Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine exhaust temperature detection, and more specifically, to a diesel engine exhaust temperature detection device. Background Art

[0002] At the current level of technology, diesel engine exhaust temperature detection devices usually use sensors to measure temperature. However, there are some problems with this type of sensor in practical applications. First, due to the material and structural characteristics of the sensor, they are often fragile. This means that under high temperature, high pressure and corrosive environments, the sensor is easily damaged, resulting in inaccurate measurements or complete failure. Especially in harsh environments such as diesel engine exhaust pipes, the service life of the sensor may be greatly shortened.

[0003] Secondly, the rigid connection of the sensor will also cause certain problems. Since the sensor needs to be fixed in the exhaust pipe or other high-temperature areas, the traditional rigid connection method may cause additional stress on the sensor, thereby increasing the risk of sensor damage. Once the sensor is damaged, it will not only affect the accurate measurement of temperature, but may also cause the entire detection device to fail, thus affecting the normal operation and safety of the diesel engine.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a detection device for diesel engine exhaust temperature, which has the following beneficial effects:

[0017] 1. The design of the mounting mechanism makes the fixation of the sensor more flexible and stable. By rotating the hexagonal sleeve, the adjusting spring will press against the vertical bar, thereby driving the rotation of the insertion sleeve, so that the elastic bar is clamped on the sensor, thereby completing the fixation of the sensor. This design allows the user to adjust the fixing force as needed to avoid damage to the sensor due to excessive clamping force. At the same time, the unfastening mechanism of the adjusting spring and the vertical bar also ensures that the pressure can be automatically released when the rotation force is too large, further protecting the safety of the sensor.

[0018] 2. The clamping mechanism realizes a close connection between the sensor and the fixed sleeve through the cooperation of the follower sleeve and the fitting ring. The interaction between the vertical bar of the follower sleeve and the adjusting spring ensures the stability and safety of the sensor when it is fixed. At the same time, by rotating the middle sleeve, the position of the lever can be changed, and then the fixing force of the adjusting spring can be adjusted, so that the user can adjust the clamping force according to the actual situation to achieve the best fixing effect. This design not only ensures the stable fixation of the sensor, but also avoids damage to the sensor caused by excessive clamping force.

[0019] 3. The synchronization mechanism realizes the effective fixation of the hexagonal sleeve through the cooperation of the lifting sleeve and the insertion rod. When the hexagonal sleeve needs to be adjusted and fixed, the insertion rod on the lifting sleeve is slidably connected to the insertion hole at the lower end of the positioning sleeve, and then drives the lifting sleeve to move upward, so that the insertion rod is inserted into the insertion hole at the upper end, thereby completing the fixation of the hexagonal sleeve. This design ensures the stability of the hexagonal sleeve during the adjustment process and avoids damage to the sensor or other components due to excessive clamping force. At the same time, the synchronization mechanism is easy to operate, which improves the reliability and safety of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The follower sleeve 13 is installed on the fitting ring 14. The fitting ring 14 abuts against the fixed sleeve 1. A plurality of vertical bars 15 are equidistantly arranged on the side wall of the follower sleeve 13. A plurality of adjustment springs 16 are equidistantly arranged on the inner wall of the rotating sleeve 2. The adjustment springs 16 abut against the vertical bars 15. An insertion sleeve 17 is arranged on the follower sleeve 13. A plurality of elastic bars 18 are arranged on the insertion sleeve 17. The plurality of elastic bars 18 abut against the side walls of the sensor respectively. An inner sleeve 19 is respectively provided, and a bottom sleeve 20 is threadedly provided on the inner sleeve 19, and the bottom sleeve 20 is fitted on the lower end surface of the fixed sleeve 1. The synchronization mechanism includes a lifting sleeve 21 and an insertion rod 22. The lifting sleeve 21 is slidably connected to the fixed sleeve 1.

A positioning sleeve 23 is provided on the fixed sleeve 1, and a plurality of insertion holes 24 are respectively opened on the positioning sleeve 23 and the hexagonal sleeve 9, and the insertion rod 22 is slidably connected in the insertion hole 24.

[0030] In this embodiment, when the sensor needs to be fixed, the hexagonal sleeve 9 is first rotated, and then the adjusting spring 16 is driven to press against the vertical bar 15, and then the insertion sleeve 17 is driven to rotate, and then the multiple elastic strips 18 are driven to rotate, so that the elastic strips 18 are stuck on the sensor, thereby completing the fixation of the sensor. When the rotation force is too large, the adjusting spring 16 will disengage from the vertical bar 15, thereby avoiding excessive clamping force. When the disengagement force of the adjusting spring 16 and the vertical bar 15 needs to be changed, first, the rotation of the multiple levers 4 can be driven by rotating the intermediate sleeve 3.

Therefore, the sensor can be effectively fixed, avoiding damage caused by excessive clamping force.

[0032] In summary, when the overall equipment is in use or running: when the sensor needs to be fixed, first rotate the hexagonal sleeve 9, which will then drive the adjusting spring 16 to press against the vertical bar 15, and then drive the insertion sleeve 17 to rotate, and then drive the rotation of multiple elastic strips 18, so that the elastic strips 18 are stuck on the sensor, thereby completing the fixation of the sensor. When the rotation force is too large, the adjusting spring 16 will disengage from the vertical bar 15, thereby avoiding excessive clamping force. When the disengagement force of the adjusting spring 16 and the vertical bar 15 needs to be changed, first, the rotation of multiple levers 4 can be driven by rotating the intermediate sleeve 3. Since the lever 4 presses against the adjusting spring 16, the fixing force of the adjusting spring 16 can be increased by changing the position of the lever 4, and then the follow-up ball 11 on the intermediate sleeve 3 is stuck in the positioning hole 12, and the limit sleeve 101 is threadedly connected to the rotating sleeve 2, so that the contact ring 8 is pressed on the intermediate sleeve 3, thereby completing the adjustment process.

[0033] When it is necessary to complete the adjustment of the hexagonal sleeve 9 for fixing, the insertion rod 22 on the lifting sleeve 21 is slidably connected to the insertion hole 24 at the lower end of the positioning sleeve 23, and then the lifting sleeve 21 is driven to move upward, so that the insertion rod 22 is inserted into the insertion hole 24 at the upper end, thereby completing the fixing of the hexagonal sleeve 9. Therefore, the sensor can be effectively fixed, avoiding damage caused by excessive clamping force.
