Bolts and nuts are widely used in every field as a kind of conventional fastener.When they are applied to warp
When often on the mobile object with vibrations, use for a long time, nut is easy to from bolt split away off due to loosening, causes
Product quality problem or economic loss.Especially railway nut, more should be noted the loose or dislocation problem of nut, therefore
Need a kind of jam nut of the locking anti-dropout of railway.
Utility model content
The purpose of this utility model is and a kind of railway abnormal shape proposed in order to solve shortcoming present in prior art
The locking Anti-falling-off nut of tooth.
To achieve these goals, the utility model employs following technical scheme：
A kind of locking Anti-falling-off nut of railway heterodont, including nut body are designed, nut body includes the first sub- spiral shell
Female and the second sub- nut, the first sub- nut is by being threadably mounted on bolt, and the first sub- nut is away from bolt head
Side be provided with flange, the approximate circular tube shaped of the flange, and the flange thickness from one end close to the first sub- nut to
Outside is gradually successively decreased, and multiple breaches are circumferentially provided with along the flange outer wall, and breach be arranged in parallel with the first sub- nut axis, institute
Stating the inner surface setting of flange has multiple locking teeths, and the end of the locking teeth is stuck in the screw thread of bolt；The second sub- spiral shell
Mother is provided with the recessed of cylinder by being threadably mounted at bolt end, the second sub- nut close to the side of the first sub- nut
Groove, the flange is stuck in groove.
It is preferred that, the first sub- nut abuts spring washer close to the side of bolt head, and the spring washer abuts plain cushion.
It is preferred that, along the first sub- nut axis and away from the direction of the first sub- nut, the locking teeth is gradually
Become big.
It is preferred that, the internal diameter of the groove is more than the minimum outer diameter of flange, and the internal diameter of the groove is less than the maximum of flange
External diameter.
It is preferred that, the first sub- nut is hex nut.
The utility model proposes a kind of railway locking Anti-falling-off nut of heterodont, beneficial effect is：Nut side
Provided with a flange, locking teeth in flange is stuck can to play a part of braking in screw thread, and flange itself is up-small and down-big
Structure, is decomposed into downward thrust so that nut overall structure is more firm, and the utility model makes by a thrust part for level
With conveniently, sound construction effectively realizes locking anticreep.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.
Reference picture 1-2, a kind of railway locking Anti-falling-off nut of heterodont, including the first sub- nut 3, the first sub- nut 3
For hex nut, the first sub- nut 3 is by being threadably mounted on bolt 7, and the first sub- nut 3 is tight close to the side on the head of bolt 7
By spring washer 2, spring washer 2 abuts plain cushion 1, and plain cushion 1 is pressed on the piece surface for needing to fasten, and spring washer 2 is by active force to the first sub- spiral shell
Mother 3 transmits.
First side of the sub- nut 3 away from the head of bolt 7 is provided with flange 4, the approximate circular tube shaped of flange 4, the thickness of flange 4
Gradually successively decrease laterally from one end close to the first sub- nut 3, multiple breaches 9, breach are circumferentially provided with along the outer wall of flange 4
9 and first the sub- diameter parallel of nut 3 set, the first sub- nut 3 is received in the press-in groove 5 of pressure drop flange 4 that spring washer 2 is transmitted,
The limitation that flange 4 receives the size of groove 5 is extruded and must be deformed inward.
The inner surface setting of flange 4 has multiple locking teeths 8, and locking teeth 8 is with the increase with the first sub- air line distance of nut 3
Become larger, the end of locking teeth 8 is stuck in the screw thread of bolt 7, flange 4, which is deformed inward, is pressed on locking teeth 8 in screw thread, rise
To the effect of braking, when flange 4 is not deformed, locking teeth 8 is not contacted with screw thread, the installation of the first sub- nut 3 will not be hindered, because convex
After edge 4 is deformed, its Leading Edge Deformation is larger, therefore the locking teeth 8 close to end is larger so that can each serve as and not hinder before and after deformation
Assembling and the effect of locking.
The second sub- nut 6 by being threadably mounted at the end of bolt 7, the second sub- nut 6 close to the first sub- nut 3 one
Side is provided with the groove 5 of cylinder, and flange 4 is stuck in groove 5, and the internal diameter of groove 5 is more than the minimum outer diameter of flange 4, groove 5
Internal diameter is less than the maximum outside diameter of flange 4, and the limit flange 4 that groove 5 plays a part of moves and deforms it, after locking, spring washer
The cross force of transmission a, part is decomposed into the power of press flange 4 by groove 5, so that nut is more firm.
Workflow：When needing to install, plain cushion 1 and spring washer 2 are put on bolt, the first sub- nut 3 is screwed into bolt pressure
Tight plain cushion 1, the second sub- nut 6 is screwed into bolt presses flange 4 makes locking teeth 8 stuck in screw thread.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
