Embodiment
Fig. 1 is refer to, the present embodiment provides a kind of water-proof exhaust pipe, and it mainly includes exhaust pipe 1, baffle plate 3.Blast pipe
Body 1 includes being used for installing the body part, the first bending part 2a and the second bending part 2b of baffle plate 3, the body of exhaust pipe 1, the
One bending part 2a and the second bending part 2b are sequentially communicated.Need exist for explanation, the first bending part 2a and the second bending part 2b
Position and annexation be not limited to shown in figure, the first bending part 2a is vertical with the body part of blast pipe, the second bending
Portion 2b and the first bending part 2a end vertical, angle therebetween can be suitably adjusted according to the situation of vehicle.First bending part
On the one hand 2a and the second bending part 2b setting can be played to a certain extent prevents ponding from entering inside exhaust pipe 1, separately
On the one hand the discharge of the inside ponding of exhaust pipe 1 is contributed to after ponding disperses.
The both ends of exhaust pipe 1, which are respectively equipped with, connects gas port 11 and exhaust outlet 12, and exhaust outlet 12 is located at the second bending part 2b's
End.Exhaust pipe 1 is divided into inner and outer wall, and the cross section of the inwall of exhaust pipe 1 is square or rectangular shape, is easy to keep off
The installation of plate 3 and the effect for reaching closing.The sidepiece of the side of baffle plate 3 is rotatably connected with the inwall of exhaust pipe 1.Specifically, keep off
The sidepiece of plate 3 is provided with rotating part 4, and rotating part 4 offers the through hole of insertion, exhaust pipe 1 with 4 corresponding inwall of rotating part
The fixed part (not shown) of setting, rotary shaft 5 are rotated the inwall of baffle plate 3 and exhaust pipe 1 by fixed part and through hole
Connection.In addition, for the rotating part 4 of baffle plate 3 close to gas port 11 is connect, sidepiece of the baffle plate 3 away from rotating part 4 is remote to connect gas port 11,
Herein also it is understood that the inwall for the exhaust pipe 1 that baffle plate 3 is connected with rotating part 4 be in angle be less than 90 degree, need exist for
Illustrate, be here in order to which baffle plate 3 acts on the lower row for being easier rotation, being easy to gas under pneumatic pressure in the angle less than 90 degree
Go out.
It refer to Fig. 2, the end face relative with the bottom interior wall of exhaust pipe 1 of baffle plate 3 and the bottom interior wall of exhaust pipe 1 pass through the
One spring 6 connects, and for the first spring 6 at least provided with one, the other end of baffle plate 3 and the top inner wall of exhaust pipe 1 pass through the
Two springs 7 connect, and the first spring 6 and second spring 7 are provided with least one.Herein it should be noted that the He of the first spring 6
Second spring 7 and 3 perpendicular relation of baffle plate are preferable scheme.In addition, the quantity and specification of the first spring 6 and second spring 7
Can be inconsistent.
When automobile is in running order, waste gas, which enters, connects gas port 11, and baffle plate 3 is under the pressure of waste gas to the bottom of exhaust pipe 1
The inwall in portion is rotated, and now the first spring 6 is compressed in the presence of baffle plate 3, and second spring 7 is stretched, inside exhaust pipe 1
Insertion, waste gas are emitted into the external world by exhaust outlet 12；When automobile is in off working state, the first spring 6 and second spring 7 are distinguished
Elastic potential energy when depositing elastic potential energy when compressed and being stretched, the first spring 6 and the homing of second spring 7, now
Baffle plate 3 closes exhaust pipe 1.
Further, the outer cover of the spring body part of the first spring 6 and second spring 7 is provided with sleeve 10.Accordingly,
Sleeve 10a is arranged to outside first spring 6, sleeve 10b is arranged to outside second spring 7, sleeve 10a length is less than the first bullet
The length of spring 6, sleeve 10b length are less than the length of second spring 7.Sleeve 10a setting on the one hand can reduce waste gas and
Corrosion of the water to the first spring 6, baffle plate 3 on the other hand can be made certain angle to be all the time present with the bottom wall inside exhaust pipe 1,
Prevent ponding from entering inside blast pipe；Sleeve 10b is mainly used for reduction waste gas to be caused to corrode to second spring 7, extends exhaust
The service life of pipe.
Further, when automobile is in off working state, the position that exhaust pipe 1 contacts with baffle plate 3 is provided with stop part,
Barrier plate 8 and the inwall of exhaust pipe 1 are formed in one structure.Baffle plate 3 cooperates with stop part, can reach more preferable closing
While effect, the friction of baffle plate 3 and the inwall of exhaust pipe 1 is reduced, extends the service life of blast pipe.In addition, stop
Sealing gasket 9 is provided between portion and baffle plate 3, the impulsive force between the one side available buffer barrier plate 8 of sealing gasket 9 and baffle plate 3, reduces resistance
The loss of baffle plate 8 and baffle plate 3；On the other hand, sealing gasket 9, the sealing between strengthening are set between barrier plate 8 and baffle plate 3
Effect, prevent ponding from entering inside exhaust pipe 1 to a greater extent.
Further, recess 91 is offered with the opening position that baffle plate 3 contacts incorporated by reference to Fig. 1 and Fig. 3, sealing gasket 9.Baffle plate 3
It is engaged with the recess 91 of sealing gasket 9, can reach better seal effect, and then improve the waterproof ability of blast pipe.
In summary, a kind of water-proof exhaust pipe provided by the invention can by waste gas provide pressure come controlling baffle plate with
Connection and closed state inside exhaust pipe, when automobile is in off working state, baffle plate is due to the support force of the first spring
Under the pulling force effect of second spring, baffle plate will be closed inside exhaust pipe, and outside ponding can not enter vapour by blast pipe
Car engine；When automobile is in running order, the air pressure that automobile exhaust gas provides forces the spring of baffle effect first and the second bullet
Spring, flapper, now exhaust pipe internal run-through, waste gas are discharged outside car.It has that simple in construction, cost is cheap and is easy to
The advantages of installation.
Described above, only presently preferred embodiments of the present invention is not intended to limit the invention, patent protection model of the invention
