Description
Technical field
The utility model relates to aeroplane structure design, specifically a kind of hinge arrangement for airplane hatch cover.
Background technique
It is well known that in aircraft maintenance, it usually needs lid is opened, and opening lid needs lid overturning centainly
Exterior space.Existing maintenance lid uses hinge-type or articulated connecting mode mostly, and the space needed is opened in lid overturning
Greatly.And limited by aircaft configuration space, such as the maintenance lid arranged on aircraft engine nacelle, because the exterior space morning limits
System prevents to repair lid from fully opening, causes certain difficulty to maintenance.
Existing hinge structure, there is usually one central axises, and the space that nacelle of airplane position is opened for lid is limited.
Summary of the invention
The application's is designed to provide a kind of hinge arrangement for airplane hatch cover, can greatly reduce lid and open institute
The exterior space needed.
A kind of hinge arrangement for airplane hatch cover, which is characterized in that the hinge arrangement contain linkage block, left leaf of hinge,
Right leaf of hinge and pin shaft, the linkage block are a rectangle structures, and linkage block upper surface is longitudinally asymmetric, and centre is plane two
Side is inclined-plane, the lower surface of linkage block be equipped with two column protrusion spaced linkage hinge holes, the left leaf of hinge and
It is respectively equipped with spaced hinge hole corresponding with linkage hinge hole on the inside of right leaf of hinge, separately has pin shaft by left leaf of hinge
Hinge hole is connect with the linkage hinge hole on the left of linkage block lower surface, and there are one pin shafts by the hinge hole of right leaf of hinge and to link
Linkage hinge hole connection on the right side of block lower surface.
Above-mentioned hinge arrangement when in use, by left leaf of hinge and have with blade by a side of lid with it is corresponding
The connection of mouth frame side.
The application belongs to aircraft engine nacelle component, using in aircraft engine nacelle structure quick-release type maintenance lid
Connecting portion.Two panels hinge is connected in lid and structural body by it.When lid open when, two combination hinges rotating around
Each axis of rotation rotation, to realize the unlatching of lid.The rotational hinge means are not take up inside configuration space, and structure type simply may be used
It leans on, light-weight, good rigidity, and the opening angle of lid can be greatly increased, very the closer large scale of applicable system distance structure
Safeguard the connection of lid.
The beneficial effects of the present application are as follows: 1) hinge arrangement there are two folding hinge axis, has lid and rolls over twice
Folded possibility reduces the overturning radius of lid, has saved opening space；2) when lid is opened, first by being connect with lid
Side leaf of hinge and linkage block generate folding, then second fold is occurred by the hinge of the linkage block other side, lowered significantly
The overturning radius of lid reduces the space opened and needed.3) two panels hinge is connected by linkage block and is used by the application, hair
It is limited not to solve traditional lid connection type opening angle for the advantages of having waved hinge-type and two kinds of connection types of hinge type
Foot, while the device does not also protrude theoretical shape, is able to solve the connectivity problem of the closer maintenance lid of system distance structure.4)
It is simple and reasonable, convenient for manufacture.
Attached drawing is described in further detail the application with reference to embodiments.
Detailed description of the invention
Fig. 1 is hinge arrangement installation diagram
Fig. 2 is hinge arrangement schematic diagram
Fig. 3 is to connect airplane hatch cover schematic diagram using hinge arrangement
Explanation: 1 linkage block, 2 left hinges, 3 right hinges, 4 linkage hinge holes, 5 pin shafts, 6 stiffening plates, 7 hinges is numbered in figure
Hole, 8 lids, 9 mouthfuls of frames.
Specific embodiment
Referring to attached drawing, the hinge arrangement of the application contains linkage block 1, left leaf of hinge 2, right leaf of hinge 3 and two pin shafts
5, the linkage block 1 is a rectangle structure, and 1 upper surface of linkage block is longitudinally asymmetric, and it is inclined-plane that centre, which is plane two sides, is being joined
Spaced linkage hinge holes 4 of the lower surface of motion block 1 equipped with two column protrusions, the left leaf of hinge 2 and right leaf of hinge 3
Inside is respectively equipped with spaced hinge hole 7 corresponding with linkage hinge hole, separately has pin shaft 5 by the hinge hole 7 of left leaf of hinge 2
It is connect with the linkage hinge hole 4 on the left of 1 lower surface of linkage block, there are one pin shafts 5 by the hinge hole 7 of right leaf of hinge 3 and to link
Linkage hinge hole 4 on the right side of 1 lower surface of block connects.
In implementation, in order to guarantee the intensity of linkage block 1, in the middle part of the lower surface of the linkage block 1, two column protrusion interval rows
It is longitudinally inlaid with a stiffening plate 6 between the linkage hinge hole 4 of column, rigid support is served to entire hinge leaf.
Above-mentioned hinge arrangement is by left leaf of hinge 2 and right leaf of hinge 3 by a side of lid 8 and corresponding mouth frame 9
Side connection.
The hinge hinge connects lid with mouth frame, as shown in figure 3, locked in use, triggering the lid being mounted in lid,
Two sides leaf of hinge is rotated rotating around respective pin shaft, realizes the unlatching of lid.
Claims (2)
