The invention belongs to a sealing technology, and in particular relates to a sealing structure of a composite motion surface. The sealing structure of the composite motion surface comprises a motion baffle plate, a pressing strip and a rubber sealing strip, wherein the rubber sealing strip comprises an installation edge, a first interference edge and a second interference edge, which are connected with one another; the installation edge of the rubber sealing strip is covered with the pressing strip; the installation edge of the rubber sealing strip and the pressing strip are fixed together to the free edge of the motion baffle plate; the second interference edge is shorter than the first interference edge; a certain intersection angle is formed between the first interference edge and the second interference edge; both the first interference edge and the second interference edge contact the composite motion surface. According to the sealing structure of the composite motion surface, friction force and pressing force can be reasonably distributed during motion, and the pneumatic tightness is ensured. The sealing structure of the composite motion surface has the advantages of good attachment, simplicity in assembly and less possibility of deformation, and is suitable for sealing of the edge of a large-curvature motion part.

Description

A kind of compound motion surface seal structure

Technical field

The invention belongs to packing technique, particularly about a kind of hermetically-sealed construction of compound motion face.

Background technology

Movable parts place at aircraft surfaces, need to realize pneumostop, when not protruding profile, guarantees the aeroperformance of aircraft.For example, some aircraft horizontal stabilizer need to carry out fine motion trim awing, opening when the root of horizontal stabilizer is provided with rectification baffle plate and blocks horizontal tail motion, thereby baffle plate need to move along with the deflection up and down of horizontal stabilizer, between baffle plate and vertical fin, there is gap, air-flow can enter vertical fin by gap, therefore need between baffle plate and vertical fin, design sealing arrangement, realizes pneumostop requirement when baffle plate can be moved smoothly.And some aircraft baffle plate oad is large, contain deep camber profile, during motion and vertical fin have friction, easily make rubber seal tape distortion or fold occur, can not fit with vertical fin well.The hermetically-sealed constructions such as traditional p-type material, T-shaped material can not meet the good result in above-mentioned situation, and in assembling and use, easily distortion, causes poorly sealed.

Summary of the invention

The object of the invention is: the hermetically-sealed construction that a kind of good sealing effect, on-deformable compound motion face are provided.

Technical scheme of the present invention is: a kind of hermetically-sealed construction of compound motion face, it comprises motion baffle plate, press strip, rubber weather strip, described rubber weather strip comprises mounting edge, the first interference edges, second interference edges of joining, wherein, the mounting edge of rubber weather strip covers and is fixed on together motion baffle plate free edge by press strip, the second interference edges length is less than the first interference edges, and between the two, forms certain angle of cut, and all contacts with compound motion face.

Described the first interference edges and mounting edge intersection have one for adjusting the depression of amount of interference.

Described the first interference edges reduces to tip thickness gradually from root.

The surface that described the first interference edges and the second interference edges contact with compound motion face is provided with the smooth anti-pad pasting that sticks up.

Described mounting edge root is provided with the boss of orientation movements baffle plate.

The second interference edges end is provided with arc angling.

Described motion baffle plate free edge is provided with the rubber weather strip of some splicings.

Advantage of the present invention is: the hermetically-sealed construction of compound motion face of the present invention is used the rubber seal section bar of a kind of " K " tee section, by press strip and fastener, be installed on the baffle edge that needs motion, by the boss of " K " section bar one side, realize location is installed, the interference surface of opposite side is realized sealing, the reasonable distribution of friction force and pressure while realizing motion by positioning boss platform and Cross section Design angle, guarantee pneumatic tightness, there is simple structure, convenient for production, be easy to install, laminating is good, on-deformable advantage, the edge seal that adapts to deep camber compound motion parts.

Accompanying drawing explanation

Fig. 1 is the front view of compound motion surface seal structure of the present invention;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the partial enlarged drawing of Fig. 2;

Fig. 4 is the section drawing of rubber weather strip,

Wherein, 1-motion baffle plate, 2-press strip, 3-rubber weather strip, 4-compound motion face, 5-mounting edge, 6-the first interference edges, 7-the second interference edges, 8-depression, 9-boss, 10-arc angling.

The specific embodiment

Below in conjunction with drawings and Examples, the present invention is described further:

Please refer to Fig. 1, Fig. 2, Fig. 3, compound motion surface seal structure of the present invention comprises motion baffle plate, press strip, rubber weather strip.

Refer to Fig. 4, described rubber weather strip comprises mounting edge, the first interference edges, second interference edges of joining, wherein, the mounting edge of rubber weather strip covers and is fixed on together motion baffle plate free edge by press strip, the second interference edges length is less than the first interference edges, and between the two, be formed with certain angle of cut, and all contact with compound motion face.

Described the first interference edges and mounting edge intersection have one for adjusting the depression of amount of interference.When motion baffle plate moves along compound motion face, this depression can, by amount of interference and the interference angle of first, second interference edges of fine setting, guarantee the smooth and easy and good seal of motion.

Described the first interference edges reduces to tip thickness gradually from root.Prevent motion baffle plate in thering is Fig. 4 during downward movement tendency the first interference edges there is volume and stick up.

The surface that described the first interference edges and the second interference edges contact with compound motion face is provided with smoothly anti-sticks up pad pasting, not only can strengthen the effect that prevents that volume from sticking up, friction force when its smooth surface also can reduce compound motion.

Described mounting edge root is provided with the boss of orientation movements baffle plate.Boss not only can be convenient to rubber strip location in installation process, power provides support when baffle plate has the movement tendency making progress in Fig. 4, make rubber strip in along with baffle plate motion process, reach the reasonable distribution of pressure and friction force, not yielding, and can contact well with motion contact surface at any time.

The second interference edges end is provided with arc angling, guarantees to contact with the smooth of motion contact surface, reduces friction.

Described motion baffle plate free edge is provided with the rubber weather strip of some splicings, and Mosaic face can be chosen in motion baffle plate profile curvature greatly and the more complicated position of shape, and rubber strip changes because distortion causes curvature, causes assemblage gap.

In sum, the rubber seal section bar of the present invention uses a kind of " K " tee section, by press strip, cover, be fixed on the baffle edge that needs motion, rely on the positioning boss of " K " section bar one side to realize profile location, first, second interference edges of opposite side realizes sealing, the reasonable distribution of friction force and pressure while realizing motion by boss and Cross section Design angle, amount of interference and interfere the fine setting of angle when the depression by between first, second interference edges realizes motion, guarantees the pneumatic tightness of whole motion process.There is simple structure, convenient for production, be easy to installation, good, the on-deformable feature of fitting, adapt to the edge seal of deep camber compound motion parts.
