can produce because of groove variations generation
Level elastic deformation and the two grades of elastic deformations produced because of thru-hole distortion, structural elasticity deflection is big,
Ensure the compound sealing strip sealing to being installed sealing strip position by sealed object；In seal interface
When meeting water, waterproof layer produces and expands, and makes to dock mutually two between two compound sealing strips of cooperation
Expanded rear the most mutually extruding between waterproof layer, further between raising two waterproof layers
Seal, thus improve the sealing reliability of sealing strip and waterproof reliability；
2. simple in construction, easily implements.
