Through split type body and mounting, realize the closure of the port of body afterbody, compare in the throat technology of integral type, the body is made simply, and processing is convenient, improves machining efficiency, reduces manufacturing cost, and can improve the intensity of hush pipe afterbody for the hush pipe is not fragile, has improved hush pipe's life. The sealing sheet is connected with the port in a welding mode, so that the connection is convenient and the connection effect is good.
Furthermore, the sealing sheet is provided with a convex ring which is connected with the port. The mounting plate is provided with the convex ring, so that the mounting plate can be conveniently used for sealing the port, the connecting effect of the mounting plate and the port is improved, the mounting plate and the port are not easy to be welded, and the connecting strength of the connecting part is improved.
Further, the outer side wall of the convex ring is attached to the inner side wall of the port. The convex ring is clamped on the inner side of the port, so that the sound-deadening pipe is integrally attractive and has no abrupt appearance.
Further, the sealing sheet is provided with a second air outlet. The mounting sets up the second venthole, can be convenient for the circulation of the intraductal gas of amortization.
Further, the body is equipped with the fixed slot, and the fixed slot is followed the outer wall evenly distributed of body. The body sets up the fixed slot, when making body and muffler welding, the solder can imbed the fixed slot after melting, improves the welding effect of body and muffler, improves joint strength.
Furthermore, the air inlet is provided with a guide surface, and the radius of the cross section of the guide surface from one end close to the air inlet to one end far away from the air inlet is gradually reduced. The air inlet sets up the spigot surface, can make things convenient for air inlet end cap setting in the air inlet, the quick installation of the air inlet end cap of being convenient for.
Further, first venthole can improve noise cancelling effect along the outer wall evenly distributed of body.
Due to the adoption of the technical scheme, the utility model has the following beneficial effects:
according to the utility model, through the split type silencing pipe, the processing cost can be effectively reduced, the processing efficiency is improved, the processing is more convenient, the strength of the tail part of the silencing pipe can be improved, and the tail part of the silencing pipe is not easy to damage.
