Description
Technical field
The present invention relates to the design of aircraft door structure, in particular to a kind of airstairs.
Background technique
Airstairs of airplane is the aircraft proximity device to go on or off the plane for boarding personnel.Current Airstairs of airplane is especially
Door ladder unification landing gate airstair considerably increases the weight of boarding door mostly using metal structure；In addition, stepping on
Connection between each part of machine ladder causes airstair to can not meet intensity requirement there is also unreasonable defect is connected.
Summary of the invention
The object of the present invention is to provide a kind of airstairs, to solve the problems, such as at least one existing for existing airstair.
The technical scheme is that
A kind of airstair, comprising:
Left plate is made of composite material, and the outer rim of the left plate side is arc-shaped, with pre- applicable aircraft door
Shape matches, and the outer rim of the other side opposite with the arcing outer edges is in step-like on the left plate；
Right side plate is made of composite material, and the shapes and sizes of the right side plate are identical as the left plate, the right side
Plate is parallel to each other and is symmetrical arranged with the left plate；
Pedal is made of composite material, the pedal be in multistage bending, left and right sides edge be shaped to it is described
Left plate and the step-like outer rim shape of right side plate are compatible step-like, wherein the left side edge of the pedal and the left side
The outer rim of plate passes through mortise-tenon joint by mortise-tenon joint, the right side edge of the pedal and the outer rim of the right side plate, in addition,
The pedal is connect at the mortise-tenon joint of the left plate and right side plate by co-curing.
Preferably, the tenon and tenon uniformly to distribute alternately is offered in the step-like outer rim of the left plate and right side plate
Slot offers the compatible tongue-and-groove and tenon uniformly to distribute alternately in the left and right sides edge of the pedal.
The present invention has the advantages that
Airstair of the invention, connection structure stability is stronger, also, under the premise of meeting use intensity requirement, pole
The weight for reducing cabin door structure greatly, improves the economy that hatch door uses.

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.Under
Face is described in detail the embodiment of the present invention in conjunction with attached drawing.
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.
1 to Fig. 4 airstair of the invention is described in further details with reference to the accompanying drawing.
The present invention provides a kind of airstairs, including left plate 11, right side plate 12 and pedal 2.
Left plate 11 is made of composite material；The outer rim of 11 side of left plate (lower left side in Fig. 1) is arc-shaped, is applicable in pre-
The shape of aircraft door match；The outer rim of the other side opposite with arcing outer edges (upper right side in Fig. 1) is on left plate 11
It is step-like.
Right side plate 12 is made of composite material；The shapes and sizes of right side plate 12 are identical as left plate 11, right side plate 12 with
Left plate 11 is parallel to each other and is symmetrical arranged.
Pedal 2 is made of composite material；Pedal 2 is in multistage bending, and left and right sides edge is shaped to and left plate
11 is compatible step-like with the step-like outer rim shape of right side plate 12；Wherein, the outer rim of the left side edge of pedal 2 and left plate 11
By mortise-tenon joint, the right side edge of pedal 2 and the outer rim of right side plate 12 are by mortise-tenon joint, in addition, in pedal 2 and left plate
11 are connected at the mortise-tenon joint of right side plate 12 by co-curing, to form airstair structure.
It should be noted that left plate 11, right side plate 12 and pedal 2 can use known a variety of suitable composite woods
Material is constituted, and there is honeycomb in inside；Also, passes through co-curing molding mode again at the position by mortise-tenon joint and company is fixed
It connects, so that connection structure stability is stronger, thus the economy used in the weight and raising hatch door for greatly reducing cabin door structure
Property under the premise of, moreover it is possible to meet use intensity requirement.
Further, at the mortise-tenon joint of pedal 2 and left plate 11 and right side plate 12, it can be and tenon is set on pedal 2
First 31, matched tongue-and-groove 32 is set on left plate 11 and right side plate 12；Of course, it can be reversed；In the present embodiment, exist
On pedal 2 or left side plate, spacing is smaller between two tenons 31, so that indirect forming is a tongue-and-groove 32, so similar
It is spaced apart form in what a tenon 31 connect a tongue-and-groove 32, the stability of connection structure can be further strengthened.
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-.
