Description

Technical Field

[0001] This utility model relates to the field of automobile exhaust emission detection technology, specifically a motor vehicle exhaust emission collection device. Background Technology

[0002] With the improvement of living standards and the development of technology, automobiles have become widely used in life. The continuous increase in automobiles has also led to an increase in exhaust emissions. Exhaust emissions into the air cause environmental pollution and endanger human health. As a result, users are increasingly demanding high-quality exhaust gas detection and collection devices that are easy to collect. However, the connection between the exhaust gas detection and collection device and the automobile exhaust pipe is generally made using springs, which is not stable enough.

[0003] For example, an existing patent (publication number: CN214373669U) discloses a vehicle exhaust gas detection and collection device that facilitates exhaust gas collection. A connecting pipe is fixedly installed on the right side of the filter box. This device features a groove on the inner wall of the collection pipe, with a telescopic rod installed on the inner wall of the groove. The telescopic rod is connected to a clamping plate, and a flexible rod is installed on the end of the clamping plate near the telescopic rod. A spring is installed on the outer wall of the flexible rod, which is connected to the inner wall of a movable ring. This allows the device to adapt to vehicle exhaust pipes of different diameters, making exhaust gas collection easier. A limiting block is then installed on the inner wall of the movable ring.

[0004] However, the above-mentioned easy-to-collect vehicle exhaust gas detection and collection device still has some drawbacks in actual use: the two ends of the flexible rod on the easy-to-collect vehicle exhaust gas detection and collection device are respectively fixedly connected to the clamp and the movable ring, which makes the movable ring unable to rotate, resulting in motion interference; even if the movable ring can rotate, the setting of the spring makes the connection between the detection device and the exhaust pipe unstable when a large amount of exhaust gas suddenly surges out during detection.

[0005] To address this issue, we designed a vehicle exhaust gas collection device. Utility Model Content

[0006] The purpose of this invention is to provide a vehicle exhaust gas collection device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a motor vehicle exhaust gas collection device, including a collection pipe and a collection assembly disposed on one side of the collection pipe. The inner wall of the collection pipe is provided with a plurality of clamping assemblies, each of which includes a telescopic rod. The telescopic rod is fixedly installed on the inner ring of the collection pipe. A universal ball base is fixedly installed at the telescopic end of the telescopic rod. A limit opening is provided at the top of the universal ball base. A universal ball is snapped into and rotatably installed in the limit opening. A soft clamping plate is fixedly installed at the top of the universal ball. A bolt is abutted against the bottom of the soft clamping plate. The bolt is threaded into the collection pipe.

[0008] Furthermore, the soft clamp is made of fluororubber, and the outer surface of the soft clamp is provided with anti-slip texture, which increases the stability of clamping and makes the clamping of exhaust pipes with different curvatures more secure.

[0009] Furthermore, the collection assembly includes a filter box disposed on one side of the collection tube. A first connecting pipe is fixedly disposed at one end of the filter box, and a second connecting pipe is slidably connected to the other end of the first connecting pipe. A collection bag is disposed at the other end of the second connecting pipe.

[0010] Furthermore, the inner wall of the first connecting tube is provided with a sliding groove, and a damping rod return spring is fixedly installed inside the sliding groove. Slider blocks are symmetrically arranged at both ends of the second connecting tube. The sliders are slidably connected inside the first connecting tube, and the other end of the damping rod return spring is fixedly connected to one end of the slider.

[0011] Furthermore, the inner ring of one end of the second connecting pipe is provided with an internal thread, and the inside of the collection bag is provided with an external thread, and the collection bag is threadedly fitted onto the second connecting pipe.

[0012] Furthermore, the slider is slidably connected inside the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Tightening the bolts makes the top of the soft clamp plate fit against the outer wall of the exhaust pipe. At this time, the telescopic rod extends while the bolts are tightened. When the soft clamp plate is fitted against the outer wall of the exhaust pipe, it will inevitably produce an arc. The universal ball fixed to the bottom of the soft clamp plate will rotate so as to better fit against the outer wall of the exhaust pipe. When the collection and detection device is connected to the exhaust pipe to collect exhaust gas, the exhaust pipe will vibrate. The bolt connection relative to the spring will be more stable. At the same time, the universal ball can help the soft clamp plate fit tightly against the outer wall of the exhaust pipe.

