Abstract
The utility model provides an airplane cabin door sealing structure which comprises a cabin door body and a cabin door frame, wherein an elastic sealing strip with a connecting seat is inlaid at the inner side close to the edge of the cabin door body; the cross section of the elastic sealing strip is hollow circular; and a rigid sealing convex strip with the T-shaped cross section is fixed on the corresponding edge of the cabin door frame. In order to ensure convenient installation of the elastic sealing strip, a profile with a connecting slot is fixed at the inner side close to the edge of the cabin door body, and the connecting seat of the elastic sealing strip is inlaid in the connecting slot of the profile.
Description
Technical field
The utility model relates to the aeroplane structure design technical field, is particularly suitable for the aircraft door hermetically-sealed construction.
Background technology
Aircraft door especially passenger plane hatch door must have good sealing property, to guarantee keeping certain atmospheric pressure in the aircraft cabin.If aircraft accident appears in gas leakage possibly, this just needs the aircraft door favorable sealing property.At present, it is the flat seal contact that the aircraft door hermetically-sealed construction adopts, promptly by elastic packing band that is fixed on hatch door one side and the flat seal bar crimping sealing that is fixed on hatch door frame one side.This sealing, air flow direction if the somewhere elastic pressure diminishes a bit, just occur phenomenons such as light leak, gas leakage only by a direction easily.When assembling is made, solve top problem, need be very high to matching requirements, tolerance is very little when requiring to dock between hatch door and the hatch door frame, often will constantly adjust the link position of hatch door installation position.Even after adjusting, the excessive defective of hatch door jump still appears in a lot of hatch doors, influences the aircraft image appearance.It is too big to occur the band pretightning force simultaneously, problems such as switch hatch door effort.These problems have a strong impact on the designing quality and the assembly quality of aircraft door.
Summary of the invention
The utility model provides a kind of hatch door hermetically-sealed construction, and light leak, gas leak phenomenon when having overcome prior art middle deck door sealing have reduced design defect and the hatch door sealing manufacture deviation requirement high to the hatch door manufacture process requirement.
A kind of aircraft door hermetically-sealed construction contains hatch door body and hatch door frame, and the cross section that is inlaid with the band Connection Block in the proximal edge inboard of hatch door body is the elastic packing band of hollow circular, and being fixed with the cross section on the corresponding sides of hatch door frame is the rigid seal raised line of T type.
In order to make the elastic packing band easy for installation, be fixed with the section bar of a band link slot in the proximal edge inboard of hatch door body, the Connection Block of elastic packing band is embedded in the link slot of this section bar.
When hatch door was closed, T type sealed batten withstood the elastic packing band, made elastic packing band generation deformation, formed the contact surface of a dark U type between elastic packing band and the T type sealed batten.The seal form that directly is attached to the cushion block plane with traditional elastic packing band is compared, the deflection of elasticity band increases in this curved surface seal form, contact area between elastic packing band and the T type sealed batten increases, increased the tortuosity of gas flow, reduced the probability that air-flow flows out from contact surface between elastic packing band and the T type sealed batten, the gas permeation probability is very little, reaches the good sealing effectiveness of aircraft door, light leak, gas leak phenomenon when having solved the hatch door sealing.Reduced elastic packing band normal pressure simultaneously, made the switch hatch door more laborsaving.
Light leak, gas leak phenomenon when advantage of the present utility model is to solve the sealing of present hatch door have reduced design defect and the hatch door sealing manufacture deviation requirement high to the hatch door manufacture process requirement, make the switch hatch door more laborsaving simultaneously.
Below with reference to the embodiment accompanying drawing this application is described in further detail.

Number description: the curved part 9 Connection Block 10T type sealed battens of the curved part 7 cushion blocks 8 hatch door edge plates of 1 hatch door body, 2 hatch door frames, 3 elastic packing bands, 4 section bars, 5 fluid sealants, 6 hatch door side plates
The specific embodiment
Referring to accompanying drawing, as shown in Figure 1, the aircraft door hermetically-sealed construction comprises hatch door body 1 and hatch door frame 2, the cross section that is inlaid with band Connection Block 9 in the proximal edge inboard of hatch door body 1 is the elastic packing band 3 of hollow circular, the proximal edge inboard of hatch door body 1 is fixed with the section bar 4 of a band link slot, the Connection Block 9 of elastic packing band 3 is embedded in the link slot of section bar 4, section bar 4 both sides are fixed on the curved part 6 of hatch door side plate with fluid sealant 5, the other end of elastic packing band 3 is equipped with T type sealed batten 10, and curved part 8 of hatch door edge plate and 10 of T type sealed battens are equipped with cushion block 7.
As shown in Figure 2, elastic packing band 3 is identical with the shape of hatch door frame 2 with form in the installation site of aircraft door body 1, and has the theoretical profile of aircraft.
When hatch door was closed, T type sealed batten 10 withstood elastic packing band 3, made elastic packing band 3 that deformation take place, and formed the contact surface of a dark U type between elastic packing band 3 and the T type sealed batten 10.The seal form that directly is attached to the cushion block plane with traditional elastic packing band is compared, the deflection of elasticity band 3 increases in this curved surface seal form, contact area between elastic packing band 3 and the T type sealed batten 10 increases, increased the tortuosity of gas flow, reduced the probability that air-flow flows out from contact surface between elastic packing band 3 and the T type sealed batten 10, the gas permeation probability is very little, reaches the good sealing effectiveness of aircraft door, light leak, gas leak phenomenon when having solved the hatch door sealing.Reduced elastic packing band normal pressure simultaneously, made the switch hatch door more laborsaving.
Claims (2)
1. hatch door hermetically-sealed construction, contain hatch door body and hatch door frame, the cross section that it is characterized in that being inlaid with in the proximal edge inboard of hatch door body the band Connection Block is the elastic packing band of hollow circular, and being fixed with the cross section on the corresponding sides of hatch door frame is the rigid seal raised line of T type.
2. hatch door hermetically-sealed construction as claimed in claim 1 is characterized in that being fixed with a section bar of being with link slot in the proximal edge inboard of hatch door body, and the Connection Block of elastic packing band is embedded in the link slot of this section bar.
