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.
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.
The utility model is described in further detail below by specific embodiment.
Specific embodiment：
As shown in Figures 2 to 4, the angle section is one to the angle section of connection aircraft hanging leading edge heat insulation structural provided by the utility model
Forming structure, it includes the first fixed part 1 and the second fixed part 2, and the junction of the first fixed part 1 and the second fixed part 2 is
Knuckle；
As shown in fig. 6, the angle section is fixed at the gap between thermal insulation board 3 and dividing plate 4, the first fixed part 1 is plate-like, its
With bending section, the bending section is located substantially at the centre position of the first fixed part 1, and concrete shape designs as needed, this reality
Apply in example, the first fixed part 1 of the bending section both sides is slab construction；First fixed part 1 with bending external form every
The fitting contact of the outer surface of hot plate 3, the bending section of the first fixed part 1 and the bending outer surface of thermal insulation board 3 are adapted, heat-insulated for making
Seal seamless between plate 3 and dividing plate 4, the first fixed part 1 is fixed on the outer surface of thermal insulation board 3 by rivet, the second fixed part 2
In tabular, it is located at the side edge of the first fixed part 1 and has certain angle between the first fixed part 1, and first is solid
