FIG. 1 is a schematic view of the present invention;
fig. 2 is an external view of the present invention;
fig. 3 is a schematic axial view of the mounting base of the present invention.
In the figure: 1. a ceramic tube; 2. an oxygen sensitive element; 3. a sleeve; 4. a mounting seat; 5. a fixing ring; 6. a spring; 7. a movable ring; 8. a clamping block; 9. a clamping groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the utility model relates to a novel vehicle oxygen sensor, which comprises a ceramic tube 1, an oxygen sensor 2 and a mounting seat 4, wherein the oxygen sensor 2 is disposed inside the ceramic tube 1, the oxygen sensor 2 extends downward and is provided with a sleeve 3, the middle part of the ceramic tube 1 is provided with a fixing ring 5, the fixing ring 5 is fixedly connected with the ceramic tube 1, the bottom end of the fixing ring 5 is provided with a spring, the bottom end of the spring 6 is provided with a movable ring 7, the movable ring 7 is connected with the ceramic tube 1 in a sliding manner, the bottom end of the ceramic tube 1 is provided with a plurality of clamping blocks 8, the clamping blocks 8 are in a strip shape, the mounting seat 4 is mounted on an exhaust pipe, when in use, the oxygen sensor is mounted on the mounting seat 4, the mounting seat 4 is internally provided with a plurality of clamping grooves 9 matched with the clamping blocks 8, the clamping grooves 8 can be clamped into the clamping grooves 9, the clamping grooves 9 are in a special shape, the clamping blocks 8 can be inserted into the clamping grooves 9 when in mounting, rotatory ceramic tube 1 again, then pulling ceramic tube 1, can go into draw-in groove 9 with 8 card of fixture block, wholly adopt the design that does not have the screw thread, can be more convenient, swift with the dismantlement in the installation, the cooperation mode of being connected between ceramic tube 1 and the mount pad 4 is transition fit, it is inseparabler to make the connection between ceramic tube 1 and the mount pad 4, prevent the clearance, scribble the anti-sticking agent between ceramic tube 1 and the mount pad 4, when can plug up the clearance, play the dead effect of anti-sticking.
