Description
Technical field
The present invention relates to technical field of aircraft structure design, in particular to airplane hatch cover rotational hinge means.
Background technique
It commonly safeguards that lid connection type is hinge-type connection type on aircraft engine nacelle at present, is to close two panels
Page is connected in lid and structural body, which has the drawback that
1, the notch that hinge poker need to be reserved in structure, it is not good enough to cause leakproofness；
2, the p-type head of hinge can protrude theoretical contoured surface, influence local pneumatic performance.
Summary of the invention
To overcome above-mentioned at least one defect of the existing technology, the present invention provides a kind of airplane hatch cover turning joints
Device, including hinge and hinge covering, right leaf of hinge and the fuselage mouth frame of hinge are mutually fixed, and hinge covering is integrally formed knot
Structure, both ends are respectively the first covering section and third covering section, are the second covering section among the first covering section and third covering section,
First covering section is mutually fixed in tabular and with the left leaf of hinge of hinge, and third covering section is mutually fixed in tabular and with lid.
Preferably, the two sides of the second covering section and third covering section are fixed with hinge stud.
Preferably, the second covering section section is arc-shaped, and amount of deflection is determined according to the opening angle of lid.
Airplane hatch cover rotational hinge means provided by the invention, have the following beneficial effects:
1, without accessory structures parts such as additional supports and rocker arm, and be not required to increase in structural body and lid it is extra
Notch can guarantee the leakproofness of lid and the maximization of opening angle；
2, traditional lid connection type is solved in the contradiction of leakproofness and occupancy inner space, while the device is not also dashed forward
Theoretical shape out, the system distance structure of being able to solve is relatively close and the connectivity problem of the maintenance lid that has seal request.

Specific embodiment
To keep the purposes, technical schemes and advantages of the invention implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention is further described in more detail.In the accompanying drawings, identical from beginning to end or class
As label indicate same or similar element or element with the same or similar functions.Described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that, term " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown, is merely for convenience of description of the present invention and simplification of the description, rather than the dress of indication or suggestion meaning
It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as protecting the present invention
The limitation of range.
Below by specific embodiment, the present invention is described in further detail.
Specific embodiment:
The present invention provides a kind of rotational hinge means for airplane hatch cover as shown in Figure 1, maying be used at quick-release type dimension
The connecting portion of retaining lid comprising hinge 1 and hinge covering 2, hinge 1 preferably use 2A12-T4-XC01-6 duralumin, hard alumin ium alloy material
Material production, hinge covering 2 are preferably made of 2A12-O aluminum alloy materials, and hinge 1 includes left leaf of hinge 11 and right leaf of hinge 12,
Hinge covering 2 is an integral molding structure, and one end is the first covering section 21, and the other end is third covering section 23, the first covering section
21 and third covering section 23 among be the second covering section 22；
As shown in Fig. 2, the right leaf of hinge 12 of hinge 1 is fixed with 5 phase of fuselage mouth frame, the first covering section 21 in tabular and with
11 phase of left leaf of hinge of hinge 1 is fixed, and is preferably fixed using riveting method, third covering section 23 in tabular and with lid 4
It is mutually fixed, preferably use countersunk head high locked bolts to fix；
In the present embodiment, 22 section of the second covering section is arc-shaped, and amount of deflection is determined according to the opening angle of lid 4, and the
The two sides of two covering sections 22 and third covering section 23 are respectively and fixedly provided with hinge stud 3, and hinge stud 3 has been used for rigid support effect,
Preferably, hinge stud 3 is fixed on 23 two sides of the second covering section 22 and third covering section by riveting method.
When opening lid 4, first lid 4 is unlocked, then outwardly opens lid 4, as shown in figure 3, hinge covering 2 at this time
It is rotated around hinge 1, realizes the rotation of lid 4, when hinge covering 2 is mutually touched with the edge of fuselage mouth frame 5, lid 4 reaches most
Big aperture, the position of hinge 1, the amount of deflection of the second covering section 22, lid 4 be in close state under when hinge 1 aperture etc. be
It is determined according to the opening angle of 4 design requirement of lid.
Compared with existing maintenance lid interconnection technique, the rotational hinge means are before occupying smaller structure inner space
It puts, has both met sealing structure and pneumatic shape requirement, in turn ensure opening angle, while structure type is simple, and weight
Gently, to the adaptable of shape, it is highly suitable for that system distance structure is relatively close and the connection of the maintenance lid that has seal request；And
And the rotational hinge means have been applied during Mr. Yu's large transport airplane develops, and are approved and favorable comment to have very strong general
Property and practicability, can be applied to the connecting portion of the military-civil aircraft maintenance lid of each model.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be with the scope of protection of the claims
It is quasi-.
