Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Referring to Fig. 1, exhaust pipe structure of the present utility model, using on the engine, installed in the cylinder head 1 of engine
On, for realizing that the acceleration of engine is radiated.If exhaust pipe structure includes flange 2, blast pipe 3, bolt stem 4, pad 5.
The one end of flange 2 is mounting surface 21, and its opposite other end is locating surface 22.The exhaust outlet of the cylinder head 1 of engine leads to
Cross flange 2 and connect blast pipe 3, the mounting surface 21 of flange 2 is attached on end face of the cylinder head 1 with exhaust outlet.If flange 2 by
Bolt stem 4 is fixed in cylinder head 1.
Incorporated by reference to Fig. 2, pad 5 is attached on end face of the cylinder head 1 with exhaust outlet, and the exhaust outlet is passed through pad 5
Through hole just communicated via flange 2 with blast pipe 3, mounting surface 21 by pad 5 support cylinder head 1 with exhaust outlet end face
On.
At least one breach 7 of edge of mounting surface 21, bolt 4 passes through from the locating surface 22 of flange 2, and penetrates flange
The breach 7 at 2 edge of mounting surface 21, then stretched into after penetrating pad 5 in the end face of the exhaust outlet of cylinder head 1.
Pass through design method of the present utility model so that the mounting surface 21 of flange 2 has the end face of exhaust outlet with cylinder head 1
Between contact surface reduced concept feasible be present, solve the problem of prior art.The utility model is simple in construction, but effect
Huge, the heat dissipation capacity of unit interval blast pipe 3 greatly improves, reduce bolt 4 loosening risk, reduce intake air temperature, improve into
Tolerance, burning is abundant, reduces discharge, therefore cost performance is very high.Because structure improves the huge effect brought so that product is in city
Field has more dominance on promoting, and turns into a big sale bright spot of product, whether there is this architectural feature, exist in selling price
One huge class, while also increase product money kind.
Mounting surface 21 supports pad 5 on the end face that cylinder head 1 has exhaust outlet, therefore, on the one hand, although in flange
The edge of 2 mounting surface 21 breach 7, but breach 7 do not have an impact original locating effect of bolt；On the other hand,
Pad 5 is supported to the side on the end face that cylinder head 1 has exhaust outlet by setting up pad 5, and using the mounting surface 21 of flange 2
Formula, show no sign of influenceing the sealing between original blast pipe 3 and the exhaust outlet of cylinder head 1.
Therefore, on the premise of the utility model can seal ensureing blast pipe 3, the contact area with cylinder head 1 is reduced, is increased
Add blast pipe 3 and the area of dissipation of cylinder head 1, the heat dissipation capacity of unit interval is so greatly improved, so as to overcome radiating effect
The shortcomings of poor, bolt 4 easily loosens, intake air temperature is high, and discharge increases.
The quantity of breach 7 can be one, and part bolt 4 uses design of the present utility model, can also be with bolt 4
Quantity it is identical, the corresponding bolt 4 of each breach 7.When the quantity of breach 7 is multiple, mounting surface 21 is evenly distributed on as far as possible
Edge, to keep certain degree of balance.When the quantity of breach 7 is one, breach 7 is as far as possible using the center line of mounting surface 21 in
Thimble is wound on the edge of mounting surface 21, such as breach 7 in a ring.
In summary, the utility model structure design is simple, and on the premise of ensureing to seal, reduction connects with cylinder head 1
Contacting surface is accumulated, and increases blast pipe 3 and the area of dissipation of cylinder head 1, and unit interval blast pipe heat dissipation capacity greatly improves, and reduces bolt
4 risks loosened, reduce intake air temperature, improve air inflow, and burning is abundant, reduces discharge.
In order to be greatly decreased the mounting surface of flange and cylinder head has contact surface between the end face of exhaust outlet, in other realities
Apply in example, if as shown in figure 3, the exhaust pipe structure may also include some elastic components 6 corresponding with bolt stem 4.Each elasticity
Part 6 is enclosed on corresponding bolt 4, and compressive deformation is between breach 7 and pad 5.So, even if the mounting surface and cylinder of flange
Contact surface between end face of the lid with exhaust outlet is greatly decreased, and also can guarantee that the sealing of whole exhaust pipe structure.
Meanwhile by the way that the both ends of elastic component 6 are separately fixed on end face of the cylinder head 1 with exhaust outlet and in breach,
So as to further reduce bolt 4 because of the defects of bringing of expanding with heat and contract with cold.Such as, one end of each elastic component 6 is fixed on gas through pad 5
Cylinder cap 1 has on the end face of exhaust outlet, and the opposite other end of each elastic component 6 is fixed in breach 7.Elastic component 6 can be spring
Or rubber column.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
