Abstract
A kind of special purpose vehicle gas exhaust tube flange straight burr press mounting bolt is the utility model is related to, especially a kind of automobile exhaust pipe flange straight burr press mounting bolt.The head of screw rod is provided with the compressive plane of a taper, a sunken groove is provided with the afterbody of screw rod, fall into the diameter that groove size is less than screw rod, the afterbody of screw rod is wholely set with straight burr fixed station, described straight burr fixed station is circle, in circumference side, the groove being spaced apart is provided with, groove is towards screw rod axial direction.Said structure is when installing and using, mounting surface is squeezed first with compressive plane, and vertical compression is when enter mounting surface, the material of mounting surface is absorbed in sunken groove and second and falls into groove respectively, and the second compressive plane can reduce resistance, and makes pressure hole more smooth, the groove of straight burr fixed station is absorbed in mounting surface, it is easy to operate when preventing axial-rotation, therefore install, and fastness is very high.
Description
Technical field
It the utility model is related to a kind of special purpose vehicle gas exhaust tube flange straight burr press mounting bolt, especially a kind of automobile exhaust pipe
Flange straight burr press mounting 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.Applying at present
Fixing bolt on automobile exhaust pipe, typically weld or rivet, but weld and riveting also often go wrong,
Mode that is cumbersome and unstable, and riveting is welded, due to not positioning, it is difficult to ensure that pressure during riveting
Uniformity, and the phenomenon of rotation occurs in riveting process, then just leverage the fastness and stability of riveting.
Utility model content
The purpose of this utility model is, there is provided a kind of automobile exhaust pipe flange straight burr pressure easy for installation, fixation
Fill bolt.
Technical scheme is used by the utility model solves its technical problem：A kind of automobile exhaust pipe flange straight burr press fitting
Bolt, including screw rod, nut, it is characterised in that also including straight burr fixed station, the head of screw rod is provided with the compressive plane of a taper,
A sunken groove is provided with the afterbody of screw rod, falls into the diameter that groove size is less than screw rod, afterbody and the straight burr fixed station of screw rod are integrally set
Put, described straight burr fixed station is circle, in circumference side, is provided with the groove being spaced apart, and groove is towards screw rod axial direction side
To, straight burr fixed station is wholely set with nut, and the diameter of straight burr fixed station is more than the diameter of screw rod, and less than the diameter of nut.
It is of the present utility model to be further arranged to：The connecting portion arc surface of described screw rod and straight burr fixed station, formed
Second order compressive plane.
It is of the present utility model to be further arranged to：Be provided with depression in the connecting portion of straight burr fixed station and nut second falls into
Groove.
Said structure squeezes mounting surface when installing and using, first with compressive plane, and vertical compression enter mounting surface when
Wait, the material of mounting surface is absorbed in sunken groove and second and falls into groove respectively, and the second compressive plane can reduce resistance, and makes pressure hole more flat
Whole, the groove of straight burr fixed station is absorbed in mounting surface, easy to operate when preventing axial-rotation, therefore install, and fastness
It is very high.
Brief description of the drawings
Fig. 1 is the structural representation of the present embodiment.
Embodiment
Understood with reference to figure 1, a kind of automobile exhaust pipe flange straight burr press mounting bolt of the utility model, including screw rod 1, nut 2,
Also include straight burr fixed station 3, the head of screw rod 1 is provided with the compressive plane 11 of a taper, a sunken groove is provided with the afterbody of screw rod 1
12, the diameter that the size of groove 12 is less than screw rod 1 is fallen into, afterbody and the straight burr fixed station 3 of screw rod 1 are wholely set, and described straight burr is fixed
Platform 3 is circle, in circumference side, is provided with the groove 31 being spaced apart, groove 31 is fixed towards the axial direction of screw rod 1, straight burr
Platform 3 is wholely set with nut 2, and the diameter of straight burr fixed station 3 is more than the diameter of screw rod 1, and less than the diameter of nut 2, it is described
The connecting portion arc surface of screw rod 1 and straight burr fixed station 3, second order compressive plane 31 is formed, in the company of straight burr fixed station 3 and nut 2
Socket part is provided with the second sunken groove 32 of depression.
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.
