Description

Technical Field

[0001] This utility model relates to the field of oxygen sensor installation technology, and specifically to an oxygen sensor installation structure. Background Technology

[0002] The oxygen sensor is a key feedback sensor in the electronic fuel injection engine control system. It is a crucial component for controlling vehicle exhaust emissions, reducing vehicle pollution, and improving the quality of fuel combustion in vehicle engines. The oxygen sensor is usually installed on the engine exhaust pipe.

[0003] Currently, oxygen sensors are connected to the engine exhaust pipe of automobiles via threads. Both disassembly and installation require tools, making the installation and removal of oxygen sensors inconvenient. Therefore, there is an urgent need to design an oxygen sensor mounting structure to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an oxygen sensor mounting structure to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An oxygen sensor mounting structure includes a car exhaust pipe. A boss is integrally formed on the top outer wall of the exhaust pipe. An insertion hole is formed on the top outer wall of the boss. An oxygen sensor body is inserted into the insertion hole. A conical ring is fixed to the outer wall of the oxygen sensor body. A claw is fixed to the top outer wall of the boss, and the claw engages with the conical ring. A collar is sleeved on the outer wall of the oxygen sensor body. A handle is fixed to the outer wall of the collar. A conical surface is provided at the bottom of the collar. An inclined surface is provided on the side wall of the claw near the collar.

[0007] Furthermore, a second collar is sleeved on the outside of the boss, the claw is located inside the second collar, and a second handle is fixed to the outer wall of the second collar.

[0008] Furthermore, an elastic pad is provided between the conical ring and the boss, which is sleeved on the outside of the oxygen sensor body. A spring is sleeved on the outside of the first collar, and the spring is located between the second collar and the first handle.

[0009] Furthermore, a detection end is provided at the bottom of the oxygen sensor body, and the detection end extends into the interior of the vehicle exhaust pipe.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-2As shown in the figure, an oxygen sensor mounting structure provided by this utility model includes a car exhaust pipe 1. The top outer wall of the car exhaust pipe 1 is integrally formed with a boss 2. The top outer wall of the boss 2 has an insertion hole 11. An oxygen sensor body 4 is inserted into the insertion hole 11. A conical ring 5 is fixed to the outer wall of the oxygen sensor body 4. A claw 3 is fixed to the top outer wall of the boss 2. The claw 3 is engaged with the conical ring 5. A collar 6 is sleeved on the outer wall of the oxygen sensor body 4. A handle 13 is fixed to the outer wall of the collar 6. A conical surface 16 is provided at the bottom of the collar 6. An inclined surface 17 is provided on the side wall of the claw 3 near the collar 6.

[0020] Specifically, in this embodiment, the vehicle exhaust pipe 1 is included. The top outer wall of the vehicle exhaust pipe 1 is integrally formed with a boss 2. The boss 2 is circular. The top outer wall of the boss 2 has an insertion hole 11. An oxygen sensor body 4 is inserted into the insertion hole 11. The oxygen sensor body 4 is a sensor used in the prior art to detect the oxygen concentration in engine exhaust gas. A conical ring 5 is fixed to the outer wall of the oxygen sensor body 4. The bottom side of the conical ring 5 is conical. A claw 3 is fixed to the top outer wall of the boss 2. The claw 3 engages with the conical ring 5. The oxygen sensor body 4 is fixed by engaging the claw 3 with the conical ring 5. A collar 6 is sleeved on the outer wall of the oxygen sensor body 4. A handle 13 is fixed to the outer wall of the collar 6. A conical surface 16 is provided at the bottom of the collar 6. An inclined surface 17 is provided on the side wall of the claw 3 near the collar 6. When the collar 6 is pressed down, the claw 3 can be squeezed by the conical surface 16, thereby causing the claw 3 to disengage from the conical ring 5.

[0021] The present invention provides an oxygen sensor mounting structure in which the claw 3 engages with the conical ring 5 on the outside of the oxygen sensor body 4, allowing the oxygen sensor body 4 to be installed by simply plugging it in. During disassembly, the collar 6 presses against the claw 3, causing the claw 3 to disengage from the conical ring 5, thereby achieving a more convenient installation and disassembly of the oxygen sensor.

[0022] In another embodiment of this utility model, a collar 2 18 is sleeved on the outside of the boss 2, and the claw 3 is located inside the collar 2 18. By sleeved on the outside of the boss 2, the collar 2 18 can limit the claw 3, preventing the claw 3 from disengaging from the conical ring 5 due to vibration, thereby making the installation of the oxygen sensor body 4 more reliable. A handle 2 10 is fixed on the outer wall of the collar 2 18, which can be used to conveniently lift the collar 2 18 upward.

[0023] In another embodiment of this utility model, an elastic pad 12 is provided between the conical ring 5 and the boss 2, which is sleeved on the outside of the oxygen sensor body 4. The elastic pad 12 has a certain elasticity in its thickness direction. A spring 7 is sleeved on the outside of the collar 18 and the handle 13. The spring 7 applies a downward pressure to the collar 18 and a lifting force to the collar 16. A detection end 15 is provided at the bottom of the oxygen sensor body 4, which extends into the interior of the vehicle exhaust pipe 1. A retaining ring 14 is fixed on the outer wall of the oxygen sensor body 4, and the retaining ring 14 is located at the top of the collar 16. The retaining ring 14 blocks the first collar 6; the side wall of the second collar 18 is provided with a limiting groove 8, and the side wall of the claw 3 is fixed with a limiting block 9. The limiting block 9 is located inside the limiting groove 8. The claw 3 is adapted to the limiting groove 8. When in use, the second collar 18 is lifted by the second handle 10, and the second handle 10 is brought close to the first handle 13. At this time, the claw 3 can correspond exactly to the limiting groove 8, which provides space for the claw 3 to disengage from the conical ring 5. The claw 3, the second collar 18, the first collar 6 and the conical ring 5 are all made of high temperature resistant material, and the claw 3 has a certain elastic deformation capability.

[0024] Working principle: When disassembling the oxygen sensor body 4, first lift the collar 18 using handle 10, bringing handle 10 close to handle 13. At this time, the pawl 3 corresponds to the limiting groove 8. Then, press down on handle 13, causing the conical surface 16 of collar 6 to squeeze the pawl 3, causing the pawl 3 to separate from the conical ring 5. At the same time, the elastic force of the elastic pad 12 on the oxygen sensor body 4 causes the pawl 3 and the conical ring 5 to misalign. Then, apply upward force to the oxygen sensor body 4, and the oxygen sensor body 4 and collar 6 can be pulled out from the inside of collar 18 at the same time. This makes disassembly and installation more convenient without the need for tools.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
