Abstract
The utility model provides a kind of exhaust pipe connection structure for automobile Emissions measurement, it can solve the problems, such as the seal between connection and Full flow dilution passage when the existing assembly and disassembly of existing connection structure are cumbersome and lead to not ensure subsequently to use due to frequently assembling and disassembling.It includes connecting pipe, and one end of connecting pipe is connected with Full flow dilution passage, the connection of the other end and automobile exhaust pipe, it is characterised in that：Dock between connecting pipe and Full flow dilution passage and held tightly by anchor ear and connected.
Description
Technical field
Vehicle testing field is the utility model is related to, is specially that a kind of exhaust pipe for automobile Emissions measurement connects knot
Structure.
Background technology
Automobile is needed by a row when carrying out vehicle emission testing between the exhaust pipe and Full flow dilution passage 10 of automobile
Air pipe connection structure carries out unicom, and existing exhaust pipe connection structure includes a connecting pipe 20, one end of the connecting pipe and
Docked respectively by connecting flange 21,11 between Full flow dilution passage 10 and locking is connected by bolt 50 to prevent gas leakage, another
End is connected with exhaust pipe, sees attached drawing 1.The mobile connecting pipe of assembly and disassembly is required to before and after vehicle emission testing, and is frequently filled
Tear open and not only easily cause bolt stripped thread but also also result in the flange surface wear docked between connecting pipe and Full flow dilution passage,
Seal when can not ensure subsequently to use between connecting pipe and Full flow dilution passage, so as to influence to test effect；And lead to
Often in order to ensure being reliably connected between connecting pipe and Full flow dilution passage and seal, two flanges generally pass through eight more
Bolt 50 come lock connection, thus its assembly and disassembly are cumbersome, efficiency is low.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of exhaust pipe connection structure for automobile Emissions measurement, its
Connected when the existing assembly and disassembly of the existing connection structure of energy solution are cumbersome and lead to not ensure subsequently to use due to frequently assembling and disassembling
The problem of seal between Full flow dilution passage.
Its technical solution is that a kind of exhaust pipe connection structure for automobile Emissions measurement, it includes connecting pipe, described
One end of connecting pipe is connected with Full flow dilution passage, the other end and automobile exhaust pipe connect, it is characterised in that：The connecting tube
Dock between road and Full flow dilution passage and held tightly by anchor ear and connected.
Further, the connecting pipe and Full flow dilution passage dock end face between also pad the gold in circular ring shape is housed
Belong to gasket.
Preferably, the metal gasket is copper backing.
Further, the anchor ear includes the hoop plate of two semicirculars in shape, and hoop plate one end of described two semicirculars in shape leads to
Cross that hinge is rotatably connected, the other end is respectively equipped with wing plate, be close to and connect by bolt lock between the wing plates of two hoop plates.
The beneficial effects of the utility model are：Embraced between its connecting pipe and Full flow dilution passage using simple in structure
Hoop holds connection tightly, it is not only convenient to mount and dismount, is efficient, and using anchor ear hold tightly connection can effectively ensure that connecting pipe with it is complete
Seal between diluted stream passage；In addition, by connecting pipe and Full flow dilution passage dock end face between pad dress be in
The metal gasket of circular ring shape can be further ensured that the seal of its connection, it is ensured that test effect；In addition, two hoop plates of anchor ear
Between locking only can be realized by a bolt, be better able to improve assembly and disassembly efficiency.
