[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] This utility model provides a positioning structure for an exhaust gas temperature sensor that is easy to assemble and disassemble. It includes an exhaust pipe 1, a positioning seat 2 fixedly connected to the side wall of the exhaust pipe 1, a sensor housing 3 detachably connected to the positioning seat 2, a data transmission line 301 installed at the right end of the sensor housing 3, a slider 4 fixedly connected to the outer wall of the sensor housing 3, and a groove 401 on the positioning seat 2 that mates with the slider 4. The slider 4 is slidably disposed in the groove 401. A protrusion 402 is fixedly connected to the inner wall of the groove 401, the protrusion 402 matching the shape of the slider 4. The protrusion 402 is made of magnet material, and the slider 4 is made of iron material. The four-phase adsorption limiting design, through the matching design of slider 4 and slide groove 401, enables the sensor housing 3 to be quickly positioned and initially fixed in the positioning seat 2. The protrusion 402 and slider 4 are matched in shape, and the design of protrusion 402 being made of magnetic material and slider 4 being made of iron material, allows protrusion 402 and slider 4 to automatically adsorb and limit each other after slider 4 slides into slide groove 401, which greatly enhances the stability of sensor housing 3 in positioning seat 2. The auxiliary block 403 fixedly connected to the outer wall of positioning seat 2 and the fastening block 5 detachably connected to sensor housing 3, through the cooperation of external thread 501 and internal thread 502, the abutment design of fastening block 5 and positioning seat 2, provides double protection for the fixation of sensor.

[0018] The easy-to-install exhaust gas temperature sensor positioning structure features a protrusion 402 on the sensor housing 3 during actual use. The positioning base 2 has a groove 401 that matches the protrusion 402, facilitating its sliding into the groove and providing guidance for the sensor housing 3 to enter the positioning base 2. A slider 4 is only located on one side of the sensor housing 3 to ensure the correct installation orientation of the sensor housing 3 relative to the positioning base 2, preventing incorrect installation. The groove 401 contains the protrusion 402, which attracts the slider 4. A limiting device is used to initially limit the sensor housing 3 within the positioning seat 2. An auxiliary block 403 is also provided on the positioning seat 2. A fastening block 5 is then screwed into the outer wall of the auxiliary block 403. The external thread 501 on the outer wall of the auxiliary block 403 and the internal thread 502 on the inner wall of the fastener cooperate to limit the fastening block 5 at the position of the auxiliary block 403, thus completing the final limiting of the sensor housing 3 within the positioning seat 2. This structural design enables quick installation and removal of the exhaust gas temperature sensor from the exhaust pipe 1. When installing the sensor, the slider 4 on the sensor housing 3 is aligned with the groove 401 on the positioning seat 2 and slid into the appropriate position. The magnetic protrusion 402 attracts the iron slider 4, completing the initial limiting. The fastening block 5 is then screwed into the auxiliary block 403. Through the cooperation of the external thread 501 and the internal thread 502, the fastening block 5 is tightly connected to the positioning seat 2, thus completing the final limiting of the sensor housing 3 within the positioning seat 2. The entire installation process is simple and quick, requiring no complicated tools or operations. Compared to conventional installations without positioning assistance structures, it not only improves work efficiency but also reduces maintenance costs.

[0019] Example 1 like Figure 1-4 As shown, an auxiliary block 403 is fixedly connected to the outer wall of the positioning base 2, and a fastening block 5 is detachably connected to the sensor housing 3. The outer wall of the auxiliary block 403 is provided with an external thread 501, and the inner wall of the fastening block 5 is provided with an internal thread 502. The external thread 501 and the internal thread 502 cooperate to limit the fastening block 5 at the position of the auxiliary block 403. After the fastening block 5 completes its limiting function, it abuts against the positioning base 2. A handle ring 6 is installed on the fastening block 5. The overall effect of Embodiment 1 is that, during use, by providing a handle ring 6 on the fastening block 5, the operator can more easily apply force when installing or removing the fastening block 5, thus improving the ease of operation. The design of the handle ring 6 also conforms to ergonomic principles, making the operation process more comfortable.

[0020] Working Principle: In actual operation, when installing an exhaust gas temperature sensor, the operator first aligns the slider on the sensor housing with the groove on the positioning seat and slides it into the appropriate position along the groove. The magnetic protrusion fixedly connected to the inner wall of the groove attracts the iron slider fixedly connected to the outer wall of the sensor housing, thus initially limiting the sensor housing in the positioning seat. The operator then screws the fastening block into the auxiliary block fixedly connected to the outer wall of the positioning seat. Because the auxiliary block has external threads on its outer wall and the fastening block has internal threads on its inner wall, the two work closely together to limit the fastening block at the position of the auxiliary block. After the fastening block completes its limiting function, it abuts tightly against the positioning seat, thus providing double protection for the final limiting of the sensor housing in the positioning seat.
