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.
The invention proposes a kind of aircraft wing jack top pads, as shown in Figures 1 and 2, including top pad body 1 and countersunk head
Screw 4, wherein be provided with through-hole on the top pad body 1, the through-hole include the lesser first part of internal diameter and internal diameter compared with
Big second part, the internal diameter of the first part is arranged to that the screw portion of the sunk screw 4 is allowed to pass through, and energy
The nut portion of the sunk screw 4 is enough prevented to pass through, the screw portion of the sunk screw 4 can pass through described first
Point, and lengthening section is extended with except prominent first part.
Fig. 2 gives the schematic diagram that uses of wing jack of the present invention top pad, and the screw rod of sunk screw passes through the of through-hole
After a part, it is screwed on wing by above-mentioned lengthening section.The top pad body 1 is metal material, has good hardness
