Detailed description of the invention
Clearer, below in conjunction with this utility model for the purpose making this utility model implement, technical scheme and advantage
Accompanying drawing in embodiment, is further described in more detail the technical scheme in this utility model embodiment.In the accompanying drawings, ad initio
Represent same or similar element to same or similar label eventually or there is the element of same or like function.Described reality
Executing example is a part of embodiment of this utility model rather than whole embodiments.The embodiment described below with reference to accompanying drawing
It is exemplary, it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.New based on this practicality
Embodiment in type, the every other enforcement that those of ordinary skill in the art are obtained under not making creative work premise
Example, broadly falls into the scope of this utility model protection.Below in conjunction with the accompanying drawings embodiment of the present utility model is described in detail.
In description of the present utility model, it is to be understood that term " " center ", " longitudinally ", " laterally ", "front", "rear",
The orientation of the instruction such as "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " or position relationship are for based on accompanying drawing institute
The orientation shown or position relationship, be for only for ease of description this utility model and simplify description rather than instruction or hint indication
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The restriction of novel protected scope.
As shown in Figures 1 to 5, a kind of nipple for aircraft cargo bay floor, comprise fixed base 1 and serve as a contrast with screw thread
Set 2, fixed base 1 comprises cylinder 11 and base plate 12, and base plate 12 one end is fixed on cargo deck, the other end and cylinder
One end of 11 connects；Cylinder 11 is provided with female thread；Screw-thread bush 2 is provided with female thread and external screw thread, and screw-thread bush 2 passes through
External screw thread is arranged on the female thread of cylinder 11.
In the present embodiment, the female thread of screw-thread bush 2 is coaxial with external screw thread, has an advantage in that, easy to process.
In the present embodiment, the external screw thread on screw-thread bush 2 is more than female thread, and external screw thread uses fine thread, female thread
Using coarse thread, have an advantage in that, on the premise of not using other locking measure, the locking property of fine thread is preferable, separately
Outward, under the identical diameter of thread, the intensity of fine thread is higher, nipple after a long time use, the female thread of screw-thread bush 2
After damage, screw-thread bush 2 can be changed by external screw thread, and fixed base 1 need not adjust.
When needs fix equipment at aircraft cargo bay floor, need between fixed base 1 and screw-thread bush 2 to apply pretension
Power, is also required to apply pretightning force, and the former pretightning force is more than the pretightning force of the latter between fixing equipment and screw-thread bush 2,
To ensure when dismounting is by fixing equipment, do not have loosening between screw-thread bush 2 and fixed base 1.
It is understood that for the equipment bearing combined load for a long time, screw-thread bush 2 and the connection of fixed base 1
