Abstract
The application belongs to securing member design field, in particular to a kind of self-locking countersunk nut, it include: nut body, there is cyclic convex edge nut body axial direction one end end is circumferentially arranged, and radially opened up on the end face of the cyclic convex edge fluted, there is the necking that is recessed to axis direction in the inner wall of the nut body, the self-locking countersunk nut of the application can guarantee concordant with mounting surface, and have the function of it is self-locking, also have versatility.
Description
Technical field
The application belongs to securing member design field, in particular to a kind of self-locking countersunk nut.
Background technique
It needs to keep the smooth of shape on the airfoil of aircraft, but has the fastener on individual sites through upper bottom wing
Face causes nut exposed outside, impacts to flight.
Thus, it is desirable to have a kind of technical solution overcomes or at least mitigates at least one drawbacks described above of the prior art.
Utility model content
There is provided a kind of self-locking countersunk nuts for the purpose of the application, to solve the problems, such as the prominent shape of nut, and energy
Enough there is versatility.
The technical solution of the application is:
A kind of self-locking countersunk nut, comprising:
Nut body has cyclic convex edge nut body axial direction one end end is circumferentially arranged, and in the ring-type
It radially opens up fluted on the end face of convex edge, there is the necking that is recessed to axis direction in the inner wall of the nut body.
Optionally, external screw thread is offered in the outside wall surface of the self-locking countersunk nut.
Optionally, the groove is linear type groove.
Optionally, the necking is annular in shape.
Optionally, the axial medium position of the nut body is arranged in the necking.
At least there are following advantageous effects in application:
The self-locking countersunk nut of the application can guarantee it is concordant with mounting surface, and have the function of it is self-locking, also have it is general
Property.
Detailed description of the invention
Fig. 1 is the configuration diagram of the self-locking countersunk nut of the application；
Fig. 2 is the sectional view of the self-locking countersunk nut of the application；
Fig. 3 is the installation cut away view of the self-locking countersunk nut of the application in embodiment.
Specific embodiment
To keep the purposes, technical schemes and advantages of the application implementation clearer, below in conjunction in the embodiment of the present application
Attached drawing, technical solutions in the embodiments of the present application is further described in more detail.In the accompanying drawings, identical from beginning to end or class
As label indicate same or similar element or element with the same or similar functions.Described embodiment is the application
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
In explanation the application, and it should not be understood as the limitation to the application.Based on the embodiment in the application, ordinary skill people
Member's every other embodiment obtained without creative efforts, shall fall in the protection scope of this application.Under
Face is described in detail embodiments herein in conjunction with attached drawing.
In the description of the present application, 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 the application and simplifies 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 application
The limitation of range.
1 to Fig. 3 the application is described in further details with reference to the accompanying drawing.
As shown in Figures 1 and 2, the self-locking countersunk nut of the application, is reequiped by nut body, has circumferential setting on its top
Cyclic convex edge, convex edge have transition inclined-plane, be also provided with groove in the end on convex edge top, it is to be appreciated that: groove
Linear type or cross can be opened up into, in the present embodiment, using linear type groove, can be pacified using existing tool
Dress, the top end of the self-locking countersunk nut of the application can also be arranged to close, when being closing end, open up ten
Font groove can equally be installed with existing tool, when not being closing end, can apply matched cross work
Tool is installed, and the self-locking countersunk nut of the application is equipped with internal screw thread, as shown in Figure 2, in the inner wall of self-locking countersunk nut
The upper also oriented necking being recessed to axis direction.
In the present embodiment, such as Fig. 3, the self-locking countersunk nut of the application is installed, there is upper interlayer and lower folder in Fig. 3
Layer, it is to be appreciated that: the mounting hole of upper interlayer is bigger than the installation bore dia of lower interlayer, and the mounting hole installation of upper interlayer is self-locking heavy
Head nut, and connect with matched bolt thread, self-locking countersunk nut can be entirely packed into the mounting hole of upper interlayer, installation
Effect is as shown in figure 3, mounted self-locking countersunk nut is concordant with the upper surface of upper interlayer, without part outstanding, and Fig. 2
In arrow direction refer to self-locking countersunk nut necking position, circlewise structure can be set in necking, can also be arranged to
For the structure of segmented, mutual pressure will receive when connecting with bolt thread, between necking and bolt, realize self-locking function
Energy.
It is to be understood that the outside wall surface of self-locking countersunk nut includes externally threaded with without externally threaded, there is external screw thread
Self-locking countersunk nut be threadedly coupled with connector, and connect with bolt thread, ensure that self-locking countersunk nut and connector it
Between stabilization, can be realized can be along the locking for the connector that bolt axial ends moves, and what is applied in the present embodiment is without outer
The self-locking countersunk nut of screw thread realizes that one kind is fastenedly connected and can be self-locking.
The above, the only specific embodiment of the application, but the protection scope of the application is not limited thereto, it is any
Within the technical scope of the present application, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
Cover within the scope of protection of this application.Therefore, the protection scope of the application should be with the scope of protection of the claims
It is quasi-.