[0014] 2. When exhaust gas is discharged, it will inevitably generate a certain impact force. The setting of the slide block damping rod and return spring can effectively play a buffering role. When the exhaust gas impacts the collection bag, the slider slides in the slide block under the impact, and the return spring is stretched. When the exhaust gas enters the collection bag, the impact force disappears and the return spring returns to its original position, which alleviates the impact of the exhaust gas and is conducive to the installation and fixation of the collection and detection device and the exhaust pipe to a certain extent.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a motor vehicle exhaust gas collection device, including a collection pipe 1 and a collection assembly disposed on one side of the collection pipe 1. The inner wall of the collection pipe 1 is provided with a plurality of clamping assemblies, each clamping assembly including a telescopic rod 2. The telescopic rod 2 is fixedly installed on the inner ring of the collection pipe 1. A universal ball base 3 is fixedly installed on the telescopic end of the telescopic rod 2. A limit port is opened on the top of the universal ball base 3. A universal ball 4 is snapped and rotatably installed in the limit port. A soft clamping plate 5 is fixedly installed on the top of the universal ball 4. A bolt 6 is abutted against the bottom of the soft clamping plate 5. The bolt 6 is threaded into the collection pipe 1. The soft clamping plate 5 is made of fluororubber, and the outer surface of the soft clamping plate 5 is provided with anti-slip texture.

[0022] In practice, tightening bolt 6 makes the top of the soft clamp 5 fit against the outer wall of the exhaust pipe. At the same time, the telescopic rod 2 extends as bolt 6 is tightened. When the soft clamp 5 fits against the outer wall of the exhaust pipe, it will inevitably produce an arc. The universal ball 4 fixedly connected to the bottom of the soft clamp 5 will rotate to better fit against the outer wall of the exhaust pipe. When the collection and detection device is connected to the exhaust pipe to collect exhaust gas, the exhaust pipe will vibrate. The connection between bolt 6 and spring will be more stable. At the same time, the universal ball 4 rolling inside the universal ball base 3 can help the soft clamp 5 fit tightly against the outer wall of the exhaust pipe.

[0023] See Figure 1-4 As shown, the collection assembly includes a filter box 7, which is disposed on one side of the collection pipe 1. A first connecting pipe 8 is fixedly disposed at one end of the filter box 7, and a second connecting pipe 9 is slidably connected to the other end of the first connecting pipe 8. A collection bag 14 is disposed at the other end of the second connecting pipe 9. A groove 10 is provided on the inner wall of the first connecting pipe 8, and a damping rod 12 and a return spring 13 are fixedly disposed inside the groove 10. Slider blocks 11 are symmetrically disposed at both ends of the second connecting pipe 9. The sliders 11 are slidably connected inside the first connecting pipe 8, and the other end of the damping rod 12 and the return spring 13 are fixedly connected to one end of the slider 11. The slider 11 is slidably connected inside the groove 10.

[0024] When exhaust gas is discharged, it inevitably generates a certain impact force. The sliding groove 10, slider 11, damping rod 12, and return spring 13 are designed to effectively buffer this impact. When the exhaust gas impacts the collection bag 14, the slider 11 slides within the sliding groove 10 under the impact, and the return spring 13 is stretched. When the exhaust gas enters the collection bag 14, the impact force disappears, and the return spring 13 returns to its original position, thus mitigating the impact of the exhaust gas and facilitating the installation and fixation of the collection and detection device and the exhaust pipe to a certain extent.

[0025] See Figure 1-4 The inner ring of one end of the second connecting pipe 9 is provided with an internal thread, and the inside of the collection bag 14 is provided with an external thread. The collection bag 14 is threadedly fitted onto the second connecting pipe 9.

[0026] Working principle: First, insert the car exhaust pipe into the collection pipe 1, tighten the bolt 6 so that the top of the soft clamp 5 is in contact with the outer wall of the exhaust pipe. At this time, the telescopic rod 2 extends as the bolt 6 is tightened. When the soft clamp 5 is in contact with the outer wall of the exhaust pipe, it will inevitably produce an arc. The universal ball 4 fixedly connected to the bottom of the soft clamp 5 will rotate so as to better fit with the outer wall of the exhaust pipe. For different exhaust pipes, their curvature and radius will be different. The bolt 6 is tightened by different distances to fix exhaust pipes of different sizes.

[0027] After the collection and detection device is installed, when the accelerator is revved, exhaust gas is discharged from the exhaust pipe. This discharge inevitably generates a certain impact force. The sliding groove 10, slider 11, damping rod 12, and return spring 13 effectively buffer this impact. When the exhaust gas impacts the collection bag 14, the slider 11 slides within the sliding groove 10, stretching the return spring 13. When the exhaust gas enters the collection bag 14, the impact force disappears, and the return spring 13 returns to its original position, thus repeatedly buffering the impact.
