To achieve the above object, the utility model provides following technical solution:
A kind of flange bolt, including nut and screw rod, the nut are fixed with ring flange close to the side of the screw rod, institute
State side of the ring flange far from the nut and its edge be provided with sealing ring, side of the ring flange far from the nut in
The side of the screw rod is integrally fixed with multiple self-locking teeth.
Through the above technical solutions, being tightened to the utility model in use, gradually screwing in screw rod to attached article
Afterwards, self-locking tooth is abutted with attached article surface, self-locking to realize, while sealing ring is pressed between ring flange and attached article,
Sealing performance is improved, rainwater is avoided to penetrate into from the gap between self-locking tooth.
Further, the ring flange coaxially offers seal groove, the sealing ring clamping far from the side of the nut
It is connected in the seal groove.
Through the above technical solutions, sealing ring is connected in seal groove, after ring flange rotation, sealing ring can be in seal groove
Rotation, avoids sealing ring from being extruded damage.
Further, the seal groove inner wall is coated with lubricant layer.
Through the above technical solutions, adding lubricant layer, reduce the resistance that sealing ring slides in seal groove.
Further, the sealing ring side wall offers annular groove at the separate nut.
Through the above technical solutions, squeezing out the gas in annular groove after sealing ring is squeezed, forming negative pressure, benefit in annular groove
With sucker principle, the sealing performance of sealing ring is improved.
Further, the annular groove bore gradually becomes smaller along its depth direction.
Through the above technical solutions, the two sides for being located at annular groove are opened to two sides respectively after sealing ring is squeezed, increase close
The contact area of seal and attachment surface.
Further, the screw rod side has been wholely set thread, and the thread is offered far from one end of the nut
Notch.
Through the above technical solutions, opening up notch on thread, the efficiency of thread tapping is improved.
Further, the cut-out section is triangular in shape.
Through the above technical solutions, the notch of triangle is easy to process and opens up.
Further, the nut and the screw rod are made into integration and are made of stainless steel.
Through the above technical solutions, the utility model is made of stainless steel, effectively enhance the corrosion-resistant of the utility model
Performance.
Compared with prior art, the utility model has the beneficial effects that
It (1), will while realizing the utility model self-locking function by the way that sealing ring and self-locking tooth are arranged on ring flange
Sealing ring is pressed between ring flange and attached article, it is ensured that the utility model also has good sealing performance;
(2) further, by opening up annular groove on sealing ring, after sealing ring is squeezed, the gas in annular groove, benefit is discharged
The sealing performance of the utility model is improved with sucker principle;
(3) further, by opening up seal groove for annular, and lubricant layer is added, reduces sealing ring in seal groove
Resistance to sliding, to avoid sealing ring extrusion damage between ring flange and attached article.

Specific embodiment
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, below with reference to embodiment and attached
The utility model is described in further detail for figure, but the embodiments of the present invention is not limited only to this.
As depicted in figs. 1 and 2, a kind of flange bolt, including nut 1 and screw rod 2, nut 1 and screw rod 2 are made into integration and adopt
It is made of stainless steel, it is ensured that the utility model has good corrosion resistance, and nut 1 is in regular hexagonal prism shape.
Nut 1 is fixed with ring flange 3 close to the side of screw rod 2, and 3 surface of ring flange is rounded, and screw rod 2 is coaxial integrally sets
It sets, there is seal groove 6 in side of the ring flange 3 far from nut 1 along its edge, and seal groove 6 is annular in shape, and coaxially sets with bill disk
It sets, clamping is connected with cricoid sealing ring 4 in seal groove 6, and sealing ring 4 is made of rubber.In use, ring flange 3 is pressed on
To in attached article, sealing ring 4 is extruded in ring flange 3 and between attached article, simultaneously as sealing ring 4 and seal groove 6 are equal
Annularly, sealing ring 4 can rotate coaxially in seal groove 6, avoid sealing ring 4 that ring flange 3 is followed to rotate, extrusion damage.Sealing
6 inner wall of slot is coated with lubricant layer 7, and lubricant layer 7 can be used solid grease and be made, coaxially turns in seal groove 6 convenient for sealing ring 4
It is dynamic.
4 side wall of sealing ring is in far from annular groove 8 is opened up at nut 1, and 8 cross section of annular groove is trapezoidal, and its bore is along its depth
Direction gradually becomes smaller.In use, sealing ring 4 is squeezed, the gas in annular groove 8 is discharged, forms negative pressure, is mentioned using the principle of sucker
High sealing performance when the utility model is used.Side of the ring flange 3 far from nut 1 is integrally fixed with more in the side of screw rod 2
A self-locking tooth 5, improves the self-locking property of nut, and 2 side of screw rod is integrally fixed with thread 10, the one end of thread 10 far from nut 1
Notch 9 is offered, 9 section of notch is triangular in shape, and then the utility model has certain self tapping ability, tap out hole.
In summary:
When the utility model is used, using the self-locking tooth 5 on ring flange 3, the utility model self-locking function is realized, meanwhile,
