Oxygen Sensor Seat Investment Casting
The oxygen sensor is installed on the exhaust pipe of the car to detect the combustion of the engine. When installing the oxygen sensor, it is necessary to first arrange a mounting seat on the exhaust pipe, and then install the oxygen sensor on the mounting seat. When installing the mounting seat, a through hole needs to be opened on the exhaust pipe, and then the mounting seat is fixed on the through hole.

Background Technique
The oxygen sensor is installed on the exhaust pipe of the car to detect the combustion of the engine. When installing the oxygen sensor, it is necessary to first arrange a mounting seat on the exhaust pipe, and then install the oxygen sensor on the mounting seat. When installing the mounting seat, a through hole needs to be opened on the exhaust pipe, and then the mounting seat is fixed on the through hole. The mounting seat is generally fixed on the exhaust pipe by welding, and the seal between the mounting seat and the exhaust pipe The performance cannot be guaranteed so the gas in the exhaust pipe is easy to leak through the gap between the mounting base and the exhaust pipe.
Technical Realization Elements
The technical problem to be solved by the utility model is to provide an oxygen sensor installation seat, which can form better sealing performance with the exhaust pipe.
In order to solve the above technical problems, the utility model provides that the oxygen sensor mounting seat includes a mounting seat body and a sealing gasket, and the mounting seat body includes a first cylindrical portion, a first annular portion, and a second cylindrical portion and a second annular portion, the axial length of the first cylindrical portion is greater than the axial length of the second cylindrical portion, the inner peripheral wall of the first annular portion is connected to the first end surface of the first cylindrical portion, the second The outer peripheral wall of the first annular portion is connected to the first end surface of the second cylindrical portion, the second end surface of the second cylindrical portion is connected to the inner peripheral wall of the second annular portion, the sealing gasket is annular, and the sealing gasket is located on Between the first cylindrical part and the second cylindrical part, the first end surface of the sealing gasket is against the first annular part, and the second end surface of the sealing gasket is located between the second annular part and the second end surface of the first cylindrical part between.
Preferably, the first cylindrical portion, the first annular portion, the second cylindrical portion, and the second annular portion are integrally formed.
Preferably, an annular groove is provided on the outer wall of the first cylindrical portion and the inner wall of the second cylindrical portion, and the annular grooves are arc-shaped grooves.
After adopting the above structure, the utility model has the following advantages compared with the prior art:
The oxygen sensor mounting seat of the utility model is provided with a sealing gasket, so when the oxygen sensor mounting seat is installed on the exhaust pipe, the sealing gasket can be pressed tightly on the outer wall of the exhaust pipe, so that the oxygen sensor can be installed The seal between the seat and the exhaust pipe is better, which can avoid gas leakage in the exhaust pipe.
