[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figures 1-3This utility model provides an embodiment of an automatic vehicle exhaust gas stratification collection device, comprising a fixed platform 1, with multiple connecting shafts 2 fixedly connected to the side wall of the fixed platform 1. Each connecting shaft 2 has a connecting pipe 3 on its side wall, which is directly connected to the exhaust gas collector. A disassembly assembly is provided on the outer wall of the connecting shaft 2. The disassembly assembly includes multiple sleeves 18, which are slidably connected to the outer wall of the connecting shafts 2. The sliding connection of the sleeves 18 allows them to move flexibly when needed, ensuring easier disassembly. Each connecting shaft 2 and sleeve 18 has an inner groove 7, which provides a stable track for the sliding of the retaining shaft 8, ensuring accurate sliding and maintaining a stable connection. Multiple retaining shafts 8 are slidably connected inside the connecting shaft 2, and the retaining shafts 8 are slidably connected inside the inner groove 7. The sliding characteristics of the retaining shafts 8 enable quick locking and disassembly of the connecting pipes 3. A spring 4 is installed inside the sleeve 18. One end of the spring 4 is fixedly connected to the outer wall of the connecting shaft 2, and the other end is fixedly connected inside the spring 4. The elasticity of the spring 4 ensures that after the retaining ring 6 passes the initial position of the retaining shaft 8, the sleeve 18 can be automatically pushed back and quickly disassembled, thus achieving stable and efficient operation. A retaining pin 5 is fixedly connected to one end of the connecting tube 3, and a retaining ring 6 is fixedly connected to the outer wall of the retaining pin 5. The design of the retaining ring 6 ensures that the retaining pin 5 can be accurately inserted into the groove of the retaining ring 6 during the connection process, ensuring the firmness of the connection. A fixing component is provided on the side wall of the fixing platform 1, which effectively ensures that the entire device does not shift during use.
[0032] Specifically, when installing the connecting pipe 3, insert the locking pin 5 at one end into the port of the connecting shaft 2. The retaining ring 6 on the outer wall of the locking pin 5 enters the inner groove 7 inside the connecting shaft 2 and the sleeve 18 along with the locking pin 5. The retaining ring 6 presses against the retaining shaft 8 inside the connecting shaft 2, causing the retaining shaft 8 to slide into the inner groove 7 and compress the spring 4 inside the sleeve 18. After the retaining ring 6 passes the initial position of the retaining shaft 8, the spring 4 returns to its original position and pushes the sleeve 18 to slide along the outer wall of the connecting shaft 2 towards the port. Under the limiting action of the sleeve 18, the retaining shaft 8 pops out and locks the groove of the retaining ring 6, thereby achieving a quick lock between the connecting pipe 3 and the connecting shaft 2. When disassembling, manually pull the sleeve 18 away from the connecting shaft 2 to compress the spring 4, expanding the space in the inner groove 7 of the sleeve 18. The retaining shaft 8 loses its limiting action and slides into the inner groove 7, releasing the lock on the retaining ring 6. At this point, the locking pin 5 can be pulled out directly to complete the disassembly. This design allows the connecting pipe 3 to connect and disconnect from the collector more quickly during vehicle testing, simplifying the operation steps and improving the efficiency of exhaust gas collection.
[0033] Reference Figure 4 and Figure 5The fixing assembly includes multiple slides 14, which are slidably connected to the side wall of the fixing platform 1. An electric motor 9 is fixedly connected inside the fixing platform 1. A rotating plate 10 is fixedly connected to the output end of the electric motor 9. Multiple fixed shafts 11 are fixedly connected inside the rotating plate 10. A rotating rod 12 is rotatably connected to the outer wall of each fixed shaft 11. Multiple straight grooves 13 are opened inside the fixing platform 1. A pulley 15 is rotatably connected to the side wall of each slide 14. The pulley 15 is slidably connected inside the straight groove 13. A side frame 16 is fixedly connected to the side wall of each slide 14. The other end of the rotating rod 12 is rotatably connected to the side wall of the side frame 16. A clamping plate 17 is fixedly connected to the side wall of each side frame 16.
[0034] Specifically, when fixing the testing equipment, the electric motor 9 inside the fixing platform 1 is started. Its output end drives the rotating plate 10 to rotate. The fixed shaft 11 inside the rotating plate 10 rotates with the rotating plate 10 and pushes the rotating rod 12 to swing around the fixed shaft 11. The other end of the rotating rod 12 pushes the side frame 16 and the slide table 14 to slide along the side wall of the fixing platform 1. The pulley 15 on the side wall of the slide table 14 moves smoothly in the straight groove 13 inside the fixing platform 1. The two side frames 16 drive the clamping plate 17 to move towards the center until the equipment is clamped. When releasing, the electric motor 9 rotates in the opposite direction, the rotating plate 10 drives the fixed shaft 11 to rotate in the opposite direction, and the rotating rod 12 pulls the side frame 16 and the slide table 14 to move outward along the straight groove 13. The clamping plate 17 moves away from the equipment with the side frame 16, thereby releasing the clamping force and completing the release of the equipment. This design ensures that the equipment is stably supported during the fixing process, avoiding vibration or displacement caused by uneven clamping, thereby effectively improving the stability and reliability of the equipment and ensuring the accuracy and safety of the data collection process.
[0035] Working principle: When installing the connecting pipe 3, insert the locking pin 5 at one end into the port of the connecting shaft 2. The retaining ring 6 on the outer wall of the locking pin 5 enters the inner groove 7 inside the connecting shaft 2 and the sleeve 18 along with the locking pin 5. The retaining ring 6 squeezes the retaining shaft 8 inside the connecting shaft 2, causing the retaining shaft 8 to slide into the inner groove 7 and compress the spring 4 inside the sleeve 18. When the retaining ring 6 passes the initial position of the retaining shaft 8, the spring 4 returns to its original position and pushes the sleeve 18 to slide along the outer wall of the connecting shaft 2 towards the port. Under the limiting action of the sleeve 18, the retaining shaft 8 pops out and locks the groove of the retaining ring 6, realizing the quick locking of the connecting pipe 3 and the connecting shaft 2. When disassembling, manually pull the sleeve 18 away from the connecting shaft 2 to compress the spring 4. The space in the inner groove 7 of the sleeve 18 expands, causing the retaining shaft 8 to lose its limiting action and slide into the inner groove 7, releasing the lock on the retaining ring 6. The locking pin 5 can then be pulled out directly to complete the disassembly, allowing for faster completion of the process during vehicle inspection. The connection and disconnection of the collector improves the efficiency and accuracy of exhaust gas collection. When fixing the detection equipment, the electric motor 9 inside the fixed platform 1 is started, and its output end drives the rotating plate 10 to rotate. The fixed shaft 11 inside the rotating plate 10 rotates with the rotating plate 10 and pushes the rotating rod 12 to swing around the fixed shaft 11. The other end of the rotating rod 12 pushes the side frame 16 and the slide table 14 to slide along the side wall of the fixed platform 1. The pulley 15 on the side wall of the slide table 14 moves smoothly in the straight groove 13 inside the fixed platform 1. The two side frames 16 drive the clamping plate 17 to move closer to the center until the equipment is clamped. When releasing, the electric motor 9 rotates in the opposite direction, the rotating plate 10 drives the fixed shaft 11 to rotate in the opposite direction, and the rotating rod 12 pulls the side frame 16 and the slide table 14 to move outward along the straight groove 13. The clamping plate 17 moves away from the equipment with the side frame 16 and releases the clamping force, effectively improving the stability and reliability of the equipment, thereby improving the overall quality and safety of emission collection.
