For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0021] Please refer to Figures 1-4 The present application provides a technical solution: a high-sealing automobile engine exhaust device, comprising:

[0022] The engine exhaust pipe 100 is provided with a split type exhaust filter assembly, and the exhaust filter assembly comprises an exhaust pipe filter 200, a connecting pipe A 201 and a connecting pipe B 300.

[0023] The engine exhaust pipe 100 has two sections, and the two sections of the engine exhaust pipe 100 have a spacing, the exhaust pipe filter 200 is located between the two sections of the engine exhaust pipe 100, the number of the connecting pipe A 201 is two, the two connecting pipes A 201 are respectively located at both ends of the exhaust pipe filter 200, the connecting pipe A 201 is welded and fixed with the exhaust pipe filter 200, and each connecting pipe A 201 has a connecting pipe B 300 on the side surface, and the connecting pipe A 201 and the connecting pipe B 300 are buckled and wrapped around the end of the engine exhaust pipe 100.

[0024] Further, the outer side of the adapter pipe A201 has two integrally fixed mounting pieces A203, and a plurality of through holes are formed on each mounting piece A203. The outer side of the adapter pipe B300 has two integrally fixed mounting pieces B302, and a plurality of through holes are formed on each mounting piece B302. The through holes on the mounting piece B302 correspond to the through holes on the mounting piece A203.

[0025] Further, the mounting piece A203 is attached to the mounting piece B302, and a plurality of screws and nuts are used to limit and fix the connection between the mounting piece A203 and the mounting piece B302. After the mounting piece A203 is attached to the mounting piece B302, the screws and nuts are tightened to limit and fix the connection, so that the adapter pipe B300 and the adapter pipe A201 are fixed to form a whole.

[0026] Further, one end of the adapter pipe A201 is provided with a clamping groove A202, and one end of the adapter pipe B300 is provided with a clamping groove B301. The ends of the clamping groove A202 and the clamping groove B301 are aligned. The outer side of the engine exhaust pipe 100 is integrally fixed with a limiting ring A101, which is embedded in the inside of the clamping groove A202 and the clamping groove B301. One end of the engine exhaust pipe 100 is integrally fixed with a limiting ring B102. The limiting ring B102 and the limiting ring A101 are separated by a spring 400. One end of the spring 400 abuts against the limiting ring B102, and the other end of the spring 400 abuts against the adapter pipe A201 and the adapter pipe B300.
