Abstract
The utility model discloses a sealing structure, include mouthful frame (1) and be used for the lid to close flap (2) on the mouth frame (1) both ends that flap (2) and mouthful frame (1) lid closed be equipped with a pair of each other for the composite seal pad of joint, the composite seal pad is including sealed pad (3) of two reverse dislocation set on flap (2) bottom and mouthful frame (1) upper portion. The utility model discloses simple structure, sealed effectual, life is longer, and the installation is more convenient with the change.
Description
Technical field
This utility model relates to aeroplane structure design, particularly relates to a kind of sealing structure.
Background technology
Aeroplane structure design offers all kinds of lid or hatch door often on body, to meet the demands such as working service.In order to
Meet the design seal request to be met of requirement, lid or the hatch doors such as body anticorrosion, i.e. lid or hatch door be can open or
The molectron of dismounting, its sealing is different from the sealing of fixed structure, and it is that the elastic compression by sealing member realizes, various
Under service condition, its sealing member should be at even resilient compressive state, therefore general lid seal form seals frequently with rubber cushion.
Using rubber cushion to seal is most widely used lid or hatch door seal form, and conventional fluid sealant is lined with aviation offset plate
Cutting and vulcanization in situ two kinds, the form that both seal gaskets are conventional is certain thickness slab construction, slab construction close
Packing form is limited due to decrement so that be effectively in sealing contact area certain, simultaneously because slab construction sealing gasket itself
Construction features, causes once subgasket edges generation seepage, then seals on whole sealing surface and will lose efficacy, pacifies to aircraft flight
Complete and body is safeguarded and is hidden some dangers for.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to reality need, it is provided that a kind of sealing structure.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of sealing structure, including mouthful frame with for covering the lid on described mouth frame, at described lid and mouth frame lid
The two ends closed are provided with the combination sealing pad of a pair clamping each other, and described combination sealing pad includes that two reversely shift to install in lid
Bottom and the sealing gasket on mouth frame top.
The two ends up and down of described combination sealing pad are bonding with bottom lid and mouth frame top respectively.
Described sealing gasket includes a flat part and clamping part, and the bottom of the flat part of sealing gasket is adhesive portion, described buckle
Portion is arranged by several oblique sawtooth gaps longitudinally convex on flat part top and is formed.
This utility model simple in construction, good sealing effect, service life is longer, installs and change more convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model combination sealing pad；
Fig. 3 is the structural representation of this utility model sealing gasket.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
Embodiment: see Fig. 1-3.
A kind of sealing structure, including mouthful frame 1 with for covering the lid 2 on described mouth frame 1, at described lid 2 and mouth
The two ends that frame 1 covers are provided with the combination sealing pad of a pair clamping each other, and described combination sealing pad includes that two reversely shift to install
Bottom lid 2 and the sealing gasket 3 on mouth frame 1 top.
The two ends up and down of described combination sealing pad are bonding with bottom lid 2 and mouth frame 1 top respectively.
Described sealing gasket 3 includes that a flat part and clamping part, the bottom of the flat part of sealing gasket 3 are adhesive portion, described card
Button portion is arranged by several oblique sawtooth gaps longitudinally convex on flat part top and is formed.
As it is shown on figure 3, this gasket structure form is disposed with three protruding oblique sawtooth uniformly at its length direction
Bar, in tiltedly " mountain " font.
This gasket structure is installed as illustrated in fig. 1 and 2, when actual installation uses, and need to be by the sealing gasket 3 of two pieces same size
Respectively by adhesive paving in the lid 2 needing sealing and mouth frame 1, it may be noted that distinguish on lid 2 and mouth frame 3 during installation
Its sawtooth incline direction of sealing gasket 3 pasted is wanted reversely.
When this sealing gasket is installed consistent with the position dimension of sealing gasket 3 on mouth frame 1 due to lid 2, and the saw on sealing gasket 3
Tooth is oblique sawtooth, as long as so applying uniform pressure in lid, the sealing gasket 3 cooperated can easily be engaged, and seals
The deformation extent of pad 3 is directly proportional to executing stressed size, and the deformation of the biggest sealing gasket 3 of pressure is the biggest, in lid 2 and lid 4
The occlusion of sealing gasket is the tightst, is the most effectively in sealing contact area the biggest, and sealing effectiveness is the best；Owing to this gasket material is
Caulking gum, its characteristic determines this sealing gasket 3 and has good elastic compression performance, after pressure is cancelled, has preferably recovery
Ability
Depending on form of packers and size can be according to specifically used situations, such as along the oblique sawtooth of sealing gasket 3 length direction
Quantity can change into two or other, the height of sawtooth and other sizes all can be made by oneself according to service condition.
Claims (3)
1. seal a structure, including a mouthful frame (1) be used for covering the lid (2) on described mouth frame (1), it is characterised in that
