Description

Technical Field

[0001] This utility model relates to the field of exhaust gas collection technology, and in particular to a replaceable exhaust gas carbon component collection probe. Background Technology

[0002] In the fields of modern environmental protection and vehicle exhaust emission testing, the accurate collection and analysis of carbon components in exhaust gases is crucial. The exhaust carbon component collection probe, as a core component, directly affects the accuracy and efficiency of the test data. With increasingly stringent environmental regulations, higher demands are being placed on the performance and ease of use of exhaust carbon component collection probes.

[0003] Currently, most commercially available exhaust gas carbon component collection probes employ a fixed structure design, typically consisting of a probe body, connecting pipes, and mounting components. In practical use, the probe connects to the detection equipment via a specific interface, utilizing its internal sensing element to capture and preliminarily process carbon components in the exhaust gas before transmitting the collected sample to the detection instrument for analysis. Its working principle primarily relies on physical adsorption or chemical reactions within the probe to collect exhaust gas carbon components.

[0004] Existing exhaust gas carbon component sampling probes require maintenance personnel to use various tools and go through a complex disassembly process to remove the old probes and install new ones when they become worn, contaminated, or damaged due to long-term use. This not only increases maintenance costs but also affects the continuity and efficiency of exhaust gas detection work. Therefore, a replaceable exhaust gas carbon component sampling probe is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a replaceable exhaust gas carbon component collection probe, which aims to improve the problem that in the prior art, maintenance personnel need to use multiple tools to remove the old probe when replacing the probe, thus affecting the continuity and efficiency of exhaust gas detection work.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A replaceable exhaust carbon component collection probe includes a corrugated collection tube, one end of which is fixedly connected to a connector, and the other end of which is fixedly connected to a fixing sleeve. A sampling probe is provided on one side wall of the fixing sleeve, and the sampling probe has multiple through holes inside. A quick-release assembly is provided inside the fixing sleeve, and a fixing assembly is provided on one side wall of the fixing sleeve.

[0008] The quick-release assembly includes a positioning strip, the side wall of which is fixedly connected to one side wall of the fixing sleeve. A fixing seat is fixedly connected inside the fixing sleeve, a spring is fixedly connected to the side wall of the fixing seat, and a locking block is fixedly connected to one end of the spring. The side wall of the locking block is slidably connected inside the fixing sleeve.

[0015] As a further description of the above technical solution:

[0016] The fixed sleeve has a threaded groove on one side wall, and an adjusting nut is threadedly connected to one side wall of the fixed sleeve. The side wall of the adjusting nut is attached to the side wall of the sliding sleeve.

[0017] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by pulling the sampling probe, the locking block compresses the spring and slides along the inside of the fixing sleeve, causing the locking block to slide out from inside the sampling probe. At this time, the positioning strip can be pulled out from inside the sampling probe, and the old sampling probe can be removed, achieving the effect of quick probe replacement. This solves the problem that when some exhaust gas carbon component sampling probes are worn, contaminated, or damaged due to long-term use, maintenance personnel need to use multiple tools to remove the old probe, which affects the continuity and efficiency of exhaust gas detection work. The above structure improves the efficiency of probe replacement.

[0025] 2. In this utility model, by rotating the adjusting nut, it moves and squeezes the sliding sleeve, pushing the second connecting strip. The second connecting strip rotates and drives the first connecting strip, thereby tightening the fixing plate and clamping and fixing the exhaust pipe.

[0033] 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.

[0034] Reference Figures 1-4 This utility model provides an embodiment of a replaceable exhaust gas carbon component collection probe, including a corrugated collection tube 1. The corrugated collection tube 1 is used to transport exhaust gas. The flexible corrugated structure can adapt to different installation spaces and angle requirements, improving the applicability and flexibility of the probe. One end of the corrugated collection tube 1 is fixedly connected to a connector 2. The corrugated collection tube 1 works with the connector 2 to transmit exhaust gas, achieving the effect of transporting exhaust gas from the collection point to the subsequent treatment equipment. The other end of the corrugated collection tube 1 is fixedly connected to a fixing sleeve 3. A sampling probe 4 is provided on the side wall of the fixing sleeve 3. The sampling probe 4 has multiple through holes 5 inside. The sampling probe 4 works with the through holes 5 to collect exhaust gas, achieving the effect of allowing the exhaust gas to fully enter the probe. The fixing sleeve 3 is provided with a quick-release component inside and a fixing component is provided on the side wall of the fixing sleeve 3.

