Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
In the description of the present invention, it should be noted that term " on ", "lower", "inner", "outside" " front end ", " after
The orientation or positional relationship of the instructions such as end ", " both ends ", " one end ", " other end " is that orientation based on the figure or position are closed
System, is merely for convenience of describing the present invention and simplifying the description, rather than the device or element of indication or suggestion meaning are necessary
It with specific orientation, is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition,
Term " first ", " second " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " being provided with ", " connection " etc., shall be understood in a broad sense, such as " connection ", may be a fixed connection, be also possible to detachably connect
It connects, or is integrally connected；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, intermediate matchmaker can also be passed through
Jie is indirectly connected, and can be the connection inside two elements.It for the ordinary skill in the art, can be with concrete condition
Understand the concrete meaning of above-mentioned term in the present invention.
As shown in Figs. 1-5, a kind of aircraft housing collar nut, including link block 1, the top of link block 1 are embedded installation
There is the first connecting pin 2, the side of link block 1, which is embedded, is equipped with second connection end 3, and the top of link block 1 is arranged to be connect with first
The outside at end 2 is equipped with the first gasket 4, and the first gasket 4 is fixedly connected by lacing wire 7 with link block 1, the side set of link block 1
If the outside with second connection end 3 is equipped with the second gasket 5, the first connecting pin 2 is connected to the inside of second connection end 3, and first
Flow guide bar 6 is equipped with inside the deflection angle of 3 connectivity part of connecting pin 2 and second connection end；
First connecting pin 2 and the outer surface of second connection end 3 offer external screw thread, and the first connecting pin 2 and the second connection
The diameter at end 3 is equivalent, and external screw thread can play the external internal screw thread of cooperation and be attached fixed effect；Second gasket 5 with connect
It is equally fixedly connected by lacing wire 7 between block 1,7 quantity of lacing wire between the first gasket 4 and link block 1 is four；Flow guide bar 6,
First connecting pin 2 is that integral type connects with the connection type of second connection end 3；The shape of link block 1 is square, and link block
1 outer surface is coated with rust-proof coating, and rust-proof coating can play the role of slowing down speed of getting rusty；It is set between lacing wire 7 and link block 1
