Description

Technical Field

[0001] This utility model relates to the field of seal collection devices, specifically a high-efficiency seal collection device for automobile exhaust detection. Background Technology

[0002] To perform monitoring, the "high-efficiency sealing and collection device for automotive exhaust testing" is inserted into the vehicle's exhaust pipe. This device typically consists of a flexible sealing plug, a guide rod, a sealing ring, and a pressure sensor. During testing, the exhaust pipe opening is pre-treated to remove foreign objects: use a dust-removing rubber ring or cloth to wipe away oil and carbon deposits from the inner wall of the exhaust pipe opening to prevent poor sealing or slippage. The sealing plug is then manually pushed in: gently push the plug with the guide cone structure at the front end into the exhaust pipe opening to a depth of 5–10 cm, ensuring the sealing ring is fully inside the pipe. Alignment angle: keep the plug coaxial with the exhaust pipe to avoid tilting that could lead to uneven sealing.

[0003] In the subsequent insertion and connection of the sampling tube: the center of the plug has a gas sampling channel, which is connected to the exhaust gas analyzer or air tightness tester through a quick connector. This insertion action is relatively large, which can easily cause the sealing plug inserted into the exhaust pipe to be pulled and loosened, affecting the accuracy of subsequent tests. Therefore, in order to address the above problems, a high-efficiency sealing sampling device for automobile exhaust testing is proposed. Utility Model Content

The end of the fork head 411 is fixedly connected to one end of the bogie 41. The other end of the bogie 41 is rotatably connected to one end of the positioning rod 412. The other end of the positioning rod 412 is fixedly connected to the inner wall of the sealing plug 1. The force-bearing component 5 includes: a guide frame 51, a second positioning rod 52, a shaft 521, and a threaded block 53. The frame of the force-bearing component 5 is fixedly connected to the end of the guide frame 51, the frame of the guide frame 51 is slidably connected to the end of the threaded block 53, the upper part of the frame of the force-bearing component 5 is rotatably connected to the end of the shaft 521, the middle part of the shaft 521 is fixedly connected to one end of the second positioning rod 52, and the other end of the second positioning rod 52 is fixedly connected to the inner wall of the sealing plug 1.

[0012] Working principle: When the sealing plug 1 is inserted into the exhaust pipe, the power component 2 is rotated, causing the first bevel tooth 22 to drive the second bevel tooth 31 to rotate. At this time, the double-headed power screw 3 drives the threaded blocks 53 at both ends to move synchronously toward the middle of the double-headed power screw 3. In this way, the threaded blocks 53 drive the sliding block 532 to rotate. At the same time, the sliding block 532 is rotatably connected to the steering column 531. The sliding block 532 will rotate and slide to connect the guide frame 51. The force-bearing component shaft 521 will restrict the rotation of the force-bearing component 5. In this way, the second bogie 42 drives the second fork head 421 to move toward the position of the extrusion piece 6. The linkage component 4 drives the first bogie 41 to extrude the extrusion piece 6. The positioning rod 412 will restrict the rotation of the first bogie 41. The first bogie 41 will extrude the extrusion piece 6. The extrusion piece 6 extrudes the second power rod 61. The second power rod 61 slides under the restriction of the fitting groove 11. The second power rod 61 drives the friction plate 612 to stick tightly to the inner wall of the exhaust pipe, thus preventing the sealing plug 1 from loosening and falling off. The double-headed power screw 3 drives the force-receiving component 5 to move, and the force-receiving component 5 drives the linkage component 4 to continuously squeeze the extrusion component 6. This allows the extrusion component 6 to tightly press against the inner wall of the car exhaust pipe. At the same time, the friction plate 612 is made of flexible plastic material, which can enhance the friction with the inner wall of the car exhaust pipe and prevent slippage. The double-headed power screw 3 is driven to rotate by the power component 2. The double-headed power screw 3 can simultaneously drive the force-bearing components 5 on both sides to move synchronously. The threaded connection between the power component 2 and the double-headed power screw 3 ensures that the force-bearing components 5 can be stably maintained in their state after the action, preventing them from loosening later.