[0035] The quick-release assembly includes a positioning strip 6, whose sidewall is fixedly connected to the sidewall of the fixing sleeve 3. The positioning strip 6 is used to position the sampling probe 4, ensuring that the sampling probe 4 can be accurately aligned with the fixing sleeve 3 during installation. A fixing seat 7 is fixedly connected inside the fixing sleeve 3. A spring 8 is fixedly connected to the sidewall of the fixing seat 7. A locking block 9 is fixedly connected to one end of the spring 8. The locking block 9 is slidably connected to the inside of the fixing sleeve 3. The spring 8 provides elastic force, and its elastic deformation allows the locking block 9 to move accordingly during installation and removal, enabling quick installation and removal of the sampling probe 4. The positioning strip 6 and the locking block 9 are slidably connected to the inside of the sampling probe 4. The locking block 9, by cooperating with the locking groove inside the sampling probe 4, can firmly fix the sampling probe 4 to the fixing sleeve 3, ensuring that the sampling probe 4 will not loosen during the sampling process.

[0036] Reference Figure 5The fixing assembly includes a fixing plate 16, which is annularly arranged on the side wall of the fixing sleeve 3. The fixing plate 16 is used to wrap around the inside of the exhaust pipe, directly contacting and applying a fastening force to the exhaust pipe, providing a force point for fixing the probe and achieving the effect of stably installing the probe on the exhaust pipe. A fixing sleeve 2 10 is fixedly connected to the side wall of the fixing sleeve 3, and a sliding sleeve 11 is also connected to the side wall of the fixing sleeve 3. A threaded groove 12 is opened on the side wall of the fixing sleeve 3, and an adjusting nut 13 is threadedly connected to the side wall of the fixing sleeve 3. The side wall of the adjusting nut 13 fits against the side wall of the sliding sleeve 11. The adjusting nut 13 transmits the adjusting force, allowing the sliding sleeve 11 to slide in the direction of movement of the adjusting nut 13. To control the tightness of the fixing plate 16, a connecting strip 14 is rotatably connected to the side wall of the fixing sleeve 2 10. A connecting strip 2 15 is rotatably connected inside the connecting strip 14. One end of the connecting strip 14 is rotatably connected to the side wall of the fixing plate 16, and one end of the connecting strip 2 15 is rotatably connected to the side wall of the fixing plate 16. The side wall of the sliding sleeve 11 is slidably connected to the side wall of the fixing sleeve 1 3, and the other end of the connecting strip 2 15 is rotatably connected to the side wall of the sliding sleeve 11. When the sliding sleeve 11 slides under the action of the adjusting nut 13, it drives the connecting strip 2 15 to move. The connecting strip 2 15 then pulls the connecting strip 14, ultimately causing the fixing plate 16 to tighten or loosen. This achieves the effect of adaptively adjusting the clamping force according to the exhaust pipe with different diameters, and firmly fixing the probe.

[0037] Working Principle: When using this device, one end of the corrugated sampling tube 1 is connected to the exhaust gas detection equipment via connector 2, and the sampling probe 4 at the other end is inserted into the exhaust pipe. The exhaust gas enters the fixed sleeve 3 through multiple through holes 5 inside the sampling probe 4, and is then transported to the detection equipment via the corrugated sampling tube 1 to complete the collection of carbon components in the exhaust gas. The corrugated structure of the corrugated sampling tube 1 gives it a certain degree of flexibility, making it easy to arrange flexibly in different installation environments. When the probe is installed on the exhaust pipe, by rotating the adjusting nut 13, since the adjusting nut 13 is threadedly connected to the threaded groove 12 on the side wall of the fixed sleeve 3, the adjusting nut 13 moves along the side wall of the fixed sleeve 3 and squeezes the sliding sleeve 11. The sliding sleeve 11 slides on the side wall of the fixed sleeve 3, pushing the connecting strip 15. The connecting strip 15 rotates and drives the connecting strip 14, thereby... The fixing plate 16 is tightened to clamp and fix the exhaust pipe. The linkage structure composed of fixing sleeve 10, connecting strip 14, and connecting strip 15 can flexibly adjust the tightening degree of fixing plate 16 according to the diameter of the exhaust pipe to adapt to exhaust pipes of different sizes. When replacing the sampling probe 4, the sampling probe 4 is pulled, the locking block 9 compresses the spring 8 and slides along the inside of the fixing sleeve 3, so that the locking block 9 slides out from the inside of the sampling probe 4. At this time, the positioning strip 6 can be pulled out from the inside of the sampling probe 4, and the old sampling probe 4 can be removed. When installing the new sampling probe 4, the positioning strip 6 is aligned and inserted into the inside of the sampling probe 4. When the locking block 9 reaches the corresponding position, the spring 8 pushes the locking block 9 into the inside of the sampling probe 4 to achieve quick fixation. The positioning strip 6 plays a guiding and auxiliary positioning role to ensure that the sampling probe 4 is installed in an accurate position.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
