Breakage, so as to can arrive to the damage of silencer.
Utility model content
To solve the above-mentioned problems, the utility model devises a kind of exhaust pipe rain-proof structure, its can avoid rainwater into
Enter into silencer, so as to avoid the damage of silencer.
What the purpose of this utility model was realized in：
The exhaust pipe rain-proof structure of the utility model, including exhaust tube body, exhaust pipe body interior are provided with several
The annular water blocking set being distributed along exhaust pipe body length direction, is vented on the inner wall of tube body to be provided with and is nested for annular water blocking
The annular groove entered, is provided with annular dash side on the madial wall of annular water blocking set, and annular dash side is to the outlet of exhaust tube body
Side extends, several annular pressing sleeves are also embedded with annular groove, and annular pressing sleeve is arranged at intervals with annular water blocking set, exhaust pipe
The port of export of body is connected with exhaust fitting, and one end of exhaust fitting towards exhaust tube body is provided with that to be inserted in annular recessed
Annular convex platform in groove, annular convex platform are threadedly coupled with annular groove, annular convex platform and the annular near annular convex platform side
The spring for holding out against annular water blocking set and annular pressing sleeve is provided between pressing sleeve, spring one end offsets with annular convex platform, another
One end with annular pressing sleeve is held to offset.
The exhaust pipe rain-proof structure of the utility model, wherein, it is provided with the first trim ring between spring and annular pressing sleeve；Pass through
The setting of first trim ring, the first trim ring can transmit the elastic force of spring, and when compressing annular pressing sleeve, enable to pair of spring
The active force of annular pressing sleeve is more balanced.
The exhaust pipe rain-proof structure of the utility model, wherein, the second trim ring is provided between spring and annular convex platform；Pass through
The setting of second trim ring, when tightening exhaust fitting, can avoid occurring showing for bite between spring end and annular convex platform
As.
The exhaust pipe rain-proof structure of the utility model, wherein, the side wall ecto-entad of annular dash side gradually tapers up.
The utility model by exhaust pipe body interior set several along exhaust pipe body length direction be distributed ring
Shape water blocking set, is provided with annular dash side on the madial wall of annular water blocking set, so, rainwater can be blocked in annular gear
The outside of waterside, can prevent rainwater along exhaust tube body inner wall flow in silencer, so as to avoid rainwater into
Enter into silencer, the damage of silencer can be avoided.
Brief description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model.
Embodiment
The utility model embodiment is described in further detail below in conjunction with the accompanying drawings.
A kind of exhaust pipe rain-proof structure, including exhaust tube body 1, exhaust tube body 1 are internally provided with several along exhaust
