Embodiment
Fig. 1 is refer to, the present embodiment provides a kind of reverse-filling automobile exhaust pipe device, and it mainly includes exhaust pipe 1, gear
Plate 3.Exhaust pipe 1 includes being used for the body part, the first bending part 2a and the second bending part 2b for installing baffle plate 3, exhaust pipe 1
Body, the first bending part 2a and the second bending part 2b be sequentially communicated.Need exist for explanation, the first bending part 2a and second
Bending part 2b position and annexation are not limited to shown in figure, and the first bending part 2a is vertical with the body part of blast pipe,
Second bending part 2b and the first bending part 2a end vertical, angle therebetween can be suitably adjusted according to the situation of vehicle.The
On the one hand one bending part 2a and the second bending part 2b setting can be played to a certain extent prevents ponding from entering exhaust pipe 1
Inside, on the other hand contribute to the discharge of the inside ponding of exhaust pipe 1 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 angle that the inwall for the exhaust pipe 1 that baffle plate 3 is connected with rotating part 4 is in is less than 90 degree.
Exhaust pipe 1 is provided with the first groove 6 at the inwall of rotating part 4, and the first groove 6 is located at rotating part 4 and row
Between gas port 12, the first groove 6 is used to install torque spring 7.The plate body of baffle plate 3 and the inwall of exhaust pipe 1 offer respectively
For laying the second groove 31 and the first groove extension 61 of the first branch 71 and the second branch 72, the first groove extension 61
Connected with the first groove 6.Incorporated by reference to Fig. 1 and Fig. 2, torque spring 7 includes spring body 70 and the first branch being connected with spring body 70
71st, the second branch 72, spring body 70 are located inside the first groove 6, and the first branch 71 is connected with the side wall of baffle plate 3, the second branch 72 with
The inwall connection of exhaust pipe 1.On the one hand the effect of torque spring 7 is supporting baffle 3, reach inside closing exhaust pipe 1；Separately
On the one hand it can be deformed upon in the case where waste gas is to the pressure of baffle plate 3, be easy to the discharge of waste gas.Further, since there is bullet in torque spring 7
Property potential energy, when automobile is in running order, certain angle is consistently formed between baffle plate 3 and the inwall of exhaust pipe 1.Automobile is in product
Water less position also can reach the effect of waterproof when travelling.
Further, Fig. 1 is refer to, when automobile is in off working state, position that exhaust pipe 1 contacts with baffle plate 3
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, Ke Yida
While to more preferable sealing effect, the friction of baffle plate 3 and the inwall of exhaust pipe 1 is reduced, extends the service life of blast pipe.Remove
Outside this, sealing gasket 9 is provided between stop part and baffle plate 3, the impulsive force between one side buffer stop plate 8 and baffle plate 3, is reduced
The loss of barrier plate 8 and baffle plate 3；On the other hand, sealing gasket 9 is set between barrier plate 8 and baffle plate 3, it is close between strengthening
Effect is sealed, prevents ponding from entering inside exhaust pipe 1 to a greater extent.
In summary, a kind of reverse-filling automobile exhaust pipe device provided by the invention can by waste gas provide pressure come
Controlling baffle plate and the connection inside exhaust pipe and closed state, when automobile is in off working state, due to torque spring
Support, baffle plate will be closed inside exhaust pipe, and outside ponding can not enter automobile engine by blast pipe；When automobile is in
During working condition, the air pressure that automobile exhaust gas provides forces baffle plate to rotate, now exhaust pipe internal run-through, waste gas discharge car
Outside.It has the advantages of simple in construction, cost is cheap and is easily installed.
Described above, only presently preferred embodiments of the present invention is not intended to limit the invention, patent protection model of the invention
Enclose and be defined by claims, the equivalent structure change that every specification and accompanying drawing content with the present invention is made, similarly
It should include within the scope of the present invention.
