Left plate and the step-like outer rim shape of right plate be adapted it is step-like, wherein, the left side edge of the pedal and the left side
The outer rim of plate by mortise-tenon joint, the outer rim of the right side edge of the pedal and the right plate by mortise-tenon joint, in addition,
The pedal is connected with the mortise-tenon joint of the left plate and right 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 plate
Groove, the tongue-and-groove uniformly to distribute alternately and tenon being adapted are offered on the left and right sides edge of the pedal.
The utility model has the advantage of：
Airstair of the present utility model, attachment structure stability is stronger, also, in the premise for meeting use intensity requirement
Under, the weight of cabin door structure is greatly reduced, improves the economy that hatch door uses.

Embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Accompanying drawing in embodiment, the technical scheme in the embodiment of the utility model is further described in more detail.In the accompanying drawings, from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Described reality
It is the utility model part of the embodiment to apply example, rather than whole embodiments.Below with reference to the embodiment of accompanying drawing description
It is exemplary, it is intended to for explaining the utility model, and it is not intended that to limitation of the present utility model.It is new based on this practicality
Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belong to the scope of the utility model protection.Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " is based on accompanying drawing institutes
The orientation or position relationship shown, it is for only for ease of description the utility model and simplifies description, rather than indicates or imply and be signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The limitation of novel protected scope.
1 to Fig. 4 airstair of the present utility model is described in further details below in conjunction with the accompanying drawings.
The utility model provides a kind of airstair, including left plate 11, right plate 12 and pedal 2.
Left plate 11 is made up of composite；The outer rim of the side of left plate 11 (lower left side in Fig. 1) is curved, is applicable with pre-
The profile of aircraft door match；The outer rim of the opposite side relative with arcing outer edges (upper right side in Fig. 1) is on left plate 11
It is step-like.
Right plate 12 is made up of composite；The shapes and sizes of right plate 12 are identical with left plate 11, right plate 12 with
Left plate 11 is parallel to each other and is symmetrical arranged.
Pedal 2 is made up of composite；Pedal 2 is in multistage bending, and its left and right sides edge is shaped to and left plate
11 and the step-like outer rim shape of right plate 12 be adapted it is step-like；Wherein, the left side edge of pedal 2 and the outer rim of left plate 11
By mortise-tenon joint, the right side edge of pedal 2 and the outer rim of right plate 12 are by mortise-tenon joint, in addition, in pedal 2 and left plate
11 are connected with the mortise-tenon joint of right plate 12 by co-curing, so as to form airstair structure.
It should be noted that left plate 11, right plate 12 and pedal 2 can use known a variety of suitable composite woods
Material is formed, and there is honeycomb inside；Also, company is fixed by co-curing molding mode again in the opening position by mortise-tenon joint
