Abstract
The utility model discloses an annular hoop bar mechanism for an exhaust system. The annular hoop mechanism for the exhaust system comprises an annular hoop and a pair of flanges. A lock nut is arranged on the annular hoop. Positioning grooves are formed in the flanges. Grooves are arranged on the inner wall of the annular hoop and tightly combined with protruded portions of the flanges after the grooves are assembled. A sealing gasket is further arranged between the two flanges, and bosses matched with the positioning grooves are arranged on the sealing gasket. According to the annular hoop mechanism, the axial direction of the installation and tightening when assemblies (between a silencer and a tail pipe, between the silencer and a silencer air inlet pipe, and between air outlet pipes) are connected is changed into the circumferential direction, so constraint conditions are reduced when the assemblies are welded and installed, connection and installation arrangement space between the assemblies and space for wrenches when the assemblies are installed are reduced, arrangement and installation of the assemblies are benefited, and work efficiency is improved when the assemblies are assembled .
Description
Technical field
The utility model relates to a kind of vent systems and connects and sealing means, is applied in the automobile exhaust system between the outlet pipe and outlet pipe, and between outlet pipe and the silencing apparatus, connecting and sealing between the assemblies such as silencing apparatus and tail pipe.
Background technique
At present, connection and sealing between each assembly of automobile exhaust system, generally the mode of employing " flange+sealing gasket+bolt " connects and seals, installation and tightening direction when connecting between each assembly of vent systems (silencing apparatus and tailpipe, silencer air inlet pipe, outlet pipe and outlet pipe) are axially.。This kind connection and sealing means need larger installation and removal space, and installation and removal are inconvenient, and inefficiency is not suitable for being applied to compact Layout.Flange is to be welded on the outlet pipe simultaneously, and planeness of flange and flange mounting hole need special welding tooling guarantee installation requirements, and welding precision requires high.
Summary of the invention
The utility model proposes a kind of vent systems hoop mechanism for the problem that proposes in the background technique, connection, sealing and mounting type between the exhaust system component have been changed, solved prior art in difficult arrangement, the problems such as the insufficient space during installation and removal, improved assembling work efficient, for the connection between the outlet pipe of vent systems different tube diameters, silencing apparatus, the tail pipe and sealing seriation, generalization and standardization provide new technological scheme, also reduced cost simultaneously.
The technical solution adopted in the utility model is: a kind of vent systems hoop mechanism, comprise hoop, hoop is provided with locking nut, it is characterized in that: also comprise a pair of flange, described hoop inwall is provided with groove, assembling rear groove and the driving fit of flange protruding part also are provided with sealing gasket between two flanges.
Preferably, described flange is provided with locating slot.
Preferably, described sealing gasket is provided with positioning boss.
The utility model beneficial effect is: the characteristic of utilizing the special-purpose hoop of vent systems can freely adjust at circumferencial direction, with each assembly of vent systems (silencing apparatus and tailpipe, silencer air inlet pipe, outlet pipe and outlet pipe) between installation when connecting and tightening direction by axially changing into along the circumferential direction, when having reduced each assembly welding and the constraint conditio of each assembly when installing.Dwindle connection between each assembly and mounting arrangements space and the spanner space when installing, be conducive to layout and the installation of each assembly, the working efficiency when having improved assembling.
