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.
The utility model proposes a kind of airframe jack top pad, as shown in figure 1, including top pad body 1 and rubber
Circle 2, wherein, the top pad body 1 includes bulb part and column part, and the ball head is divided into curved surface and plane composition
Hemispherical configuration, the column part is arranged on the side with plane of the bulb part, and on the column part
Annular groove is provided with, the adaptation of rubber ring 2 is arranged in the annular groove.
With reference to figure 1, the diameter of section of the column part is less than the planar diameter of the bulb part, also, cylindrical portion
The diameter of section divided is consistent with the preformed hole internal diameter of aircraft fuselage structure 4, with reference to figure 2, so as to which the column part is stretched
Enter into the preformed hole, in the present embodiment, the use-case of the top pad first fills in the top Upper cylindrical of pad body 1 with reference to figure 2
In the reserved mounting hole of aircraft fuselage structure 4, until the upper end of the top bottom bulb of pad body 1 fully contacts with aircraft skin 3.It
