Abstract
A kind of special purpose vehicle gas exhaust tube flange bolt is the utility model is related to, especially a kind of automobile exhaust pipe flange bolt.Screw rod is wholely set with hexagonal flange disk, described locking flute profile packing ring is enclosed on screw rod, and locking flute profile packing ring is provided with sets of holes, and set bore dia is less than hexagonal flange disk diameter, integral diameter is more than hexagonal flange disk diameter, and locking teeth is provided with the outer rim of locking flute profile packing ring.Said structure is when in use, in bolt screwing operations, locking flute profile packing ring can be extruded, when turning clockwise, locking teeth resistance is small, can smoothly it rotate, locking teeth contacts with mounting surface surface after screwing, when converse rotating force occurs, due to the overbending direction of locking teeth, effectively hexagon flange bolt can be prevented to rotate, utilize the effect of elastic pressure, and bolt is prevented to invert simultaneously, because locking teeth is bent to form a three-dimensional part, locking teeth provides elastic pressure, therefore the loosening of bolt, which can be reduced, makes bolt more fasten, antidetonation relaxation effect is fine.
Description
Technical field
A kind of special purpose vehicle gas exhaust tube flange bolt is the utility model is related to, especially a kind of automobile exhaust pipe flange spiral shell
Bolt.
Background technology
Automobile exhaust pipe plays damping noise reduction for the effect of automobile fuselage, extends the work in exhausting silencer system life-span
With.The main material of blast pipe is stainless steel.For in general automobile, because pressure is very when the waste gas of automobile leaves engine
Greatly, its caused noise may allow people to feel and go mad, and at this moment play a part of the blast pipe that main noise reduction is exactly automobile,
Its internal installation muffler, the noise of automobile greatly reduces.And its main operational principle is to make air-flow point by multichannel
Stream, these shuntings are only shown in that rubs mutually is hit so that the flow velocity of air-flow gradually reduces, and such iterative cycles are final that waste gas is led to
Cross the emission by exhaust pipe outflow of automobile so that lower noise, so as to reach the effect that routine vehicle reduces noise.At present in fixation
With common bolt when blast pipe, when fixed, because vibrations can shake, bolt is caused to loosen or come off.
Utility model content
The purpose of this utility model is, there is provided a kind of fixation, it is not easy to the automobile exhaust pipe flange bolt of loosening.
Technical scheme is used by the utility model solves its technical problem：A kind of automobile exhaust pipe flange bolt, its
It is characterised by including hexagonal flange disk, screw rod, locking flute profile packing ring, screw rod is wholely set with hexagonal flange disk, and described is locking
Flute profile packing ring is enclosed on screw rod, and locking flute profile packing ring is provided with sets of holes, and set bore dia is less than hexagonal flange disk diameter, integral diameter
More than hexagonal flange disk diameter, locking teeth is provided with the outer rim of locking flute profile packing ring.
It is of the present utility model to be further arranged to：Raised square shaped teeth, square shaped teeth are provided with the periphery of locking flute profile packing ring
Between leave gap, square shaped teeth is bent according to diagonal to screw rod direction, forms locking teeth.
It is of the present utility model to be further arranged to：The angle of described bending is 30 degree, and is bent clockwise.
Said structure when in use, in bolt screwing operations, can extrude anti-reverse ring flange, turn clockwise when
Wait, locking teeth resistance is small, can smoothly rotate, and when screwing only, locking teeth contacts with mounting surface surface, when converse rotating force occurs
Wait, due to the overbending direction of locking teeth, can effectively prevent locking flute profile packing ring from rotating, using the effect of pressure, and hinder simultaneously
Only bolt inverts, and because locking teeth is bent to form a three-dimensional part, locking teeth provides elastic pressure, therefore can fix
More firm, anti seismic efficiency is fine.
Brief description of the drawings
Fig. 1 is the structural representation of the present embodiment；
Fig. 2 is the structural representation of the locking flute profile packing ring of the present embodiment.
Embodiment
Understood with reference to figure 1, Fig. 2, a kind of automobile exhaust pipe flange bolt of the utility model, including hexagonal flange disk 1, screw rod
2nd, locking flute profile packing ring 3, screw rod 2 are wholely set with hexagonal flange disk 1, and described locking flute profile packing ring 3 is enclosed on screw rod 2, are prevented
Loose flute profile packing ring 3 is provided with sets of holes, and set bore dia is less than the diameter of hexagonal flange disk 1, and it is straight that integral diameter is more than hexagonal flange disk 1
Footpath, locking teeth 31 is provided with the outer rim of locking flute profile packing ring 3, raised square shaped teeth is provided with the periphery of locking flute profile packing ring 3,
Gap is left between square shaped teeth, square shaped teeth is bent according to diagonal to the direction of screw rod 2, forms locking teeth 31, described bending
Angle is 30 degree, and is bent clockwise.
Obviously, above-described embodiment is just for the sake of the done citing of clearly explanation, and is not the restriction to embodiment.
To those of ordinary skill in the art, other various forms of changes or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change or change thus extended out
Move still in the scope of protection of the utility model.
