A kind of anti-water ingress device for automobile exhaust pipe

Abstract

The invention discloses a water resisting device for a vehicle exhausting pipe. A horizontal moving pipe is inserted in a horizontal casing pipe. The diameter of the inner ring of an annular baffle isgreater than the diameter of the outer ring of the horizontal moving pipe. An annular rubber sealing plate is fixedly pasted to the right lateral surface of the annular limiting plate. The annular rubber sealing plate is located in an annular clamping groove of the inner wall of the right opening of the horizontal casing pipe. The right end of the horizontal moving pipe communicates with a longitudinal pipe fitting. The right opening of the horizontal moving pipe is fixedly connected with the outer wall of the longitudinal pipe fitting and is close to the bottom end. A u-shaped pipe is inserted in the upper opening of the longitudinal pipe fitting. Inverting preventing u-shaped design is adopted for the u-shaped pipe, and therefore rainwater does not fall inside the u-shaped pipe in rainydays. The u-shaped pipe prevents water flow from entering a vehicle through the u-shaped pipe, the longitudinal pipe fitting and the horizontal moving pipe when the water level is high during heavy rains. Height of the u-shaped pipe can be adjusted based on the water level, and therefore application is convenient.

Description

technical field [0001] The invention relates to the technical field of a water ingress prevention device for an automobile exhaust pipe, in particular to a water ingress prevention device for an automobile exhaust pipe. Background technique [0002] The exhaust pipe is a device for reducing vibration and noise, facilitating installation and prolonging the life of the exhaust muffler system. It is installed between the engine exhaust manifold and the muffler, so that the entire exhaust system is flexibly connected. Exhaust pipes are mainly used for light vehicles, mini-cars and passenger cars, motorcycles. The structure of the exhaust pipe is a double-layer corrugated pipe covered with a steel mesh sleeve, and the straight edge sections at both ends are covered with snap rings, in order to make the noise reduction effect better. , the bellows can be equipped with expansion joints or mesh sleeves, but it still has the following disadvantages in actual use: [0003] Because th...

AI Technical Summary

Problems solved by technology

[0003] Since the exhaust pipe of the automobile is connected with the outside world, when the water level on the road surface is high in rainy weather, the rainwater will directly enter the interior of the car body from the exhaust pipe, thereby reducing the service life of the automobile.
