Abstract
Description
Technical Field
[0001] This utility model relates to the field of exhaust gas detection, and in particular to a quick installation structure for a motor vehicle exhaust carbon emission detection device. Background Technology
[0002] Exhaust carbon emission testing devices are used to monitor the concentration and emission of pollutants such as carbon dioxide and carbon monoxide in motor vehicle exhaust in real time. They achieve detection functions through gas collection, component analysis, and data processing. They are widely used in environmental supervision, vehicle maintenance, and other scenarios. Motor vehicle exhaust carbon emission testing devices use a quick-installation structure, mainly because it can significantly improve detection efficiency, meet the needs of high-frequency and mobile testing, be compatible with various vehicle models, adapt to differences in exhaust pipes, ensure the safety and reliability of the testing process, avoid equipment loosening and data deviation, reduce labor costs and operating threshold, support use by non-professionals, and also comply with the policy and regulations for non-destructive installation, which is in line with the development trend of intelligent testing.
[0003] The existing rapid installation structure for motor vehicle exhaust carbon emission detection devices combines mechanical innovation with intelligent auxiliary design. It achieves rapid positioning and fixation through magnetic or guiding structures, and uses technologies such as adaptive elastic clamps and vacuum adsorption to precisely lock and maintain dynamic stability. At the same time, it uses shock-absorbing and heat-insulating materials to isolate vibration and high temperature, and uses photoelectric, angle and other sensors and indicator systems to provide feedback on the installation status. With a modular design that allows for one-click unlocking, it can be quickly disassembled and reused. It meets the requirements of multi-scenario compatibility, zero-tool operation, reliable data and non-destructive installation, which greatly improves the efficiency and reliability of exhaust monitoring.
[0004] In the practical application of rapid installation structures for motor vehicle exhaust carbon emission testing devices, although they have achieved a certain degree of convenient installation through designs such as clamps and magnetic attraction, the problem of cross-pipe diameter compatibility has not been completely overcome. Currently, most structures can only cover a limited range of pipe diameters. When faced with different exhaust pipe diameters of cars, trucks, and special vehicles, it is still necessary to frequently replace the appropriate clamp modules or the entire installation assembly. In addition, although some elastic clamps claim to be adaptive to pipe diameter, under extreme pipe diameter differences, due to the limited elastic deformation limit of the structure, insufficient locking force or excessive compression may occur, which may lead to problems such as probe displacement and exhaust gas leakage. This not only affects the accuracy of data but also leads to increased equipment wear. This pseudo-adaptive status quo greatly reduces the efficiency of rapid installation structures and has become a key bottleneck restricting their further popularization in diversified testing scenarios.

[0032] 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.
[0033] Reference Figures 1-3 The present invention provides an embodiment of a quick installation structure for a motor vehicle exhaust carbon emission detection device, comprising an exhaust pipe 1, a support frame 2 at one end of the exhaust pipe 1 for connecting to a connecting column 3, a plurality of connecting columns 3 fixedly connected to the outer wall of the support frame 2 for accommodating telescopic components, a telescopic component inside each connecting column 3 for controlling the movement of a fixing ring 8, a connecting block 7 at one end of each connecting column 3 for connecting the fixing ring 8, a fixing ring 8 fixedly connected to one side of each connecting block 7 for fixing the device to the tail end of the exhaust pipe 1, and a detection component on one side of the support frame 2 for detecting data in the vehicle exhaust.
[0034] Each telescopic component includes a sliding rod 4, a limiting plate 5, and a spring 6. The outer wall of each sliding rod 4 is slidably connected to the inside of the connecting column 3 to connect to and move the fixing ring 8. One end of each sliding rod 4 is fixedly connected to one side of the connecting block 7. One side of each limiting plate 5 is fixedly connected to one end of the sliding rod 4 to limit the range of movement of the sliding rod 4. Each spring 6 is provided on the outer wall of the sliding rod 4 to provide elastic force to the sliding rod 4. One end of each spring 6 is fixedly connected to the inside of the connecting column 3, and the other end of each spring 6 is fixedly connected to one side of the limiting plate 5. The detection component includes a detector 9, a display screen 10, and an air passage 11. One end of the detector 9 is slidably connected to one side of the support frame 2 for detecting exhaust gas. The bottom of the display screen 10 is fixedly connected to the top of the exhaust pipe 1 for displaying the detected data. The air passage 11 is opened inside the detector 9 for the passage of exhaust gas.
[0035] Specifically, the testing personnel hold the fixing rings 8 with both hands and slowly pull them outward using the strength of their palms. As the movement progresses, the originally tight spacing between the fixing rings 8 gradually widens, adjusting them to a distance that matches the diameter of the exhaust pipe 1 to be tested. Then, the testing personnel place this adjusted device on the end of the exhaust pipe 1 and release the fixing rings 8. The built-in spring 6 quickly releases its rebound force, driving the fixing rings 8 to contract inward in a uniform and powerful manner. In an instant, the entire device is fixed to the end of the exhaust pipe 1, fitting perfectly, laying a solid and reliable foundation for subsequent accurate exhaust gas testing.
[0036] Reference Figure 4 and Figure 5 Each connecting post 3 has a connecting rod 12 fixedly connected to one side for connecting the detector 9. The connecting rods 12 are arranged in a circular array on one side of the support frame 2. Multiple limiting blocks 13 are slidably connected inside the detector 9 for fixing the connecting rods 12. The outer wall of each limiting block 13 is slidably connected to the inside of the connecting rod 12. Multiple sliding posts 14 are fixedly connected to both sides of each limiting block 13 to limit the movement range of the limiting block 13. The sliding posts 14 are arranged in a symmetrical array on both sides of the limiting block 13. Each of the 13 has a handle 15 fixedly connected to its top for pulling the limit block 13. The limit blocks 13 are arranged in a circular array inside the detector 9. Each sliding post 14 has a spring 16 on one side to provide elastic force to the limit block 13. One end of each spring 16 is fixedly connected to the inside of the detector 9, and the other end of each spring 16 is fixedly connected to the inside of the sliding post 14. The outer wall of each sliding post 14 is slidably connected to the inside of the detector 9. The sliding posts 14 are arranged in a parallel array on one side of the limit block 13.
[0037] Specifically, when the detector 9 needs maintenance, the maintenance personnel place their palms on the handle 15 and then firmly grasp it, pulling the limit block 13 outward. As the limit block 13 gradually comes out of the connecting rod 12, the originally tight locking structure is released. Then, the maintenance personnel wrap their arms around the detector 9 and gently move it outward. During this process, the connecting rod 12 is slowly pulled out of the detector 9. Finally, the detector 9 is successfully removed from the support frame 2. The entire disassembly process is smooth and precise, preparing for subsequent detailed maintenance work.
[0038] Working principle: During the quick installation of the motor vehicle exhaust carbon emission testing device, first hold the fixing ring 8 and pull it outward so that the distance between each fixing ring 8 becomes the same as the diameter of the exhaust pipe 1 to be connected. Then, put it on the end of the exhaust pipe 1 and release the fixing ring 8, so that it retracts inward under the action of spring 6 to fix the device to the end of the exhaust pipe 1. When it is necessary to remove the detector 9 for maintenance, first hold the handle 15 and pull the limiting block 13 outward so that the limiting block 13 disengages from the inside of the connecting rod 12. Then, hold the detector 9 and move it outward so that the connecting rod 12 is pulled out from the inside of the detector 9, so that the detector 9 is removed from the support frame 2, thereby completing the disassembly of the detector 9.
[0039] 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.
